Abstract

The invention discloses digital inkjet thermal transfer printing water-based ink for textiles and preparation method of the ink. The ink comprises the following raw materials in mass ratio: 5-15 parts of disperse dye, 5-10 parts of a dispersing agent, 0.1-0.5 part of a wetting agent, 5-25 parts of a cosolvent, 0.02-0.05 part of a preservative, 0.1-0.3 part of an antifoaming agent and 50-70 parts of deionized water. The digital inkjet thermal transfer printing water-based ink is prepared by using a method of effectively dispersing the disperse dye via a dispersing system and carrying out combined dispersion via a mechanical sand grinder and an ultrahigh-pressure homogenizer, and is suitable for the thermal transfer printing of textiles and the thermal transfer printing of plate materials such as aluminum plates coated with polyester; and the prepared water-based ink has the advantages of small particle size, uniformity in distribution, good stability, no nozzle blocking, rapidness in drying, bright color, clear patterns, high transfer rate, low cost and the like.

Description

(1) Technical field [0001] The invention relates to textile thermal transfer printing ink and its preparation, in particular to a water-based ink applied to digital inkjet thermal transfer printing and a preparation method thereof. (2) Background technology [0002] Thermal transfer printing is to print the required pattern on the special paper by printing the disperse dye first, and make the transfer printing paper, and then use the thermal sublimation effect of the disperse dye to heat the pattern on the paper in the temperature range of 200-220℃. A printing method in which patterns are transferred to textiles. There is no environmental pollution problem in heat transfer printing, which is in line with the national policy of energy saving and emission reduction, and is a convenient and efficient environmental protection printing process. [0003] The goal of textile digital inkjet heat transfer printing is to replace traditional heat transfer technology. Due to the combi...
