The process of partially coloring fabric with dye or paint to form patterns or patterns is called fabric printing. The production of Printing Pile Fabric generally includes four processes: screen plate making (or cylinder engraving), color paste preparation, pattern printing and printing post-treatment.

Printing, like dyeing, makes dyes and fibers dye. The difference is that when dyeing, the fabric is fully and evenly dyed with dyes, while when printing, dyes of a certain color only dye certain parts of the fabric, thus causing the fabric to present patterns of various colors. In order to obtain various pattern patterns on the fabric and achieve the purpose of local dyeing, printing cannot be carried out in the dye liquor like dyeing, but the paste must be prepared into the original paste as the dye carrier, then the dye and necessary chemical additives are added to prepare printing paste and printing on the fabric, so as to overcome the infiltration phenomenon of dye liquor and obtain the required pattern patterns.

After the printing color paste is printing on the fabric, in order to transfer the dye from the color paste, dye it onto the fiber and complete a certain chemical reaction, it also needs to undergo post-treatment processes such as drying, steaming (or compensation drying), flat washing, etc. to transfer the dye from the color paste onto the fiber and diffuse it into the fiber to complete the process of dyeing the fiber with the dye. After sufficient washing and soaping, the paste and floating color on the printing plush fabric are washed out, thus obtaining the printing plush fabric with bright color and good color fastness.

Direct printing is most commonly used for printing plush fabrics. The dyes used include reactive dyes, vat dyes, soluble vat dyes, insoluble azo dyes, stable insoluble azo dyes, phthalocyanine dyes, etc. Besides direct printing, there are also anti-dye printing, discharge printing and anti-discharge printing.
