What Is Spandex Fabric? Properties, Blends, and Uses

Spandex fabric is a textile containing spandex, a synthetic elastic fiber made primarily from segmented polyurethane. Also called elastane, spandex is blended with fibers such as cotton, polyester, or nylon to give clothing controlled stretch and recovery. It helps garments move with the body and return toward their original shape. Its actual comfort, breathability, and durability depend on the complete fabric construction, not spandex content alone.
