Focusing On The Mainstay Of The Industry -- Ring Spinning

In recent years, ring spinning technology continues to maintain a leading position in the development of many spinning technologies through continuous improvement and technological innovation.

In the new ring spinning technology, four new ring spinning technologies, such as compact spinning, siro spinning, low torque spinning and embedded spinning, have not only significantly improved the quality grade of ring spinning, but also widened the application field of ring spinning, which is the development and innovation of the ring spinning technology.

Low torque spinning: remarkable energy saving advantages

Low torque spinning is numerous.

Tao Xiaoming, a professor of Hong Kong Polytech University, one of the technical inventors, said that the low torque spinning technology was realized by adding a false twister device on the ring spinning frame.

The function of the false twister is to produce false twisting, which affects the fiber tension distribution in the spinning triangle area, thereby changing the shape and distribution of the fibers in the single yarn, making the fibers produce residual torque and balancing each other, achieving single yarn low twist, low twist and high strength.

Because of its small yarn torque and high strength, this technology can make traditional cotton yarn enter the high-grade knitting field which is hard to enter. The cotton knitted sweater made of cotton has little twisting, small yarn hairiness and unique cashmere handle, and the production process has obvious advantages of energy saving and energy saving.

Low torque spinning technology has been highly concerned by the industry since its formal launch, and many enterprises have begun to develop their own low torque technology.

In these enterprises, Shandong De Yuan cotton mill Co., Ltd. is at the forefront.

After more than a year's research and development, this company has officially introduced the denim fabric made of compact low torque yarn this year. The denim fabric has good cloth effect and feels extremely soft.

According to the company's relevant personnel, from the end of 2009, Deyuan cotton mill began to develop compact low torque yarn. Because of its characteristics of low twist, short torque and soft yarn, the advantages of its compact low torque yarn were fully reflected in the weaving of denim fabric. The denim fabric made of the compact low twist yarn has the advantages of small slant, easy cutting, soft handle and clear texture.

At present, low torque technology can not only combine with compact spinning technology, but also be combined with Siro spinning, Cero Phil spinning, core spun yarn and so on.

According to expert analysis, although this technology is still in its infancy, it is believed that with the improvement of the industry's attention to technology, there will be a large number of low torque devices in the coming years.

Embedded spinning: expanding application scope of raw materials

Though the improvement of traditional ring spinning technology has been made in recent years.

Among the enterprises in the field of application of embedded spinning technology in cotton spinning field, Jihua 3542 Textile Co., Ltd. is undoubtedly one of the most comprehensive enterprises applying this technology.

Li Hongsheng, assistant general manager of the company, said that embedded spinning is a new type of multi-functional spinning technology. The structure of the embedded spinning is similar to that of two filament and roving Siro Phil spinning, followed by siro spinning, two filaments on the outside, two roving inside the filament.

In spinning process, two roving frames are fed symmetrically from inside to normal draft, and two filaments are fed directly through the guide wire device symmetrically to the former roller, and two short fiber whiskers are first assembled with two filaments, and the short fibers of each side are pre twisted with filament and then gathered at a point for further twisting yarn.

There are essential differences between the internal and external pfer patterns of inlay spinning and traditional ring spinning.

The embedded yarn has high strength, good strip quality and less hairiness. It can be used to develop fine count yarn and some short spinnable raw materials with poor spinnability and multi colored yarn.

According to Li Hongsheng, Jihua 3542 has developed a series of products by using the strong advantages of embedded spinning, the advantages of four feed lines, the advantages of producing ultra short fibers and the advantages of spinning into strips.

Once these products came out, they were praised by customers.

Compact spinning: improving weaving efficiency

Compact spinning is the fastest spinning new technology in recent years.

According to relevant data, compact spinning has grown from 300 thousand in 2005 to 7 million 200 thousand at the end of 2010.

The rapid development of compact spinning is indispensable to its fine characteristics.

Compact spinning reduces the spinning triangle area, making yarn structure more compact, thereby reducing single yarn hairiness and improving strength.

Therefore, the application of compact spinning technology can improve weaving efficiency and improve cloth face style.

The excellent properties of compact spinning also promote the development of products.

After many years of compact spinning production, Jiangsu Dan Mao Textile Co., Ltd. has developed pure wool and spun silk.

Xu Rongfang, general manager of the company, said that through the development and application of compact spinning technology, the quality level of the company's products has been continuously improved, and compact spinning technology is also the foundation for the development of high value-added products in recent years.

Siro Spinning: greatly reducing Mao Yu

Compared with other new ring spinning technologies, siro spinning is no longer a new technology.

In the 90s of last century, siro spinning technology and products had caused a great sensation in the textile industry all over the world.

Since 1997, the Limited by Share Ltd of Shandong Dai Yin Textile Group, which used siro spinning technology, has installed siro spinning equipment on all ring spinning machines after more than 10 years of exploration, improvement and popularization.

According to Xie Songcai, deputy general manager of the company, siro spinning feed two roving yarns on the spinning frame to maintain a certain distance. After drafting, these two single yarn strands are output from the front roller, and a small twist is attached to the yarn on the single yarn due to the pmission of twist.
