Denim Jeans finishing is one of the most important value added activities in the washing plant to meet buyer requirements. It is done by creating numerous effects on it. Potassium Permanganate (PP) is a strong oxidizing agent used to make vintage look with acid stone wash. This present investigation deals with the simultaneous effect of processing time and concentration of PP on the physical and mechanical properties of denim garments. Three 100% cotton denim jeans were separately treated with stone acid wash with simultaneous variation of processing time (1. 5, 2 & 2. 5 minutes) and of PP concentration (1. 5, 2 & 2. 5g/l) respectively after typical enzyme bleach wash. Various physical and mechanical properties (Hand feel, Weight, EPI, and PPI, Tensile strength, Shrinkage, Seam strength, Count & stiffness) were investigated before and after each treatment according to standard test methods. It was found that change in processing time and concentration reveals big difference in various properties between treated and untreated garments.
