Vortex spinning
Vortex spinning
The properties of vortex spinning yarn are similar to those of ordinary ring spinning yarn, but the extraction speed is 20 times higher than that of ordinary ring spinning yarn and 3 times that of rotor spinning. The quality of vortex yarn is not as good as that of ordinary ring-spun yarn, but when the output is increased at higher speeds, the quality of vortex yarn is close to that of ordinary ring-spun yarn.
The MVS vortex spinning machine uses two rotating nozzles to generate spiral gas, which is used to push the fed cooked sliver around the fixed spindle to produce twist and form yarn. One end of the loose fiber is twisted around the overlapping fiber to form a true twist. Vortex yarn is similar to ordinary ring-spun yarn. The yarn is divided into two parts, namely the inner core and the outer layer of the yarn. The outer layer is wrapped fiber, and the fibers surround the inner yarn core to form a wrapped yarn, making the yarn very strong.
The vortex spinning system is fully automatic and eliminates all rotating mechanical twisting elements. This is the biggest advantage of the vortex spinning machine. It can reduce many machine maintenance costs. It directly feeds the cooked sliver produced by the draw frame and eliminates the roving process. However, a major problem with vortex spinning is that it will cause a waste of raw materials during the spinning process. The fiber loss is about 5%. Although most of the lost fibers are short fibers, it will not affect the improvement of yarn quality.
Vortex spinning and rotor spinning have formed a competitive situation in the market, especially when the cotton spinning system produces medium-count carded yarn. The output of vortex spinning is very high, which is suitable for the production of fine-count yarns with relatively high strength, and the production cost can be halved. It can be used in the combed wool spinning industry in the future. AbVIP0d
