Abstract
A heat treatment chamber for textile threads continuously treats the textile threads utilizing forced circulation units of a treatment fluid. The circulation units are these units being crossed consecutively by a conveyor belt that carries a lap of threads. Each circulation unit is provided with a blower and a closed circuit or an open circuit for the treatment fluid (air or steam). A heat exchanger is positioned near the conveyor belt, in such a way that the fluid crosses it and takes the desired temperature immediately before crossing the lap of threads. The heat exchanger can be formed of longitudinal tubes criss-crossed by heating or cooling fluid. Such a chamber is usable either to preheat the threads, to maintain them heated, or to cool them. The forced circulation units can ensure a gradual variation in the temperature of the threads in the same treatment chamber, or can enable a homogeneity to be obtained in a particular portion of the tunnel, by virtue of the communication between at least two forced circulation units that function in open circuit with the surrounding zone.
