Abstract

The invention relates to a thermal sublimation digital printing ink-jet ink and a preparation method thereof; the weight percentages of ink components are: (1) disperse dye: 1 to 10 percent; (2) dispersant: 1 to 10 percent; (3) organic solvent: 60 to 90 percent; (4) surfactant: 1 to 5 percent; (5) wetting agent: 1 to 5 percent; (6) defoamer: 1 to 5 percent. The preparation method comprises: (1) the disperse dye, the dispersant, the organic solvent, the wetting agent and the deformer are mixed at normal temperature, and a mixed solution can be obtained by stirring the mixture for 0.5 to 1 hour; (2) the mixed solution is homogenized for 0.5 to 5 hours under a high pressure homogenizer, and the stable-dispersed ink, the average particle size of the dispersed dye of which is 100 to 300 nanometers can be obtained; (3) the ink of magenta (M), cyan (C), yellow (Y), black (K), light cyan (Lc) or light magenta (Lm) can be obtained after the ink is filtered by a 2 microns filtering film and a 0.45 micron filtering film. The particle size of the thermal sublimation digital printing ink-jet ink of the invention is even in distribution and good in disperse stability and can be applied on the large scale piezoelectric type digital printing machines of the nozzles of XAAR and SPECTRA, etc and printed on polyester fabrics; ink jetting is smooth without blocking the nozzles; the thermal sublimation digital printing ink-jet ink can be stored for a long time; the patterns printed by the ink of the invention is colorful in color and the thermal sublimation digital printing ink-jet ink is good in color fixation rate, washing fastness and solarization fastness, is simple in the operation of the production method and is environment-friendly.

Description

technical field [0001] The invention relates to an inkjet printing ink and its preparation, in particular to a textile digital printing disperse dye inkjet ink and its preparation method. Background technique [0002] In recent years, digital printing technology has become more and more widely used in the world, which is the product of the combination of computer technology and printing and dyeing industry. Due to the different nozzle principles of different types of machines, digital printing and dyeing inks are also selected differently. At present, digital printing and dyeing inks can be divided into water-based, oily and solvent-based according to the main components in the system; according to different colorants, they can be divided into pigments and dyes. There are two categories, and dyes are usually divided into disperse dyes, reactive dyes and acid dyes, among which disperse dyes are especially suitable for dyeing polyester and other fibers. [0003] Digital print...
