From the Sector

Royal DSM, a global science-based company in Nutrition, Health and Sustainable Living, announced that, together with armor manufacturing partner, MKU Ltd, has provided next generation armor technology with Dyneema® unidirectional (UD) material to support the Sao Paulo police.

The Sao Paulo police, which is comprised of more than 100,000 officers, is the first law enforcement agency in Brazil to initiate a tender for personal protective equipment based on the latest National Institute of Justice (NIJ) .06 standards for body armor, which provide comprehensive and rigorous compliance for the performance and testing of ballistic materials. In addition to NIJ .06 certification, the tender set extremely lightweight requirements for level IIIA soft armor vests.

The hybrid vest solution developed MKU, a global leader in defense and homeland security solutions, for the Sao Paulo police utilizes predominantly Dyneema® UD material to reach new levels of performance and protection while simultaneously enhancing user comfort and mobility. Dyneema®, a strong and light fiber, is the one of leading global brands for ultra-high molecular weight polyethylene (UHMwPE) fiber, UD and fabrics, offering ballistic solutions for personal and vehicle armor that combine maximum strength with minimum weight.

In soft armor applications, Dyneema® offers up to 35 percent weight reduction when compared to competitive materials, while still protecting against both legacy and emerging threats.

In addition to the lightweight armor requirement, the vests were also thoroughly tested to ensure performance with NIJ ballistic reports, NIJ certification and in-house ballistic testing both during the tender process and after the vests were received.

In line with DSM’s commitment to protect people and the environment they live in, one of the world’s first ever bio-based HMPE fibers was introduced in 2020.

• Swiss weaving machinery manufacturers are in the forefront of novel application development

Shoes and electronic calculators are probably not the first products people would associate with the textile weaving process. But they certainly signpost the future for woven fabrics, as two examples of the ever-wider possibilities of latest technology in the field. Fashion and function already combine in the increasing popularity of woven fabrics for shoes, and this is a present and future trend. Calculators in fabrics? That’s another story of ingenious development, using so-called ‘meander fields’ on the back and keys printed on the front of the material.

These glimpses of the outlook for modern weavers are among the highlights of developments now being pioneered by Swiss textile machinery companies. All weaving markets require innovation, as well as speed, efficiency, quality and sustainability. Member firms of the Swiss Textile Machinery Association respond to these needs at every point in the process – from tightening the first thread in the warp to winding the last inch for fabric delivery. They also share a common advantage, with a leading position in the traditional weaving industry as well as the expertise to foster new and exciting applications.

Technology and research cooperation
The concept of a ‘textile calculator’ was developed by Jakob Müller Group, in cooperation with the textile research institute Thuringen-Vogtland. Müller’s patented MDW® multi-directional weaving technology is able to create the meander fields which allow calculator functions to be accessed at a touch. A novel and useful facility, which suggests limitless expansion.

Today, the latest woven shoes are appreciated for their precise and comfortable fit. They score through their durability, strength and stability, meeting the requirements of individual athletes across many sports, as well as leisurewear. Stäubli is well known as a leading global specialist in weaving preparation, shedding systems and high-speed textile machinery. Its jacquard machines offer great flexibility across a wide range of formats, weaving all types of technical textiles, lightweight reinforcement fabrics – and shoes.

It’s possible to weave new materials such as ceramics, mix fibers such as aramid, carbon and other, and produce innovative multi-layers with variable thicknesses. Such applications put special demands on weaving machines which are fulfilled by Stäubli high-performance TF weaving systems.

Great weaving results are impossible without perfect warp tension, now available thanks to the world-leading electronic warp feeding systems of Crealet. Some market segments in weaving industry today demand warp let-off systems which meet individual customer requirements. For example, the company has recognized expertise to understand that geotextile products often need special treatment, as provided by its intelligent warp tension control system. Individual and connective solutions are designed to allow external support via remote link. Crealet’s warp let-off systems are widely used in both ribbon and broadloom weaving, for technical textiles applied on single or multiple warp beams and creels.

Functional, sustainable, automated
Trends in the field of woven narrow fabrics are clearly focused on functionality and sustainability. The Jakob Müller Group has already embraced these principles – for example using natural fibers for 100% recyclable labels with a soft-feel selvedge. It also focuses as much as possible on the processing of recycled, synthetic materials. Both PET bottles and polyester waste from production are recycled and processed into elastic and rigid tapes for the apparel industry.

For efficient fabric production environments, it is now recognized that automated quality solutions are essential. Quality standards are increasing everywhere and zero-defect levels are mandatory for sensitive applications such as airbags and protective apparel.

