What You Should Know About Vat Dyes
Originally, cellulosic fibers like cotton fibers were dyed with vat dyes. Vatting is the fermentation process by which these colors are solubilized in a vat. Vat dye is used to impregnate the fiber in a soluble, deteriorated condition. It then undergoes oxidation in the fiber, returning to its original, insoluble state. Vat dyes have a weak rubbing fastness and a good color fastness. One typical and important type of vat dye is indigo. Vat dyes react quickly to light and washing in particular. The vat dyes market size is expanding more quickly than in previous years, and it is anticipated that the market will expand significantly between 2023 and 2030, the expected period.
These colors are used to dye cotton when high wash and boil fastness is required. Due to the high alkali concentration in the dye bath, pure vat dyes have limited application in animal fibers. A reducing agent is required to solubilize vat dyes. A potent reducing agent, such as hydrosulfite, is used to reduce it to a soluble form. Vatting, coloring, and oxidizing are the several phases of vat dyeing. The market offers a variety of vat dye colors.
