From the Sector

The combination of high strength and rigidity with sustainability and a neutral carbon footprint makes flax the ideal raw material for natural fibre-reinforced plastics. vombaur offers composite textiles made of this natural fibre for the automotive, wind power, construction or sports industries and many other sectors.

Flax fibres are rigid and tear-proof. They have natural bactericidal properties, are virtually antistatic, stain resistant and easy to spin. Humans have taken advantage of these properties to manufacture robust, stain-resistant and lint-free textiles. Between the late 19^th and late 20^th centuries, cotton largely replaced natural fibres. Because flax can be grown in Europe and consumes less energy and water than cotton production, the material's importance is currently growing again, for both clothing and composites. Regional textile value added chains in Europe – flax makes them possible.

Ideal mechanical properties
vombaur makes the mechanical properties of flax usable for lightweight design. Because flax fibres are particularly rigid and tear-resistant, they ensure great stability in natural fibre-reinforced plastics (NFRPs). And thanks to their low density of 1.50 g/cm3, the fibres weigh virtually nothing. On top of this, fibre-reinforced plastics are less prone to splintering than glass fibre-reinforced plastics.

Excellent carbon footprint
The cultivation of flax binds CO₂ and the production of natural fibre-reinforced plastics (NFRPs) generates approximately one third less CO₂ emissions compared with conventional fibre-reinforced plastics. Energy consumption is substantially lower. This saves resources. The use of flax fibre tapes by vombaur in lightweight design applications also improves the product's carbon footprint and contributes to a secure, regional supply chain.

Recycling without impacting on quality
Flax offers another sustainability benefit: more recycling cycles than glass- or carbon fibre-reinforced plastics – without impacting on quality. Thermoplastic fibre-matrix prepregs are melted and reused in the recycling process. The natural fibres can be used in other products such as natural fibre-reinforced injection moulded parts.

Sustainable product developments for many industries
"Orthoses for high-performance sports, high-tech skis, wind turbines, components for the automotive industry or aerospace, but also modern window profiles – the application scope for our lightweight design flax tapes is amazingly diverse", as Carl Mrusek, Chief Sales Officer at vombaur explains. "After all, wherever flax tapes are used, three key properties come together: light weight, strength and sustainability".

Using recovered resin from discarded car bumpers, Autoneum’s sustainable Re-Liner technology transforms a previously unusable waste product into lightweight and durable wheelhouse outer liners. In addition to their high recycled content, the eco-friendly components require significantly less energy to produce than conventional alternatives. The innovation presents another important step towards a more sustainable circular economy and has now been nominated for the 2023 PACE Award.

Autoneum has been selected as one of the finalists for the 2023 Automotive News PACE Awards. Entering its 29th year, this prestigious award honors superior innovation, technological advancement and business performance among automotive suppliers.

Re-Liner is based on a core of polyolefins recovered from post-consumer bumpers and has a textile top layer made of fibers from recycled materials. “Autoneum has recognized the untapped potential of recovered resin from automotive bumper covers as a resource and is giving this former waste product a second life,” explained Dan Moler. “The core resin of Re-Liner is 100% automotive post-consumer recycled material, not just a filler or additive to a virgin material. Lightweight, durable, and sustainable wheelhouse outer liners based on this technology are expected to reduce waste generated by bumper covers by nearly one million kilograms in 2023.”

For more than a quarter century of a century, the PACE Award has honored innovations driven by automotive suppliers. The award is known in the global automotive industry for identifying and recognizing the latest game-changing innovation: from the plant floor to the product to the showroom. In 2000, Autoneum (then Rieter Automotive) already received a PACE Award for its Ultra-Light technology. In addition, two of the Company’s technologies have also been nominated as finalists in the past: Ultra-Silent in 2010 and Theta-Fiber in 2012.

Silence and resource efficiency are the order of the day in the development and optimization of electric vehicles. On the one hand, ever stricter emissions regulations worldwide are increasing demand for components that reduce noise pollution while helping vehicle manufacturers meet their sustainability targets. On the other hand, the absence of noise from the combustion engine in e-cars amplifies the disruptive effects of other noise sources in the passenger compartment. With Ultra-
Silent Tune, Autoneum now presents a new lightweight and environmentally friendly technology for underbody shields that reduces tire rolling noise both outside and inside the vehicle, thus improving not only acoustic performance but also driver comfort in electric cars.

