Printing and dyeing ink for direct inkjet textile and preparation method thereof

Abstract

The invention relates to printing and dyeing ink for a direct inkjet textile and a preparation method thereof, the printing and dyeing ink comprises reactive dye, N-methyl-2-pyrrolidone, ethylene glycol monomethyl ether, isopropanol, propanetriol, triethanolamine and deionized water, the printing and dyeing ink for the direct inkjet textile comprises red printing and dyeing ink / yellow printing and dyeing ink / blue printing and dyeing ink / black printing and dyeing ink, and the preparation method of the printing and dyeing ink for the direct inkjet textile is as follows: weighing the reactive dye, the N-methyl-2-pyrrolidone, the ethylene glycol monomethyl ether, the isopropanol, the propanetriol, the triethanolamine and the deionized water respectively, placing in a stirring container, stirring uniformly, then standing, and filtering so as to get a finished product, namely the printing and dyeing ink for the direct inkjet textile. The printing and dyeing ink is excellent in quality, low in price, applicable to different models of inkjet printing machines, abundant and bright in color, strong in stability, strong in coloring power and small in undissolved substances, and can be used for automatically cleaning a spray head, ensuring no blockage and achieving good flowability and smooth jet; and furthermore, wrinkling and diffusion of an image of the direct inkjet textile can be avoided, the color fastness is high, the resistance to ultraviolet radiation is realized, the image can be preserved for 20 years without color fading, and the inkjet printing machine in a shutdown statecan not block the head within half a year.

Description

technical field [0001] The invention relates to a textile printing and dyeing product, in particular to a direct-jetting textile printing and dyeing ink, and also relates to a preparation method of the direct-jetting textile printing and dyeing ink. Background technique [0002] In the prior art, thermal transfer printing technology is generally used to make images on textiles. First, thermal transfer printing technology needs to be spray-painted on paper and then sublimated onto textiles by heating. Such a process produces sublimation but cannot 100% image Sublimation to textiles often causes image distortion; second, thermal transfer cannot be used on cotton fabrics, and the scope of use is limited; third, thermal transfer ink is easy to block the print head of the inkjet printer, which is not conducive to popularization and application; fourth, Inkjet printing machines are expensive and their popularity is not high. Therefore, it is necessary to open up new ways to make ...

Problems solved by technology

[0007] In recent years, although the printing and dyeing ink used in textiles has been disclosed in the literature, it has not been circulated in the market. According to the analysis and research of the inventor's experience in ink for more than 20 years, the printing and dyeing ink used in the above textiles is not yet mature, and there may be such or that kind of problem
