When the air flow that rotates Polyester Sd Yarns Suppliers reaches the core tube, it merges with the fibers entering the cotton pipe, forming a condensed fiber ring along the inner wall of the vortex tube, and steadily rotates around the axis of the vortex tube at high speed to twist the fiber into a yarn. The yarn count range is limited to medium and low count yarns, which is suitable for raising products. Due to the elimination of the roving frame, spinning frame and automatic winder to reduce the area and labor and investment, it has its unique advantages, and it will further replace ring yarn and air-jet yarn in the field of knitting yarn. Fast speed and high output The spinning speed of the vortex spinning machine is 100_200m / min
, and the practical speed is generally 100_160m / min. The yarn is continuously drawn out from the yarn guide hole by the drawing roller and wound into a package. Because vortex spinning has no high-speed rotating parts, there is no problem of high-speed bearing lubrication, less wear and tear, less noise, and easy maintenance. The outside air enters the vortex tube along the air inlet and generates a vortex-like air flow. 1) The range of suitable raw materials for vortex spinning is limited to short chemical fibers and medium-long fibers. [What are the advantages of vortex spinning] 1.
Therefore, its spinning speed is unlikely to have a breakthrough. 4) Due to poor fiber straightness, the coagulation process of vortex spinning is too short, which makes the structure of the yarn loose, and the strength of the yarn is low, so its products are also limited, only suitable for chemical fiber raw materials and spinning thick size Knitting yarns or thick pile yarns and other products that do not require high strength, or core-spun yarns with filaments as the core. Because the vortex tubes are stationary and have no high-speed rotating parts, the joints are very convenient and simple. No special requirements for front spinning equipment, temperature and humidity.
