Lycra is a synthetic fiber made from polyurethane and was first produced by DuPont in 1959. It is lightweight, stretchable, and form-fitting with greater durability than other similar fibers. Spandex is a synthetic fiber made from polymer and was first produced by DuPont in 1962. It is known for its elasticity, low moisture absorbency, and high tensile strength. Lycra fabric is typically used in sportswear such as swimsuits, yoga wear, and leggings, while spandex fabric is typically used in items like girdles and underwear due to its increased elasticity.
