Spandex, or elastane, is a synthetic fiber Synthetic fibers are the result of extensive research by scientists to improve upon naturally occurring animal and plant fibers. In general, synthetic fibers are created by forcing, usually through extrusion, fiber forming materials through holes into the air, forming a thread. Before synthetic fibers were developed, artificially manufactured known for its exceptional elasticity In physics, elasticity is the physical property of a material when it returns to its original shape after the stress under which it deforms is removed. The relative amount of deformation is called the strain. It is stronger and more durable than rubber Natural rubber is an elastomer that was originally derived from a milky colloidal suspension, or latex, found in the sap of some plants. The purified form of natural rubber is the chemical polyisoprene, which can also be produced synthetically. Natural rubber is used extensively in many applications and products, as is synthetic rubber, its major non-synthetic competitor.[citation needed] It is a polyurethane A polyurethane, IUPAC abbreviation PUR, but commonly abbreviated PU, is any polymer consisting of a chain of organic units joined by urethane links. Polyurethane polymers are formed through step-growth polymerization by reacting a monomer containing at least two isocyanate functional groups with another monomer containing at least two hydroxyl (-polyurea Polyurea is a type of elastomer that is derived from the reaction product of an isocyanate component and a synthetic resin blend component through step-growth polymerization. The isocyanate can be aromatic or aliphatic in nature. It can be monomer, polymer, or any variant reaction of isocyanates, quasi-prepolymer or a prepolymer. The prepolymer, copolymer A heteropolymer or copolymer is a polymer derived from two monomeric species, as opposed to a homopolymer where only one monomer is used. Copolymerization refers to methods used to chemically synthesize a copolymer that was invented An invention is a new configuration, device, or process. Some inventions are based on pre-existing models or ideas and others are radical breakthroughs. Inventions can extend the boundaries of human knowledge or experience in 1959 by chemist Joseph Shivers Joseph Clois Shivers, Jr. was an American chemist who lived in West Chester, Pennsylvania. Shivers spent much of the 1950s developing Spandex while working for DuPont. He was awarded the prestigious Olney Medal for Achievement in Textile Chemistry for his work at DuPont E. I. du Pont de Nemours and Company , commonly referred to as DuPont or Du Pont, is an American chemical company that was founded in July 1802 as a gunpowder mill by Eleuthère Irénée du Pont. DuPont is currently the world's second largest chemical company (behind BASF) in terms of market capitalization and fourth (behind BASF, Dow Chemical and's Benger Laboratory in Waynesboro, Virginia Waynesboro, deriving its name from General Anthony Wayne, is an independent city located within the confines of Augusta County in the U.S. state of Virginia. The population was 19,520 at the 2000 census, and estimated at 21,454 for 2006. It is located in the Shenandoah Valley, near many important historical markers of the Civil War and Shenandoah. When first introduced, it revolutionized many areas of the 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 industry An industry is the manufacturing of a good or service within a category. Although industry is a broad term for any kind of economic production, in economics and urban planning industry is a synonym for the secondary sector, which is a type of economic activity involved in the manufacturing of raw materials into goods and products.
"Spandex" is a generic name and not derived from the chemical name of the fiber, as are most manufactured fibers, but an anagram of the word expands.[1] "Spandex" is the preferred name in North America North America is the northern continent of the Americas, situated in the Earth's northern hemisphere and in the western hemisphere. It is bordered on the north by the Arctic Ocean, on the east by the North Atlantic Ocean, on the southeast by the Caribbean Sea, and on the west by the North Pacific Ocean; South America lies to the southeast. North; in many European countries it is referred to as "elastane".
A brand name associated with spandex is Lycra.
