Abstract

The invention relates to a high-color-yield tamarind seed gum preparation method and belongs to the technical field of fabric printing. For solving the problem that an existing prepared high-color-yield tamarind seed gum has slightly poor water solubility, stability, water retention and other properties, accordingly printing color yield is low when the tamarind seed gum serves as a paste material, and the demand of existing fabric printing cannot be met, microbial modification is conducted on carboxymethyl tamarind seed gum by conducting carboxymethyl modification on the tamarind seed gum and meanwhile screening oil flooding bacteria, a hydrophilic group is grafted. The prepared high-color-yield tamarind seed gum by adopting the preparation method is good in water retention property and has high structural viscosity, the printing viscosity index is effectively improved, the color yield can be improved by 1-2 times, preparation steps are simple, and the high-color-yield tamarind seed gum is green, safe and pollution-free.

Description

technical field [0001] The invention relates to a method for preparing tamarind gum with high color yield, and belongs to the technical field of fabric printing. Background technique [0002] The effect of fabric printing depends largely on the color thickener, that is, the nature of the paste. Printing paste is a kind of polymer compound that acts as a thickener in the printing color mass. It can be dissolved in water or can be fully expanded, swollen and dispersed in water to form a thick concentrated solution or colloidal solution. As the main component of printing color clothing, it determines to a large extent the shade of the printed fabric, the amount of color on the surface, the clarity of the outline of the pattern, the uniformity of printing, and the feel of the fabric, etc. ⑴, it is an important factor affecting the printing effect. factor. In our country, although the production and application of printing paste have a long history and a certain foundation, the...
