Embodiment 1
[0025] The detailed steps of the microextraction dyeing method of reactive dyes are as follows:
[0026] (1) Dissolve 10 g of reactive red X-3B in 100 mL of acetone, add 2 mL of oleic acid, and obtain a transparent solution under ultrasound.
[0027] (2) Suction filtration of the above transparent solution under reduced pressure to obtain reactive red X-3B powder coated with oleic acid.
[0028] (3) Add the reactive red X-3B powder coated with oleic acid into 200 mL of isooctane, and disperse it ultrasonically to obtain a concentrated transparent dye solution.
[0029] (4) Take 0.1 mL of the concentrated transparent dye solution prepared in step (3) and dilute it into 20 mL of isooctane to obtain a dye solution.
[0030] (5) Put the cotton fabric (100% pass rate) that has been soaked with sodium carbonate (10g / L) solution into the dye liquor prepared in step (4), vibrate and heat to 40°C for dyeing for 30min, then heat to Fix the color at 60°C for 10 minutes.
Embodiment 2
[0032] The detailed steps of the microextraction dyeing method of reactive dyes are as follows:
[0033] (1) Dissolve 8 g of Reactive Yellow K-4G in 100 mL of acetone, add 3 mL of oleic acid, and obtain a transparent solution under ultrasound.
[0034] (2) Suction filtration of the above transparent solution under reduced pressure to obtain active bright yellow K-4G powder coated with oleic acid.
[0035] (3) Add the active bright yellow K-4G powder coated with oleic acid into 200mL isooctane, and disperse it ultrasonically to obtain a concentrated transparent dye solution.
[0036] (4) Take 0.4 mL of the transparent dye concentrated solution prepared in step (3) and dilute it into 20 mL of isooctane to obtain a dye solution.
[0037] (5) Put the cotton fabric (100% pass rate) that has been soaked with sodium carbonate (10g / L) solution into the dye liquor prepared in step (4), vibrate and heat to 40°C for dyeing for 30min, then heat to Fix the color at 100°C for 10 minutes. ...

[0039] The detailed steps of the microextraction dyeing method of reactive dyes are as follows:
[0040] (1) Dissolve 15 g of Active Turquoise Blue KN-G in 100 mL of acetone, add 4 mL of oleic acid, and obtain a transparent solution under ultrasound.
[0041] (2) Suction filtration of the above transparent solution under reduced pressure to obtain active turquoise blue KN-G powder coated with oleic acid.
[0042] (3) Add the reactive turquoise blue KN-G powder coated with oleic acid into 200mL of isooctane, and disperse it ultrasonically to obtain a concentrated transparent dye solution.
[0043] (4) Take 0.5 mL of the concentrated transparent dye solution prepared in step (3) and dilute it into 20 mL of isooctane to obtain a dye solution.
[0044] (5) Put the cotton fabric (100% pass rate) that has been soaked with sodium bicarbonate (15g / L) solution into the dye liquor prepared in step 4, vibrate and heat to 40°C for dyeing for 30min, then heat to 80°C ℃ color fixation 10m...
