Abstract

Broad, mercerized broad, mercerized twill cotton fabrics and rayon fabric were treated with cellulase for 30~480 minutes at different temperature, concentration, time, and also treating methods such as continuously-treated or repeatedly-treated, and dyed with two direct dyes before or after enzyme treatment. From the experimental result by treating under the various conditions above, it was obtained that the weight loss increased more in thin fabric than thick one. In addition, it was considered that the treatment in 5$0^{\circ}C$ for 240 minutes brought about the ideal weight loss and flexible hand of the specimens. For both broad and mercerized broad, repeated treatment showed more weight loss than continuous. Direct dye on cotton fabric apparently inhibited hydrolysis. Ionic surfactants showed the inhibition effect of the catalytic hydrolysis of enzyme, on the other hand, nonionic surfactant did not.