Autoneum's Ultra-Silent Tune technology owes its sound-absorbing performance to acoustic chambers of different shapes and sizes. The chambers are created by applying an embossed polyester foil to the side of the Ultra-Silent underbody shield facing away from the noise source: they capture the sound waves emitted by the car tires, modulate them according to their respective geometry and reflect them back onto the porous carrier material. Compared to conventional single-layer underbody shields, whose acoustic performance is mainly determined by the noise-reducing properties of the product side facing the tires, Ultra-Silent Tune exploits both sides of the component, which significantly improves its acoustic absorption. Autoneum thus makes innovative use of the proven concept of traditional chamber absorbers, reducing exterior tire rolling noise.

Moreover, Ultra-Silent Tune combines optimized acoustic performance with the sustainability benefits of Autoneum's Pure technology Ultra-Silent. In addition to the high proportion of recycled PET fibers, underbody shields made from Ultra-Silent Tune can be manufactured from 100% polyester and thus be fully recycled at the end of vehicle life. Furthermore, the thickness of the multilayer construction can be flexibly adapted to the packaging spaces of different vehicle models. Underbody shields made from Autoneum's new Ultra-Silent Tune technology are already in pre-development at various vehicle manufacturers in Europe.

ERCA, Patagonia® and YKK announce the implementation of ERCA’s REVECOL®, a sustainable, innovative chemical agent, in YKK’s dyeing processes at their Vietnam production sites transforms common waste material, such as exhausted vegetable cooking oil, into an upcycled, certified high performance, safe textile chemical. ERCA has invested in circular practices to take waste material and use them as feedstocks to create new responsible chemical products.

Always searching for new sustainable innovations, REVECOL® caught the attention of Patagonia®. Driven by the goal to utilize non-extractive chemistry in their supply chain wherever possible, the brand teamed up with ERCA and trim supplier YKK to deploy REVECOL®.

REVECOL® LV-TS has a carbon footprint that is 72% lower* than the more conventional chemical auxiliaries produced by ERCA. Today ERCA produces a wide range of high-performance chemical auxiliaries made from used vegetable oil that are ZDHC, bluesign® approved and GRS certified.

ERCA is one of the first companies to have GRS certified chemical products, opening the door to circular chemical auxiliaries.

As part of their Sustainability Vision 2050, YKK is constantly working to deploy more sustainable chemical processes in their production. The ability to replace a commonly used dye chemical with a lower impact version was a no-brainer for YKK’s Vietnam management. REVECOL® is not only more sustainable, it is also more efficient, reducing the use of the dyeing auxiliary by 20% to 30%, thus  helping to lower YKK’s overall chemical usage.

B.I.G. Yarns unveils its new “SustainableYarns” platform, with Clerkenwell Design Week visitors the first to be invited to get on board and focus on what matters most for the design and manufacture of sustainable soft floorings.

The expert in polyamide (PA) 1 step 3 ply yarns offers a range of options for manufacturers to introduce sustainable yarns into carpet solutions and reach sustainability targets faster and more efficiently.

The Sustainable Yarns range creates opportunities to design with recycled content yarn (EqoCycle), to work with renewable resources (EqoBalance), and, following the launch of new polyamide 6 (PA6) EqoYarn at Clerkenwell Design Week, to also leverage the low-impact value chain.

New addition EqoYarn is a new low-impact PA6 carpet yarn based on the most recent innovations in polymer production, which enable yarn manufacturers to lower their carbon footprint by nearly 50% and give carpet manufacturers more options to reduce their impact.

For its EqoYarn Bulk Continuous Filament (BCF) production process, B.I.G. Yarns has selected the few best-in-class partners that have made major steps forward in terms of sustainability, and reduced their greenhouse gas emissions thanks to continuous investments in process efficiency, green energy, heat optimization and waste reduction. The result is EqoYarn with a carbon footprint of 4 kg CO2 eq/kg yarns, which is a CO2 reduction of up to 50% compared to conventional PA yarns.

EqoBalance PA6 yarns enable customers to reach an even higher CO2 reduction of up to 75%. Manufactured with polymers made from renewable resources such as organic waste from cooking oil instead of virgin or fossil feedstock, these yarns have a carbon footprint of 1.98 kg CO2 eq./ kg yarns. They help carpet manufacturers to create products with an extremely low carbon footprint.

