Reactive printing paste and production method thereof

Abstract

The invention relates to the technical field of production methods and particularly relates to reactive printing paste and a production method thereof. The reactive printing paste comprises the following raw materials in percentage by mass: 15-60% of alginate, 35-80% of refined printing paste, 0.5-5% of an alcohol wetting agent and 0.3-2% of a preservative. According to the reactive printing paste, the raw material is less in consumption and low in cost, and the reactive printing paste is resistant to electrolyte and biodegradation, capable of increasing the color yield by 30% and greatly reducing the dye used later, beneficial to the reduction of three wastes and low in production and use costs. The preparation method of the reactive printing paste provided by the invention is simple in process, convenient to operate and beneficial to the scaled production.

Description

technical field [0001] The invention relates to the technical field of development methods, in particular to an active printing paste and a development method thereof. Background technique [0002] In the prior art, printing paste is a high molecular compound that acts as a thickener in printing paste, which can be dissolved in water or fully swelled and dispersed in water to form a thick colloidal solution. As the main component of printing paste, it determines to a large extent the shade of printed fabrics, the amount of color on the surface, the clarity of pattern outlines, the uniformity of printing, and the feel of fabrics. It is an important factor affecting the printing effect. factor. The traditional printing thickener is sodium alginate, but sodium alginate is not resistant to strong acid, strong alkali and heavy metal ions; it is easy to mildew and has poor storage stability; the structural viscosity of the original paste is low, which is not conducive to high-mes...

AI Technical Summary

Problems solved by technology

The traditional printing thickener is sodium alginate, but sodium alginate is not resistant to strong acid, strong alkali and heavy metal ions; it is easy to mildew and has poor storage stability; the structural viscosity of the original paste is low, which is not conducive to high-mesh screen printing; For flat screen printing, the fluidity is relatively large, and there are defects such as permeability, screen penetration, color yield, and vividness, etc., so its application is subject to certain restrictions.

[0003] In addition, sodium alginate is mainly extracted from kelp (natural seaweed), but with the application of sodium alginate in the food industry and pharmaceutical industry this year, seaweed resources are very tight, and the cost has increased significantly; in addition, sodium alginate slurry is being used The stable period is too short, and the storage period at room temperature is only 2 days. It needs to be printed and used immediately under high temperature in summer, and it is not resistant to biodegradation.

In addition, in the prior art, imported synthetic thickeners are also used to replace sodium alginate, but the imported thickeners are more polluted, the cost of imported raw materials is higher, they are not resistant to electrolytes, they are easy to stain, and the desizing is not thorough, resulting in Low color, large amount
