Problems solved by technology

However, because the carboxyl group in sodium carboxymethyl starch is easy to combine with the active group in reactive dyes, it causes problems such as poor fastness, light color, easy to bleed when exposed to water, and rubbing and fading.

Abstract

The invention relates to sodium alga acid printing paste, comprising the following components in percent by weight: 60-90% of sodium alga acid, 5-15% of sodium hexametaphosphate and 5-25% of anhydrous sodium sulphate. The preparation method of the sodium alga acid printing paste comprises the following steps of: (1) weighing sodium alga acid, sodium hexametaphosphate and anhydrous sodium sulphate in the proportion of a formula; (2) smashing the sodium alga acid to 30-40 meshes; (3) placing smashed sodium alga acid, sodium hexametaphosphate and anhydrous sodium sulphate into a mixing tank to be stirred; and (4) stirring to be completely uniform, thus the sodium alga acid printing paste finished product is obtained. The sodium alga acid printing paste disclosed by the invention has the beneficial effects that (1) sodium carboxymethyl starch having adverse effects on colouring is removed, and anhydrous sodium sulphate which can activate active groups in dye and has high colouring rate is adopted; and (2) sodium hexametaphosphate can cause calcium ions or magnesium ions in water to enter into sodium hexametaphosphate molecules to be changed into stable soluble complex, thus permeability of the printing paste is improved, colour fastness is improved, and the dye can be saved.

Description

technical field [0001] The invention belongs to a carrier for fabric printing and dyeing, in particular to a sodium alginate printing paste for printing and a preparation process thereof. Background technique [0002] Sodium alginate paste is an ideal paste in printing applications. Its biggest feature is that it does not react with dyes, and it is easy to transfer dyes from paste to fibers. The printed pattern is clear and the color yield is high. Feel good. Sodium alginate pulp is not only suitable for printing on cotton cloth, but also suitable for printing on wool, silk and synthetic fibers. [0003] Most of the current sodium alginate pulp is made of pure sodium alginate, which is mainly extracted from kelp, but in recent years, with the application of sodium alginate in the food industry and pharmaceutical industry, seaweed resources are becoming more and more scarce. The cost is obviously increased; in addition, the stability period of sodium alginate slurry is too ...
