Spandex is a synthetic fiber known for its exceptional elasticity. It is often blended with other materials, such as cotton or polyester, to create stretchy fabrics used in various clothing items. Commonly found in activewear, swimwear, and undergarments, spandex allows for greater freedom of movement and comfort. Invented in the late 1950s by chemist Joseph Shivers, spandex is also known by the brand name Lycra. The fiber can stretch up to five times its original length and then return to its shape, making it ideal for form-fitting garments. Its durability and resistance to wear make it a popular choice in the fashion industry.
