Abstract
A process for heat-treating and, in particular, for drying and/or fixing a continuously moved fabric web in a treatment unit comprising at least two treatment zones through which the fabric web successively passes, using a hot gas stream recirculated in the treatment unit, a certain quantity of waste gas being continuously removed from the treatment unit and freed from constituents present in it and some of the waste gas thus treated being returned to the treatment unit after reheating, the rest of the waste gas being released into the atmosphere.
