Abstract

L'invention concerne un procédé de production de fibres cellulosiques, consistant à extruder une solution de cellulose dans un oxyde d'amine tertiaire à travers les orifices d'une filière et à acheminer les filaments extrudés, en les étirant, dans un bain de régénération par l'intermédiaire d'une fente, où ils sont exposés à un courant gazeux. L'invention est caractérisée en ce que la température (T) du gaz, avant son contact avec les filaments, correspond à la formule : 60 ·C < T < 90 ·C.
