The demand of chemical treatment on denim fabric to create a new look is increasing day by day. Now- a -days biochemical wash has become a trendy choice to customer. Manufacturers are in a rush to fulfill the demand of customer. They also are to take in consideration the quality of the product after the treatment. So This paper represents and compares the effect of biochemical wash on woven denim fabrics by means of GSM (gram per square meter) measurement, shrinkage test, count measurement, EPI & PPI measurement, comparison of color depth, air permeability test, rubbing test & hand feel test. Acid enzyme was used as a biochemical for the treatment. Treatment increases the GSM of woven denim apparels. Dimensional change is occurred due to enzyme wash. Lengthwise shrinkage can be ignored but widthwise shrinkage should be taken in concern. There is little effect on EPI & PPI due to enzyme wash on woven denim apparels. Enzyme wash decreases the depth of color on woven denim apparel. Air permeability also becomes lower due to treatment. Finally with the increase of time hand feel i.e. the apparels become softer due to enzyme wash.
