Spandex, also known as elastane or Lycra, is a synthetic fiber renowned for its exceptional elasticity. It is produced through a complex chemical process involving the polymerization of a polyester-like substance with polyurethane.
Spandex is widely used in the textile industry, especially in clothing that requires stretchability, such as leggings and bras. The primary health concern with spandex is related to skin sensitivity or allergic reactions in rare cases; however, it is generally considered safe for most people. Due to its elasticity, it provides comfort and a snug fit in stretchable garments.
