ABSTRACT:
A process for the preparation of texturized multifilamentary polyester yarn possessing a stable crimp, in which the yarn passes first through a crimping device comprising an injector where the yarn is subjected to a stream of hot fluid which separates the filaments, and thereafter through a stacking nozzle to cause crimping, characterized in that the fluid is fed in at a temperature below the second order transition temperature of the polyester yarn, which feeding temperature is usually between 95.degree. and 220.degree. C., and in that the stack, after it issues from the nozzle is kept in the compressed state, subjected in this state to a high pressure of the order of 20 to 200 kg/cm.sup.2, and kept at ambient temperature or subjected to a heat treatment at a temperature below the second order transition temperature of the polyester yarn, which is usually at a temperature of up to about 220.degree. C., for a period of time ranging from one minute to 150 minutes.
Polyester yarn possessing a stable crimp and fiber prepared by cutting the said yarn, as well as the textile articles comprising this yarn are also disclosed.
