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.

In recognition of his extraordinary engineering achievements in the fields of textile mechanical engineering, textile technology as well as textile chemistry and surface modification of textile semi-finished products, Prof. Paul Kiekens was awarded the title of Doctor honoris causa (Dr.-Ing. h.c.) on April 5, 2023.
 
Prof. Kiekens was a university professor at Ghent University, Belgium, for almost 35 years and thus responsible for textile-oriented education and research. Intensive interaction with European business and science was always particularly important to him.
 
Immediately after the fall of the Berlin Wall, he opened the way for international cooperation in teaching and research in the field of textile mechanical engineering, textile technologies, and textile chemistry for the only Eastern European university research institution with a textile orientation, the ITM (formerly ITB) at the Faculty of Mechanical Engineering of TU Dresden, and provided great and uncomplicated support. A close, lasting and intensive relationship developed, which had a trend-setting influence on the scientific career of Professor Paul Kiekens. This was reflected above all in the expert advice given for major projects.
 
These include, for example, the funded junior research group "Holistic approach to the development and modelling of a new generation of multiaxial fabrics for fibre composites to strengthen Saxon, French and Flemish industry in the high-performance sector" (SAXOMAX) and jointly acquiring the EU project "Large scale manufacturing technology for high performance lightweight 3D multifunctional composites" (3D-LightTrans). Especially in these large-scale projects, intensive cooperation with industrial partners was essential for success.
 
As early as the 1990s, Professor Paul Kiekens had the vision of creating a European network for universities in textile teaching and research. In 1994, the Association of Universities for Textiles (AUTEX) was founded with the aim of establishing teaching and research in the field of textile technology at an internationally respected level through joint concepts. Due to the prevailing cooperation at that time between Professor Dr. Paul Kiekens and Professor Dr. Peter Offermann, the TU Dresden, represented by the ITM (formerly ITB), has been a full member and decisively integrated in the network since its foundation on July 1, 1994. Thus Prof. Dr.-Ing. habil. Paul Kiekens has significantly promoted the international cooperation of the TU Dresden, Faculty of Mechanical Engineering with international university textile research institutions.
 
Professor Paul Kiekens was executive coordinator of AUTEX until his retirement. The internationally renowned symposium takes place annually as a part of AUTEX.

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.”

At ITMA 2023 in Milan, Zünd is focusing on the advantages of digital single-ply cutting in modern garment production.

At the show, Zünd will demonstrate the advantages of individual cutting on demand and what benefits single-ply cutting of textiles offers. In the course of digitalization, the market environment of the apparel industry has changed. Producers are responding to increasing digitalization and ever-shorter product life cycles by investing in lean and highly automated production workflows. Solutions from Zünd supported process streamlining from ordering to cutting while minimizing manual interventions.

Zünd's single-ply cutters are the cutting tools in digitized production, offering manufacturers flexibility and profitability. Intelligent automation functions, optical solutions and software tools facilitate resource optimization, keep an eye on material consumption and support employees who can turn their attention to value-adding activities. With digital single-layer cutting, manufacturers speed up their cutting and expand their production capacities at the same time. They can accept orders at very short notice and easily meet delivery times thanks to highly economical and efficiently scalable on-demand production. Peaks in demand can be easily managed.

Zünd cutters give users new flexibility in their production workflow. He can work with complex motifs, demanding textiles and different shapes. The cutting technology enables the apparel industry to produce highly individualized customized garments in small batches and on demand just as economically and efficiently as in high volumes. It can process and handle more orders in less time. At the same time, both material and time are saved. In combination with the MindCut production software and precise single-layer cutting, there is almost no waste. The cut parts can be nested very close to each other and close to the material edges. This not only offers considerable savings potential, but also helps to reduce the ecological footprint.

SABIC will present its portfolio of PURECARES™ and TRUCIRCLE™ materials for the healthcare and hygiene market at INDEX™23 from April 18 to 21 in Geneva, Switzerland, under the theme of ‘Collaborating for sustainability and innovative solutions’.

At INDEX, SABIC will highlight a joint project with two market leaders, using certified circular polymers from the TRUCIRCLE portfolio in recyclable films for feminine hygiene, baby care and disposable medical applications. In all of these cases from diapers to surgical drapes and medical gowns, the sustainable materials can serve as direct drop-in alternatives with no compromise in production efficiency and product performance.

