Major uses of cotton fibres. Source: Adapted from: Cotton Facts, International Cotton Advisory Committee (ICAC), 2003. The major end uses for cotton fibre include wearing apparel, home furnishings, and other industrial uses (such as medical supplies). The cotton fibre is made primarily into yearns and threads for use in the textile and apparel sectors (wearing apparel would account for approximately 60% of cotton consumption).
China, United States, India, Pakistan, Uzbekistan and West Africa account for over 75% of global production. Cotton represents nearly half the fibre used to make clothes and other textiles worldwide, with much of the rest coming from synthetic products (as highlighted in the 2003 WWF report Thirsty Crops).
