From the Sector

CELLIANT® with REPREVE®, introduced by Hologenix with global textile solutions provider UNIFI®, makers of REPREVE®, has been awarded a Top 5 Selection in the Accelerated Eco category of the Spring/Summer ISPO Textrends 2025 Awards.

Last fall CELLIANT with REPREVE was also awarded a Selection in the Fibers & Insulation Category of the ISPO Textrends Fall/Winter 2024/2025. In addition, in the spring the fiber was shortlisted in the Drapers Sustainable Fashion 2023 Awards in the Sustainable Textile Innovation category.

Twice a year, ISPO recognizes innovative fibers, fabrics and components that are used to manufacture sports apparel. Both companies are excited that this innovation, whereby CELLIANT infrared (IR) technology is embedded into REPREVE, a brand of recycled fiber, has achieved these honors. CELLIANT with REPREVE is a performance fiber made from recycled materials that have been enhanced with IR technology to provide wellness benefits to the consumer.  

CELLIANT is a natural blend of IR-generating bioceramic minerals, which, when embedded into textiles, allows them to convert body heat into infrared energy, returning it to the body and temporarily increasing local circulation and cellular oxygenation. This aids in muscle recovery, increases endurance, and improves overall performance in healthy individuals, among other benefits.
 
REPREVE recycled performance fiber consists of high-quality fibers made from 100% recycled materials, including post-consumer plastic bottles and pre-consumer waste. It is also certified and traceable with UNIFI’s U TRUST® verification and FiberPrint™ technology, which provide assurance that the product comes from recycled materials. Compared to virgin fiber, REPREVE helps to offset the use of petroleum, conserving water and energy and emitting fewer greenhouse gasses.

This award marks the third year in a row that Hologenix has had its CELLIANT technology recognized in the ISPO Textrends Awards. CELLIANT in pure white was a Top Ten Winner in 2022. The prior year, CELLIANT Viscose was a Selection Winner as well. 

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.

Freudenberg Performance Materials Apparel (Freudenberg) launches its biodegradable fusible cotton shirt interlinings range 46xx. With this innovation, the world’s leading specialist in woven, knitted, weft and nonwoven interlinings reduces its impact on the environment and supports customers in achieving their own sustainability objectives. In Asia, the series is marketed under the name 42xx series.

Approved biodegradability and non-toxicity by Hohenstein Laboratories
The new Freudenberg fusible interlinings for shirts and blouses have been developed in such a way that they are harmless to people and the environment at the end of their life cycle. Germany’s independent Hohenstein Laboratories performed biodegradation tests on the 46xx series, based on the Hohenstein method which draws on DIN EN ISO 11721-2:2003 and EN ISO 846, and approved it as biodegradable and ecotoxicologically harmless. The tests by Hohenstein showed no negative effects on either the germination of garden cress nor on earthworms in the acute toxicity test.

Energy-saving interlining
The new biodegradable shirt interlinings also show great potential for energy saving, as the fusing can be performed at a low temperature. Concretely, this means that the resulting temperature between the upper fabric and the shirt interlining during fusing is only 127°C which is significantly lower than the commonly used temperature of 143°C. Certified to OEKO-TEX® STANDARD 100 Class II for successfully testing for no harmful substances, the shirt interlinings are washable at up to 40°C and resistant to dry cleaning. In addition, it has also passed all ecological-toxicological tests and is a perfect end-of-life cycle solution.

Product details and availability
The products in range 46xx are available in Europe in the color white and the following weight classes: 4605 (90g/m2), 4616 (150g/m2) and 4618 (55g/m2). The adhesive of the interlinings consists of a 100% degradable bio-polymer. The shirt interlinings are ideal for reinforcing shirt and blouse collars, cuffs and plackets used in fashion, leisure and business clothing. The biodegradable, non-toxic interlinings are particularly important for labels with an ecologically sustainable claim.

Viscose speciality fibre manufacturer Kelheim Fibres, nonwoven producer Sandler, and hygiene product manufacturer pelzGROUP have jointly developed a new panty liner that is plastic-free according to the European Single-Use Plastics Directive (SUPD). This innovative solution is a step towards reducing the amount of plastic in hygiene products – and thus also a contribution to tackling the problem of plastic pollution.

According to a UNEP study on marine litter and microplastics, eight million tons of plastic end up in the oceans every year. A significant portion of this pollution comes from single-use plastic products, including conventional period products such as pads or panty liners.

