Vehicle underbodies made from natural fibers and recycled plastics

In collaboration with industrial partners, researchers at the Fraunhofer WKI have developed a vehicle underbody made from natural fibers and recycled plastics for automotive construction. The focus at the Fraunhofer WKI was directed at the development of the materials for injection molding as well as the hydrophobization of flax and hemp fibers for natural-fiber-reinforced mixed-fiber non-wovens.

The component fulfills the stringent technical requirements in the underbody area and could replace conventional lightweight vehicle underbodies in the future. With this development, the climate and environmental balance is optimized throughout the entire product life cycle.

In collaboration with industrial partners, researchers at the Fraunhofer WKI have developed a vehicle underbody made from natural fibers and recycled plastics for automotive construction. The focus at the Fraunhofer WKI was directed at the development of the materials for injection molding as well as the hydrophobization of flax and hemp fibers for natural-fiber-reinforced mixed-fiber non-wovens.

The component fulfills the stringent technical requirements in the underbody area and could replace conventional lightweight vehicle underbodies in the future. With this development, the climate and environmental balance is optimized throughout the entire product life cycle.

The project partners Fraunhofer WKI, Thuringian Institute for Textile and Plastics Research (TITK), Röchling Automotive SE & Co. KG, BBP Kunststoffwerk Marbach Baier GmbH and Audi AG have succeeded in developing a sustainable overall concept for vehicle underbodies. The researchers have thereby taken a challenging component group with a high plastic content and made it accessible for the utilization of natural materials. Until now, natural-fiber-reinforced plastics have predominantly been used in cars for trim parts without significant mechanical functions. Structural components such as vehicle underbodies are, however, exposed to enormous loads and place high demands on the bending and crash behavior of the material. In modern lightweight vehicle concepts, high-performance materials made from glass-fiber-reinforced plastics are therefore utilized.

The project team was able to replace the glass fibers with natural materials such as flax, hemp and cellulose fibers and to produce underbody components with a natural-fiber content of up to 45%. In the area of polymers, virgin polypropylene was completely dispensed with and solely recyclates were utilized. All the challenges associated with this material changeover – both the lower initial mechanical properties of the materials and the temporally restricted processing windows – were solved by means of skillful compound combinations.

At the Fraunhofer WKI, materials for injection molding were developed. “Natural-fiber injection-molded compounds have so far been known primarily for their increased strength and stiffness compared to non-reinforced polymers. In the development of the vehicle underbody, we have furthermore succeeded in fulfilling the stringent requirements for low-temperature impact strength through an innovative combination of selected post-consumer recyclates (PCR) as a matrix and natural fibers of varying degrees of purity - without forfeiting the required stiffness and strength,” explained Moritz Micke-Camuz, Project Manager at the Fraunhofer WKI.

Within the framework of the development, fiber-composite components made from natural-fiber-reinforced mixed-fiber non-wovens (lightweight-reinforced thermoplastic, LWRT) were realized for the first time at the TITK and at Röchling. The developed product not only fulfills the mechanical requirements: It also withstands in particular the challenges posed by the humid environment in which it is used. For the hydrophobization of flax and hemp fibers for LWRT components, a continuous furfurylation process was developed at the Fraunhofer WKI. Through furfurylation, moisture absorption can be reduced by up to 35 percent without impairment of the bending strength of the subsequent components. The furfurylated fiber material can also be easily processed on a non-woven production line.

The prototype components produced were subsequently extensively tested both at component level and in road tests. Amongst others, the vehicles from the VW Group’s new “Premium Platform Electric” (PPE) were used for this purpose. Long-term experience has already been gathered within the framework of the series testing. The gratifying result of these tests: The newly developed biocomposites fulfill all standard requirements for underbody components and have proven to be suitable for series production. Neither the use of natural fibers nor of (post-consumer) recyclates leads to a significant impairment of the properties.

One major advantage of the innovation is the significantly improved carbon footprint: Compared to series production, 10.5 kilograms of virgin material (PP/glass fiber) can be replaced by 4.2 kilograms of natural fibers and 6.3 kilograms of post-consumer recyclate. As a result, CO2 emissions during production, use and product life have been reduced by up to 40 percent.

Within the scope of the development project, an innovative, holistic overall concept for vehicle underbodies, including recycling with cascading re-use of the components, was developed. From a technical point of view, vehicle underbodies can be manufactured entirely from the new, high-performance lightweight bio construction material in the future.

The project was funded by the German Federal Ministry for Economic Affairs and Climate Action (BMWK) via the project management organization TÜV Rheinland.

BakeTex: Textile baking mat supports bakeries in saving energy

The ongoing energy crisis is increasingly pushing the bakery trade to its limits. Bakeries everywhere are having to close because they can no longer afford the sharp rise in the cost of electricity and gas. The use of energy-efficient ovens and the optimisation of production processes are important components that help to save energy. Researchers at the Fraunhofer Application Centre for Textile Fibre Ceramics TFK in Münchberg have now developed another building block: a textile baking base.
 
In bakeries, trays are normally used as a base for the baked goods in combination with baking paper or flour, which not only leads to large amounts of waste, but also to health problems (baker's asthma). The baking trays are also heavy and their mass increases the energy consumption in the oven, as they have to be heated with every baking process.

The ongoing energy crisis is increasingly pushing the bakery trade to its limits. Bakeries everywhere are having to close because they can no longer afford the sharp rise in the cost of electricity and gas.

Researchers at the Fraunhofer Application Centre for Textile Fibre Ceramics TFK in Münchberg have now developed another building block: a textile baking base.
 
In bakeries, trays are normally used as a base for the baked goods in combination with baking paper or flour, which not only leads to large amounts of waste, but also to health problems (baker's asthma). The baking trays are also heavy and their mass increases the energy consumption in the oven, as they have to be heated with every baking process.

With this in mind, the Bavarian Research Foundation approved a research project in 2021 to develop an alternative to conventional baking trays, which was successfully completed in 2023. The project partners were the Fraunhofer Application Centre for Textile Fibre Ceramics TFK from Münchberg, Fickenschers Backhaus GmbH from Münchberg and Weberei Wilhelm Zuleeg GmbH from Helmbrechts.

The aim of the project was to develop an energy-saving, pollutant-free and reusable textile baking mat with an integrated non-stick effect for use in industrial bakeries. Lightweight and heat-resistant textiles offer the potential to lower the preheating temperature in the oven and thus reduce energy consumption.
 
In a first step, a thin para-aramid fabric made of 120 g/m² long staple fibre yarn was therefore produced and stretched on a metallic frame. "The leno weave proved to be particularly suitable for the weave. Its characteristic lattice structure ensures that the textile is not only light but also permeable to air," says Silke Grosch from the Fraunhofer Application Centre TFK.

"In addition, by fixing the threads in place, the fabric cannot warp during washing and retains its shape for a long time." Finally, a full-surface silicone coating ensures that the baked goods do not stick to the baking base. This means that the previously necessary baking paper and flour layer can be dispensed with. To ensure that the rolls come out of the oven just as crispy and brown as with a standard baking tray, only the baking programme needs to be adjusted. Another key advantage of the textile baking tray is that it can be folded and therefore stored in a space-saving manner.

In the course of the fourth industrial revolution (Industry 4.0), the baking tray will be equipped with intelligent additional functions. On the one hand, the production data in the bakery can be determined using RFID chips or QR codes, and on the other hand, baked goods can be advertised in a targeted manner using customised branding.

Prof. Dr Frank Ficker, Head of the Fraunhofer Application Centre TFK, sums up: "With the textile baking base, we have developed a contemporary and resource-saving product together with our project partners that is characterised by its low weight and high flexibility. Together with the potential energy savings, this makes it interesting for many bakeries."

The Fraunhofer Application Centre for Textile Fibre Ceramics TFK in Münchberg specialises in the development, manufacture and testing of textile ceramic components. It is part of the Fraunhofer Centre for High Temperature Lightweight Construction HTL in Bayreuth, a facility of the Fraunhofer Institute for Silicate Research ISC with headquarters in Würzburg.

JUMBO-Textil: "For us, leadership means team development."

With its high-quality technical narrow textiles, JUMBO-Textil stands for high-tech - whether woven, braided or knitted. As an elastic specialist and solution partner, the company develops and produces individual innovations for customers worldwide. The 70-strong team must be as diverse and flexible as the products it designs. Textination spoke to industrial engineer Carl Mrusek about the current challenges facing family businesses. Carl Mrusek, who has been Chief Sales Officer (CSO) at Textation Group GmbH & Co. KG, to which JUMBO-Textil belongs, for almost a year now, is in charge of strategic corporate development as well as other areas of responsibility.

 

With its high-quality technical narrow textiles, JUMBO-Textil stands for high-tech - whether woven, braided or knitted. As an elastic specialist and solution partner, the company develops and produces individual innovations for customers worldwide. The 70-strong team must be as diverse and flexible as the products it designs. Textination spoke to industrial engineer Carl Mrusek about the current challenges facing family businesses. Carl Mrusek, who has been Chief Sales Officer (CSO) at Textation Group GmbH & Co. KG, to which JUMBO-Textil belongs, for almost a year now, is in charge of strategic corporate development as well as other areas of responsibility.

 

"In a family business, tradition is the foundation, innovation is the way forward," they say. The image of family-run companies has changed significantly in recent years - old-fashioned values and outdated business concepts have given way to a strong corporate culture, a strong sense of regional responsibility and sustainable planning. How does JUMBO-Textil combine its corporate values and traditions with a contemporary management style?

Carl Mrusek: As a family business, there is a close bond between the employees and the company and vice versa; the continuity of human relationships is important and valuable. JUMBO-Textil also has a tradition of one thing in particular: contemporary corporate management, both technically and professionally, as well as in terms of management style and values. Especially in a family business, which is often managed by the same person for decades, it is crucial to question corporate values and management style and to promote change. A company that has been operating successfully internationally for almost 115 years must be adaptable. For us, reacting quickly to changes, even anticipating them and moving forward accordingly, is at the heart of smart business practices. The specialization in elastics in the 1920s is an example of the foresighted power of change, as is the strategically important turn to technical textiles in the 1970s. A recent example is the merger with vombaur under the umbrella of the Textation Group.

The most important thing in any company is its employees. We would not be able to attract and retain them with outdated traditions and working methods. For us, the focus is not on the company management, but on joint success, and in a complex world, this is usually the result of successful cooperation and not an announcement from the boss. Leadership clearly means setting and pursuing strategic goals, but today it also means team development. Finding the best people, bringing them together and motivating them to achieve the goal.

 

Team spirit and vision development: How do you achieve this at JUMBO-Textil?

Carl Mrusek: As a team! JUMBO-Textil has systematically expanded its management team. In addition to the Managing Director, our CEO Andreas Kielholz, the Chief Operational Officer Patrick Kielholz, the Chief Financial Officer Ralph Cammerath, the Chief Technology Officer Dr. Sven Schöfer and myself as Chief Sales Officer work here. This shows that we are convinced of the idea of cooperation: We also work together on corporate development and strategic issues. The same applies to the individual teams - in organizational specialist teams or in interdisciplinary project teams. The tasks for which we are responsible may be different, but each is equally important.

 

Is that why you start the introduction of contact persons on your website with the Junior Sales Manager? And the C-level representatives are at the end?

Carl Mrusek: Yes, all JUMBO-Textil heads are the head of the company for us. All JUMBO-Textil faces represent the company. This is also reflected in the order of the contact persons on the website. Visitors should be able to quickly find the person who can help them and not find out who runs the company. That's what the legal notice is for. (laughs)

 

What is JUMBO-Textil's mission statement and vision for the future, and what needs to change in order to achieve this vision?

