Abstract

The invention relates to the technical field of preparation of vapor deposition materials, in particular to high-performance reactive printing paste. The high-performance reactive printing paste comprises the following components in percentages by weight: 2-5% of composite paste, 2-5% of an aqueous thickener, 3-7% of an alkaline agent, 0.1-1% of a leveling agent, 0.5-3% of a dye inhibitor, 10-15%of urea and the balance of water. The composite paste and the aqueous thickener are used in combination, so that the color yield is higher than that of traditional sodium alginate, and the color is bright; and in addition, the printing paste prepared by the method disclosed by the invention not only can improve the screen permeability of printing, but also can improve the stability of reactive dyes, uniform coloring is ensured, the reproducibility is good, and a printed fabric is tidy, soft and comfortable in surface, and meets demands of the public.

Description

technical field [0001] The invention belongs to the technical field of textile chemistry, and more specifically, the invention relates to a high-performance active printing paste. Background technique [0002] In the process of textile printing, paste is one of the most important components of printing paste. Its functions include preventing bleeding and making the pattern outline clear; as a carrier to transfer dyes and auxiliaries to fibers; Agent medium; as a protective colloid, to prevent the reaction between additives and so on. [0003] At present, commonly used printing pastes are mainly organic polymer compounds, including natural pastes, such as starch, vegetable glue, seaweed, etc., and synthetic pastes, such as vinyl derivatives, polyacrylic acid derivatives, synthetic rubber, etc. Among them, sodium alginate and natural plants are traditional paste raw materials. Because of their high price and few raw materials, various synthetic pastes have been developed in r...
