From the Sector

Freudenberg Performance Materials (Freudenberg) has launched an elastic variant of its flexible superabsorbers for modern wound dressings. These superabsorbers increase the comfort level for patients as well as enabling longer wear time, thus reducing the frequency of dressing changes. Freudenberg is debuting the elastic superabsorbers at this year’s Compamed in Düsseldorf, from November 14 – 17, 2022. Further highlights at the trade fair include components for more sustainable wound care, PU foams with directly applied silicone adhesives, and an innovative hydrophilic debridement foam.

Freudenberg uses a new technology to manufacture the elastic superabsorbers. Unlike other methods, this technology does not perforate or slit the material, thus achieving a high degree of consistent elasticity. Furthermore, the technology used by Freudenberg bonds the superabsorbent fibers more uniformly with the material, thus enhancing the integrity of this layer in the wound dressing.

“Our new elastic superabsorbers demonstrate yet again how Freudenberg components help increase comfort for patients, reduce the workload for nursing staff and lower healthcare costs. Our extensive technology platform and our innovative strength are the basis for this,” Dr. Henk Randau, SVP and General Manager Global Division Healthcare at Freudenberg Performance Materials, said.

The vision of the OEKO-TEX® Association, which was founded in March 1992 through a partnership between the Hohenstein Research Institute and the Austrian Textile Research Institute (OETI), is still reflected today in the organization's core values: trust, safety, and sustainability. For three decades, OEKO-TEX® has pursued the goal of building trust for companies and consumers and enabling them to make responsible decisions to protect people and the planet. "Our services bring transparency to the international textile and leather industry supply chains," says OEKO-TEX® Secretary General Georg Dieners. "They enable all stakeholders to make mindful decisions that help preserve our planet for future generations."

OEKO-TEX® market leadership
In 1992, 20 years before the United Nations announced the Sustainable Development Goals (SDGs), OEKO-TEX® launched STANDARD 100 by OEKO-TEX®, now one of the best-known labels for product safety.
"It emerged from the Schadstoffgeprüft nach ÖTN 100(tested for harmful substances according to ÖTN 100), developed by OETI in 1989 to address increasing public interest in textile ecology and health," the Austrian Textile Research Institute reminds us. The limit values and test methods on which STANDARD 100 by OEKO-TEX® is based were internationally standardized and are adapted to the latest scientific findings and legislation at least once a year - a principle that is applied to all OEKO-TEX® standards. Prof. Dr. Stefan Mecheels, the owner of the textile testing service provider Hohenstein, adds: "From the very beginning, we have considered the needs of all players in the textile value chain and continue to create solutions for current and future market requirements."

At least seven SDGs are firmly integrated into the OEKO-TEX® product portfolio. For example, Good Health & Well-Being (SDG 3) and Clean Water & Sanitation (SDG 6) are reflected in the STeP by OEKO-TEX® factory certification, and Responsible Consumption & Production (SDG 12) and Climate Action (SDG 13) are implemented through the comprehensive MADE IN GREEN by OEKO-TEX® product label.

Today, the international association consists of 17 independent research and testing institutes focused on textile and leather, with contact offices in over 60 countries. They are responsible for the joint development of the test methods and limit values in the OEKO-TEX® Standards and carry out laboratory tests and factory audits according to globally uniform specifications. These comprehensive product and process audits to ensure appropriate risk management, consumer and environmental protection, and legal compliance. With their wide-ranging research and development, the accredited OEKO-TEX® test institutes provide important insight for innovations within the textile and leather industry. They work in close cooperation with manufacturers and make a significant contribution to the development of high-quality textile and leather products at all stages of the value chain.

Mirror of social and political development
Being close to the market, and ideally, one step ahead is essential to supporting companies who are adapting to constantly changing conditions and meeting consumer expectations. Therefore, the development of OEKO-TEX® is not only a reflection of scientific knowledge but also of social and political trends. The focus is always on standardizing sustainable action and measures and making it easier for the industry to quickly and comprehensively implement sustainability goals.

