Jigger Dyeing Machine Dyeing Method

The basic process of dyeing According to the current basic knowledge of dyeing, dyes can generally dye fibers, and have a certain degree of color fastness to washing and washing on fiber knitted fabrics, because there are various differences between the chemical formula of the dye and the chemical formula of the fiber The reasons for the same attractiveness, the basic dyeing elements of various dyes and the dyeing process are very different due to the characteristics of the dyes and fibers, and cannot be generalized, but in terms of the dyeing process, they can be roughly divided into three Basically link. After the fiber material enters the dye bath, the dye spreads to the surface of the fiber first, and then slowly migrates from the aqueous solution to the surface of the fiber. This process is called adsorption. With the change of time, the dye concentration on the fiber gradually increases, while the dye concentration in the aqueous solution gradually decreases, and after a period of time, a balanced state is achieved. The reverse process of adsorption is decomposition, and adsorption and decomposition exist in addition to this in the process of dyeing. Contact inhibition: The contact inhibition of dye refers to the process that the dye spread evenly on the fiber is contact inhibited on the fiber according to the interaction force between dye and fiber.
