Cotton is a soft, fluffy staple fiber that grows in a boll, or genus Gossipier in the mallow family Malvaceae. The fiber is almost pure cellulose. Under natural conditions, the cotton bolls will increase the dispersal of the seeds. (Wikipedia)
Cotton has different kinds and different qualities, each suitable for different purposes. The long lint fibers are used for yarn, thread, and cotton fabric. Bedding and clothing items are common products.
Cotton is divided into four major groups (by quality):
- Sea Island Cotton: This one is the best cotton in the world. It has the longest staple (2- ¼”; the maximum length by nature). It is found in South Carolina, Georgia, and Florida and many islands of these states.
- .Pima Cotton: The second longest staple (1- 3/4”). It’s found in Peru and Egypt, and the Southwestern U.S
- U. S Cotton: Other than Sea Island cotton, this type of cotton is found in the United States, too. The staple length may reach 1- ½”.
- Asian Cotton: It is in Asia, Japan, China, Pakistan, and India. The staple isn’t longer than 1- 1/8”.
The thickness of cotton is important too, because the longest and finest cotton is used to make high-quality fabrics
