Clean(er) Polyester
Polyester’s ubiquity in the outdoor market
and its consequential impact have given rise
to technologies aimed at improving the dye
process on several fronts. One of which was
featured in

,
“Dyeing to be Clean,” a look into waterless
supercritical CO2 dyeing. Another new ap-
proach, with potential lower cost of process
integration and with low or no water usage
could well be a formidable competitor. These
two disruptive technologies have similar
ends, but the following illustrates how differ-
ent they are, starting with supercritical CO2.
A supercritical fluid (SCF) is simply a
lesser known phase of matter unlike the
very familiar solid, liquid and gas states.
The supercritical phase is where matter
transitions back and forth between a liquid
and a gas (Figure 2). The Yeh Group’s Dry-
dye Technology takes advantage of polyes-
ter’s physical characteristics and combines
them with carbon dioxide’s supercriticality to
make a waterless dye process. What makes
CO2 especially well-suited to this process is
its ability to swell polyester.
Additionally, enabled by its gas-like,
low-viscosity behavior, the dyes piggy-
Figure 2. The critical point were carbon dioxide (CO2) becomes supercritical
is at 88F/31C and 1,071 pounds per square inch/7.39 MPa (Image: Creative
