Notice:
1, Before fixation, washing the costuming inside out with the clean water, lest the leftover should influence on the effect of the color fixation
2, After fixation, also washing the costuming with clean water, lest should influence on the next working procedure
3, The PH also could influence the color fixation and the color and luster of the fabric, please adjust the PH according the practice
4, The increase of dosage of fixing agent and the up-down of the temperature are good to enhance the color fixation, but too high may be lead to color change
5, According to the practice , the plants could rectify technics to reach the best color fixation through the sampling
