From the Sector

The EU's planned ban on the entire group of per- and polyfluoroalkyl substances (PFAS) would endanger many industrial processes, states VDMA Textile Machinery. Textile manufacturing would be affected twice – by missing important chemicals for technical textile production and by the lack of indispensable textile machine components. The latter would affect the whole supply chain from textile machinery manufacturers and its suppliers to the textile industry in the EU.

Solid PFAS parts are widely used in textile machinery production, especially where extreme conditions prevail. Verena Thies, Managing Shareholder Thies GmbH & Co. KG, explains: “Our textile dyeing machines are world leaders and set standards in efficiency and sustainability. They work under pressure at temperatures of up to 140° C using highly acidic, highly basic and/or oxidative or even reductive chemicals. This is precisely why PFAS is needed, for example, in seals and rings, flaps as well as valves for a long-lasting and high-quality machine concept – because there are no alternatives with qualitatively equivalent properties. In addition, PTFE semi-finished products enable a sliding and gentle contact with the textile fabric in ecologically important techniques in the transformation of textile wet finishing."

PTFE and also FKM are fluoropolymers (fluoroplastics and fluoroelastomers), a group within the broad PFAS range of about 10,000 substances which would be banned for production, use and sale in the EU. They are high-tech materials, and as so-called "polymers of low concern" are not a danger to the environment, according to the OECD. Furthermore, these components are installed inside a machine and exchanged or disposed of properly. PFAS such as PTFE and FKM must be exempted from the ban, demands the VDMA in its position paper.

"In this way, the association also supports the approach taken in Great Britain. With the 10,000 substances, everything is lumped together, although the various PFAS groups are very different," warns Dr Sarah Brückner, Head of VDMA Environmental Affairs and Sustainability. "We should take our cue from the UK and look at the substance groups in a differentiated way."
Apart from several types of dyeing machines, PFAS components are indispensable in textile drying machines (e.g., conveyor dryers, tumblers and stenters) and damping machines. They are also used in fully automatic chemical dispensing systems and pressure vessels for thermochemical treatment of textile recycling material, heat recovery systems and wastewater treatment technology. This means that a lot of machines needed for a sustainable textile production would be affected by the PFAS ban.

VDMA Textile Machinery will take part in the ongoing EU public consultation. The association will describe indispensable key functionalities and conditions of use in the textile machinery sector as well as the consequences for the companies and the customers in the EU if the ban is imposed. The consultation ends on September 25, 2023, and VDMA urged its members affected by the planned restriction to participate in the consultation at an early stage. This is the only way to ensure that the broad scope of the mechanical and plant engineering sector is represented.

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.

• Formula 1 cars will be cheaper in future

Carbon is the stuff Formula 1 cars are made of, at least the bodywork. But until now, carbon has been expensive. It can be produced more cheaply and efficiently if artificial intelligence monitors the production processes. A camera system combined with artificial intelligence automatically detects defects in the production of carbon fibres. This makes expensive manual inspection of the carbon fibres obsolete and the production price of the carbon fibre can be reduced in the long term.

For this idea, the young engineer Deniz Sinan Yesilyurt received the second prize of the "Digitalisation in Mechanical Engineering" Young Talent Award on 6 December.

Carbon fibres are sought after because of their good properties. They are very light - they weigh up to 50 percent less than aluminium. The combination of low weight and good mechanical properties offers many advantages. Especially in times of the energy transition, lightweight materials like carbon are more relevant than ever before. At the same time, carbon fibres are as resistant to external stresses as metals. However, achieving these good properties of carbon fibres is very complex.

Up to 300 individual fibre strands - bundles of individual fibres - have to be monitored simultaneously during production. If carbon fibres tear, it costs time and money to sort out the damaged fibres. This is just one example of various defects that can occur in the fibres during production.

Therefore, Deniz Sinan Yesilyurt attached a camera to the carbon fibre line that takes pictures of various fibre defects during production and collects them in a database. The artificial intelligence in the camera's information technology system evaluates the fibre defects by assigning the images to predefined reference defects. In doing so, it recognises various fibre defects with a classification accuracy of 99 per cent. The process can also be used in other areas that produce chemical fibres.

Deniz Sinan Yesilyurt received the prize from the German Engineering Federation (VDMA) in Frankfurt am Main, Germany. He is a Bachelor's graduate at the Institut für Textiltechnik (ITA) of RWTH Aachen University. The full title of his bachelor's thesis is: "Development of a Kl-supported process monitoring using machine learning to detect fibre damage in the stabilisation process". The VDMA awarded the prize to a total of four theses from different universities. The prize is awarded for outstanding theses and was offered in Germany, Austria and Switzerland.

