Coating for textile printing and dyeing and preparation method thereof
Technical Field

Background
So-called printing and dyeing printing, namely coating particles are adhered to the surface of textile fabrics through the application of adhesives, so that the coating printing and dyeing of China gradually becomes a main printing mode of blended fabrics, cotton and synthetic fibers, and occupies an important position in the global printing market. Under the condition of ever-increasing demands of people, the printing and dyeing technology is also continuously researched and applied, and the related technology needs to be mastered.
Before the actual printing and dyeing work is carried out, certain treatment such as superfine modification, dispersion and cationization of the coating is needed, so that the dye fastness, the printing and dyeing effect and the like are enhanced. In the development of work, the fine processing of paints has a very important meaning for both the color fastness and the dye uptake, and in order to obtain a stable dispersion, the application of surfactants and paint derivatives is required, i.e. the stability of the paint is improved by treating the surface of the paint. After the coating is subjected to cation modification treatment, the electrostatic repulsion can be effectively reduced, and the coating particles have dispersion characteristics and a dispersion system has higher stability.
In the case of conventional dyes, printing can be carried out by their affinity for the fibre material, whereas the pigments do not enter the fibres directly and do not have a binding force for the fibre material, because they are influenced by the particle diameter. In this regard, in the work, it is necessary to apply a synthetic resin emulsion which can improve the wash fastness, hand feeling and rubbing resistance of printed products by exerting a good adhesive effect, so to speak, a factor having a large influence on the pigment dyeing effect.
In the dyeing work, the dye binder has high requirements on the dye binder, such as the requirement of good toughness, elasticity and stability, no easy yellowing and aging in application, the requirement of a colorless and transparent coating, proper adhesive force, good chemical stability and the like, and high requirements on hand feeling and fastness.
