2. Hand feeling of printed fabrics: After heat transfer printing at a high temperature above 200°C, fabrics tend to feel hard after printing, especially for velvet and wrinkle fabrics. After printing, the velvet and wrinkle feel will decrease or even disappear completely. , affecting the quality of printed products
It can be seen that although high-temperature disperse inks have performance advantages in inkjet printing, there are still deficiencies in the inks produced by the prior art: 1. Storage stability: because disperse dye inks use water as a solvent, disperse dyes are insoluble in water , the prior art usually uses a dispersant to evenly disperse the dye in water. The ink is composed of disperse dyes, water, surfactants and polyols in tiny particles, but since the dye particles may Flocculation and precipitation lead to large particles and wide particle size distribution of disperse dye inks, resulting in poor storage stability of disperse dye inks, which restricts its wide application in the field of textile printing and dyeing
2. Stability during jetting: due to the unsatisfactory stability during storage, resulting in large ink particles clogging the nozzle during inkjet printing, etc., the stability during jetting is often unsatisfactory
3. High cost: In order to maintain the small particle size of the dye after grinding, it is necessary to add a variety of large amounts of dispersants, which will inevitably increase the production cost of the ink, increase the burden on the enterprise, and reduce its market competitiveness

Abstract

The invention relates to the field of digital ink-jet printing ink, in particular to high-temperature direct-injection disperse dye ink as well as a preparation method and application thereof. The high-temperature direct-injection disperse dye ink comprises the following components in percentage by weight of 3-15% of a high-temperature disperse dye, 1-15% of a self-made dispersing agent, 30-60% of an organic solvent, 0.5-2% of a surfactant, 0.05-0.2% of a bactericide, 0.1-0.5% of a defoaming agent and the balance of deionized water. The high-temperature disperse direct-injection ink only needs to be added with the self-made dispersing agent, has extremely excellent stability, avoids adverse effects on compatibility of an ink system due to addition of multiple and numerous dispersing agents, reduces product cost, and provides a better selection scheme for digital textile disperse dye printing.

Description

technical field [0001] The invention relates to the field of digital ink-jet printing inks, in particular to a high-temperature direct-injection disperse dye ink and a preparation method and application thereof. Background technique [0002] In addition to being used in desktop printing, inkjet printing has also developed rapidly in printing applications on textiles in recent years. Digital inkjet printing is to pass the pattern through the scanner, convert the design pattern into digital form, input it to the computer, edit and process it through the computer printing color separation and drafting system, and then the computer controls the micro piezoelectric inkjet nozzle to directly spray the special ink to the computer. On textiles, the color is mixed and restored to the original scanning pattern. Compared with the traditional printing method, it has the advantages of flexible design, fast speed, low energy consumption, no pollution, material saving, and high product qua...
