From the Sector

The current European Football Championships 2024 in Germany will be played on natural turf, which is very costly to maintain, does not tolerate high frequency of use and has a limited service life of only 6 months in some cases. Artificial turf is easier to maintain and correspondingly popular. In Germany, there are estimated to be more than 5,000 artificial turf pitches and as many as 25,500 across the EU. The drawback: the enormous annual emission of microplastics in the form of infill material, the high CO2 impact and the not environmentally friendly disposal. Researchers in Aachen presented a sustainable alternative: BioTurf is a new artificial turf system made from bio-based polymers that no longer requires polymer infill material!

"Every year, around 500 kilograms of plastic granules are produced per artificial turf pitch, which have to be refilled as infill. This also corresponds to the amount that potentially enters the environment as microplastics per sports pitch," explains Dr Claudia Post from TFI. With an estimated 25,000 artificial turf pitches in the EU, artificial turf in Europe alone produces 12,750 tonnes of microplastics that end up in the environment every year! The TFI - Institut für Bodensysteme an der RWTH Aachen e.V., Institute for Research, Testing and Certification in Europe for Indoor Building Products, has developed the innovative artificial turf system together with the ITA (Institute for Textile Technology at RWTH Aachen University) and in collaboration with the company Morton Extrusionstechnik (MET), a specialist in artificial turf fibres.

"New artificial turf pitches will be phased out by 2031 at the latest due to the ban on plastic granules. Even now, artificial turf pitches with infill material are no longer being subsidised," says Dr Claudia Post. For grassroots sports, clubs, cities and local authorities, converting their existing artificial turf pitches will be a mammoth task in the coming years, as artificial turf pitches have to be replaced every 10-15 years. With BioTurf, an environmentally friendly alternative is now available! The surface can be played on like any other, whether running, passing or kicking. Short, heavily crimped blades support longer blades and this simple approach increases playing comfort. BioTurf fulfils all quality requirements and standards for the highest footballing demands.

"BioTurf is an innovative, holistic solution," emphasises Dirk Hanuschik from TFI. "We use rapeseed oil and agricultural waste that does not compete with food production. BioTurf is also almost completely recyclable".
This is in stark contrast to conventional artificial turf, which can currently only be thermally utilised, i.e. burned to generate heat.

As BioTurf does not require the traditional latex process at all, the energy-intensive drying process can be dispensed with, which has a positive effect on the price. Latex is also difficult to recycle. In contrast, BioTurf uses the new thermobonding technology. Here, the thermoplastic pile yarns are thermally fused to the backing. Further development steps still need to be taken in the endeavour to develop a 100% mono-material artificial turf, as a few percent polypropylene still needs to be processed in the backing in addition to the polyethylene fibre material in order to protect it during thermobonding. However, this does not hinder its recyclability.

At the upcoming SaigonTex, taking place from April 10th to 13th in Ho Chi Minh City, the KARL MAYER GROUP will present its innovations.

DThe KARL MAYER exhibition for warp preparation is entirely dedicated to sustainability. With BLUEDYE, an innovative machine is introduced, which ensures more sustainability and lower costs in the process of indigo dyeing. Thanks to innovative technological solutions, the amounts of water and chemicals used are significantly reduced. Additionally, less yarn waste is generated. Another innovation for more sustainability is CASCADE, a steam and condensation system that requires significantly less steam in the drying process of sizing and indigo dyeing plants by using a solution for energy recycling that is protected against imitation.

For the warp knitting sector, the group of companies presents its latest technological developments. Highlights include a digital solution from KM.ON for optimizing production management (DPM), innovations for enhancing performance in the HKS segment, and a double raschel machine that enables unique creative multi-color designs in spacer textiles with more colour and new Jacquard techniques.

"Vietnam is a growing market for textile production, which is gaining importance especially for major international sports brands," says Eddy Ho, Senior Sales Manager at KARL MAYER.
The sales professional expects a large number of visitors, especially from Vietnam, China, Taiwan, and South Korea. SaigonTex is one of the most important textile machinery exhibitions in East Asia, located in close proximity to production centres. Vietnam is, in turn, the second most important market for the KARL MAYER GROUP after China. It benefits from increasing foreign direct investments in textile production from China, Taiwan, and South Korea.

Freudenberg Performance Materials (Freudenberg) is showcasing solutions for the automotive, building, apparel, filtration and packaging industries at this year’s Techtextil in Frankfurt am Main from April 23 – 26.

