Abstract: Laccase enzyme formulation has been used in discharge printing of cotton fabrics dyed with different reactive dyes and the effect of enzyme conc., pH of the printing paste, treatment time and temperature of enzymatic treatment as well as the viscosity of the printing paste on colour discharge studied. The optimum conditions for discharge printing are found to be 4.5 pH, 60ºC temperature, 1 h time of treatment, and the 90.4 poise viscosity at a shear rate of 31.61s⁻¹. The concentration of enzyme depends on the nature of dye used.