Carl Mrusek: We are currently working on the strategic direction of the Textation Group, which JUMBO-Textil GmbH & Co. KG and vombaur GmbH & Co. KG are part of. In this context, we have developed the Group's corporate vision and mission and updated our mission statement. This serves as a foundation for strategy development and is only sustainable if employees are involved in this process through surveys and workshops. I don't want to give too much away yet, but this much is already clear: strong teams, the right people in the right place, taking responsibility at all levels, sustainability as the basis for innovation - these will be the four cornerstones. You can already see from this: To achieve our vision, we cannot flip a switch. We must always remain open to change, always new - from product development to personnel recruitment. But as I said, we have a tradition of doing this.

 

JUMBO-Textil is not an industry specialist, but combines expertise for demanding high-tech narrow textiles. Who is in charge of challenging customer projects - do you decide in a team or rather top-down, where is the responsibility for an order placed?

Carl Mrusek: As a team, we decide which projects to implement and how to prioritize them. The corporate strategy determines the "direction of travel". In addition to the sales side, the development side of new projects also plays a decisive role. I therefore coordinate intensively with Dr. Sven Schöfer (CTO) and his team, as the focus here is on the technical development and implementation of our products. In the end, project processing is always a team effort between Sales and Development in close cooperation with Production..

 

Between above-standard pay, a 4-day week and the much-vaunted work-life balance in the current situation on the job market, companies are more likely to be in the position of applicants than vice versa. What are you doing to remain attractive as an employer for new colleagues? And how do you keep the enthusiasm of your skilled employees at a consistently high level?

Carl Mrusek: An important approach for us is education. Training young people and proving to them during their apprenticeship: JUMBO-Textil is your place to be. We therefore already start recruiting skilled workers through our school visits and school internships. As a state-of-the-art company, we offer an attractive salary level and a pleasant and healthy working environment.

Applicants today also often want to organize their working hours and work arrangements individually and flexibly, for a variety of reasons. With modern working models and thanks to our ongoing progress in digitalization, we support them wherever possible. People also want to work for a company that they can identify with. Environmental and climate protection are just as important to our employees and applicants as social standards in our supply chain. The fact that we have set ourselves ambitious goals with our sustainability strategy and are consistently pursuing them with firmly scheduled steps - our climate-neutral energy generation is a concrete example that has already been implemented. Furthermore, we vigorously encourage our business partners to respect human and employee rights and are committed to the Code of Conduct of the German textile and fashion industry. All of this helps us to recruit staff.

 

What larger, more capital-intensive companies can partially make up for with financial resources, SMEs have to manage through agility and adaptability - especially in situations of crisis. To what extent are these requirements also reflected in your organizational structure and the requirements profile for employees?

Carl Mrusek: Exactly, that is the advantage that family businesses have over large corporations: We can make decisions quickly and react on a daily basis if necessary. Hierarchies are flat and coordination processes are short. An exciting suggestion doesn't have to be prepared by agencies and coordinated across several levels before it is approved by the management and can be implemented. The go-ahead can also come immediately over lunch: "Great idea, we'll do it." In a corporate group, this fails because only very few employees have the opportunity to have lunch with the management. - And we only talk about business in exceptional cases. Most of the time, the break is about family, the weather, sports and leisure plans - lunch topics, in other words. - We need responsible team players who are willing to make a change. People who work with others on an equal footing, who are committed to the company and its goals with drive and expertise and who are keen to try new things.

 

It now takes much more than a fruit basket and a gym to motivate current and potential employees. Working in a meaningful way and participating in a climate-friendly transformation is particularly important to many people. What does JUMBO-Textil do specifically to not just quote SDGs in a statement, but to live them in everyday company life?

Carl Mrusek: We have set ourselves a specific climate target: By 2035, our administrative and production operations at our headquarters will be climate-neutral. Realistic steps have been defined to achieve this. We have already achieved an important interim goal: at our headquarters in Sprockhövel, we only use green electricity from the sun, wind and water. We offset the unavoidable emissions for our heat generation with CO2 compensation services. We are also developing more and more products from recyclable and recycled materials. Our vehicle fleet is currently being converted to purely electric or hybrid models.

 

Diversification and internationalization are part of every corporate strategy these days. But what do these terms mean for the management style of a medium-sized company in Sprockhövel? Do you consciously build interdisciplinary international teams?

Carl Mrusek: We live in a hyper-diverse society. This is also reflected in our company. Our teams consist of people with different international backgrounds, without us having to actively control this. The age structure is now also very mixed. We see the different perspectives as an asset, an opportunity and a success factor. We - and that ultimately means our customers and their projects - benefit from the variety of perspectives that flow into our solutions. As with many companies in the technical textiles sector, the proportion of women in some teams is still somewhat unbalanced. However, it is fortunately increasing steadily.

 

Generational change and succession planning are core issues for family-run companies. How important is it for JUMBO-Textil to professionalize its management team and to what extent is the company open to external specialists and managers?

Carl Mrusek: A company that closes its doors to external specialists and managers is also closing a door to success. That would be foolish. At JUMBO-Textil, we try to combine and balance the close ties, personal continuity and flexibility of a family-run company, the passion and innovative spirit of a start-up and the solidity and financial strength of a group. With Patrick Kielholz as COO, the next generation of the family is represented at management level, as is the external view and the diversity of perspectives provided by the other new members at C-level. The Textation Group, which also includes Patrick Kielholz's brother Kevin Kielholz, supports the company and enables it to think and act bigger than medium-sized family businesses often do. JUMBO-Textil is an elastic specialist. And what distinguishes our product also distinguishes us as an organization. We span the advantages of a family business as well as those of a start-up and a group. If I may use the image of elasticity here and not stretch it too far. (laughs)

Interview with vombaur - pioneers in special textiles
Technical narrow textiles, custom solutions, medium-sized textile producer and development partner for filtration textiles, composite textiles and industrial textiles: vombaur. Digitalisation, sustainability, energy prices, pioneering work and unbroken enthusiasm – Textination spoke to two passionate textile professionals: Carl Mrusek, Chief Sales Officer (CSO), and Johannes Kauschinger, Sales Manager for Composites and Industrial Textiles, at vombaur GmbH, which, as well as JUMBO-Textil, belongs to the Textation Group.
 
If you look back at your history and thus to the beginnings of the 19th century, you will see a ribbon manufactory and, from 1855, a production of silk and hat bands. Today you produce filtration textiles, industrial textiles and composites textiles. Although you still produce narrow textiles today, the motto "Transformation as an opportunity" seems to be a lived reality at vombaur.
 
Carl Mrusek, Chief Sales Officer: Yes, vombaur has changed a few times in its almost 220-year history.  Yet the company has always remained true to itself as a narrow textiles manufacturer. This testifies to the willingness of the people in the company to change and to their curiosity. Successful transformation is a joint development, there is an opportunity in change. vombaur has proven this many times over the past almost 220 years: We have adapted our product portfolio to new times, we have built new factory buildings and new machinery, we have introduced new materials and developed new technologies, we have entered into new partnerships – as most recently as part of the Textation Group. We are currently planning our new headquarters. We are not reinventing ourselves, but we will go through a kind of transformation process with the move into the brand new, climate-friendly high-tech space.

 

Could you describe the challenges of this transformation process?
 
Johannes Kauschinger, Sales Manager for Composites and Industrial Textiles: A transformation usually takes place technically, professionally, organisationally and not least – perhaps even first and foremost – culturally. The technical challenges are obvious. Secondly, in order to manage and use the new technologies, appropriate expertise is needed in the company. Thirdly, every transformation entails new processes, teams and procedures have to be adapted. And finally, fourthly, the corporate culture also changes. Technology can be procured, expertise acquired, the organisation adapted. Time, on the other hand, cannot be bought. I therefore consider the greatest challenge to be the supply of human resources: In order to actively shape the transformation and not be driven by development, we need sufficient skilled workers.

 

Visiting your website, the claim "pioneering tech tex" immediately catches the eye. Why do you see your company as a pioneer, and what are vombaur's groundbreaking or pioneering innovations?

Carl Mrusek: With our unique machine park, we are pioneers for seamless circular woven textiles. And as a development partner, we break new ground with every order. We are always implementing new project-specific changes: to the end products, to the product properties, to the machines. It happens regularly that we adapt a weaving machine for a special seamless woven shaped textile, sometimes even develop a completely new one.
 
With our young, first-class and growing team for Development and Innovation led by Dr. Sven Schöfer, we repeatedly live up to our promise of "pioneering tech tex" by developing special textile high-tech solutions with and for our customers. At the same time, we actively explore new potentials. Most recently with sustainable materials for lightweight construction and research into novel special filtration solutions, for example for the filtration of microplastics. A state-of-the-art textile technology laboratory is planned for this team in the new building.

 

The development of technical textiles in Germany is a success story. From a global perspective, we manage to succeed with mass-produced goods only in exceptional cases. How do you assess the importance of technical textiles made in Germany for the success of other, especially highly technological industries?

Carl Mrusek: We see the future of industry in Europe in individually developed high-tech products. vombaur stands for high-quality, reliable and durable products and made-to-order products. And it is precisely this – custom-fit products, instead of surplus and throwaway goods – that is the future for sustainable business in general.

 

What proportion of your production is generated by being project-based as opposed to a standard range, and to what extent do you still feel comfortable with the term "textile producer"?

Johannes Kauschinger: Our share of special solutions amounts to almost 90 percent. We develop technical textile solutions for our customers' current projects. For this purpose, we are in close contact with the colleagues from our customers' product development departments. Especially in the field of composite textiles, special solutions are in demand. This can be a component for space travel – after all, a spaceship is not manufactured off the peg. We also offer high-quality mass-produced articles, for example in the area of industrial textiles, where we offer round woven tubulars for conveyor belts. In this sense, we are a textile producer, but more than that: we are also a textile developer.

 

In August, Composites Germany presented the results of its 21st market survey. The current business situation is viewed very critically, the investment climate is becoming gloomier and future expectations are turning negative. vombaur also has high-strength textile composites made of carbon, aramid, glass and hybrids in its portfolio. Do you share the assessment of the economic situation as reflected in the survey?

Carl Mrusek: We foresee a very positive development for vombaur because we develop in a very solution-oriented way and offer our customers genuine added value. This is because future technologies in particular require individual, reliable and lightweight components. This ranges from developments for the air taxi to wind turbines. Textiles are a predestined material for the future. The challenge here is also to offer sustainable and recyclable solutions with natural raw materials such as flax and recycled and recyclable plastics and effective separation technologies.

 

There is almost no company nowadays that does not use the current buzzwords such as climate neutrality, circular economy, energy efficiency and renewable energies. What is your company doing in these areas and how do you define the importance of these approaches for commercial success?

Carl Mrusek: vombaur pursues a comprehensive sustainability strategy. Based on the development of our mission statement, we are currently working on a sustainability declaration. Our responsibility for nature will be realised in a very concrete and measurable way through our new building with a green roof and solar system. In our product development, the high sustainability standards – our own and those of our customers – are already flowing into environmentally friendly and resource-saving products and into product developments for sustainable projects such as wind farms or filtration plants.

 

Keyword digitalisation: medium-sized businesses, to which vombaur belongs with its 85 employees, are often scolded for being too reluctant in this area. How would you respond to this accusation?

