[0004] However, the pretreatment of the gray cloth in this invention only involves simple desizing, bleaching, and setting. Such gray cloth is likely to shrink when it encounters water after printing the finished garment, thereby causing irregular changes in the printed pattern and reducing the printing quality.

Embodiment 1
[0045] Embodiment 1: a kind of woven cloth dispersion printing technique, as figure 1 The woven cotton fabric shown was treated as follows:
[0046] A. Turn over the cloth, turn the accepted cloth into the cloth cart, and each cloth pulls out 2-3 meters of cloth head for jointing;
[0047] K. Singeing, use the singeing machine to singe the cloth, burn off the hair on the surface of the cloth, and bleach the cloth after the singeing is completed. The bleaching process is to immerse the cloth in oxygen-containing bleaching agent, and the bleaching temperature is controlled. At 85°C, the bleaching time is 15 minutes; oxygen-containing bleaching agents include hydrogen peroxide, color bleaching powder, and oxygen bleaching stabilizers, and oxygen bleaching stabilizers include 8 parts of magnesium sulfate, 5 parts of aminoethanol phosphoric acid, 5 parts of picolinic acid, and 2 parts EDTA complexing agent; after the cloth is bleached, it needs to be soaked in caustic soda solutio...

Abstract
The invention relates to the technical field of printing and dyeing, and discloses a woven fabric dispersed printing process. The process comprises the following steps: A, fabric turning, turning theaccepted fabric into a cloth car, drawing 2 to 3 meters of fabric scraps for the fabric; B, pre-shrinking, pre-shrinking the fabric by a pre-shrinking machine; C, scutching, using a scutching machinefor scutching the fabric obtained in step B to expand the fabric; D. rolling, wind the original fabric after scotching to a fabric roll; E, printing, taking disperse dye, printing the fabric roll using a rotary screen printing machine; F, steaming, steaming the fabric after the printing in step E by using a steaming machine; G, washing with water, placing the fabric obtained in step F in a washingmachine for washing, and removing the color paste, paste, chemicals and dyes remaining on the fabric; and H, finished product fixing, and drying the fabric obtained in step G by a hot baking fixing machine and fixing. The process pre-shrinks the fabric after the fabric is turned over, so that the fabric shrinks in the subsequent process without water, and the printing quality is ensured.
Description
technical field [0001] The invention relates to a dispersive printing process for woven fabrics, belonging to the technical field of printing and dyeing. Background technique [0002] Disperse printing is a kind of dye printing, which refers to the method of printing with disperse dyes. Dispersion printing is a printing method in which dyes are sublimated into vapor phase condensation on the surface of polyester and other fabrics through high temperature (about 200°C), and then penetrate into the amorphous region of fiber macromolecules, and are fixed inside the fiber after cooling. Dispersed printing patterns have the characteristics of lifelike, detailed colors, clear layers, firm color fastness, and strong three-dimensional effect. [0003] The Chinese invention patent with the publication number CN106958157A discloses a process for imitating dispersion printing of polyester fabrics. The steps include: gray fabric pretreatment, preparation of flower paste, paint dispersi...
