Application of Enzymes in Textile Industry - Creative Enzymes

Enzymes can be used in catalytic concentrations at low temperatures and at pH-values near to neutral. Thirdly, enzymes are the best alternative to toxic, hazardous, and polluting chemicals. Fourthly, enzymes act only on specific substrates, for example, enzymes used in desizing do not affect cellulose hence there is no loss of strength of cotton.
