Example Embodiment

[0023] Example 1

[0024] A water-based disperse dye ink for polyester textile inkjet printing, which is composed of the following components according to mass percentage: disperse dye CI disperse red 14.5%; 1-butyl-3-methylimidazole chloride salt ionic liquid 0.5%; surface tension Adjusting agent ethylene oxide and ethylene glycol adduct 1%; viscosity adjusting agent pentanediol 1%; sodium hydroxide pH adjusting agent 0.2%; the rest is deionized water. After mixing the above-mentioned components uniformly in proportions and then mechanically stirring them to form a transparent and uniform solution, the water-based disperse dye ink for inkjet printing can be prepared, which is still clear and transparent after standing at room temperature for 7 days.

Example Embodiment

[0025] Example 2

[0026] A water-based disperse dye ink for polyester textile inkjet printing, which is composed of the following components according to mass percentage: disperse dye CI Disperse Blue 12.2%; 1-ethylpyridine hydrochloride ionic liquid 0.1%; surface tension regulator epoxy The adduct of ethane and ethylene glycol 1%; the viscosity regulator triethylene glycol 1%; the sodium hydroxide pH regulator 0.2%; the rest is deionized water. After mixing the above components uniformly in proportion and mechanically stirring to form a transparent and uniform solution, water-based disperse dye ink for inkjet printing can be prepared. It remains clear and transparent after 4 days at room temperature without flocculation or precipitation. .

Example Embodiment

[0027] Example 3

[0028] A water-based disperse dye ink for polyester textile inkjet printing, which is composed of the following components according to mass percentage: disperse dye CI disperse yellow 9.3%; benzimidazole tetrafluoroborate ionic liquid 0.15%; surface tension regulator epoxy The adduct of ethane and ethylene glycol 1%; the viscosity regulator tetraethylene glycol 1%; the sodium hydroxide pH regulator 0.2%; the rest is deionized water. After mixing the above components uniformly according to the proportions and mechanically stirring them to form a transparent and uniform solution, the water-based disperse dye ink for inkjet printing can be prepared. It will still have high transparency after 3 days at room temperature without flocculation. Or the appearance of precipitation.

Abstract

The invention relates to water-based dispersion liquid dye ink for ink jetting and printing of a polyester textile. The ink comprises the following components by mass percent: 0.5-15% of dispersion dye, 0.05-5% of ionic liquid, 0.1-3% of surface tension modifier, 0.1-3% of viscosity modifier, 0.2-2% of pH modifier and the balance of deionized water. During ink preparation, auxiliary agents such as other dispersion agents and a surfactant are not required; solvent composition for preparing a co-dispersion dye is very simple, and only the ionic liquid is required in principle. The ink is simple in method and convenient to operate, and grinding in a grinding mill, nanofiltration and the like do not exist, so that the ink is green, pollution-free and environment-friendly, and has no harm to working personnel.

Description

technical field [0001] The invention belongs to the field of dispersion liquid dye ink, in particular to an aqueous dispersion liquid dye ink for inkjet printing of polyester textiles. Background technique [0002] Disperse dyes are mainly used for dyeing (printing) of polyester and its textiles, and can be used for dyeing (printing) of acetate fiber and nylon fiber textiles, and can also be used for transfer printing. At present, disperse dyes have a wide variety of chromatograms, excellent performance, and wide application, and have become the fastest-growing category of various dyes. [0003] With the rapid development of computer technology in the field of textiles. In recent years, people have applied paper inkjet printing technology to textile printing, clothing and so on. Inkjet printing has the advantages of short process, small batch, fast delivery, etc. Therefore, it has attracted widespread attention from people in the printing and dyeing industry. Especially w...
