The information chain will deal with Trevira CS technology, particularly sustainable product variants, the longevity of the textiles, the Trevira CS eco brand for flame retardant fabrics with recycled content, and the take-back program for Trevira CS fabrics. At the end of the chain, a prototype of a new product development will be presented, giving insight into the brand’s future sustainable development opportunities.

Once again, there will also be a special exhibition. The focus here will be on showcasing the special additional functions and properties that Trevira CS fabrics offer in addition to their flame retardancy. Visitors can look forward to a special staging: It’s showtime for the TEXTILE TALENTS by Trevira CS!

For the design of the special exhibition, all Trevira CS customers were invited to submit their latest Trevira CS products, distinguished by additional functions and/or special features, to the annual Trevira CS Fabric Competition. 227 products from 50 customers were submitted, from which about 150 were selected for the special exhibition. Several thousand meters of yarn will also be used in this year's special show.

Freudenberg recently completed the installation of 13,000m2 of photovoltaic cells on the roof of its new Nantong factory. With a total capacity of 1.6 MW, the new rooftop installation is projected to produce 1.5 million kWh of green electricity each year. In addition to reduced energy consumption from the grid, this new installation will lower CO2 emissions by approximately 1,200 tons/year.

Beyond the photovoltaic installation, Freudenberg has integrated sustainability into the Nantong factory’s design, with advances in energy conservation and emissions and loss reduction.
The factory uses valley voltage to cool water in its reservoir that is applied to A/C and machine temperature management during working hours. The new waste gas treatment technology enables hot water collected by heat exchangers to be directly reused in production, thereby reducing thermal energy waste. Furthermore, the factory applies a new multi-phase waste gas treatment technology to reduce volatile organic compounds (VOC) emissions. The factory has also incorporated new methods to improve the A-grade rates of bi-elastic interlinings and shirt interlinings, further reducing waste while improving garment quality.

As part of the Group’s sustainable development strategy, Freudenberg Apparel has also launched its House of Sustainability to minimize the impact of production processes on the environment and help customers achieve their sustainability goals, with responsible products across the seasons.

Fibres, fabrics, epoxy resins and adhesives from Sicomin have been used by Grand Largue Composites (GLC) to construct the first Class40 racing yacht to feature a significant quantity of flax-fibre reinforcements.
The yacht, called Crosscall, won the Class40 World Championships in June 2022 and is a prototype of the new Lift V2 design by Marc Lombard, one of the leading naval architects in this field.

Class40 is one of the most competitive fleets in yacht racing. The hulls of Class40 yachts must be light in weight, strong and stiff, and durable in the most extreme of conditions. Furthermore, to keep costs down, they cannot be reinforced with carbon fibres. The quality and reliability of the resins used for the infusion and lamination of the hulls are therefore of paramount importance.

Crosscall's cockpit was designed to be effectively non-structural, with the mainsheet, which can generate huge shock loads, supported separately. This would allow the cockpit to be made from a hybrid biaxial fabric comprising 50% flax fibres. Other parts of the boat that incorporate flax fibre include the tunnel, the engine cover, the ballast tanks and the cap. The rest of the boat is reinforced with 100% glass-fibre fabrics.

To help it realise this ambitious design, GLC, an infusion specialist, turned to its long-time material supplier, Sicomin. The hull was moulded and infused in one piece and the deck – including the hybrid flax-fibre cockpit – was also infused as a single part. The internal structure was then laminated into the hull by hand before the hull and deck were finally bonded together.

The infusion resin selected was Sicomin’s SR 1710, a high-modulus structural epoxy. Designed specifically for use in infusion and injection processes, it has exceptionally low viscosity and its low-reactivity hardener makes it suitable for the production of large parts. Composites components made from SR 1710 possess high interlaminar shear-strength and the resin retains its mechanical properties in wet environments.

