The cotton industry in the United States has faced many problems dating back to the first written report of cotton in the Virginia colonies in 1607 when the lint and seed was separated by hand. The invention of the toothed cotton gin by VVhitney in 1795 and improvements by Holmes in 1796 were the developraents needed to revolutionize the cotton industry. After the development of the cotton gin, production of upland cotton increased rapidly, reshaping the social and economic history of the United States. The cotton economy remained strong until World War II except for the normal cyclic conditions due to political and economic environment. The development and growth of the synthethic fiber industry after World War II caused a treraendous reduction in demand for cotton in the raarket place. Promotion and development work by the cotton industry has helped recapture some of the market.

Cotton dust is presently one of the primary concems of the cotton industry. Regulations to control cotton dust are presently being implemented. The degree of control varies within the specific area of cotton processing. Through research and development the industry is continually searching for technology to meet these proposed standards. Although the regulations specifically mention cotton gins, oil mills, and textile mills, this does not mean that controls and research will or should be confined to these areas. New technology in areas of production and harvesting can have a tremendous impact in reducing contamination before processing has begun.
