Abstract
After a dyeing operation has been concluded, the hot dyeing liquor present in the piece dyeing jet is returned via a cooling heat exchanger in the dyeing circulation system back into the makeup storage vessel for the dyeing liquor. Thereafter, the liquor-free dyeing system, which is still under an elevated static pressure, is relieved to atmospheric whereby the dyeing system is cooled down adiabatically together with the dyed textile material present therein to such an extent that a sample can be taken therefrom rapidly and safely.
