Dispersion printing process of polyester sanded cloth

Abstract

The invention discloses a dispersion printing process of a polyester sanded cloth. The dispersion printing process comprises: (1) carrying out desizing-deoiling-whitening first bath; (2) heating a working liquid to 120 DEG C from a room temperature; (3) cooling the working liquid to 80 DEG C from 120 DEG C; (4) carrying out dehydration-width opening-wool scouring; (5) carrying out shaping treatment; (6) carrying out magnetic bar printing, wherein the shaped polyester sanded cloth is subjected to wool suction treatment through a wool suction device in front of a printing machine, the obtained shaped polyester sanded cloth is placed in a slurry containing a synthetic thickener and a dye, and magnetic bar printing is performed; (7) carrying out dry steaming; (8) carrying out water washing, wherein the steamed polyester sanded cloth is subjected to water washing with an environmentally friendly powerful reducing agent; and (9) carrying out shaping drying on the washed polyester sanded cloth. With the dispersion printing process of the present invention, the process steps and the process time are substantially reduced, the production efficiency is improved, and the obtained printed cloth is stable and reliable.

Description

technical field [0001] The invention relates to a printing process, in particular to a dispersive printing process for polyester brushed cloth. Background technique [0002] The existing process of disperse printing on polyester brushed cloth is as follows: gray cloth entering the factory - desizing and degreasing - whitening - dehydration and washing - shaping - absorption of wool - scraper printing - steaming - washing - shaping and drying - finished product. The process slurry uses mixed slurry such as starch, sodium alginate, urea, and PH value regulator. The configuration is complicated and the working fluid is unstable, resulting in hard hand feeling of the fabric; the steaming method is used for steaming, and the steaming time is long. Water-stained printing on the cloth surface; hydrochloric acid is used for washing, which has a strong workshop smell, and the pattern on the white background is easy to be stained and time-shifted; the overall production process is lon...

AI Technical Summary

Problems solved by technology

The process slurry uses mixed slurry such as starch, sodium alginate, urea, and PH value regulator. The configuration is complicated and the working fluid is unstable, resulting in hard hand feeling of the fabric; the steaming method is used for steaming, and the steaming time is long. Water-stained printing on cloth surface; water washing uses hydrosulfite, which has a strong workshop smell, and the pattern on the white background is easy to be stained and time-shifted; the overall production process is long, time-consuming and energy-consuming

Therefore, the existing printing technology has the problems of time-consuming and energy-consuming process, low production efficiency and poor printing quality.
