Sustainable Denim Washing by Process Optimization

Now-a-days sustainability is a crucial issue in denim washing. This research initiative is performed aiming to resolve the crisis of sustainability in denim washing by process optimization technique which highlights the reduction of water, chemical and time as well as costing of denim garments. In this research work, process optimization technique is administered by reducing several wash & chemical application baths into a single bath confirming without alteration of physical properties and color fastness of denim fabric. For confirmation without alteration of physical properties and color fastness, several tests are carried out like tensile and tear strength, color fastness to rubbing, color fastness to wash, color fastness to water, color fastness to perspiration and CMC (Carboxy Methyl Cellulose) value for both conventional and sustainable washing method. BOD, COD and pH of waste water is determined which shows better result in sustainable washing method also. Reduction of rinsing time in sustainable washing method results in less consumption of water by 475 and process time by 19% and also saves $0.34/ dozen garments which validate the cost effectiveness of this sustainable washing method.
