Cotton is a major fibre crop of global importance and has high commercial value. It is grown commercially in the temperate and tropical regions of more than 70 countries. Specific areas of production include countries such as China, USA, India, Pakistan, Uzbekistan, Turkey, Australia, Greece, Brazil, Egypt etc., where climatic conditions suit the natural growth requirements of cotton. These include periods of hot and dry weather and adequate moisture obtained through irrigation. Cotton is harvested as ‘seed cotton’ which is then ‘ginned’ to separate the seed and lint. The long ‘lint’ fibres are further processed by spinning to produce yarn which is knitted or woven into fabrics.
