TECHNOLOGY OF ACID WASH ON WOVEN DENIM APPAREL WITH DAMP PUMICE STONE

Abstract: Now-a-days the woven denim apparel has achieved the highest level of popularity. The denim trend is accepted by anyone from fashion concern to unconcern personality. Faded denim is one of the most well-liked fashions to today’s youth. The aim of this work was to study the technology of acid wash with damp pumice stone on woven denim apparel (jeans)of 100 % cotton indigo dyed, 3/1 twill weave. The effect of acid wash on jeans also investigated. The jeans were processed with damp pumice stone (400%) (owm) at room temperature for 15 min without additional water. Phosphoric acid (1ml/l) and potassium permanganate (4gm/l) were used for soaking the pumice stone at room temperature for 10 min by shuffling. It has been explored that acid wash treatment is very effective for woven denim apparel to create an irregular fading effect. The properties of denim that were inspected contained breaking strength, stiffness, GSM, dimensional changes (shrinkage / growth %) count, EPI & PPI and color change. Obtained results were compared and found that breaking strength, stiffness, GSM, dimensional stability, colour depths are decreased. But count, EPI & PPI is increased for acid wash treatment on woven denim apparel
