Direct Fast Black VSF Dye can be obtained in powder form as well as in liquid form. Anand Dyes & Intermediates manufactures Direct Fast Black VSF Dye.
Anand Dyes & Intermediates also manufactures wide range of dye intermediates and dyestuffs. Direct Fast Black VSF Dye is mixed in `all purpose` dyes such as Rit. The colours of direct dyes are duller than those provided by fibre reactive dyes, and the wash fastness is poor - except anything dyed with them to `bleed` forever. 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.
