Abstract

Procédé de filage << en descendant >> d'une solution de polyamide aromatique à travers une lame d'air dans un bain coagulant liquide, puis à travers un tube de filage 20 contenant les filaments fraîchement filés et du liquide coagulant, à 300 m/mn au moins. On dévie brusquement les filaments et le liquide au moyen d'un dispositif 21 situé à une distance de l'entrée du tube ne dépassant pas l'avance des filaments en 0,002 seconde, pour les amener à une distance de la paroi du tube 20 comprise entre 0,025, et 0,15 fois le diamètre de ce tube. Application à l'industrie textile.
