Fraunhofer Institute for Spinning line for the production of high-performance fibers
Low weight with high tensile strength: technical high-performance fibers make important contributions in the field of lightweight construction and composite materials. In addition to currently predominantly petroleum-based high-performance fibers, the search for bio-based starting materials (biopolymers) for high-performance fibers is being accelerated.
In the "Fiber Technology" department, we are developing high-strength regenerated cellulosic fibers from wood-based pulp. The production of high-performance fibers usually requires high demands on the chemical resistance of the process-relevant equipment (solution preparation, filtration as well as spinning line). For a better understanding of the process in order to optimize or develop a spinning procedure for high-performance fibers, a scale is also required that allows continuous yarn spinning. We specifically examine the high-performance fibers produced with regard to their processing-structure-property relationships and develop them further.
The equipment for the production of the spinning solutions and the spinning line for their forming are funded with the help of EFRE funds within the framework of the InfraFEI program.
