Cotton
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. 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 civilization, as well as fabric remnants dated bac ...

Staple Fiber
A staple fiber is a textile fiber of discrete length. The opposite is a filament fiber, which comes in continuous lengths. Staple length is a characteristic fiber length of a sample of staple fibers. It is an essential criterion in yarn spinning aids in cohesion and twisting. Compared to synthetic fibers, natural fibers tend to have different and shorter lengths. The quality of natural fibers like cotton is categorized on staple length such as short, medium, long-staple and, extra long. Gossypium barbadense, one of several cotton species, produces extra-long staple fibers. The staple fibers may be obtained from natural and synthetic sources. In the case of synthetics and blends, the filament yarns are cut to a predetermined length (staple length). ''The filament is <1 mm in maximum cross section (i.e., diameter, in most cases). A filament can be compared ... Manufactured fibers are produced either as continuous infinite length filaments or cut staple of desired length value.< ...

Gossypium Barbadense
''Gossypium barbadense'' (''gos-SIP-pee-um bar-ba-DEN-see'') is one of several species of cotton. It is in the mallow family. It has been cultivated since antiquity, but has been especially prized since a form with particularly long fibers was developed in the 1800s. Other names associated with this species include Sea Island, Egyptian, Pima, and extra-long staple (ELS) cotton. The species is a tropical, frost-sensitive perennial that produces yellow flowers and has black seeds. It grows as a bush or small tree and yields cotton with unusually long, silky fibers. ''G. barbadense'' originated in southwest Ecuador and northwest Peru. It is now cultivated around the world, including China, Egypt, Sudan, India, Australia, Peru, Israel, the southwestern United States, Tajikistan, Turkmenistan, and Uzbekistan. It accounts for about 5% of the world's cotton production. Taxonomy and etymology Linnaeus is given credit for describing ''Gossypium barbadense'' ("cotton encountered in ...

CSIRO ScienceImage 10736 Manually Decontaminating Cotton Before Processing At An Indian Spinning Mill
The Commonwealth Scientific and Industrial Research Organisation (CSIRO) is an Australian Government agency responsible for scientific research. CSIRO works with leading organisations around the world. From its headquarters in Canberra, CSIRO maintains more than 50 sites across Australia and in France, Chile and the United States, employing about 5,500 people. Federally funded scientific research began in Australia years ago. The Advisory Council of Science and Industry was established in 1916 but was hampered by insufficient available finance. In 1926 the research effort was reinvigorated by establishment of the Council for Scientific and Industrial Research (CSIR), which strengthened national science leadership and increased research funding. CSIR grew rapidly and achieved significant early successes. In 1949, further legislated changes included renaming the organisation as CSIRO. Notable developments by CSIRO have included the invention of atomic absorption spectroscopy, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Classical Arabic
Classical Arabic ( ar, links=no, ٱلْعَرَبِيَّةُ ٱلْفُصْحَىٰ, al-ʿarabīyah al-fuṣḥā) or Quranic Arabic is the standardized literary form of Arabic used from the 7th century and throughout the Middle Ages, most notably in Umayyad and Abbasid literary texts such as poetry, elevated prose and oratory, and is also the liturgical language of Islam. The first comprehensive description of ''Al-ʿArabiyyah'' "Arabic", Sibawayh's ''al''-''Kitāb'', was upon a corpus of poetic texts, in addition to the Qurʾān and Bedouin informants whom he considered to be reliable speakers of the ''ʿarabiyya''. Modern Standard Arabic is its direct descendant used today throughout the Arab world in writing and in formal speaking, for example prepared speeches, some radio and TV broadcasts and non-entertainment content. Whilst the lexis and stylistics of Modern Standard Arabic are different from Classical Arabic, the morphology and syntax have remained basically unchanged ...

Arabic (, ' ; , ' or ) is a Semitic languages, Semitic language spoken primarily across the Arab world.Semitic languages: an international handbook / edited by Stefan Weninger; in collaboration with Geoffrey Khan, Michael P. Streck, Janet C. E.Watson; Walter de Gruyter GmbH & Co. KG, Berlin/Boston, 2011. Having emerged in the 1st century, it is named after the Arabs, Arab people; the term "Arab" was initially used to describe those living in the Arabian Peninsula, as perceived by geographers from ancient Greece. Since the 7th century, Arabic has been characterized by diglossia, with an opposition between a standard Prestige (sociolinguistics), prestige language—i.e., Literary Arabic: Modern Standard Arabic (MSA) or Classical Arabic—and diverse vernacular varieties, which serve as First language, mother tongues. Colloquial dialects vary significantly from MSA, impeding mutual intelligibility. MSA is only acquired through formal education and is not spoken natively. It is ...

Gossypium Arboreum
''Gossypium arboreum'', commonly called tree cotton, is a species of cotton native to India, Pakistan and Bangladesh and other tropical and subtropical regions of the Old World. There is evidence of its cultivation as long ago as the Harappan civilization of the Indus Valley 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 attaining heights of one to two metres. Its branches are covered with pubescence and are purple in colour. 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 linear t ...

Central America
Central America ( es, América Central or ) is a subregion of the Americas. Its boundaries are defined as bordering the United States to the north, Colombia to the south, the Caribbean Sea to the east, and the Pacific Ocean to the west. Central America consists of eight countries: Belize, Costa Rica, El Salvador, Guatemala, Honduras, Mexico, Nicaragua, and Panama. Within Central America is the Mesoamerican biodiversity hotspot, which extends from northern Guatemala to central Panama. Due to the presence of several active geologic faults and the Central America Volcanic Arc, there is a high amount of seismic activity in the region, such as volcanic eruptions and earthquakes which has resulted in death, injury, and property damage. In the pre-Columbian era, Central America was inhabited by the indigenous peoples of Mesoamerica to the north and west and the Isthmo-Colombian peoples to the south and east. Following the Spanish expedition of Christopher Columbus' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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] |