Sustainable nonwoven for car seats
One innovation highlight at Techtextil is a novel Polyester nonwoven material for car seat padding. Also available as a nonwoven composite with PU foam, it is not only easier for car seat manufacturers to handle during the mounting process, but also ensures better dimensional stability as well as providing soft and flexible padding. It has a minimum 25 percent recycled content, for example, by reusing nonwoven clippings and waste, and is fully recyclable. Full supply chain transparency enables customers to trace and verify the content of the nonwoven and thus ensures a responsible production process. The Freudenberg experts will also be presenting several other nonwoven solutions made of up to 80 percent recycled materials that can be used in car seat manufacturing.

Biocarrier for green roofs
Freudenberg is showcasing a sustainable carrier material for green roofs on urban buildings at the trade fair. The carrier is made from polylactide, i.e. from renewable resources. When filled with soil, it provides a strong foothold to root systems, enabling the growth of lightweight sedum blankets that can be rolled out to provide instant green roofs. These roofs not only help counter urban heat, they also improve stormwater management and regulate indoor temperatures.

From textile waste to padding
The company extended its circular thermal wadding product range with the release of comfortemp® HO 80xR circular, a wadding made from 70 percent recycled polyamide from discarded fishing nets, carpet flooring and industrial plastic. Because polyamide 6, also known as nylon, retains its performance characteristics after multiple recycling processes, the fibers can be used again and again to manufacture performance sporting apparel, leisurewear and luxury garments.

Packaging solutions with various sustainability benefits
Freudenberg is also showcasing products for sustainable packaging and filtration solutions. The long-lasting Evolon® technical packaging series is a substitute for disposable packaging used in the transport of sensitive industrial items such as automotive parts. The material is made from up to 85 percent recycled PET. A further highlight at Techtextil are Freudenberg’s fully bio-based solutions for manufacturing dessicant bags. The binder-free material based on bio-fibers is also industrially compostable.
In addition, the experts will be giving trade fair visitors an insight into Freudenberg’s filtration portfolio.

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® 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.

Making outdoor sports accessible to as many people as possible since 1976 through quality, innovative gear, powerhouse sporting goods brand Decathlon has launched the first product of its long-term partnership with CELLIANT® infrared technology from Hologenix® – Adult Ski Socks. They are introduced in its Wedze range of ski and snowboarding socks (“wed’ze” means ‘“a small turn on the snow” in the Savoyard dialect in the Alps where this brand is headquartered).  

Decathlon was attracted to CELLIANT’s ability to convert body heat into infrared energy, improving local circulation and cellular oxygenation to support stronger performance and faster recovery. Skiers who often suffer from muscle fatigue in the calf area will appreciate the infrared infusion and light compression attributes that were specifically chosen with this in mind. The sock was also thoughtfully designed for minimum thickness, allowing for a comfortable fit within the ski boot, without sacrificing warmth or durability. Anti-friction thread on the sole and toes helps limit irritation, and seams are intentionally positioned to eliminate discomfort. The socks are offered in a Asphalt Blue color in a variety of sizes, both online and in retail stores worldwide.

Devan, part of Pulcra Chemicals, has announced its R-Vital NTL technology.

R-Vital NTL enables textile manufacturers to boost textiles with a versatile range of micro-encapsulated active ingredients. This functional finish provides added value for textiles and allows manufacturers to create products that differentiate them from competitors. Furthermore, the bio-based and biodegradable well-being technology achieves a durability of 50 washes.

The main concept behind micro-encapsulation is that active ingredients, present on textiles, are gradually released on the skin. When using the textiles or while wearing the clothing, the microcapsules burst by friction and release their assets. Since not all capsules break at the same time, a continuous and gradual release of the actives is obtained.

The natural range comprises five distinct products, each with specific attributes:

• Aloe vera: Known for its skin-smoothing and softening properties.
• Avocado seed oil: Known for its skin-moisturizing capabilities.
• CBD: Known for its relaxation properties.
• Multivitamin: A blend of provitamin D, vitamins C and E, and ginger.
• Vitamin E: Known to offer protection against free radicals and premature aging

• Award for near-net-shape 3D meshes for use in fibre-reinforced plastics

As part of the JEC FORUM DACH 2022, the AVK Innovation Awards were presented in Augsburg on November 29th. The innovation price in the category "Research/Science" (first place) was awarded to the team of scientists Dipl.-Ing. Dominik Nuss, Dr.-Ing. Cornelia Sennewald and Prof. Dr.-Ing. habil. Chokri Cherif.

