Degrading Enzymes

Enzymes including starch-degrading enzymes and glucose oxidase are used in one-bath process to desize and bleach cotton fabrics. The effect of enzyme concentration on pretreatment efficiency, especially bleaching of cotton fabrics has been investigated by innovatively focusing on glucose conversion ratio of desizing products. The results showed that the starch sizing materials of cotton fabrics were completely removed by starch-degrading enzymes. The conversion ratio of glucose in desized liquor increased with concentration of glucoamylase. Consequently, whiteness of cotton fabrics bleached in one-bath process was also improved, and an increase of 7% in whiteness of bleached fabrics was observed. The fabric tear strength was decreased. However, the loss ratio could be controlled below 15%. The properties of softness and adsorption of bleached cotton fabrics were satisfactory.
