Vortex spinning is a new spinning method that uses a fixed vortex spinning tube instead of a high-speed spinning rotor. In a sense, vortex spinning is the real open-end spinning. The fiber sliver is fed by the cotton feeding roller, and is opened into single fibers by the licker-in roller, and fed into the vortex tube at a high speed from the cotton conveying pipe by the action of the air flow. The vortex tube consists of a core tube and an outer tube. There are three tangential air inlets on the outer pipe, and the lower end is connected with the blower. The blower continuously extracts air from the pipe, and the outside air enters the vortex pipe along the air inlet to generate a vortex-like airflow. When the rotating upward airflow reaches the core tube, it merges with the fibers entering the cotton conveying pipe, and forms a condensed fiber ring along the inner wall of the vortex tube, which stably revolves around the axis of the vortex tube and rotates at high speed to twist the fibers into yarn. The yarn is continuously drawn out from the yarn guide hole by the take-out roller and wound into a bobbin. The main feature of vortex spinning is the elimination of high-speed rotating spinning components. Due to the use of airflow twisting, the problem of rotational inertia and bearing load caused by high-speed twisting components (such as the rotor of open-end spinning), and the problem of increased spinning tension due to the balloon formed by spinning (such as ring spinning).
Short process flow and high production rate
Vortex spinning is directly spun from fiber sliver into cheese, so like other new types of spinning, the two processes of roving and winding can be omitted. Due to the low end breakage rate of eddy current spinning, the return loss is small, and the completion rate is as high as 99%.
Strong spinnability, suitable for fleece products
Vortex spinning can spin 38~60mm fiber length, pure and blended cotton fiber and chemical fiber. The yarn structure is relatively bulky, so its dyeing, absorbent, and air permeability are better, and the anti-pilling and abrasion resistance of the yarn are also better. The yarn count range is limited to medium and low count yarns, which should be used as pile products. Such as 38mm long chemical fibers (acrylic, vinyl, viscose, etc.), spinning 6~12 inch yarn, woven into fleece, fleece pants, scarves, cushions, sofas, furniture cloth and small tablecloth and other knitted fleece product.
