ABSTRACT:
A simplified process is provided for spinning polyamide at high speed, with direct take-up on the winder of the filaments produced in which the filaments are cooled transversely under the die by means of a gaseous fluid having a moisture content of approximately 75%, brought together and oiled simultaneously at a distance of between 50 and 80 cm, preferably between 55 and 70 cm, from the die and then wound directly at a speed of at least 5,000 m/min, the maximum distance between the die and the point of contact of the filaments on the bobbin being between 130 cm and 200 cm. The yarns obtained can be used as such or may be textured according to any known means.
