Embodiment 1

[0016] First, measure deionized water into the grinder, then add 1% Tween 80, 1% nonylphenol ethoxylate, 1% sodium lignosulfonate, 0.5% polyacrylamide and 1 % acetic acid and other auxiliary agents, finally add 5% commercial disperse dyes, control the grinding speed at 5000 rpm, and grind for 5 hours. After testing, the particle size range of the disperse dye is 100-300nm, and then the material can be discharged. This nano-color paste is used for printing and dyeing operations, and the wet and dry friction resistance of gray fabrics are tested to meet the industry requirements (see attached table).

Embodiment 2

[0018] First, add metered deionized water into the grinder, then add 1% Tween 80, 3% nonylphenol polyoxyethylene ether, 2% tannin polyacrylate, 1% polyacrylamide and Various additives such as 3% acetic acid, and finally add 10% commercial disperse dyes, control the grinding speed at 10,000 rpm, and grind for 3 hours. After testing, the particle size range of the disperse dye is 100-300nm, and then the material can be discharged. This nano-color paste is used for printing and dyeing operations, and the wet and dry friction resistance of gray fabrics are tested to meet the industry requirements (see attached table).

Abstract

The invention discloses a nano disperse dye color paste suitable for polyester printing and dyeing and a preparation method thereof. The nano disperse dye color paste is specifically prepared from, bymass, 5-25 parts of a commercial disperse dye, 2-5 parts ofa surfactant, 1-5 parts of a polymer dispersant, 0.5-2 parts of a protective colloid, 0.5-5 parts of an acid-base regulator and the balancedeionized water. The preparation method comprises the following steps: firstly, adding the metered deionized water into a grinder, then adding auxiliaries in sequence, finally adding the commercial disperse dye, controlling the grinding speed to 5000-10000 rpm, and executing grinding for 3-5 hours. By testing the particle size distribution of the disperse dye, if it is at 100-300 nm, it is indicated that the disperse dye meets the requirements of color paste indexes. The disperse dye paste has the nanoscale dye particle size, is high in stability, is easily adsorbed and penetrates into grey cloth, can reduce surface dyeing and significantly improves the color fastness on the grey cloth.

Description

technical field [0001] The invention belongs to the field of preparation of printing and dyeing paste, in particular to a preparation technology of nanometer disperse dye paste and its application in the printing and dyeing industry. Background technique [0002] Disperse dyes are a kind of non-ionic dyes with relatively simple structure, slightly soluble in water, and exist in the dispersion of fine particles in the solution. The molecular structure of the dye does not have -SO 3 - 、-COO - and other water-soluble groups, but only have a certain number of -OH, -NH 2 and other non-ionic polar substituents, so their solubility in water is very low. In addition, the solubility of disperse dyes in water is also related to its particle diameter. Therefore, a large amount of dispersant needs to be added during the commercial processing of disperse dyes. When dyeing, disperse dyes are dispersed in water with the help of dispersants in the form of a suspension, which improves t...