Exchange with third parties is particularly valuable for this purpose. OEKO-TEX® participates in various international multi-stakeholder initiatives such as the Organization for Economic Co-operation and Development (OECD), the Partnership for Sustainable Textiles, the ZHDC (Zero Discharge of Hazardous Chemicals), and Greenpeace.
In addition to cooperation with external multi-stakeholder initiatives, the OEKO-TEX® International Advisory Board (IAB) meets annually. The core function of the IAB is to help review consistent and market-oriented Standards development proposals by the OEKO-TEX® Working Groups. In addition, OEKO-TEX® is conducting a public stakeholder consultation to gain further insights from all interest groups, which it will integrate into further development of the Standards.
Using three decades of experience for the future
The founding goal of enabling responsible choices that preserve our planet for future generations has become increasingly urgent over the past 30 years. So, OEKO-TEX® is even more resolute than ever in developing comprehensive solutions. We stand by industry and consumers as a trusted partner for the challenges ahead. In addition to the IMPACT CALCULATOR launched in January 2022, which helps STeP by OEKO-TEX® certified production facilities reduce their carbon emissions and water consumption, this summer, the association will launch a service to help companies transition to the upcoming Due Diligence Laws.

Archroma announced the launch of EARTH SOFT, a new softening system for textile and fashion applications, based on Archroma's latest innovation, a vegan silicone softener, Siligen® EH1, with 35% plant-based active content.

Siligen® EH1 is the latest addition in the plant-based innovations developed by Archroma in recent years, such as EarthColors® dyes and Appretan® NTR binders, as alternatives offered to manufacturers and brands looking to reduce the use of fossil fuel based ingredients without compromising performance.

The range has been developed in line with the principles of “The Archroma Way to a sustainable world: safe, efficient, enhanced, it’s our nature”. More than 35% of the Siligen® EH1 softener's active content is based on plant-based, renewable raw materials. In addition, the product features ultralow cyclic siloxanes (D4, D5, D6) which are classified by the European Chemicals Agency as “Substances of Very High Concern” due to their very persistent and bioaccumulative properties.

Siligen® EH1 is ideally suited for shirts, underwear, sportswear, towels, bed sheets, etc. as it provides an excellent wearing comfort by supporting a good moisture transportation and delivering a smooth and soft touch.

The new softener, and the EARTH SOFT system which also includes a Hydroperm® wicking agent to boost hydrophilic properties on synthetic and blended fibers, can be applied on all natural and synthetic textile fibers.

Siligen® EH1 is suitable for both woven and knitted articles. It can be applied by padding process, as well as by exhaust process as it shows a very good shear stability and a low foaming profile. It can be used on white articles and those treated with optical brighteners, as it doesn’t cause thermomigration nor phenolic yellowing.

Paul Cowell, Head of Competence Centers for Brand & Performance Textile Specialties at Archroma, comments: “The new EARTH SOFT system based on Siligen® EH1 softener adds to our growing portfolio of innovations based on natural and renewable plant-based resources. This new breakthrough innovation by Archroma helps us and our partners in the textile and fashion industry to minimize our dependence on petroleum fossil fuel products.”

Microplastic pollution is a global challenge across many industries and sectors – one of critical importance being textiles.

A 2021 study by the California Ocean Science Trust and a group of interdisciplinary scientists acknowledges that microfibres from textiles are among the most common microplastic materials found in the marine environment. Every time synthetic clothes are manufactured, worn, washed, or disposed of, they release microplastics into terrestrial and marine environments, including human food chains. Synthetic fibres represent over two-thirds (69%) of all materials used in textiles, a proportion that is expected to rise to 73% by 2030. The production of synthetic fibres has fuelled a 40-year trend of increased per capita clothing consumption.

Global textile consumption has become:

• more reliant on non-renewable resources,
• less biodegradable, and
• increasingly prone to releasing microplastics.

The increased consumption is also discretionary, driven by consumer desire and remains unchecked. Thus, the long-term trend in the textile industry parallels the intentional addition of microplastics to products such as cosmetics. The contrast is that the European Chemicals Agency (ECHA) has recommended such intentional additions be restricted, whereas the over-consumption of synthetic fibres continues unchecked. One way for the EU to account for and mitigate microplastic pollution is through an EU-backed methodology measuring and reporting microplastic emissions, so that consumers and procurement officers have the information needed to minimise microplastic pollution resulting from their purchasing decisions.

There is a critical opportunity to address microplastic pollution in the fashion textile industry through the EU Product Environmental Footprint (PEF) methodology. To meet the environmental objectives of the Circular Economy Action Plan, the EU is proposing that companies substantiate their products’ environmental credentials using this harmonised methodology. However, microplastic pollution is not accounted for in the PEF methodology. This omission has the effect of assigning a zero score to microplastic pollution and would undermine the efforts of the European Green Deal, which aim “to address the unintentional release of microplastics in the environment.”

