What is vortex spinning?

Vortex spinning is a new spinning method that uses a stationary vortex spinning tube instead of a high-speed rotating spinning cup for spinning.

Advantages of vortex spinning:
1. Fast speed and high output is equivalent to 4-5 times of ring yarn. The output of a vortex spinning head is equivalent to the output of 2.08 air spinning heads or 8.5 ring spindles.
2, the process is short, the production rate is high. The vortex spinning is directly spun into the cheese yarn by the fiber sliver, so like other new spinning, the two processes of roving and winding can be omitted. Since the vortex spinning end rate is very low, the return loss is small, and the production rate is as high as 99% or more.
3, suitable for spinning, it is suitable to do the napped products. The yarn structure is relatively bulky, so its dyeability, suction property and air permeability are better, and the pilling resistance and wear resistance of the yarn are also better. The range of the yarn count is limited to medium and low yarns, and it is suitable to be a cashmere product.
4, simple operation, convenient joints Because the vortex tube is stationary, there is no high-speed rotating parts, so the joint is very convenient and simple, no need to clean after breaking, improve the working environment. Because there is no high-speed rotating component in vortex spinning, there is no high-speed bearing lubrication problem, less loss, low noise and convenient maintenance.
Limitations of vortex spinning:
1. The vortex spinning has low strength and instability, restricting its development to the fine yarn field, and its competitiveness in the fine yarn field is still not strong.
2. The vortex spinning still cannot solve the problem of the yarn arm formed when the free end yarn tail rotates at high speed in the vortex tube, resulting in large centrifugal force and tension. Therefore, the spinning speed is not likely to have a breakthrough.
3, vortex spinning has its unique advantages, in the field of knitting yarn will further replace ring and air yarn. However, it is necessary to continue research and improvement, overcome its disadvantages and limitations, and make it a new type of spinning method with characteristics.
