From the Sector

At this year's JEC World 2024 from 5 to 7 March, KARL MAYER GROUP will be exhibiting with KARL MAYER Technical Textiles and its STOLL Business

One focus of the exhibition will be non-crimp fabrics and tapes made from bio-based yarn materials for the reinforcement of composites.

"While our business with multiaxial and spreading technology for processing conventional technical fibres such as carbon or glass continues to do well, we are seeing increasing interest in the processing of natural fibres into composites. That's why we have a new product in our trade fair luggage for the upcoming JEC World: an alpine ski in which, among other things, hemp fibre fabrics have been used," reveals Hagen Lotzmann, Vice President Sales KARL MAYER Technische Textilien.

The winter sports equipment is the result of a subsidised project. The hemp tapes for this were supplied by FUSE GmbH and processed into non-crimp fabrics on the COP MAX 5 multiaxial warp knitting machine in the KARL MAYER Technical Textiles technical centre.

The STOLL Business Unit will be focussing on thermoplastic materials. Several knit to shape parts with a textile outer surface and a hardened inner surface will be on display. The double-face products can be made from different types of yarn and do not need to be back-moulded for use as side door panels or housing shells, for example. In addition, the ready-to-use design saves on waste and yarn material.

At this year's JEC World, STFI will be presenting highlights from carbon fibre recycling as well as a new approach to hemp-based bast fibres, which have promising properties as reinforcement in lightweight construction.

Green Snowboard
At JEC World in Paris from 5 to 7 March 2024, STFI will be showcasing a snowboard from silbaerg GmbH with a patented anisotropic coupling effect made from hemp and recycled carbon fibres with bio-based epoxy resin. In addition to silbaerg and STFI, the partners Circular Saxony - the innovation cluster for the circular economy, FUSE Composite and bto-epoxy GmbH were also involved in the development of the board. The green snowboard was honoured with the JEC Innovation Award 2024 in the “Sport, Leisure and Recreation” category.

VliesComp
The aim of the industrial partners Tenowo GmbH (Hof), Siemens AG (Erlangen), Invent GmbH (Braunschweig) and STFI united in the VliesComp project is to bring recycled materials back onto the market in various lightweight construction solutions. The application fields "Innovative e-machine concepts for the energy transition" and "Innovative e-machine concepts for e-mobility" were considered as examples. On display at JEC World in Paris will be a lightweight end shield for electric motors made from hybrid nonwovens - a mixture of thermoplastic fibre components and recycled reinforcing fibres - as well as nonwovens with 100% recycled reinforcing fibres. The end shield was ultimately manufactured with a 100% recycled fibre content. The tests showed that, compared to the variant made from primary carbon fibres using the RTM process, a 14% reduction in CO₂ equivalent is possible with the same performance. The calculation for the use of the prepreg process using a bio-resin system shows a potential for reducing the CO₂ equivalent by almost 70 %.

Bast fibre reinforcement
To increase stability in the plant stem, bast fibres form in the bark area, which support the stem but, in contrast to the rigid wood, are very flexible and allow slender, tall plants to move in the wind without breaking.A new process extracts the bast bark from hemp by peeling.The resulting characteristic values, such as tensile modulus of elasticity, breaking strength and elongation, are very promising in comparison with the continuous rovings made of flax available on the market.The material could be used as reinforcement in lightweight construction.At JEC World, STFI will be exhibiting reinforcing bars that have been processed into a knitted fabric using a pultrusion process based on bio-based reinforcing fibres made from hemp bast for mineral matrices.

Textiles for technical applications often derive their special function via the application of coatings. This way, textiles become, for example wind and water proof or more resistant to abrasion. Usually, petroleum-based substances such as polyacrylates or polyurethanes are used. However, these consume exhaustible resources and the materials can end up in the environment if handled improperly. Therefore, the German Institutes of Textile and Fiber Research Denkendorf (DITF) are researching materials from renewable sources that are recyclable and do not pollute the environment after use. Polymers that can be produced from bacteria are here of particular interest.