EqoCycle PA6 yarns are fully recyclable and incorporate 75% recycled content originating from recycled and regenerated PA6 granules. With a carbon footprint of 4.64 kg CO2 eq./ kg yarns, they deliver the same high-quality performance of virgin PA6 yarn with the benefit of 37% CO2 reduction. EqoCycle yarns offer carpet manufacturers a sustainable alternative to help reduce the ecological footprint of their products and move towards a circular economy without jeopardizing the end-product quality.

In addition to the different CO2-reducing options, B.I.G. Yarns’ customers can access an unlimited colour range to elevate their designs. Its BCF technology for polyamide yarns, twisted and heat-set yarns, one-colour to multi-colour, between 650 and 15000 dTex, along with its colour studio, are available to support their creation of customised collections.

ITA Aachen - Digital ring spinning tester for recycled fibres enables spinning of fine yarns with high recycled fibres content
The Institut für Textiltechnik of RWTH Aachen University (ITA) will be exhibiting a digital ring spinning tester, which spins recycled fibres directly and conventionally with a particularly high content of 60-70 percent. Up to now, recycled yarns have mainly been rotor-spun in this blend ratio. This results in rather coarse yarns and is not suitable for finer textiles such as outerwear. Ring spinning of recycled yarns now enables the spinning of finer yarns and thus a higher application level for recycled materials.

A unique selling point of the ITA ring spinning tester is the simultaneous spinning in the direct spinning process from the sliver and in the classic ring spinning process. For this purpose, the strength and elongation of the spun yarn are determined online and digitally for the first time. The real-time measurement allows process parameters and yarn properties to be adjusted iteratively and quickly. The ring spinning tester was upgraded from an existing tester to Industry 4.0 standard and is operated via a tablet. Operation via tablet enables the adjustment of process parameters including online quality monitoring remotely from anywhere in the world.
 
For this purpose, the ring spinning tester is also able to produce fine ring spun yarns. These yarns made from recycled material opens up a multitude of further fields of application for woven and knitted goods. Now, for example, clothing and technical textiles can be made from recycled material, the production of which was not possible before - such as outerwear made from recycled material. The development of new industries and fields of application opens up new market potential for recycled yarns - also and especially for processing in Europe. This creates the opportunity to preserve key technologies and jobs in cost-intensive locations.

ITA Augsburg - Recycling Atelier: Walk4Recycling
The Recycling Atelier of the Institut für Textiltechnik Augsburg gGmbH on stand H3-A207 presents the textile recycling from used textiles into new products via the various process steps and, together with the industrial partners, opens up solution paths for industrial implementation.

Under the headline "Walk4Recycling", a tour of the fair shows the cycle of used textiles from used knitwear into a new knitted pullover via a ring yarn made from a blend of 65 percent recycled cotton and 35 percent virgin polyester. The key innovation here is the high proportion of recycled fibres from post-consumer textiles for a ring yarn of this fineness. Today, mainly coarse rotor yarns for low-quality textiles are spun from these materials. The industrial partners participating in the Walk4Recycling are partners of the Recycling Atelier and contribute with their technologies to the fact that fibre material from old clothes can be processed in various process stages into a yarn of new value and high-quality ready-made garments.

The Walk4Recycling offers visitors the opportunity to experience a complete recycling cycle with the numerous process stages from tearing the old textiles, preparing and spinning the fibres and knitting a new jumper live during the fair. Get detailed information on the mechanical recycling of clothing via QR code, website and flyer about the participating exhibitors and their machines and technologies. A short movie will give you additional insights into the various processes involved in the production of the jumper.

The Global Organic Textile Standard is pleased to announce the release of GOTS Version 7.0, which features an expanded scope of environmental and social criteria while maintaining a standard that is practicable for industrial production and appropriate for a wide range of products. During the regular year-long revision process, international stakeholders with expertise in organic production, textile processing, textile chemistry, human rights and social criteria, as well as representatives from industry, NGOs and civil society organisations, contributed to the new Version 7.0 through multiple consultation rounds. Final decisions were made by the multistakeholder GOTS Standard Revision Committee.

GOTS Version 7.0 provides a comprehensive solution for companies who want to produce organic textiles ensuring compliance with environmental and human rights due diligence along the entire supply chain, from field to finished product. With full traceability from origin to destination, GOTS certification provides an efficient means of verifying genuine sustainability efforts. GOTS 7.0 introduces new requirements to conduct risk-based due diligence of Certified Entities’ own operations and their supply chains based on the UN Guiding Principles for Business and Human Rights and the OECD guidelines. The Social Criteria section was substantially revised to include a broader human rights-focused approach. GOTS 7.0 now allows recycled organic fibres as additional materials. Key requirements, such as certified organic fibre content, a general ban on toxic and harmful chemicals such as PFAS, conventional cotton and virgin polyester restrictions, and social compliance management, are maintained in GOTS Version 7.0.

