Nature Fiber - Cotton 棉花
The cotton fiber grows on the seed of a variety of plants of the genus Gossypium. Of the 4 cotton species cultivated for fiber, the most important are G. hirsutum, which originated in Mexico and produces 90% of the world’s cotton ; and G. barbadense, of Peruvian origin.
An estimated 60% of cotton fiber is used as yarn and threads in a wide range of clothing, most notably in shirts, t-shirts and jeans, but also in coats, jackets, underwear and foundation garments.
Cotton is also used to make home furnishing, such as draperies, bedspread and window blinds, and is the most commonly used fiber in sheets, pillowcases, towels and washcloths.
It is made into specialty material suitable for a great variety of application : fire-proof apparel, cotton wool, compresses, gauze bandages, sanitary towels and cotton swabs. Industrial products containing cotton include bookbindings, industrial thread and tarpaulins.
Cultivated in around 80 countries, cotton is one of the world’s most widely produced crops and uses about 2.5% of the world’s arable land area. The world produces around 25 million tones of cotton every year. Six countries : China, Brazil, India, Pakistan, the USA, and Uzbekistan, account for more than 80% of total production.
