ABSTRACT:
A process for the relaxation of fabric containing polyurethane yarn includes the steps of forwarding the fabric continuously through a treatment region in which it is subjected to the action of a swelling agent, for example a chlorinated hydrocarbon, which swells the polyurethane yarn, the treatment being such that the modulus of the yarn is reduced by no more than 12.5 percent, and drying the yarn after it has left the treatment region.
