From the Sector

The AVK – Industrievereinigung Verstärkte Kunststoffe – has once again presented its Innovation Awards to companies, institutes and their partners. Three composites innovations were recognised in each of the three categories – “Innovative Products/Applications”, “Innovative Processes” and “Research and Science” – at the new event JEC Forum DACH on 23 November 2021, the first edition of which was held in Frankfurt.

“As usual, the submissions included a lot of very interesting and promising products and processes this year. The Innovation Awards highlight the outstanding efficiency, cost-effectiveness and sustainability of fibre-reinforced plastics as well as the companies and institutes operating in the sector,” explains Dr. Elmar Witten, Managing Director of the AVK. The jury of leading experts from the industry honoured the following innovations this year:

Category “Research and Science”
First place in the “Research and Science” category was awarded to the German Aerospace Center (DLR) for its Bondline Control Technology (BCT). This innovative process is used for quality control and assurance of bonded joints. The core element is a porous fabric which is applied to a joining surface using an epoxy adhesive or matrix resin. Peeling away the fabric creates a chemically reactive and undercut surface and can also be used as a test to check adhesion to the substrate. BCT has potential in a variety of possible applications. For example, peel ply can be replaced by BCT fabric to produce composite components with an optimised joining surface. The cost-effective BCT peel test is suitable for coupon testing and process control. In addition, the combined adhesion test and surface pre-treatment can be used for quality assurance of bonded repairs on fibre composite structures.

Second place was taken by the Institute of Textile Technology (ITA) at RWTH Aachen University and its partners AEROVIDE GmbH, Altropol Kunststoff GmbH, Basamentwerke Böcke GmbH, TechnoCarbon Technologies GbR with “StoneBlade – Lightweight construction with granite for the wind industry”. This innovation enables manufacturers to reduce the amount of non-recyclable materials used in rotor blade construction. At the same time, it reduces the weight of these components and improves the mechanical properties relating to the stability of wind turbines. The innovative approach replaces glass-fibre reinforced plastic in the blade components with hard rock – a natural, cost-effective and recyclable lightweight material. The slabs of rock are cut and ground to a thickness of just a few millimetres and embedded in a fibre composite laminate with carbon fibre, which stabilises them for alternating load cases. The pre-stressed material is pressure-stable in the composite and can absorb tensile forces in the event of continuously alternating loads without any loss of stiffness.

Third place went to the Dresden University of Technology – Institute for Lightweight Construction and Plastics Technology (ILK) with its partner Mercedes Benz AG for the interdisciplinary development of a highly integrated inductive charging module for electric vehicles. The ultra-thin charging module was designed to make optimum use of space in the vehicle underbody without reducing ground clearance. An interdisciplinary approach was adopted for the development process. This involved the electrical, mechanical and process characterisation of high-frequency Litz wires, ferromagnetic foil and metal wire cloth as well as the creation of a simulation model. The result is a demonstrator for a charging system with a structural height of 15 mm and a total weight of 8 kg. It achieves a transmission efficiency of up to 92 percent at 7.2 kW nominal power and active air cooling. The hardware demonstrator was fabricated in a 3-step process using RTM and VARI techniques.

• Results of experiments conducted by the University of California’s prestigious Scripps Institution of Oceanography in San Diego provide further scientific proof that LENZING™ fibers offer an effective substitute to synthetic fibers that are part of the pressing problem of plastic pollution in our oceans.

Lenzing/San Diego – The Lenzing Group, a world-leading provider of wood-based specialty fibers, has received further scientific proof of the biodegradability of its fibers. In a study published in October 2021 , scientists from the prestigious academic research institute Scripps Institution of Oceanography (SIO) at the University of California, San Diego confirmed that wood-based cellulosic fibers biodegrade in the ocean within a short period of time at the end of their life cycle, making them a better alternative to fossil-based fibers. The research was the result of an independent project trying to understand the “end-of-life” scenarios for textiles and nonwovens discarded in the environment.

SIO has a global reputation for being one of the oldest, largest and most important marine research centers worldwide. In this study, SIO compared the degradation processes of nonwovens made from fossil-based synthetic materials such as polyester with those of cellulosic materials such as Lenzing’s wood-based lyocell, modal and viscose fibers in specific scenarios – under various real oceanic conditions and controlled aquaria conditions. The results of these experiments are striking: while wood-based cellulosic fibers fully biodegraded within 30 days, the fossil-based fibers tested were practically unchanged after more than 200 days.

