Abstract
The invention provides a disperse dye color paste for waterless dyeing, which comprises, by weight, 10%-40% of disperse dye filter cakes, 2%-35% of a dispersant, 5%-20% of a dyeing auxiliary, 0.1-0.5% of a surfactant, and 20%-88% of a solvent. The disperse dye color paste for waterless dyeing of the invention has a small particle size; and after waterless dyeing, a textile does not contain cleavable carcinogenic aromatic amine azo dyes, allergenic dyes, forbidden aromatic amine or bioactive substances. The disperse dye color paste for waterless dyeing of the invention can be stably stored for 6-12 months which is beneficial to the transportation of dyes and the production management of dyeing factories. Moreover, a dyeing effect featuring a high fixation rate is realized after the disperse dye color paste for waterless dyeing is applied to textiles.
