The evolution of the jean’s market led to the development of some unique and creative methods for the processing of denim garments. Originally, jeans were marketed and sold as work wear, but when jeans appreciated by consumers as general casual wear, they became fashionable and new techniques were developed to enhance denim garments.

The first generation of indigo jeans was stiff and uncomfortable when first purchased, due to the finishing techniques used for denim fabrics. The second generation of the jean’s market evolution produced pre-washed jeans by the manufacturer. These jeans had a slightly faded appearance and a softer hand that felt comfortable.Not long after the introduction of pre-washed jeans, the idea of using abrasive stones to accelerate the aging process was developed and "stone washing" was born, creating an even more "broken-in" look. Next, chlorine bleach was incorporated in these wash techniquesice washing was developed, in which the porous stones are soaked in a bleaching agent and then tumbled with dry or slightly damp garments.

Most recently, a cellulase wash procedure was developed in which cellulase enzymes were used to accelerate color and fiber removal. This process can be more efficient, since with fewer stones. These garment washing techniques were originally developed for denim garments, but are now being used for a wide variety of different garment types. This technical article describes the basic wash, stonewash, stonewash with chlorine, ice wash, and cellulose wash techniques used for cotton garments. Any of these procedures can be modified to fit a particular situation, depending upon garment type, available equipment and process flow.
