Abstract
Carpet yarns which have been previously mechanically compressed, are heat set in a yarn heat treating chamber by superheated steam. The yarn treating chamber operates under atmospheric pressure. Several yarns are passed through the yarn treating chamber on respective perforated conveyor belts. The steam is conducted so that it is forced to flow downwardly through the yarns and through the permeable conveyor belts. To avoid the formation of condensate water on the conveyor belts, the belts are in the form of nonmetallic nets, upon which the yarns are deposited in the form of loops.
