Abstract

L'invention concerne les fils de polyamide préorientés. Les filaments filés sont renvidés à une vitesse qui n'est pas inférieure à 3 000 mètres/minute, et on fait passer lesdits filaments à travers une zone de conditionnement après qu'ils aient été refroidis et avant d'être renvidés. Application notamment aux fils de nylon 6 (polycapronamide texturés.
