What Is Spandex?

Spandex, also known as elastane, is a synthetic fibre made from polyurethane polymer. It is incredibly stretchy and elastic, making it a popular choice for a wide range of clothing items, particularly those that require flexibility and a snug fit.

The versatility of spandex can be attributed to its unique combination of properties, which include its excellent elasticity and resistance to degradation.

The primary characteristic of spandex is its exceptional ability to stretch and return to its original shape. This is due to the unique molecular structure of the polyurethane polymer, which contains both rigid and flexible segments.

When you stretch the fabric, the flexible segments straighten out, allowing for expansion. Once the tension is released, the segments return to their original position, making the fabric return to its initial state.

Spandex is often combined with other fibres to enhance the elasticity and fit of garments. Standard blends include natural fibres like cotton or wool and synthetic fibres like nylon or polyester. This versatility allows it to be used in various applications, such as:

  • Activewear and sportswear
  • Swimwear
  • Undergarments
  • Socks and hosiery
  • Compression garments