Dr. Harald Weber will become the new managing director of the VDMA Textile Machinery Association on 1 January 2023. The 44-year-old industrial engineer succeeds Thomas Waldmann, who has held the position since 1991 and will retire at the end of the year.

After completing his doctorate at the Technical University of Darmstadt and working as a lecturer at the University of Applied Sciences Mittelhessen (THM), Dr. Weber joined the VDMA in 2011. Since then, he has been responsible for the topics of technology and innovation in the Plastics and Rubber Machinery Association.

Dr. Janpeter Horn, Chairman of the VDMA Textile Machinery Association and Managing Director of August Herzog Maschinenfabrik, commented on the change of personnel: "From his previous work in the plastics industry, Dr. Weber has profound knowledge and experience in topics that are also gaining in importance in textile machinery manufacturing. Examples include recycling and the circular economy, as well as digitalisation and especially the communication standard OPC UA."

Dr. Horn added: "We combine our warm welcome to Dr. Weber with a big thank you to Thomas Waldmann. 30 years as managing director at the Textile Machinery Association also stand for constantly changing framework conditions. Mr. Waldmann has always had his finger on the pulse of the industry and, together with his team, has represented the special interests of the member companies: From technology policy to challenges of market access to the leading trade fair ITMA and the European association CEMATEX. ITMA 2007 in Munich was certainly a highlight. The executive board of the association wishes Mr. Waldmann all the best for the new phase of his life that is now beginning."

The 2002 prize of the Walter Reiners Foundation of the VDMA Textile Machinery Association for the best Master's thesis in German textile mechanical engineering was awarded to a young engineer from the ITA Institut für Textiltechnik of RWTH Aachen University. The prize ceremony took place at Techtextil 2022 in Frankfurt am Main, Germany. Peter D. Dornier, Chairman of the Board of the Walter Reiners Foundation, presented the award at the VDMA Textile Machinery Association’s booth.

Felix Xaver Zerbes, M.Sc., was awarded the "Promotional Prize for the Best Master's Thesis of the German Textile Machinery Industry 2022", endowed with 3,500 EUR, for his master's thesis "Development and Construction of a Separation Unit for Weft Yarns in Air Jet Weaving".

The subject of the master's thesis was the development of a mechanism with which faulty sections in the weft yarn can be sorted out before they are woven into the textile. This way, both yarn-related weft defects and material defects can be drastically reduced. The prototype developed by Mr Zerbes shows how this can be done even during the ongoing weaving process without having to stop production. Due to its modular design, the yarn rejection unit can be retrofitted to many different types of air-jet weaving machines, which represents an enormous savings potential not only in Germany but in weaving mills all over the world.

On the occasion of the Techtextil fair in Frankfurt, the Chairman of VDMA’s Walter Reiners-Stiftung Foundation, Peter D. Dornier, has awarded prizes to seven successful young engineers. For the first time, the Foundation awarded two Sustainability Awards. They are awarded to academic works in which, for example, solutions for resource-saving products and technologies are developed.

A Sustainability Prize in the category Project Work, endowed with 3.000 euros was awarded to Simon Hoebel, TU Dresden, for his thesis on recycled thermoplastic fibres for composite components.
Marina Michel, TU Dresden, received a Sustainability Award in the category Master, worth 3.500 euros. The topic of her master thesis was the functionalisation of yarns for the filtration of micro- and nanoplastics from water.

A Promotion Prize in the category Project Work, endowed with 4.000 euros, was awarded to a student group from RWTH Aachen. The teamwork of Luis Gleissner, Leopold Habersbrunner, Frederic Olbrich and Frederik Schicks was the construction of a test rig for tests on oil-adsorbing textiles.

Felix Zerbes, RWTH Aachen, was awarded a Promotion Prize of 3.500 euros in the category Master. He developed a technical solution for air jet weaving to improve the quality of woven fabric.

Monforts will highlight its advanced finishing and coating technologies for the production of technical textiles at Techtextil North America, which takes place at the Georgia World Congress Center in Atlanta from May 17-19.

The company and its US representative PSP Marketing, of Charlotte, North Carolina, will be part of the centrepiece VDMA German Pavilion at the show.

Energy prices
With energy prices continuing to go through the roof, an emphasis at Techtextil North America will be on the energy and heat recovery that can be achieved with Montex stenters, through features such as the MonforClean system, in which waste heat from the drying process is used to pre-heat the drying air. This results in a radical reduction in the conventional heat supply required. A range of further resource-saving and energy recovery options can be specified per individual line installation.

Advanced machine operation
With the highly intuitive Qualitex 800 visualization software, all article-specific settings can be stored and the formulations for thousands of treatment processes called up again at any time. Individual operators can also personalise their dashboards with the most important machine functions and process parameters.

