ABSTRACT:
A spinning nozzle comprises first and second nozzles provided with jetting holes through which compressed air is jetted into tubular yarn passages extending along an imaginary center line of the spinning nozzle, and arranged in series coaxially with the imaginary center line, and the second nozzle is provided in its outlet end with a balloon controller having a through hole having substantially a triangular cross section. The size of the balloon is limited to that of a circle inscribed in the through hole of the balloon controller, so that twists inserted in the yarn in the second nozzle propagate stably to a portion of the yarn in the first nozzle.
