Embodiment 1

[0025] Preparation of blue ink:

[0026] Weigh 2.4kg solvent-based resin 1652, 10kgDMF, 10kg diethylene glycol butyl ether, 6kg dipropylene glycol methyl ether, 2.4kg2-pyrrolidone, 6kg ethylene glycol butyl ether acetate, mix well at room temperature, add 1.2kg C .I. Disperse Blue 14 was dissolved in a high-shear emulsifier at a speed of 800 rpm for 3 hours, and then filtered through a filter with a pore size of 1 μm to obtain a blue sublimation liquid ink. The ink has a viscosity of 8.1 cP and a surface tension of 30.1 mN / m at a temperature of 25°C.

Embodiment 2

[0028] Preparation of red ink:

[0029] Weigh 0.6kg polyester resin ES-100, 15kgDMSO, 6kg dipropylene glycol butyl ether, 5.4kg 2-pyrrolidone, 9kg ethylene glycol butyl ether acetate, mix well at room temperature, add 2.0kg C.I. Disperse Red 11 , using a high-shear emulsifier to dissolve at a speed of 800 rpm for 3 hours, and then filter through a filter with a pore size of 1 μm to obtain a red sublimation liquid ink. The ink has a viscosity of 4.1 cP and a surface tension of 30.1 mN / m at a temperature of 25°C.

Embodiment 3

[0031] Preparation of yellow ink:

[0032] Weigh 2.4kg polyester resin ES-VB-220A, 10kgDMF, 10kg DMSO, 6kg diethylene glycol butyl ether acetate, 2.4kg2-pyrrolidone, 6kg ethylene glycol butyl ether acetate, and mix them uniformly at room temperature. Add 1.2kg of C.I. Disperse Yellow 64, and use a high-shear emulsifier to dissolve at a speed of 800 rpm for 3 hours, and then filter through a filter with a pore size of 1 μm to obtain a yellow sublimation liquid ink. The ink has a viscosity of 7.9 cP and a surface tension of 31.5 mN / m at a temperature of 25°C.

Abstract

The invention provides a solvent type digital ink-jet printing dye sublimation ink and a preparation method thereof. The ink comprises the following components in percentage by mass: 1 to 10 percent of disperse dye, 0.5 to 7 percent of resin and 20 to 95 percent of organic solvent. The preparation method comprises the following steps of: uniformly mixing 0.5 to 7 percent of resin and 20 to 95 percent of organic solvent at a normal temperature; adding 1 to 10 percent of disperse dye into the mixture; dissolving the disperse dye with a high-shear emulsifying machine at a rate of between 400 and1,000 rpm for 0.5 to 5h; and filtering the mixture with a filter of which the aperture is 0.2 to 2 mu m to obtain the solvent type digital ink-jet printing thermal-sublimation ink. The ink is not influenced by the temperature change of a printing environment, and has the advantages of good injection stability and storage stability, simple preparation process and low energy consumption.

Description

technical field [0001] The invention belongs to the field of ink and its preparation, in particular to a solvent-based digital inkjet printing sublimation ink and a preparation method thereof. Background technique [0002] Inkjet printing technology plays a pivotal role in the field of textile printing. The inks that can be used for textile inkjet printing can be divided into two categories: dye-based inks and pigment-based inks according to different colorants. Although pigment-based inks have good light fastness, due to insufficient adhesion of pigment-based inks to fabrics in textile ink-jet printing, dyes are usually used as colorants in textile ink-jet printing. Dye-based inks can be further divided into reactive dye inks, acid dye inks and disperse dye inks. Reactive dye inks and acid dye inks are mainly used for cotton fabrics, silk fabrics, and nylon fabrics, while disperse dye inks are mainly used for polyester fabrics or polyester-containing blended fabrics. Due ...
