Title: Wilhelm Feilmair: Innovator in Cellulosic Fiber Production
Introduction
Wilhelm Feilmair is a distinguished inventor based in Seewalchen, Austria. With a notable contribution to the field of materials science, he holds four patents that reflect his innovative approach to the production of cellulosic fibers. His work has significantly impacted the textile industry, providing new methods and processes that enhance fiber quality and production efficiency.
Latest Patents
Among his latest patents, the "Process for the production of cellulosic fibres" stands out. This invention describes a novel process where cellulosic fibers are produced from cellulose solutions in aqueous tertiary amine oxide. The extruded fibers are guided through a precipitating bath, cut, and subsequently processed through a series of interconnected water baths, ensuring optimal washing conditions. A crucial aspect of this process is maintaining the pH value of each wash bath above 8.5, which enhances the quality of the fibers produced.
Another significant patent is the "Method of producing cellulose fibers," which details an innovative technique for creating lyocell-type cellulose fibers. This method uses a spinnable solution of cellulose in an aqueous tertiary amine oxide, optimized for the dry/wet-spinning process. By employing a spinnerette with over 10,000 spinning holes, this method allows for enhanced production efficiency, with precise spacing of neighboring holes to ensure uniform fiber characteristics.
