Spandex , Lycra or elastane is a synthetic fiber known for its exceptional elasticity. The name "spandex" is an anagram of the word "expands". Dupont textiles scientist Joseph C. Shivers was determined to find a fiber to replace rubber in garments. He made a breakthrough in the early s when he used an intermediate substance to modify Dacron polyester.
After nearly a decade of research the fiber was perfected in Originally called Fiber K, DuPont chose the more rich trade name Lycra to distinguish its brand of spandex fiber. Spandex fibers are produced in four ways: All of these methods include the initial step of reacting monomers to produce a prepolymer.
Once the prepolymer is formed, it is reacted further in various ways and drawn out to make the fibers. The solution dry spinning method is used to produce over In the post World War II era, DuPont Textiles Fibers Department, which was formed in , became its most popular division, dominating the synthetic fiber market worldwide. The "need" was a better fiber solution for women's girdles , which were commonly made of rubber at the time. DuPont became interested in developing a synthetic elastic fiber in the s, which was perfected by chemist Joseph Shivers in Spandex's transformative nature allowed it to be incorporated into other garments besides girdles and undergarments.
By the mids, girdle sales began to drop with the emergence of the Women's Liberation Movement. Girdles came to be associated with anti-independence and emblematic of an era that was quickly passing away.
In response, DuPont reimagined Lycra as the aerobic fitness movement emerged in the s. The fiber proved to be especially popular in mid-thigh-length shorts worn by cyclists. In the s a variety of other items made with Spandex proved popular, including a successful line of body-shaping foundation garments sold under the trade name Bodyslimmers. As the decade progressed, shirts, pants, dresses, and even shoes were being made with spandex blends, and mass-market retailers like Banana Republic were using it for menswear.
The elasticity and strength stretching up to five times its length , of spandex has been incorporated into a wide range of garments, especially in skin-tight garments. A benefit of spandex is its significant strength and elasticity and its ability to return to the original shape after stretching and faster drying than ordinary fabrics. For clothing, spandex is usually mixed with cotton or polyester , and accounts for a small percentage of the final fabric, which therefore retains most of the look and feel of the other fibers.
In North America it is rare in men's clothing, but prevalent in women's. From Wikipedia, the free encyclopedia. Not to be confused with Spanx.
