Direct dyes
These dyes because they do not need to rely on other agents and direct dyes on cotton, linen, silk, wool and other fibers named. Its simple staining methods, chromatography is complete, low cost. But its poor wash fastness and light fastness, such as the use of appropriate treatment methods, can improve dye fastness of the finished product.
Reactive dyes
Also known as reactive dyes. This kind of dye is only developed 50 new dyes. Its molecular structure containing one or more active groups, under the right conditions, can react with the fiber to form a covalent bond. It can be used on cotton, linen, silk, wool, viscose, nylon, polyvinyl alcohol and other textile dyeing.
