About Industrial Dyes
Industrial dyes are colorants consisting of single molecules that are able to absorb certain parts of the spectrum of visible light and reflect others. Dyes are soluble in the material in which they are dispersed. Dye can generally be described as a colored substance that has an affinity to the substrate to which it is being applied. The dye is usually used as an aqueous solution, and may require a mordant to improve the fastness of the dye on the fiber. Industrial dyes are obtained from animal, vegetable or mineral origin, with no or very little processing. There are many types of industrial dyes. Examples include acid dye, chemical dye, leather dye, dispersed dye, and textile dyes. Acid dye is a water-soluble anionic dye that is applied to fibers such as silk, wool, nylon, and modified acrylic fibers. Chemical dye is prepared from various chemical substances and is generally used for preparing industrial dye tints. Dispersed dye is substantially water insoluble. It is finely ground in the presence of a dispersing agent and then sold as a paste. Leather dye is specially formulated to color leather items. The covalent bonds that attach leather dye to natural fibers make it among the most permanent of dyes. Other industrial dyes are commonly available.