Further examples on display at the company’s booth will feature TRUCIRCLE solutions for facemasks, including an N95 design that localizes the value chain with SABIC® PURECARES PP spunbond and meltblown polymers in Saudi Arabia. SABIC provides complete solutions for facemask production as part of its localization strategy and has been a key enabler of the Saudi Made initiative. Also shown will be a closed-loop facemask developed in collaboration with industrial and research partners in Europe.

The company’s PURECARES polyolefin products are based on technologies free of both tris (nonylphenyl) phosphite (TNPP) and phthalates. Consumer comfort is achieved by using SABIC polypropylene (PP) and polyethylene (PE) polymers for bi-component fibers to answer multiple needs for soft and loft handfeel nonwovens, enabling easy lamination to other building blocks on medical nonwovens or absorbent hygiene applications.

In addition, SABIC produces TRUCIRCLE certified circular polymers for its PURECARES PP and PE portfolio with feedstock based on advanced recycling of mixed and used plastic that would otherwise typically not be suitable for mechanical recycling processes. These more sustainable solutions can be adopted in downstream processes as direct drop-in alternatives to incumbent materials with no compromise in production efficiency, purity and product performance.

With a current booking level of almost 90% for the international fabric trade show MUNICH FABRIC START, KEYHOUSE, THE SOURCE and BLUEZONE, Munich Fabric Start Exhibitions GmbH is starting the new season for Autumn.Winter 24/25 on a strong footing. From the organisers' point of view, the main reason for the high level of acceptance is the rebalancing of the July dates.

The international fabric trade show MUNICH FABRIC START (18 to 20 July), the innovation hub KEYHOUSE, theb one-stop sourcing platform THE SOURCE and the international denim trade show BLUEZONE (18 and 19 July) will move ahead and at the same time increase their relevance in the international trade show scene. For a large part of the visitors, the earlier date is closer to the collection rhythms and offers more time for further developments.

What's new?
Due to the early date of MUNICH FABRIC START and BLUEZONE, the Munich trade show duo with KEYHOUSE and THE SOURCE formats will function even more strongly as an impulse generator and leading international event. The Munich location will also be strengthened by the relocation of the DMI Fashion Day from Düsseldorf to the Bavarian capital. The first DMI FASHION DAY LIVE will take place the day before the next MUNICH FABRIC START at the MOC.

The course will also be set anew in September: The date, which remains important for the industry, will in future be occupied by reVIEW - the new format of the VIEW PREMIUM SELECTION for follow-ups and trends as well as new market developments. On an area of around 2,500 square metres, the first reVIEW Autumn.Winter 24/25 will be held on 13 and 14 September 2023 on the Zenith grounds in Motorworld.

On 30 March 2022, the European Commission presented its vision for the future of the textile industry. The strategy mainly focuses on reducing the environmental footprint and promote sustainability and transparency in the value chain.

EURATEX has welcomed the publication of the strategy, as it recognises the strategic importance of the European textile industry, and its core competitive values of quality and creativity. At the same time, the association has warned that translating that vision into reality is a delicate process, as the industry needs to reconcile sustainability with competitiveness. Making the green (and digital) transition should make companies stronger; the benefits should outweigh the costs.

This premise had a serious blow by the Russian war in Ukraine, which erupted at almost the same time when the strategy was launched, and has dramatically changed the economic context. Energy prices increased by a factor of 10 (!), putting the European industry at a significant disadvantage with its global competitors, leading to company shutdowns or relocations. Extended lock downs in China and defensive trade policies in the US and elsewhere have further generated uncertainty on the market and disrupted supply chains.

Today, one year after its publication, EURATEX remains carefully optimistic about the implementation of the strategy, but needs to warn against some important pitfalls on the road ahead.

