The composition comprises an air inlet 1, a fiber inlet 5, an exhaust port 7, a yarn outlet 14, and a chemical fiber filament inlet 15. The upper and lower twisters contain a matching swirling twisting part, and an eddy current field is formed inside the vortex twisting component. The short fiber and the chemical fiber filament enter the vortex twisting part respectively through the fiber inlet 5 and the chemical fiber filament inlet 15. In the eddy current field, the fiber bar is twisted to produce twisted core yarn, and the upper twister and the lower twister are connected into a whole through the interface of the required strip export 6 and the required entry 13, which are installed on the rack between the drafting area and the winding area of the spinning machine. Abstract: the invention discloses a jet vortex spinning core spun yarn processing device, comprising an upper twister and a lower twister.

The device obviously improves the production efficiency and completes the drafting of chemical filament.

The intake port 1, the fiber inlet 5, the exhaust port 7, the outlet yarn 14, and the chemical fiber filament inlet 15, are characterized by: the upper and lower twisters contain a matching swirl twisting component, and an eddy current field is formed inside the swirling twisting component. The short fiber and the chemical fiber filament enter the swirling twisting part respectively through the fiber inlet 5 and the chemical fiber filament inlet 15. In the eddy current field, the fiber bar is twisted to produce twisted core yarn, and the upper twister and the lower twister are connected into a whole through the interface of the required strip export 6 and the required entry 13, which are installed on the rack between the drafting area and the winding area of the spinning machine. Sovereignty: an air-jet spinning core spun yarn processing device consisting of an upper twister and a lower twister.
