Dr. Ludewig, inventor of the continuous polymerization process (VK-tube) came to Schwarza. This first VK-tube with a one-step process was used commercially.
Development of various VK-tubes with which made it possible to reach an increase of the capacity to up to 10 tons per day; Development of POY and FDY spinning processes.
First implementation of a 2-step (P10/E10) technology in the production; present a continuous extraction and drying processes.
Development of a multiple-step-technology: Producing of PA-6 with a viscosity of LV 3.3(after extraction and drying) for the utilization in the tire industry as tire cord. High speed spinning with 4200 m/min.
