A polyoxymethylene fiber which comprises a polyoxymethylene copolymer which exhibits a half crystallization time of 30 sec or more when it is cooled from the molten state at 200~C to 150~C at a cooling rate of 80~C/min and then is held at 150~C constantly. The polyoxymethylene fiber has a high strength and a high modulus of elasticity.

L'invention concerne une fibre en polyoxyméthylène renfermant un copolymère de polyoxyméthylène qui présente un temps de demi-cristallisation d'au moins 30 secondes, lorsqu'il est refroidi de l'état fondu de 200 ·C à 150 ·C à une vitesse de refroidissement de 80 ·C/min et, puis, il est maintenu constamment à 150 ·C. Ladite fibre en polyoxyméthylène possède une résistance élevée et un module élevé d'élasticité.
