Vat dyes are one of the most important dyes for dyeing and printing on cotton and cellulosic fibers. They have excellent all round fastness, which includes-washing, light, perspiration, chlorine and rubbing fastnesses. Vat dyes are insoluble in water and have to be dissolved in water by using sodium hydroxide and sodium hydrogen sulphite. The dyes are applied in a soluble, reduced form to impregnate the fiber and then oxidized in the fiber back to its original insoluble form.