These biopolymers have the advantage that they can be produced in anything from small laboratory reactors to large production plants. The most promising biopolymers include polysaccharides, polyamides from amino acids and polyesters such as polylactic acid or polyhydroxyalkanoates (PHAs), all of which are derived from renewable raw materials. PHAs is an umbrella term for a group of biotechnologically produced polyesters. The main difference between these polyesters is the number of carbon atoms in the repeat unit. To date, they have mainly been investigated for medical applications. As PHAs products are increasingly available on the market, coatings made from PHAs may also be increasingly used in technical applications in the future.

The bacteria from which the PHAs are obtained grow with the help of carbohydrates, fats and an increased CO₂ concentration and light with suitable wavelength.

The properties of PHA can be adapted by varying the structure of the repeat unit. This makes polyhydroxyalkanoates a particularly interesting class of compounds for technical textile coatings, which has hardly been investigated to date. Due to their water-repellent properties, which stem from their molecular structure, and their stable structure, polyhydroxyalkanoates have great potential for the production of water-repellent, mechanically resilient textiles, such as those in demand in the automotive sector and for outdoor clothing.

The DITF have already carried out successful research work in this area. Coatings on cotton yarns and fabrics made of cotton, polyamide and polyester showed smooth and quite good adhesion. The PHA types for the coating were both procured on the open market and produced by the research partner Fraunhofer IGB. It was shown that the molten polymer can be applied to cotton yarns by extrusion through a coating nozzle. The molten polymer was successfully coated onto fabric using a doctor blade. The length of the molecular side chain of the PHA plays an important role in the properties of the coated textile. Although PHAs with medium-length side chains are better suited to achieving low stiffness and a good textile handle, their wash resistance is low. PHAs with short side chains are suitable for achieving high wash and abrasion resistance, but the textile handle is somewhat stiffer.

The team is currently investigating how the properties of PHAs can be changed in order to achieve the desired resistance and textile properties in equal measure. There are also plans to formulate aqueous formulations for yarn and textile finishing. This will allow much thinner coatings to be applied to textiles than is possible with molten PHAs.

Other DITF research teams are investigating whether PHAs are also suitable for the production of fibers and nonwovens.

INDA, the Association of the Nonwoven Fabrics Industry, will join the ISSA – The Worldwide Cleaning Industry Association to host the 2024 Clean Advocacy Summit, April 10-11, in Washington, D.C. This advocacy and fly-in summit will offer participants the “inside scoop” on the key public policy issues facing their industry, including labor and supply chain challenges, cleaning product regulations, promoting healthy workplaces, ending period poverty, and more.

The summit will include networking opportunities and scheduled meetings with members of Congress and their staff to discuss key policies and legislation pertaining to the nonwovens industry. Attendees will have the chance to advocate for their businesses to support innovation, growth, and sustainability within the industry, while also highlighting their contributions to economic development and job creation.

Haelixa, the trailblazer of physical traceability solutions, has partnered with Trudel Silk, a market leader for sustainable organic and recycled silk products. This collaboration brings traceability and transparency to silk production.

Silk is one of the finest and smoothest fabrics; the better the quality of the silk, the more luxurious it feels to the touch. To create the best quality silk, the conditions for mulberry cultivation must be up to the highest standards. A healthy micro-ecosystem in the fields translates to top-grade silk cocoon quality. At Trudel, this is the environment they have created for the vertical integration of their business. Trudel aims to succeed at every stage of the process, which can only be accomplished through the active involvement and visible cooperation of all market players. These players include farmers, reeling mills, twisting/spinning mills, weaving mills, dyeing and printing mills, and brands. They are involved in every step, from the cultivation of mulberry trees to the production of silk fabrics.

Haelixa and Trudel have collaborated to improve silk’s robust and consistent traceability. As the demand for validation of the silk value chain increases, they have partnered with groups from Italy and Asia to develop a unique solution that uses DNA markers to trace the entire supply chain of silk production. This innovative approach ensures each silk product’s ethical sourcing.