Sicomin’s low-toxicity SR 8200 was used to laminate the internal structures onto the skin of the hull. Ideal for hand laminating, this system includes a choice of hardeners with a wide range of reactivities, which makes it equally suitable for making large or small parts. The hull and deck were joined together with Sicomin’s Isobond SR 7100, which demonstrates high fatigue strength and is very resistant to microcracking.

An epoxy bonding primer – called Undercoat EP 215 HB+ and supplied by Sicomin’s sister company, Map Yachting – was applied to the moulds first to make demoulding easier. It also serves as an undercoat in the polyurethane exterior paint system that is used instead of gelcoat to protect the epoxy hull from UV damage.

Since the launch of Crosscall, GLC has started building a second Lift V2 Class40 and a third one is now planned, both for which Sicomin will supply the materials.

The Supervisory Board of Lenzing AG, a world-leading provider of sustainably produced specialty fibers for the textile and nonwoven industries, has appointed Nico Reiner as its new Chief Financial Officer. Mr. Reiner will join Lenzing’s Managing Board led by Chief Executive Officer Stephan Sielaff on January 1, 2023. He will succeed Chief Financial Officer Thomas Obendrauf, who is leaving the company of his own volition after seven years.

Nico Reiner has held several positions in his professional career to date, including CFO at globally operating companies such as Schüco Group, AL-KO Group and Pfleiderer Group, as well as management consultant roles. His most recent appointment was as CFO of Vacuumschmelze GmbH & Co. KG, a global player with headquarters in Hanau that specializes in the development, production and marketing of magnetic materials.

After two years of joint collaboration and research the Swiss Textile Recycling Project “Texcircle” comes to an end. Partners and stakeholders have worked on the vision of a textile cluster where materials flow in circular loops. The goal of the project was to develop high-quality yarns and products incorporating such a large amount of recycled textiles as possible. In the end, several product prototypes from carpets, socks, and curtains to pullovers, padding and accessories have been developed with at least 50 % recycled fiber up to 80 % recycled fibers and yarns.

Europe has a waste problem of 7.5 million waste of which only 30-35 % is collected and less than 1 % of the textile and clothing worldwide is recycled into textiles and clothing again. It is as well found that around 80 % of the impact of a textile product lies in the design.

Together with the design research expertise of the Lucerne University of Applied sciences and arts, the spinning expertise of Rieter and the sorting and collection expertise of Texaid, systems should be created where products of high quality can be produced of recycled fiber. On board were the expertise of further Cluster partners of Brands, Retailers, and the public sector to see how a joint Cluster and system coukld be established.

The Project Texcircle and cluster is led by the Lucerne University of Applied Sciences and Arts – Art  & Design, and in collaboration with Coop, Rieter, Jacob Rohner AG, Ruckstuhl AG, TEXAID as well as workfashion.com ag. Furthermore, Bundesamt für Zivildienst ZIVI, NIKIN AG, and Tiger Liz Textiles are supporting the project. The project is funded by Innosuisse.

Furthermore, collaboration partners from all over Europe contributed to the project to enable these prototypes and systems.

Through joint developments from the design, the collecting, sorting trials, tearing, and spinning trials until the actual production trials and product testing. The partners were able to recycle 2.5 Tons of pre-and post-consumer textile waste into product prototypes with a promising commercial interest. From socks, west, and pullovers to non-woven felts and accessories to carpets and curtains. Through our 2 years of collaboration, the teamcame across several hurdles in the textile recycling value chain which could be tackled. This was a proof of concept that a circular system is possible and the industry now has to enable this at full scale.

The textile industry is the third largest consumer of plastics. While growth rates in the production of fibres and textiles are high, the circular economy has hardly become established in this segment. The EREMA Group is now intensifying development of recycling solutions for this application with their new fibres and textiles business unit. Currently, the focus is on PET fibre materials from fibre production and subsequent processing steps. Technologies for recycling mixed fibre textiles from textile collection sources are to follow in a follow-up project phase.

