Problems solved by technology

[0004] Conventional polyester fabric printing generally uses high-concentration sodium alginate paste. In the printing process, there are printing pastes that are difficult to wash, use a large amount, high COD in wastewater, low color fixation rate of disperse dyes, poor color fastness, serious color sticking, Efficient soaping, long process, etc.

Abstract

The invention relates to printing gum for polyester fabrics and a novel low-gum printing method. The novel low-gum printing method is realized by the aid of a combination synergia effect of a printing gum composition for the polyester fabrics. The printing gum composition is used for replacing high-concentration sodium alga acid gum for printing polyester fabrics, and problems that the conventional printing gum is difficult to clean, utilization quantity is high, wastewater COD (chemical oxygen demand) is high, disperse dye fixation degree is low, dyeing fastness is poor, color mixing is severe, efficient soaping process flow is long, and the like are resolved. By the aid of the printing gum composition for the polyester fabrics and the novel low-gum printing method, the process flow of a printing processing procedure of fabrics is reasonable, the quantity of wastewater is reduced, a production process is clean and environment-friendly, the quality of products is table, and dye color yield is high.

Description

technical field [0001] The invention relates to a polyester fabric printing technology, in particular to a polyester fabric printing paste composition and a new low-paste printing method. Background technique [0002] In the past ten years, the problems of energy shortage and environmental pollution have become increasingly prominent. At the same time, the competition in the international textile market has become more intense, requiring high processing efficiency and low processing costs. There are certain expansions in fabrics, dyes, processes and even auxiliaries. [0003] Polyester fabric has the characteristics of high strength, high elasticity and high wear resistance, and is widely used in industry, civil and national defense. Disperse printing products are bright in color, soft to the touch, and high-grade. Their wear resistance and light weight are higher than those of ordinary pure cotton clothing fabrics. [0004] Conventional polyester fabric printing generally...
