Helix for Textile Dyeing
The Helix is engineered to readily meet the requirements needed to do textile dyeing or other impregnations.
The Helix configured to do textile dyeing consists of:
- CO2 pump module
- Base unit - for the dye take-up module
- A second base unit - for dyeing
- 2 vessels - size determined by individual requirements
Optionally:
- Supercritical CO2/dye recirculating pump
- CO2 recycling module
Applied Separations can also scale-up the textile dyeing system to larger sizes as shown here with a 40 liter vessel system built for ITRI in Hsin Hsu, Taiwan. The 40 liter system is completely automated and can even be controlled from the other side of the world through the internet.

Using Supercritical Fluids for Textile Dyeing
The conventional dyeing of textiles requires that an excess of dye is dissolved or in some way "taken-up" in an aqueous or solvent solution. The dye mix is then pumped into a vat containing holding the textile. Typically there is agitation or the dye is recirculated several times through the cloth. At the end of the cycle, the dye mix is pumped to the waste treatment facility. Dyes are notoriously difficult to treat. The process is decidedly unfriendly to the environment.