Johannes Kauschinger:

We often hear about the stack crisis at the present time. Based on this, we could speak of the stack transformation. We, the small and medium-sized enterprises, are transforming ourselves in a number of different dimensions at the same time: Digital transformation, climate neutrality, skilled labour market and population development, independence from the prevailing supply chains. We are capable of change and willing to change. Politics and administration could make it a bit easier for us in some aspects. Key words: transport infrastructure, approval times, energy prices. We do everything we can on our side of the field to ensure that small and medium-sized enterprises remain the driving economic force that they are.

 

 

How do you feel about the term shortage of skilled workers? Do you also take unconventional paths to find and retain talent and skilled workers in such a specialised industry? Or does the problem not arise?

Carl Mrusek: Of course, we are also experiencing a shortage of skilled workers, especially in the industrial sector. But the development was foreseeable. The topic played a major role in the decision to move together with our sister company JUMBO-Textil under the umbrella of the Textation Group. Recruiting and promoting young talent can be better mastered together – for example with cross-group campaigns and cooperations.

 

If you had to describe a central personal experience that has shaped your attitude towards the textile industry and its future, what would it be?

Johannes Kauschinger: A very good friend of my family pointed out to me that we live in an area with a very active textile industry, which at the same time has problems finding young talents. I visited two companies for an interview and already on the tour of each company, the interaction of people, machines and textiles up to the wearable end product was truly impressive. In addition, I was able to learn a profession with a very strong connection to everyday life. To this day, I am fascinated by the wide range of possible uses for textiles, especially in technical applications, and I have no regrets whatsoever about the decision I made back then.

Carl Mrusek: I came into contact with the world of textiles and fashion at a young age. I still remember the first time I went through the fully integrated textile production of a company in Nordhorn with my father Rolf Mrusek. Since then, the subject has never left me. Even before I started my studies, I had made a conscious decision to pursue a career in this industry and to this day I have never regretted it, on the contrary. The diversity of the special solutions developed in the Textation Group fascinates me again and again.

DITF: Newly developed concept for chemical protective suits

A newly developed concept for chemical protective suits is designed to make use more comfortable and safer for the user. New materials and an improved design increase wearer comfort. The integration of sensor technology enables the monitoring of vital functions.

In the event of hazards from chemical, biological or radioactive substances, chemical protective suits (CSA) protect people from physical contact. CSAs consist of breathing apparatus, head protection, carrying frames and the suit itself. This adds up to a weight of around 25 kg. The construction of a multi-coated fabric makes the CSA stiff and provides for considerable restrictions in freedom of movement. As a result, the emergency forces are exposed to significant physical stress. For this reason, the total deployment time when using a CSA is limited to 30 minutes.

CSAs consist of breathing apparatus, head protection, carrying frames and the suit itself. This adds up to a weight of around 25 kg. The construction of a multi-coated fabric makes the CSA stiff and provides for considerable restrictions in freedom of movement. As a result, the emergency forces are exposed to significant physical stress. For this reason, the total deployment time when using a CSA is limited to 30 minutes.

In a joint project with various companies, institutes and professional fire departments, work is currently underway to completely redesign both the textile material composite and the hard components and connecting elements between the two. The goal is a so-called "AgiCSA", which offers significantly more comfort for the emergency forces due to its lighter and more flexible construction. The DITF subproject focuses on the development of a more individually adaptable, body-hugging suit on the one hand, and on the integration of sensors that serve the online monitoring of important body functions of the emergency personnel on the other.

At the beginning of the project, the DITF received support from the Esslingen Fire Department. They provided a complete CSA that is used as standard today. This could be tested at the DITF for its wearing properties. The researchers in Denkendorf are investigating where there is a need for optimization to improve ergonomic wearing comfort.

The aim is to construct a chemical- and gas-tight suit that fits relatively closely to the body. It quickly became clear that it was necessary to move away from the previous concept of using woven fabrics as the basic textile material and think in terms of elastic knitted fabrics. In implementing this idea, the researchers were helped by recent developments in the field of knitted fabric technology in the form of spacer fabrics. By using spacer textiles, many of the requirements placed on the base substrate can be met very well.

Spacer textiles have a voluminous, elastic structure. From a wide range of usable fiber types and three-dimensional design features, a 3 mm thick spacer textile made of a polyester pile yarn and a flame-retardant fiber blend of aramid and viscose was selected for the new CSA. This textile is coated on both sides with fluorinated or butyl rubber. This gives the textile a barrier function that prevents the penetration of toxic liquids and gases. The coating is applied to the finished suit by a newly developed spraying process. The advantage of this process over the conventional coating process is that the desired elasticity of the suit is retained.

Another innovation is the integration of a diagonal zipper. This makes it easier to put on and take off the suit. Whereas this was previously only possible with the help of another person, the new suit can in principle be put on by the emergency responder alone. The new design is modeled on modern dry suits with diagonal, gas-tight zippers.
The new AgiSCA also features integrated sensors that allow the transmission and monitoring of the vital and environmental data of the emergency worker as well as their location via GPS data. These additional functions significantly enhance operational safety.

For the hard components, i.e. the helmet and the backpack for the compressed air supply, lightweight carbon fiber-reinforced composite materials from Wings and More GmbH & Co. KG are used.
The first demonstrators are available and are available to the project partners for testing purposes. The combination of current textile technology, lightweight construction concepts and IT integration in textiles has led to a comprehensive improvement of a high-tech product in this project.

Innovative sportswear: Swim and run without changing

Just in time for summer: The Swiss start-up Swijin is launching a new sportswear category with its SwimRunner – a sports bra together with matching bottoms that works as both swimwear and running gear and dries in no time. The innovative product was developed together with Empa researchers in an Innosuisse project. The SwimRunner can be tested this weekend at the Zurich City Triathlon.
 
A quick dip after jogging without having to change clothes? Swijin (pronounced Swie-Djin), a new Swiss TechTex start-up, is launching its first product, the SwimRunner: a sports bra and bottoms that function as both swimwear and running gear and dry in a flash.

A quick dip after jogging without having to change clothes? Swijin (pronounced Swie-Djin), a new Swiss TechTex start-up, is launching its first product, the SwimRunner: a sports bra and bottoms that function as both swimwear and running gear and dry in a flash.

For the first time, this innovation enables women to make a smooth transition between land and water sports without having to change clothes. For example, hikers and runners can easily go into the water to cool off. Stand-up paddlers wearing the SwimRunner enjoy unrestricted freedom of movement and at the same time sufficient support, both on the board and in the water.
Science to boost sports performance
 
What appears to be a relatively simple requirement at first glance has turned out to be an extremely complex product to develop. As part of an Innosuisse project, Swijin collaborated with the Empa Biomimetic Membranes and Textiles laboratory in St. Gallen. Led by Empa engineer Martin Camenzind, the researchers first defined the requirements for the material and cut of the sports bra. "During development, we faced three main challenges: On the one hand, the product had to meet the requirements of a heavy-duty sports bra on land. At the same time, it had to maintain the compression of a swimsuit in the water – and do so with a very short drying time," says Camenzind.

Since no comparable garment exists on the market yet, the team also developed new tests for evaluating the high-performance textile. "Moreover, we designed a mannequin: a model of the female torso that can be used to measure the mechanical properties of bras," explains the researcher. In addition to scientific findings, the product development process also incorporated a great deal of expertise from sports physiologists, textile engineers, industry specialists, designers and, of course, female athletes.

Highest demands
Many of these athletes come from the swimrun scene. Swimrun is a fast-growing adventure sport that originated in the skerry gardens of Sweden. Unlike triathletes, who start out by swimming, then bike, and finally run, swimrunners switch back and forth between trail running and open water swimming throughout the race. The intensity of this sport provided Swijin with the optimal conditions for product development – and gave its name to the first collection, SwimRunner. "The feedback from female athletes was one of the deciding factors for the success of the product. They often swim and run for six to seven hours at a stretch. When they were satisfied with our prototypes, we knew: The SwimRunner is ready for market," says Swijin founder Claudia Glass.

The product idea first came to Claudia Glass while she was on vacation on Mallorca. During her morning runs, she longed to be able to take a quick dip in the sea. "Sports bras, however, are not designed for swimming," the founder explains. "They soak up the water and never seem to dry because of their thick compression material. Last summer, I wore the SwimRunner prototype all day. In the morning, I ran to Lake Zurich with my dog and jumped in. When I got back home, I could have just sat down at my desk and started working – I was completely dry and felt very comfortable."

Design and sustainability
The young company makes a point of combining engineering and design. Swijin's creative director, Valeria Cereda, is based in the center of the world's fashion capital, Milan, and infuses her experience with luxury brands into Swijin's aesthetic. But as a former competitive swimmer, she is also focused on functionality.

Swijin's high-performance products can only be realized with synthetic materials. The young company is determined to reduce the environmental impact of its products to a minimum. The tight supply chain keeps the CO2 footprint low. The materials of the SwimRunner are 100% made in the EU and designed for quality.

Traditional garment labels only provide information about where the garment was made. Swijin is working with supplier Avery Dennison to provide all products with a Digital Identity Label. This gives consumers detailed information about the entire value chain, right down to the textile manufacturer's investment in reducing its carbon footprint and the use of the water-based, solvent-free logo. Swijin packages all materials in Cradle-to-Cradle Gold certified packaging, which is produced by Voegeli AG in Emmental.

Furthermore, Swijin proactively addresses the challenges at the end of the product life cycle. In order to come one step closer to a truly circular economy for functional textiles, Swijin participates in the Yarn-to-Yarn® pilot project of Rheiazymes AG as a lighthouse partner. This biotech solution uses microorganisms and enzymes to generate new starting materials directly from used textiles in a climate-neutral way. When customers return end-of-life Swijin products – for which the company offers incentives – the high-quality monomers can be returned to the supply chain in their original quality: true circularity.

"As an emerging brand, we have both the obligation and the luxury of choosing partners whose vision and values align with our own," says Claudia Glass. "I had a clear understanding of what kind of brand I would buy, but I couldn't find it anywhere. With Swijin, we feel obligated to actually make our values a reality."

Prior to the conference, the conference advisory board had nominated six remarkable innovations. The winners were elected in an exciting head-to-head live-voting by the conference audience on the first day of the event.

The collaboration between Nanollose (AU) and Birla Cellulose (IN) with tree-free lyocell from bacterial cellulose called Nullarbor™ is the winning cellulose fibre innovation 2023, followed by Renewcell (SE) cellulose fibres made from 100 % textile waste, while Vybrana – the new generation banana fibre from Gencrest Bio Products (IN) won third place.
    
Winner: Nullarbor™ – Nanollose and Birla Cellulose (AU/IN)
In 2020, Nanollose and Birla Cellulose started a journey to develop and commercialize treefree lyocell from bacterial cellulose, called Nullarbor™. The name derives from the Latin “nulla arbor” which means “no trees”. Initial lab research at both ends led to the joint patent application “production of high-tenacity lyocell fibres made from bacterial cellulose”.
Nullarbor is significantly stronger than lyocell made from wood-based pulp; even adding small amounts of bacterial cellulose to wood pulp increases the fibre toughness. In 2022, the first pilot batch of 260 kg was produced with 20 % bacterial pulp share. Several high-quality fabrics and garments were produced with this fibre. The collaboration between Nanollose and Birla Cellulose now focuses on increasing the production scale and amount of bacterial pulp in the fibre.  

