A novel approach to sustainable denim wash: study on effect of low water ratio bio-washing on denim fabric shade

Abstract

In comparison to other manufacturing industries, the textile denim business has a very high water footprint. We develop a unique washing recipe within acceptable shades to provide a sustainable washing technique that will limit the wasteful consumption of water. We investigated bio-polish and bio-magic enzyme on three types of fabric samples and discovered that bio-magic uses very little water as bio-polish while producing a shade that is identical to bio-polish. We do mechanical tests and observe that after bio-magic treatment, all fabrics lose a disproportionate amount of weight and have a significant loss of tear and tensile strength. This is owing to the fact that simultaneous enzymatic and mechanical action happens within the machine during bio-magic treatment. Colorfastness to crocking, dimensional stability to washing and skewness are all taken into consideration. Denim fabric washed with bio-magic: a neutral lipase enzyme based on Humicola presents long-term possibilities for the denim business.
