Waterless Textile Dyeing with Supercritical Fluid

There is a great concern these days about water - do we have enough? How can we consume less? One very large consumer of water is the textile dying industry. 

Traditionally, 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.

Our technique replaces the aqueous or solvent solution with supercritical CO2.
