Lyocell fabric treatment to reduce fibrillation tendency

Traitement d'une etoffe en fibre lyocell (fibre de cellulose tissee dans un solvant), destine a reduire la tendance de cette fibre a la fibrillation

Abstract

The fibrillation tendency of lyocell fabrics, and the degree of fibrillation of fibrillated lyocell fabrics, can be reduced by treating such fabrics with a cross-linking agent in the presence of an acid catalyst. Good results may be obtained when the ratio by weight of the catalyst to the optional cross-linking agent is at least about 0.5:1. Good results may be obtained when the amount of cross-linking agent fixed on the fabric is in the range 0.5 to 1.5 per cent on weight of fabric.
Il est possible de diminuer la tendance à la fibrillation des étoffes en fibre lyocell ainsi que le degré de fibrillation des étoffes en fibre lyocell fibrillée, en traitant ces étoffes à l'aide d'un agent de réticulation en présence d'un catalyseur acide. On peut obtenir de bons résultats lorsque le rapport entre le poids du catalyseur et celui de l'éventuel agent de réticulation est d'au moins environ 0,5:1. On peut également obtenir de bons résultats lorsque le poids de l'agent de réticulation fixé sur l'étoffe est compris entre 0,5 et 1,5 % du poids de l'étoffe.
