Process for obtaining the elasticity increase of yarns formed of, or containing highly crystalline polypropylene, characterized by the fact that it comprises the twisting of yarns until they reach at least four times more than the normal twisting, the fixing of the yarn thus twisted its drying and then untwisting it and continuing to untwist it beyond its zero point.
