dc.description.abstractMaize starch samples have been subjected to gelatinization at 70°C followed by enzymatic treatment using different concentrations of α-amylase enzyme (0.025, 0.050, 0.075 and 0.1 mL/50g starch) and then used in printing paste as thickener for discharge, discharge-resist and burn-out printing on cotton, wool/polyester and viscose/polyester/lucre fabrics. The results show that enzymatic treatment of maize starch converts the rheological properties of starch from thixotropic into pseudo-plastic. Increase in α-amylase enzyme concentration is accompanied by a decrease in the apparent viscosity. While enzyme-treated starches give better results when used as thickening agent in discharge-resist printing compared with sodium alginate, the opposite holds true in case of discharge printing. Enzyme-treated starches specially that prepared using 0.1 mL/50g starch could act successfully as thickening agent in burn-out printing of both wool/polyester and viscose/ polyester/lucre blends. en_US
