This article discusses the enzymatic decolorization of denims. Denim is considered as the most popular fabric worldwide. Denim fabric is made from 100 per cent cotton yarns. Specialty of the denims is that only warp yarns are dyed and weft yarns are white. The processing of denim fabrics has become more or less simple and routine. Processing includes wetting, desizing, biofading, bleaching and softening. The general aim of processing the denim garments is to remove size from the fabric and also to remove indigo dye. Nowadays, people have become more environmental conscious. In these circumstances, processors are looking for ecofriendly alternative chemicals for processing. In denim garment processing, enzymes are used for desizing and giving an abrasion look. Being biodegradable, enzymes are eco-friendly. Enzyme is also used to decolorize indigo. The process of enzymatic decolorization is discussed.
