From the Sector

Smart textiles have the potential to revolutionise healthcare. In his doctoral thesis in textile technology at the University of Borås, Emanuel Gunnarsson presents unique solutions to the bottleneck that has long inhibited the market.

With an ageing population, increasing demands are being placed on healthcare and smart textiles can offer a solution where only imagination sets limits. “The long-term goal of most smart textiles is for them to be so easy to use that the user doesn't think of them as anything more than regular garments. No special procedure should be needed to use them. If we succeed in that, we won't burden healthcare by having healthcare personnel administer vital parameter monitoring such as blood pressure and pulse, as the user can handle it themselves,” said Emanuel Gunnarsson.

In his work, he has investigated how a t-shirt for measuring heart rhythm and movement patterns, and garments for electrostimulation, can be produced in a single step. This involves the connection between the contact surfaces (electrodes), the insulated conductive paths between the electrode and the contact point, and the electrical measuring equipment required.

“This, as far as we know, has never been described before. We are completely convinced that this is the solution to a significant bottleneck when it comes to getting the smart textile market going in earnest,” said Emanuel Gunnarsson.

His work has resulted in two different simple ways to produce smart textiles. He demonstrates that sensors can be integrated using standard textile manufacturing methods. The research also includes criticism of some of the methods used to measure the functionality of smart textiles, and advice on how to do it better instead.

“The next natural step will be to see how these garments cope with one of the toughest challenges a garment faces, namely washing. Especially as these garments must be worn closest to the skin, they will need to be washed relatively often,” said Emanuel Gunnarsson.

Studies from other universities indicate that the yarns used to measure signals from the body do not withstand many washes, but after a small pilot study, Emanuel Gunnarsson is hopeful of the opposite.

• ITA Master's graduate wins Hanns Voith Foundation Award 2023

In his Master's thesis, Flávio André Marter Diniz, a graduate of the Institut für Textiltechnik of RWTH Aachen University (ITA), developed ultra-thin polyethylene (PE) carbon fibres with a filament diameter 2-3 times smaller than usual. In addition, the use of PE-based precursors will make it possible to reduce the price of carbon fibres by 50 per cent in the future, thus opening up a wide range of other possible applications in key industries such as wind power, aerospace and automotive. For this groundbreaking development, Marter Diniz was awarded the Hanns Voith Prize with the Hanns Voith Foundation Award in the category "New Materials". The prize is endowed with € 5,000 in prize money.

Flávio André Marter Diniz won the prize in the category "New Materials" for his master thesis entitled "Investigation of the stabilisation and carbonisation process for the production of ultra-thin polyethylene-based carbon fibres".

The use of carbon fibres in highly stressed lightweight construction solutions, such as today's growth applications of wind turbines or pressure tanks, has become indispensable due to their excellent mechanical properties and low density. High manufacturing costs of conventional PAN precursor-based carbon fibres make the material very cost-intensive. In addition, it is not sufficiently available. New manufacturing approaches that develop alternative raw materials and manufacturing processes can be a key and growth engine for further industrial composites applications.

The aim of the work was to develop a new and cost-effective manufacturing process for high-quality ultra-thin carbon fibres using a polyethylene precursor. For this purpose, the sulphonisation process, which is time-consuming today, was to be significantly shortened. As a result, Mr. Marter Diniz produced novel ultra-thin polyethylenebased carbon fibres with a filament diameter < 3 μm with an excellent surface quality of the fibres without detectable structural defects. The fibre diameter is 2-3 times smaller than that of conventional PANbased CF. This provides the basis for mechanically high-quality material properties. At the same time, Mr. Marter Diniz was able to reduce the sulphonisation time by 25 percent. The developed material and technology set important milestones on the way to cheaper carbon fibres. With PE-based precursors, the price of CF can be reduced by 50 percent compared to conventional PAN-based CF.  

A total of five other young scientists were awarded in six categories (Drive Technology, Innovation & Technology/Artificial Intelligence, New Materials, Paper, Hydropower and Economic Sciences. This year, for the 10th time, the Hanns Voith Foundation awarded the Hanns Voith Prize to outstanding young scientists.

• 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".

