From the Sector

Using bio-based and bio-degradable, recyclable insulation textiles to sustainably insulate heat and reduce energy consumption and the carbon footprint - the Aachen-based start-up SA-Dynamics has developed a solution for this dream of many building owners together with industrial partners. SA-Dynamics won the second Innovation Award in the "New Technologies on Sustainability & Recycling" category at the leading textile trade fairs Techtextil and Texprocess for this development.

The bio-based recyclable insulation textiles consist of 100 percent bio-based aerogel-fibres. They contain up to 90 percent air, trapped in the nano-pore system of the aerogel-fibres. The bio-based raw material is sustainably sourced and certified. The insulation textiles made from bio-based aerogel fibres are said to insulate the same or even better than synthetic insulating materials of fossil origin like PET, PE or PP and mineral or stone wool.

"By using bio-based aerogels, we are doing away with fossil-based materials and doing something for the environment and climate," explains Maximilian Mohr, Chief Technical Officer (CTO) at SA-Dynamics. "We are thus meeting the regulatory measures of the EU and the governments of many countries for more climate and environmental protection. By using bio-based, recyclable aerogels, we can revolutionise the world of construction.“

The Aachen-based start-up SA-Dynamics is made up of researchers from the Institut für Textiltechnik (ITA) and the Institute of Industrial Furnace Construction and Heat Engineering (IOB) at RWTH Aachen University.

The bio-based aerogel fibres originate from the LIGHT LINING research project of the BIOTEXFUTURE innovation area. The LIGHT LINING research project focussed on sports and outdoor textiles. The research results are transferable to the construction sector.

The Techtextil and Texprocess Innovation Awards ceremony will take place on 23 April 2024 at 12.30 pm in Hall 9.0 in Frankfurt/Main, Germany.

Under adidas’ ambition to help athletes overcome high pressure moments in sport, it has teamed up with leading sport neuroscientists, neuro11, to understand the impact it has within a game of football, basketball, and golf during penalty shootouts, high-stake putts and must-make free-throws.

Working with Emiliano Martínez, Ludvig Åberg, Nneka Ogwumike, Rose Zhang, and Stina Blackstenius, as well as amateurs in the game, adidas and neuro11 delved into their minds to identify and analyse where pressure peaks, to help athletes across the globe to better understand it.

Understanding from this study that grassroots athletes and their elite counterparts experience similarly intense levels of pressure in the biggest sporting moments - but elite athletes were up to 40% more effective at managing pressure during these moments¹ - a toolbox of techniques has been developed, built from the specific findings, to assist next-gen athletes in managing and overcoming the feeling within their game.

Covering in-depth detail on what pressure looks like within each sport, how it has been proven to impact specific in-game moments, the brain zones that neuro11’s state-of-the-art brain technology measures and the main insights from each athlete’s training session, each report sets out to support all athletes in accessing the optimal zone - the brain state in which they perform at their best.

Rounded off with science-backed tips that reveal the optimal area of a goal to strike a penalty, how to use time to regain focus before netting a free throw, as well as the impact of dwell time on putting in golf – the guides are shaped around enhancing mental focus during some of the most pressured moments across sport.

1 Findings captured during athlete training sessions, as part of adidas SS24 Brand Campaign, in collaboration with neuro11 (November ’23- January ’24). Study carried out with Emiliano Martínez, Ludvig Åberg, Nneka Ogwumike, Rose Zhang, and Stina Blackstenius, in addition to 5 grassroot athletes.

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.

Baldwin Technology Company Inc. will showcase its TexCoat™ G4 precision spray finishing system at ITMA Asia 2023 (November 19-23, National Exhibition and Convention Center, Shanghai). ITMA Asia participants can stop by and see Baldwin’s wide array of TexCoat G4-applied fabric samples from textile mills around the world and experience what precision finishing feels like while learning how the technology eliminates chemistry waste on changeover, saves water, and achieves faster speeds through the stenter frame and relaxed dryer.
 
Baldwin’s team will be available to discuss how the company’s technology can meet the textile supply chain’s sustainability and carbon footprint goals while improving performance and saving money. In the context of a cost-sensitive global economy and an increased focus by brands, consumers and regulatory agencies on sustainability, customers are placing a premium on sustainability-advantage textile production.

