Abstract

The invention discloses high-temperature direct-injection dispersion ink and a preparation method thereof. The high-temperature direct-injection dispersion ink comprises the following components in parts by mass: 10-60 parts of a high-temperature dispersion dye, 10-60 parts of an organic solvent, 10-70 parts of water, 0.5-5 parts of a surfactant, 0.1-0.5 part of a fungicide, 0.1-2 parts of a pH value adjusting agent and 0.1-10 parts of a softening agent. The high-temperature direct-injection dispersion ink disclosed by the invention is relatively good in comprehensive property, not only relatively high in sun-curing fastness, washing resistance, acid-base resistance and sublimation fastness, but also simple and convenient in preparation process, relatively low in cost, free of transfer printing of thermal transfer printing paper, greatly low in production cost and free of secondary pollution, has the characteristic of green and environment-friendly production since only a trace amount of water is needed in a sizing process, can be applied to industrial digital printing machines, is simple and rapid in printing process and can be efficiently produced.

Description

technical field [0001] The invention belongs to the field of textile dyes, and in particular relates to a high-temperature direct-injection dispersion ink and a preparation method thereof. Background technique [0002] my country is a big country in traditional textile printing and dyeing. However, the traditional printing method produces a large amount of printing and dyeing wastewater every year, which is one of the important sources of water pollution in my country. This extensive economy that trades resources for economy has seriously hindered my country's sustainable development. [0003] At present, the thermal transfer digital printing technology widely used in the market mainly has the following defects: (1) Thermal transfer printing needs to consume a large amount of special paper for thermal transfer printing, and the papermaking process and the recycling of waste paper, Both will consume a large amount of water resources, causing secondary pollution, which poses a ...
