The need to find an easier and faster way to remove seeds from raw cotton lead to the invention of the Cotton Gin. It was a hand cranked machine with hooks to catch the cotton fibers and pull them through a mesh that was too small for the seeds to fit.
Increase in cotton production
Eli Whitney graduated from Yale in 1792 and left New England to take a job in Georgia. While working there he saw a need for a better way of removing the seeds from cotton. It wasn't long before he had developed the Cotton Gin.

Plantation owners used these Cotton Gins for separating the seeds from the cotton. Being able to produce cotton much faster lead to larger plantations. Larger plantations lead to larger production.
Before the Cotton Gin was invented it took one person 10 hours to separate the seeds from one pound of cotton. This had to be done by hand. One hand cranked Cotton Gin could separate 50 pounds of cotton in 10 hours.
This massive increase was met with a larger demand and larger export. The large increase made the United States the worlds largest cotton supplier which greatly helped Americas economy.
The down fall to the Cotton Gin was that it took more people to plant and harvest the cotton crops and that meant it greatly increased the buying of slaves.
