ITA PhD student Kai-Chieh Kuo was awarded Best Master’s Thesis Award of Walter Reiners-Stiftung (Foundation)

Kai-Chieh Kuo, PhD student at the Institut für Textiltechnik (ITA) of RWTH Aachen University, was awarded the German Textile Mechanical Engineering 2021 Best Master's Thesis Award for his master's thesis entitled "Modification of the tube weaving process of fine yarns for the production of woven ultra-low profile stent grafts". The prize is endowed with 3,500€. Peter D. Dornier, Chairman of the Board of the Walter Reiners-Stiftung (Foundation), virtually presented the award on the occasion of the ADD International Textile Conference on 9 November 2021.

Significant advance in aortic prostheses through high-density, thin-walled tubular woven fabric

Minimally invasive endovascular aortic repair (EVAR) with textile stent-graft systems is nowadays a clinically established therapy procedure for the treatment of abdominal aortic aneurysms (AAA) – pathological bulges of the aorta. Due to the thick profile of the folded stent graft systems, there is currently a high risk of injuring narrowed or highly angulated access vessels from the inside during implantation. Stent graft systems with smaller profiles could provide an improvement, which could overcome complicated access routes through a lower bending stiffness. One possible approach for reducing the system profiles is the use of thin-walled tubular woven fabrics made of ultrafine multifilament yarns (?20 dtex) as graft material.

Up to now, it has not been possible to process the fine yarns with the required high thread density (>200 threads/cm) and the available weaving technology in order to guarantee sufficient tightness against blood.

In his master's thesis, Kai-Chieh Kuo made high-density tubular weaving of ultra-fine filament yarns possible for the first time by means of suitable modifications to a shuttle loom as well as adaptations in the weaving preparation. In particular, he developed a new innovative reed technology that reduces warp thread friction during the shedding process and thus improves the process stability of the dense tube weaving process of fine yarns.

With the help of the process modification, it was then possible to produce high-density, thin-walled tubular woven fabrics, which were positively evaluated with regard to their suitability for a stent graft. Above all the potential of these tubular fabrics lies in their extremely thin-walled fabric profile, which seals well against blood. By using these new types of tubular fabrics as graft material for stent grafts, the system profile of the folded stent graft system can be reduced without having to compromise the blood tightness of the implant. The technology developed by Mr Kuo is not only applicable to stent graft systems, but also offers great possibilities for use in all other endovascular implants such as trans catheter heart valves, covered stents and small-lumen vascular prostheses.

Through its Walter Reiners-Stiftung (Foundation), the VDMA Textile Machinery Association is actively involved in promoting young engineers. Every year, the Foundation awards prizes for the best dissertation, diploma or master's thesis and the creativity prize for the cleverest student research project. In 2020 and 2018, ITA graduates have already been awarded promotional prizes from each category.

Networking Day 2026: Industry stakeholders unite around textile recycling

In 2026, the Industry Research Group (IRG) Polymer Recycling once again brought together some of the key stakeholders in textile recycling for its annual Networking Day. This year, the event took place at EREMA’s premises in Ansfelden, Austria. It brought together key players from across the textile recycling value chain for a day of structured exchange and in-depth discussions.

2026 general meeting of the Friends and Supporters of RWTH Aachen at ITA

The Friends and Supporters of RWTH Aachen e. V. (proRWTH) looked back on a successful year of support at their 2026 general meeting. The meeting took place at Institut für Textiltechnik (ITA) of RWTH Aachen and was combined with a joint session of the Executive Board and the Administrative Board. Before the general meeting began, participants were given a guided tour of ITA, providing them with fascinating insights into current research and development topics in textile engineering.

TERNAfil wins first place at PitchMiUp Night 2026 in Minden

The RWTH spin-off TERNAfil has developed MAXCarbon, a new high-performance hybrid fibre that combines the mechanical performance of carbon with the temperature and corrosion resistance of ceramic materials. For this development, TERNAfil was awarded first prize at the PitchMiUp Night in Minden on 21 May 2026.

Carbon-ceramic hybrid fibre proves its worth – NRW Minister for Science Mona Neubaur congratulates ITA start-up TERNAfil

MAXCarbon technology, a novel carbon-ceramic hybrid fibre developed by ITA spin-off TERNAfil, secured third place at the HIGH-TECH.NRW Demo Day on the TÜV NORD campus in Essen. The technology combines the strength of carbon fibres with the temperature and corrosion resistance of ceramic materials. Mona Neubaur, Minister for Science in North Rhine-Westphalia, congratulated the team on their success and on winning prize money of 4,000 euros.

Outdoor Industry Association completes Clean Heat CoLab initiative

The Outdoor Industry Association (OIA) has completed its multi-year Clean Heat CoLab initiative, bringing together outdoor brands and technology experts to accelerate the adoption of electrified process heating in textile manufacturing. The collaboration focused on reducing emissions from thermal processes such as dyeing, washing and finishing, which remain among the most carbon-intensive stages of textile production.

Europe is committed to recycling end-of-life wind turbine blades

Starting in 2026, Europe’s wind energy industry has committed itself to ensuring that wind turbine blades do not end up in landfills once they reach the end of their service life. The EU-funded research project REWIND is exploring ways to reuse this composite waste. The German Institutes of Textile and Fiber Research Denkendorf (DITF) are one of 13 project partners from seven countries.

ADD-ITC 2026 publishes preliminary conference program

The organizers of the Aachen-Dresden-Denkendorf International Textile Conference (ADD-ITC) 2026 have released the preliminary program for this year's event, which will take place on November 26–27, 2026, at the International Congress Center Dresden. The conference is expected to attract between 500 and 700 participants from industry, research, and academia.