• Unveil UK’s first-ever sustainable Fashtech Innovation Centre, displaying mass customization capabilities empowering designers, apparel brands, and other creatives

Kornit Digital Ltd. (NASDAQ: KRNT), a worldwide market leader in sustainable, on-demand digital fashionx and textile production technologies and Fashion-Enter - a social enteprise, which strives to be a centre of excellence for sampling, grading, production, and for learning and development of skills within the fashion and textiles industry – today announced a first-of-its-kind Fashtech Innovation Centre in London. Aimed at bringing on-demand fashion and textile mass customization back to the UK, and unveiled on March 3rd and 4th, 2022 at Fashion-Enter's state-of-the-art training and manufacturing site, the Centre is fully supported by Kornit Digital's revolutionary, direct-to-fabric and direct-to-garment digital production solutions.

According to Kornit Digital’s Impact and Environmental, Social and Governance (ESG) report, 30 percent of textile production is overproduction, while 95 percent of water waste is created as companies globally look towards more sustainable futures with customized, creative, and real-time offerings. Using proprietary streamlined, eco-friendly digital production technologies, Kornit Digital is transforming the fashion industry with more efficient and sustainable processes. According to the same report, by 2026, the Company’s systems will use up to 95 percent less water, 94 percent less energy and produce 83 percent less greenhouse gas emissions.

In addition to highlighting production capabilities that minimize carbon footprint, the Fashtech Innovation Centre serves as a prototype for brands and fulfillers seeking to mitigate logistical complexities, time-to-market, and supply chain risks by bringing production nearer to the end consumer. Eliminating overproduction and producing on demand, this nearshoring model drives profitability even in highly regulated and high-cost markets while contributing to local economies and removing transport-related waste.

Serving as a fulfilment site and academy for training production, the Centre includes both Kornit Presto direct-to-fabric and Kornit Atlas MAX direct-to-garment systems, as well as numerous graphic design and workflow tools and systems to enable cut-and-sew operations for a comprehensive “pixel to parcel to doorstep” cycle. Consolidating the process into a single location helps maintain full visibility and control of operations and products. Taking this one step further for creators and brands, visitors can experience the KornitX Global Fulfilment Network, enabling customers to create both new sales channels and accessibility to enable production on demand. Attendees can see how Kornit’s single-step digital production technology empowers unlimited graphic expression using less floor space, resources, waste, and time—all at higher margins.

“This Innovation Centre makes it possible to capture the full, end-to-end production process in one, single location,” said Jenny Holloway, Chief Executive Officer, Fashion-Enter. “The beauty of having print on demand means there are no minimums, so we can make one garment, or we can make up to 30,000 garments a week from all locations at the same fixed cost. Here, we can also train future generations on the right way of producing garments for today, responsive to demand, with minimal waste—ethical and sustainable. This is the future of fashion and textiles.”

Monforts textile technologist Jonas Beisel will outline the benefits of the company’s Econtrol® continuous dyeing process during the next free-to-attend VDMA Textile Machinery Webtalk which takes place on February 3rd 2022 at 13.00 (CET).

“Our customers are increasingly looking at shorter production runs and the more economical use of dyestuffs, as well as reducing water and energy consumption,” says Beisel. “We have gained many years of experience in the optimisation of dyeing processes through working with our customers, both at their own plants and in our Advanced Technology Centre (ATC) in Mönchengladbach, Germany.

“Our Thermex universal hotflue for continuous dyeing, curing and thermosoling achieves unrivalled reliability even at high fabric speeds, for exceptional cost-effectiveness when dyeing both large and small batches of woven fabrics. The Econtrol® process for reactive dyestuffs now has an impressive number of references on the market, as a quick and economical one-pass pad-dry and wash off process. This is the ideal process for fast change technology and operational savings.”

Among key benefits are the saving of resources compared to conventional continuous dyeing methods, excellent reproducibility of pale to dark shades, from lab to bulk, and greater flexibility in production planning due to a resulting dry fabric that does not need an immediate wash off.

Econtrol® is a registered trademark of DyStar® Colours Distribution GmbH, Germany, and Bertram Seuthe of DyStar® will be providing recommendations for dyes and auxiliaries for the process during the VDMA event.

A third speaker, Guido Seiler of Fong’s Europe, will explain how Goller washing ranges help to significantly reduce the water that is conventionally wasted in the washing off process, through a combination of process and chemistry know-how and advanced technologies.
