Spandex, also known as elastane (and branded as Lycra in some regions), is a synthetic fiber known for its exceptional elasticity and strength. Fabrics made with spandex or elastane are highly stretchable, offering up to five to eight times their original length without losing shape, making them ideal for applications requiring comfort, flexibility, and freedom of movement.
Typically blended with other fibers such as cotton, polyester, or nylon, spandex enhances the overall stretch, fit, and recovery of the fabric. It is lightweight, smooth, resistant to perspiration and body oils, and retains its form over time.
