Problems solved by technology

[0003] When inkjet ink is applied in the textile industry, the stability, color fastness, washing fastness, and hydrolysis degree of the ink all need to meet higher requirements. Most of the inks used in the existing textile industry are reactive dyes (also known as reactive dyes). dyes), acid dyes or disperse dyes, among which the pH value of reactive dyes is easy to increase, and it is easy to undergo hydrolysis or alcoholysis in water, thereby reducing the color fastness of textile printing. Generally, the validity period does not exceed three months. Drops, easy to fade, ink is easy to decompose, can not be stored for a long time, and because it contains a lot of impurities, it is easy to block the nozzle
[0004] Chinese patent CN100381634C discloses a kind of textile digital printing reactive dye inkjet ink and its production process, which includes reactive dye, humectant, descaling agent, bactericide, pH value control agent, penetrating agent, deionized water, but due to the Textile digital printing reactive dye inkjet ink uses reactive dyes that are prone to hydrolysis or alcoholysis in water, so its color strength, color fastness and washing fastness are not good
[0005] Chinese patent CN100381634C discloses a kind of textile digital printing reactive dye inkjet ink and its production process, which includes reactive dye, humectant, descaling agent, bactericide, pH value control agent, penetrating agent, deionized water, but due to the Textile digital printing reactive dye inkjet ink uses reactive dyes that are prone to hydrolysis or alcoholysis in water, and its color strength, color fastness and washing fastness when applied to silk, wool, nylon and leather are not good
Chinese patent CN100384945C discloses a class of acid dye composition, which consists of weak acid dye, auxiliary agents and stabilizers from natural products, uniformly mixed with general methods, and this patent improves the coloring strength and color fastness. , but because the composition does not use suitable additives, it cannot meet the requirements of printing performance

Embodiment 1

[0029] Include the following components by weight percentage: C.I. Acid Dye Black 168 6%, C.I. Acid Dye Black 26 2%, Polyvinylpyrrolidone 1%, Diethylene Glycol 15%, Alkoxylated Alcohol EH-6 0.3%, Diethyl 3% glycol ether, 0.2% monoethanolamine, 0.5% 2-methyl-4-isothiazolin-3-one, and the rest is deionized water.

[0030] The above components were fully stirred for 2 hours at a temperature of 45°C and a rotational speed of 150 rpm to obtain a mixed solution. The mixed solution was cooled to room temperature through a cooler, and the cooled mixed solution was sequentially passed through a pore size of 0.45 μm and The acid dye inkjet ink for textile inkjet printing can be prepared by filtering through a microporous filter of 0.20 μm.

Embodiment 2

[0032] The following components are included in terms of weight percentage: C.I. Acid Dye Blue 227 1%, C.I. Acid Dye Blue 229 8%, Polyethylene Glycol 6%, 1,5-Pentanediol 12%, Alkoxylated Alcohol EH-6 1.0 %, triethylene glycol ethyl ether 3%, diethanolamine 0.2%, 2-methyl-4-isothiazolin-3-one 0.5%, and the rest is deionized water.

[0033] The above components were fully stirred for 2 hours at a temperature of 40°C and a rotational speed of 220 rpm to obtain a mixed solution. The mixed solution was cooled to room temperature through a cooler, and the cooled mixed solution was sequentially passed through a pore size of 0.45 μm and The acid dye inkjet ink for textile inkjet printing can be prepared by filtering through a microporous filter of 0.20 μm.

Embodiment 3

[0035] According to the weight percentage, it includes the following components: C.I. Acid Dye Red 52 0.5%, C.I. Acid Dye Red 249 8%, 1,2,3-Glycerol 10%, 4-Butyrolactam 10%, Alkoxylated Alcohol EH -6 0.8%, propylene glycol methyl ether 1%, triethanolamine 0.7%, 2-methyl-4-isothiazolin-3-one 0.2%, and the rest is deionized water.

[0036] The above components were fully stirred for 2 hours at a temperature of 60°C and a rotational speed of 160 rpm to obtain a mixed solution. The mixed solution was cooled to room temperature through a cooler, and the cooled mixed solution was sequentially passed through a pore size of 0.45 μm and The acid dye inkjet ink for textile inkjet printing can be prepared by filtering through a microporous filter of 0.20 μm.

Abstract

The invention discloses textile inkjet printing acid dye ink comprising the following components in percentage by weight: 0.5-10 percent of acid dye, 0.5-10 percent of viscosity modifier, 5.0-20 percent of humectant, 0.2-5 percent of osmotic agent, 0.1-2 percent of pH control agent, 0.1-1 percent of disinfectant and the balance of deionized water. The invention also discloses a production method of the textile inkjet printing acid dye ink, comprising the following steps of: (1) mixing the acid dye, the viscosity modifier, the humectant, the osmotic agent, the pH control agent, the disinfectant and the deionized water for 2 hours in the rotation speed of 100-300 revolutions per second at the temperature of 40-60 DEG C; and (2) cooling the mixture to normal temperature and sequentially filtering the mixture by micropore filters with pore diameters of 0.45 micrometer and 0.20 micrometer. The textile inkjet printing acid dye ink can be used for the inkjet printing of true silk, wool, chinlon, leather, and the like.

Description

technical field [0001] The invention relates to an inkjet printing ink and a production method thereof, in particular to an acid dye ink for textile inkjet printing and a production method 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 hydrolysis degree of the ink all need to meet higher requirements. Most of the inks used in the existing textile industry are reactive dyes (also known as reactive dyes). dyes), acid dyes or disperse dyes, among which the pH value of reactive dyes is easy to increase, and it is easy to undergo hydrolysis or alcoholysis in water, thereby reducing the color fastness of textile printing.
