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.

Walter Reiners Foundation Prize awarded to three ITA graduates

Sabina Dann, Lukas Balon and Annegret Storm from the Institut für Textiltechnik (ITA) of RWTH Aachen University were awarded the Walter Reiners Foundation Prize by the German Engineering Federation (VDMA) for their master’s and bachelor’s theses. Peter Dornier, Chairman of the Walter Reiners Foundation, presented the awards during Techtextil at the VDMA stand in Frankfurt am Main, Germany.

Young talents honoured – 60 years Walter Reiners Foundation

At the Techtextil trade fair in Frankfurt at the end of April, Peter D. Dornier, chairman of the VDMA’s Walter Reiners Foundation, presented awards to five successful young engineers. Promotion and sustainability awards were presented in the categories of bachelor’s/project theses and diploma/master’s theses. Academic theses are eligible for the sustainability awards if, for example, they develop solutions for resource-efficient products and technologies.

Regional hemp bast for lightweight construction profiles

The cultivation of fibre hemp for the production of ropes and clothing has a long tradition in Saxony. Due to its excellent fibre properties, it is also suitable as a renewable raw material for reinforcement in fibre composites. At the STFI and IWU in Chemnitz, the CannaPul project is cur- rently investigating how a regional value chain for hemp-based lightweight construction profiles can be established. To this end, the technical processing of hemp fibres into continuous fibre strands and their embedding in a suitable bio-based matrix are being investigated.

BB Engineering unveils new, patented “Val-uePack” spin pack at ITM

At the upcoming ITM in Istanbul, taking place June 9–13 at the Tüyap Fair Convention and Congress Center in Hall 7, Booth 702B, BB Engineering will once again be represented at a joint booth with its parent company, Barmag, and its representative, Tekstil Servis. The German machine manufacturer will show-case its expertise in man-made fiber and recycling technology, presenting its entire product portfolio, which includes compo-nents such as extruders and filters, as well as complete sys-tems for spinning synthetic fibers, air-texturing, and PET recy-cling.

ITM 2026: KARL MAYER presents new perspectives

KARL MAYER will once again showcase itself as a strong partner to the Turkish textile industry at ITM in Istanbul from June 9 to 13. At Booth 303 A in Hall 3 of the Tüyap Fair Convention and Congress Center, the industry leader will exhibit solutions for warp knitting, warp preparation, and technical textiles – tailored to a challenging economic environment.

STFI highlights textile circular economy and alternative fibres at INDEX™ 2026

From 19 to 22 May 2026, INDEX will invite visitors to Lake Geneva for the world's leading nonwovens trade fair. The Centre of Excellence in Nonwovens at the Sächsisches Textilforschung- sinstitut e.V. (STFI) will be in attendance to present the latest developments in nonwovens research. In the field of the textile circular economy, the STFI will present acoustically effective nonwovens made from chemical recycling residues. The range also includes innovations aimed at replacing conventional raw materials, such as the biobased and biodegradable polymer polybutylene succinate (PBS) and Kendyr as an alternative to cotton.
