Embodiment 1
[0029] Include the following components by weight percentage, black reactive dye 8%, reactive dye (orange) 0.5%, ethylene glycol 10%, NMP2%, D-70.5%, triethanol 1.5%, NP-101%, all the other are to go ionized water.
[0030] Mix the above components and stir thoroughly for 0.6 hours to obtain a mixed solution. The mixed solution is allowed to stand at a temperature of 55° C. for 24 hours to mature to obtain a mature solution. The mature solution is filtered with 1 micron, 0.5 micron, and 0.22 micron filter membranes respectively. Prepared textile digital printing reactive dye inkjet ink.
Embodiment 2
[0032] Reactive dye (bright red) 3%, glycerol 10%, 2-pyrrolidone 5%, isopropanol 5%, D-70.5%, triethanol 1%, NP-151.5%, and the balance is deionized water.
[0033] The above components were mixed, fully stirred for 0.7 hours to obtain a mixed solution, and the mixed solution was left to stand at a temperature of 60°C for 30 hours to mature to obtain a mature solution, and the mature solution was filtered with 1 micron, 0.5 micron, and 0.22 micron filter membranes respectively. Prepared textile digital printing reactive dye inkjet ink.
Embodiment 3
[0035] Reactive dye (Tuilan) 5%, glycerol 15%, isopropanol 5%, 2-pyrrolidone 1%, diethanol 2%, D-70.7%, NP-152%, and the balance is deionized water.
[0036] The above components were mixed and fully stirred for 0.8 hours to obtain a mixed solution. The mixed solution was left to stand at a temperature of 65°C for 35 hours to mature to obtain a mature solution. The mature solution was filtered with 1 micron, 0.5 micron, and 0.22 micron filter membranes respectively. Prepared textile digital printing reactive dye inkjet ink.
[0037] Each component in the above examples can be purchased from the market.
