Abstract
This invention discloses a supercritical carbon dioxide fluid dyeing technique. The carbon dioxide heated is suppressed into dye tank and mixed with the dye to form blending solution. Blending solution is pumped into dye tank after cycle. The solution is contacted to tissues in the tank, and then it is absorbed, dissolved, then twice again absorbed and dissolved, so the dyeing is finished. The rest blending solution after dyeing is pumped into separator through circulating pump, and then carbon dioxide and dye are separated. There is no assistant in all process, cost is saved, the carbon dioxide can be cycle used and no green house effect, the inhalation rate can reach 98%, and dyeing time is short. There is no need of reduction clearing after dyeing; the rest dyeing can be reverted to powder type, so the coloring utilization ratio can be increased.
