Example Embodiment

[0032] Example 1

[0033] Mix 5 g of red reactive dye with 0.7 g of uniformly dispersed cellulose nanosphere suspension, stir well, add 1 g of sodium dodecyl sulfonate, and stir for 30 min with ultrasonic. Then add 3 g of glycerol and 0.01 g of silver nitrate, and stir well. Adjust the pH value of the solution to 7.0 with 2 mol / L disodium hydrogen phosphate-sodium dihydrogen phosphate buffer. Stir fully at 50℃ for 1 h, then cool to room temperature, continue stirring for 0.5 h, and let stand for 3 h at 50℃ for maturation; repeat filtration through a nanofiltration membrane with a pore size of 500 nm for three times, ultrasonically disperse and remove The air bubbles in the solution can produce nano-ink for silk printing.

Example Embodiment

[0034] Example 2

[0035] Mix 10 g of cyan reactive dye and 2 g of uniformly dispersed suspension of cellulose nanocrystalline spheres, stir well, and then add 2 g of sodium dodecyl sulfonate and stir for 50 min with ultrasonic. Then add 3 g ethylene glycol and 0.2 g zinc nitrate respectively, and stir well. Adjust the pH of the solution to 7.3 with 0.05mol / L phthalic acid-hydrochloric acid buffer. Stir fully at 65℃ for 1 h, then cool to room temperature, continue to stir for 0.5 h, and let stand for 3 h at 70℃ for maturation; repeat filtration through a nanofiltration membrane with a pore size of 100 nm for three times, ultrasonically disperse and remove The air bubbles in the solution can produce nano-ink for silk printing.

Example Embodiment

[0036] Example 3

[0037] Mix 15 g of red reactive dye with 0.5 g of uniformly dispersed suspension of cellulose nanospheres, stir thoroughly, and then add 0.5 g of sodium lauryl sulfate and stir ultrasonically for 40 minutes. Add 1 g of diethylene glycol and 0.02 g of silver nitrate, and stir thoroughly. Adjust the pH of the solution to 7.8 with 1mol / L disodium hydrogen phosphate-citrate buffer. Stir fully at 70℃ for 1 h, then cool to room temperature, continue to stir for 0.5 h, and let stand for 3 h at 65℃ for maturation; repeat filtration through a nanofiltration membrane with a pore size of 500 nm for three times, ultrasonically disperse and remove The air bubbles in the solution can produce nano-ink for silk printing.

Abstract

The invention relates to a preparation method of nano ink based on cellulose nanosphere as dispersant and for silk broadcloth printing. The nano ink is characterized by comprising 5-30% of active dyes, 0.5-3% of a surface active agent, 0.3-5% of a dispersant, 1-10% of a moisturizing agent, 0.01-2% of a bactericide, 0.001-2% of a pH buffer and deionized water. The invention uses cellulose nanospheres as the dispersant, so that charged groups on the surface and dye molecules form electrostatic interactions to prepare the highly dispersed nano ink. The preparation process is simple and easy to operate, has no pollution to the environment, and is applicable to industrial production; the prepared ink has the advantages of small controllable size, good storage stability, adjustable viscosity and conductivity, printing fluency, complete chromatogram and bright color.

Description

Technical field [0001] The present invention involves the preparation technology for digital printing silk textiles, and specifically involves a preparation method for nano -ink ink based on fiber nano -based silk printing agent. Background technique [0002] Digital inkjet printing is entered the required pattern into the computer through various input methods (scanners, digital cameras, etc.).In the mouth, use the RIP software to spray the ink (dedicated dyeing solution such as activity, restoration, decentralization, acidic, acidic, etc.) to various fabrics through the jet system. After processing, it obtains textiles printed with high -precision patterns.In addition, C, M, Y, K (green, red, yellow, black) four -color ten -color ten -color ten -color print head can printed 16.7 million colors, and various prints can be achieved. [0003] Compared with traditional printing, this technology has abandoned the process, production, network and carving in traditional printing. It ha...
