Biopolishing using cellulases was introduced in the production of cotton fabric in order to improve the quality of fabric environmental friendly and is commonly used in the textile industry. In this study, the application of a crude cellulase from Acanthophysium sp. KMF001, which was excellent for the saccharification of cellulose, on biopolishing was evaluated. The optimum treatment biopolishing condition was at $50^{\circ}C$ and pH 4.5 for 60 minutes with 10% crude cellulase of fabric weight. After the optimized biopolishing, the crude cellulase of Acanthophysium sp. KMF001 reduced the tensile strength of the tested cotton fabric less than a commercial cellulase. The appearance of the cotton fabric after the treatment of the crude cellulase of Acanthophysium sp. KMF001 was similar to the fabric after a commercial cellulase treatment. All these results support that the crude cellulase of Acanthophysium sp. KMF001 was a good biopolishing cellulase.

Five kinds of commercial ramie and hemp fabrics were treated with cellulase under different concentrations. Samples were mercerized before enzyme treatment to investigate the effect of mercerization on cellulase enzyme treatment. Physical characteristics(weight loss, tear strength retention, wrinkle recovery, drape stiffness, dyeability) of cellulase enzyme treated and untreated samples were measured and compared. X-ray diffractions were examined to verify if there were any changes in their crystallinity of enzyme treated fabrics. Weight loss, wrinkle recovery and degree of crystallinity increased as the concentration of cellulase enzyme increased. In the meanwhile, tear strength retention and drape stiffness and dyeability decreased. Enzyme activity was more effective on mercerized samples. Particularly, there was distinct tendency to increase weight loss and flexibility.