The silk fibers used in their spun silk yarns are marked with a specific DNA per farm set selected by Trudel. Throughout the supply chain, samples of yarn, fabrics, and finished products undergo testing to verify the presence of original silk fibers. Based on the reporting, the brand can trace the finished accessories or garments to Trudel.

INDA, the Association of the Nonwoven Fabrics Industry, announced that registration and tabletop exhibit reservations are open for the World of Wipes® (WOW) International Conference. WOW 2024 will take place June 17-20 at the Hyatt Regency Minneapolis, Minneapolis, MN. The theme for this year’s event is “Wipes Innovation & Sustainability – From Inception to Perfection.”

WOW will feature content in responsible sourcing, end-of-life solutions, and innovations in sustainability. Industry leaders, such as The Clorox Company, Kimberly-Clark Professional, and Nice-Pak, amongst others, will present their sustainability insights in formulations, industrial and institutional wipes, alternatives to plastics, production technologies, recycling options, and regulatory issues.

Nach drei erfolgreichen Messetagen ist am 25. Januar die internationale Fabric Trade Show MUNICH FABRIC START für die Saison Spring.Summer 2025 zu Ende gegangen. Die Denim Trade Show BLUEZONE und der Innovationshub KEYHOUSE schlossen bereits am Mittwochabend ihre Pforten. Das Resümee des Treffens der europäischen Fashionbranche: Wir erleben eine Rückbesinnung auf unsere Wurzeln, um so dem wachsenden Bedürfnis nach Orientierung Rechnung zu tragen – ergänzt um eine Vielfalt spannender nachhaltiger und AI-gestützter Lösungen, die der Branche den Weg in die Zukunft ebnen können.

Unter dem Motto „CLARITY“ konnten Designer, Buyers, Product Manager und Entscheider:innen die Neuheiten und Services von rund 1.000 Anbietern aus aller Welt, verteilt auf die acht Areas ADDITIONALS, FABRICS, ReSOURCE, BLUEZONE, DESIGN STUDIOS, KEYHOUSE, SUSTAINABLE INNOVATIONS sowie THE SOURCE für die neue Saison sichten.

Mit Blick auf Trends für Spring.Summer 2025 zeigten sich verschiedene Entwicklungen: Einerseits eine klare Rückbesinnung auf Altbewährtes, bei dem handwerkliches Geschick und klare Formen im Vordergrund stehen. Durchbrochen wird die Nostalgie stellenweise durch ergänzende Statement-Pieces aus dem Athleisure- oder, im Bereich der Damenmode, Lingerie-Bereich. Denim ist in der kommenden Saison allgegenwärtig – nicht zuletzt, da es sich dabei um das wohl demokratischste Fabric handelt, das in jegliche Güte- und Preisklassen übersetzt werden kann. Im Bereich der Damenmode wird es neue Interpretationen des Herrenhemds zu sehen geben, das in seinen klassisch maskulinen Formen dekonstruiert wird. Der Fokus richtet sich auf natürliche Materialien wie Leinen und Hanf. Nicht zuletzt im Bereich einer neuen casual Work Wear, hier vor allem in Kombination mit warmen Neutraltönen und gebrochenen Facetten von Weiß. Pastells werden weiterhin allgegenwärtig bleiben – allerdings in neuen Nuancen und ausbalanciert durch eine erdige Farbpalette.

Das Vortragsprogramm stand diesmal vor allem im Zeichen der Nachhaltigkeit – ob natürliche innovative Fasern und ihr disruptives Potential für eine nachhaltigere Fashionbranche, Recycling-Thematiken und damit verbundene EU-Regulatorik, die die Branche herausfordern werden, sowie hilfreiche Anleitungen dazu, wie sich die verschiedenen Akteure schon heute darauf vorbereiten können. Plattformen wie das KEYHOUSE leisten dazu einen zentralen Beitrag und schlagen die Brücke zwischen jungen, kreativen Denker:innen, der Forschung und Akteuren der Branche.

