Title: Innovations in Polymer Processing by Hermann-Josef Jungverdorben
Introduction
Hermann-Josef Jungverdorben, a prominent inventor based in Grevenbroich, Germany, has made significant contributions to the field of polymer processing. With a remarkable portfolio of 19 patents, Jungverdorben has focused his efforts on enhancing the efficiency and capabilities of dry spinning processes, particularly for synthetic polymers.
Latest Patents
Among his latest innovations are two notable patents that focus on improving the dry spinning process of polyacrylonitrile (PAN) fibers. The first patent details a process for dry spinning synthetic polymers, specifically PAN threads that contain over 85 wt. % acrylonitrile. This invention showcases high spinning chimney capacities of at least 20 kg of PAN solid per spinning chimney per hour, utilizing superheated steam as the spinning gas, along with in-chimney finishing with water or aqueous finishes.
The second patent elaborates on a unique method for dry spinning synthetic polymers from solutions in high polar solvents, such as dimethylformamide. This process emphasizes a pre-spinning heating stage to 100°C - 150°C and involves specific spinneret designs. It ensures that the spinning cell achieves outputs greater than 20 kg of PAN solid per cell per hour, while preventing yellowing or self-ignition of the filaments.
