ABSTRACT OF THE DISCLOSURE A method for continuous wet heat treatment of a cloth in the processing thereof comprising transporting a cloth con- tinuously through a plurality of high pressure steamer bodies having different functions and being connected directly with each other under a saturated water vapor at a relatively lower temperature of about 130°C to subject the cloth to different kinds of treatments respectively therein. The apparatus there- for comprises a plurality of high pressure steamer bodies, which may have different functions, to transport a cloth con- tinuously therethrough, the said steamer bodies being composed of universal units arranged transversely, provided respectively with a cloth inlet and a cloth outlet situated at the same level and connected directly with each other by joining the cloth inlet and outlet of the adjacent steamer bodies, and either the cloth inlet or the cloth outlet of the steamer bodies situated at both ends having respectively a seal mechanism. A modification of the said apparatus comprises dividing the said high pressure steamer bodies into at least one steamer body for preliminary wet heat treatment of a cloth and two or more steamer bodies for final wet heat treatment thereof, and this apparatus is particularly suitable for dyeing a cloth containing polyester fibers by wet heat treatment to render the surface of the cloth rough by the preliminary wet heat treatment.
