Direct Blue Dyes For Cotton
Direct blue dyes have water-soluble groups such as sulfonic acid group (-SO3H) or carboxyl group (-COOH) arranged in linear molecular structure.
The aromatic ring structure is in the same plane, so the direct dye has a greater affinity for the cellulose fiber.
It can be dyed directly in a neutral medium. As long as the dye is dissolved dry water, it can be dyed.
