Problems solved by technology

[0004] The technical problem to be solved by the present invention: in view of the poor penetration effect of the existing printing paste, which reduces its paste rate, affects the quality of the fabric, and causes its poor hand feeling, the present invention first uses hydrogen peroxide to oxidize corn starch treatment, followed by aloe vera gel to adjust the viscosity, modified by microorganisms, supplemented with ammonium carbonate to increase its permeability, then added 3-chloro-2-hydroxypropyltrimethylammonium chloride for etherification treatment, and finally mixed with cinnamon acid to react to prepare printing paste, the printing paste prepared by the present invention has good permeability, improves its paste rate, and makes the fabric feel soft after use

Abstract

The invention relates to a method for preparing printing paste from corn starch, and belongs to the technical field of printing paste preparation. The method comprises the steps that oxidation treatment is firstly conducted on the corn starch through hydrogen peroxide, the viscosity is regulated with aloe gel, modification is conducted through microorganisms, the permeability of the corn starch is improved through assistance of ammonium carbonate, and then 3-chloro-2-hydroxypropyltrimethylammonium chloride is added for etherification treatment; finally, the corn starch reacts with cinnamic acid, and then the printing paste is prepared. According to the printing paste prepared through the method, the permeability is high and reaches 35% or above, the paste forming effect is improved, and the paste forming rate reaches 7.8%-13.5%; after the printing paste is used, a fabric is uniform in obtained color, high in color fastness and soft and smooth in handfeel.

Description

technical field [0001] The invention relates to a method for preparing printing paste based on cornstarch, and belongs to the technical field of printing paste preparation. Background technique [0002] Printing paste refers to a polymer compound that can thicken the printing paste. Before the printing paste is added to the printing paste, it is generally soluble in water, or a hydrophilic polymer thick colloid solution that can fully swell and disperse in water, or an oil / water type or water / oil type emulsified paste . When preparing printing paste, part of the dye is dissolved in water, and the other part is dissolved, adsorbed or dispersed in the original printing paste. Printing paste is the main component of printing paste. As the carrier and medium of dyes and auxiliaries in the printing process, it determines the running performance of printing, the amount of color given by dyes, the smoothness and clarity of pattern outlines, etc. In short, the quality of printing...