The incorporation of microplastic pollution as an indicator would increase the legitimacy of the PEF method as well as better inform consumer purchasing decisions, especially as the European Green Deal seeks to “further develop and harmonise methods for measuring unintentionally released microplastics, especially from tyres and textiles, and delivering harmonised data on microplastics concentrations in seawater.”

Whilst we continue to learn about the damage of microplastics and there is new knowledge emerging on the toxic impacts along the food chain, there is sufficient information on the rate of microplastic leakage into the environment to implement a basic, inventory level indicator in the PEF now. This is consistent with the recommendations of a review of microplastic pollution originating from the life cycle of apparel and home textiles. There are precedents in PEF for basic level (e.g., ‘resource use, fossils’) and largely untested (e.g. land occupation and toxicity indicators) indicators, and therefore an opportunity for the EU to promote research and development in the measurement and modelling of microplastic pollution by including such emissions in the PEF methodology. For such an indicator, the long and complex supply chains of the apparel and footwear industry would be a test case with high-impact and a global reach.

Huntsman Textile Effects is bringing its complete end-to-end suite of high-performance solutions for sports apparel to Performance Days Digital Fair from December 1 to 2, 2021 virtually.

Driven by growing consumer interest in active and healthy lifestyles, coupled with the growing number of national sports participation programs that promote healthy living, the global sportwear market shows no signs of slowing. Brands that aim to satisfy this high-growth market need to be able to produce performance apparel that not only delivers sought-after functional capabilities and desirable aesthetics, but also comes with low environmental impact.

Huntsman will introduce the latest addition to the third generation of its revolutionary AVITERA® SE polyreactive dye range at Performance Days. AVITERA® ROSE SE delivers bluish-red shades while reducing the water and energy required for production by up to 50% and increasing mill output by up to 25% or more. It also significantly outperforms available dyeing technologies for cellulosic fibers and blends in terms of value, reducing recipe costs, minimizing processing costs and eliminating reprocessing.

Also in the spotlight are eco-friendly solutions for the challenges of achieving full whites and consistent shades on recycled polyester (rPET) with right-first-time quality. Huntsman’s rPET processing solutions include pre-treatment chemicals, fluorescent whitening agents, state-of-the-art washfast dyes, and finishing solutions for high-performance protection and comfort.

In partnership with Sciessent, Huntsman is also bringing revolutionary antimicrobial and odor-control solutions to Performance Days. These include Sciessent’s Agion Active® X2, a next-generation odor-control solution that combines advanced technologies to both capture and fight odor-causing bacteria for garments that smell fresh for longer and need less frequent washing. The partners are also previewing a new solution: Sciessent’s NOBO™, a cost-effective odor adsorber that provides odor control on virtually any fabric.

Other featured innovations include Teflon Eco Dry with Zelan™ R2 Plus technology. A breakthrough in sustainable water repellency, it contains 30% renewably sourced plant-based raw materials and meets or exceeds performance levels possible with traditional fluorinated technologies. Another exciting Huntsman solution is the new PHOBOL® Extender UXN – a product that optimizes water-repellent finishes for long-lasting fabric protection. It is free from butanone oxime, which has recently been re-classified in Europe and restricted above certain limits in products by bluesign®.

Kai-Chieh Kuo, PhD student at the Institut für Textiltechnik (ITA) of RWTH Aachen University, was awarded the German Textile Mechanical Engineering 2021 Best Master's Thesis Award for his master's thesis entitled "Modification of the tube weaving process of fine yarns for the production of woven ultra-low profile stent grafts". The prize is endowed with 3,500€. Peter D. Dornier, Chairman of the Board of the Walter Reiners-Stiftung (Foundation), virtually presented the award on the occasion of the ADD International Textile Conference on 9 November 2021.

Minimally invasive endovascular aortic repair (EVAR) with textile stent-graft systems is nowadays a clinically established therapy procedure for the treatment of abdominal aortic aneurysms (AAA) – pathological bulges of the aorta. Due to the thick profile of the folded stent graft systems, there is currently a high risk of injuring narrowed or highly angulated access vessels from the inside during implantation. Stent graft systems with smaller profiles could provide an improvement, which could overcome complicated access routes through a lower bending stiffness. One possible approach for reducing the system profiles is the use of thin-walled tubular woven fabrics made of ultrafine multifilament yarns (≤20 dtex) as graft material.

Up to now, it has not been possible to process the fine yarns with the required high thread density (>200 threads/cm) and the available weaving technology in order to guarantee sufficient tightness against blood.

