Problems solved by technology

[0006] As the main consumables for inkjet printing of synthetic fiber fabrics, disperse dye ink must have appropriate viscosity (2-10mPa s), surface tension (30-50mN / m), pH value (7-9) and sufficient stability, etc. Performance index requirements, to ensure good jet printing performance; the existing disperse dye ink is mainly composed of disperse dyes, water, surfactants and polyols that exist in tiny particles, but due to the disperse dyes in the existing disperse dye inks Poor dispersion stability leads to large particles of disperse dye inks, wide particle size distribution, easy to block nozzles and other defects during use, and the storage stability of disperse dye inks is not good, which restricts its wide application in the field of textile printing and dyeing

Abstract

The invention provides disperse dye ink with good storage stability and good redispersibility and a preparation method. The disperse dye ink is prepared from components in parts by mass as follows: 30-35 parts of high-purity water, 10-15 parts of disperse dye, 8-12 parts of a dispersant, 5-9 parts of a lubricant, 6-8 parts of ethylene glycol and 1-5 parts of an anionic surfactant. The disperse dyeink has good dispersion stability, excellent storage stability and excellent redispersibility.

Description

technical field [0001] The invention relates to the technical field of ink, in particular to a disperse dye ink with good storage stability and redispersibility and a preparation method. Background technique [0002] Digital inkjet printing is to pass the pattern through the scanner, convert the cloth sample (design pattern) into digital form and input it to the computer, edit and process it through the computer printing color separation and drafting system, and then the computer controls the micro piezoelectric inkjet nozzle to print the special The dye solution (collectively referred to as ink) is directly sprayed onto the textile, and the color is mixed and restored to the original scanning pattern. Compared with the traditional printing method, it has the advantages of flexible design, fast speed, low energy consumption, no pollution, saving materials, and high product quality. It not only relieves the burden of the enterprise, but also realizes the requirements of envir...