The partnership between the three companies was formed under the Open Innovation principle, which allowed for creative idea exchange and facilitated the development of an innovative product. According to Jessica Zeitler, R&D Specialist at Sandler, “Our collaboration with Kelheim Fibres and pelzGROUP is a great example of how companies can work together to create solutions that benefit both the environment and consumers. We are proud to be part of this project and the opportunities it offers.”

For hygiene product manufacturer pelzGROUP, it is important to combine sustainability and performance to achieve broad acceptance in the market. “Our panty liner meets the strict requirements of the European Single-Use Plastics Directive (SUPD) while also matching the performance of conventional synthetic products. At the same time, our new panty liner has a completely European supply chain. This means short distances and therefore low CO2 emissions, and – especially in times of global disruption – reliability for our customers,” emphasizes Dr. Henning Röttger, Head of Business Development at pelzGROUP.

"Our viscose speciality fibres are an environmentally friendly and high-performance alternative to synthetic materials," says Dominik Mayer, Project Manager Fibre & Application Development at Kelheim Fibres. "They are at the very beginning of the product value chain and yet have an enormous impact on the functionality of the end product. Open innovation allows us to bring all partners in the value chain to the table, to find the best solution together in a very short time and bring it to commercialisation - the collaboration with Sandler and pelzGROUP is an important milestone in our AHP journey."

Freudenberg Performance Materials Apparel is expanding its Super Elastic Interlinings Range with the introduction of the apparel industry’s first 100% recycled thermoplastic elastomers (rTPE) base content interlining series. In recognition of the growing use of elastic interlinings in apparel and building on the principles of Freudenberg Performance Materials´ Apparel’s House of Sustainability, these new products speak for high-quality and sustainable solutions.

The new, 100% rTPE base content interlinings are offered in 40-90 g/m2 weights, with wide applicability – from lightweight knit fabrics with applications in leggings and sports bras to elastic woven fabrics that require medium-to-heavy weights, such as denim, maternity clothes, or casual wear. Sustainable without compromising on quality, the new interlinings offer exceptional elasticity and retain excellent recovery capabilities.

The 100% rTPE base content interlinings reduce the need for virgin materials in apparel while also reducing the demand for the extractive practices necessary to produce such materials. Furthermore, the use of recycled components reduces materials in landfills and oceans, in consideration of full-garment lifecycle management.

Textile performance inspired by nature - Swiss textile manufacturer Schoeller Textil AG launches the sustainable textile collection RE-SOURCE as part of its brand sustainability strategy. All textile innovations in the collection are made from bio-based, post- as well as pre-consumer materials such as recycled polyester and spandex. These are further enhanced with Schoeller textile technologies to provide the wearer with breathability, thermal regulation and wind and water repellency.

Two textile innovations in the collection have been lined on the inside with natural NATIVA Merino wool, produced under the highest sustainability standards. The manufacturing process of NATIVA Merino wool is 100% transparent and traceable for consumers through blockchain technology. NATIVA farms worldwide meet strict social and environmental requirements for animal welfare (ban on mulesing), land management and ethical labour guidelines.

Schoeller is committed to the CODE OF CONDUCT, which guarantees transparent production chains, environmental protection and fair working conditions. All RE-SOURCE textile innovations are bluesign approved - the international standard for responsible and sustainable textile manufacturing.

"The special Q-cycle process was used for RE-SOURCE. The resistant and durable Q-cycle polyamide is obtained by pyrolysis of used tyres and thus saves Co2 emissions compared to the combustion process. In this way, we are helping to protect the climate with Q-cycle," says Hans Kohn, COO, Schoeller Technologies AG.

The new recycled textile collection will be presented at the PERFORMANCE DAYS textile trade fair in Munich from 15-16 March 2023.

Kelheim Fibres, a leading manufacturer of viscose speciality fibres, has joined Recycling Atelier Augsburg. Recycling Atelier Augsburg is a unique centre for research and development in the field of textile recycling. It is located at the Institut für Textiltechnik Augsburg an affiliated institute of Augsburg University of Applied Sciences. The two institutions founded the Recycling Atelier in June 2022 together with twelve partners from the German textile industry.

In the Recycling Atelier, the focus is on the triad of technical and ecological sense as well as economic benefit. In this way, the partners of the Recycling Atelier are standing up against fast fashion, outsourced corporate responsibility and a general decline in raw material quality, which often fuels downcycling - the low-quality reuse - of materials.

As a model factory, the Recycling Atelier Augsburg combines the most important processes of textile recycling and offers holistic and comprehensive research along the value chain," explains Georg Stegschuster, head of the Recycling Atelier Augsburg. The scientists research on all process steps of textile recycling: from material analysis to sorting, preparation and textile processing to sustainable product design. Comprehensive data collection and the use of artificial intelligence as well as innovative materials play a central role.

