Overview
Cotton is a soft, fluffy staple fiber that grows in a boll, or protective case, around the seeds of the cotton plants of the genus Gossypium in the mallow family Malvaceae. The fiber is almost pure cellulose, and can contain minor percentages of waxes, fats, pectins, and water. Under natural conditions, the cotton bolls will increase the dispersal of the seeds.
Types
There are four commercially grown species of cotton, all domesticated in antiquity:
• Gossypium hirsutum – upland cotton, native to Central America, Mexico, the Caribbean and southern Florida (90% of world production)
• Gossypium barbadense – known as extra-long staple cotton, native to tropical South America (8% of world production)
Etymology
The word "cotton" has Arabic origins, derived from the Arabic word قطن (qutn or qutun). This was the usual word for cotton in medieval Arabic.

The word entered the Romance languages in the mid-12th century, and English a century later. Cotton fabric was known to the ancient Romans as an import but cotton was rare in the Romance-speaking lands until …

Competition from natural fibers
High water and pesticide use in cotton cultivation has prompted sustainability concerns and created a market for natural fiber alternatives. Other cellulose fibers, such as hemp, are seen as more sustainable options because of higher yields per acre with less water and pesticide use than cotton. Cellulose fiber alternatives have similar characteristics but are not perfect substitutes for cotton textiles with differences in properties like tensile strength and thermal regulation.