"With EREMA's VACUREMA® and INTAREMA® technology and PURE LOOP's ISEC evo technology, our company group already has an extensive range of machines for fibre and PET recycling applications. For ecologically and economically sound recycling, however, new technological solutions are needed to use the recycled fibres in higher-value end applications and to achieve a functioning circular economy," explains Wolfgang Hermann, Business Development Manager Application Fibres & Textiles, EREMA Group GmbH. The initial focus will be on PET, regarded as a key material for the production of synthetic fibres. The aim is to find recycling solutions that allow PET fibre materials to be prepared for reuse in PET fibre production processes. This is a significant step for the circular economy because PET fibres in textiles account for about two-thirds of the total volume of PET.

In this development work, the EREMA Group can build on existing know-how. Proven recycling technologies have been combined with a new IV optimiser. "This extends the residence time of the PET melt, which is particularly necessary in fibre recycling to efficiently remove spinning oils. Our recycling process also increases the IV value of the PET melt after extrusion back to the specific level that is essential for production of the fibre," explains Hermann. Waste PET fibre from production processes can therefore be further processed into rPET filament fibre, carpet yarn and staple fibre.

Fibre test centre with plant to test customers' materials
In order to accelerate development work, EREMA opened its own fibre test centre a few months ago, where a cross-company team is working on recycling solutions for fibre-to-fibre applications.

• Collaboration between Indorama Ventures and Toyobo to meet growing global demand for airbags
• Newly completed plant in Thailand will supply high-performance nylon yarn to customers in the automotive safety sector

Indorama Ventures Public Company Limited (IVL) celebrated the completion of a plant to manufacture high-performance nylon yarn for automobile airbags. The new plant in Rayong, Thailand, was constructed by Toyobo Indorama Advanced Fibers Co., Ltd. (TIAF), a joint venture that Indorama Ventures established with Toyobo Co., Ltd in November 2020.

The plant, which has been built on the site of Indorama Polyester Industries PCL (IPI) in Rayong Province, will deliver 11,000 tons of high-performance yarn per year to meet global demand for airbags that is expected to grow by 3 percent to 4 percent annually as automakers equip vehicles with more airbags and emerging economies require cars to adopt more safety features. Test production is scheduled to start in October 2022 with the goal of starting commercial production in the middle of 2023.

In 2014, Indorama Ventures and Toyobo jointly acquired Germany’s PHP Fibers GmbH, a leading airbag yarn maker. Since then, both companies have strengthened their relationship with a focus to expand in the automotive safety sector. Mr Christopher Kenneally, based in Bangkok, leads IVL’s Fibers segment, which produces fibers and yarns across its Hygiene, Mobility and Lifestyle verticals. Mr Ashok Arora, with over 30 years of experience in fibers and polymer operations, will helm TIAF as CEO while maintaining his role as CTO with IVL Fibers.

The garment is part of the New Cotton Project, an EU Consortium of key players united to demonstrate the potential of circular garment production
adidas by Stella McCartney presented a first of its kind sportswear garment designed to demonstrate the potential of a circular fashion ecosystem. Joining forces with leading names and innovators in the fashion industry to create, test, and innovate, the tracksuit forms the pinnacle expression of the brand’s pilot circularity program, Made to Be Remade. A take-back scheme where consumers can wear it down and then return it by scanning a QR code via the product so it can be remade. Moving adidas closer to its goal to help end plastic waste.

It’s currently estimated that just under 1% of all textiles worldwide are recycled into new textiles, so it’s vital the textile industry comes together to learn and knowledge-share. Scheduled across a three-year period, the consortium which includes partners such as Frankenhuis have collected and sorted post-consumer end-of-life textiles, which using pioneering Infinited Fiber technology have been regenerated into a new man-made cellulosic fiber called Infinna™ - which looks and feels just like virgin cotton. This is then turned into a yarn blended with organic cotton, for garment production.

Designing the tracksuit, made using viscose (60% viscose, 40% organic cotton) as a consortium member took the process from a linear to a circular model , as the apparel’s function and style were of equal focus to the garment’s end of life existence.

