COMPOSITE FIBER FABRIC KNITTED ARTICLE AND COMPOSITE MATERIAL

摘要

Provision of composite fibers in which polyamide resin fibers and continuous reinforced fibers are dispersed. A composite fiber comprising a polyamide resin fiber (A) made of a polyamide resin composition, a continuous reinforcing fiber (B), and a treatment agent (a) of a polyamide resin fiber (A), wherein the amount of the treatment agent (a) is , Polyamide resin fiber (A) is 0.1 to 2.0% by mass, the polyamide resin composition is a polyamide resin derived from xylylenediamine, at least 50 mol% of the diamine constituent units, the number average molecular weight (Mn) It is 6,000-30,000, and the composite fiber whose 0.5-5 mass% is polyamide resin whose molecular weight is 1,000 or less.