Second place: Circulose® – makes fashion circular – Renewcell (SE)
Circulose® made by Renewcell is a branded dissolving pulp made from 100 % textile waste, like worn-out clothes and production scraps. It provides a unique material for fashion that is 100 % recycled, recyclable, biodegradable, and of virgin-equivalent quality. It is used by fibre producers to make staple fibre or filaments like viscose, lyocell, modal, acetate or other types of man-made cellulosic fibres. In 2022, Renewcell, opened the world’s first textile-to-textile     
chemical recycling plant in Sundsvall, Sweden – Renewcell 1. The plant is expected to reach an annual capacity of 120,000 tonnes.

Third place: Vybrana – The new generation banana fibre – Gencrest Bio Products (IN)
Vybrana is a Gencrest’s Sustainable Cellulosic Fibre upcycled from agrowaste. Raw fibres are extracted from the banana stem at the end of the plant lifecycle. The biomass waste is then treated by the Gencrest patented Fiberzyme technology. Here, cocktail enzyme formulations remove the high lignin content and other impurities and help fibre fibrillation. The company's proprietary cottonisation process provides fine, spinnable cellulose staple fibres suitable for blending with other staple fibres and can be spun on any conventional spinning systems giving yarns sustainable apparel. Vybrana is produced without the use of heavy chemicals and minimized water consumption and in a waste-free process where balance biomass is converted to bio stimulants Agrosatva and bio-based fertilizers and organic manure.

Aerogel: Frozen Smoke for Clothing and Work Safety

Comprised of up to 99.8 percent air, aerogel is the lightest solid in the world. The material, which is also called “frozen smoke” due to its appearance and physical properties, exhibits extremely low heat conductivity which exceeds other insulations many times over. This is why NASA has already been using aerogel for aerospace projects for many years.

Despite this, it has not been possible to bind the material to textiles in a high concentration and enable straightforward further processing over the roughly 90-year history of the material. Outlast Technologies GmbH has developed an innovative process - a patent has already been filed for -  for permanently adhering large amounts of aerogel to different media, like nonwoven fabric, felt and composites materials. Their original properties are retained throughout, so they can easily be further processed using conventional production methods.

Outlast Technologies GmbH has developed an innovative process - a patent has already been filed for -  for permanently adhering large amounts of aerogel to different media, like nonwoven fabric, felt and composites materials. Their original properties are retained throughout, so they can easily be further processed using conventional production methods.

The fabrics sold under the Aersulate name are only 1 to 3 mm thick and achieve very high insulation values which are largely retained even under pressure and in moist conditions. Despite their high performance, they are still soft and can be used for shoes, clothing and work safety products, as well as for sleeping bags and technical applications.
 
“Thanks to its extraordinary physical properties, NASA has already been using aerogel for many years,” remarked Volker Schuster, Head of Research and Development at Outlast Technologies. “For example, for the insulation of its Mars rovers and for capturing dust from the tail of a comet during the Stardust mission,” he continued. Since the development of aerogel by American scientist and chemical engineer Samuel Stephens Kistler in 1931, no-one had been able to apply the versatile material to textiles in large amounts without changing their original properties, despite intensive research. This means that the products were often not only very rigid, but made processing with conventional production methods impossible due to their high degree of dust abrasion. With the newly developed Aersulate technology, which was presented for the first time in June 2022, the Heidenheim-based specialist for textile thermoregulation is opening a different chapter in insulation history.

High-performance insulation just 1 to 3 mm thick
“The consistency of aerogel can be best described as liquid dust particles which spread uncontrollably throughout a room within seconds thanks to their minimal thickness,” explained Schuster. “This is why processing is a big challenge.” Outlast Technologies has managed, after a development period of around five years, to bring an innovative process involving the adhering of aerogel between multiple layers of material to market maturity. Depending on the area of application, nonwoven fabric, felt and different composite materials can be used as the media. What is special here is that the properties of the respective textiles are not adversely affected by the Aersulate technology, meaning that they can easily be further processed with conventional means and under industrial conditions despite their acquired thermal properties.
 
As a silicate-based solid, aerogel is obtained from natural quartz sand, yet exhibits a density over 1,000 times lower than glass manufactured from the same raw material. The extraordinary thermo-insulating properties of the material are thanks to its extremely porous structure, which enables it to be composed of up to 99.8 percent air.
 
“One liter of aerogel weighs just 50 g,” explained Schuster. “Just 10 g of the material has the same surface area as a soccer field, though.” Thanks to these properties, Aersulate textiles exceed all other previously known insulation materials in terms of performance, despite the fact that they are only 1 to 3 mm thick. Tests carried out by the German Institute for Textile and Fiber Research in Denkendorf (DITF) using the Alambeta method showed that the thermal resistance of an Aersulate fleece is more than double that of a conventional fleece of the same thickness. Add to this the fact that the thermo-insulating properties of Aersulate products remain high despite pressure and wetness, while they decrease enormously with other conventional materials like felt and polyurethane foam (PU) under these conditions.

Work safety and functional clothing with Aersulate
Thanks to the textile medium, thin Aersulate products are especially suitable for the shoe and clothing industry, as well as all areas of work safety. The user benefits from different properties, depending on the intended use. “With a glove made of Aersulate just 1 mm thick, you can put your hand into boiling water without being scalded, for example,” explained Schuster. “The material’s extremely hydrophobic properties play quite literally into our hands here.” In the case of knee patches on work and functional pants, as well as shoes and soles, on the other hand, the material properties also become relevant when compression occurs. This is because the thermo-insulation properties of other materials would be reduced little by little due to moisture from the outside and sweat from the inside on the one hand, and by the continual influence of body weight on the other.
          
In addition to the human body, luggage and technical devices can also be protected from extreme temperatures and the effects of weather with Aersulate. For this purpose, corresponding cell phone or equipment pockets could be sewn into garments, for example, to maintain their battery life even at very cold outside temperatures and to safeguard the devices from overheating in case of high heat exposure. “With the broad range of possible textile medium materials, Aersulate is suitable for all applications requiring high thermal resistance on the one hand, where only a little space is available and both compression and moisture can be expected on the other,” said Schuster in summary.

New 3D printing process for sustainable fiber composite components

Nature works often with fiber composites. The construction principles of nature require little material and energy and thus ensure the survival of animals and plant species. Examples include wood, plant stalks, chitinous shells, bones or tissues such as tendons and skin. Mussel shells or spider silk are also composite tissues. We can take advantage of these principles to design and manufacture bio-based, sustainable fiber reinforced composites, which are currently in high demand. Bio-based fiber reinforced composites consist of natural fibers or cellulose fibers embedded in a bio-based matrix. The bio-based components offer properties comparable to those of commonly used glass fiber composites. The German Institutes of Textile and Fiber Research (DITF), together with Arburg GmbH + Co KG, are developing an energy- and material-efficient 3D printing process for manufacturing of such lightweight bio-based fiber composites.

The German Institutes of Textile and Fiber Research (DITF), together with Arburg GmbH + Co KG, are developing an energy- and material-efficient 3D printing process for manufacturing of such lightweight bio-based fiber composites.

In fiber composites, which occur naturally, reinforcing fibers such as collagen or cellulose fibrils are embedded in a matrix of lignin, hemicellulose or collagen. The fiber strands align with the stress patterns. Tissues are formed mostly via solution-based physio-chemical processes that take place at ambient temperature. Similar to nature, new 3D printing processes with continuous fiber reinforcement also allow the deposition of fiber strands in the right place (topology optimization) and in the appropriate direction in accordance to the load. However, natural fibers such as cellulose fibers are sensitive to higher temperatures. Therefore, they cannot be processed in the commonly employed thermoplastic 3D printing process.

The result of the research work is 3D-printed fiber composite components consisting of cellulose continuous fibers embedded in a cellulose-based matrix. Newly developed 3D-printing process enables to manufacture the composites at ambient temperature. This means that - as in nature - the material and component can be produced simultaneously in a single operation at ambient temperature.

The cellulose fiber strand is first stabilized with a binder for processing in the printer. The specially designed print head transforms the binder into a matrix with which the cellulose continuous fibers are encased. Since the cellulose fibers and the matrix have similar chemical structures, the composite component is particularly stable. The mechanical properties, such as breaking strength, are exceptionally good. The solution-based and energy-efficient manufacturing method developed by the research team can also be used in other composite materials manufacturing processes. It is particularly suitable for processing temperature-sensitive materials that are in high demand, such as natural or cellulose fibers.

Textile Skin & Smart Sensors: Robo-Ray in Search of Munitions

Giant arsenals of unexploded ordinance are sitting on the ocean floor, lost in battle or dumped as waste. The risky job of detecting these underwater hazards is currently given to submarines specially fitted for the purpose. But even they cannot get to some of the tighter or harder to reach spots, forcing expert divers to go down and take over the often life-threatening work.

A German research consortium including Fraunhofer IZM is now using a submarine robot that is as nimble and mobile as a manta ray and equipped with innovative connected sensors on its fins to gather more information about its surroundings. It can measure water pressure so precisely that metal objects can be detected on the ocean floor, even if they are covered by sediment.

A German research consortium including Fraunhofer IZM is now using a submarine robot that is as nimble and mobile as a manta ray and equipped with innovative connected sensors on its fins to gather more information about its surroundings. It can measure water pressure so precisely that metal objects can be detected on the ocean floor, even if they are covered by sediment.

Unmanned underwater vehicles or UUVs have been in use for several years, but high-tech pioneers for reliable underwater communication and innovative bionics like EvoLogics GmbH have let themselves be inspired by marine life like manta rays and adapted their look and technical anatomy to the submarine world.

With the enormous “wingspan” of their fins, manta rays are known to cover vast distances, while their extremely flexible vertebrae means that they can make surprisingly sharp turns on their seemingly weightless journey through the sea. Their robotic cousins can be very agile as well, but they were not smart enough yet to replace the professional divers who had to scour the sea floor for hours, looking for lost ordinance from the First or Second World War or other hazardous metal waste before offshore wind farms could be built or intercontinental cables could be put down. Now, the new robo ray will make it possible to detect submarine hazards with a whole battery of sensors.

The “Bionic RoboSkin” project, supported by Germany’s Ministry of Education and Research, is working to give the manta-shaped UUVs a flexible bionic sensor skin to help them navigate their underwater world. The skin is made from a compound fabric that is fitted with sensor elements and water-resistant connectors to supply the sensors with power and transmit their data. Researchers from Fraunhofer IZM have taken on the challenge of developing these integrated sensor modules with which the UUVs can detect touch or the proximity of objects and virtually see and analyze their surroundings. The project consortium is headed by EvoLogics GmbH and includes other experts in the field from TITV Greiz, Sensorik Bayern GmbH, the diving specialists of BALTIC Taucherei- und Bergungsbetrieb Rostock GmbH, and GEO-DV GmbH, all with one mission: To create a new generation of robots that can support their human partners with a range of semi or fully automated services and functions.

Their capabilities will not be limited to the sea: The researchers are looking at a second use case for a land-based robot sensor platform, fittingly called “Badger” or “Dachs” in German. It will navigate by GPS and be fitted with ground penetrating radar to detect metal objects below ground or conduct other ground survey work in harder to reach places (including tunneling work).

