From the Sector

From April 25^th to 27^th, 2023, the Institute of Textile Machinery and High Performance Material Technology (ITM) of TU Dresden will be exhibiting at the pavilion SAXONY! at JEC World 2023.

The ITM will provide a comprehensive overview of its current research in the field of machine and product development along the entire textile process chain.

The upcoming JEC 2023 exhibition will highlight innovative Customised Connective Cores (CCC), which are custom-made core-insert structures additively manufactured using cellular metal and a form-fit integrated insert. These CCCs can be seamless integrated either as patches or as full-surface core material into lightweight panels, offering significantly improved load-bearing behavior (especially 4 times the load-bearing capacity and fail-safe behavior) compared to existing technologies. This breakthrough opens up new possibilities for fastening lightweight panels.

Another highlight at the exhibition is the repair process for fibre-reinforced composites (FRP) developed at the ITM. Instead of mechanically grinding the damaged area, the matrix in the repair area is locally dissolved using a UV-rays-induced depolymerisation process. Damaged fibres can thus be replaced by a customized repair patch. Free yarn ends on the textile repair patches are spliced with the UV-exposed yarn ends in the repair area using an adapted splicing process. In this way, a very clean, simplified and mechanically improved repair area can be achieved compared to the state of the art.

The diverse possibilities offered by the structure and process simulation of textile high-performance materials and textile manufacturing processes will also be presented. By means of multi-scale modelling and simulation, a profound understanding of materials and processes is achieved at the ITM. Finite element models on the micro, meso and macro scale have been developed and validated for this purpose. Examples from current ITM research projects demonstrate the various possibilities and areas of application of modern simulation methods in the field of textile technology.

Moreover, an innovative process for the integral manufacturing of 3D rib-stiffened preforms with complexly arranged stiffeners in 0°, 90° and ± 45° orientation was developed and successfully implemented at the ITM. Due to the process-integrated structure fixation and the continuous fibre reinforcement between shell and rib structure, the 3D preforms are perfectly suited for the production of highly load-bearing FRP components with increased bending stiffness, which will be exhibited at JEC. Hence, the lightweight construction potential of high-performance fibres can be fully exploited.

A successfully established development are partially flowable 2D textile reinforcement fabrics that are continuously manufactured in one single process step. For this purpose, the entire process chain was developed at the ITM, which allows a cost-effective and high-volume production of load-bearing thermoplastic 3D FRP components with continuous fibre reinforcement between shell and stiffeners.

At JEC 2023, the ITM will also present a partially embedded textile latice girder as reinforcement for carbon concrete applications, which was produced by means of an innovative textile manufacturing process based on the multiaxial warp knitting technology. Through the development of a customized warp insertion, manipulation and take-off system as well as appropriate shaping methods, it is now possible to produce tailored textile semi-finished products, e.g. for use in wall and ceiling panels. These textile latice girders represent a resource-saving alternative to conventional steel girders due to the reduced among of concrete required and the additional cavity for media and cable guidance.

The integration of textile actuators and sensors in FRP provides structures with additional functionalities. The research and application of such interactive FRP with different matrix materials (e.g. with thermoset, elastomer or concrete matrix systems) for structural health monitoring or adaptive systems is one of the key research areas of the ITM.

Moreover, the development and implementation of innovative yarn constructions based on recycled high-performance fibres (e.g. rCF, rGF, rAR) for sustainable FRPs is successfully promoted at ITM. By use of a special carding machine, recycled fibres are opened up, separated and joined to form a wide, uniform ribbon. Subsequently, innovative hybrid yarn constructions made of evenly mixed recycled high-performance and thermoplastic fibres with variable fibre volume fractions can be manufactured by means of various spinning technologies. Selected yarn constructions and components will be showcased at JEC.

SHIMA SEIKI MFG., LTD. of Wakayama, Japan, together with its Hong Kong subsidiary SHIMA SEIKI (HONG KONG) LTD., will participate in the 40th Session of SPINEXPO in Shanghai, China from 12th - 14th April 2023.

