Super critical Co2 Dyeing Device
Supercritical CO2 Dyeing Device is a novel waterless dyeing device. By means of CO2 fluid to substitute water which is used in the course of traditional dyeing and printing, it realizes real waterless dyeing. The supercritical CO2 fluid dyeing device is mainly used in dyeing of synthetic fiber and natural fiber, desizing and functional finishing of fabric.
Technical index;
The maximum pressure is 30MPA
The maximum temperature of media is 200 degree.
The volume of the dyeing kettle is 24L and the standard yard bobbins are 165*152*6 pieces
Main Characteristics:
1,The absorbing rate of dyestuff is 98% so it has high dye uptake rate and good dye leveling.
2,In the course of dyeing, the Super Critical CO2 fluid is dynamically circulated.
3,The Super Critical CO2 fluid has function of both diffusion from thr inside corre to the outside core and diffusion from the outside core to the inside core.
4. The residue dyestuff is retrieved therefore the utilization rate of dyestuff can reach 98%.
5. The whole course of dyeing is automatically controlled by computer.

- Low Critical temperature suitable for extraction and purification of heat sensitive compound.
- Being capable to provide inert environment to avoid oxidation of products and affection of effective content of extracts.
3. Fast extraction speed, no toxicity, non-flammable, safe application and no pollution upon environment.
4. No residue of solvent, no nitrate and ions of heavy metal.
The Super Critical fluid technology is a new-type separation technology in modern chemical separation. The Super Critical extraction takes CO2 as the solvent. As CO2 fluid under Super Critical state has larger density and dielectric constant, larger dissolvability against substances, which can change abruptly when pressure and temperature change therefore it has not only the selection of dissolvability against substances, the separation of the solvent with the extracted substances is also easily. The Super Critical CO2 extraction is specially suitable for fine separation of different components, i.e. Super Critical fine distillation.
