Abstract

Recently, indigo dyed denim garment washing is an indispensable process for producing fashion items for leisure wear. To achieve different fading effects and an aesthetic look, several techniques are used. In this research, acid wash was performed in the presence of phosphoric acid (H3PO4) (0.5-2.5gm/l) to obtain better fading effect as well as physical properties and draw a conclusion of optimize acid amount. Owing to the change in acid concentration, variations in the fabric’s physical and mechanical properties like strength, weight loss, GSM, EPI, PPI, dimensional stability and absorbency were observed. Furthermore, color abrasion values such as Color Measurement Committee (CMC), Color strength (K/S), yellowness, whiteness values as well as color fastness properties of the fabrics were also evaluated. From the experimental results, 2gm/l of phosphoric acid was most effective at removing color from denim fabric, producing a good acid washing effect with lowest hydrolysis level of the fibers.
