Problems solved by technology

[0004] However, since the main raw material for preparing sodium alginate is kelp, not only the resources are limited, but also the cost is high. The price of each ton of sodium alginate dry powder is about 40,000 yuan, and each ton of dry powder can be prepared with 10 tons of printing paste, which is used in the printing and dyeing industry. The cost per ton of color paste is about 4,000 yuan, and the production cost is very high
In addition, the stability period of sodium alginate slurry is too short when used, and the slurry can only be stored for 2 days at room temperature. It needs to be printed and used immediately under high temperature in summer, which is inconvenient and easy to cause waste

Abstract

The invention relates to the technical field of textile printing and dying, in particular to a composite printing paste and a preparation method thereof. The raw material of the composite printing paste comprises the following components in percentage by weight: 1.45-1.55 percent of modified carboxymethylcellulose, 0.45-0.65 percent of dying resistant salt, 0.1-0.2 percent of sodium hexametaphosphate, 4-5 percent of sodium bicarbonate, 8-9 percent of urea, 5-6 percent of 909 thickening agent and the balance of water. The water is added at normal temperature to be uniformly stirred for later use. When used as active dye printing paste, the invention has high tinctorial yield, saves dye and is excellent novel composite printing paste.

Description

technical field [0001] The invention relates to the technical field of textile printing and dyeing, in particular to a composite printing paste and a preparation method thereof. Background technique [0002] Printing paste refers to the substance added to the printing paste to thicken. Generally, it can be dissolved in water or fully swelled and dispersed in water to form a thick colloidal solution. When preparing printing paste, part of the dye is dissolved in water, and another part of the dye is dissolved, adsorbed or dispersed in the printing paste, that is, the paste acts as a carrier for the paste. Whether the physical and chemical properties of the paste used to prepare the color paste are appropriate will directly affect the printing quality of the printed product, such as the vividness of the color, the clarity and penetration of the pattern outline, and the technical indicators such as the ease of washing after printing. Therefore, printing paste occupies an impor...
