Ring spinning is a continuous process, unlike mule spinning which uses an intermittent action.

Traditionally ring frames could only be used for the ...

The most favoured cottons are the ones with the longest staple as they can be spun into the finest thread. Sea Island and Egyptian are two of these.
Cotton-spinning machinery is machines which process (or spin) prepared cotton roving into workable yarn or thread. [1] Such machinery can be dated back centuries. During the 18th and 19th centuries, as part of the Industrial Revolution cotton-spinning machinery was developed to bring mass production to the cotton industry.
The average age of installed rotors is much lower than that of spindles and as rotors are between 7 and 10 times more productive they are responsible for 20% of the cotton spun worldwide. [89] Modern cotton mills are increasingly automated. One large mill in Virginia in the United States employs 140 workers in 2013 to produce an output that ...
