When polyester / cotton fabric printed with dark patterns, blending the two dyes printing required, the process is commonly used dyes, reactive dyes with paste printing. When printing, the disperse dyes, reactive dyes, alkaline agents, additives and raw paste into a paste prepared, printed on fabric, first by melt so after drying dyed polyester with disperse dyes, and then steamed to dye cotton fiber fixing. The main issues to be aware of each other staining two dyes. Impermeability of the whole water-based pigment printing control methods infiltration phenomenon will affect the pattern contour finish often. To this end, should adopt semi-emulsion pigment printing systems for decentralized twill cloth, in the printing paste printing paste is added to prevent the infiltration of improved rheological additives, such as Printrite PM (American BF Goodrich Company), to improve the synthetic thickening of the original paste printing paste flow properties, to prevent the infiltration of printing paste, reduce the permeability of printing paste. Currently cloth, the dyeing emulsion paste is also chosen as a pigment printing paste thickeners, as in the emulsion paste mechanical shearing force, which is lower than the static viscosity, when the shear force is removed, but also approximation quickly restored to the original, and therefore, a smaller emulsion paste thixotropic dispersion of polyester cloth, with a clear outline of the printing conducive pattern. However, it is a high-boiling white spirit, water, an emulsifier formed by stirring at high speed coating plain cloth, only the high cost, and release large amounts of kerosene smoke during drying or baking after printing, the odor-severe both environmental pollution and waste of energy, but also easily lead to fires. Developed less solvent or solvent-free thickener is necessary, China from the late 1970s have begun to develop the impermeability of the special paste, such as silk, Zhejiang Institute of Science have developed a special paste of impermeability, effective prevent infiltration of printing paste. It uses a non-ionic emulsifier, oil droplets dispersed as 1μm or less rapid, uniform and narrow particle size distribution of fine particles, and co-agent added, texture modifiers and the like additives, and finally adding a low resistance to solids Synthetic paste electrolyte, dubbed the impermeability of the special paste. Calico, after the official enriching cloth, twill cloth provided by dispersed after the official enriching.
