> Application of Indigo Blue

Vat dyes are widely used for colouring cellulosic fibre, especially cotton fibre along with viscose rayon, leather and other fibres.

Indigo Blue is the most used vat dye as it becomes the base for dyeing denim fabrics. Apart from that it can also be used in blend like polyester/cotton blend e.g. t-shirt in the second bath for dyeing the cotton fibre. But because of the high alkali concentration required for the dye bath, pure vat cannot be used on animal fibres (wool, natural silk, and various hairs).
