What is eddy spinning? Eddy current spinning is a new spinning method which uses a fixed eddy current spinning tube instead of a spinning cup with high speed.

Advantages of vortex spinning:

1, fast speed, high yield: equivalent to 4_5 times of ring spindle yarn, the output of a vortex spinning head, equivalent to 2.08 air flow spinning head or 8.5 ring spindle output.

2. Short process flow and high production rate: eddy current spinning is directly spun from fiber slivers into bobbin yarn, so like other new spinning, two processes of roving and winding can be omitted. Because the end breaking rate of eddy spinning is very low and the loss of return flower is less, the production rate is more than 99%.

3, suitable for spinning strong, appropriate to make velvet products: yarn structure is relatively bulky, so its dyeing, slurry absorption, air permeability are better, yarn pilling resistance and wear resistance is also better. Yarn count range, only medium and low - count yarn, appropriate to make fleece products.

4, simple operation, convenient joint: because the vortex tube is stationary, no high-speed rotating parts, so the joint is very convenient and simple, no need to clean after the broken end, improve the working environment. Because swirl spinning has no high-speed rotating parts, there is no high-speed bearing lubrication problem, less consumption, low noise and easy maintenance.

Limitations of vortex spinning:

1, the strength of eddy spinning is low and unstable, which limits its development to the field of fine yarn, and its competitiveness in the field of fine yarn is not strong.

2. Vortex spinning still fails to solve the problem of yarn arm formed when the free-end yarn tail rotates at high speed in the vortex tube, which leads to large centrifugal force and tension. Therefore, its spinning speed is unlikely to have a breakthrough progress.

3, vortex spinning has its unique advantages, in the field of knitting yarn will further replace ring spindle yarn and air flow yarn. However, it is necessary to continue to study and improve the spinning method to overcome its disadvantages and limitations and make it a new spinning method with its own characteristics.
