Direct Dyes

Product Description :
Direct dyes are another class of dyes, one of the two types of dyes that are mixed in 'all purpose' dyes such as Rit. The colors of direct dyes are duller than those provided by fiber reactive dyes, and the wash fastness is poor - except anything dyed with them to 'bleed' forever. The "direct dye" classification in the Color 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. Though most direct dyes still can be obtained in powder form, it is increasingly popular to receive them as liquid concentrates.