Uster’s latest generation of on-loom monitoring and inspection systems offers real operational improvements for weavers. The fabric quality monitoring prevents waste, while the quality assurance system significantly improves first-quality yield for all applications. Protecting fabric makers from costly claims and damaged reputations, automated fabric inspection also removes the need for slow, costly and unreliable manual inspection, freeing operators to focus on higher-skilled jobs.

Smart and collaborative robotics (cobots) offer many automation possibilities in weaving rooms. Stäubli’s future oriented robotics division is a driver in this segment with first effective installations in warp and creel preparation.

Control and productivity
Willy Grob’s specialized solutions for woven fabric winding focus on reliable control of tension, keeping it constant from the start of the process right through to the full cloth roll. Continuous digital control is especially important for sensitive fabrics, while performance and productivity are also critical advantages. In this regard, the company’s large-scale batching units can provide ten times the winding capacity of a regular winder integrated in the weaving machine.

The customized concept by Grob as well as design and implementation result in great flexibility and functionality of the fabric winding equipment – yet another example of Swiss ingenuity in textile machinery.  
There is even more innovation to come in weaving – and in other segments – from members of the Swiss Textile Machinery Association in future! This confident assertion is founded on an impressive statistic: the 4077 years of experience behind the creative power of the association’s member firms. It’s proof positive that their developments grow out of profound knowledge and continuous research.

• BIONIC-FINISH®ECO Fluorine-Free, Water Repellent Finishes for Ultimate Performance

In recent years, many scientists have shifted from favoring a “primordial soup” in pools of water to hydrothermal vents deep in the ocean as the original source of life on Earth. Regardless what the real beginning really was, water was certainly involved in the process some 3,5bln years ago. And since then, Mother Nature designed many ways to benefit of water and to be sheltered from it. Many engineering challenges humans face can be solved by turning to those 3,5bln years of experience and by using natural design as springboard. That’s biologically inspired engineering or, in short, bionics. BIONIC-FINISH®ECO of RUDOLF GROUP is Mother Nature’s work reproduced on textiles and apparel to protect us from water. To perform.

Back in 2003, RUDOLF GROUP borrowed from Mother Nature the idea of dendrimers (from dendron, Greek word for ‘tree’), molecules made of multi-functional branches that interact among themselves, co-crystallize, and self-organize into highly ordered, multicomponent systems. These hyper-branched polymers attach to the textile and embed fluorine-free, durable water-repellent performance.
In 2021 BIONIC-FINISH®ECO comes as a reviewed and extended family of unique nonhalogenated, APEO-free, fluorine-free formulations suited for different materials and designed for different applications and needs. Still very much based on patented dendrimer technology, the new and strengthened BIONIC-FINISH®ECO’s product portfolio:

• Provides non-fluorinated and highly durable water repellent textile finishes for high-performance, professional applications (e.g. when brushing resistance is required);
• Delivers highly efficient and durable performance with low application amounts thus not affecting fabric feel and appearance (e.g. when remarkable softness is important);
• Fulfills a range of challenging technical requirements (e.g. minimal impact on flame retardant properties of technical fibers);
• Is suitable for both sportswear and outdoor applications, as well as for casual apparel and fashion clothing;
• Is bluesign® approved, ZDHC chemical gateway certified and compliant with most RSLs;

BIONIC-FINISH®ECO new portfolio includes universal and versatile solutions targeting the most standard requirements, as well as customized solutions that meet more demanding and specific expectations such as improved resistance to dry-cleaning. “None of us can entirely predict where our voyage will lead” says Dr. Gunther Duschek, RUDOLF GROUP Managing Director. “However, BIONIC-FINISH®ECO of RUDOLF GROUP will always be the fluorine-free, durable water repellent for ultimate  performance. As it is today”.

Flexibility, product uniformity and automation are the keys to success for coating businesses in today’s rapidly-changing technical textiles industry, explained Jürgen Hanel, Monforts Head of Technical Textiles, at the recent 1st World Congress on Textile Coating.

Introducing the latest Montex®Coat magnetic roller coating option to virtual delegates from around the world at the conference organised by International Newsletters, Hanel explained why this technology makes perfect sense now

“The magnetic roller system allows a wide range of coatings and finishes to be carried out, while being easy to handle for operators and much easier to clean at the end of the process,” he said. “It provides textile finishers with an expanded range of options due to the fully-adjustable positioning of the magnet within the roller and with four different magnet positions possible, can be set to operate both as a direct coating system and as an indirect coater.”

With traditional dip coating systems, he added, as well as with many standard knife coating technologies, there is always a difference in the tension between the centre and the edges of the wide width fabrics being treated – and hence the amount of pressure with which the coating is applied. With the use of a magnetic roller, equal pressure is applied across the full width of the fabric, with consistent results even at wide widths of over 2.4 metres. In addition, adjusting the roller surface, rather than changing the coating formulation to match the required add-on and viscosity for each coating effect required, leads to much higher output from the line.

