[0002] At present, the most extensive method for producing core yarn is ring spinning, but some inherent drawbacks of ring spinning, such as low production efficiency and long process flow, are unavoidable. Airflow spinning, a new type of spinning technology, can also be used to spin core yarn. Compared with ring spinning, airflow spinning technology has the advantages of short process flow, high production efficiency, low cost and strong adaptability to raw materials, making airflow spinning a relatively mature and widely used new type of spinning technology, especially in the past decade.

Spinning composite yarns by combining chemical fibers and short fibers can be expected to solve this problem. However, there are many differences between airflow spinning and ring spinning in terms of spinning principle. The unwinding and feeding of core yarn for airflow spinning core yarn have not been well solved. Currently, the unwinding of airflow spinning core yarn adopts a passive unwinding method, relying on the tension in the spinning process to pull out the core yarn. This method does not control the tension of the core yarn uniformly, which affects the covering effect and quality of airflow spinning core yarn. The uneven tension control also increases the number of broken filaments, greatly affecting the spinning efficiency of airflow spinning core yarn. SUMMARY
