Washing of Denim garment with pumic stone combined with bleaching powder was investigated to preserve the quality and to create more distress worn-look fashionable Denim garment. For this, regular Denim trouser (twill 3/1 weave, composition 100 % cotton) was selected for the present investigation. The Denim trouser has been processed by stone-bleach washing technique, using various concentrations of pumice stone (10 to 70%) (owg) with 10 g/L bleaching powder at 40 ⁰C for 20 min. In order to evaluate the influence of pumice stone on physico-mechanical properties like tensile strength, elongation at break, fabric weight, colour change, the dimensional characteristics (shrinkage/ extensibility), stiffness and water absorption has been determined. Fabric surface was also examined by scanning electron microscope (SEM). It can be concluded that pumice stone made the influence on Denim properties, whereas in producing durable and distressed worn look Denim garment the optimised washing condition for the best value is determined.
