60 FIBRES & TEXTILES in Eastern Europe October/December 2002 Enzymatic Treatment of Viscose Fibres Based Woven Fabric

An enzyme-based process was applied in finishing viscose fabrics, which are very susceptible to pilling because of individual loose fibres ends which protrude from surface, and impurities and fuzzes. A com-mercial enzyme of cellulase type Econase CE (Röhm Enzyme Finland Oy) and experimental cellulases such as endoglucanase II (EGII), cellobiohydrolase I (CBHI) and cellulase enriched with EGII (Cell. F) from the Trichoderma reesei strain prepared at VTT Biotechnology, Finland were used for modification of viscose-woven fabrics. This paper presents some results of studies concerning the estimation of the effect of enzymatic treatment on the changes in molecular and morphological structure of viscose-woven fabrics. Key words: viscose fabric, cellulases, enzymatic modification. Table 1.