With the development of the pull-off-free Jacquard weaving technology including the technological know-how in the field of highly complex 2D and 3D fabric geometries, which has been established at the ITM of the TU Dresden for many years, Dominik Nuss has succeeded in including different yarn lengths locally into the fabric structure solely through targeted variation of the fabric weave. There-fore, it is now possible to produce completely new types of fabrics without additional draping, especially spherically curved fabrics, but also large-format spiral or even curved fabrics. The fact that the required near-net-shape geometry of the component to be reinforced can be reproduced with significantly reduced preforming steps is to be emphasized.

Continuous simulation aided engineering from CAD design to integrally woven 2D and 3D preforms by means of highly complex weave development for spatial constructions is a unique at the ITM, which was indispensable for the development of these promising woven high-tech structures. This technology is completely new and has never been carried out in this way before. The fabric structures are characterised by a high innovation level due to their geometric diversity and purposes. It can be used in numerous applications and further more contributes to the development of completely new fields of application. The technology can be implemented on all Jacquard weaving machines with only an additional device and the preform geometry is only determined by the control of the Jacquard machine. The preform geometry can be used in the full working width of the weaving machine.

Professor Chokri Cherif, Institute Director of the ITM, and his team are very pleased about these continuous research success in the constantly growing research field of 3D weaving technology, which are achieved at the ITM in close cooperation with industry and users. "This award is a special honour for our institute and confirms that the many years of our excellent research in the field of near-net-shape 3D weaving for the fibre-reinforced plastics sector plays a significant role and that we are making a significant contribution to the sustainable and resource-efficient production of lightweight structures with our development".

The identification of profitable new niche markets has been central to the success and continuous expansion of Germany’s Dolinschek, a leading knitting, dyeing and finishing specialist, located in Burladingen in Baden-Württemberg.

“There is so much more to textiles than just clothing,” says Theo Dolinschek, who runs the company with his brother Erwin. “We handle many different technical materials such as automotive components, geotextiles and wallcoverings, but also those for more unusual applications such as inlays for extractor hoods, cut protection fabrics and even wool felts which are employed as insulation on wind turbines.

“We have also recently started to produce compression stockings in a variety of colours, because not everyone wants them black, beige or skin coloured. The most important product areas for us now are in sportswear, corsetry and lingerie, as well as orthopedic and medical products, workwear and protective clothing, but in addition, many other technical applications.”

The Dolinschek brothers moved their business to the historic site of the former Ambrosius Heim textile company in Burladingen in 2001 in order to expand. At the time, the company – founded by their father in 1980 as a textile wholesaler before moving into dyeing – employed just 13 people. Within a year, the company had bought additional space at the site.

Now, with Theo in charge of technology and sales, and Erwin responsible for production, the company employs almost 100 people and operates on an integrated site of 35,000 square metres.

In 2005, a laminating department was established by the company and since 2012 investment in knitting machines has been ongoing.

“The further we went into vertical integration, the more of our own products we were able to position on the market and so we were also able to make ourselves more independent,” says Theo. “We have continued to develop and today we can produce high-quality fabrics for many fields, with 42 knitting machines, 36 dyeing machines, three stenter frames and many other production and processing machines.”

Dolinschek has also developed its own proprietary TMG dyeing machines which have subsequently been successfully sold to many other companies all over the world. There are currently 11 of these machines  in operation at the Burladingen site and around 45 installed at other companies.

For finishing technology, however, the company relies on Monforts, and has installed a new seven chamber Montex TwinAir stenter range with a Montex®Coat coating unit in knife execution, enabling the coating of dimensionally stable knitted fabrics with polyurethane or acrylate. Another unique feature is the Teflon-coated (non-stick) transportation belt through the system.

The Montex line is also equipped with integrated heat recovery and exhaust gas purification to ensure the most resource-efficient processing available on the market. The exhaust air goes from the Monforts heat recovery system into an existing air/water heat recovery system and then into an electrostatic precipitator.

Highly-intuitive Monforts Qualitex visualisation software allows all machine functions and process parameters to be assessed and controlled easily.
