IPF at DESY: Investigations of structure formation in polymers

Challenging but successful days for scientists (Eric Euchler, Anna Sambale, Regine Boldt, Enno Henn, Sitao Wang, Lutz Zybell, Kai Uhlig) from the Institute of Polymer Materials (headed by Prof. Markus Stommel) of the IPF at DESY P03 beamline.

For the first time, the FlowCell device developed at the IPF was used in combination with a conventional single-screw extruder at the MiNaXS beamline P03 to investigate the crystallization kinetics during the solidification of processed iPP, PA6 and PLA melts. The experiments could only be performed remotely, consequently, the FlowCell and extruder control had to be fully integrated into the instrumentation of the beamline.

The conducted experiments are part of the IPF-DESY Long-Term Project (LTP, no. II-20220003) to develop an experimental setup for in situ investigations of (micro)structure formation in polymers (transcrystalline structures, flow-induced crystallization, phase separation) under defined process conditions that are typical and relevant for common melt processing technologies such as extrusion or injection molding.

The IPF scientists would like to thank Matthias Schwartzkopf and Sarathlal Koyiloth Vayalil for the excellent support at the beamline and the team of IPF Research Technology (Forschungstechnik) for the technical implementation of the research ideas.

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.

Fraunhofer CCPE presents the “Monomaterial Design Set” – Innovative solutions for circular product design

Composite materials made from different types of plastic often extend the lifetime of products but make recycling more difficult in the circular economy. That is why Fraunhofer CCPE has developed the “Monomaterial Design Set”. This new approach helps to reduce the variety of plastics used in durable products and offers circular solutions for designers and product developers.

How innovations drive BASF’s success

“Innovation has always been part of BASF’s DNA. Especially in these volatile times, it is crucial to leverage our innovative strength to develop competitive solutions that differentiate us as a company in our markets and give us a competitive edge,” said Dr. Stephan Kothrade, Member of the Board of Executive Directors of BASF and Chief Technology Officer, at the company’s Research Press Briefing held today. To achieve this, BASF implemented its “Winning Ways” strategy about a year ago with the clear goal of becoming the preferred chemical company to enable its customers’ green transformation.

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.

Happy Holidays!

Dear reader, the year 2025 is drawing to a close. We are entering what we hope will be a peaceful holiday season, spending time with our families and taking a moment to pause and reflect. We hope we have been able to support you once again this year with relevant news and articles, and we look forward to surprising you with many innovations in the coming year. Enjoy the festive season, stay healthy, and we wish you a happy and joyful holiday season.

Texpertise Focus AI: Messe Frankfurt puts Artificial Intelligence centre stage at its international textile and apparel trade fairs

Under the banner 'Texpertise Focus AI, Messe Frankfurt will place a strong emphasis on Artificial Intelligence (AI) across its international textile and apparel trade fairs from 2026 onwards, setting a future-shaping signal for the industry. The initiative highlights the responsible use of AI along the entire textile value chain, from fibre production to the point of sale. The programme will launch at Heimtextil in Frankfurt in January 2026.

Autoneum and Polestar set new benchmarks for passenger experience and sustainability

As the global market leader in sustainable acoustic and thermal management, Autoneum is a key supplier of interior and exterior components for the highly anticipated Polestar 5 model. The successful collaboration between Autoneum and Polestar marks a significant milestone in sustainable automotive engineering: the electric grand tourer sports car features several innovations in lightweight, fully recyclable polyester-based components that ensure a superior driving experience. Polestar 5 was revealed at the IAA Mobility 2025 in Munich and is available in 24 markets.
