Abstract

Agent coagulant aqueux pour solutions cristal-liquide à base de matières cellulosiques, caractérisé en ce qu'il comporte au moins un additif soluble dans l'eau choisi dans le groupe constitué par l'ammoniac, les amines ou les sels de ces composés, l'additif étant tel que le pH dudit agent coagulant est supérieur à 6. Un additif préférentiel est un sel choisi dans le groupe constitué par les formiates, les acétates et les phosphates d'ammonium, les sels mixtes de ces composés, ou les mélanges de ce constituants, notamment l'orthophosphate diammonique (NH4)2HPO4. Procédé de filage d'une solution cristal-liquide à base de matières cellulosiques, mis en oeuvre avec un agent coagulant conforme à l'invention, notamment procédé dit de "dry-jet-wet-spinning"; articles filés, fibres ou films, obtenus selon ces procédés. Fibre cellulosique ayant une ténacité supérieure à 40 cN/tex, un module initial en extension supérieur à 1200 cN/tex et un résistance à la fatigue élevée; sa déchéance en force-rupture .DELTA.F après 350 cycles de fatigue au test dit "test de barreau", sous un taux de compression de 3,5 % et une contrainte de tension de 0,25 cN/tex, est inférieure à 30 %.
