Title
(EN) A METHOD FOR DESIZING CELLULOSE-CONTAINING FABRIC
(FR) PROCEDE DE DESENCOLLAGE DE TISSU CONTENANT DE LA CELLULOSE
Abstract
(EN)
Cellulose-containing fabrics or textile may be desized without essentially damaging the fabric or textile by subjecting the fabric or textile to a treatment with a certain type of cellulolytic enzyme, e.g. a cellulolytic enzyme having an activity on carboxymethylcellulose (CMC) and a catalytic activity on cellotriose at pH 8.5 corresponding to kcat of at least 0.01 s-1 and preferably being of microbial origin, more preferably being obtainable by or derived from a strain of $i(Humicola, Trichoderma, Myceliophthora, Penicillium, Irpex, Aspergillus, Scytalidium) or $i(Fusarium).
(FR)
On peut désencoller des tissus ou des textiles contenant de la cellulose sans les détériorer, en soumettant le tissu ou le textile à un traitement avec un certain type d'enzymes cellulolytiques, par exemple une enzyme cellulolytique présentant une activité sur la carboxyméthylcellulose (CMC) ainsi qu'une activité catalytique sur la cellotriose à un pH de 8,5 correspondant à kcat d'au moins 0,01 S-1, et de préférence d'origine microbienne, l'enzyme étant idéalement obtenue ou dévirée d'une souche de $i(Humicola, Trichoderma, Myceliophthora, Penicillium, Irpex, Aspergillus, Scytalidium) ou $i(Fusarium).
