ABSTRACT:
Processes for dyeing a hydrophobic textile fiber with a colorant material using a SCF--CO.sub.2 dyebath are described. One process employs cooling, without venting or removing CO.sub.2 from the system, to a target CO.sub.2 temperature at or below the glass transition temperature of the hydrophobic fiber, followed by the venting of the dyeing system to atmospheric pressure. The other process employs venting, without cooling, to a target CO.sub.2 density where dye is no longer soluble in the SCF--CO.sub.2, followed by cooling to a target temperature and then venting to atmospheric pressure. Optionally, the temperature of the dyeing process is established by heating the process according to a selected temperature profile.
