Direct dyes


Direct Dyes, which directly dissolve in water, have a high direct property of cellulose fibers, without the use of chemical methods to make fibers and other materials colored. Direct Dyes can be in weak acidic or neutral solution of protein fibers such as wool, silk) color). It is also used to dye cotton, linen, silk and rayon. Chromatography is complete, the price is low, the operation is convenient. The disadvantage is washing, light fastness is not ideal.

The molecular structure of the direct dyes with sulfonic acid group or carboxyl group arranged in a straight line. Aromatic ring structure is in the same plane,

Therefore, the direct dyes on cellulose fibers with a greater affinity, in the neutral medium, the direct staining, as long as the dye dissolved dry water, they can be stained.

The dye is adsorbed onto the surface of the solution, and then spread to the amorphous region of the fiber, and the formation of hydrogen bonds and Fan Dehua forces with the fiber molecules.

The derivative dyes have direct dyes and direct dyes copper salt.
