From the Sector

By establishing touchpoint textile, drupa has created a special forum to showcase pioneering applications in digital textile printing. The highlight will be the Digital Textile Micro Factory – a fully connected, integrated process chain starting with the customer enquiry and design through to large-format digital textile printing.

touchpoint textile represents drupa’s growing expansion into new markets comprising such segments as packaging production, large-format or industrial and functional printing next to packaging production. All of these segments are undergoing the same transformation processes and offer enormous growth potential. The special forum revolves around the opportunities and challenges of digital textile printing, brings together renowned exhibitors, industry partners and brand owners and provides scope for cross-industry cooperation, new projects as well as product and manufacturing ideas. The operational content partners of touchpoint textile include the German Institutes for Textile and Fibre Research Denkendorf (DITF), as Europe’s largest textile research centre, as well as ESMA, the European Specialist Printing Manufacturers Association.

Digital Textile Micro Factory: on-demand and virtual products – on the path towards sustainable production
In cooperation with 12 partners from industry and research the DITF will demonstrate a Digital Textile Micro Factory live at drupa and, hence, a fully connected, integrated process chain from design to finished product. This will present new possibilities for digitalisation and direct customer involvement, for instance in the form of 3D apparel simulations complete with links to design networks for creative input. Digital workflows and virtual products are integrated directly in the manufacturing process. As a special highlight for all trade visitors the technology partners of this Micro Factory will demonstrate an automated on-demand production, textile printing, cutting and sorting – without any manual interaction. Such decentralised and digitally connected design and production chains will enable the textile industry to respond to customers’ requests and trends in a more targeted manner in future. This means, touchpoint textile 2024 technologically points the way to a future without shelf-warmers. In addition, the carbon footprint for the complete process from virtual development to finished product will be modelled and presented at the trade fair.  

2024 will see the design competition “drupa – textile design talents” being held for the first time. This was conceived of by the DITF and will be implemented by the partner Mitwill. This provides up-coming textile designers and newcomers with a unique opportunity to introduce their ideas and visions to a professional audience.

Broad industry support
A project as comprehensive as the Micro Factory requires many strong partners. The companies “on board” here include: Assyst/Germany (3D simulation for digital apparel twins), Mitwill Textiles Europe/France (creative design network), D.G.I. Digital Graphics Incorporation/South Korea, Multi-Plot Europe/Germany (large-format textile printing), LEONHARD KURZ Stiftung/Germany, Zünd/Switzerland (digital cutting), robotfactory/Denmark, Asco/The Netherlands (presenting an innovative buffer solution between digital printing and cutting, automated sorting of cut parts from the cutter by robotfactory) as well as Brother/Japan (for small-format textile printing and bonding technology). Vaude and berger textiles will be sponsoring the touchpoint. Another key partner is the Albstadt-Sigmaringen University that is supporting the project as a conceptual sponsor and which has set itself the clear mission to incorporate these new topics into its curriculum. This means the staff of the future will be geared up to the new challenges ahead.

Another partner of touchpoint textile is the European Specialist Printing Manufacturers Association (ESMA), which is responsible for the lecture programme. ESMA represents industrial, functional and specialist printing and acts as an organiser of educational events in the field of textile printing. At drupa speakers from research, development, and industry will address issues related to printing and finishing techniques, workflows, market developments and sustainability, to name but a few. The focus will also be on trends and applications that unlock ever new potential through the interplay of digital printing and textile printing substrates. The lectures are divided into the categories Research, Finishing, Print Systems & Hardware, Substrates, Inks & Chemistry and Software & Electronics. Assyst, for example, will deliver talks on the virtual development of apparel as well as the research project ECOShoring, which is funded by the “Deutsche Bundesstiftung Umwelt” – DBU (German Federal Environmental Foundation) and focuses on personalised and on-demand sustainable manufacturing. Other speakers represent Adobe, Balta Group, Barbieri Electronic, Brother, Centexbel, CST, DITF, Fujifilm Speciality Ink Systems, HS Albsig, Kornit Digital, Meteor Inkjet, Mimaki, Mitwill, Multiplot, Print-Rite, RWTH Aachen, Seiko Instruments, Tiger Coatings, Xaar, Zünd and the list is updated on regular basis.

drupa will be held at the Düsseldorf Exhibition Centre from 28 May to 7 June 2024.

UK-based textile testing solutions provider James Heal has launched two new instruments in its tensile and compression testing range, marking 25 years of innovation since their first Titan universal testing machine was developed in 1999.

Having seen sustained growth in the market for personal protective equipment (PPE), particularly safety workwear, equipment and footwear, James Heal designed the Titan 25 to meet demand for quality testing products that require higher capacity tests. In addition, the company has experienced increasing demand in testing solutions for wider sporting, industrial and transportation applications, which also influenced the decision to develop higher capacity test instrumentation.

The new Titan 25 is the highest capacity universal testing machine to join the range capable of tests up to 25kN, while the 10kN Titan 10 has been newly refined. The new instruments offer efficiencies through automation, quick change connections for tooling with compatibility across the range, upgraded software, plus enhanced safety features.

These dual column instruments enable testing on larger specimens across a wide range of tensile and compression tests. Load cells from 100N to 25kN allow testing to as low as 2N giving laboratories maximum flexibility and return for their investment.

Simple to use, the new Titan testers have over 750 pre-loaded standard procedures in the TestWise software, with the option for users to customise and save their own standards. The software automatically sets parameters for each selected test, reducing set up time and eliminating user error.

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.
