Jigger Dyeing Machine method of dyeing

The basic process of dyeing is based on the current basic knowledge of dyeing. Dyes can generally dye fibers and have a certain color fastness to washing and washing on fiber knitted fabrics. This is due to the existence of various chemical formulas between the dye chemical formula and the fiber chemical formula. The reason for the attractiveness is that the basic elements of dyeing and the dyeing process of various dyes are very different due to the characteristics of dyes and fibers. They cannot be generalized, but the dyeing process can probably be divided into three Basically link. After the fiber fund manages the dye bath, the dye first spreads to the fiber surface, and then slowly migrates from the aqueous solution to the fiber surface. This process is called absorption. With the change of time, the dye concentration value on the fiber slowly increases, while the dye concentration value in the aqueous solution slowly decreases. After a period of time, the equilibrium state is ensured. The reverse process of absorption is analysis, and absorption and analysis exist in addition to the dyeing process. Contact inhibition: The contact inhibition of the dye refers to the process in which the dye spreading uniformly on the fiber is inhibited on the fiber according to the interaction force between the dye and the fiber.
