| Abstract | ||
| This work focused on discharge printing on denim fabrics, which dyed with reactive or indigo dyestuff, using an oxidizing agent, KMnO4. Factors of printing process will be studied, different concentrations of the discharging agent and different pH values. Whiteness and color strength for all tested samples will be measured to determine the best optimum and conditions for each process. Tensile strength will also be measured to ensure suitable outcome that does not effect on the fabric's tensile strength. The processed samples will be subjected to FT-IR to clear identify any changes that may have occurred in the dye molecule. | ||
