Latest Patents
Herbert A. Spiller holds a patent for a method of treating polyester filaments. This method focuses on producing polyester staple yarn that exhibits low elongation and shrinkage while maintaining high tenacity and modulus. The process involves drawing a tow of conventionally spun polyester filaments in an aqueous draw zone, followed by drying at temperatures between 130°C and 140°C. The filaments are then stretched by 1.1 to 1.2 times and heat set at temperatures ranging from 170°C to 200°C. The careful control of dwell time between the drying and stretching steps is crucial to prevent crystallization, ensuring optimal stretchability. The method culminates in crimping, cutting to staple, and spinning into yarn.
