Latest Patents

Richard P. Dale holds a patent for a method that improves the uniformity of properties in spun polyamide filaments. The patent describes a process where flake polyamide is treated with successive nitrogen gas streams. The first stream has a variable temperature and water content, while the second stream is dry with a variable flow rate. The viscosity of the molten polyamide is determined by measuring the differential pressure across a transfer pipe. This viscosity measurement is utilized by an automatic control apparatus to regulate the flow rate of the second stream and the moisture content of a make-up stream added to the first stream. The control of these parameters ensures optimal processing conditions for the polyamide.
