Cotton Fibers must be separated from the seed before they can be spun to yarn and used to manufacture textile goods. It is believed that the first mechanical gin (Churka) was a roller gin consisting of two rollers turning together by means of a hand crank. The Churka gin was most efficient when handling naked seeded varieties with loosely attached fibers. Early American settlers found that the fuzzy seeded varieties (upland cotton) that yielded best in this country were difficult to gin on this machine. Consequently, the fiber was generally pulled from the seed by hand until Eli Whitney patented his cotton gin in 1794.

Whitney’s gin used spikes on a hand-driven cylinder to remove fibers from the seed. The spikes pulled lint through slots that were too narrow for the seeds to pass. Whitney’s gin could process as much cotton as 100 people could gin by hand. Henry Ogden Holmes received a patent in 1796 for an improved gin that used saws rather than spikes to remove the fibers from the seed. The saws were spaced on a shaft to provide openings that allowed the clean seed to drop out the bottom. Holmes, invention made ginning a continuous flow process rather than a batch process, and greatly increased capacity. The basic principles developed by Whitney and Holmes are used in modern gin stands, but there have been many improvements. This invention enabled cotton growers to rapidly expand production, and marked the beginning of the modern cotton industry.

When cotton was hand picked and carefully handled, the only machines needed in a ginning system were a gin stand and a baling press. Rougher hand harvesting methods and mechanical harvesters caused more moisture and foreign material (trash) to be mixed with the seed cotton. Thus, seed cotton cleaning, drying equipment and lint cleaners were developed to compensate for the faster harvesting methods. On average, gins must process about 1,400 and 1700 pounds of seed cotton to produce a 480- pound bale of lint for spindle picked and field- cleaned stripper harvesting methods, respectively.