1. Despite these turbulent times, the Commission is moving ahead “swiftly” in translating their EU Textile Strategy into (draft) legislation. At present, at least 16 pieces of legislation are on the table, which will turn the textile industry into a strictly regulated sector. The quality of this new regulatory framework is critical to the success of the strategy: upcoming rules need to be coherent, technically feasible and enforceable, and have a minimal cost for SMEs. EURATEX calls for a realistic timetable and “competitiveness test” for each piece of legislation before it is adopted.
2. Textile companies need to be informed and supported to comply with this new framework. This requires substantial funding which should be earmarked exclusively to the sector, covering areas of innovation and digitalisation, skills development, support to start ups and internationalisation, as well as access to affordable energy. In this regard, EURATEX calls on the Commission to translate the current “good intentions” into concrete decisions.
3. The EU strategy will not work if there is no demand for sustainable textiles, both from individual consumers and public authorities (procurement). Concrete measures need to be taken to offer a competitive advantage to sustainable and high quality textile products, e.g. through a different VAT rate, strict procurement rules, closer cooperation between the brands/retailers, producers and consumers.
4. The EU strategy could also fail, if the global dimension of the textile industry is ignored. Up to 80% of clothing products are produced outside the EU; these products need to comply with the new framework, but it remains unclear how to ensure that level playing field. Market surveillance needs to be stepped up massively – also targeting on line sales – but this would require significant efforts from member states, which are not available as of today.

Despite these important challenges, EURATEX remains committed to the successful implementation of the EU Textile Strategy. Director General Dirk Vantyghem commented: “We want to be a global leader in sustainable textiles, building on the entrepreneurship, quality and creativity of nearly 150,000 European textile companies. Creating this new framework is an incredible challenge, requiring a close dialogue between the industry and the regulator. But if well designed and carefully implemented, it can set a new era for the European textile industry”.

National Council of Textile Organizations (NCTO) Chairman David Poston delivered the trade association’s State of the U.S. textile industry overview at NCTO’s 19th Annual Meeting on March 30.

Mr. Poston’s speech highlighted the impacts of macroeconomic factors on the U.S. textile industry and the resilience of the U.S. textile industry; trade and investment data showing growth in the sector across the board; and NCTO’s policy priorities for domestic textile manufacturers.

“The U.S. textile and apparel industry faced challenging macroeconomic conditions throughout the year,” Poston states in the speech. “Despite these challenges, there were also many positive trends that helped offset some of those pressures, including softening inflation towards the latter half of the year, coupled with a surge in onshoring and nearshoring that led to historic investments, commitments and expansion in the U.S. and the Western Hemisphere.”

• Electromagnetically heatable nanomodified stent for the treatment of hollow organ tumours wins second place at the RWTH Innovation Award

Almost every fourth person who dies of cancer has a hollow organ tumour, for example in the bile duct or in the oesophagus. Such a tumour cannot usually be removed surgically. It is only possible to open the hollow organ for a short time using a stent, i.e. a tubeshaped prosthesis. However, the tumour grows back and penetrates the hollow organ through the stent. Ioana Slabu from the Institute of Applied Medical Technology and Benedict Bauer from the Institut für Textiltechnik of RWTH Aachen University have now developed a novel technology for the therapy of hollow organ tumours, which was awarded second place in the RWTH Innovation Award. This involves a polymerstent that contains magnetic nanoparticles. When electromagnetic fields are applied, these nanoparticles lead to a controlled heating of the stent material and thus of the tumour. Because the tumour reacts much more sensitively to heat than healthy tissue, it is destroyed and the hollow organ remains open. Thus, the stent develops a self-cleaning effect.  

Ioana Slabu of the AME explains: "Not only can we drastically reduce treatment costs, but above all we can provide relief for millions of patients worldwide.
 
A manufacturing process and proof of concept for magnetic hyperthermia are already in place. This novel technology has a very high development potential because it can also be used for tumours in other parts of the body such as the prostate, stomach, intestine or urinary bladder or for cardiovascular diseases.  

The AiF/IGF project started under the project title "ProNano" funded by BMWK. Now the approval for the follow-up project "ProNano2" has also been received. The approved project is called: "Validation of the innovation potential of heatable stents for heat-induced treatment of cavity tumours" and is funded by BMBF in course of the VIP+ program. With the Clinic for General, Visceral and Transplantation Surgery of the University Hospital Aachen and the Institute for Technology and Innovation Management at RWTH Aachen University, the consortium is enriched by clinical and economic expertise. Every year, RWTH Aachen University honours particularly innovative university projects with the Innovation Award. Professor Malte Brettel, Prorector for Business and Industry, presented the certificates to four outstanding projects as part of RWTHtransparent.
