Disperse dye is a category of synthetic dye intended for polyester and related hydrophobic fibers. Disperse dyes are polar molecules containing anthraquinone or azo groups. Disperse dyes are polar molecules containing anthraquinone or azo groups.
Disperse Yellow 42, or 4-anilino-3-nitrobenzenesulfonanilide, is a disperse dye that is primarily used to dye polyester fibers. It is prepared by the reaction of two equivalents of aniline with 4-chloro-3-nitrobenzenesulfonyl chloride. An estimated 10,000 tons were prepared in 1990, making Disperse Yellow 42 the nitro dye produced on the ...
Polyester fabric is printed mostly with dye-sub or disperse direct ink, although UV and solvent inks (including HP's latex formulation) can also be used. The great benefit of sublimation ink is the fact that the colorants will bond with the fibre during sublimation or fixation.
Disperse Red 11, or 1,4-diamino-2-methoxyanthraquinone, is a red disperse dye derived from anthraquinone. [1] [2] [3] It is water insoluble.[1]Disperse Red 11 can be used in plastics and textiles industry to dye polyvinylchloride, polyester, polyamide, and polyurethane materials, such as synthetic fibers and foams.
Combinations of cold water-soluble carboxymethylated starch, guar gum and tamarind derivatives are most commonly used today in disperse screen printing on polyester. Alginates are used for cotton printing with reactive dyes, sodium polyacrylates for pigment printing, and in the case of vat dyes on cotton only carboxymethylated starch is used.
Disperse dyes were originally developed for the dyeing of cellulose acetate, and are water-insoluble. The dyes are finely ground in the presence of a dispersing agent and sold as a paste, or spray-dried and sold as a powder. Their main use is to dye polyester but they can also be used to dye nylon, cellulose triacetate, and acrylic fibers.
Disperse dyes are used to color textiles. Disperse blue dyes are used to produce blue and other dark colors. Like other disperse dyes, they are only slightly soluble in water. [1] However, they can be a source of water pollution. [2] Disperse blue dyes, especially Disperse Blue 106 and Disperse Blue 124, have a higher than usual prevalence of ...
This range contains a mixture of 3 different dyes - direct, acid and disperse. Direct dyes are for cellulose based fabrics, acid dyes for wool and nylon and disperse for some plastics. None of these are reactive dyes and are less wash fast than the other ranges. It comes in 26 colours. [3]
