POLYAMIDE POLYMER FIBER, METHOD FOR PRODUCING POLYAMIDE POLYMER FIBER, POLYAMIDE POLYMER COMPOSITION, WOVEN FABRIC AND KNITTED FABRIC

摘要

Provided is a highly durable polyamide resin fiber, a method for manufacturing such polyamide resin fiber, a polyamide resin composition, a woven fabric and a knitted fabric. The A polyamide resin fiber comprising 0.5 to 15 parts by weight of a compound represented by Formula (1), per 100 parts by weight of a polyamide resin,the polyamide resin being composed of a diamine-derived structural unit and a dicarboxylic acid-derived structural unit, 50 mol% or more of the diamine-derived structural unit being derived from xylylenediamine, and 50 mol% or more of the dicarboxylic acid-derived structural unit being derived from a straight chain aliphatic ±,É-dicarboxylic acid having 4 to 20 carbon atoms: in Formula (1), R 1 represents an alkyl group having 1 to 10 carbon atoms, R 2 represents an alkyl group having 2 to 12 carbon atoms, and n represents an integer of 1 to 3.