Cleaner and less wasteful
The contribution of such flexible and resource-saving new technologies to a cleaner and less wasteful textile industry was a key theme at the congress – held virtually across the four afternoons of February 11th, 12th, 18th and 19th – as was digitalization and the many advantages it is providing.

“A typical integrated Monforts coating line is automated from the inlet feed to the winder,” Hanel told delegates. “Adjustments can also be made simply and easily from the touchscreen and with the new hand-held remote controller which has recently been introduced for the Montex®Coat unit.”

Manual adjustment, he added, is time consuming and needs the attention of an experienced operator or the reproducibility will not be accurate between coating operations. The adjustment by motors allows each coating to be stored and downloaded again for 100% reproducibility.

The motors can be fully controlled from the touchscreen and all necessary adjustments carried out remotely, making switching from one process to another extremely quick and easy.
The accuracy that is now being demanded by today’s most exacting customers is met with an optional carbon fibre roller – especially in dealing with the winding tension required in the processing of materials such as prepregs for composites and other heavyweight fabrics. Typical applications for the Montex®Coat include the finishing of tents and awnings, black-out roller blinds and sail cloth, automotive interior fabrics and medical disposables. Full PVC coatings, pigment dyeing or minimal application surface and low penetration treatments can all be accommodated.

“The World Congress on Textile Coating was characterised by some very stimulating presentations and forums between the speakers and a global audience of textile specialists,” Jürgen Hanel concluded. “It truly reflected the high level of positive changes now taking place in not just textile coating, but the entire textile industry. I look forward to the next edition, which hopefully will be a face-to-face event for even deeper level discussions and debate.”

Sicomin announces its latest collaboration with GREENBOATS® as they deliver the first ever natural fibre composite (NFC) nacelle for an offshore wind turbine.  

With more than 2.5 million tons of composite materials in use in the wind industry globally, and the first generation of wind turbines now approaching end of life, there is still a lack of well-established recycling options. GREENBOATS’ mission is to demonstrate how large-scale NFC structures in wind energy can lower energy consumption in manufacturing and significantly improve the sustainability of the composite materials used in the turbine.

In 2020, GREENBOATS was commissioned by a leading wind energy technology developer to design and manufacture a sustainable NFC nacelle. The resulting 7.3m long structure has a surface area of approximately 100m2 and was engineered by GREENBOATS to satisfy all DNV-GL load cases required for an offshore turbine nacelle, including 200km/h max wind loads and 2KN loads on the guard rails.

Sicomin’s market leading GreenPoxy® range met these challenging engineering requirements, with the company’s recently expanded manufacturing capability also matching the potential supply volumes required by wind turbine manufacturers.  

Sicomin’s DNV-GL type approved bio-based epoxy was used to infuse BComp flax fibre reinforcements and balsa cores, with Sicomins’ intumescent weatherproof gelcoat applied on the outer surface. Cured panels were cut to shape, formed over a male plug and bonded together, before flax reinforcement plies, hand laminated with GreenPoxy resins and vacuum bagged, were added along all the panel joints lines.  Finally, Sicomin’s highly UV resistant clear coating products were used to protect and enhance the finish of the flax fibre feature stripe details.

A decade long collaboration between Swiss textile innovator HeiQ and Spanish premium synthetic fiber manufacturer Nylstar, has resulted in the innovation of a revolutionary new premium antiviral and antimicrobial textile with zero pollution sustainable benefits, Meryl® Skinlife Force powered by HeiQ Viroblock Permanent, winner of ISPO Textrends Award for the Best Product.

The new technology is used exclusively on Meryl® Skinlife Force, an hi-tech fabric that combines the silver-ion active principle antimicrobial properties developed by HeiQ and Nylstar’s hydrogen-based technology which allows the creation of yarns with a very strong molecular cohesion structure. The Hydrogen molecular structure makes Meryl® Skinlife Force a high-performance fabric in terms of moisture management and breathability, offering a natural stretch without elastane as well as excellent durability thanks to its continuous and high tenacity filaments. The robust durability of HeiQ Viroblock Permanent is achieved thanks to the silver particles being added directly into the raw polymer of the yarn thereby keeping these properties active for the lifetime of garments. Fabric samples successfully demonstrated a very strong antimicrobial efficacy with over 99.99% reduction of both gram-positive and gram-negative bacteria after 100 washes. Antiviral test is underway.

Both HeiQ and Nylstar will be “exhibiting” at ISPO Munich Online from February 1st to 5th. Nylstar won the Textrends 2021 Award for the Best Product in the Base Layer Category.

