Fabric heat treatment unit - has serpentine fabric pathways at entry-exit to prevent vapour escape

The desorption chamber outside the exit gap from the steaming chamber houses the guide rollers for the fabric movement. A suction fan is connected to the desorption chamber linked to a condensate collection unit. At the outlet there is a serpentine path for the fabric formed by guide rollers between barriers. The suction fans at the entry and exit of the steam chamber are linked to the condensate collection vessel through coolers. The system allows the continuous treatment of a fabric with an azeotropic mixt. of water and an organic solvent, with effective vapour removal from the fabric, without allowing escape into the ambient atmos.
