Abstract

Process for producing bulky synthetic polymer yarns characterized in that the yarn in the stretchable state is fed by means of feed rollers by a heating device and a false twisting device to drawing rollers that rotate at a peripheral speed greater than the speed of the yarns. Feeder rollers in an amount equivalent to the desired stretch ratio of the yarn, the yarn being heated by passing the false twisting device in such a way that the stretching occurs during a primitive stage of heating and the fixing of twisting takes place in one stage after heating, incomplete braking of the twist in the stretching zone takes place and then the crimped yarn is heated when it is in a controlled longitudinal contraction state.