Die BLUEZONE hat am 23. und 24. Januar die Zenith Area einmal mehr in einen Denim-Hot-Spot verwandelt. Die Blue-Blooded-Community traf sich hier, um die Zukunft der Denimbranche auszuloten. Ein zentrales Thema bleibt die Transformation der Denimindustrie hin zu noch mehr Nachhaltigkeit: Cradle-2-Cradle-Konzepte, innovative Recyclingverfahren und ressourcenschonende Wasch-, Färbe- und Finishingtechnologien waren vielfach das inhaltliche Zentrum der Kollektionspräsentationen, von Stand- und Gangdiskussionen sowie den Trendvorträgen. So wurde der inzwischen von 53 marktführenden Denimunternehmen unterzeichnete Denim Deal auf der BLUEZONE Stage initial in Deutschland vorgestellt. Er verfolgt das Ziel, den Einsatz von Recyclingmaterialien in neuen Textilprodukten verbindlich zu machen. Die Hall of Fame machte das Leitmotiv der BLUEZONE „Signature“ dadurch erlebbar, dass sie live Personal-Pieces von Szeneikonen wie Jason Denham, Adriana Galijasevic, Adriano Goldschmied oder Renzo Rosso zeigte und deren jeweilige Geschichte erzählte. Persönliche Begegnung und Austausch waren auch das Motto der MUNICH FABRIC NIGHT, auf der am Abend des ersten Messetags alle MUNICH FABRIC START Aussteller:innen und Besucher:innen den Dancefloor im Dampfdom der Motorworld zum Kochen brachten.

Während der drei Messetage kamen 11.700 Besucher:innen in das Münchner MOC sowie die Zenith Area. Viele wichtige Brands, wie adidas, Akris, Alberto, Alpha Tauri, Anna van Toor, Armed Angels, Baldessarini, Bestseller, Betty Barclay, BMW, Bogner, Brax, C&A, Carhartt, Closed, Comma, Condé Nast, Digel, Diesel, Drykorn, Escada, Eterna, Ganni, Hessnatur, Holy Fashion Group, HSE, Hugo Boss, Inditex, Joop, Katag, Lagerfeld, Lanius, Lodenfrey, Mac, Maloja, Marc Cain, Marc O’Polo, März, Mey, More&More, Mustang, MyTheresa, Oui, Remei, Riani, Roxy, s.Oliver, Schumacher, Seidensticker, Sportalm, Talbot Runhof, Tchibo, Tom Tailor, Tory Burch, Windsor und Wolford waren vor Ort. Die Besucher:innen kamen aus 58 Ländern, neben Deutschland überwiegend aus dem osteuropäischen Raum, Italien, Skandinavien, UK, den Benelux-Staaten, aber auch aus Südamerika, den USA und den UAE, Saudi Arabien und Ozeanien. Abgerundet durch ein umfassendes Begleitprogramm mit prominenten und internationalen Speaker:innen aus den verschiedensten Bereichen der Branche und zahlreichen Möglichkeiten zum Netzwerken überzeugte die MUNICH FABRIC START auch diese Saison mit ihrem ganzheitlichen Konzept.

Bereits in wenigen Monaten steht mit der VIEW Premium Selection am 18. und 19. Juni in der Motorworld der nächste zentrale Termin für die europäische Fashionbranche an – dann zum Auftakt für die Saison Autumn.Winter 25. Der Junitermin bietet einen ersten inspirierenden Überblick über kommende Trends und Neuerungen in den Bereichen Fabrics, Denim & Sportswear, Additionals und Design Studios für die kommende Saison, und damit bereits vor dem bedeutenden September-Termin, als essenziellem Zeitpunkt für schnelles Ordern, Innovationen und Entwicklungen der Modeindustrie.