Under the robotic manta ray’s deceptively lifelike shell lies intricate technology: A permeable and therefore pressure-neutral fabric skin is created and fitted with integrated microelectronics for touch, flow, motion, and position sensors. This textile skin is then pulled tight over the robotic fins, creating a soft robotics machine that can sense its surroundings. The team at Fraunhofer IZM is responsible for the electronics that make this possible: They developed sensor nodes suitable for submersible use that can collect and pre-process the sensor data. These nodes do not only have to be fit for purpose, they also need to be extremely miniaturized to fit underneath the thin fabric skin and integrate the necessary connectors. In active operations below the waterline, these sensors can track parameters like acceleration, pressure, or absorbency. The researchers also included LEDs in the circuit board design that let the robotic manta rays communicate with human divers, for instance to signal a turn.

All of these components and sensor packages are integrated by means of a highly miniaturized embedding method and protected from the cold and wet environment by a robust case. Despite this, the footprint of the embedded modules is amazingly small at 23 x 10.5 x 1.6 mm³, fitting a complete sensor package and microcontroller in something the size of a common door key. The case itself works as a conductor by creating the mechanical and electrical contact with the sensor skin itself. The researchers chose a modular two-part design from their original vision of the product: The embedding module combines the individual electronic components on a millimeter scale for exceptional integration; the module case acts as the mechanical interface with the skin and makes the system as robust as it has to be for its destined purpose. The coupling between module and case relies on a seemingly simple clipping action: Small pins on the connector surface on the skin and tiny hooks on the sensor module itself snap together to form an easily de- and attachable interface. The resulting system is modular to allow easy reconfiguration.

The researchers at Fraunhofer IZM will now subject their robotic manta ray to a series of tests with their project partners. The results and findings from the “Bionic RoboSkin” project will likely be of use for many other projects and contribute to more pressure-neutral and reliable packaging solutions for flexible, mobile, and smarter service robots.

The “Bionic RoboSkin” project is supported through the VDI/VDE-IT by the Ministry of Education and Research (funding code 16ES0914) as part of the federal government’s research and innovation campaign 2016 to 2020 “Microelectronics from Germany – Driver of Innovation for the Digital Economy”.

Sustainability in 3D Printing: Components made of Natural Fibers

3D printing has been in use in architecture for a while, and now it is to become ecologically sustainable as well: Together with partners, the LZH is researching how to produce individual building elements from natural fibers using additive manufacturing.

3D printing has been in use in architecture for a while, and now it is to become ecologically sustainable as well: Together with partners, the LZH is researching how to produce individual building elements from natural fibers using additive manufacturing.

In the project 3DNaturDruck, architectural components such as facade elements shall be created from natural fiber-reinforced biopolymers in 3D printing. To this end, the scientists will develop the corresponding composite materials from biopolymers with both natural short fibers and natural continuous fibers and optimize them for processing with the additive manufacturing process FDM (Fused Deposition Modeling). The project partners' goal is to enable smart and innovative designs that are both ecological and sustainable.
 
The goal: highly developed components made from sustainable materials
Within the project, different natural fiber-reinforced biopolymer composites will be investigated. The partners are researching both processing methods with very short natural fibers, such as from wood and straw, and a method for printing continuous fibers from hemp and flax in combination with biopolymers. The LZH then develops processes for these new materials and adapts the tools and nozzle geometries of the FDM printer. A pavilion with the 3D-printed facade elements is planned as a demonstrator on the campus of the University of Stuttgart.
 
The project partners want to explore how additive manufacturing can be used to simplify manufacturing processes for architectural components. Natural fiber-reinforced biopolymers are particularly suitable for producing components with complex geometries in just a few steps and with low material and cost requirements. With their research, the partners are also working on completely new starting conditions for the fabrication of newly developed architectural components: For example, the topology optimization of components according to their structural stress can be easily implemented with additive manufacturing.

Enabling the natural fiber trend in architecture also using additive manufacturing
There is great interest in the use of natural fibers in structural components in architecture and construction because natural fibers have several advantages. They have good mechanical properties combined with low weight and are widely available. As a renewable resource with in some cases very short renewal cycles, they are also clearly a better ecological alternative than synthetic fibers.

In additive manufacturing, large-format elements for the architectural sector have so far mostly been manufactured with polymers based on fossil raw materials. Research in the project 3DNaturDruck should now make the use of natural fibers in architecture possible for additive manufacturing as well.

About 3DNaturDruck
The project 3DNaturDruck is about the design and fabrication of 3D-printed components made of biocomposites using filaments with continuous and short natural fibers.

The project is coordinated by the Department of Biobased Materials and Materials Cycles in Architecture (BioMat) at the Institute of Building Structures and Structural Design (ITKE) at the University of Stuttgart. In addition to the LZH, project partners include the Fraunhofer Institute for Wood Research Wilhelm-Klauditz-Institut (WKI) and the industrial companies Rapid Prototyping Technologie GmbH (Gifhorn), ETS Extrusionstechnik (Mücheln), 3dk.berlin (Berlin) and ATMAT Sp. Z o.o. (Krakow, Poland).

The project is funded by the German Federal Ministry of Food and Agriculture through the Fachagentur Nachwachsende Rohstoffe e.V. under the funding code 2220NR295C.

ALTENPFLEGE 2022: Intelligently equipped rooms for more independence in old age

Most people want to live as independently as possible in old age. Exhibitors at the industry's leading trade fair ALTENPFLEGE from April 26 to 28 in Essen, Germany will be showing how senior facilities with modern interior design and smart equipment meet this need.

Demand for forms of housing such as service living is on the rise. Studies predict a need for around 540,000 new service living units in the coming years. One of the major trends at this year's 32nd edition of the Altenpflege trade fair is how senior facilities are meeting the rapidly growing demand with flexible room design and digital support. They can be seen in the Aveneo special show, including intelligent systems for stove shut-off, lighting control and room temperature, as well as for fall sensors and emergency calls.

Future tenants or buyers of serviced apartments are prepared to invest specifically in their own living environment (source: Terragon study 2021). The focus is on a feel-good atmosphere, a high level of security and the option of using care services if required. "This can be facilitated by a cleverly thought-out arrangement of the rooms within a serviced apartment, for example by arranging the bathroom and bedroom right next to each other and making the wall with the washbasin rotatable," explains Carolin Pauly, managing director of Universal Rooms, which considers itself to be the interface between the wishes of the operators and the products in the serviced apartment market. "The furniture and furnishings industry is called upon to design modern collections with hidden product features that make life easier in old age," Pauly demands. This could be, for example, a grab handle built into the washbasin or a dining table that can be accessed by a wheelchair.

Lighting management also plays an important role. It should convey a sense of well-being and security as well as provide orientation and safety. Age-related clinical pictures in particular place high demands on lighting. Here, lighting systems that simulate the natural day and night rhythm can provide help.

Living, care and digitalization combined
The Chief Executive Officer of the Evangelische Heimstiftung (EHS - Evangelical Home Foundation), Bernhard Schneider, sees "an individually and comfortably furnished apartment that uses intelligent technology to provide a great deal of security and self-determination" as the senior living of the future. "I am certain: In the future, in a sector-free setting, we will have to understand housing, nursing and care, and digitalization even more strongly as building blocks that can be combined as needed."

According to Schneider, this starts with housing: In a nursing apartment or an assisted living apartment, in a shared apartment or other form of communal living, in a residence or an intergenerational project. All forms of housing should be well integrated into the neighborhood - this requires reliable, financed advisory structures, for example through neighborhood managers. In addition, there is care, support and assistance, in the form of day or night care, a mobile service or volunteers. "And technology, for example through our Aladien system, i.e. with intelligent home emergency call, fall sensors, stove shut-off, roller shutters and light control, video door telephony, etc. In the future, Aladien will evolve into a service robot," predicts Schneider.

This makes it possible for people to live a self-determined life and participate in society, even in old age. That's what people want, he says: a pleasant living environment, social contacts, cultural offerings and the certainty that someone will take care of them if necessary. "What we need for this is political commitment in the form of an ambitious funding program for modern forms of housing in old age," demands the EHS CEO. This would not only help the older generation, but young families could also benefit because this would free up the far too spacious apartments and terraced houses of the older generation for them.


ALTENPFLEGE – Trade fair and congress for the care industry since 1990
The traditional leading trade show for the care industry has so far been held alternately in Hanover and Nuremberg. From this year it alternates between Essen and Nuremberg. It covers all segments of professional geriatric care: services and products for care and therapy, occupation and education, IT and management, nutrition and home economics, textiles and hygiene as well as space and technology. In more than 30 lecture blocks, the accompanying trade congress covers the current topics of the industry, such as digitalization, the future of professional nursing care, hospice and palliative care, training or the new collectively agreed payment under the Healthcare Development Act (Gesundheitsversorgungsweiterentwicklungsgesetz - GVWG).

  • Second hand replaces new: 84 percent have bought less new goods due to second hand shopping
  • 71 percent have spent less money on new goods because they have bought second-hand clothing
  • For just under one in two (45 percent), buying second-hand clothing has become a matter of course
  • When buying second-hand fashion, sustainable production is more important (60 percent) than the brand name (48 percent)

Second hand replaces new - that's what 84 percent of second hand shoppers in Germany say, stating that buying second hand items has replaced buying a new clothing item for them.

  • Representative study with almost 8,000 participants regarding the second hand fashion market in Germany
  • Second hand replaces new: 84 percent have bought less new goods due to second hand shopping
  • 71 percent have spent less money on new goods because they have bought second-hand clothing
  • For just under one in two (45 percent), buying second-hand clothing has become a matter of course
  • When buying second-hand fashion, sustainable production is more important (60 percent) than the brand name (48 percent)

Second hand replaces new - that's what 84 percent of second hand shoppers in Germany say, stating that buying second hand items has replaced buying a new clothing item for them. Another 71 percent state that they have spent less money on clothing because they have bought used items.** These are the results of the current Second Hand Fashion Report 2022, for which the second hand online store momox fashion has conducted two studies for the third time in a row: A representative survey in cooperation with the market research institute Kantar as well as a customer survey among momox fashion customers to get detailed insights into the second hand clothing market. A total of 7,826 people took part in the surveys.

Buying second hand clothes has become a matter of course for every second person
The representative Kantar survey shows that buying second-hand clothing has become routine: 67 percent of Germans have already bought second-hand clothing at some point - an increase of eleven percent on the previous year. More than one in two (56 percent) do so regularly - at least once a year. For 45 percent, buying second-hand clothing has become a matter of course or very much a matter of course. In addition, more than half of Germans (53 percent) estimate that their closet consists of up to 20 percent second-hand clothing.*

Second hand clothing is not only shopped online, but also sold
The most popular way to buy used clothing is online shopping: 44 percent of respondents buy their second-hand fashion pieces online. Around one in three (28 percent) go to second-hand stores in search of their next favorite second-hand item, followed by flea markets with 14 percent. Surprisingly, the 50+ generation in particular likes to buy online (44 percent). Generation Z (under 25s), however, prefers second-hand stores (30 percent).*

But it is not only second-hand online shopping that is popular. Almost one in two (45 percent) resells used clothing, preferably online (76 percent). Only 11 percent sell at flea markets and 8 percent at second-hand stores.*

Sustainability remains main motivation for buying used clothing
To find out more about the reasons for buying second-hand clothing, momox fashion conducted a customer survey among almost 7,000 participants. The main motivation for buying second-hand clothing continues to be the sustainability aspect with 87 percent. 83 percent buy second-hand clothing because of the price savings compared to new goods. Around one in two (49 percent) goes in search of clothing in second-hand stores because the desired items are no longer available in regular stores.**

Almost all respondents (91 percent) generally consider sustainability and environmental protection to be important or very important when buying clothing. This is also reflected in consumer behavior: Around three quarters (85 percent) try to buy second-hand whenever possible. 58 percent make sure to purchase sustainable clothing. And 31 percent use environmentally friendly products for the care and cleaning of clothing.**

Sustainable production or brand name - which is more important?
For more than half (51 percent) of the respondents, the brand name is less important or unimportant when buying used clothing. Whether the clothing was produced sustainably, on the other hand, is considered by 60 percent to be very important or important. Especially for the 60+ generation (75 percent), sustainable production of second-hand clothing is very important or important.**

Second hand clothing is especially popular among parents
However, second-hand clothing is not only bought for oneself, almost every fifth person (18 percent) also buys it for his/her children.* Among the parents of the second-hand shoppers, 85 percent buy second-hand clothing for their children. Online stores (58 percent) and online marketplaces and second-hand online stores (51 percent) are the most popular. 43 percent buy used children's clothing from friends. 33 percent like to go shopping in second-hand stores and another 23 percent in stationary children's clothing stores. At the same time, 63 percent of respondents say they buy more second-hand clothing since becoming parents.**

Jackets and coats are second hand top sellers
Second-hand jackets and coats (70 percent) are the most popular items, followed by sweaters (60 percent), dresses and skirts (56 percent) and pants (49 percent). Pants and sweaters seem to have become more popular among second-hand shoppers compared to the previous year (previous year: 46 percent and 51 percent). Younger shoppers (18-29 year olds) prefer to buy their sweaters second hand even more than jackets and coats (80 percent).**

FIMATEC innovation network enters second funding phase

The network for the development of fiber materials technology for healthcare and sports will receive funding from the Central Innovation Programme for SMEs (ZIM) for another two years.

