What is Lycra? Composition and Properties of Lycra

Lycra®, also known as Spandex or Elastane, is a synthetic fiber made from a polyurethane-polyurea copolymer. Developed by DuPont in 1952, Lycra® has transformed the textile industry with its unique ability to stretch significantly and then return to its original shape. This remarkable elasticity is due to its chemical structure, which consists of long-chain synthetic polymers that provide both strength and flexibility.
