The technology, the reverse osmosis water recovery system and the innovative spinning head design for “large traction” production, helps reduce production costs and improve fiber quality. Overall, Dr. Peterek’s work describes the opportunities and challenges of the polyacrylonitrile market and is innovative for sustainable, safe and cost-effective fiber and carbon fiber production that meets current political and social demands. Emphasizes creative solutions. Institut für Textiltechnik of RWTH Aachen University (ITA) stated in a media release that the choice of alternative solvents, the corresponding process design, the impact on fiber properties and manufacturing costs play a central role in this work.
In his treatise, Dr. Peterek investigated the market for polyacrylonitrile fibers, focusing on the current political and economic framework of Europe. An important element in this context is the “REACH” reform. REACH (Registration, Assessment, Authorization, Restriction of Chemicals) is a regulation of the European Union that addresses the production and use of chemicals and their potential impact on both human health and the environment.
Dr Stefan Peterek, an ITA scientist, wrote Paul in his paper “Cost-Effective Wet Spinning of Polyacrylonitrile Fibers with Alternative Solvents” at the awards ceremony at the Digital Opening Event of the Dornbirn GFC Global Fiber Convention in Austria. Received the Schlack Prize 2021. He worked with industry partners to develop technical solutions.
The EU is currently regulating substances that impair carcinogenicity, mutagenicity, and fertility in order to improve occupational safety. The regulation even includes setting new limits and even banning these substances. It also affects the solvents most commonly used in the production of polyacrylonitrile fibers. Therefore, manufacturers are forced to switch to alternative solvents. Solvent changes are associated with significant investment in new plants and significant conversion costs. Therefore, the motivation for Dr. Peterek’s research was to investigate the use of less toxic solvents and identify challenges and opportunities for process changes.
To maintain social and political acceptance (work safety, sustainability) and economic competitiveness with other textile materials, the choice of auxiliary materials and solvents, and process design set specific boundary conditions. Must be met.
Since 1971, the Paul Schlac Award has been awarded at the Dornbirn GFC Global Fiber Congress (formerly Dornbirn Artificial Fiber Congress) in Dornbirn (Austria) to promote artificial fiber research at universities and research institutes. Previous ITA winners of the Paul Schlack Prize were Dr. Andreas De Palmenaer, Dr. Gunnar Seide, Dr. Wilhelm Steinmann, Dr. Stephan Walter, Dr. Gisa Wortberg, Dr. Benjamin Weise, and Dr. Markus Beckers (Paul Schlack-Honorary Award).