Celanese Corporation, a specialty materials and chemical company, and Under Armour, Inc., a company in athletic apparel and footwear, have collaborated to develop a new fiber for performance stretch fabrics called NEOLAST™. The innovative material will offer the apparel industry a high-performing alternative to elastane – an elastic fiber that gives apparel stretch, commonly called spandex. This new alternative could unlock the potential for end users to recycle performance stretch fabrics, a legacy aspect that has yet to be solved in the pursuit of circular manufacturing with respect to stretch fabrics.

NEOLAST™ fibers feature the powerful stretch, durability, comfort, and improved wicking expected from elite performance fabrics yet are also designed to begin addressing sustainability challenges associated with elastane, including recyclability. The fibers are produced using a proprietary solvent-free melt-extrusion process, eliminating potentially hazardous chemicals typically used to create stretch fabrics made with elastane.

NEOLAST™ fibers will be produced using recyclable elastoester polymers. As end users transition to a more circular economy, Celanese and Under Armour are exploring the potential of the fibers to improve the compatibility of stretch fabrics with future recycling systems and infrastructure.

In addition to the sustainability benefits, the new NEOLAST™ fibers deliver increased production precision, allowing spinners to dial power-stretch levels up or down and engineer fibers to meet a broader array of fabric specifications.

Unter dem Titel CLARITY bringt die MUNICH FABRIC START vom 23. bis 25. Januar 2024 Designer, Produktverantwortliche und Modemacher aus ganz Europa zusammen. Flankiert von THE SOURCE, BLUEZONE und dem KEYHOUSE werden rund 1.000 internationale Kollektionen der Saison Frühjahr/Sommer 2025 für die globale Mode- und Bekleidungsindustrie präsentiert.

Abgerundet wird das Angebot durch ein vielfältiges Rahmenprogramm, bestehend aus Keynotes, Podiumsdiskussionen, Trendpräsentationen, Q&A Sessions und mehr mit internationalen Expertinnen und Experten aus den verschiedensten Bereichen der Branche. In den TREND LECTURES (Keyhouse – Halle 5) und der SEMINAR ZONE (BLUEZONE – Halle 7) teilen über 50 Speakerinnen und Speaker in mehr als 30 Vorträgen ihre Expertise, bieten Einblicke in die verschiedensten Bereiche der Branche und klären über neuste Trends und Innovationen auf.

The innovations will be presented by the companies on the first day of the event. All conference participants can vote for one of the six nominees and the top three winners will be honoured with the “Cellulose Fibre Innovation of the Year” award. The Innovation award is sponsored by GIG Karasek (AT).

In addition, the ever-growing sectors of cellulose-based nonwovens, packaging and hygiene products offer conference participants insights beyond the horizon of traditional textile applications. Sustainability and other topics such as fibre-to-fibre recycling and alternative fibre sources are the key topics of the Cellulose Fibres Conference, held in Cologne, Germany, on 13 and 14 March 2024 and online. The conference will showcase the most successful cellulose-based solutions currently on the market or those planned for the near future.

The nominees:

The Straw Flexi-Dress: Design Meets Sustainability – DITF & VRETENA (DE)
The Flexi-Dress design was inspired by the natural golden colour and silky touch of HighPerCell® (HPC) filaments based on unbleached straw pulp. These cellulose filaments are produced using environmentally friendly spinning technology in a closed-loop production process. The design decisions focused on the emotional connection and attachment to the HPC material to create a local and circular fashion product. The Flexi-Dress is designed as a versatile knitted garment – from work to street – that can be worn as a dress, but can also be split into two pieces – used separately as a top and a straight skirt. The top can also be worn with the V-neck front or back. The HPC textile knit structure was considered important for comfort and emotional properties.

HONEXT® Board FR-B (B-s1, d0) – Flame-retardant Board made From Upcycled Fibre Waste From the Paper Industry – Honext Material (ES)
HONEXT® FR-B board (B-s1, d0) is a flame-retardant board made from 100 % upcycled industrial waste fibres from the paper industry. Thanks to innovations in biotechnology, paper sludge is upcycled – the previously “worthless” residue from paper making – to create a fully recyclable material, all without the use of resins. This lightweight and easy-to-handle board boasts high mechanical performance and stability, along with low thermal conductivity, making it perfect for various applications in all interior environments where fire safety is a priority. The material is non-toxic, with no added VOCs, ensuring safety for both people and the planet. A sustainable and healthy material for the built environment, it achieves Cradle-to-Cradle Certified GOLD, and Material Health CertificateTM Gold Level version 4.0 with a carbon-negative footprint. Additionally, it is verified in the Product Environmental Footprint.

