Polyurethane fibers

As already mentioned, polyurethane fiber (Spandex or elastane) is a synthetic fiber known for its exceptional elasticity (or stretchability). Spandex is stronger, lighter, and more versatile and durable than rubber.

In fact, Spandex fibers can be stretched to almost 500% of their length. The Spandex fiber technology was invented in 1959, and when first introduced it revolutionized many areas of the clothing industry and found a number of important replacement applications for rubbers previously used in many applications.

Spandex fiber is round in cross-section, thus offering extra elasticity and good elongation. The material has superior resistance to degradation caused by sunlight, perspiration and chlorine, making it ideal for various kinds of active wear and swimwear.
