[0003] When inkjet ink is applied in the textile industry, the stability, color fastness, washing fastness, and degree of hydrolysis of the ink all need to meet higher requirements. Most of the inks used in the existing textile industry are reactive dye inks, acid dyes or Disperse dyes, among them, the pH value of reactive dyes is easy to increase, and they are prone to hydrolysis or alcoholysis in water, thereby reducing the color fastness of textile printing. Generally, the validity period is not more than three months. It is easy to decompose and cannot be stored for a long time. In addition, because it contains a lot of impurities, it is easy to block the nozzle
[0004] U.S. Patent No. 5,603,756 discloses an ink for textile printing, which includes at least one reactive dye, a polyhydric alcohol, and water, wherein the ink also includes a reaction product of the reactive dye and polyhydric alcohol, but Due to the lack of proper composition of the ink used for this textile printing, the coloring power and color fastness were not good
[0005] U.S. Patent No. 6015454 discloses an ink comprising at least one reactive dye and 1,2-propanediol or N-methyl-2-pyrrolidone, which improves the coloring strength and color fastness. But for long-term storage, not easy to damage the nozzle, etc., there is still room for improvement

Embodiment 1
[0029] Include the following components by weight percentage, black reactive dye 8%, reactive dye (orange) 0.5%, ethylene glycol 10%, NMP2%, D-70.5%, triethanol 1.5%, NP-101%, all the other are to go ionized water.
[0030] Mix the above components and stir thoroughly for 0.6 hours to obtain a mixed solution. The mixed solution is allowed to stand at a temperature of 55° C. for 24 hours to mature to obtain a mature solution. The mature solution is filtered with 1 micron, 0.5 micron, and 0.22 micron filter membranes respectively. Prepared textile digital printing reactive dye inkjet ink.
Embodiment 2
[0032] Reactive dye (bright red) 3%, glycerol 10%, 2-pyrrolidone 5%, isopropanol 5%, D-70.5%, triethanol 1%, NP-151.5%, and the balance is deionized water.
[0033] The above components were mixed, fully stirred for 0.7 hours to obtain a mixed solution, and the mixed solution was left to stand at a temperature of 60°C for 30 hours to mature to obtain a mature solution, and the mature solution was filtered with 1 micron, 0.5 micron, and 0.22 micron filter membranes respectively. Prepared textile digital printing reactive dye inkjet ink.
Embodiment 3
[0035] Reactive dye (Tuilan) 5%, glycerol 15%, isopropanol 5%, 2-pyrrolidone 1%, diethanol 2%, D-70.7%, NP-152%, and the remainder is deionized water.
[0036] The above components were mixed and fully stirred for 0.8 hours to obtain a mixed solution. The mixed solution was left to stand at a temperature of 65°C for 35 hours to mature to obtain a mature solution. The mature solution was filtered with 1 micron, 0.5 micron, and 0.22 micron filter membranes respectively. Prepared textile digital printing reactive dye inkjet ink.
[0037] Each component in the above examples can be purchased from the market.

Abstract
Reactive dye ink-jetting ink for textile digital printing is disclosed. The ink includes, by weight, (a) 1-10% of dye, (b) 10-15% of a humectant, (c) 1-5% of an anti-scaling agent, (d) 0.2-1% of a sterilizing agent, (e) 1-5% of a pH value controlling agent and (f) 0.5-5% of a penetrant, with the balance being deionized water. The invention also discloses a production process of the ink. The process includes (A) mixing the dye, the humectant, the anti-scaling agent, the sterilizing agent, the pH value controlling agent, the penetrant and the deionized water at room temperature, and fully stirring the mixture for 0.5-1 h to obtain a mixed solution; (B) allowing the mixed solution to stand at 50-70 DEG C for 24-48 h to cure the mixed solution to obtain a cured mixed solution; and (C) filtering the cured mixed solution by filtration membranes having sizes of 1 micron, 0.5 micron and 0.22 micron in order to obtain a final product. The ink can be applied in paper printing, and can be adopted as the reactive dye ink-jetting ink for textile digital printing.
Description
technical field [0001] The invention relates to an inkjet ink and a production method thereof, in particular to a textile digital printing reactive dye inkjet ink and a production process thereof. Background technique [0002] Inkjet printing has been used in the textile industry for many years. This method can save the production of printing screens, so it can save a lot of time and cost. Changes required. [0003] When inkjet ink is applied in the textile industry, the stability, color fastness, washing fastness, and degree of hydrolysis of the ink all need to meet higher requirements. Most of the inks used in the existing textile industry are reactive dye inks, acid dyes or Disperse dyes, among them, the pH value of reactive dyes is easy to increase, and they are prone to hydrolysis or alcoholysis in water, thereby reducing the color fastness of textile printing.
