The Development Of High-End Rotor Spinning Machines Is Imminent.

< p > now, some spinning machinery factories in China have developed and developed the domestic rotor spinning machine on the basis of absorbing foreign advanced technology experience, basically getting rid of the old model of rotor spinning machine.

At present, the rotor speed of the domestic semi-automatic rotor spinning machine is about 70 thousand ~9 / min, with a maximum speed of about 120 thousand rpm. The semi-automatic rotor spinning machine can produce 30 or less rotor yarn, and the technology development has been greatly improved.

In addition to Jingwei Textile Machinery Factory, we also develop new rotor spinning machines in Zhejiang except for Jingwei Textile Machinery Factory, such as the Titan spinning machine, Japan hair spinning machine, Sichuan Chuan Jiang spinning machinery company, Shanxi Shanghai Jin spinning machine, Jinzhong textile machinery, etc., but the speed of the rotor spinning can only reach 120 thousand revolutions per minute. Although the machine has equipped with electronic cleaning and waxing devices, it is still a semi-automatic rotor spinning machine.

This should be the second generation rotor spinning machine of our country.

< p > foreign high-end semi-automatic rotor spinning machines, such as Swiss Lida BT series rotor spinning machine are economical.

The BT923 semi-automatic rotor spinning machine has the advantages of high speed, good spinning quality and strong adaptability of product varieties. It has a good performance price ratio and the speed is 110 thousand revolutions / min.

The BD416 semi-automatic rotor spinning machine in Germany has good cost performance and is suitable for China and the three world countries.

< p > China should pay attention to the development of the high-end semi-automatic rotor spinning machine while developing the automatic rotor spinning machine.

Over the years, some semi-automatic and fully automatic rotor spinning machines have been introduced from abroad. Through use, they have improved the understanding and management experience of the imported semi-automatic and automatic rotor spinning machines. On the other hand, the application process is also a process of digestion and absorption. This has made theoretical and technical preparations for the development of China's < a href= "//www.sjfzxm.com/news/index_f.asp" > rotor spinning machine < /a >.

< /p >

< p > China's < a href= "//www.sjfzxm.com/news/index_f.asp > > textile industry < /a >" 12th Five-Year "plan for science and technology development plan clearly stipulates that we should develop our country from the world textile power to the world textile power in the year of 5~10.

It is mainly reflected in < a href= "//www.sjfzxm.com/news/index_f.asp > textile > /a > production of short process, high speed, high yield, high quality, high automation, continuity, modularization, production management, high technology, less labor, emission reduction and consumption, etc., the development of high-grade rotor spinning is to follow the above goals and principles.

In order to achieve this goal, on the one hand, the high grade rotor spinning machine can be used to produce low grade cotton for producing high quality yarn; on the other hand, it can match the combed ring yarn with the combed noil of long staple cotton to produce high quality cotton yarn, so as to realize the purpose of comprehensive utilization of raw cotton.

The high-end automatic and semi-automatic rotor spinning machine is the third generation rotor spinning machine of our country.

< /p >

< p > the development of high-grade rotor spinning machines should be synchronized with the development of combed ring spinning, and the establishment of short process rotor spinning line is a good way to reduce labor consumption, reduce consumption and reduce emissions in spinning mills.

But at present, some large spinning factories in China (200 thousand ring and above) all produce combed yarn, but the factory does not have a rotor spinning machine.

Long staple cotton is a valuable raw cotton, which is a waste of valuable raw cotton.

In order to further improve the quality of combed yarn, enhance the value of combed yarn and save long staple cotton, the developed countries have deliberately increased the amount of combed cotton to 21% and above. Using these noil on rotor spinning machines to produce a certain number of rotor spun yarns has not only economic benefits, but also a good way to save cotton.

This shows that the development of rotor spinning in China has great potential to be excavated.

< /p >

In the development of high performance rotor spinning machines in China, we should put the high performance spinning machine in the first place and produce high-performance spinning machines abroad as early as possible in P.

When developing high tech rotor spinning machines in China, we should focus on increasing the production of medium and fine top grade knitted and woven yarns with high quality rotor spinning. In order to make the development of rotor spinning in China enter a new stage, we must put the high performance spinning machine in the first place.