At the end of the project, consortium partner Aalto University, a Finnish multidisciplinary community specialising in science, art, technology , and design, will distribute learnings with the industry and bring this potential circular design solution to the ever-eco-conscious consumer.

The Lenzing Group, a leading provider of wood-based specialty fibers, is expanding its global clean electricity portfolio by gradually transitioning to green energy at its production site in Nanjing. This will enable its Chinese subsidiary Lenzing Nanjing Fibers to use electricity derived solely from renewable sources from 2023 onwards and reduce the site’s carbon emissions by 100,000 tonnes annually. Lenzing only recently announced the transition to green electricity at its Indonesian production facility.

In 2019, Lenzing became the first fiber producer to set a target of halving its carbon emissions by 2030 and becoming climate neutral by 2050. This carbon reduction target has been recognized by the Science Based Targets Initiative. In Nanjing, Lenzing is currently investing in cutting its carbon emissions and converting a standard viscose production line to 35,000 tonnes of TENCEL™ branded modal fibers. Thanks to this move, the Chinese site will exclusively produce eco-friendly specialty fibers.

The company aims to generate more than 75 percent of its fiber revenue from the wood-based, biodegradable specialty fibers business under the TENCEL™, LENZING™, ECOVERO™ and VEOCEL™ brands by 2024. With the launch of the lyocell plant in Thailand in March 2022 and the investments in existing production sites in China and Indonesia, the share of specialty fibers in Lenzing’s fiber revenue is set to exceed the 75 percent target by a significant margin as early as 2023.

The future of e-mobility will be determined in particular by safe battery enclosures. As batteries for electric vehicles become more performant, higher volumetric energy density plays a crucial role. If more energy is to be stored in less installation space, new material and design solutions are required. The development of suitable enclosures made of safe and highly robust lightweight materials is also required. This is a case for the Aachen Centre for Integrative Lightweight Production (AZL). A project on cell-to-pack battery enclosures for battery-electric vehicles, which has been eagerly awaited in the industry, will start in October this year there.

The design of battery housings is crucial for safety, capacity, performance, and economics. The Cell-to-Pack project, which is starting now, will focus on developing concepts for structural components and for producing them based on a variety of materials and design approaches. The concepts will be compared in terms of performance, weight and production costs, creating new know-how for OEMs, producers and their suppliers throughout the battery vehicle value chain. Companies are now invited to participate in this new cross-industry project to develop battery enclosure concepts for the promising and trend-setting cell-to-pack technology.

The basis for the project is the lightweight engineering expertise of the AZL experts, which they have already demonstrated in previous projects for multi-material solutions for module-based battery housings. Together with 46 industry partners, including Audi, Asahi Kasei, Covestro, DSM, EconCore, Faurecia, Hutchinson, Johns Manville, Magna, Marelli and Teijin, 20 different multi-material concepts were optimized in terms of weight and cost and compared with a reference component made from aluminum. All production steps were modelled in detail to obtain reliable cost estimates for each variant. Result: depending on the concept, 20% weight or 36% cost savings potential could be identified by using multi-material composites compared to the established aluminum reference.

It is expected that the design concept of battery enclosures will develop in the direction of a more efficient layout. In this case, the cells are no longer combined in modules in additional production steps, but are integrated directly into the battery housing. The elimination of battery modules and the improved, weight-saving use of space will allow for higher packing density, reduced overall height and cost saving. In addition, various levels of structural integration of the battery housing into the body structure are expected. These new designs bring specific challenges, including ensuring protection of the battery cells from external damage and fire protection. In addition, different recyclability and repair requirements may significantly impact future designs. How the different material and structural options for future generations of battery enclosures for the cell-to-pack technology might look like and how they compare in terms of cost and environmental impact will be investigated in the new AZL project. In addition to the material and production concepts from the concept study for module-based battery enclosures, results from a currently ongoing benchmarking of different materials for the impact protection plate and a new method for determining mechanical properties during a fire test will also be incorporated.

The project will start on October 27, 2022 with a kick-off meeting of the consortium, interested companies can still apply for participation until then.
