A cotton gin – meaning "cotton engine" – is a machine that quickly and easily separates cotton fibers from their seeds, enabling much greater productivity than manual cotton separation.
Although cultivated since antiquity, it was the invention of the cotton gin that lowered the cost of production that led to its widespread use, and it is the most widely used natural fiber cloth in clothing today.

Cotton fibers are produced in the seed pods ("bolls") of the cotton plant where the fibers ("lint") in the bolls are tightly interwoven with seeds.
These fibres are the more commercially interesting part of the plant and they are separated from the seed by a process called ginning.

While Whitney's gin facilitated the cleaning of seeds from short-staple cotton, it damaged the fibers of (extra-long staple) cotton (Gossypium barbadense).
The invention of the cotton gin by the end of the 18th century utterly changed the production of cotton as a commodity crop.

Cotton module builder

module buildermodules
In modern cotton production, cotton arrives at industrial cotton gins either in trailers, in compressed rectangular "modules" weighing up to 10 metric tons each or in polyethylene wrapped round modules similar to a bale of hay produced during the picking process by the most recent generation of cotton pickers.
The modules are later loaded onto trucks and transported to a cotton gin for processing.