The biodegradability of LENZING™ fibers was also tested in the laboratory of Organic Waste Systems (OWS) in Belgium – one of the world's leading companies in biodegradability and compostability testing – which showed data confirmed by those found with the real-life measurements at Scripps. The OWS assessment was conducted in accordance with applicable international standards and reflects relevant natural and artificial conditions in which biodegradation can occur. Certificates from the certification organization TÜV Austria show that LENZING™ fibers rapidly biodegrade in all test environments (soil, industrial composting, home composting, fresh water and marine water) within the time frames set by the applicable standards.

Lenzing also welcomes the EU’s targeted measures to combat plastic waste in general, such as those relating to the single-use plastic directive (EU) 2019/9043. In its recently adopted guidelines for implementing the directive, the EU Commission stipulates the specific products that fall under this category, which is a well-needed effort to provide clarity to the EU member states for their joint campaign against environmental pollution from plastic waste. Lenzing’s wood-based, biodegradable cellulosic fibers can be part of a sustainable and innovative solution to this man-made problem that will continue to grow. As of July 2021, the single-use plastic directive sets out standardized labelling requirements for certain products, either on packaging or on the products themselves, which include plastic-based feminine hygiene products and wet wipes for body care or household use. This is a start to tackle the problem: educate the consumer and offer alternative materials with better circularity.

The Hygiene Fibers Group of Indorama Ventures (IVL) came together at the Index Show to present an all-inclusive range of recycled and biodegradable solutions for Hygiene Fiber and Nonwoven applications.

The combination of polymers, technologies, processes and global reach supported by the Hygiene Fibers Group – one of three business segments that make up Indorama Ventures – positions it within the Hygiene industry to meet increasingly challenging market demand for innovative sustainable solutions within the hygiene sector. Across the six brands and companies that make up Hygiene Fibers Group – Auriga, Avgol, FiberVisions, Indorama Asia, Trevira and Wellman International – sustainability and supporting customers to achieve circular objectives is integral to all efforts and fundamental to the ethos of the Hygiene business segment.

At the Index Show, the Hygiene Fibers Group launched CiCLO®, a textile technology which allows polyester and other synthetic materials to biodegrade like natural materials do in wastewater treatment plant sludge, sea water and landfill conditions, reducing synthetic microfiber pollution generated during washing, and minimizing plastic accumulation in landfills caused by discarded textiles.

In line with the company’s commitment to support customers with high performance products, while also reducing the impact on the environment, several of the  Hygiene Fibers brands, including Wellman International, Trevira GMBH and Auriga, have been working closely over the last 12 months with the IAM team and the CiCLO® technology. Developments have focused on PET and rPET staple fiber and filament sustainable solutions for applications where recycling is particularly challenging, such as Hygiene, Home Textiles and Automotive applications.

Strengthening the profile of biodegradable offerings within the Hygiene Fibers Group’s sustainability portfolio, Trevira introduced a new range of bicomponent fibres based on PLA and PBS (polybutylene succinate) at the Index show. Both biopolymers offer an exceptional technological opportunity in terms of environmental care and sustainability, while delivering optimum performance. Equally to PLA, PBS is recyclable and up to 100% biodegradable under industrial conditions.

Efforts towards supporting customers to achieve circular objectives are a priority within the Hygiene Fibers Group. This is reflected in the recycled fibers expertise deployed across the segment. Four Hygiene Fibers Group brands, IVL Asia, Auriga, Trevira and Wellman International offer an extensive range of 100% recycled, accredited PET fibers, across a multitude of fiber and nonwovens applications.

The development and evolution of sustainable technologies is central to activity across IVL’s Hygiene Fibers Group, with particular focus on sustainable polyolefin solutions. FiberVisions and ES-FIBERVISIONS, leading Polyolefin mono and bico fiber brands and sister company Avgol, have partnered with UK-based Polymateria to commercially harness the innovative ‘biotransformation’ technology pioneered by Polymateria. The patented technology alters the properties of polyolefins to make them biodegradable in a natural process.  Other polyolefin sustainable innovations within the Hygiene Fibers Group were featured at Index include biosurfactant and biocolourant developments being undertaken by the Avgol team with FiberVisons progressing sustainable design solutions, including lightweight, high performance, reduced carbon solutions.

• JUMBO-Textil offers elastic high-tech braids – produced on high-tech systems

Developing narrow textile solutions for our customers – quickly, flexibly and precisely – that is our claim. For us and for our technology. Because first-class industrial solutions require first-class technology. Highly automated and digitally controlled. Technology like that found in our variation braider from Herzog – the high-performer among modern braiding machines. JUMBO-Textil is the first narrow textile manufacturer ever to produce elastic hole cords on the special system.

