Definition

Dyeing can be described as the uniform application of colorant(s) to a coloring medium. The coloring of textiles may involve mass pigmenting (involving compounding), dyeing, and printing processes. The coloring medium in textile dyeing may take different physical forms (such as loose fiber, yarn, tow, top, woven, nonwoven and knitted substrates in open width or rope form), whereas in printing colorants are added to selected regions of the medium which is usually in a fabric form. Dyeing of homogenous fibers should result in a uniform solid color. Multicolored effects may be obtained by dyeing a blend of different fibers, bi- or multicomponent synthetic fibers, or via multiple colorant or illuminated discharge printing. In a technique known as space dyeing, colorant(s) can be applied from nozzles that inject different dyes to yarns and force steam in the vessel, thus generating a multicolored pattern.