The Federal Ministry for Economic Affairs and Climate Action (BMWi) approved a corresponding application in December 2021. This will continue to provide funding for the development of innovative functional fibers, smart textiles and application-optimized fiber composite materials until June 2023 and strengthen the technological competitiveness and innovative strength of small and medium-sized enterprises (SMEs).

The network for the development of fiber materials technology for healthcare and sports will receive funding from the Central Innovation Programme for SMEs (ZIM) for another two years.

The Federal Ministry for Economic Affairs and Climate Action (BMWi) approved a corresponding application in December 2021. This will continue to provide funding for the development of innovative functional fibers, smart textiles and application-optimized fiber composite materials until June 2023 and strengthen the technological competitiveness and innovative strength of small and medium-sized enterprises (SMEs).

For this purpose, the FIMATEC innovation network combines competences from different engineering and scientific disciplines with small and medium-sized manufacturers and service providers from the target sectors in medicine and sports (e.g. orthopaedics, prosthetics, surgery, smart textiles) as well as players from the textile and plastics industry.      

This interdisciplinary combination of industrial partners and application-oriented research institutions increases competitiveness and enables the players to realise their technical research and development projects quickly and in a targeted manner. The focus for the joint R&D projects of the companies and research institutions is on the development of innovative materials and efficient manufacturing technologies. 
          
Fiber-based materials have become indispensable in many applications in medicine and sports. As a pure fiber, processed into a textile or as a fiber composite plastic, they offer an almost unlimited variety for adjusting property and functional profiles. At the same time, the demands on the range of functions, performance and cost-effectiveness are constantly increasing, so that there is great potential for innovation. Developments are driven on the one hand by new materials and manufacturing processes, and on the other by innovative applications. Products with new and superior functions create a technological advantage over international competitors and enable higher sales revenues. In addition, efficient processes, application-optimized materials or even the integration of functions into the basic structure of textile materials lead to lower production costs and improved marketing opportunities in the future.
For developments in this context, the partners have joined forces in the FIMATEC innovation network, thus combining their expertise. Within the network, innovative materials and processes are being developed jointly in the following areas and tested in future-oriented products and services:

  • Functional fibers
    Innovative fiber materials with integrated functionalities
  • Preforming
    Highly load path optimized fiber orientations for complex fiber composite components.    
  • Smart Textiles
    Textile-based sensors and actuators
  • Hybrid material and manufacturing technologies
    Application-optimized components through cross-technology solution approaches.    
  • Fiber composites  
    Intelligent matrix systems and function-optimized fiber materials.    
  • Fiber-reinforced 3D printing  
    High-quality additive manufacturing processes for the efficient production of individualized products.

 
17 network partners are researching fiber-based materials for medical and sports technologyCurrently, ten companies and seven research institutions are involved in FIMATEC. Interested companies and research institutions as well as potential users can continue to participate in the cooperation network or R&D projects. In the course of membership, the partners are actively supported in identifying and initiating innovation projects as well as securing financing through funding acquisition. One application for ZIM project funding has already been approved by FIMATEC in its first year.

The aim of the already approved project "CFKadapt" is to develop a thermoformable fiber-plastic composite material for optimally adaptable orthopedic aids such as prostheses and orthoses. In the "Modul3Rad" project, which is currently being worked out in detail, the project partners intend to develop a modular lightweight frame system for the construction of user-friendly therapy tricycles, suitable for everyday use by severely and very severely disabled children. Three further collaborative projects are already in the planning stage.

The technology and knowledge transfer enables in particular small and medium-sized enterprises (SMEs) to access cutting-edge technological research, especially these are often denied access to innovations due to the lack of their own research departments. The IWS GmbH has taken over the network management for FIMATEC and supports the partners from the first idea to the search for suitable project partners and the preparation and coordination of funding applications. The aim is to obtain funding from the Central Innovation Programme for SMEs (ZIM), which offers companies funding opportunities for a wide range of technical innovation projects in cooperation with research institutions.

Funding Project Raw Material Classification of Recycled Fibers

For centuries, old textiles have been used to make tear fibers and processed into new textile products. This effective recycling is one of the oldest material cycles in the world. Today, it is not only clothing that is recycled, but also high-quality technical textiles. As the products of the textile industry evolve, so do the demands on textile recycling. The basis for this is a clear assessment and classification of raw materials.

For centuries, old textiles have been used to make tear fibers and processed into new textile products. This effective recycling is one of the oldest material cycles in the world. Today, it is not only clothing that is recycled, but also high-quality technical textiles. As the products of the textile industry evolve, so do the demands on textile recycling. The basis for this is a clear assessment and classification of raw materials.

In the research project of the German Institutes of Textile and Fiber Research Denkendorf (DITF) and the Sächsisches Textilforschungsinstitut e.V. (STFI - Saxony Textile Research Institute), a methodology is being developed that will make it possible to analyze the tearing as well as the subsequent processes with regard to fiber quality. The systematic analysis should make it possible to optimize the subsequent spinning processes in such a way that the recycled content of the yarn can be increased without the yarn properties differing significantly from those of a yarn consisting of 100% good fibers. These yarns can then be processed into sustainable textile products such as clothing or composite components.

The project, which is funded by the BMWi/IGF, is scheduled to run for two years and will end on December 31, 2022. The main benefits for the participating companies are to enable them to make greater use of secondary raw materials, to open up new markets through technologies or products developed in the project, to initiate synergies and long-term cooperation, and to prepare a joint market presence.    

The project includes several steps:

  • Material selection and procurement
    Cotton fibers to be processed are obtained from used textiles (T-shirts) and waste from the cotton spinning mill. Aramid fibers are processed from used protective clothing and technical textiles.
  • Optimization of the preparation / dissolution of the textiles
    To ensure that the fibers are detached from the corresponding textiles as gently as possible and with a not too high reduction, exact settings have to be found for the tearing process, which are technologically very demanding and require a lot of experience.
  • Determination of the quality criteria for the evaluation of the fiber dissolution
    In order to define the quality criteria, the fibers coming from the tearing mill are determined by means of an MDTA-4 measuring device from Textechno GmbH & Co. KG. The criteria determined are to be used to characterize the (lowest possible) fiber shortening caused by the tearing process.
  • Determination of optimized settings in the spinning process
    In order to determine the optimum settings for producing a yarn from the recycled fibers, they are spun after the rotor spinning process. By adjusting the spinning process, the aim is to produce a yarn that has good uniformity and also appropriate firmness.
  • Production and comparison of yarns from recycled raw materials
    In order that the recycled fibers - consisting of aramid and cotton - can each be used to produce an area-measured material, the material is to be processed at industrial scale. For this purpose, the fibers are processed over a complete blowroom line with following sliver production over adapted cards. After drawing and the following roving production, yarns are produced according to the rotor or ring spinning process. The finished yarns are used to produce knitted fabrics.
  • Coordination, analysis of results and preparation of reports
    The final report is prepared by the DITF and the STFI. The results will be transferred through publications, technical information to associations and trade fair presentations. Regular meetings with the participating companies are planned.

Textination spoke with Stephan Baz, Deputy Head of the Competence Center Staple Fiber, Weaving & Simulation, Head of Staple Fiber Technology and Markus Baumann, Research Associate at the Competence Center Staple Fiber, Weaving & Simulation (both DITF) as well as Bernd Gulich, Head of Department Nonwovens/Recycling and Johannes Leis, Research Associate Focus Nonwovens/Recycling (both STFI) about the current status of the funding project.

What is the current status of the project?
We are currently in the phase of carrying out trials and the iterative optimization of several project components. As expected, several loops are necessary for the mechanical preparation itself and also for the adjustment of the spinning process with the different variants. Ultimately, after all, the project aims at coordinating the processes of mechanical preparation and spinning as processing in order to achieve optimum results. At the same time, determining the quality criteria of the fibers produced is not trivial. This also requires the further development of processes and test methods that can be implemented productively in industry and that allow the quality of the fibers produced to be assessed effectively and unaffected by residual yarns, for example. What is really remarkable is the interest and willingness of the industry to drive the project work forward. The considerable quantities of materials required for our trials were purchased from ReSales Textilhandel und -recycling GmbH, Altex Textil-Recycling GmbH & Co. KG and Gebrüder Otto GmbH & Co. KG. Furthermore, with Temafa Maschinenfabrik GmbH, Nomaco GmbH & Co. KG, Schill + Seilacher GmbH, Spinnerei Neuhof GmbH & Co. KG and Maschinenfabrik Rieter AG, many members of the project-supporting committee are actively involved in the project, from consulting to the providing of technologies. The company Textechno Herbert Stein GmbH & Co. KG has provided a testing device of the type MDTA4 for the duration of the project and supports our work with regard to the evaluation of the mechanically prepared fibers. We are of course particularly pleased about this, as it has allowed us to look at and analyze several technologies in both mechanical preparation, testing and spinning. We expect to be able to make more detailed statements at the beginning of the coming year.

Which approaches do you think are particularly promising?
With regard to technologies, we must refer to the evaluation and analysis of the trials, which are currently still ongoing. We will be able to go into more detail in the first quarter of next year.

Of course, things are already emerging. With meta-aramid waste, promising approaches could be found very quickly; with post-consumer cotton, this is considerably more complex. Obviously, there is a link between the quality of the raw material and the quality of the products. In some cases, we have already been able to determine very low average fiber lengths in the procured goods; to a certain extent, these are of course directly reflected in the output of our processes. From this, and this is not a new finding, a great importance of the design of the textiles is again derived.

What are the challenges?
In addition to the expected high short fiber content, the residual yarns after the tearing process are an issue of particular focus. The proportion of these residual yarns can vary between the materials and preparation technologies, but the further dissolution of the products of the tearing process is essential.

If the processes are considered further in a utilization phase, the question of design naturally also arises for the best possible use of recycled fibers. Many problems, but also the approaches to solutions for the use of comparatively short fibers, can also be expected to apply to the (multiple) use of mechanically recycled fibers.