From the drinking water and food industries through water management and mining to the automotive and aviation sectors, mechanical filtration processes are used in almost every industry. As different as the methods, dimensions and special requirements of the filtration process are in each case – technical textiles and often tubular filters are almost always used. This means that tubular filters and narrow textiles by vombaur contribute to the safe and reliable separation or treatment of substances in the widest variety of filtration processes.

Individual solutions
The requirements placed on the textile, the material, the flow rate and the loading capacity of the filters depend on the respective use: a tubular for dewatering soil needs to withstand different forces than a tubular filter for the beverages industry. On the other hand, the latter needs to meet the highest hygiene standards. Because the requirements are so individual, vombaur develops customised filtration textiles for its customers all over the world.

Seamless tubular filters
At vombaur, filter media are round woven seamlessly on unique looms. As a result, they have identical surface properties all around and over the entire length, such as flow rate, loading capacity, shrinkage behaviour or material thickness

Narrow textiles for fabricating filter media
"We manufacture our narrow textiles from a wide variety of high-tech yarns. Sometimes monofilament yarn is used, sometimes multifilament, sometimes spun yarn. Like the type of weave, we select the raw materials depending on the function they need to fulfil," emphasises Gert Laarakker, Sales Manager at vombaur. "So that our filtration textiles reliably perform the job they are supposed to perform. Clean. Safe. Sturdy."

Hologenix, creators of Celliant®, infrared responsive technology, and Kelheim Fibres, a world-leading manufacturer of viscose specialty fibers, have partnered to launch Celliant Viscose at ISPO Munich 2021. Celliant Viscose is a finalist in Best Products by ISPO and will be showcased in the Fibers & Insulations Category for ISPO Textrends, where realistic views and 3-D simulations will be available for each material.

The introduction of nature-based Celliant Viscose will be the first in-fiber infrared sustainable solution on the market and meets a consumer demand for more environmentally friendly textiles.

Celliant Viscose features natural, ethically sourced minerals embedded into plant-based fibers to create infrared products that capture and convert body heat into infrared, increasing local circulation and improved cellular oxygenation. This results in stronger performance, faster recovery and better sleep.

Celliant Viscose provides all the benefits of being a viscose fiber — lightweight, soft, highly breathable, excellent moisture management — as well as fiber enhancements from Celliant infrared technology. Celliant’s proprietary blend of natural minerals allows textiles to capture and convert body heat into full-spectrum infrared energy, resulting in stronger performance, faster recovery and better sleep. In addition, Celliant is durable and will not wash out, lasting the useful life of the product it powers.

An Affordable, Long-lasting Solution with Diverse Applications
As opposed to other IR viscose products which are coatings based, Celliant Viscose’s in-fiber solution increases wearability and longevity with a soft feel, durability from washing and longer life. The combination of Kelheim’s distinctive technology and the Celliant additives creates this unique fiber that provides full functionality without the need for any additional processing step — a new standard in the field of sustainable IR viscose fibers. This single processing also makes Celliant Viscose more cost-effective and time-efficient than coatings.

In addition, Kelheim’s flexible technology allows targeted interventions in the viscose fiber process. By modifying the fiber’s dimensions or cross sections or by incorporating additives into the fiber matrix, Kelheim can precisely define the fiber’s properties according to the specific needs of the end product.

Highly Sustainable
Celliant Viscose is a plant and mineral-based solution for brands seeking an alternative to synthetic fibers. It contains natural raw materials that are from the earth and can return safely to the earth.

• The Bavarian Kelheim Fibres GmbH has become the first viscose fibre manufacturer worldwide to receive EMAS certification.

“Our aspiration is that our fibres offer an eco-friendly and high-performance alternative to synthetic materials”, says Craig Barker, CEO at Kelheim Fibres. “So, it’s not enough that our fibres are made from renewable resources and that they are fully biodegradable – our environmental awareness must include the whole production process and all that goes with it if we want to safeguard our credibility.

The EMAS certification proves that we take this responsibility seriously.” EMAS stands for “Eco Management and Audit Scheme” and is a standardised eco management certification system developed by the European Union. EMAS includes the globally applicable ISO 14001 standard and goes beyond its requirements by demanding more transparency and continuous improvement: Certified companies report in their annual EMAS Environmental Statement on their environmental goals and their progress in meeting them.

During the audit preceding the certification, the independent environmental auditor thoroughly investigated all departments of the company, from the production itself to the company canteen. He found no non-conformances and was impressed by the competence and the high sense of responsibility among Kelheim’s employees. In contrast to the EU Ecolabel and similar certifications, EMAS does not apply to individual products or services, but certifies the complete environmental performance of the company. This benefits not only the protection of the environment and climate, but also the improvement of a company’s ecoefficiency.

Craig Barker: “An efficient environmental management system ensures that economy and ecology go hand in hand – that gives us a decisive competitive edge.”
