FIELD: chemistry.
SUBSTANCE: invention relates to a composite fibre, in which a polyamide polymer fibre and a continuous reinforcing fibre are dispersed. Composite fibre includes (A) a polyamide polymer fibre made of a polyamide polymer composition, (B) a continuous reinforcing fibre and (a) an agent for treating polyamide polymer fibre (A), wherein the amount of the treating agent (a) ranges from 0.1 to 2.0%, based on the weight of polyamide polymer fibre (A); and the polyamide polymer composition comprises a polyamide polymer comprising diamine structural units, 50 mol% or more of which is derived from xylylenediamine, and having a number average molecular weight (Mn) of 6000 to 30000; and 0.5 to 5 wt% of the polyamide polymer has a molecular weight of 1000 or less.
EFFECT: obtaining a fibre.
