    Abstract: An improved process for the production of springy, textured thermoplastic yarns wherein the yarns are compacted and compressed in an enclosed space by means of a flow of compressed fluid heated at a temperature that allows for the fixing of the yarn, a portion of the fluid affecting the movement of the yarn and another portion escaping to the side from the enclosed space, such process being characterized in that the escape of fluid is effected at a pressure which is lower than the feed pressure, but higher than atmospheric pressure. The apparatus for effecting such process comprises a suction nozzle constituting a passage for the yarn and a delivery tube for admission of pressurized fluid, a tubular chamber communicating with the nozzle, and having orifices therein, a housing defining a closed space enclosing at least a portion of the length of the tubular chamber and having a pressure regulation system associated therewith, and means for controlling the discharge of the treated yarn.
