It is the process of reduction of denim products
to a very light blue color. Since too much hypo or permanganate is used to
reach the desired color, the neutralization procedure must be done very well.

be weakened. In such a wash, the risk of reeling is greater than in other
Because of this, it is necessary to pay attention to the conditions of presentation and storage for ice-washed products. The accessories used in these products are affected badly due to excessive hypo usage and cause rust and stain problems. Ice washing, which causes lycra deterioration in lycra fabrics, is made using permanganate in these types of fabrics.
