Cotton is a soft, staple fiber Fiber, also spelled fibre, is a class of materials that are continuous filaments or are in discrete elongated pieces, similar to lengths of thread. They are very important in the biology of both plants and animals, for holding tissues together. Human uses for fibers are diverse. They can be spun into filaments, string or rope, used as a component that grows in a form known as a boll around the seeds A seed ( /ˈsiːd/ ), referred to as a kernel in some plants, is a small embryonic plant enclosed in a covering called the seed coat, usually with some stored food. It is the product of the ripened ovule of gymnosperm and angiosperm plants which occurs after fertilization and some growth within the mother plant. The formation of the seed completes of the cotton plant Gossypium is a genus of 39-40 species of shrubs in the mallow family, Malvaceae, native to the tropical and subtropical regions of both the Old World and the New World. The cotton plants, sources of commercial cotton fabric, are included in this genus, a shrub A shrub or bush is a horticultural rather than a strict botanical category of woody plant, distinguished from a tree by its multiple stems and lower height, usually less than 5–6 m tall. A large number of plants can be either shrubs or trees, depending on the growing conditions they experience. Small, low shrubs such as lavender, periwinkle and native to tropical and subtropical regions around the world, including the Americas The Americas, or America, are the lands of the Western hemisphere or New World, comprising the continents of North America and South America with their associated islands and regions. America may be ambiguous in English, as it is more commonly used to refer to the United States of America. The Americas cover 8.3% of the Earth's total surface area, India India, officially the Republic of India , is a country in South Asia. It is the seventh-largest country by geographical area, the second-most populous country, and the most populous democracy in the world. Bounded by the Indian Ocean on the south, the Arabian Sea on the west, and the Bay of Bengal on the east, India has a coastline of 7,517 and Africa Africa is the world's second-largest and second most-populous continent, after Asia. At about 30.2 million km² including adjacent islands, it covers 6% of the Earth's total surface area and 20.4% of the total land area. With a billion people (as of 2009, see table) in 61 territories, it accounts for about 14.8% of the World's human population. The fiber most often is spun into yarn Yarn is a long continuous length of interlocked fibers, suitable for use in the production of textiles, sewing, crocheting, knitting, weaving, embroidery and ropemaking. Thread is a type of yarn intended for sewing by hand or machine. Modern manufactured sewing threads may be finished with wax or other lubricants to withstand the stresses involved or thread and used to make a soft, breathable textile A textile is a flexible material consisting of a network of natural or artificial fibres often referred to as thread or yarn. Yarn is produced by spinning raw wool fibres, linen, cotton, or other material on a spinning wheel to produce long strands. Textiles are formed by weaving, knitting, crocheting, knotting, or pressing fibres together, which is the most widely used natural-fiber cloth in clothing The primary purpose of clothing is functional, as a protection from the elements. Clothes also enhance safety during hazardous activities such as hunting and cooking by providing a barrier between the skin and the environment. Clothes incidentally also provide a hygienic barrier, keeping toxins away from the body and limiting the transmission of today. The English name English is a West Germanic language that developed in England during the Anglo-Saxon era. As a result of the military, economic, scientific, political, and cultural influence of the British Empire during the 18th, 19th, and early 20th centuries, and of the United States since the mid 20th century, it has become the lingua franca in many parts of derives from the Arabic Arabic (العربية al-ʿarabīyah, ( Arabic pronunciation ) or عربي ʿarabi) is a Central Semitic language, thus related to and classified alongside other Semitic languages such as Hebrew and the Neo-Aramaic languages. In terms of speakers, Arabic is the largest member of the Semitic language family. It is spoken by more than 280 million (al) qutn قُطْن , which began to be used circa 1400.[1]
The chemical composition of cotton is as follows:
cellulose Cellulose is an organic compound with the formula n, a polysaccharide consisting of a linear chain of several hundred to over ten thousand β(1→4) linked D-glucose units 91.00% water Water is a ubiquitous chemical substance that is composed of hydrogen and oxygen and is essential for all known forms of life 7.85% protoplasm Protoplasm is the living contents of a cell that are surrounded by a plasma membrane. This term is not commonly used in modern cell biology. Protoplasm is composed of a mixture of small molecules such as ions, amino acids, monosaccharides and water, and macromolecules such as nucleic acids, proteins, lipids and polysaccharides. In eukaryotes the, pectins 0.55% waxes Wax refers to beeswax or another substance with similar properties. The traditional meaning, beeswax, refers to a substance secreted by bees and used by them in constructing their honeycombs. The term has come to refer more generally to a class of substances with properties similar to beeswax, enumerated below:, fatty substances 0.40% mineral salts In chemistry, salts are ionic compounds which can result from the neutralization reaction of acids and bases. Salts are ionic compounds composed of cations and anions (negative ions) so that the product is electrically neutral (without a net charge). These component ions can be inorganic such as chloride (Cl−), as well as organic such as acetate 0.20%
