ABSTRACT: 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.
