With the development and social progress of science and technology, human requirements for textiles continues to increase, and therefore the yarn quality requirements also a higher standard. The development of human spinning technology has gone through a long process, the emergence of ring spinning method, the spinning technology to advance to a new stage, however, due to the limitations yarn ring spinning mechanism by spinning speed and further substantial increase in production can not, moreover, ring system in the process, there are still many irrational aspects. Therefore, the principle of opening up new spinning, spinning new research methods to improve yarn production, quality and development of new varieties of yarn has become one of the directions people efforts.

Development of new technologies has not stopped spinning, from the 20th century, 50 years, it has emerged as a distinct ring mechanism and yarn spinning, air-jet spinning, electrostatic spinning, friction spinning, spinning parallel vortex spinning, self-twist spinning and other new spinning technology. In recent years, there was a jet vortex spinning (MVS), the emergence of these new methods and techniques of spinning, breaking the traditional yarn spinning mechanism, so that enhance the spinning speed of the package is increased as possible, so labor productivity greatly improved varieties greatly increased, thus promoting the development of spinning technology.

Spinning way a wide range of different new spinning methods have different yarn spinning mechanism and the mechanism of its (mainly twisting characteristics), its yarn structure, yarn properties and further applications are also quite different. It can be divided into non-twisting new ring spinning technology (open-end spinning method, the non-open-end spinning method) and a new spinning method into two categories based on ring twisting (twisting spindle) of.

For non-open-end spinning, such as air-jet spinning, self-twist, such as spinning, the fiber sliver in the spinning process is completely continuous. So, it is usually caused by feeding the fiber ring with a similar roller drafting device to complete the fiber roller drafting process has strong controls, so that the fibers are arranged more straight, parallel to a yarn quality to provide a guarantee. In addition, non-open-end spinning, the fibers are twisted at both ends are subject to mechanical control, so that the yarn tight and high, straight and parallel fiber yarn is good in the process.

For open-end spinning, such as spinning, friction spinning, electrostatic spinning, etc., since the fiber yarn by twisting the true manner, and therefore, it must ensure that produce a breaking point (the free end) in the course of transmission fiber, add to meet the requirements of real twist. Usually before twisting off the continuous fiber bundle, normally open in its axial direction. Often using fiber opening roller decomposition, in order to ensure separation of the fiber to form a free end. Open-end spinning method has great influence on the strength of yarn.

For new spinning technology is based on twisted ring, use yarn ring mechanism, the mechanism by changing the spinning machine, feeding methods and strengthen control of fiber triangle to optimize ring technology, the yarn performance greatly improved, or given a new structure of the yarn, the fabric has a new style. Spinning class technologies include spinning, spin coating, core-spun, Siro spinning, Sailuofeier spinning, spinning Solomon, low torque spinning, compact spinning and the like.

It features a variety of different methods

Different methods have different spinning spinning spinning mechanism and a different structure, as well as the applicability of different fibers and different yarn structure and properties.

Rotor Spinning: rotor yarn is generally believed that a three-tier structure: the central area more closely; the outer structure is relatively loose; also outsource some surface wound fibers. Rotor yarn fibers form except a few typical spiral shape, most were hooked, playing volume, complex shape wrapped around a combination like. Spinning spinning fibers suitable to determine the main consideration of fiber length. Fiber length and rotor diameter relative should apply. In the case of appropriate length, can be spun fibers are cotton, wool, silk, linen, chemical fiber and blended. Back various flowers, scraps, and even waste textile raw materials can be used, but if the fibers are too short, the difference between the fibers hold cooperation with, yarn quality will be reduced.

Jet spinning: Jet wrapped yarn is a typical structure in which the center is less twist untwisted core fibers, the surface is wrapped (bundled) fibers. This structure and the fiber spinning process of claim requires a certain length, thus spinning T / C, pure polyester and so it is always suitable for spinning raw materials, not spinning cotton; In recent years, a variety of cotton cellulose fibers widely used in air-jet spinning, which has become the most suitable fibers, such as viscose, modal and other, mainly due to addition of suitable length, these fibers generally soft finished, just to improve product feel hard jet and yarn defects, therefore, viscose cellulose fibers became represented by the most suitable air-jet spinning spun fibers.

