The printing process is a process in which dyes or pigments are used to imprint patterns on textiles. Printing is divided into textile printing, wool top printing, and yarn printing, and mainly textile printing. Top printing is used to make mixed-color tweed; yarn printing is used to weave special-style colorful pattern fabrics. Fabric printing has a long history. In the Warring States Period, China had already used hollow-out printing. India had printed wood stencils in the 4th century BC. Continuous gravure cylinder printing began in the 18th century. Screen printing is developed from the hollow pattern, which is suitable for small batch and multi-variety printing of easily deformed fabrics.
The printed fabric is an artistic product, and the corresponding printing process is selected according to the design pattern. There are three commonly used direct printing, anti-dye printing, and discharge printing. Direct printing is to directly print dyes or pigments on white or light-colored fabrics and then after steaming and other post-processing to obtain patterns, the process is short and the most widely used. Anti-dye printing is a substance printed on the fabric to prevent dyeing or color development of the dye, and then dyeing or coloring, so as to obtain a pattern on the dyed fabric. Discharge printing is a printing process that prints on dyed fabrics to eliminate dyes and obtain patterns on dyed fabrics.