TexCoat G4’s non-contact spray technology offers numerous advantages compared to outdated finishing-chemistry application methods. TexCoat G4 processes a wide range of low-viscosity water-based chemicals, such as durable water-repellents –  including PFAS-free, softeners, anti-microbials, easy-care and flame retardants. The company's technology uses the same chemicals as found in traditional pad baths with no special auxiliaries required.

Testimonial videos from Pincroft Dyeing and Print Works and Graniteville Specialty Fabrics along with a video highlighting Baldwin’s partnership with North Carolina State University will also be screened at their stand.

At the crosswinds of China’s 14^th Five-Year Plan for the Development of the Marine Economy and its 14^th Five-Year Guidance for the Development of the Technical Textiles Industry lies the marine textile sub-sector. Following the government’s directive, the Marine Textile Zone will be unfurled at this year’s fair, taking place from 19 – 21 September 2023 at the Shanghai New International Expo Centre. Multiple exhibitors from across China have confirmed their participation within the zone, which will be comprised of three main parts: green marine science and nautical rope netting innovation display area, the Technology Exchange Forum, and the awards ceremony of the Top 10 Suppliers in the China Rope Net Industry.
 
The global rope market is predicted to experience a CAGR of 5.6% and grow by over USD 4 billion between 2022 - 2027[1], and suppliers are eager for the chance to meet buyers face to face. In fact, many will use the new zone at Asia’s leading technical textiles and nonwovens fair to do so.

In the green marine and rope netting category, exhibitors will showcase the latest innovations along the marine textile industry chain, anchored by application areas such as marine engineering, marine economy, marine fencing, marine rescue, deep-sea fishing, deep-sea aquaculture, and many more.

Featured exhibitors include:

• Ropenet Group: covering 36 application areas, such as aerospace, marine fisheries, safety protection, and emergency rescue, the Shandong-based company has exported to over 110 countries and regions. Products include ropes, nets, threads, and belts, with new materials and high-performance synthetic fibre spinning ropes forming the core of its business.

Meanwhile, the Technology Exchange Forum will focus on policies and regulations, strategic development opportunities, market analysis, product and process innovation, and the promotion and application of marine textiles. A range of well-known international and domestic experts have been invited to deliver comprehensive industry analysis, and unveil oceanic green textile initiatives onsite.

Designed to expand the influence of the rope net industry, the Top 10 Suppliers in the China Rope Net Industry awards will highlight enterprises currently making key contributions. Other fringe events related to this textile sub-sector include the Conference on Textile Applications for Marine Engineering and Fisheries, and the China Nonwovens & Industrial Textiles Association (CNITA) Rope Net Branch Council Meeting.

Lastly, the Marine Textile Zone will also encompass a business negotiation area to facilitate negotiations between key players onsite, set against the backdrop of the innovation display area’s award-winning and patented rope net products. As a whole, the zone is expected to encourage independent innovation in marine science and technology, coordinate the protection and development of marine resources, and help build a modern maritime industrial system.

The fair’s product categories cover 12 application areas, which comprehensively span a full range of potential uses in modern technical textiles and nonwovens. These categories also cover the entire industry, from upstream technology and raw materials providers to finished fabrics, chemicals and other solutions. This scope of product groups and application areas ensures that the fair is an effective business platform for the entire industry.

The fair is organised by Messe Frankfurt (HK) Ltd; the Sub-Council of Textile Industry, CCPIT; and the China Nonwovens & Industrial Textiles Association (CNITA).

The Danish Ministry of Defence Acquisition and Logistics Organisation (DALO) Industry Days event is scheduled to take place from 23^rd to 24^th August in Denmark. Carrington Textiles and their main manufacturing facility in the UK, Pincroft, will showcase their latest innovations in military textiles.

Carrington Textiles - after recently announcing the launch of the new stretch military ripstop fabric, Spartan HT Flex Lite, and strategically appointing the new Head of Defence and Security Fabrics -  at the event represents the commercial focus on building on an over 90 years of heritage of manufacturing military fabrics.

