Abstract
Nowadays, textile processing based on biotechnology has gained importance in view of stringent environmental andindustrial safety conditions. The best established application of biotechnology to textiles is the use of enzymes. These vital parts of all living organisms are organic catalysts with specific in the reaction catalyzed and substrates selectivity. The main enzymes used in textile processing are amylases, cellulases, proteases, esterases, nitrilases, catalases, peroxidases, laccases and pectin-degrading enzymes. Many research papers have been published on surface hydrolysis of polyester using enzymes and its dyeing behavior but few of them have been reported on dyeing of hydrolyzed polyamide. Thus, in order to fulfill further studies in dyeing behavior of enzyme treated polyamide, the present research work focuses on the physical and chemical properties of acid and disperse dyed-protease treated nylon 6 fibers.
Keywords: Subtilisin; Nylon 6; Biohydrolysis; FTIR
