Spandex

Spandex or elastane is a synthetic fiber known for its exceptional stretchability. It is stronger and more durable than rubber, its major plant competitor. It was invented in 1959, and when first introduced it revolutionized many areas of the clothing industry.

Spandex is the preferred name in North America, while elastane is most often used elsewhere. A well-known trademark for spandex or elastane is DuPont's brand name Lycra, another trademark (also DuPont's) is Elaspan.
