A METHOD OF PRODUCING A STABLE ELASTICIZED YARN FROM A SINGLE THREAD OF SYNTHETIC FIBERS WHICH COMPRISES, IN COMBINATION, THE STEPS OF TWISTING SAID THREADED ABOUT ITS LONGITUDINAL AXIS IN A FIRST DIRECTION TO IMPART TO SAID THREAD A FIRST PREDETERMINED NUMBER OF CORRESPONDINGLY DIRECTED TURNS PER UNIT LENGTH, TREATING SAID TWISTED THREAD WITH SATURATED STREAM AT A PREDETERMINED TEMPERATURE TO FIX AND STABILIZE SAID THREAD, THEREAFTER TWISTING SAID THREAD IN A SECOND DIRECTION WHICH IS OPPOSITE TO SAID FIRST DIRECTION AND TO AN EXTENT WHICH IS GREATER THAN SAID TWISTING IN SAID FIRST DIRECTION TO IMPART TO SAID THREAD A SECOND PREDETERMIND NUMBER OF TURNS PER UNIT LENGTH WHICH IS GREATER THAN AND DIRECTED OPPOSITELY TO SAID FIRST NUMBER OF TURNS, ALLOWING SAID THREAD TO EXPAND FREELY, THEREAFTER TREATING SAID THREAD A SECOND TIME WITH SATURATED STREAM AT A PREDETERMINED TEMPERATURE HIGHER THAN SAID FIRST TEMPERATURE, WHEREBY SAID THREAD IS FIXED AND STABILIZED, AND FINALLY, AFTER SAID FIXING AND STABILIZING, TWISTING SAID THREAD A SECOND TIME IN SAID FIRST DIRECTION
