Title: Walter Roggenstein: Innovator in Polyamide Yarn Technology
Introduction
Walter Roggenstein is a noteworthy inventor based in Sainte Foy les Lyon, France. He holds two patents that significantly contribute to the field of polyamide yarn production. His innovative techniques have improved the efficiency of yarn spinning, making a profound impact on the textile industry.
Latest Patents
Among Roggenstein's notable patents is the "Process for obtaining polyamide yarns with better output efficiency." This invention addresses the challenges faced during the spinning of polyamide-based preoriented yarns at high speeds, specifically speeds of at least 4000 m/min. By introducing 0.05 to 1% by weight of pyrogenic silica, with particle sizes between 5 and 15 nm, into the molten polymer prior to spinning, Roggenstein's process enhances output efficiency by at least 10%, often exceeding 15%. The resulting preoriented yarns exhibit a delay in orientation and are sized and wound at speeds between 4200 and 5800 m/min after being cooled by a gas stream at room temperature.
