| Abstract: | The relationships between ccllulasc activities and the properties of treated fabrics including weight loss, breaking strength, surface thickness and bending rigidity were investigated. Three ccllulascs were used to treat two kinds of cotton fabrics and the results were compared to their activities measured towards filtcr paper, CMC and dcwaxed cotton. The results suggested that among the three activities, cxo activity (measured towards dcwaxed cotton) be mostly Inclined to reflect the actual hydrolytic capability of the ccllulasc on cotton fabrics, while endo activity (measured towards CMC) was of little use in predicting cellulase efficiency in terms of weight loss. The investigation also suggested that the relatively endo - rich cellulase (Ccllusoft Plus) was inclined to give biopolishing effects by cleaning the surface fibril of fabrics while the exo - rich cellulase (Ccllusoft L, also known as total or full ccllulasc) tended to deliver softening effects by decreasing the bending and shearing properties. |
