Abstract
Process for communicating a permanent ripple to synthetic threads, especially to threads based on polyesters, characterized in that the threads, formed by continuous filaments fibers (gathered, twisted or wired), are treated by a double operation of deformation and fluted in hot that sponges and shrinks the threads; making this permanent deformation by means of a subsequent fixation at an appropriate temperature, higher by 0 to 50% at the preceding temperatures, it being then possible to twist said yarns again, to the extent necessary for their use.
