Abstract

The invention provides environment-friendly printing gum. The environment-friendly printing gum is mainly prepared from sesbania powder, Chinese honey locust extract, chondrus crispus, gelatin, sodium ethoxide and water, sodium ethoxide is organic alkali, the others are natural extracts, sodium ethoxide is pharmaceutic-grade raw material and harmless to the human body, and therefore the gum is environmentally friendly and healthy; chondrus crispus is selected as the main raw material, the sesbania powder, the Chinese honey locust extract and a small amount of gelatin are added, the printing gum has an excellent dyeing assisting effect on textile of natural fiber such as cotton and hemp, is high in compatibility with natural printing dye, high in paste forming rate and permeability and bright in color and particularly has an excellent improving effect on dyeing chromatic aberration of blended textile; in the preparing process, the temperature of a water bath is controlled, the water bath time is correspondingly prolonged, but the part of organic component in chondrus crispus is protected, and by combining the Chinese honey locust extract, the printing gum has certain antibiosis and bacteriostat effects on dyed fibers.

Description

technical field [0001] The invention relates to the field of printing and dyeing auxiliaries, in particular to an environment-friendly printing paste and a preparation method thereof. Background technique [0002] Printing paste refers to a polymer compound that can thicken the printing paste. [0003] Before the printing paste is added to the printing paste, it is generally a thick colloidal solution of hydrophilic polymer that is soluble in water or fully swollen and dispersed 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. The composition of the printing paste is the main component of the printing paste, which determines the printing performance, the surface color of the dye, the smoothness of the pattern outline, etc. [0004] The role of printing paste in the printing process has four aspects: ...