Kelheim Fibres is a producer of high-quality viscose fibres, which consist of cellulose, the main component of the renewable raw material wood, and are used worldwide for products in areas such as hygiene, textiles, and technical applications.

"In New Business Development as well as Fibre and Application Development, we follow the Open Innovation concept - the cooperation with the Recycling Atelier offers us an ideal platform for this. Here we work with partners to advance sustainability and performance," explains Maik Thiel, project manager at Kelheim Fibres.

Recycled cotton fibres are often very short or of uneven length, which makes further processing of 100 % recycled material a challenge. Adding speciality fibres from Kelheim Fibres should enable the production of high-quality new products, such as nonwovens. In the future, the fibres provided by Kelheim Fibres will also be made from recycled pulp.

Kelheim Fibres and SUMO are presenting their high-performance absorbent pads for the reusable Sumo diaper at this year's Cellulose Fibres Conference. The Sumo diaper is a sustainable and washable cloth diaper made entirely from biobased materials, offering high performance and innovative design.

The Sumo diaper offers a reusable alternative, consisting of a waterproof shell and absorbent pads. To enhance the performance of the pads, Sumo collaborated with Kelheim Fibres, a leading viscose specialty fibre manufacturer with decades of experience in the hygiene sector.

Together with the Saxon Textile Research Institute STFI, Sumo and Kelheim Fibres have developed a high-performance absorbent pad that is free of fossil-based materials and has already been awarded the Techtextil Innovation Award. The basis for the innovative construction are Kelheim's functionalized specialty viscose fibres with modified cross-sections, which ensure particularly high absorbency and extremely low rewet values.

To ensure the washability of the product, needle-punched/thermally bonded nonwovens were chosen, consisting of a mixture of specialty viscose and PLA bicomponent fibres. By combining nonwovens, typically used in single-use applications, with reusable products, the partners have chosen a new approach.

Natalie Wunder, project manager at Kelheim Fibres, and Luisa Kahlfeldt, founder and designer of SUMO, explain in their joint presentation at the Cellulose Fibre Conference how open innovation has led to successful development collaboration, how this response to current consumer needs has emerged, and what steps are planned for the future.

• Iconic 200 Series fleece to be the first fabric made from this new process.

Polartec®, a Milliken & Company brand, announces Polartec® Shed Less Fleece, a new milestone in its industry-leading efforts to reduce textile fiber fragment shedding. Shed Less is a process that combines yarn construction, knitting, chemistry, and manufacturing to reduce home laundry fiber fragment shedding by an average of 85%. The first fabric to receive this new technology is the brand’s iconic Polartec® 200 Series Fleece, the modern version of the original PolarFleece® launched in 1981, and in 1993, the first performance fleece knit from yarn made from recycled plastic bottles.

The Shed Less process works by engineering the lofted fibers that give fleece its soft hand the ability to resist breaking and rubbing off during home laundering, cited as one contributing factor to the spread of fibers fragments (commonly referred to as microfibers). Polartec® Shed Less Fleece achieves this while maintaining all of the attributes that continue to make Polartec fleece a staple of midlayer collections - lightweight, breathable and warm.

The brand used the AATCC (American Association of Textile Chemists and Colorists) TM212-2021 test method for fiber fragment release during home laundering. This test was conducted with large sample sizes to account for variability. The testing concluded that Shed Less Fleece reduced fiber fragment shedding by an average of 85% compared to the baseline fabric.

“In 2016 we began looking into how we might test for fiber loss because there wasn’t a lot of research on the issue.” said Aimee LaValley, Polartec Textile Development, Dye and Chemistry Manager. “This led to new products like Polartec Power Air™, new manufacturing processes, as well as our participation in the TextileMission workgroup to study the issue on an interdisciplinary basis.”

TextileMission was a three year collaborative initiative of academia and industry to reduce the impact of textile microplastics funded by the German Federal Ministry of Education and Research. Founding partners include The Association of the German Sporting Goods Industry, Hochschule Niederrhein - University of Applied Science; TU Dresden - Institute of Water Chemistry; Vaude Sport; WWF Germany; Adidas AG; Henkel AG; Miele & CIE; and Polartec, LLC.

Polartec® Shed Less Fleece will be initially launched in the United States and will be available to customers beginning March 1, 2023. The brand plans to apply the Shed Less process to many other industry-leading fabric platforms and manufacturing facilities around the world.
