Embodiment 1

[0048]Digital printing reactive dye inkjet ink, which comprises the following components by weight percentage: reactive black 512%, triethylene glycol 10%, alkoxylated alcohol 0.5%, trimethylolpropenoate 0.8%, EDTA two Sodium 1.8%, thiazole fungicide 0.2%, caprolactam 7%, triethylamine 1%, NP-102%, and the balance is deionized water. The above components are mixed in proportion, stirred for 2 hours and mixed evenly, aged at 60° C. for 24 hours, and filtered with a 0.5-micron medium-speed filter paper to obtain a digital printing active ink.

Embodiment 2

[0050] Digital printing reactive dye inkjet ink, which includes the following components by weight: reactive bright red X-BB 15%, triethylene glycol 12%, alkoxylated alcohol 1%, trimethylolpropenoate 0.8% , EDTA disodium 1.6%, thiazole fungicides 0.2%, caprolactam 10%, triethylamine 1%, NP-10 1.5%, the rest are deionized water. After stirring the above components according to the corresponding contents for 2 hours and mixing them uniformly, they were aged at 60° C. for 24 hours, and filtered with a 0.5-micron medium-speed filter paper to obtain a digital printing active ink.

Embodiment 3

[0052] Reactive dye inkjet ink for digital printing, which includes the following components by weight percentage: C.L. reactive blue 4917%, 1,2 propylene glycol 11%, alkoxylated alcohol 1%, trimethylolpropenoate 1.0%, EDTA Disodium 1.4%, thiazole fungicide 0.4%, caprolactam 8%, triethylamine 2%, NP-102%, and the rest are deionized water. After stirring the above components according to the corresponding contents for 2 hours and mixing them uniformly, they were aged at 60° C. for 24 hours, and filtered with a 0.5-micron medium-speed filter paper to obtain a digital printing active ink.

Abstract

The invention discloses an active ink for digital printing and a preparation method thereof. The active ink is made of the following components, and the content of each component is calculated by weight percentage: active dye 10%-30%, viscosity regulator 10-30%, surface tension regulator 0.2%-2%, bactericide 0.2% % to 0.5%, co-solvent 5% to 10%, penetrant 0.5 to 4%, stabilizer, and the balance is deionized water; the stabilizer is selected from one of the following combinations: ① triethylamine 0.5 to 3% +Trimethylol acrylate 0.6~1.0%+Disodium EDTA 1.4~1.8%, ②Triethylamine 0.5~3%+Butyl triethylene glycol 0.6~1.2%+Disodium EDTA 1.4~1.8%, ③ Triethylamine 0.5-3% + triethylene glycol butyl ester 0.4-0.8% + N-2 hydroxyethylpiperazine 0.4-0.8% + EDTA disodium 0.6-1.0%. The stabilizer used in the ink of the present invention can improve the stability of the ink while avoiding the problem that the traditional phosphate is likely to cause environmental pollution. The ink preparation method provided by the invention can significantly reduce the impurity content in the ink, and is economical and environmentally friendly; the prepared active ink is suitable for single-pass printing.

Description

technical field [0001] The invention relates to a reactive ink for digital printing and a preparation method thereof. Background technique [0002] The traditional printing process requires a lot of water, and the waste liquid, waste water, and waste pulp produced have caused great pollution to the environment and brought a lot of trouble to people. Different from the traditional printing process, digital printing does not require complex plate making. During the entire printing process, no water is required, and no staff is required to adjust the color paste. After the machine is set up and the ink cartridges are installed, When the print mode is activated, the machine dispenses the dye as needed, jetting the ink directly onto the fabric. At the same time, in the process of jet printing, the dyes produced by the printing machine during the washing process during the mixing process are avoided, so there is no discharge of dye liquid and color paste, and no pollutants will a...
