Problems solved by technology

The applicant has carried out a large number of application tests on various natural polymer pastes and synthetic pastes, and found that most of them are prone to cause reactive dyes and The printing paste undergoes cross-linking reaction, which reduces the color yield and makes the hand feel hard, which is not suitable
In addition, synthetic pastes generally have the problems of poor electrolyte resistance and hard fabric printing, which greatly restricts the application

Abstract

The invention relates to a paste applied during the printing process of active dyes of textiles and the preparation method thereof. The method comprises the steps as follows: subjecting wood pulp to acidification treatment, alkalization treatment, etherealization treatment and carboxylation treatment to obtain a component (A); subjecting potato starch to alkalization, cross-linking and grafting treatment, introducing sulfoethyl group, conducting etherealization treatment to obtain a component (B); taking kollidon as a component (C); and mixing the components (A), (B) and (C) at a ratio of 5:4:1. The paste as a novel printing paste can improve the printing performance, reduce the production cost and replace sodium alginate.

Description

technical field [0001] The invention relates to a paste used in the printing process of textile reactive dyes. Background technique [0002] The process of textile reactive dye printing requires the use of paste as a carrier to transfer reactive dyes and auxiliaries to textile fibers. Since the advent of reactive dyes for more than 50 years, sodium alginate has been used in the printing and dyeing industry as a commonly used paste for reactive dye printing. Sodium alginate has the excellent properties of brightly printed textile patterns, clear line outlines, good plasticity and permeability, but a large amount of -COO- in sodium alginate molecules has a strong hydration effect, resulting in higher Newtonian viscosity and fluidity. Transgender is not ideal. [0003] In recent years, due to the discovery of the physiological activity of sodium alginate and its application in the food industry, its price has continued to rise, which has greatly increased the production cost ...
