Acetate fibers are dyed usually with disperse dyes specially synthesized for these fibers. They tend to have lower molecular size (low and medium energy dyes) and contain polar groups presumably to enhance the forces of attraction by hydrogen bonding with the numerous potential sites in the cellulose acetate polymer (see Fibers cellulose esters). Other dyes can be appHed to acetates such as acid dyes with selected solvents, and azoic or ingrain dyes can be apphed especially for black colorants. However thek use is very limited. 

Dyes are also classified on the basis of their application. The water-soluble dyes which are the salts of sulfonic acid or phenolic compounds are named acid dyes] those which are the salts of amino compounds are called basic. If the dyeing is accomplished without use of mordants the dyes are called direct. Dyes which require the use of metallic oxides, tannin, and other substances to give fast shades are called mordant dyes. The water-insoluble dyes are known as vat dyes. The insoluble colored substance is reduced in a fermentation vat or by hydrosulfite to a soluble form which is applied to the fiber then oxidized by air to the insoluble color. Finally ingrain dyes are produced by performing one or more of the chemical reactions used for the preparation of the dye directly on the fiber.

For dyeing and printing of cotton a multitude of dyes with totally different chemical structures are available. Substantially the dyestuffs for cotton are classified in direct, reactive, sulfur and ingrain dyes and pigments for printing. All these dyes need for their application special auxiliaries and conditions. 

The categories marked ( ) are not classified as to chromophore since sulphur dyes for example are mixtures of indeterminate structures and azoic and oxidation bases are Ingrain dyes (section 2.4.2.8) and are sold as components, the final dye being produced on the substrate by chemical processes.
