There are continuous efforts to replace harsh chemicals with enzymes in textile processing. Cellulase is a commonly used enzyme for processes such as bio-finishing, bio-polishing and softening of cotton fabrics. The term enzymatic effect is used to account for the changes in the molecular structure of cotton fabric brought about by the cellulase enzyme as monitored by activity of the enzyme, loss in fabric weight, tensile strength and elongation at break, as well as the color strength of the enzymatically treated fabric when dyed with reactive dyes. Dependence of the enzymatic effect on...