Likewise, Pincroft’s latest technology in non-skin contact vector protection for defence textiles and the recent involvement in printing the new Dutch Ministry of Defence’s camouflage pattern as part of their army’s uniform programme, are just a few of the textile services that will be presented at the event.

Candour Techtex, a Melegaon JR Group company, is satisfied with the latest coating and lamination line supplied by UK’s Amba Projex and has ordered a second, wider one to meet increasing demand.

Based in High Peak near Manchester, BTMA member Amba Projex has over 40 years’ experience in the design and manufacture of special purpose technical textile machines, with coating and laminating installations around the world.

Amba will be working closely with Candour over the next five years, to establish an Indian technical textiles powerhouse capitalising on the UK technology provider’s long experience in the field.

Formerly Chandni Textiles Engineering Industries, Candour Techtex of the Malegaon JR Group assumed its new name in 2022 to reflect its focus on a wide range of technical textiles at its new plant in Malegaon in the Nashik District of Maharashtra.

The company was founded in 1986 and at its existing plant in Ankleshwar, Gujarat, produces an annual 1.2 million metres of light velvet fabrics mainly for the domestic market for apparel and light home furnishings. In 2020 it also began operations at a plastic moulded components division in Gonde, Nashik, with a capacity of 4,500 tons per annum.

Blackout fabrics
In particular, the new Amba Projex system enables blackout fabrics to be produced efficiently and at scale.

Blackout fabrics are installed in rooms where complete light shielding is required, such as in public institutions like hospitals, and retirement homes, in hotels and conference rooms, and also in the home, especially in bedrooms.

They obtain their light impermeability by a special three-layer blackout coating which works on textiles of all colours. Only the middle layer of the three coatings needs to be black for obtaining the necessary light absorption. The fabrics are usually also treated for permanent flame-retardancy, and also with water or stain-repellent finishes. In addition to locking out light and providing maximum privacy, blackout curtains also help to insulate a home and reduce energy costs, in addition to protecting furniture and carpets from fading due to sunlight exposure.

The diabetic community has always been a priority for Hologenix, creators of CELLIANT® infrared technology, so the company embarked on an initial study to test the hypothesis that the technology can positively impact diabetic patients with vascular impairment, now published in Journal of Textile Science & Engineering. Another study is underway as well with more research on the horizon.

According to statistics cited in the International Diabetes Federation Diabetes Atlas, 9th edition, globally, close to a half billion people are living with diabetes and that number is expected to increase by more than 50 percent in the next 25 years.
 
The introduction of the study in the Journal of Textile Science & Engineering also reports that diabetic patients frequently suffer from a combination of peripheral neuropathy and peripheral artery disease, which particularly affects their feet. It further states that it has been estimated that the lifetime risk for the development of foot ulcers in diabetic patients can be as high as 25 percent and that the risk of amputation is 10 to 20 times higher than in non-diabetic subjects.
 
The study was performed by Lawrence A. Lavery, D.P.M., M.P.H., a Professor in the Department of Plastic Surgery at UT Southwestern Medical Center. His clinic and research interests involve diabetic foot complications, infections and wound healing, and he participated in the conception, design, implementation and authorship of the Journal of Textile Science & Engineering study.  

CELLIANT technology is a patented process for adding micron-sized thermo-responsive mineral particles to fibers, in this case polyethylene terephthalate (PET) fibers. The resulting CELLIANT yarns were woven into stockings and gloves containing either 82% CELLIANT polyester, 13% nylon and 5% spandex or for the placebo, 82% polyester with no CELLIANT, 13% nylon and 5% spandex. CELLIANT products absorb body heat and re-emit the energy back to the body as infrared energy, which is non-invasive and increases temporary blood flow and cell oxygenation levels in the body.

