Production and Application of Amylase Enzyme for Bio-desizing

In this study an attempt has been made to study the effect of enzyme on desizing of cotton. Cotton fabric was subjected to desizing using enzyme commercially available. An attempt has also been made, to synthesize amylase enzyme from microbe and evaluate their suitability for desizing of cotton fabrics as against the commercial enzyme. The performance of enzyme treated fabric has been compared with that of the acid desized sample. The desized samples were subjected to various tests like residual starch, iodine test, absorbency, shrinkage, breaking strength and fabric weight. The effluent after the process was analysed for pH, BOD, COD, TDS and TSS.
