On 20 July, Prof. Thomas Gries joined Sibylle Keupen, Mayor of the City of Aachen, Heiko Thomas, Councillor for Climate and Environment, Municipal Operations and Buildings of the City of Aachen, and Professor Marzia Traverso, Head of the Institute for Sustainability in Construction at RWTH Aachen University, at a panel discussion on "Textiles in the Circular Economy: Are our clothes becoming a problem?" at the Katschhof from 6 pm. (see picture, Prof. Gries is on the far right, source: ITA).

Textiles are - after food - the second most important consumer product in Germany: 20 to 25 kilogrammes are consumed per capita annually. Of this, 75 per cent is clothing, the rest is, for example, nappies, carpets or household textiles. However, the recycling rate is only one percent. How can this problem be solved? What can cities and municipalities do, what can science do? Is it possible to produce regionally produced clothing on a large scale again in Germany? Structural change also opens up opportunities for change in the textile industry.

Prof. Gries showed current projects on these topics and, among other things, how new textiles are produced at ITA from old blankets. The process addresses one of the main problems of recycling, the processing of mixed waste. With the process developed at ITA, pure acrylic fibres could be recovered from mixed waste and knitted into a cushion cover presented there.

The Citizens' Forum RWTHextern („Bürgerforum RWTH Extern“) and the City of Aachen had invited to this panel discussion. The event was moderated by Jens Tervooren from WDR.

Exchange data between textile companies openly, securely and cost-effectively without a central platform – ITA makes it possible

The Institut für Textiltechnik (ITA) of RWTH Aachen University has launched a new demonstrator for an open and secure data space in the textile industry at the Digital Innovation Centre Europe (DICE). For the first time, the demonstrator shows directly and clearly how companies can share their data securely with each other without the need for a central platform. Data exchange is based on shared, freely usable technical foundations.

Sustainable athletic wear made from bio-based Polyethylene

Conventional sports textiles made from petroleum-based synthetic fibres are to be replaced in the future by sustainable, bio-based, cooling textiles. Polyethylene, previously used mainly in the packaging industry, is thus qualified for use in textiles and, as a bio-based drop-in solution, offers a cost-effective, sustainable alternative for the future.

Small tolerances, big impact and a recyclable alternative to elastane

ITA Master's student Janne Warnecke investigated tension differences over the fabric width in the weaving process and thereby contributed to quality assurance; ITA Bachelor's student Jasmin Roos found a basis for the development of recyclable yarns and textiles. For these developments, they were awarded the Walter Reiners Foundation's Promotion and Sustainability Prizes on 27 November. Peter D. Dornier, Chairman of the Walter Reiners Foundation, presented the awards at the Aachen-Dresden-Denkendorf International Textile Conference (ADD-ITC) in Aachen, Germany.

Innovation center for textile circular economy inaugurated

Just over eight months after the foundation stone was laid, the new Innovation Center for Textile Circular Economy was officially inaugurated today at TITK Rudolstadt. Thuringia's Minister President Mario Voigt, TITK Director Benjamin Redlingshöfer, and other guests of honor cut the ribbon to the modern building complex and viewed the premises, which are now ready for occupancy. The “DICE – Demonstration and Innovation Center for Textile Circular Economy” is TITK's largest single investment to date. The Free State of Thuringia supported the total cost of €11.5 million with €8 million in GRW and FTI funding.

Sustainable design of Geosynthetics and roof underlayments made from recyclates

Is it possible to recover plastic recyclates from previously unused waste streams in order to produce high-quality fibers and films? How can bio-based polymer fibers be manufactured so as to allow adjustable biodegradability? These are the questions being addressed by researchers from the Fraunhofer Cluster of Excellence Circular Plastics Economy CCPE in the Zirk-Tex project.

More safety and comfort for protective clothing thanks to auxetic fabrics

When everyday materials are pulled, they stretch or elongate in the direction of the pull and become narrower in cross-section. We can also observe this property in two-dimensional textiles. Auxetic structures behave differently here. They have the striking property of not changing under tensile stress or even increasing their width or thickness. These properties are advantageous, for example, in protective textiles or textile filter media. The DITF are researching auxetic fabrics for various applications.

Epson launches SureColor G9000: high-production Direct-To-Film printer delivering greater productivity and reliability

Epson today announces the launch of the SureColor G9000, a new high-production Direct-To-Film (DTFilm) printer designed to meet growing global demand for flexible and efficient textile transfer printing. Expanding Epson’s DTFilm line-up alongside the SC-G6000, the SC-G9000 introduces enhanced speed, reliability and ease of maintenance for commercial garment decorators and textile producers.

Better Cotton Initiative opens enrollment in the US with promising opportunities for producers

Producer enrollment for the US Program of the Better Cotton Initiative (BCI) is open until May 15 for the 2026-2027 season. With over 2,600 members spanning the cotton supply chain and more than 11,000 users of its Better Cotton Platform (BCP) as of 2025, BCI’s standard is implemented in 15 countries and covers one fifth of global cotton production.
