Enzyme Wash is usually done on the garments made of heavy fabric like denim. For Enzyme Wash we must use cellulase enzyme. The cellulase enzyme hydrolyses the
projecting hairy cotton fabrics on the fabric surface and also removes colors. We know that Pumice Stone impact to irregular color fading effects but enzyme impact on regular color fading effect.
Steps of Enzyme Wash:
1) Desizing.
2) Bio-abrasion.
3) Back wash.
4) Additional bleaching.
5) Residual chlorine removal
6) Softening treatment.
