A dye that is slightly soluble in water and highly dispersed in water by the action of a dispersant. Disperse dyes do not contain water-soluble groups and have low molecular weight. Although the molecules contain polar groups (such as hydroxyl, amino, hydroxyalkylamino, cyanoalkylamino, etc.), they are still non-ionic dyes. This kind of dye has high post-treatment requirements, and usually needs to be ground by a grinder in the presence of a dispersant to become highly dispersed and stable crystal form particles before use. The dye solution of disperse dyes is a uniform and stable suspension. Disperse dyes were produced by the Baden Aniline Soda Ash Company in Germany in 1922 and are mainly used for dyeing polyester fibers and acetate fibers. At that time, it was mainly used for the dyeing of acetate fiber. After the 1950s, with the emergence of polyester fiber, it developed rapidly and became a major product in the dye industry.
