ABSTRACT:
A cylindrical container (1) is horizontally arranged with its longitudinal axis. The container is subdivided by a flexible membrane (5) into a larger chamber (6) for holding textile material, preferably in a receptacle (3), and dyeing liquor, and a smaller chamber (7) for a pressurized gas. An excess pressure necessary for the high-temperature dyeing process is maintained in the smaller chamber (7) to compensate for changes in the liquor volume. These changes are temperature dependent. It is sufficient if the volume of the smaller chamber (7) is smaller than one-tenth the volume of the larger chamber (6).
