what is elastane

Elastane, also known as spandex or Lycra, is a synthetic fiber renowned for its exceptional elasticity. It is a polyether-polyurea copolymer that was invented in 1958 by chemist Joseph Shivers at DuPont. Elastane is often used in combination with other fibers to create stretchy clothing and is used in a variety of garments, including athletic wear, swimwear, and denim. It is primarily known as Lycra in the UK, Ireland, Portugal, Spain, Latin America, Australia, and New Zealand, while in continental Europe, it is referred to by variants of elastane. Elastane is not biodegradable and its environmental impact is a growing concern in the fashion industry. It is composed of at least 85 percent polyurethane, a material derived from non-renewable raw materials such as crude oil and natural gas. Elastane is used in fabrics where stretch, flexibility, and comfort are important, and it is often blended with other fibers to create high-performance fabrics for use in sports and swimwear.
