Water-based dye sublimation ink and preparation method thereof

Abstract

The invention discloses water-based dye sublimation ink and a preparation method thereof. The water-based dye sublimation ink is prepared from the following components in percentage by weight: 18 to 50 percent of dye dispersion liquid, 0.5 to 5 percent of a second dispersing agent, 20 to 30 percent of a second humectant, 0.5 to 2 percent of a surfactant, 0.05 to 0.2 percent of a second sterilizingagent, and 25 to 45 percent of deionized water. When the water-based dye sublimation ink is prepared, the second humectant, the second sterilizing agent, the surfactant and the deionized water are mixed and stirred to be uniform at normal temperature, so that mixed liquor is obtained; the dye dispersion liquid is added to the mixed liquor, and low-speed stirring is performed for 0.5 to 2 hours ata 100 to 400 rpm rotating speed, so that an ink semi-finished product is obtained; a sampling test is performed to obtain the physical and chemical parameters of the ink semi-finished product, and the color of the ink semi-finished product is adjusted till the color meets an acceptance standard. The water-based dye sublimation ink is high in concentration, and outputs an excellent color effect ina condition of an extremely small amount of jet ink.

Description

technical field [0001] The invention relates to the field of digital inkjet printing, and specifically discloses a water-based thermal sublimation ink and a preparation method thereof. Background technique [0002] With its small batch, short process and fast delivery, digital inkjet printing technology can satisfy consumers' personalized, diversified and fast fashion digital printing field. Inkjet printing ink is the key in inkjet printing technology. Water-based sublimation ink for digital printing is favored by many consumers because of its low odor and low volatility, which makes it environmentally friendly. [0003] Polyester fiber is one of the most important textile fiber varieties in the world. Disperse dyes can be sublimated into the polyester fiber molecules to color the fabric without affecting the feel of the fabric. At the same time, the position of disperse dyes in inkjet printing of polyester fabrics is very prominent, and the preparation of water-based inks...

[0005] Thermal transfer ink can also be called sublimation ink, which is used for heating transfer printing products. The sublimation ink is bright in color, and the pattern printed on the paper is light and clear. After heating and transferring through the thermal transfer machine, the image is clear and the color The degree of reduction is high, and most of the manufacturers of thermal transfer inks in my country are currently concentrated in southern cities, but the color of domestic thermal transfer inks is relatively light. For low-weight thermal transfer papers, the color transfer rate is low. The transfer paper is prone to wrinkles and scratches the print head, resulting in core parts (high loss of print head)
