Title: Hermann Koberger: Innovator in Cellulose Technology
Introduction
Hermann Koberger is a notable inventor based in Zipf, Austria. He has made significant contributions to the field of cellulose technology, holding a total of 3 patents. His work focuses on innovative processes for creating cellulose moldings and fibers, which have important applications in various industries.
Latest Patents
Koberger's latest patents include a groundbreaking process for making cellulose moldings and fibers. This process involves preparing cellulose moldings by molding a solution of cellulose in a tertiary amine-oxide in a hot state. The molded solution is then introduced into a precipitation bath to precipitate the cellulose. A key aspect of this invention is the cooling of the hot molded solution before it enters the precipitation bath, which is achieved by blowing air horizontally onto the cellulose molding. This method allows for the spinning of cellulose solutions with high fiber density without the fibers sticking together after emerging from the spinneret. Additionally, it enables the use of a long air gap between the spinneret and the precipitation bath, allowing sufficient time to affect the textile properties of the fibers during the spinning process.
Another significant patent by Koberger is a device for the preparation of cellulose moldings. This apparatus includes a spinneret with multiple spinning holes arranged in a ring shape. An inlet for cooling gas is positioned at the center of this arrangement, immediately downstream of the spinning holes. The design incorporates a tube with a baffle plate at one end, enhancing the efficiency of the cellulose fiber preparation process.
