Title (EN) IMPROVEMENTS IN DYEING AND FINISHING OF CELLULOSIC FABRIC
(FR) AMELIORATIONS RELATIVES A LA TEINTURE ET A L'APPRET DES ETOFFES EN CELLULOSE
Abstract: front page image
(EN)A method for dyeing and finishing a lyocell fabric or polynosic fabric includes the steps of dyeing the fabric with a reactive dyestuff under conditions such that primary fibrils are formed; removing the primary fibrils from the fabric by treatment with a solution of a cellulase; heating the solution to both denature the cellulase and induce secondary fibrillation; and drying the fabric. The method offers the advantages of low liquor usage and shortp rocessing time.
(FR)L'invention concerne un procédé permettant de teinter et d'apprêter une étoffe lyocellulaire ou polynosique, qui comprend les étapes suivantes: on teinte l'étoffe avec un colorant réactif, dans des conditions permettant de former des fibrilles primaires; on élimine les fibrilles primaires de l'étoffe par un traitement faisant appel à une solution de cellulase; on chauffe la solution à la fois pour dénaturer la cellulase et pour induire une fibrillation secondaire; et on sèche l'étoffe. Le procédé présente des avantages représentés par une faible consommation de liqueur et par une durée de traitement brève.
