Definition of Direct Dyes are molecules that adhere to the fabric molecules without help from other chemicals.Direct dyes are also known as substantive dyes.
Direct dyes are water-soluble dyes usually of the azo class that is used in alkaline or impersonal solution especially for dyeing cellulosic material directly. Direct dyes are used on cotton, paper, leather, wool, silk, and nylon. 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 dyes” classification in the Color Index system refers to various planar, highly conjugated atomic structures that also contain one or more anionic. After various after treatments are used to improve the wash fastness of direct dyes exporters, and such dyes are referred to as “after treating direct colors.” Direct Dyes are molecules that adhere to the fabric molecules without help from other chemicals. Direct dyes give bright shades but exhibit poor wash fastness.
