Abstract

PURPOSE: A copper compound is previously mixed uniformly with poamide and then the polyamide is blended with polyester to improve the light and heat resistance without adverse effect on melt spinnability.
CONSTITUTION: A polyamide such as nylon 6 or 66 is mixed with a copper compound such as copper iodide, preferably together with a compound increasing the compatibility of polyamide such as potassium iodide. Then, the polyamide is blended with a polyester such as polyethylene terephthalate, preferably with an intrinsic viscosity of 0.5W1.0 in OCP at 25°C, so that the amount of polyamide becomes 95W70pts.wt. polyester, 5W30 parts and the copper compound, more than 5ppm, preferably 10W200ppm, calculated as copper metal. Then, the mixture is melt spun to give the objective fiber. The copper compound may be added to the polyamide at any time, e.g., the addition to the monomer, during the polymerization, or after pelletization.
