Water-based dispersion liquid dye ink for ink jetting and printing of polyester textile

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...
