What happens to cotton after it arrives at the cotton mills?

It Cleaned the cotton, and took out the seeds of the dirty cotton.

A cotton mill, the factory that houses spinning and weaving machinery

The cotton mill turns raw cotton into yarn or thread by cleaning the raw material, processing it and spinning it.

It goes through a carding machine that lines the fibers up in a single direction. They are then spun into thread, from there to yarn or the appropriate size for weaving.
