Abstract

L'invention porte sur un procédé de fabrication de filaments à partir d'une solution à filer, optiquement anisotrope, lequel procédé consiste à extruder la solution à filer à travers des orifices de filage groupés dans au moins une section de filage, et à faire passer les extrudats successivement dans un gaz inerte et dans un bain de coagulation, le rapport d'espacement entre les orifices de filage et la largeur de la section de filage étant supérieur à 0,15 et inférieur à 0,7, et la largeur de la section de filage étant inférieure à 5 mm. L'invention permet de filer une pluralité de filaments présentant de bonnes propriétés physiques, à une vitesse élevée et avec une teneur acide élevée dans le coagulant sans effet de collage étendu entre les filaments.
