Abstract
The invention relates to the heat treatment of continuously moving length of textile material in a treatment apparatus with at least two successive treatment zones by means of hot gas. After it has been heated, all of the exhaust gas from the first treatment zone is introduced into the second treatment zone as fresh gas. An exhaust gas branch stream drawn off at the end of the second treatment zone is afterburned. The exhaust gas branch stream which has been heated in this way first of all preheats the second exhaust gas branch stream coming from the second treatment zone, and before being discharged into the atmosphere the exhaust gas branch stream coming from the first treatment zone and the fresh air air heated. In this way extremely economic operation of the entire treatment apparatus is provided, with reliable purification and disposable of the exhaust gas.