The objective of the study was to “evaluate changes in transcutaneous oxygen (TcPO2) and peripheral blood flow (laser Doppler, LD) in the hands and feet of diabetic patients with vascular impairment when CELLIANT gloves and stockings are worn.” While there was not a statistically significant result across all subjects, the study did show that some patients wearing CELLIANT stockings for 60 minutes had an increase of as much as 20% in tissue oxygenation and 30% in localized blood flow. According to the study’s conclusion, “the trends that were observed in favor of CELLIANT stockings suggest that a larger well-designed clinical trial should be undertaken and may provide evidence of clinical efficacy in treatment of the diabetic foot.”
 
The study also notes that “There have been no documented or observed side effects of wearing CELLIANT stockings, and they are relatively inexpensive compared to conventional pharmaceutical interventions.”

Hologenix has embarked on a more comprehensive trial, “Study to Evaluate CELLIANT Diabetic Medical Socks to Increase Tissue Oxygenation and Incidence of Complete Wound Closure in Diabetic Foot Wounds” – NCT04709419, which focuses on the impact of CELLIANT technology to potentially improve tissue oxygenation and wound healing outcomes.
 
“We are excited to explore whether future studies of infrared, with its most common biological effects of increased localized blood flow and cellular oxygenation, could result in a breakthrough in diabetic patients with vascular impairment,” said Seth Casden, Hologenix Co-founder and CEO. “We see a huge potential opportunity with this research for helping to fulfill our core mission of improving people’s health and well-being by potentially reducing the impact of diabetes, and we are actively seeking partners to expand our research efforts.”

Fibre Extrusion Technology Ltd (FET) of Leeds, UK will shortly be exhibiting at INDEX 23, the leading nonwovens exhibition in Geneva, 18-21 April.

As well as featuring its latest meltblown and spunbond technology, FET will focus on its new Fibre Development Centre. Construction and fit-out of this new purpose-built building is now fully operational. This modern two-storey development provides state-of-the-art facilities, including enhanced laboratory for client testing and product development.

Resident equipment in the Fibre Development Centre reflects the wide range of fibre extrusion systems offered by FET to clients across the globe and will enable continued growth of the company through innovation.  

Complementing FET’s highly successful meltblown technology, the more recent spunbond range provides unprecedented opportunities for the scaled development of new nonwoven fabrics based on a wide range of fibres and polymers, including bicomponents.

Under the motto “People Matter” A+A 2023, a Trade Fair for Safety, Security and Health at Work, will revolve around the most important trends of our time: sustainability and digitalisation. Here, exoskeletons also play a prominent role as tomorrow’s ergonomic tools. An important conference in this field is WearRAcon Europe which will be held at A+A from 25 – 26 October 2023 for the first time.

The Conference will be organised by the Fraunhofer Institute IPA in cooperation with the Stuttgart University and the Wearable Robotics Association (WearRA). The 38th A+A Congress, which is held by Bundesarbeitsgemeinschaft für Sicherheit und Gesundheit bei der Arbeit (German Federal Association for Occupational Safety and Health - Basi) will be closely dovetailed thematically and in terms of content with it.

Being able to walk again despite a serious injury, handle heavy parts without outside help or simply do overhead work comfortably and for extended periods of time - the advantages of exoskeletons have already convinced numerous industries. Exoskeletons and wearables are now already being used successfully in industry and commerce, and major machine builders and automakers as well as the medical sector are continuing to experiment with man-machine connections. Currently, the global market volume for exoskeletons is valued by leading analysts at over US$20 billion by 2030.¹

The WearRAcon Europe Conference 2023 will provide new insights into the promising world of exoskeleton systems from different perspectives and, in conjunction with the A+A Congress, set future-oriented impulses. Lectures by renowned exoskeleton pioneers combined with testimonials presented by users from a variety of industries and keynotes by experts will round off the programme. And, like at the previous A+A, a Self-Experience Space will again be set up so that the exoskeleton systems of various manufacturers can be tested in realistic work scenarios.

In parallel with the Self-Experience Space, the large live study Exoworkathlon will also take place again. Trainees from various mechatronic training courses have to complete a concourse and perform holding, lifting and assembling tasks, which have been specially developed with the industry. Data is prospectively collected with different measuring sensors to measure the effects of exoskeletons. In the Exoworkathlon, the IPA focuses especially on prevention for young employees in order to raise awareness of the issue and counteract ailments at an early stage.
