Detailed explanation-1: -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.
Detailed explanation-2: -In 1794, U.S.-born inventor Eli Whitney (1765-1825) patented the cotton gin, a machine that revolutionized the production of cotton by greatly speeding up the process of removing seeds from cotton fiber. By the mid-19th century, cotton had become America’s leading export.
Detailed explanation-3: -While Eli Whitney is best remembered as the inventor of the cotton gin, he was also the father of the mass production method. In 1798, he figured out how to manufacture muskets by machine so that the parts were interchangeable. It was as a manufacturer of muskets that Whitney finally became rich. He died in 1825.
Detailed explanation-4: -Before the cotton gin, cotton was a troublesome crop. Its fiber could only be separated from the sticky, embedded seeds by hand, a grueling and exhausting process. This changed dramatically, of course, with the advent of the cotton gin. Suddenly cotton became a lucrative crop and a major export for the South.
