Fluorescent disperse dye ink for inkjet printing and preparation method of fluorescent disperse dye ink

Abstract

The invention discloses fluorescent disperse dye ink for inkjet printing and a preparation method of the fluorescent disperse dye ink. The ink consists of a disperse dye, a fluorescent agent, a versatile dispersant, an organic solvent, a wetting agent and a surfactant. The preparation method comprises the following steps: stirring the disperse dye, the fluorescent agent, sodium lignin sulfonate, diethylene glycol and deionized water at a low speed by using a stirrer, and grinding in a grinding dispersion mill, thus obtaining disperse dye mill base with a solid content of 15 percent; stirring the dye mill base and the deionized water in the stirrer, adding an organic solvent formed by mixing isopropanol, thiodiglycol and biglycol ether and the wetting agent and the surfactant, and adding a preservative after the PH value is regulated to be 8-9; and filtering the mixed ink by using a millipore filter membrane, and further filtering the filtrate through the millipore filter membrane. The fluorescent disperse dye ink can be subjected to jet printing onto heat transfer paper from a piezoelectric inkjet printing machine, or is directly subjected to jet printing onto a chemical and blended fabric, and is suitable for large-scale industrial production.

Description

technical field [0001] The invention relates to a fluorescent disperse dye ink used for inkjet printing and a preparation method thereof, belonging to the fields of organic chemistry and textile printing and dyeing. Background technique [0002] Existing disperse dye inks are complicated to manufacture and require a large investment, and are not suitable for large-scale industrial production. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a fluorescent disperse dye ink for inkjet printing and a preparation method thereof. The fluorescent disperse dye ink for inkjet printing can be sprayed from a piezoelectric inkjet printing machine to thermal On the transfer paper, or directly on the chemical fiber fabric, after spray printing, it is only necessary to properly bake the fabric and the transfer paper at 210 °C; the preparation method of the fluorescent disperse dye ink for inkjet printing is simple, The method h...
