Abstract or the Disclosure Thermoplastic yarn is textured while at a tempera- ture at or above its plasticizing temperature by impingement thereon of a converging stream of compressible fluid. Prior to impingement, the fluid stream is passed through a convergent/divergent flow path to accelerate the inpinging fluid to a velocity in excess or Mach 1. The yarn is under tension at the point of fluid impingement. Subsequently the yarn is cooled below its plasticizing temperature while in a substantially tensionless condition. Apparatus for performing the texturing process is disclosed.
