Abstract
Process for obtaining threads, filaments and thermoplastic fibers with permanent curling or waving, characterized in that the thermoplastic yarn to be treated, unwrapped from a feeding package, is continuously passed at a determined linear speed, through an area heated at an elevated temperature below the melting point of the thermoplastic material, subjecting it to a tension less than the ductility value of the heated yarn; continuously twisting the yarn immediately before and/or during its passage through the heated zone; continuously cooling the yarn once it has passed through the heated zone; untwist it continuously after the yarn has been cooled; and finally wind the thread continuously.