High-performance system for extremely stable textile components
The special system combines sophisticated bobbin lace technology with digital control and thus enables the production of highly complex, individually specifiable braided structures. The variation braider's technology ensures an uninterrupted fibre course across all branches. This not only allows individual, idiosyncratic geometries, it also and above all helps with the stability of the components. This is because where other methods create branching points that are susceptible to breakage due to laser cutting, seams or knots, the variation braider simply braids through the branched strands. As the fibre course is not interrupted in braided branches, the resilience of the textiles is significantly increased. And individual braids are created for very different applications.

Bobbin lace technology for highly complex structures
Unlike in classical braiding systems, the impellers of the variation braider are arranged in a square. Up to eight different strands can be braided and interlaced with the textile all-rounder. All bobbins can be programmed separately and thus the bobbin lanes can be combined variably and individually. JUMBO-Textil also produces tubular braids with precisely defined braided openings, triaxial braids and highly complex preforms with the variation braider. The geometries of the narrow textiles range all the way to net structures. For braided cables, we create stable connections in the core-sheath braiding by weaving the core and the protective sheathing, which provides protection especially at the turns: there is no longer any undesired core and sheath slippage.

Individual braid architectures – for automotive, outdoor and more
Complex non-elastic cords from the variation braider have been in operation at JUMBO-Textil for a long time. For hole cords – or bifurcation cords (from the Latin: furca, the fork) – the bobbin points are individually programmed so that the arrangement and length of the branching precisely meet the requirements. It is used, among others, in the automotive sector, in the construction industry and in the outdoor sector to hang or unhang elements without using metal.

Elastic hole cord from the elastics specialist
The elastic hole braids by JUMBO-Textil are new on the market. "The variation braider offers us fantastic possibilities: we can pre-configure what we want to braid and are completely free to do so. The repeat is computer-controlled," explains Holger Vehring, Project Engineer at JUMBO-Textil. "A seamless braided cable harness tubular that organises the cable mess (for automotive), braided hoses with defined openings for conductive elements in smart textiles or rehab applications, as tensioning elements in backpacks or functional clothing – the possible applications are vast. Thanks to this technology, textile – i.e. lighter, quieter and more flexible – components can be used for numerous applications in which metallic materials were previously used due to the fragile branching points."

• At this year’s INDEX from October 19th to October 22nd, Truetzschler Nonwovens, Truetzschler Card Clothing and Voith introduce new solutions for manufacturing a broad range of sustainable nonwovens for wipes, hygiene or medical textiles at booth 2327.

Plastic-free initiatives worldwide affect everyone: consumers, product developers, nonwoven producers and finally nonwoven machinery suppliers.

Truetzschler Nonwovens and Voith address the quest for more sustainable and affordable nonwovens in the wipes segment by two proven technologies for manufacturing pulp-based nonwovens. Firstly, WLS (Wet-Laid/Spunlaced) lines. More than a handful are in service worldwide and mainly target the flushable wipes market. At INDEX we’ll introduce our latest nextLevel/WLS baby and body wipes, a joint development by Voith and Truetzschler.

The second focus is on carded/pulp (CP) products. A CP line – including a TWF-NCT card placed between the HydroFormer and the AquaJet is already running to full capacity at customer site. Various CP materials, including innovative nextLevel/CP wipes, will be on display at the booth and invite visitors to discuss characteristics, benefits, line concepts and equipment.

When talking sustainable nonwovens, solutions for efficiently manufacturing biodegradable nonwovens from virgin cotton fibers, comber noils and viscose/lyocell fibers must not be missing. Visitors can look forward to directly comparing cotton nonwovens to a broad range of cellulose-based material.

Truetzschler Card Clothing, our in-house competence center with respect to card clothings and comprehensive service, presents its latest development, the Z wire for high-speed roller cards. A new geometry minimizes fiber fly and allows for better carding and more stable web forming.

Not only since 2021 has sustainability been a topic high on society’s agenda. And yet the importance of sustainability for consumers and companies has once again increased sharply as a result of the Corona pandemic, as numerous studies confirm. Then why is it often so difficult to implement this conviction in everyday life? One of the biggest obstacles to sustainable consumer behaviour is the lack of availability of alternatives.

In addition to changing consumer demands, the EU Commission's recent decision on the single-use plastics directive is also prompting many nonwovens manufacturers to look at alternative solutions. Kelheim Fibres is exhibiting at this year's INDEX in Geneva and online with bio-based fibers that offer an alternative to synthetic materials in a wide range of applications. The Bavarians have decades of experience in the nonwovens and hygiene sectors and work on individual customer-specific innovations.

