Abstract

The effect of enzyme treatment using neutral cellulase on the colour fading property of cotton denim fabric manufactured by conventional ring-spun and torque-free ring-spun yarn was studied. Four cellulase processing parameters namely treatment temperature, treatment time, pH value and agitation were considered. In order to investigate the optimum condition for the neutral cellulsae treatment, an orthogonal analysis was used and, based on the colour fading percentage (CF%), the optimum condition for cellulase treatment on conventional ring-spun yarn made denim fabric was treatment temperature = 55°C; treatment time = 60 minutes; pH value = 8 and agitation = 100 steel balls (simulated vigorous agitation) for the best colour fading achievement with desired worn and aged effect. While the optimum condition for cellulase treatment on torque-free ring-spun made denim fabric was treatment temperature = 50°C; treatment time = 30 minutes; pH value = 8 and agitation = 50 steel balls (simulated mild agitation) for achieving best colour fading effect. Meanwhile, the level of importance based on the orthogonal analysis of the two types of fabric was not the same.
