摘要:
There is provided polyester multifilaments for resin reinforcement which are satisfactorily homogeneously dispersed in a matrix resin to provide a filament-reinforced resin molded body excellent in mechanical characteristics and impact resistance.Polyester multifilaments for resin reinforcement to which a thermosetting resin is attached in an amount of 0.01 to 5.0% by weight based on the polyester multifilaments, and preferably the polyester multifilaments for resin reinforcement, wherein the length of multifilament bundle portions satisfying 1≦Y/X≦3 (wherein X represents the width of the multifilaments before immersion in water and Y represents the width of the multifilaments after immersion in water at 25° C. for 1 minute) is 50% or more of the length of the multifilaments before the immersion.
