what is lycra fabric

Lycra fabric, also known as spandex or elastane, is a highly elastic synthetic fabric that can stretch to 5-8 times its usual size. Lycra is a brand name for elastane, and these terms are often used interchangeably. It is a polymer composed of long chains of monomers connected with a special type of acid, and it is highly resistant to heat. Lycra is used in a wide variety of consumer textiles, especially in form-fitting garments such as underwear for men and women. The fabric is known for its exceptional elasticity, lasting shape, and comfortable fit, making it a popular choice for activewear and other types of apparel. When shopping for garments made with Lycra, it is important to look for the LYCRA® brand name on the label or hang tag to ensure the authenticity of the fiber.
