Abstract

PURPOSE: The title filter medium usable for spinning polyamide incorporated with a soluble copper and an organic sulfur compounds, capable of preventing the oxidation of the medium surface effectively with simple treatment, manufactured by nitriding a stainless steel medium.
CONSTITUTION: A stainless steel wire mesh is pretreated with a salt bath of NaCN- NaCl-Na2CO3, and nitrided in a box with ammonia gas at 400W600°C for 10W 100hr. The mesh is scarcely clogged even when a polyamide incorporated with a soluble copper compound, e.g. about 50W500ppm calculated as Cu of a copper halide or copper salt of an organic acid, and an organic sulfur compound, e.g. about 0.05W0.50% of mercaptobenzimidazole, is melt spun. Thus, good spinnability and stretchability can be obtained for a long time.
