Abstract
A method and an apparatus for heating and drawing a synthetic filament yarn, and wherein the yarn receives a film of water by wetting with heated water vapor before entering into a heating chamber and so that the water vapor initially condenses on the yarn as it enters the heating chamber. To this end, a water nozzle or a hot vapor nozzle may be used, which is arranged upstream of the heating chamber.
