The printed fabric is a kind of fabric in which the printed pattern is printed after the fabric is woven. The printed fabric is different according to the different printing materials and the different printing processes.

The fabric must be pretreated before printing to make it have good wettability. The dyes used in printing are basically the same as those used in dyeing, and some smaller patterns can be painted.

Different types of dyes can be used to print patterns in various colors on the same fabric. When printing, the dyes or pigments are mixed into color pastes. After printing and drying, it is usually steamed, developed or fixed, and then soaped and washed to fully remove the paste, chemicals and floating color in the color paste.

The printing paste is composed of dye, moisture absorbent, cosolvent, etc. and the original paste. The function of the original printing paste is to make the color paste have a certain viscosity and fluidity. It is prepared from a hydrophilic polymer paste. The commonly used pastes include starch, starch degradation products, starch ether derivatives, sodium alginate, hydroxyethyl acacia gum, dragon gum, cellulose ether, and synthetic polymers. Electrolyte, etc. The emulsified paste made with water, kerosene and emulsifier is sometimes used as the original printing paste. The original printing paste should have good stability to the chemical agents in the color paste, does not interact with the dye, has a certain adhesion to the fiber and is easy to wash off the fabric. The viscosity of the printing paste is determined by the nature of the original paste. When printing, if the viscosity of the color paste drops too much, it will be difficult to print fine lines, and if the viscosity is too large, the color paste will not easily pass through the pores of the screen.
