Elastane is a synthetic fiber known for its exceptional elasticity. Often blended with other materials like cotton or polyester, it allows fabrics to stretch and return to their original shape. This property makes elastane popular in clothing items that require flexibility, such as activewear, swimwear, and undergarments. Developed in the late 1950s, elastane is commonly referred to by brand names like Lycra or Spandex. Its lightweight and durable nature contributes to the comfort and fit of garments, making it a staple in the fashion industry. Elastane's ability to enhance the wearability of fabrics has revolutionized modern clothing design.
