USAGE OF COMMERCIAL CELLULASES IN BIOPOLISHING OF VISCOSE FABRICS

Cellulases which have been in use for a long time in textile finishing were studied deeply. It is well known that cellulases can hydrolyze cotton, jute, linen, ramie and other cellulose based fiber and ensure a clean polished textile surfaces. Moreover cellulase enzyme is also used for worn and stone washed effect in denim cloths. It is possible to expand its usages. But there is a draw back in the use of cellulases for biopolishing of viscose based fabrics. Although strength loss during biopolishing of viscose fabrics was evident, the pilling and fuzz of surface did not decreased sufficiently. Because of this dilemma, a statistical research was carried out with the use of different commercial cellulase enzymes in different time and concentration. It was found that the best results were obtained from the use of CBH based Cellulase.
