The basic process of Jigger Dyeing Machine dyeing

The basic process of dyeing According to the point of view of modern dyeing theory, the reason why Jigger Dyeing Machine dyes can dye fibers and have certain fastness on fiber fabrics is because there are various gravitational forces between dye molecules and fiber molecules. The dyeing principle and dyeing process of various dyes are very different due to the characteristics of dyes and fibers, and cannot be generalized, but the dyeing process can be roughly divided into three basic stages. When the fiber is put into the dye bath, the dye first diffuses to the surface of the fiber, and then gradually transfers from the solution to the surface of the fiber. This process is called adsorption. Over time, the dye concentration on the fiber gradually increases, while the dye concentration in the solution gradually decreases, and after a period of time, an equilibrium state is reached. The reverse process of Jigger Dyeing Machine adsorption is desorption, and adsorption and desorption coexist during the dyeing process. Fixation: Fixation of Jigger Dyeing Machine dyes refers to the process in which the dyes evenly distributed on the fibers after diffusion are fixed on the fibers by the force between the dyes and the fibers.
