Modification of Cotton Fabrics Treated with Cellulase

Cotton fabrics were treated with cellulase at 50℃, pH 4.5 with varying concentration and treatment time. Treated fabrics were evaluated for weight-loss and performance properties. Moisture regain and dye adsorption were measured to investigate microstructural change and SEM analysis for morphological change. Effect of cellulase treatment before and after DP finishing was studied by measuring the change of performance properties. As cellulase concentration and treatment time increased, weight-loss increased, strength decreased, and softness increased Moisture regain and dye adsorption decreased, and etchings and cracks on the fiber surface were developed with the increase in weight-loss. Cellulase treatment before DP finishing was more efficient compared with cellulase treatment after DP finishing for improving softness.