"We want to make it easy for consumers to choose an environmentally friendly option. That’s the case when bio-based solutions offer the same performance as synthetic products," said Matthew North, Commercial Director at Kelheim Fibres." Our fibre technology allows us to create just that: unlike natural fibres, which are available already in fibre form and can only be treated on the surface, we can engineer the properties of our fibres they need for specific applications by specifically intervening in the production process. That way we combine nature - our fibres are made of wood pulp - with performance."

Kelheim's special fibres are made of wood pulp from sustainably managed sources, are produced in Kelheim in an environmentally friendly way and are fully biodegradable at the end of their product life. Kelheim Fibres is the first viscose fibre manufacturer in the world with an EMAS validated Environmental Management System and was awarded a dark green/light green shirt in the most recent Canopy HotButton-Ranking.

• Ramping Up Production of American-Made Polyester Tipped Swabs

The Biden Administration has awarded a contract for $6.5 million to U.S. Cotton LLC, the largest manufacturer of cotton swabs in the United States, to increase domestic production capability for polyester tipped swabs for home testing kits and mass testing applications to fight the COVID-19 pandemic.  Since the beginning of the pandemic, U.S. Cotton has retooled operations to produce over 400 million COVID testing kit swabs.

The Department of Defense (DOD), in coordination with the Department of Health and Human Services (HHS), announced the award today as part of the administration’s broader effort to increase domestic production capability for essential medical supplies.

U.S. Cotton, based in Cleveland, Ohio, said the company will increase its production capacity from 92 million polyester swab tips per month to approximately 371 million polyester swab tips per month by May 2022 to support domestic COVID-19 testing. The DOD contract award was funded through the American Rescue Plan Act (ARPA) to support the domestic industry base expansion for critical medical resources.

John Nims, President of U.S. Cotton said, “We are proud to be involved in a national effort to help deploy these testing kit swabs for the American people. These swabs are designed to make it easier for people at home to self-administer coronavirus tests and will also be used for mass testing applications, which is critically important. We greatly appreciate the collaboration with DOD and HHS to ramp up essential capacity of polyester-based synthetic swabs that will help in the fight against the pandemic.

“We continue to step up to meet our nation’s critical need for American-made coronavirus testing kit swabs on a massive scale. It is an honor to work with our government to help fight this pandemic and use our innovative technologies based here in the United States to fill a national and global demand for testing kits. I especially want to thank Senator Brown and Senator Portman for all their incredible support to help us retool and expand our operations in Cleveland. We can’t thank them enough for their tireless work and also want to recognize their hard working staff. As the Delta variant surges across the country, this timely investment will help in the fight against COVID by adding this much-needed, long-term surge capacity.”

Kim Glas, President and CEO of NCTO, said, “We want to sincerely thank President Biden, the Department of Defense, and the Department of Health and Human Services for leading this critical industrial expansion effort. We appreciate the administration’s commitment to expand the U.S. industrial base for these essential products.  We have a once-in-a-generation opportunity to onshore these critical supply chains long-term and we look forward to working with the administration and Congress to advance long-term solutions.”

• Testing and development achieve rigidity and safety milestone

Basaltex, pioneers in innovative uses of basalt fibres, has achieved a significant milestone in developing and testing a new composite material solution comprising fibres of basalt combined with EconCore’s patented honeycomb technology.

This new material development has greatly improved fire resistance and is highly rigid, as well as the usual honeycomb properties of light-weighting.

The company has tested the composite of basalt fibres, a bio resin and rPET honeycomb.

Filaments of only stone fibres are extruded at a temperature of 1450°C, similar to glass but with a number of advantages, not least the absence of boric acid in the process.

Combining this ecological fibre with EconCore’s sustainable technology using rPET, and the bioresin polyfurfuryl alcohol - 100% derived from a waste stream of sugar cane - make this a very sustainable and environmentally friendly product, unlike the majority of thermoset solutions in this type of application.

Railway applications require materials with enhanced fire resistance and the testing has shown that the EconCore-Basaltex solution fits these needs well, at the same time offering the perspective of drastic weight reduction against traditional monolithic GRPs used rather widely in train interiors.

Such sandwich panel could be deployed in applications such as cladding panels, partitions, tables and flooring. The thermoset skin layers give a fast cure at elevated temperature, meaning short cycle time and enabling automated production’.

As well as the railway interior application, this new material combination could be used in any application that requires fire performance combined with a low weight.