Some of the changes in Version 7.0 include:

• GOTS and the Manual for the Implementation of GOTS were restructured, and sections were grouped to reflect the standard’s scope.
• New due diligence criteria ensures that Certified Entities address their actual and potential negative impacts on human rights and the environment.
• GOTS Environmental Criteria, Product Stewardship, and Environmental Health and Safety (EHS) requirements will also apply to the subcontractors of chemical formulators.
• Criteria for the incoming organic material have been made stricter.
• Quinoline is included among the prohibited substances and some existing restrictions have been made tighter such as of “aniline, free”, residue limit is decreased to 20 mg/kg from 100 mk/kg.
• GOTS 7.0 reduces the permissible quantity of recycled synthetic (polymer) fibres in its certified products, taking into account the disadvantages associated with recycled synthetics, such as microplastics and poor quality.
• In the pursuit of circularity, GOTS will allow use of recycled GOTS Goods waste as an additional fibre in its certified products.
• GOTS Human Rights and Social Criteria will now require Certified Entities to respect internationally recognised human rights protocols, including the International Bill of Human Rights and other international human rights treaties.
• Criteria concerning Discrimination, Violence and Harassment were revised to make them more comprehensive and include the International Labour Organisation (ILO) Violence and Harassment Convention (C190).
• Certified Entities are now required to develop a plan to cover the living wage gap.
• GOTS Occupational Health and Safety criteria were revised to consider best international practices and recommendations from the ILO.

The substance graphene can become increasingly important as a component in textile catalysts when purifying water from textile dyeing as has been shown in a recently completed doctoral project at the University of Borås.

In his project, Milad Asadi, a new doctor in Textile Technology, has modified conventional yarn by encapsulating iron particles in graphene and developed a multifunctional smart e-textile. The focus was on developing a method for purifying wastewater from textile dyeing. The smart e-textile acts as a catalyst that causes the substance hydrogen peroxide to be formed, which is needed in order to break down pollutants in wastewater.

The project has generated a complete textile reactor for the treatment of wastewater through the so-called electro-Fenton technology, which is mainly used industrially to purify wastewater. The novelty of the technology is to use the properties of both graphene and iron, which is the main catalyst.

“Previous research has mainly been about the treatment of wastewater by using chemicals to break down the textile dyes. My project is the first where graphene, which is electrically conductive, is used to encapsulate iron. The e-textile can also be used several times, unlike when chemicals are used and which are then rinsed off. The challenge in the project was to scale up the technology so that the treated yarn can be fed into automatic knitting machines”, explained Milad Asadi.

The e-textile catalyst can be reused and hydrogen peroxide is formed internally inside the reactor, which reduces the use of biological catalysts, making the technology more sustainable compared to chemical methods.

Adient, a supplier of seating systems for the automotive industry, has entered into a cooperation with Swedish steelmaker H2 Green Steel (H2GS) to reduce the carbon footprint in its value chain.
 
On 1st September Michel Berthelin, Executive Vice President Adient EMEA, and Henrik Henriksson, CEO of H2 Green Steel, have mutually signed an agreement to supply fossil-free steel with low carbon footprint from 2026 on and subsequently use it in Adient's metal products.

Michel Berthelin explains the background to the cooperation: “As a company, we are committed to the Science Based Targets Initiative, a collaboration between leading global institutions to set a science-based climate target. We also support the Carbon Disclosure Project, which helps companies and cities to understand and disclose their environmental impacts. The decision to shift parts of the steel volume sourced for our production to a steel with low carbon footprint is part of our sustainability strategy. It is our goal to reduce emissions at our production sites that are caused directly by our own sources or indirectly by our energy suppliers by 75% by 2030. In parallel, we aim to reduce emissions along our supply chains by 35% over the same period. In doing so, Adient actively fosters the industry's transformation towards a more responsible use of natural resources.”

Steel from H2 Green Steel is produced with up to 95% less CO₂ emissions compared to conventional steel production. The company achieves this by replacing coal with green hydrogen in production and by the use of electricity from non-fossil sources. In this way, mainly water and heat are produced as waste products.
