Abstract Denim garment was treated with cellulase enzyme by varying the process parameters, namely concentration of enzyme, washing temperature and time to develop novel design and fashion. The effect of process parameters on the physical and mechanical properties of cotton denim garment was investigated and denim fabric properties like tensile strength, elongation at break, weight loss, stiffness, water absorption, shrinkage, color fading and morphological values by SEM were discussed. To obtain the desired fashion effect in terms of color fading, comfort ability in terms of reducing the stiffness of denim and high wear performance in terms of longevity/minimum tensile strength losses of denim, indigo dyed denim garment (trousers, 100% cotton with twill weave 3/1 construction) had been chosen and processed with the enzyme concentration of 0.5% to 3.5%, treatment temperature from 40°C to 70°C and treatment time from 20 min to 60 min. The process parameters were optimized and the optimized washing condition for the best value is 2% enzyme concentration at 55°C for 40 min.
