(Piece) - Dyeing of the fabric into solid colors after weaving or knitting.
(Yarn) - Dyeing of the yarn into solid colors before weaving or knitting.
A colorant that has substantively (q.v.) for a substrate, either inherent or induced by reactants.
A dye can generally be described as a coloured 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 fibre. In contrast, a pigment generally has no affinity for the substrate, and is insoluble.
A colorant that becomes molecularly dispersed at some point during application to fiber and exhibits some degree of permanence. There are many application classes of dyes, including acid dyes, disperse dyes, reactive dyes, and natural dyes. Dyes may be generally divided into natural and synthetic types. Natural dyes are obtained from berries, flowers, roots, bark and more. Synthetic dyes are chemical compounds.
