Spandex: An Overview
Spandex, also known as elastane or Lycra, is a synthetic fiber known for its exceptional elasticity. It is a polyurethane-polyurea copolymer that was invented in 1958 by chemist Joseph Shivers at DuPont's Benger Laboratory in Waynesboro, Virginia. Spandex is often used in the production of a wide range of clothing including athletic wear, swimwear, and compression garments due to its stretchiness and ability to retain its shape.
Key Characteristics of Spandex
- Elasticity: Spandex is highly elastic, with the ability to stretch up to 5 times its original length and then return to its original shape.
- Durability: It is known for its durability and resistance to abrasion, making it suitable for activewear.
- Comfort: Spandex provides a comfortable and form-fitting feel, making it popular in clothing designed for physical activity.
- Moisture Management: Many spandex blends offer moisture-wicking properties, aiding in sweat evaporation during physical activities.
Applications of Spandex
Spandex is widely used in the production of:
- Activewear and sportswear
- Swimwear and wetsuits
- Compression garments and shapewear
- Undergarments
- Medical bandages
