Gossypium
''Gossypium'' () is a genus of flowering plants in the tribe Gossypieae of the Malva, mallow family, Malvaceae, from which cotton is harvested. It is native to tropical and subtropical regions of the Old World, Old and New Worlds. There are about 50 ''Gossypium'' species, making it the largest genus in the tribe Gossypieae, and new species continue to be discovered. The name of the genus is derived from the Arabic word ''goz'', which refers to a soft substance. Cotton is the primary natural fibre used by humans today, amounting to about 80% of world natural fibre production. Where cotton is cultivated, it is a major oilseed crop and a main protein source for animal feed. Cotton is thus of great importance for agriculture, industry and trade, especially for tropical and subtropical countries in Africa, South America and Asia. Consequently, the genus ''Gossypium'' has long attracted the attention of scientists. The origin of the genus ''Gossypium'' is dated to around 5–10 ...

Gossypium Arboreum
''Gossypium arboreum'', commonly called tree cotton, is a species of cotton native to Indian subcontinent and other tropical and subtropical regions of the Old World. There is evidence of its cultivation as long ago as the Indus Valley Civilisation of the Indus River for the production of cotton textiles. The shrub was included in Linnaeus's ''Species Plantarum'' published in 1753. The holotype was also supplied by him, which is now in the Linnean Herbarium in the Swedish Museum of Natural History. Description Tree cotton is a shrub that grows to about one to two meters tall. Its branches, which are purple in color, are covered with fine hairs. Stipules are present at the leaf base and they are linear to lanceolate in shape and sometimes falcate (i.e. sickle-shaped). The leaves are attached to the stem by a 1.5 to 10 cm petiole. The blades are ovate to orbicular in shape and have five to seven lobes, making them superficially resemble a maple leaf. The lobes are linea ...

Gossypium Tomentosum
''Gossypium tomentosum'', commonly known as ''maʻo'', ''huluhulu'' or Hawaiian cotton, is a species of cotton plant that is endemic to the Hawaiian Islands. Genetic studies indicate that Hawaiian cotton is related to American species of ''Gossypium'', with its closest relative ''Gossypium hirsutum''. Description ''Maʻo'' is a shrub that reaches a height of 1.5–5 ft (0.46–1.52 m) and a diameter of 5–10 ft (1.5–3.0 m). The seed hairs (lint) are short and reddish brown, unsuitable for spinning or twisting into thread. Its flowers are bright yellow and have from 3-5 lobes that bloom in late summer to winter. Distribution Its ancestor may have come to the islands from the Americas as a seed on the wind or in the droppings of a bird, or as part of floating debris. Habitat It inhabits low shrublands at elevations from sea level to 120 m (390 ft). They can be found on all main Hawaiian islands besides Hawai'i, otherwise known as the Big Island.

Gossypium Hirsutum
''Gossypium hirsutum'', also known as upland cotton or Mexican cotton, is the most widely planted species of cotton in the world. Globally, about 90% of all cotton production is of cultivars derived from this species. In the United States, the world's largest exporter of cotton, it constitutes approximately 95% of all cotton production. It is native to Mexico, the West Indies, northern South America, Central America and possibly tropical Florida. Archeological evidence from the Tehuacan Valley in Mexico shows the cultivation of this species as long ago as 3,500 BC, although there is as yet no evidence as to exactly where it may have been first domesticated. This is the earliest evidence of cotton cultivation in the Americas found thus far. ''Gossypium hirsutum'' includes a number of varieties or cross-bred cultivars with varying fiber lengths and tolerances to a number of growing conditions. The longer length varieties are called "long staple upland" and the shorter length varie ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cotton
Cotton (), first recorded in ancient India, 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. The plant is a shrub native to tropical and subtropical regions around the world, including the Americas, Africa, Egypt and India. The greatest diversity of wild cotton species is found in Mexico, followed by Australia and Africa. Cotton was independently domesticated in the Old and New Worlds. The fiber is most often spun into yarn or thread and used to make a soft, breathable, and durable textile. The use of cotton for fabric is known to date to prehistoric times; fragments of cotton fabric dated to the fifth millennium BC have been found in the Indus Valley civilizat ...

Lint (material)
Lint is the common name for visible accumulations of textile fibers, hair and other materials, usually found on and around clothing. Certain materials used in the manufacture of clothing, such as cotton, linen, and wool, contain numerous, very short fibers bundled together. During the course of normal wear, these fibers may either detach or be jostled out of the weave of which they are part. This is the reason why heavily used articles, such as shirts and towels, become thin over time and why such particles accumulate in the lint screen of a clothes dryer. Because of their high surface area to weight ratio, static cling causes fibers that have detached from an article of clothing to continue to stick to one another and to that article or other surfaces with which they come in contact. Other small fibers or particles also accumulate with these clothing fibers, including human and animal hair and skin cells, plant fibers, and pollen, dust, and microorganisms.

Ginning
A cotton gin—meaning "cotton engine"—is a machine that quickly and easily separates cotton fibers from their seeds, enabling much greater productivity than manual cotton separation.. Reprinted by McGraw-Hill, New York and London, 1926 (); and by Lindsay Publications, Inc., Bradley, Illinois, (). The separated seeds may be used to grow more cotton or to produce cottonseed oil. Handheld roller gins had been used in the Indian subcontinent since at earliest 500 and then in other regions. The Indian worm-gear roller gin was invented sometime around the 16th century and has, according to Lakwete, remained virtually unchanged up to the present time. A modern mechanical cotton gin was created by English-American inventor Eli Whitney in 1793 and patented in 1794. Whitney's gin used a combination of a wire screen and small wire hooks to pull the cotton through, while brushes continuously removed the loose cotton lint to prevent jams. It revolutionized the cotton industry in the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
