Abstract

Uzun süreden beri tekstil terbiyesinde kullanılan selülazlar üzerine yoğun araştırmalar mevcuttur. Selülazların pamuk, jüt, keten rami ve diğer selüloz esaslı lifleri hidrolize ettiği ve temiz parlak tekstil yüzeylerinin elde edilmesini sağladıkları iyi bilinmektedir. Selülaz enzimi ayrıca denim giysilerde taşlanmış ve giyinmiş efekti için de kullanılmaktadırlar. Selulazların kullanım alanlarını arttırmak mümkündür. Fakat selülazların, viskon kumaşların bio-parlatmasında kullanılmasında sorunlar mevcuttur. Bio-parlatma sonrası viskon kumaşlarda mukavemet kaybı gözlemlenirken kumaş yüzeyindeki pilling ve tüylülük yeterli miktarda azalmamaktadır. Bu ikilem nedeniyle farklı ticari enzimlerle farklı süre ve konsantrasyonlarda istatistiksel bir araştırma yapılmıştır. En iyi sonucun Sellobiohidrolaz (CBH) esaslı selülaz enzimi ile elde edildiği tespit edilmiştir

USAGE OF COMMERCIAL CELLULASES IN BIOPOLISHING OF VISCOSE FABRICS

Abstract

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
