Abstract
A polyamide filament is disclosed. The filament includes a polyamide resin. The resin is obtained from mixing crystalline polyamide (A) with another polyamide (B). Crystalline polyamide (A) is obtained by a polycondensation reaction of metaxylenediamine and adipic acid. Crystalline polyamide (A) comprises from 5 to 50 wt. % of the resin. Polyamide (B) comprises from 50 to 95 wt. % of the resin. The filament is heated to 160 to 200° C. under a constant length condition at an initial load of 20 mg/d. After heating, a thermal contraction stress of the filament is not reduced in a cool-down region not greater than 80° C.
