What are the functions of printing paste in production?

　　There are four functions of printing paste in the printing process:

　　(1) As a thickener of printing paste, the printing paste has a certain viscosity, which partially offsets the infiltration caused by the capillary effect of the fabric, thus ensuring the outline smoothness of the pattern.

　　(2) As a dispersion medium and diluent for dyes, chemicals, auxiliaries and solvents in the printing paste, all components in the printing paste can be uniformly dispersed in the original paste and diluted to a specified concentration to make the printing paste.

　　(3) As a transfer agent of dyes, it acts as a carrier. When printing, the dye is transferred to the fabric with the help of the original paste, and after drying, a colored paste film is formed at the pattern. When steaming, the dye is transferred through the film and diffused into the fabric, and the transfer amount of the dye varies depending on the type of paste.

　　(4) Used as an adhesive. The original paste must have certain adhesion to the flower tube to ensure that the printing paste is paid in the concave pattern of the flower tube. When printing, the color paste is squeezed by the cylinder and the pressure roller, so that the color paste can stick to the fabric. After drying, the colored paste film on the fabric must have great drilling ability to the fabric and not fall off from the fabric.
