Abstract

The embodiment of the invention discloses textile dispersed direct-injected ink. The ink is prepared from the following raw materials in percentage by mass: 15 to 50 percent of direct-injected dispersed dye color paste, 5 to 10 percent of a cosolvent, 24 to 27 percent of a humectant, 0.9 to 2 percent of a high molecular surfactant, 0.1 to 0.2 percent of a defoamer, 1 to 2 percent of a dispersing agent, 0.1 to 0.2 percent of a corrosion remover, 0.1 to 0.2 percent of a pH buffer solution, and the balance of water. The application process of the dispersed direct-injected ink in an inkjet printing technology is as follows: printing the dispersed direct-injected ink to the surface of fiber fabric through an inkjet printing method, and performing baking, so as to obtain printed fiber fabric. The dispersed direct-injected ink can improve the performance, such as color fastness and environmental protection performance, not only improves the washing fastness and rubbing fastness of the dispersed dye and has a wide application range, but also shortens the inkjet printing process, and avoids discharge of sewage during pretreatment.

Description

technical field [0001] The embodiment of the invention relates to the technical field of textiles, in particular to a textile direct-injection disperse dye color paste and a preparation method thereof. Background technique [0002] Direct-injection digital printing technology is a new type of green environmental protection printing technology. Compared with the traditional printing technology, the printed pattern is directly printed on the fiber by the printer, and then steamed to fix the color, which reduces the process of plate making and printing, effectively controls the production cost and time, and reduces environmental pollution and other problems. It greatly improves the printing accuracy and meets the needs of small quantity and personalized printing. But at the same time, some application properties of dyestuffs, such as: the vividness of dyed textiles, rubbing fastness, light fastness, washing fastness, sublimation fastness, etc., are more and more paid attention...
