description Spandex (Elastane) Overview
Spandex, commonly called elastane outside North America, is a synthetic fiber composed primarily of segmented polyurethane. Developed for commercial use by DuPont chemist Joseph Shivers in the late 1950s, it can stretch several times beyond its original length and recover much of its shape. Because it is usually blended with fibers such as cotton, polyester, or nylon, it is widely used in activewear, swimwear, underwear, hosiery, fitted garments, and other textiles that require elasticity and close body movement.

help Spandex (Elastane) FAQ
Are spandex and elastane the same fiber?
Yes. Spandex is the name commonly used in North America, while elastane is more common in Europe, and both describe a synthetic fiber made primarily from segmented polyurethane.
Who invented spandex, and was Lycra the original name?
DuPont chemist Joseph Shivers developed the commercial fiber in the late 1950s as a replacement for rubber in garments. Lycra is a trademarked brand of elastane, not the generic name of the material.
Why is spandex blended with cotton or polyester instead of used alone?
A small elastane content can give cotton jeans, polyester sportswear, or nylon swimwear stretch and shape recovery without dominating the fabric. Everyday stretch clothing often contains only a modest percentage because pure elastane would lack the desired feel, durability, and structure.
Does heat damage elastane clothing?
Yes, repeated high heat can weaken elastane and reduce its ability to recover after stretching. Cool washing and low-temperature drying are therefore safer for leggings, swimwear, and other garments containing spandex.