Can we speak of upcycling in the final product?
We see yarn-to-yarn recycling neither as upcycling nor downcycling, but as closed-loop recycling. The background is that the products are to go into the same application from which they came and have to compete with primary material. This means that certain specific requirements have to be met and at the same time there is considerable price pressure. In the case of downcycling, a significant reduction in properties is accepted, while in the case of upcycling, the higher-priced application can make up for the reprocessing effort. In the attempt to produce yarn material again from yarn material, both are only permissible to a small extent. This represents the particular challenge.

What does a recyclate prepared from used textiles mean for the spinning process?
Part of this question is to be answered in the project by the detailed classification of the processed fibers and is thus the subject of the tests currently underway. It turns out that, in addition to the rather obvious points such as significantly reduced fiber length, process disturbances due to undissolved fabrics and yarn pieces, there are also less obvious aspects to be considered, such as a significantly increased outgoing quantity for processing in the spinning process. The outgoing quantity is of particular interest here, because in the end the newly produced yarn should also contain a considerable proportion of prepared fibers.

What consequences does this have for textile machinery manufacturing?
The consequences that can already be estimated at the present time are that, particularly in the processing of cotton, the machinery in the spinning preparatory mill is specialized in the processing of (new) natural fibers with a certain amount of dirt. In contrast to new fibers, processed fibers are clean fibers with a significantly higher proportion of short fibers. Elements that are good at removing dirt also reject an increased amount of short fibers, which can lead to unintentionally high waste quantities under certain circumstances. It is therefore necessary to adapt the established machine technology to the new requirement profile of the raw material "processed fibers". Analogous adaptations are probably necessary along the entire processing chain up to the yarn. In the drafting system of the spinning machine, of course, this is due more to the high short fiber ratio than to elements that have been optimized for cleaning out dirt and foreign substances.

Toray Industries: A Concept to change Lives

Founded in January 1926, Tokyo-based Japanese chemical company Toray Industries, Inc. is known as the world's largest producer of PAN (polyacrylonitrile)-based carbon fibers. But its overall portfolio includes much more. Textination spoke with Koji Sasaki, General Manager of the Textile Division of Toray Industries, Inc. about innovative product solutions, new responsibilities and the special role of chemical companies in today's world.

Toray Industries is a Japanese company that - originating in 1926 as a producer of viscose yarns - is on the home stretch to its 100th birthday. Today, the Toray Group includes 102 Japanese companies and 180 overseas. They operate in 29 countries. What is the current significance of the fibers and textiles business unit for the success of your company?

But its overall portfolio includes much more.

Toray Industries is a Japanese company that - originating in 1926 as a producer of viscose yarns - is on the home stretch to its 100th birthday. Today, the Toray Group includes 102 Japanese companies and 180 overseas. They operate in 29 countries. What is the current significance of the fibers and textiles business unit for the success of your company?

The fibers’ and textiles’ business is both the starting point and the foundation of Toray's business development today. We started producing viscose yarns in 1926 and conducted our own research and development in nylon fibers as early as 1940. And since new materials usually require new processing methods, Toray also began investing in its own process technology at an early stage. On the one hand, we want to increase our sales, and on the other hand, we want to expand the application possibilities for our materials. For this reason, Toray also began to expand its business from pure fibers to textiles and even clothing. This allows us to better respond to our customers' needs while staying at the forefront of innovation.

Over the decades, Toray has accumulated a great deal of knowledge in polymer chemistry and organic synthesis chemistry - and this know-how is the foundation for almost all of our other business ventures. Today, we produce a wide range of advanced materials and high-value-added products in plastics, chemicals, foils, carbon fiber composites, electronics and information materials, pharmaceuticals, medicine and water treatment. However, fibers and textiles remain our most important business area, accounting for around 40% of the company's sales.

What understanding, what heritage is still important to you today? And how do you live out a corporate philosophy in the textile sector that you formulate as "Contributing to society through the creation of new value with innovative ideas, technologies and products"?

Toray has consistently developed new materials that the world has never seen before. We do this by focusing on our four core technologies: Polymer chemistry, organic synthetic chemistry, biotechnology and nanotechnology. We do this by focusing on our four core technologies: Polymer chemistry, organic synthetic chemistry, biotechnology and nanotechnology. For textiles, this means we use new polymer structures, spinning technologies and processing methods to develop yarns with unprecedented properties. We always focus on the needs and problems of the market and our customers.

This approach enables us to integrate textiles with new functions into our everyday lives that natural fibers and materials cannot accomplish. For example, we offer sportswear and underwear that absorb water excellently and dry very quickly, or rainwear and outdoor clothing with excellent water-repellent properties that feature a less bulky inner lining. Other examples include antibacterial underwear, uniforms, or inner linings that provide a hygienic environment and reduce the growth of odor-causing bacteria. People enjoy the convenience of these innovative textiles every day, and we hope to contribute to their daily comfort and improve their lives in some way.

In 2015, the United Nations adopted 17 sustainable development goals – simply known as the 2030 Agenda, which came into force on January 01, 2016. Countries were given 15 years to achieve them by 2030. In your company, there is a TORAY VISION 2030 and a TORAY SUSTAINABILITY VISION. How do you apply these principles and goals to the textile business? What role does sustainability play for this business area?

Sustainability is one of the most important issues facing the world today - not only in the textile sector, but in all industries. We in the Toray Group are convinced that we can contribute to solving various problems in this regard with our advanced materials. At the same time, the trend towards sustainability offers interesting new business approaches. In our sustainability vision, we have set four goals that the world should achieve by 2050. And we have defined which problems need to be addressed to achieve this.

We must:

  1. accelerate measures to combat climate change,
  2. implement sustainable, recycling-oriented solutions in the use of resources and in production,
  3. provide clean water and air, and
  4. contribute to better healthcare and hygiene for people around the world.

We will drive this agenda forward by promoting and expanding the use of materials that respond to environmental issues. In the textile sector, for example, we offer warming and cooling textiles – by eliminating the need for air conditioning or heating in certain situations, they can help reduce energy costs. We also produce environmentally friendly textiles that do not contain certain harmful substances such as fluorine, as well as textiles made from biomass, which use plant-based fibers instead of conventional petrochemical materials. Our product range also includes recycled materials that reduce waste and promote effective use of resources.

The TORAY VISION 2030, on the other hand, is our medium-term strategic plan and looks at the issue of sustainability from a different angle: Toray has defined the path to sustainable and healthy corporate growth in it. In this plan, we are focusing on two major growth areas: Our Green Innovation Business, which aims to solve environmental, resource and energy problems, and the Life Innovation Business, which focuses on improving medical care, public health, personal safety and ultimately a longer expectancy of life.

Innovation by Chemistry is the claim of the Toray Group. In a world where REACH and Fridays for Future severely restrict the scope of the chemical industry, the question arises as to what position chemistry can have in the textile industry. How do chemistry, innovation and sustainability fit together here?

The chemical industry is at a turning point today. The benefits that this industry can bring to civilization are still enormous, but at the same time, disadvantages such as the waste of resources and the negative impact on the environment and ecosystems are becoming increasingly apparent. In the future, the chemical industry will have to work much more towards sustainability - there is no way around it.

As far as textiles are concerned, we believe there are several ways to make synthetic materials more sustainable in the future. One of these, as I said, is materials made from plants instead of petrochemical raw materials. Another is to reduce the amount of raw materials used in production in the first place – this can be achieved, for example, by collecting and recycling waste materials from production or sales. Biodegradable materials that reduce the impact of waste products on the environment are another option worth pursuing, as is the reduction of environmentally harmful substances used in the production process. We are already looking at all of these possibilities in Toray's synthetic textiles business. At the same time, by the way, we make sure to save energy in our own production and minimize the impact on the environment.

Toray's fibers & textiles segment focuses on synthetic fibers such as nylon, polyester and acrylic, as well as other functional fibers. In recent years, there has been a clear trend on the market towards cellulosic fibers, which are also being traded as alternatives to synthetic products. How do you see this development – on the one hand for the Toray company, and on the other hand under the aspect of sustainability, which the cellulosic competitors claim for themselves with the renewable raw material base?

Natural fibers, including cellulose fibers and wool, are environmentally friendly in that they can be easily recycled and are rapidly biodegradable after disposal. However, to truly assess their environmental impact, a number of other factors must also be considered: Primarily, there is the issue of durability: precisely because natural fibers are natural, it is difficult to respond to a rapid increase in demand, and quality is not always stable due to weather and other factors.

Climatic changes such as extreme heat, drought, wind, floods and damages from freezing can affect the quantity and quality of the production of natural fibers, so that the supply is not always secured. In order to increase production, not only does land have to be cleared, but also large amounts of water and pesticides have to be used to cultivate it – all of which is harmful to the environment.

Synthetic fibers, on the other hand, are industrial products manufactured in controlled factory environments. This makes it easier to manage fluctuations in production volume and ensure consistent quality. In addition, certain functional properties such as resilience, water absorption, quick drying and antibacterial properties can be embedded into the material, which can result in textiles lasting longer in use.

So synthetic fibers and natural fibers, including cellulose fibers, have their own advantages and disadvantages – there is no panacea here, at least not at the moment. We believe: It is important to ensure that there are options that match the consumer's awareness and lifestyle. This includes comfort in everyday life and sustainability at the same time.

To what extent has the demand for recycled products increased? Under the brand name &+™, Toray offers a fiber made from recycled PET bottles. Especially with the "raw material base: PET bottles", problems can occur with the whiteness of the fiber. What distinguishes your process from that of other companies and to what extent can you compete with new fibers in terms of quality?

During the production of the "&+" fiber, the collected PET bottles are freed from all foreign substances using special washing and filtering processes. These processes have not only allowed us to solve the problem of fiber whiteness – by using filtered, high-purity recycled polyester chips, we can also produce very fine fibers and fibers with unique cross sections. Our proven process technologies can also be used to incorporate specific textures and functions of Toray into the fiber. In addition, "&+" contains a special substance in the polyester that allows the material to be traced back to the recycled PET bottle fibers used in it.

We believe that this combination of aesthetics, sustainability and functionality makes the recycled polyester fiber "&+" more competitive than those of other companies. And indeed, we have noticed that the number of requests is steadily increasing as companies develop a greater awareness of sustainability as early as the product planning stage.

How is innovation management practiced in Toray's textile division, and which developments that Toray has worked on recently are you particularly proud of?

The textile division consists of three sub-divisions focusing on the development and sale of fashion textiles (WOMEN'S & MEN'S WEAR FABRICS DEPT.), sports and outdoor textiles (SPORTS WEAR & CLOTHING MATERIALS FABRICS DEPT.) and, specifically for Japan, textiles for uniforms used in schools, businesses and the public sector (UNIFORM & ADVANCED TEXTILES DEPT.).

In the past, each division developed its own materials for their respective markets and customers. However, in 2021, we established a collaborative space to increase synergy and share information about textiles developed in different areas with the entire department. In this way, salespeople can also offer their customers materials developed in other departments and get ideas for developing new textiles themselves.

I believe that the new structure will also help us to respond better to changes in the market. We see, for example, that the boundaries between workwear and outdoor are blurring – brands like Engelbert Strauss are a good example of this trend. Another development that we believe will accelerate after the Corona pandemic is the focus on green technologies and materials. This applies to all textile sectors, and we need to work more closely together to be at the forefront of this.

How important are bio-based polyesters in your research projects? How do you assess the future importance of such alternatives?

