Problems solved by technology

For water-based or solvent pigment-based inkjet printing inks, due to the combination of no chemical bonds or strong intermolecular forces between the pigments and polyester fabrics, the abrasion fastness of pigment-based inkjet printing inks on polyester fabrics is poor.
In addition, compared with disperse dyes, pigments generally have shortcomings such as incomplete color spectrum, not bright enough color, poor transparency, complicated ink preparation process, and high cost. Therefore, the application of pigment-based inkjet printing inks on polyester fabrics is limited. limits
At present, countries in the world have developed more water-based disperse dye inkjet printing inks, but less research on solvent-based disperse dye inkjet printing inks. So far, only the Hilord company of the United States has carried out research in this area, but there is no Have applied for a patent in any country

Embodiment 1

[0038] Preparation of red ink:

[0039]Weigh 4g of dispersant MHC80-8200 and 5g of modified xylene resin and add them to 81g of ethylene glycol butyl ether acetate, emulsify with an emulsifier for 35min, then add 10g of C.I. disperse dye red 92, disperse for 30min, and then use sand After grinding for 12 hours, take it out to get the color paste of red ink. Then weigh 25g of color paste and 25g of diethylene glycol diethyl ether, mix evenly, disperse for 20min, and filter through a microporous membrane with a pore size of 0.2-2μm to obtain a solvent-based red disperse dye inkjet printing ink. The physical properties of this ink at 24°C are as follows: surface tension 31.2mN / m (measured by BZY-2 automatic surface tensiometer), viscosity 3.50cP (measured by R / S coaxial cylinder rheometer), disperse dye particle average The particle size is 110nm (measured by a Malvern particle size tester), and the printing fluency of the ink is good.

Embodiment 2

[0041] Preparation of yellow ink:

[0042] Weigh 24.2g of dispersant Tilo-38500F3 (active ingredient 33.3%) and 5g of W30-2 silicone resin into 60.8g of diethylene glycol diethyl ether, emulsify with an emulsifier for 30min, then add 10g of C.I. disperse dye yellow 89, After dispersing for 30 minutes, grind it with a sand mill for 28 hours and take it out to obtain the color paste of yellow ink. Then weigh 20g of color paste and 30g of ethylene glycol butyl ether acetate, mix evenly, disperse for 30 minutes, and filter through a microporous membrane with a pore size of 0.2-2 μm to obtain a solvent-based yellow disperse dye inkjet printing ink. The physical properties of this ink at 24°C are as follows: surface tension 30.9mN / m (measured by BZY-2 automatic surface tensiometer), viscosity 7.59cP (measured by R / S coaxial cylinder rheometer), disperse dye particle average The particle size is 123nm (measured by a Malvern particle size tester), and the printing fluency of the ink ...

Embodiment 3

[0044] Preparation of blue ink:

[0045] Weigh 33.3g dispersant Tilo-38161 (active ingredient 30%) and 10g rosin modified mixed alkylphenol phenolic resin and join in 46.7g ethylene glycol butyl ether acetate, emulsify with emulsifier for 50min, then add 10g C.I. Disperse dye blue 77, disperse for 30 minutes, then grind it with a sand mill for 36 hours and take it out to get the color paste of blue ink. Then weigh 25g of color paste, mix with 15g of ethylene glycol butyl ether acetate and 10g of diethylene glycol diethyl ether, and after dispersing for 30 minutes, filter it with a microporous membrane with a pore size of 0.2-2 μm to obtain a solvent-based blue dispersion. Dye inkjet printing ink. The physical properties of this ink at 24°C are as follows: surface tension 29.6mN / m (measured by BZY-2 automatic surface tensiometer), viscosity 3.73cP (measured by R / S coaxial cylinder rheometer), disperse dye particle average The particle size is 132nm (measured by a Malvern part...

Abstract

The invention provides a solvent type disperse dye ink-jet printing ink and a preparation method thereof. The ink comprises the following components in percentage by mass: 1 to 10 percent of disperse dye, 1 to 15 percent of dispersant, 0.5 to 15 percent of resin and 60 to 95 percent of organic solvent. The preparation method comprises the following steps of: adding 1 to 15 percent of dispersant and 0 to 10 percent of resin into the organic solvent, and emulsifying the mixture for 20 to 60min, adding 1 to 8 percent of dye into the mixture, grinding the mixture for 8 to 40h, and obtaining a disperse dye color paste; and adding 10 to 80 percent of disperse dye color paste and 0 to 10 percent of resin into the organic solvent, and filtering the mixture with a millipore filter between 0.2 and 2 mu m to obtain the solvent type disperse dye ink-jet printing ink. The ink has the advantages of good printing smoothness, bright lustre of patterns, and excellent sunlight fastness, washing fastness and rub resistance, and can be widely applied to multiple kinds of wide, high-speed and solvent type digital printing equipment; and the preparation method is simple and practical.

Description

technical field [0001] The invention belongs to the field of ink-jet printing ink and its preparation, in particular to a solvent-type disperse dye ink-jet printing ink and a preparation method thereof. Background technique [0002] With the development and popularization of computer technology, inkjet printing technology can be widely used in various fields such as document printing, indoor and outdoor advertising inkjet printing, digital printing and textile inkjet printing. Especially in the textile industry, inkjet printing can save the production steps of printing screen, so it can save a lot of time and cost, especially for the situation of changing patterns and shapes, inkjet printing can achieve the required changes in a short time . In addition, inkjet printing inks for textiles must have good stability, high color fastness and washing fastness, etc. [0003] For polyester fabrics, the inks used in inkjet printing can be divided into two categories according to th...