The Qualitex 800 system is available for the automatic and continuous operation of the company’s Montex stenters, as well as its Thermex continuous dyeing ranges, Monfortex shrinking systems and Montex®Coat coating units.

Versatility is the key
Monforts Montex®Coat coating units serve an equally diverse number of markets, including tents, tarpaulins 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 and solvent coatings (in explosion-proof conditions) with knife coating, roller coating or screen printing can all be accommodated with this system.

You can read more about it in the attached document.

The Chairman of the Walter Reiners-Stiftung foundation of the VDMA Textile Machinery Association, Peter D. Dornier has awarded prizes to three successful young engineers. The award-winning works provide practical solutions on the topic of circular economy. For example, the recycling of carbon fibres, which are used to produce lightweight components for the automotive industry. Or the environmentally friendly production of yarns from crab shells. Another topic was medical applications: The processing of ultra-fine yarns into stents for aortic repair. The award ceremony took place online on 9 November as part of the Aachen-Dresden-Denkendorf International Textile Conference.  

With a creativity prize, endowed with 3,000 euros, the foundation honoured the diploma thesis of Irina Kuznik, TU Dresden. She used a creative approach to realise solutions for processing chitosan into fibre yarn.

Mr Kai-Chieh Kuo was awarded the diploma/master's thesis promotion prize of 3,500 euros. With his master's thesis, which was written at RWTH Aachen University, Mr Kuo contributes to the production of vital components used in medicine. The stents made of ultra-fine yarns are made possible by an innovative modification of the classic tube weaving process.

The Walter Reiners Foundation rewarded the doctoral thesis of Dr. Martin Hengstermann with the promotional prize in the dissertation category, endowed with 5,000 euros. The thesis deals with the production of recycled carbon fibres. These can be used to produce lightweight components for motor vehicle and aircraft construction or the wind energy sector.

New Prize Sustainability / Circular Economy
The environmental conditions of the textile industry and machine construction are changing. Topics such as climate protection and the circular economy are becoming central. From this perspective, the board of the Walter Reiners Foundation has decided to further develop the foundation's prize system.

In 2022, the foundation will for the first time offer a prize with a focus on design / sustainability. Peter D. Dornier, Chairman of the Foundation, explained: "Already in the design phase, one can set the parameters so that a textile product can be reintroduced after use into the economic cycle for a high-quality application. For example, through the appropriate use of materials and finishing. We are looking for solutions for resource-saving design, technology and manufacturing processes."   

• The Techtextil and Texprocess trade fairs have a positive view of the future and invite the sector to take part at Frankfurt Fair and Exhibition Centre from 21 to 24 June 2022.
• Exhibitors who register well in advance benefit from an early-booking discount.

The dates for the next editions of Techtextil and Texprocess have been set and the leading international trade fairs for technical textiles and nonwovens and for the processing of textile and flexible materials are set to attract exhibitors and trade visitors from all over the world to Frankfurt am Main from 21 to 24 June 2022. Thus, the fairs are shifting the biennial cycle of events from odd to even years, which fits in perfectly with the sector’s international event calendar. Companies that book exhibition space at one of the two trade fairs no later than 31 August 2021 benefit from an early booking discount. “We see the future in a positive light and are confident that we will finally be able to give the sector the opportunity to meet and exchange ideas and information in June 2022. The desire for personal encounters, direct communication and new impressions is growing from day to day”, says Olaf Schmidt, Vice President Textiles and Textile Technologies.

Elgar Straub, Managing Director, VDMA Textile Care, Fabric and Leather Technologies, emphasises that, “Texprocess and Techtextil are the world’s foremost trade fairs for our innovative sector by a large margin. Both events offer customers an unrivalled overview of state-of-the-art innovations and technological developments – and beyond. Particularly when it comes to the latest trends for sustainability and digitalisation, Texprocess and Techtextil in Frankfurt represent the most important, future-oriented market. This makes it all the more important for both the exhibitor and visitor sides of the sector that we have the opportunity to obtain an overview of the latest market developments, to exchange ideas and information and to initiate new business. We are very relieved about this and hope that, next year, we will once again have the chance to generate new momentum for our sector in the international market.”

For the first time, Techtextil and Texprocess will occupy the western sector of Frankfurt Fair and Exhibition Centre with a total of four exhibition halls and, with a hybrid format, offer the best of both the physical and immaterial worlds: personal communication, virtual networking opportunities and maximum digital coverage. With a comprehensive hygiene and safety concept, Messe Frankfurt will ensure that all visitors and exhibitors can take part safely and with a good feeling.
