CA 2206328

The invention concerns a method of producing a cellulose product by the amine oxide process, a suspension of cellulose in an aqueous tertiary-amine oxide being converted into a cellulose solution and the cellulose solution shaped and passed through an aqueous regenerating bath, thus giving a product which, following optional washing, is treated with a cross-linking agent. The method is characterized in that the cellulose solution which is shaped contains a substance which activates the cross-linking agent. The method proposed enables fibres to be produced with accurately controllable fibrillation characteristics.

L'invention concerne un procédé de fabrication d'un corps moulé en cellulose selon le procédé à l'oxyde d'amine, consistant à transformer en solution de cellulose une suspension de cellulose dans un oxyde d'amine tertiaire aqueux, à façonner la solution de cellulose puis à la faire passer à travers un bain aqueux de régénération, ce qui permet d'obtenir un corps moulé qui, le cas échéant après lavage, est traité avec un agent de réticulation. Ledit procédé est caractérisé en ce que l'on utilise, pour le façonnage, une solution de cellulose qui contient une substance pouvant servir à activer l'agent de réticulation. Ce procédé permet de fabriquer des fibres présentant des propriétés de fibrillation pouvant être contrôlées avec précision.
