Zhejiang Spinning Industry Equipment Retrofit Saves Cost And Develops New Products.

< p > to develop all kinds of new yarns, we must increase input in the application of new technologies and new technologies. We should set up a professional R & D team and corresponding testing and analysis methods according to local conditions, so as to make the product development go to a scientific and market-oriented orbit and enhance the stamina and vitality of product development.

< p > according to the relevant statistics, Zhejiang now has nearly 10 million ingot spinning capacity, and the new technology of rotor spinning and jet vortex spinning is in the leading position in China.

But from the analysis of yarn structure, ring spinning lines still dominate the market.

Every year, Zhejiang produces over 1 million 200 thousand tons of all kinds of ring spun yarn, and it needs more than 1 million 500 thousand tons of various spinning materials (including all kinds of new spinning materials).

At the same time, Zhejiang natural < a target= "_blank" href= "http://www.91se91.com/" > textile < /a > raw material resources (cotton, wool, etc.) shortage. At present, 90% of cotton used by spinning enterprises in China depends on domestic and foreign supply.

The production of chemical fiber raw materials in Zhejiang is relatively large. It is the main production base of viscose fiber and polyester fiber (including staple fiber filament) in China.

Due to the rapid development of the textile industry needs a large number of labor force, and the labor shortage in Zhejiang Province, at present, more than 80% of the labor of spinning enterprises comes from the migrant workers in the central and western regions.

Although wages have increased year by year, the contradiction of recruitment is still very prominent.

< /p >

< p > based on the above two reasons, the processing cost of Zhejiang spinning enterprises is much higher than that of the central and western regions.

The current labor costs increase year by year and the prices of raw materials, especially cotton, remain high, so that the "a href=" http://www.91se91.com/news/ "spinning enterprise" /a is facing enormous pressure.

Therefore, how to reduce labor employment and get rid of dependence on cotton has become the two difficult problem for Zhejiang spinning enterprises to survive and develop.

According to the survey, in the face of the current grim situation, many leaders of Zhejiang's spinning enterprises do not shrink from difficulties. Instead, they actively adopt the strategy of relying on scientific and technological innovation and product innovation to enhance their ability to resist risks and enable enterprises to continue to develop in a sustainable way.

< /p >

< p > relying on scientific and technological innovation, many spinning enterprises have speeded up the application of new technology and new equipment, vigorously developed full-automatic and semi-automatic rotor spinning and the most advanced jet spinning and vortex spinning technology in the world.

Owing to the shortening of spinning process and automation of equipment, intellectualization and high production efficiency, the labor utilization of spinning enterprises has been greatly reduced.

According to the analysis, the production of the new spinning equipment has only 20~25 people per 10000 ingots, which is about half of that of the current ring spinning.

< /p >

< p > in the active use of new spinning equipment, Zhejiang spinning enterprises are also accelerating the upgrading and pformation of traditional ring spinning equipment.

In addition to the common use of blowing carding machine and automatic winding machine, in recent years, Zhejiang spinning enterprises also actively adopt the automatic doffing spinning machine and the corresponding pallet type automatic winding machine, so that the employment of the two processes of spinning and winding in the ring spinning is significantly reduced.

According to the analysis of the actual employment situation of the enterprises that have used these two advanced equipment, the employment of each 10000 spindles can be reduced to less than 50, which is more than half of that of the traditional spinning process.

At present, compact spinning and siro spinning technology are expanding and applying in Zhejiang ring spinning enterprises. < p >

Practice has proved that they can significantly reduce hairiness, improve evenness and enhance yarn strength of ring spinning yarns.

In particular, the experience gained by Changshan textile company in the use of compact spinning technology in the production of colored yarn is of positive significance to the colored spinning enterprises.

In addition, the use of composite < a href= 'http://www.91se91.com > spinning technology > /a > to develop new yarns has also achieved certain achievements.

For example, the development of segmented yarn with composite spinning technology has been applied in many colored spinning enterprises. The core spun yarn of composite spinning technology has developed from conventional spandex core spun yarn to non elastic silk and metal wire as core yarn, and many kinds of core spun yarn with non cotton raw materials are developed.

< /p >

< p > Chun Jiang Textile Group has developed two kinds of core spun yarn: Cotton Bag < a href= "http://www.91se91.com" > polyester filament > /a > metal filament. At present, it has been mass produced.

The cotton bag polyester filament is the upgrading and replacement product of the conventional polyester cotton blended yarn. It overcomes the shortcomings of the conventional polyester cotton fabric which makes the polyester fiber exposed on the yarn surface and affects the wearability.

The polyester yarn of cotton wrapped polyester filament is located in the core part, which is mainly cotton, and greatly improves the wearability on the basis of keeping the polyester cotton product crisp and fast drying performance.

The cotton wrapped stainless steel filament is a core spun yarn with electromagnetic shielding properties. It uses a stainless steel filament with a diameter of 23 microns as the core wire to wrap the combed cotton, forming a good core sheath structure.

Among them, combed cotton and stainless steel filament ratio is two kinds of 81/19 and 70/30, the spinning number is 18.5tex, the shielding effectiveness of the fabric is tested to reach above 99.5%, shielding effectiveness is greater than 23dB, and the effect is good.

< /p >

Besides, P also developed the "cotton wrapped polyester filament core sewing thread" in 2012.

It uses high strength polyester filament as core filament to produce high quality long staple cotton, adopts two step dyeing process after dyed polyester filament and dyed cotton fiber, and uses antistatic agent in the finishing process of < a href= "http://www.91se91.com" > sewing thread < /a > to ensure that the finished sewing thread has high strength, uniform dyeing and good antistatic effect, and can improve the production efficiency of high-speed sewing.

< /p >

< p > Hongyu textile company also uses the technology of siro spinning and core spun yarn to develop knitting yarn, so that the yarn has good effect of multiple colors and resilience, and has certain characteristics.

In short, it is a new trend in the development of ring spinning technology to apply various new spinning technologies on the ring spinning machines and develop new yarns with various new materials, so that three new technologies, new fibers and new yarns are organically combined.
