Digital inkjet thermal transfer printing water-based ink for textiles and preparation method of ink

[0027] Example 1

[0028]Fully dissolve 7 parts of dispersant MF (Shangyu Haili Chemical) and 1 part of dispersant SILCO SPERSE HLD-11/C (Germany SILCONA Company) in 60 parts of deionized water, then add 0.3 parts of wetting agent Surfynol AD01 (USA Air Chemicals), 15 parts of glycerin, 5 parts of ethylene glycol, 5 parts of isopropanol, 0.2 parts of defoamer Surfynol DF-37 (Air Chemicals, USA) and 0.05 parts of preservative Kathon LXE (Rohm and Haas, USA), After fully stirring and mixing, add 10 parts of Disperse Red 60 (Zhejiang Jihua Group), and stir again to obtain a pre-dispersion. Pass the predispersion through the containing The zirconia beads are refined for 4 times in a horizontal sand mill, filtered through a 150-180 mesh stainless steel filter, and then ultra-finely dispersed by a 120Mpa ultra-high pressure homogenizer for 2 times, so that the particle size of the disperse dye particles is 80- 200nm, nano-membrane (US Pall Company, pore size 0.5μm) filtration, discharge, that is to obtain water-based digital inkjet thermal transfer printing ink for textiles. The particle size of the obtained water-based ink is 180nm, the pH value is 8, the viscosity is 2.5mPa.s, the surface tension is 31mN/m, and the conductivity is 8000μs/cm.

[0029] Example 2

[0030] Fully dissolve 6 parts of dispersant Reax85A (U.S. Westvaco Company) and 2 parts of dispersant PEG600 (polyethylene glycol) in 60 parts of deionized water, then add 0.5 parts of wetting agent SILCO WET D500 (Germany SILCONA Company), 15 parts Glycerin, 5 parts of ethylene glycol, 5 parts of ethanol, 0.3 parts of defoamer Surfynol 110D (Air Chemicals, USA) and 0.02 parts of preservative Nipacide HF-1 (Clariant), mixed in the solution obtained above, mixed thoroughly Finally, add 8 parts of Disperse Red 60 and stir again to obtain a pre-dispersion. Pass the predispersion through the containing The zirconia beads are refined for 4 times in a horizontal sand mill, filtered through a 150-180 mesh stainless steel filter, and then ultra-finely dispersed by a 120Mpa ultra-high pressure homogenizer for 2 times, so that the particle size of the disperse dye particles is 80- 200nm size, nano-membrane (US Pall Company, pore size 0.5μm) filtration, discharge, that is to get water-based digital inkjet thermal transfer printing ink. The particle size of the obtained water-based ink is 190nm, the pH value is 8, the viscosity is 2.5mPa.s, the surface tension is 31mN/m, and the conductivity is 12000μs/cm.

[0031] Example 3

[0032] Fully dissolve 7 parts of dispersant NNO and 3 parts of dispersant Pingping plus O in 75 parts of deionized water, then add 0.3 parts of wetting agent Surfynol420 (Air Chemicals of the United States), 15 parts of glycerin, 5 parts of ethylene glycol, and 5 parts of iso Propanol, 0.3 parts of defoamer Surfynol DF-37 (Air Chemicals, USA) and 0.05 parts of preservative Kathon LXE (Rohm and Haas, USA) were mixed in the solution obtained above. Red 60, stir well again to obtain a pre-dispersion. Pass the predispersion through the containing The zirconia beads are refined for 4 times in a horizontal sand mill, filtered through a 150-180 mesh stainless steel filter, and then ultra-finely dispersed by a 120Mpa ultra-high pressure homogenizer for 2 times, so that the particle size of the disperse dye particles is 80- 200nm size, nano-membrane (US Pall Company, pore size 0.5μm) filtration, discharge, that is to get water-based digital inkjet thermal transfer printing ink. The particle size of the obtained water-based ink is 190nm, the pH value is 8, the viscosity is 2.8mPa.s, the surface tension is 31mN/m, and the conductivity is 10000μs/cm.
