First, the pressurized gas is injected into the vortex chamber (32) from the oblique air injection holes (33) to form a swirling airflow, and then the fiber bundle (42) is output into the fiber channel (41), and the fiber bundle (42) will be sucked into the vortex chamber. In (32), then, a part of the fiber bundle (42) enters the upper channel (211) for yarn drawing under the action of the guide needle (4) to become the core fiber, and another part of the fiber bundle (42) is in the swirling airflow. The fibers in a free state are formed under the action, and rotate with the swirling airflow to wrap the core fibers, thereby forming a primary yarn (1), which enters the yarn delivery channel (21) for output outward ;

During the process of outputting the primary yarn (1) to the outside, the yin liquid nozzle (51) sprays the yin water mist to the negative powder area (22), and the powder nozzle (52) sprays it to the negative powder area (22) Nanometer white bamboo charcoal powder, so that yin water mist and nanometer white bamboo charcoal powder are distributed in the yin powder area (22); at the same time, the yang fluid nozzle (61) sprays yang water mist to the yang fluid area (23), so as to make the yang fluid Yang water mist is distributed in the area (23), the negative powder area (22) is located in the middle channel (212) of yarn drawing, and the positive liquid area (23) is located in the lower channel (213) of yarn drawing. (1) When passing through the Yin powder area (22), the side walls of the first-level yarn (1) will be coated with Yin water mist and nano white bamboo charcoal powder, and then, when passing through the Yang liquid area (23), It will be re-applied with Yang water mist to obtain secondary yarn (11), and continue to output;

The solute of the yin water mist is an anionic polyelectrolyte, and the solute of the yang water mist is a cationic polyelectrolyte.

10. the using method of the yarn drawing system of a kind of enhanced yarn antibacterial and adsorption function according to claim 9, is characterized in that:

The solute of the Yin mist is any one of polypropylene-based hydrochloride, chitosan, polydivinyl propyl dimethyl ammonium chloride, polyethylene imine, polyquaternary ammonium salt, polyvinyl pyridine or any mix;

The solute of the yang water mist is any one or any mixture of sodium alginate, hyaluronic acid, polyacrylic acid, polystyrene sulfonic acid, polyvinyl sulfonic acid, and polyvinyl phosphoric acid.
