Introduction of rotor spinning

Airflow spinning was firstly patented by Bertelsen in Denmark in 1937, and then continuously researched by scholars from France, Czechoslovakia and other countries. China began to research from 1958, 1967 began to be gradually applied to industrial production. since the 70's, rotor spinning technology and mechanical equipment development is rapid, the application is more and more extensive. There are many manufacturers in the world to produce a variety of models, about more than 300 million head of rotor spinning equipment, applications throughout the five continents dozens of countries. Suitable raw materials for spinning from cotton and cotton chemical fibers to wool and wool chemical fibers, both pure spinning and blending. Spinning number range up to 190 ~ 13 (3 ~ 45 count), the rotor speed has been increased from 30,000 rpm to 50,000 ~ 60,000 rpm, and even as high as 70,000 rpm or more. Rotor spinning machine has been widely used in spinning device with debris removal device, semi-automatic and fully automatic cleaning, jointing and yarn dropping device and some other auxiliary devices. Rotor spinning before and after the process of technology and equipment supporting the continuous completion.