At SPINEXPO, SHIMA SEIKI will offer visitors a choice between its "SDS®-ONE APEX4" apparel design system and its "APEXFiz®" subscription-based design software. Whereas SDS®-ONE APEX4 is offered as an all-in-one proprietary hardware + software package, APEXFiz® is subscription-based design software that can be installed on customers' individual computers. Both SDS®-ONE APEX4 and APEXFiz® software support the creative side of fashion from planning and design to colorway evaluation, realistic fabric simulation and 3D virtual sampling. Virtual samples are a digitized version of sample making that are accurate enough to be used effectively as prototypes, replacing physical sampling and consequently reducing time, cost and material that otherwise go to waste. When a design is approved for production, knitting data is automatically generated for converting to machine data, allowing smooth communication for digitally bridging the gap between studio and factory. APEXFiz® thereby helps to realize sustainability while digitally transforming the fashion supply chain.

Also on display at SPINEXPO will be SHIMA SEIKI's "yarnbank®," an online web service for searching and viewing the latest yarns, developed with cooperation from yarn companies from around the world. Registered users can download yarn data for free, for use in fabric simulation and virtual sampling on APEXFiz®, avoiding the need to scan yarn on their own. By using yarn that is used in actual production, designers and apparel companies can furthermore rest assured that the simulations created using yarn from yarnbank® are not merely realistic images but accurate representations using yarn that can actually be purchased and used in production. With yarnbank®, the entire supply chain from yarn companies and apparel companies to knit manufacturers can be connected digitally.

SHIMA SEIKI will also display the latest collection of its knit samples, including WHOLEGARMENT® knitwear that is knit in its entirety on the machine without the need for linking or sewing afterward. Together with virtual sampling performed on APEXFiz®, WHOLEGARMENT® offers smart production for realizing a sustainable fashion supply chain.

• Beaulieu International Group and Arenal announce partnership

Padel pioneers Arenal and Artificial Grass specialists B.I.G. are pleased to announce the two companies have signed a long-term partnership to drive the growth of padel in the Belgian and Dutch markets. Over the last two years, padel has been growing exponentially, and as two market leaders, B.I.G. and Arenal are looking to further develop the sport. Arenal is a leading operator of padel courts in Belgium, looking to expand under the leadership of Marc Coucke, while B.I.G. is a leading provider for artificial grass surfaces for padel, ready to market its products under its Act Sports brand.

Today 18 million people play padel worldwide, and in Spain, Portugal and Sweden, there are now more active padel players than tennis players. The same growth is manifesting itself in Belgium and the Netherlands, where the number padel courts installed in the last 2 years has almost doubled.

For the recently opened 8-court Kerkrade facility, Arenal installed Act Sports' new Score Blue padel grass court. With a brand new textured yarn developed exclusively for padel, this product offers the perfect balance in terms of ball bounce, player comfort and game consistency. It can be used both for indoor and outdoor courts, and provides a high-quality, long-life system with low maintenance requirements.

A little over three years have passed since RadiciGroup announced the acquisition of Zeta Polimeri, an Italian company headquartered in Buronzo (VC) with over 30 years' experience in the recovery of pre- and post-consumer synthetic fibres and thermoplastic materials. Today, the company has become a full member of the Group with its new name Radici EcoMaterials Srl.

The new company’s long-standing know-how, combined with RadiciGroup’s as a whole, will create a virtuous production system that recovers worn-out materials (fabric, yarn and granules), or otherwise unusable materials, and processes them into raw materials available for other production cycles by taking advantage of industrial synergy.

Radici EcoMaterials is a strategic production site because it handles all the preliminary recovery stages: the sorting, processing and pre-treatment of materials, including those used for the production of post-consumer yarns and engineering polymers. In this sense, Radici EcoMaterials is in line with the most recent European policies on sustainable textiles, which address minimizing the share of materials destined for disposal sites, favouring instead more structured recycling solutions.

Radici EcoMaterials is also GRS certified. GRS certification ensures the complete traceability of its materials, which are made in a safe plant that meets the highest environmental and social certification standards.

The company is also equipped with a photovoltaic system and, for the portion of its energy needs not covered by the photovoltaic source, it partially relies on renewable energy. The goal is to use 100% green energy in the next few years, in accord with RadiciGroup's goals.

The Institut für Textiltechnik (ITA) of RWTH Aachen University, as part of the Mittelstandzentrum 4.0 Kompetenzzentrum Textil vernetzt, has supported numerous small and medium-sized enterprises (SMEs) on their way to digitalisation over the last five years. At the Digital Capability Center (DCC) in Aachen, for example, SMEs were able to experience digitised production from yarn to smart bracelets and thus test the feasibility of Industry 4.0 solutions in their working environment.

