Direct Dyes is manufactured by Valia Chemicals Private Limited. The Direct Dyes are one of the two types of dyes that are mixed in `all purpose` dyes. The colours of direct dyes are duller than those provided by fiber reactive dyes, and the wash fastness is poor - expect anything dyed with them to `bleed` forever. The one advantage is that direct dyes may be more lightfast, that is, resistant to fading in the light, than fiber reactive dyes. The "direct dye" classification in the Colour Index system refers to various planar, highly conjugated molecular structures that also contain one or more anionic sulfonate group. It is because of these sulfonate groups that the molecules are soluble in water.
