What is the coating dyeing process
The dyes are water-soluble and can be dissolved in water, and are reactive with the reactive groups on the fibers by the reactive groups of the dyes themselves, so that they are immobilized on the fibers. Different fibers require different types of dyes to be stained, , Need reactive dyes or direct dyes; silk fibers, need acid dyes; polyester and other synthetic fibers, need to disperse dyes.
Therefore, the paint dyeing, will significantly affect the fabric feel, there will be stiff knot. If the fabric cross-section cut to see, the fiber core is still white, no penetration. But the paint dyeing process is simple, water Less, but also has a certain special style, so, compared with the dye dyeing, each has its merits it
The paint is water-soluble, or oil-soluble. It can not dissolve itself in water, nor does it react with the fiber. It is clear that the paint used for painting and the paint of the wall are paint! The particles are large, more than a few hundred or even thousands of times the dye molecules (a particle is composed of dozens of hundreds of groups of molecules). It simply can not enter the fiber inside, can only be painted wall as painted on the appearance of cloth Also, because there is no reactive group, the coating particles can only adhere to the surface of the fabric by means of an adhesive and a crosslinking agent.
