Embodiment Construction

[0020] A slurry of this embodiment is used for sizing cloth before inkjet printing, and the slurry is composed of the following components in parts by weight: 63 parts of water, 4-10 parts of urea, 1.3-2 parts of baking soda 0.75 parts of sodium alginate, 1.8 parts of starch, and 0.5-1 part of anti-staining salt. Urea can fully expand the fiber during the color fixing process, create conditions for the reaction of reactive dyes and fibers, and facilitate the ink to fully penetrate into the fabric. Baking soda will affect the coloring rate of the ink in the process of steaming and fixing the color, and play a role in fixing the color. Sodium alginate is a thickener, which can prevent the ink sprayed on the cloth from bleeding during the subsequent steaming and color fixing process, which will affect the fineness of the pattern. Starch is the paste. Sodium alginate cooperates with starch to facilitate ink penetration and improve color fastness. As a weak oxidizing agent, anti...

Abstract

The invention relates to a slurry and a preparation method thereof. Aiming to overcome the disadvantages that in the prior art, when inkjet printing is carried out after cloth sizing, the color is not bright, and the color fastness of ink does not meet the requirement, the invention provides a slurry. The slurry is composed of the following components by weight: 63 parts of water, 4-10 parts of urea, 1.3-2 parts of sodium bicarbonate, 0.75 part of sodium alginate, 1.8 parts of starch, and 0.5-1 part of a reserve salt. The preparation method of the slurry includes the steps of: A. making a mother slurry, specifically at room temperature, by weight part, mixing 43 parts of water, 0.75 part of sodium alginate, 1.8 parts of starch, and 0.5-1 part of the reserve salt for 30min; B. placing the mother slurry at room temperature for 12h; C. at room temperature, further stirring the mother slurry for 1h; D. making a sub-slurry, specifically at room temperature, by weight part, mixing 20 parts of water, 4-10 parts of urea, and 1.3-2 parts of sodium bicarbonate for 20min; and E. mixing the mother slurry and the sub-slurry at room temperature. The slurry provided by the invention maintains the color brightness, improves color fastness, and is suitable for use during cloth sizing before inkjet printing.

Description

technical field [0001] The invention relates to the field of cloth printing, in particular to a slurry used before inkjet printing and a preparation method. Background technique [0002] Compared with traditional screen printing, inkjet printing technology is a brand-new printing method. It abandons the complicated process of plate making in traditional printing, and directly sprays printing on fabrics, which improves the printing accuracy and realizes small batch, Multi-variety and multi-color printing, and solve the problems of traditional printing such as large area and serious pollution. The fabric needs to be sized before inkjet printing, and the ink is sprayed directly onto the sizing-coated fabric. The concentration of each component in the slurry will directly affect the vividness and color fastness of the ink on the cloth. Ink-jet printing after the existing cloth is sized, the color will not be bright and the color fastness of the ink cannot meet the requirements...
