Stretch fabric is a type of textile that can expand and contract, allowing it to fit snugly around the body. This flexibility is achieved through the use of materials like spandex or lycra, which are often blended with other fibers such as cotton or polyester. Stretch fabrics are commonly used in clothing items like activewear, leggings, and swimwear, providing comfort and ease of movement. The unique properties of stretch fabric make it popular in various applications beyond clothing. It is also used in upholstery, medical garments, and even in some types of athletic gear. The ability to stretch and return to its original shape helps maintain the garment's fit and durability over time.
