Problems solved by technology

[0006] The present invention aims at the unsatisfactory washing fastness of the current water-based pigment ink-jet printing ink on fabrics, and provides a water-based pigment ink-jet printing ink with good washing fastness and a method for preparing and using the ink-jet printing ink. Contains two polyacrylate emulsions and one polyurethane emulsion as nanocomposite adhesives, one of which is polyacrylate emulsion modified by organic fluorine has a particle size of nanometer level, and the internal crosslinking degree of the emulsion particles is relatively high, forming on the surface of the fabric. When the film is cross-linked, it does not demulsify and form a film, and it is still distributed in the form of hydrophobic nanoparticles in the composite film formed by another polyacrylate emulsion and polyurethane emulsion.

Embodiment 1

[0040] A kind of blue water-based pigment digital inkjet textile printing ink, its formula is as shown in table 1.

[0041] Table 1 Formula of blue water-based pigment digital inkjet textile printing ink:

[0042]

[0043]

[0044] Wherein, the synthetic method of described organic fluorine modified polyacrylate nanoemulsion is: 12.3g methyl methacrylate (MMA), 2.7g hexafluorobutyl methacrylate (HFBM), 0.6g emulsifier (by Xiaofan 465, sodium lauryl sulfate SDS (mixed at a mass ratio of 1:1), 0.5g of ethylene glycol dimethacrylate was added to 20g of water, stirred at a high speed of 2500rpm, and pre-emulsified for 30min to obtain monomer pre-emulsion. Then, 30 g of monomer pre-emulsion was added into the three-necked flask, the temperature was raised to 80° C., and 4 g of initiator potassium persulfate aqueous solution (concentration: 0.82%) was added to react for 30 min. Then use the dropping funnel to drop 6g initiator potassium persulfate aqueous solution (concentra...

[0055] A kind of red water-based pigment digital inkjet textile printing ink, its formula is as shown in table 2.

[0056] Table 2 Red water-based pigment digital inkjet textile printing ink formula:

[0057]

[0058] The synthesis method of the described organofluorine-modified polyacrylate nanoemulsion is the same as that in Example 1.

[0059] The preparation method of described red water-based pigment digital ink-jet textile printing ink is: press each component prescription listed in table 2, at first surfactant, nanocomposite binder, humectant, pH regulator and antibacterial The agent was added into deionized water, and then stirred with a high-speed mixer for 80min at a speed of 2000-4500rad / min to make it a uniform solvent system; then red pigment paste (purchased from Cabot (China) Investment Co., Ltd.) was added Into the above solvent system, stir with a high-speed mixer at a speed of 2000 rad / min for 30 minutes to make it a uniform ink dispersion system; finally...

Embodiment 3

[0063] A kind of yellow water-based pigment digital inkjet textile printing ink, its formula is as shown in table 3.

[0064] Table 3 yellow water-based pigment digital inkjet textile printing ink formula:

Abstract

The invention provides a water-based pigment digital ink-jet textile printing ink and preparation and use methods thereof. The water-based pigment digital ink-jet textile printing ink is characterized by containing a pigment color paste, a nano composite adhesive and deionized water, wherein the nano composite adhesive comprises a polyurethane emulsion, an organic fluorine modified polyacrylate nano emulsion and another polyacrylate emulsion. With use of the nano composite adhesive, the problem of low water washing fastness of a water-based pigment ink-jet printing ink on a printing fabric is solved emphatically, and a new solution is provided for industrialized application of the water-based pigment ink-jet printing ink in the field of fabric digital ink-jet printing.

Description

technical field [0001] The invention relates to a water-based pigment digital ink-jet textile printing ink and a preparation method thereof, and also relates to a method for ink-jet printing of the ink on fabrics. Background technique [0002] Traditional screen and rotary screen printing operations are complex and tedious, and cannot meet the requirements of high quality, small batches, diverse patterns, and individualization, while digital inkjet printing technology gets rid of the simulation of traditional printing color separation, plate making, and net making. The method has the obvious advantages of convenient operation, no pollution, low energy consumption, and high return, bringing unprecedented development opportunities to the textile printing and dyeing industry. Digital inkjet printing is to input the required printing pattern into the computer in digital form, after computerized printing color separation, scanning and editing, the digital inkjet printing machine ...