MVS spinning: spinning vortex jet stream is completed by decomposition, condensation, stripping, twisting and so on, with a clear open-end spinning characteristics. It formed the basis for the end of the free end of the yarn. MVS yarn fibers from the portion of the core and an outer layer of twisted fibers, fibrous outer spiral twisting features significantly different from the characteristics of the jet pack wrapped spinning. More fiber twisting degree of jet vortex spinning, staple fiber such as cotton can be spun, but the practice has proved that the effect is still not as good as spun cotton and chemical fiber blend. The latest research shows that the best jet vortex spinning a fiber length of about 32mm.

Friction spinning: spinning due to friction during operation of the fiber, there is a change in the direction of a larger angle, so the fibers stretched by a greater impact, so the fibers in yarn form a more disordered, fold, roll wrapped around irregular shape of fibers hook accounted for 70% to 80% in the yarn, which belongs to the end of the first spiral shape without defects fibers less than 10%. Friction spinning fiber spinning its proper degree of broader fiber length between 10mm ~ 150mm, can be cotton, wool, silk, hemp, chemical fiber. The maximum length is suitable for spinning spinning method.

Since spinning twist: double twist yarn from stocks, an additional requirement of a twist on a twisting or twist twister since the strands can be used for weaving; self-twist strands twist irregularity than not ring strands large uniform rate of 3% to 4%, a strong 15% to 20% strength irregularity by 2% to 3%, the elongation at break is also high. Suitable spun fibers requires a certain length, usually wool (60mm or more), long fiber (65 ~ 76mm above), expanded acrylic (80mm or more).

Vortex spinning (Traditional): It is worth noting that traditional jet vortex spinning and vortex spinning are two different spinning methods, it is completely open-end spinning. Its very fiber yarn vortex disorders, a large number of closed surface of the fiber, it is appropriate to start its velvet fabric of reason. By limiting the vortex tube diameter (14mm ~ 16mm), only spinning vortex spinning cotton fibers, including cotton, chemical fiber, spinning some short (down) fiber, acrylic fiber good (pile fabric) and other effects.

New technologies have obvious advantages. Use the mechanism of ring yarn spinning technology is based on the new ring twisting, spinning machine by changing the mechanism, feeding methods and strengthen control triangle fiber technology to optimize the ring, make yarn greatly improved performance, or given a new structure of the yarn, the fabric has a new style. Spinning class technologies include spinning, spin coating, core-spun, Siro spinning, Phil Siro spinning, spinning Solomon, low torque spinning, compact spinning and the like.

Spinning the front roller or rollers near the front plus control elements, it strengthened the fiber of control, so that should be more closely aligned strip, greatly reducing the traditional spinning in twisting triangle strip width to be, or Save or eliminate the twisting triangle area is conducive to the sliver of fiber volume to reliably twisted yarn, so that a more substantial reduction in hairiness, but also conducive to the suction when twisted fibers wound around again straighten opportunity to eliminate yarn hairiness, improve yarn strength.

Sirospun two roving is fed at a constant pitch spinning drafting system, while being drawn, formed to maintain a certain distance between two fiber sliver after the front roller grip points out, this article shall be due plus two twist the role of convergence, twisted synthetic strands, and then by the guide wire, bead onto the bobbin winding become Siro yarn.

Phil Siro spinning is developed from Sirospun, that Siro spinning, substituted with a filament which a roving, is greater than the spacing between the two roving Sirospun pitch. Phil Siro yarn is greater than the breaking strength of short fiber twine and Siro yarn, yarn elongation at break than the large, less hairiness. Replaced with a synthetic filament yarn, can reduce costs, but also improve the yarn number.

Solomon is spinning spinning beneath the front roller surface has many grooves plus a split roller or plastic clips, grooves or use plastic clips to the front roller output shall be divided into a plurality of narrow strips, since the transfer twist, these narrow bar with a small amount of twist, after twisting then be merged to form a similar strands (cable yarn) yarn of Solomon, so Solomon spun in turn called cable-type spinning.

Advances in materials and textile fibers spinning technology to improve the yield and quality of textiles. Development of new yarn material should new fiber applications and two new spinning technology aspects of organic combination, in order to develop excellent features, welcomed by the market of the product.
