Embodiment 1 to Embodiment 4
[0056] According to the components and their dosages listed in the following Table 1, the ionic liquid, alkaline substance, hygroscopic agent and anti-reduction agent were added to the remaining water, and stirred for about 1 hour to obtain the samples of Examples 1 to 4. Composition of pretreatment fluid. In addition, viscosity measurement is carried out with a viscometer (manufactured by Brookfield (BROOKFIELD) company, the equipment name is a microcomputer type viscometer), and the viscosity of the pretreatment liquid composition of Example 1 is about 5 cps, and the pretreatment liquid composition of Example 2 is about 5 cps. The viscosity of the composition is about 5 cps, the viscosity of the pretreatment liquid composition in Example 3 is about 5 cps, and the viscosity of the pretreatment liquid composition in Example 4 is about 5 cps.

Abstract
A pretreatment liquid composition is used for digital printing and includes ionic liquid, alkaline substance, hygroscopic agent, reduction preventing agent and remaining solvent. The content of the ionic liquid is 1 to 5 wt%, the content of the alkaline substance is 1 to 10 wt%, the content of the hygroscopic agent is 1 to 10 wt%, and the content of the reduction preventing agent is 1 to 3 wt%. When the pretreatment liquid composition is applied to digital printing, the digital pattern has good sharpness, and because of its low viscosity, it not only facilitates processing but also reduces washing water consumption when applied to digital printing.
Description
technical field [0001] The invention relates to a pretreatment liquid composition, in particular to a pretreatment liquid composition for digital printing. Background technique [0002] In recent years, the rise of digital digital printing has improved the problems of high pollution and high energy consumption in the traditional textile printing industry. Digital digital printing is a technology that injects patterns into specific positions on cloth or transfer paper with micro-nano ink droplets. Therefore, it is necessary to use a large amount of thickener with a viscosity of about 3000 to 5000 cps during digital pretreatment to Prevent ink from spreading. However, the thickener will be removed through the washing process after the color fixing process, so its high-viscosity characteristics require a large amount of water for washing whether it is a natural or synthetic thickener, and the washed products are likely to cause environmental pollution. pollute.
