Effect of Processing Time and Concentration of Potassium Permanganate on Physico-Mechanical Properties of Denim Jeans During Stone Washing

Authors: Elias Khalil

Three 100% cotton denim jeans were treated with stone acid wash with the variation of processing time (1.5, 2 & 2.5 minutes) and concentration (1.5, 2 & 2.5g/l) of potassium permanganate 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 (concentration and respective time) 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.
