| Abstract: | The optimum conditions for surface modification of polyamide 6 (PA) by protease enzyme produced by Bacillus isolate 16P have been studied. These conditions are found to be 0.05 mg/mL enzyme concentration, 0.5 h treatment time, room temperature (30ºC) and pH 8 under shaking conditions. The effect of hydrolytic activity of enzymatic process on the weight loss of PA fabric after enzymatic treatment shows negligible difference. Printing both untreated and treated PA fabrics with transfer printing shows high leveling properties as regard to ∆E values which are considered as acceptable values of color differences. PA treated with different sources of protease enzyme under optimum conditions shows good physical properties. SEM of the surface of protease treated PA samples shows etches and voids compared to smooth surface of untreated PA fabric. |