In his master's thesis, Kai-Chieh Kuo made high-density tubular weaving of ultra-fine filament yarns possible for the first time by means of suitable modifications to a shuttle loom as well as adaptations in the weaving preparation. In particular, he developed a new innovative reed technology that reduces warp thread friction during the shedding process and thus improves the process stability of the dense tube weaving process of fine yarns.

With the help of the process modification, it was then possible to produce high-density, thin-walled tubular woven fabrics, which were positively evaluated with regard to their suitability for a stent graft. Above all the potential of these tubular fabrics lies in their extremely thin-walled fabric profile, which seals well against blood. By using these new types of tubular fabrics as graft material for stent grafts, the system profile of the folded stent graft system can be reduced without having to compromise the blood tightness of the implant. The technology developed by Mr Kuo is not only applicable to stent graft systems, but also offers great possibilities for use in all other endovascular implants such as trans catheter heart valves, covered stents and small-lumen vascular prostheses.

Reifenhäuser Enka Tecnica will exhibit its wide range of replacement components for spunbond, meltblown, and composite lines at the world's leading nonwovens trade show INDEX in Geneva from October 19 to 22, 2021. The highly specialized custom manufacturer offers high-end technology "Made in Germany" that is 100% compatible with all globally installed lines.

Producers of nonwovens worldwide rely on Enka Tecnica components to manufacture products for complex applications in hygiene, medical or filtration to provide them with access to new profitable markets. Trade-show visitors will gain a detailed insight into the entire range of products, from meltblown and spunbond spinnerets to meltblown cassettes and complete meltblown spinning beams designed with an energy concept optimized for sustainability. The tips and capillaries assure consistent product quality and precision, allowing producers to meet their tolerance specifications reliably and avoid scrap at the same time..

With its refresh service for refurbishing used components, Enka Tecnica not only offers a cost-efficient alternative to new parts, but also extremely fast delivery times, a factor that is often decisive to maintain daily production targets. Visitors to Geneva will be able to see the quality of refresh components displayed at the booth - a meltblown and a spunbond spinneret, half of which has been refurbished. They will be able to see the condition of the capillary holes before and after the refresh through a microscope.

Another trade show highlight includes jet strips for hydroentangling nonwovens. Depending on the application, they are offered in Smart, Advanced, and Premium versions and have a special unique selling point – the strips are fully hardened, whereas competitor products usually only have a hardened surface. This quality advantage results in significantly longer service lives, which is why they are also known on the market as "The World's Hardest Strips”.

Double the production rate, with lower energy consumption per kilogram of fiber material – that might sound like a contradiction, but the new Trützschler pre-cleaner CL-X makes it possible. It gently and reliably removes coarse contaminants like leaf debris, stalks or seeds from cotton with minimum loss of good fibers. The pre-cleaner CL-X provides more efficiency and lays the foundation for a high-quality end-product before the cotton is further processed in mixers and fine cleaners.

Sappi offers Transjet Tacky Industrial, a coated dye sublimation paper for digital transfer printing, specially developed for high-speed inkjet printing on highly elastic textiles. Also new is the uncoated dye sublimation paper Basejet, which has been developed for light designs for high-speed digital printing of fashion and home textiles.

• Transjet Tacky Industrial: Immediate tack effect, high ink transfer, fast ink drying; no ghosting on elastic textiles thanks to reversible tack
• Basejet: Consistent print quality for light designs, fast ink-drying, very fast transfer process

Transjet Tacky Industrial enables highly elastic fabrics to be printed on industrial high-speed machines that work with a higher glycol content, such as printheads from Kyocera. The paper is first printed with the desired image or pattern which is then transferred to the elastic polyester fabric by means of heat and pressure.

Sublimation paper for the textile industry
The new dye sublimation paper offers many benefits for the textile industry, which frequently has to adapt to changing trends. As it is suitable for use on high-speed digital printers, significantly more designs can be printed in the same time than was previously possible on plotters. Thanks to a special heat-reactive coating, the paper adheres to highly stretchable content, while the reversible tack prevents ghosting and textile shrinkage. Transjet Tacky
Industrial has a high ink load capacity so the print can be better accentuated due to strong colour saturation. The design remains clearly visible when the fabric is stretched to its maximum, which is often the case with sportswear in particular.

Basejet specially for light designs
Sappi has also added the Basejet uncoated dye sublimation paper to its portfolio, an additional solution for the digital printing of fashion and home textiles in consistent print quality. The uncoated dye sublimation paper is intended in particular for light designs and cost-driven production processes.
