Production practice shows that vortex spinning also has some limitations in the development process
a. The range of suitable spinning raw materials for vortex spinning is limited to short chemical fibers and medium and long fibers. Due to the quality of the yarn, the competitiveness in the field of fine yarn is not strong.
b. The yarn structure of vortex spinning is relatively loose, and the long segment uniformity is good, but the strength is low and unstable, which limits its development to the field of fine yarn.
c. Although the vortex spinning uses air vortex instead of the rotor of the rotor, it overcomes the problem of wear and tear caused by the high-speed rotation of the rotor and the problem of excessive bearing load, but it still cannot solve the problem of the free end yarn tail in the vortex. The yarn arm formed when the tube rotates at high speed, which leads to the problem of large centrifugal force and tension. Therefore, it is impossible to have a breakthrough in the spinning speed.
d. Due to the poor straightness of the fibers, the condensing process of the vortex spinning yarn is too short, which makes the structure of the yarn looser and the strength of the yarn is low. Therefore, its product has its limitations, and it is only suitable for chemical fiber raw materials and spinning thick yarns. Products that do not require high strength, such as knitting yarn or thick pile yarn, or core-spun yarn with filament as the core. Nevertheless, the vortex spinning, which also feeds the sliver into the yarn directly, has the conditions and possibilities to realize the production of a fully automated continuous production line. Due to the cancellation of the roving frame, the spinning frame and the automatic winder, the floor space, labor and investment are reduced, so it has its unique advantages, and will further replace the ring yarn and air-flow yarn in the field of knitting yarn. Therefore, it is necessary to continue to carry out research and improvement to overcome its disadvantages and limitations and make it a new spinning method with characteristics.