I believe that these materials will play a major role in the coming years. Polyester is made from purified terephthalic acid (PTA), which again consists of paraxylene (PX) and ethylene glycol (EG). In a first step, we already offer a material called ECODEAR™, which uses sugar cane molasses waste as a raw material for EG production.

About 30% of this at least partially bio polyester fiber is therefore biologically produced, and the material is used on a large scale for sportswear and uniforms. In the next step, we are working on the development of a fully bio-based polyester fiber in which the PTA component is also obtained from biomass raw materials, such as the inedible parts of sugar cane and wood waste.

Already in 2011, we succeeded in producing a prototype of such a polyester fiber made entirely from biomass. However, the expansion of production at the PX manufacturer we are working with has proven to be challenging. Currently, we are only producing small sample quantities, but we hope to start mass production in the 2020s.

Originally starting with yarn, now a leading global producer of synthetic fibers for decades, you also work to the ready-made product. The range extends from protective clothing against dust and infections to smart textiles and functional textiles that record biometric data. What are you planning in these segments?

In the field of protective clothing, our LIVMOA™ brand is our flagship material. It combines high breathability to reduce moisture inside the garment with blocking properties that keep dust and other particles out. The textile is suitable for a wide range of work environments, including those with high dust or grease levels and even cleanrooms. LIVMOA™ 5000, a high quality, also demonstrates antiviral properties and helps to ease the burden on medical personnel. The material forms an effective barrier against bacteria and viruses and is resistant to hygroscopic pressure. Due to its high breathability, it also offers high wearing comfort.

Our smart textile is called hitoe™. This highly conductive fabric embeds a conductive polymer – a polymer compound that allows electricity to pass through - into the nanofiber fabric. hitoe™ is a high-performance material for detecting biosignals, weak electrical signals that we unconsciously emit from our bodies.

In Japan, Toray has developed products for electrocardiographic measurements (ECGs) that meet the safety and effectiveness standards of medical devices. And in 2016, we submitted an application to the Japanese medical administrative authorities to register a hitoe™ device as a general medical device – this registration process is now complete. Overall, we expect the healthcare sector, particularly medical and nursing applications, to grow – not least due to increasing infectious diseases and growing health awareness among the elderly population. We will therefore continue to develop and sell new products for this market.

In 1885, Joseph Wilson Swan introduced the term "artifical silk" for the nitrate cellulose filaments he artificially produced. Later, copper, viscose and acetate filament yarns spun on the basis of cellulose were also referred to as artifical silk. Toray has developed a new innovative spinning technology called NANODESIGN™, which enables nano-level control of the fineness and shape of synthetic fibers. This is expected to create functions, aesthetics and textures that have not existed before. For which applications do you intend to use these products?

In NANODESIGN™ technology, the polymer is split into a number of microscopic streams, which are then recombined in a specific pattern to form a new fiber. By controlling the polymer flow with extreme precision, the fineness and cross-sectional shape of the fiber can be determined much more accurately than was previously possible with conventional microfiber and nanofiber spinning technologies. In addition, this technology enables the combination of three or more polymer types with different properties in one fiber – conventional technologies only manage two polymer types. This technology therefore enables Toray to specify a wide range of textures and functions in the production of synthetic fibers that were not possible with conventional synthetic fibers – and even to outperform the texture and feel of natural fibers. Kinari, our artificial silk developed with NANODESIGN technology, is a prime example here, but the technology holds many more possibilities – especially with regard to our sustainability goals.

What has the past period of the pandemic meant for Toray's textile business so far? To what extent has it been a burden, but in which areas has it also been a driver of innovation? What do you expect of the next 12 months?

The Corona catastrophe had a dramatic impact on the company's results: The Corona catastrophe had a dramatic impact on the company's results: In the financial year 2020, Toray's total sales fell by about 10% to 188.36 billion yen (about 1.44 billion euros) and operating profit by about 28% to 90.3 billion yen (about 690 million euros). The impact on the fiber and textile business was also significant, with sales decreasing by around 13% to 719.2 billion yen (approx. 5.49 billion euros) and operating profit by around 39% to 36.6 billion yen (approx. 280 million euros).

In the financial year 2021, however, the outlook for the fibers and textiles sector is significantly better: So far, the segment has exceeded its goals overall, even if there are fluctuations in the individual areas and applications. In the period from April to June, we even returned to the level of 2019. This is partly due to the recovering sports and outdoor sector. The fashion apparel market, on the other hand, remains challenging due to changing lifestyles that have brought lock-downs and home-office. We believe that a full recovery in business will not occur until the travel and leisure sector returns to pre-Corona levels.

Another side effect of the pandemic that we feel very strongly, is the growing concern about environmental issues and climate change. As a result, the demand for sustainable materials has also increased in the apparel segment. In the future, sustainability will be mandatory for the development and marketing of new textiles in all market segments. Then again, there will always be the question of how sustainable a product really is, and data and traceability will become increasingly important. In the coming years, the textile division will keep a close eye on these developments and develop materials that meet customers' needs.

Micromechanical Simulation of the Resilience of Nonwovens

Nonwovens are an important component of different products of several uses, e.g. transport of humidity in sanitary products, insulation materials or filters. Nonwovens are usually produced on large engineering facilities. For this, experimental studies of design with regard to the optimization of these nonwoven-structures prove to be very difficult.

Influence Design Parameters
There are so many parameters of design, as for example fibers, surface weight or type of nonwoven bonding and finishing that are affecting the properties of nonwovens. For the change of one single parameter, e.g. the material of fiber, it is necessary to adapt the whole process of fabrication from the spinning of the fibers via their stacking to the nonwoven hardening.

For the change of one single parameter, e.g. the material of fiber, it is necessary to adapt the whole process of fabrication from the spinning of the fibers via their stacking to the nonwoven hardening.

Following the production of such a prototype a time consuming and cost-intensive characterization of the properties of nonwovens carried out experimentally has to be done.  Therefore, for this reason detailed studies considering several parameters of design are uneconomic.

Thus, micromechanical models of simulation are developed at Fraunhofer ITWM in cooperation with Procter & Gamble Service GmbH (P & G). By means of these models it is possible to forecast numerically the effective properties of nonwovens for diverse parameters of design. To virtually modify and optimize individual parameters in this connection it is only necessary to adapt the corresponding inputs of the model.

Fast Predictions Possible
In this case, the focus of the numerical predictions is primarily lying on the time-dependent behavior of the nonwovens.  The dynamic properties can be determined by means of numerical simulation of cyclic measurements. In doing so, a good correspondence of simulation and measurements is obtained.

Compared to experiments the required time of simulation for the behavior in case of low frequencies does not change. Therefore, we can obtain rapid forecasts for the long-term behavior (month till years) and the corresponding resilience of nonwovens using numerical models. A lot of alternatives can be simulated and studied within a few hours.

The fact that not only effective (macroscopic) properties of nonwovens can be computed, but also local physical values such as distribution of tension in binding agents and fibres is a further advantage of this micromechanical  approach. So, the simulation contributes to a better understanding of the properties of nonwovens.

Future designs deal with an extension of the models with regard to simulation of the productionv processes. By this, a fully digitalized layout design of nonwovens, from the manufacturing process till the optimization of functionality is possible.

With “Next Horizons”, Heimtextil is presenting its design forecast for the new season 2022/23 – analysed by international trend researchers and packed with valuable inspiration and inspiring content. The new trend themes take sustainability and resource conservation in the heart of their approach. The international trade fair for home and contract textiles takes place from 11 to 14 January 2022 in Frankfurt am Main.

Three international design agencies form the Heimtextil Trend Council. Together, they develop a well-founded global vision of the coming interior trends. Alongside the Heimtextil Trend Council, Heimtextil management has established a trend forecast for the coming season and presented it live via an online conference on 1 September 2021 from Frankfurt am Main. Trend Council members Anja Bisgaard Gaede from SPOTT trends & business, Anne Marie Commandeur from Stiljinstituut Amsterdam and Kate Franklin and Caroline Till from London studio FranklinTill shared their insights into the future of the industry. Designers, interior architects and decorators get inspired by the design forecast for the new season.

Next Horizons: long-term and circular mindset
The Next Horizons are not a fixed goal or a finish line – they are mindsets. These are made up of long-term thinking, accepting that the best way to impact the world is simply not to. Paradoxically, we have begun our transition to sustainability by addressing the problems within our manufactured system instead of transforming our approach to not create waste or imbalance. Transforming our nexus begins with accepting our economies are embedded within nature. The composition of design should be accessed, made and recirculated in tune with a long-term and circular mindset and simply not create waste. The Heimtextil Trends 22/23 “Deep Nature”, “Hyper Nature”, “Beyond Identity” and “Empowered Identity” explore these new mindsets for “Next Horizons”.

Heimtextil Trends in a new digital format
With “Next Horizons”, Heimtextil is breaking new ground and, for the first time, making trend information fully available in a digital format. The brand-new online platform of Heimtextil introduces the trends richly illustrated via colours, short films, bespoke imagery, key designer features and a soundtrack. The new online platform and all trend activities are directed by SPOTT trends & business from Denmark.

The Future Materials Library is now digital
Curated by Futures Agency FranklinTill, The Future Materials Library was launched in 2020 and is now available online at www.heimtextil-trends.com/future. This collection of exciting interior material innovations from around the world celebrates radical designers, innovative manufacturers and environmentally conscious producers who are helping to turn the current, linear system of production and consumption into a circular model.

Heimtextil Trends 22/23 – overview
Deep Nature – Rebalance by relearning

“Deep Nature” explores our ecosystem’s strategies: it’s our legacy and future all at once. We need to relearn and give into untamed texture, slow process, natural structures and living colours. “Deep Nature” is a long-term transformation and relearning process which gives us the ability to rebalance the natural world for a regenerative future. The colour scale for “Deep Nature” has a harmonious and soft expression used for untamed patternmaking. Mouldy, herbal tones and delicate tones of blue and rouge create a calm, tonal, and earthy approach.

Hyper Nature – Reconnect with nature via technology
“Hyper Nature” is about reconnecting to nature through technology. The theme is a digital facilitator of nature’s blueprint, fusing technology and nature for a protopia state and creating a better tomorrow step by step. Responsive materials, technical fibres, fluid patterns and microscopic structure describes materials and textiles for “Hyper Nature”. Bioscience brings inspiration to colours of both bright and lucid and blurred nuances of green and grey. Reflections and artificial light create new perceptions of nature-based colours. Coral, salmon and light raspberry are highlights.

Beyond Identity – Values more than physical attributes
“Beyond Identity” addresses the future with hopeful messages and soft and powerful defiance toward existing norms, leaving identity in flux. For the world of home interiors and textiles “Beyond Identity” works with recycled synthetic fabric, vintage silk and satin, natural-coloured textiles and new cellulose-based textiles. They are formed via the uncontrolled colouration process of a pastel-coloured look resembling the constant flux of identity. The colours scale for “Beyond Identity” features a range of pastels, complemented with a familiar grey and pale khaki as muted transferral colours.

Empowered Identity – Empower artisanship to sustain culture
“Empower Identity” is about creating sustainable cultural connections, renewing artisan sources of inspiration in a collaborative way. Empowering Identity encourages forming new connections between heritage cultures and future generations. Recycled and heritage textiles combined with textile craft techniques as tufting, embroidered appliqué and Cross-stitch are in focus in “Empower Identity”. Primary colours resemble their colour pigment origins to support the heritage expression of the theme. Sparks of coral and a greyed lilac accompany these primary tones. Multi-coloured usage is key.
