Abstract

The invention discloses a direct printing process for polyester fabric. The direct printing process includes steps: S1, performing quality detection and antistatic treatment on the polyester fabric; S2, pretreating the polyester fabric; S3, sizing the polyester fabric; S4, subjecting the polyester fabric to water washing: utilizing a water washing agent for water washing of the polyester fabric after being aged; S5, winding the polyester fabric onto a hanger to make a flat net screen, and performing scrape-coating and size-pulling on a flat net to form a size drawing board on the surface of the polyester fabric; S6, spraying the surface of the polyester fabric through a digital printing machine, and cooperating with the size drawing board for direct printing on the surface of the fabric; S7, taking the fabric down from the hanger, and shaping and air-drying the polyester fabric. The direct printing process can realize quick printing and is good in printing effect, soft and vivid in printing, high in color fastness after printing is completed and long in printing life.

Description

technical field [0001] The invention relates to a printing process, in particular to a polyester fabric direct printing process. Background technique [0002] With the continuous improvement of living standards and the advancement of technology, people have higher and higher requirements for textile fabrics, especially polyester fabrics. These fabrics must not only meet the advantages of high softness and comfort, but also meet a considerable degree of decoration. sex and aesthetics. [0003] At present, the direct printing process of polyester fabrics existing on the market is relatively simple, usually using the screen printing method, including flat screen printing and rotary screen printing. Printing and dyeing after the garment is finished, the color difference is large and the hand feels relatively hard; the color fastness and stability are not good, and the printing time is very long. [0004] Therefore need to design a kind of direct printing process of polyester f...
