The invention belongs to the technical field of spinning equipment, and discloses a spinning device for producing bright and clean yarn through spiral airflow. The spinning device comprises an upper twisting wheel and a lower twisting wheel, wherein yarn penetrates through the space between the upper twisting wheel and the lower twisting wheel and then penetrates through a yarn passing groove of a spiral airflow generator. The side edge of the spiral airflow generator is provided with two holes which are respectively a spiral air-blowing hole in the upper portion and a horizontal air-blowing hole in the lower portion, wherein the spiral air-blowing hole is connected with an external spiral air inlet pipe, the horizontal air-blowing hole is connected with an external horizontal air inlet pipe, the spiral air-blowing hole is tangent with the inner wall of the yarn passing groove and is arranged at a certain angle so that the airflow can rotate spirally along the inner wall of the yarn passing groove to blow yarn hairness to be twisted in the twisting direction of the yarn, and then the yarn hairness is fixed along with the twisting of the yarn. By means of the spinning device for producing the bright and clean yarn through the spiral airflow, the amount of generated yarn hairness can be reduced obviously, the produced bright and clean yarn is smooth in surface and high in strength, and a fabric made from the bright and clean yarn is fine and smooth in hand feel, comfortable to ware and bright-colored in gloss.
