Disperse Blue dyes, especially 106 and 124, are common causes of contact allergy. [6] Disperse Orange 1 is an azo dye. Disperse Red 9 is a red dye derived from anthraquinone. Disperse Red 11, also called C.I. 62015 and 1,4-diamino-2-methoxy anthraquinone, is another anthraquinone dye. Disperse Red 60 is also an anthraquinone dye.
The disperse direct ink is a ‘stronger’ ink than the dye-sub kind, and this is very important for outdoor use, such as for fence fabric, flags and banners: artwork will last longer. Another benefit of aqueous-based sublimation ink is the absence of hazardous components as found in UV-curable, solvent and, even, in latex inks.
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.
Since the early 1990s, inkjet technology and specially developed water-based ink (known as dye-sublimation or disperse direct ink) have made it possible to print directly onto polyester fabric. This is mainly related to visual communication in retail and brand promotion (flags, banners and other point of sales applications).
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 ...
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]
