Polyurethane fiber is a synthetic textile material derived from polyurethane, a polymer known for its elasticity and durability. It is often blended with other natural or synthetic fibers like cotton, polyester, or nylon to enhance the properties of the resulting fabric. The key characteristic of polyurethane fiber is its stretch and recovery, meaning it can be stretched significantly and return to its original shape without permanent deformation. This elasticity makes it ideal for applications where movement and comfort are important.

The manufacturing process typically involves spinning polyurethane into fine filaments. These fibers can be produced in various forms, including staple fibers (short lengths) and continuous filaments (long, unbroken strands). The specific properties of the fiber can be adjusted during production, allowing for variations in stretch, strength, and texture.

Common uses for polyurethane fibers include activewear, hosiery, swimwear, and intimate apparel, where its stretch and shape retention are highly valued. It also finds application in medical textiles, such as compression garments, and in home furnishings like upholstery and carpets, contributing to their resilience and longevity. While offering significant advantages in terms of comfort and performance, polyurethane fibers may have limitations regarding heat resistance and susceptibility to certain chemicals.
