what is solvent dye?
Solvent dye is most suitable for various plastic materials coloring, with greater color strength, better fastness to heat, light, acid and alkali. This range of Solvent dye is generally used in coloring domestic plastic materials, cop tube materials, fat dyeing, lacquers, inks and master batches dyeing. Some of Solvent dye is suitable for dyeing chemicals fiber, such as dacron, nylon and cellulose acetate fiber. Solvent dye has good solubility and miscibility in organic solvents.
Disperse Dyes are derived from anthraquinone. The particles of vat dyestuffs in this form have been ground to extremely small size with the help of most modern techniques. These powders are easily dispersable and are suitable for dyeing cotton yarns packages and cotton piece goods by batch wise and continuous dyeing methods. It can be used for exhaust dyeing as well.
Reactive dyeing is now the most important method for the coloration of cellulosic fibres. Reactive dyes can also be applied on wool and nylon; in the latter case they are applied under weakly acidic conditions. Reactive dyes have a low utilization degree compared to other types of dyestuff, since the functional group also bonds to water, creating hydrolysis.
