Vortex spinning
The properties of vortex spun yarn are similar to that of ordinary ring spun yarn, but the drawing speed is 20 times higher than that of ordinary ring spun yarn and 3 times higher than that of rotor spun yarn. The quality of vortex spun yarn is not as good as that of ordinary ring spun yarn, but the quality of vortex spun yarn is close to that of ordinary ring spun yarn when the output is increased at a higher speed.
MVS vortex spinning frame is a kind of spiral air produced by two rotary nozzles, which is used to push the feeding ripe bar around the fixed spindle to produce twist and form yarn. One end of the loose fiber is twisted around the lapped fiber to form true twist. Vortex yarn is similar to ordinary ring spun yarn. The yarn is divided into two parts, the inner core and the outer layer. The outer layer is wrapped fiber, and the fiber surrounds the inner core to form wrapped yarn, which makes the yarn very strong.
The vortex spinning system is fully automatic. The biggest advantage of the vortex spinning machine is to cancel all the twisting elements of the rotary machinery. It can reduce the maintenance cost of many machines, directly feed the ripe strips produced by the drawing frame, and cancel the roving process. However, there is a big problem in the vortex spinning process, which is the waste of raw materials in the spinning process, Fiber loss is about 5%. Although most of the fibers are short fibers, it will not affect the yarn quality.
Vortex spinning and rotor spinning have formed a competitive situation in the market, especially in the production of carded yarn in cotton spinning system, the output of vortex spinning is very high, the strength ratio is high when it is suitable for producing fine yarn, and the production cost can be reduced by half. It can be used in worsted wool spinning industry in the future.
Several common ways of yarn spinning
Soro spinning
Different from siro spinning, solospun can be directly used for weaving without sizing. Solospun is another improvement of ring spinning technology. In addition to solospun technology, there are many grooves on the surface of the lower roller which are installed on the spinning frame to output the fiber bundles to several fine slots from the front. The fibers on these grooves are combined on one yarn, and the resultant yarn is composed of multiple single yarns. Compared with Siro spinning, siro spinning has only two grooves. The advantages of solo spinning are high yarn strength, good friction resistance and less hairiness.
Solo spinning can also replace double strand yarn to be processed on warp knitting machine. Solo spinning mechanism is simple and easy to install and remove. One erector can install 1000 spindle solo spinning device in three hours. The machine has many functions and strong adaptability. The Soro spinning mechanism can be removed. The machine can continue to operate in one minute. The production cost of Soro spinning is also low. The roller can be replaced every six months. Only the roller needs to be replaced, and no tools are needed.
Soro spinning has great economic advantages in wool spinning, such as processing a wide range of wool fibers; High output and spinning efficiency; The twisting system is canceled and combined processing is carried out; The winding output and efficiency are improved; Coarse wool fiber can be used as much as possible; Compared with double strand production, the output time is shorter.
Solow spinning can produce fine count yarn for weaving light weight fabrics. Solow spinning can be used to produce higher quality wool clothing and a wider range of wool products.