LENZING™ Cellulosic Fibres for Glacier Protection – Lenzing (AT)
Glaciers are now facing an unprecedented threat from global warming. Synthetic fibre-based geotextiles, while effective in slowing down glacier melt, create a new environmental challenge: microplastics contaminating glacial environments. The use of such materials contradicts the very purpose of glacier protection, as it exacerbates an already critical environmental problem. Recognizing this problem, the innovative use of cellulosic LENZING™ fibres presents a pioneering solution. The Institute of Ecology, at the University of Innsbruck, together with Lenzing and other partners made first trials in 2022 by covering small test fields with LENZING™ fibre-based geotextiles. The results were promising, confirming the effectiveness of this approach in slowing glacier melt without leaving behind microplastic.

The RENU Jacket – Advanced Recycling for Cellulosic Textiles – Pangaia (UK) & Evrnu (US)
PANGAIA LAB was born out of a dream to reduce barriers between people and the breakthrough innovations in material science. In 2023, PANGAIA LAB launched the RENU Jacket, a limited edition product made from 100% Nucycl® – a technology that recycles cellulosic textiles by breaking them down to their molecular building blocks, and reforming them into new fibres. This process produces a result that is 100% recycled and 100% recyclable when returned to the correct waste stream – maintaining the strength of the fibre so it doesn’t need to be blended with virgin material.
Through collaboration with Evrnu, the PANGAIA team created the world’s first 100% chemically recycled denim jacket, replacing a material traditionally made from 100% virgin cotton. By incorporating Nucycl® into this iconic fabric construction, dyed with natural indigo, the teams have demonstrated that it’s possible to replace ubiquitous materials with this innovation.

Textiles Made from Easy-to-dye Biocelsol – VTT Technical Research Centre of Finland (FI)
One third of the textile industry’s wastewater is generated in dyeing and one fifth in finishing. But the use of chemically modified Biocelsol fibres reduces waste water. The knitted fabric is made from viscose and Biocelsol fibres and is only dyed after knitting. This gives the Biocelsol fibres a darker shade, using the same amount of dye and no salt in dyeing process. In addition, an interesting visual effect can be achieved. Moreover, less dye is needed for the darker colour tone in the finished textile and the possibility to use the salt-free dyeing is more environmentally friendly.
These special properties of man-made cellulosic fibres will reassert the fibres as a replacement for the existing fossil-based fibres, thus filling the demand for more environmentally friendly dyeing-solutions in the textile industry. The functionalised Biocelsol fibres were made in Finnish Academy FinnCERES project and are produced by wet spinning technique from the cellulose dope containing low amounts of 3-allyloxy-2-hydroxypropyl substituents. The functionality formed is permanent and has been shown to significantly improve the dyeability of the fibres. In addition, the functionalisation of Biocelsol fibres reduces the cost of textile finishing and dyeing as well as the effluent load.

A New Generation of Bio-based and Resource-efficient Fibre – TreeToTextile (SE)
TreeToTextile has developed a unique, sustainable and resource efficient fibre that doesn't exist on the market today. It has a natural dry feel similar to cotton and a semi-dull sheen and high drape like viscose. It is based on cellulose and has the potential to complement or replace cotton, viscose and polyester as a single fibre or in blends, depending on the application.
TreeToTextile Technology™ has a low demand for chemicals, energy and water. According to a third party verified LCA, the TreeToTextile fibre has a climate impact of 0.6 kg CO2 eq/kilo fibre. The fibre is made from bio-based and traceable resources and is biodegradable.