New supply chain laws and social sustainability now pose current challenges for SMEs. In the follow-up project Mittelstand-Digital Zentrum Smarte Kreisläufe (SME Digital Centre Smart Cycles), ITA will be supporting SMEs from 1 March in implementing ideas for digitalisation and sustainability in concrete terms.

This means finding sustainable solutions and processes for the circular economy together with companies and developing new digital business models. The ITA's solutions cover the areas of awareness-raising, qualification, implementation and networking. These offers are free of charge for SMEs - follow-up projects often lead to the funding programme "Central Innovation Programme for SMEs - ZIM" of the Federal Ministry of Economics and Climate Protection (BMWK) or to research and development projects.

Questions concerning the funding conditions can be sent to the following e-mail address: rosario.othen@ita.rwth-aachen.de.

100 days before ITMA 2023 in Milan, VDMA Textile Machinery launched its “Way2ITMA” webinar series. “Transforming the World of Textiles: efficient – digital – circular”. Under this heading, VDMA technology providers will present their solutions along the value chain.

Speakers of the virtual event were Dr. Janpeter Horn, Chairman of the VDMA Textile Machinery Association and Managing Director of August Herzog Maschinenfabrik, Dirk Vantyghem, Director General, EURATEX, Francis Elias Junker, Area Sales Manager, Andritz Laroche and Tanja Karila, Chief Marketing Officer, Infinited Fiber Company.

With regard to the EU strategy for sustainable and circular textiles, Dr. Horn said: “This topic concerns all of us, consumers and producers. We as machinery builders position ourselves as enablers. We want to be part of the solution of this ambitious project”.

Dirk Vantyghem introduced the core issues of the EU textile strategy launched in 2022, which is the most ambitious plan ever, to push the textile sector towards sustainability and transparency, and promote a new circular business model. If wrongly designed, that new framework may collapse the European textile value chain. But if done rightly, the changes ahead could bring a paradigm shift in the sector, where competitiveness is no longer based on price only, but also on sustainability and innovation, explained Vantyghem.

Francis Elias Junker showed high level of expertise for mechanical textile recycling for both spinning and nonwovens industries that Andritz has. The company has a diversity of solutions to offer and several cooperation partners, covering the value chain from recovery of fiber to the chemical modification and preparation for the production of yarn.

Tanja Karila gave an overview of how Infinited Fiber is turning textile waste into new fibers. Patented technology turns post-consumer textile waste into brand new premium quality fibers for the textile industry. The textile-to-textile recycling technology captures the value in waste that would otherwise be landfilled or burned.

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

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

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

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

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

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

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

• Longer parking times for greater efficiency

Since 2018, Oerlikon Barmag has been offering the market’s only currently available concept for high-end home textile applications using the POY and DTY process. The spinning concept with the WINGS HD winding unit in conjunction with an automatic eAFK Big V Multispindle texturing machine manufactures high-titer yarns with maximum machine efficiency.
 
“We have correspondingly modified WINGS HD in order to once again better align the increased requirements of these special yarns to the spinning process and make everyday production even simpler for our customers”, comments Stephan Faulstich, POY Process Technology Manager. The parking times are extremely short when winding high titers. We have increased the parking times by up to three times in the case of the new WINGS HD models. To this end, the parking time for a 300d/384f yarn, for example, has been increased from a standard 6.5 min. to 15.7 min. – and, in the case of a 400d/192f yarn, from 4.3 min. to 10.3 min. This makes the doffing process more even, hence increasing doffing reliability.

At the same time, the draw unit now has a more flexible design, meaning that two-godet operation is also possible in the case of products with low overall titers. This has a positive impact on the winding unit’s energy consumption.

12 POY packages of up to 600d/576f (final) are produced in the spinning process using WINGS HD 1800. This is made possible as a result of an additional godet, which ensures that the high yarn tensions developing in the process are reduced to the yarn tensions common in the case of the winding process to date. At the same time, the newly-developed suction unit with the accompanying yarn cut-ting device (yarn collecting system) ensures – both during string-up and in the event of a yarn break – reliable handling of the yarn with an overall titer of 7,200 den (final).

Whereas DTY yarns up to 1,200 den and with up to 784 filaments have in the past, as standard, been plied from four POY 300d/192f bobbins using DTY machines, high titers can also be manufactured directly using the WINGS HD take-up machine. Combining the WINGS HD and the eAFK Big V allows all available winding positions to be utilized during texturing.
