Textile colorants impart color to a textile material, usually with a high degree of permanency, as a result of their chemical binding or physical entrapment within or around the textile material. The textile material may be in one of several forms such as fiber, yarn, fabric, garment, etc. Textile colorants are supplied in both solid and liquid forms, for example, as powders, granules, solutions, or dispersions. In certain instances, precursors are applied to textile materials to generate the colorant in situ within the textile.
Textile Dyes and Pigments
Both dyes and pigments are used in the coloration of textiles . The former substances are present in solution at some point during their application, whereas the latter colorants remain insoluble within any vehicle in which they are applied as well as within the textile material itself. Pigments must therefore either be incorporated into textile fibers during their construction (e.g. mass coloration of a polymer followed...
