Spandex, also known as elastane is a commonly known synthetic fiber widely used in the clothing and medical industry due to its exceptional elastic properties. Spandex is a copolymer based on polyurea-polyurethane which was first manufactured by E. I. du Pont de Nemours and Company. The fibers of spandex are manufactured through various processes such as solution wet spinning, solution dry spinning, reaction spinning and melt extrusion. All the processes include the reaction with monomers to develop a prepolymer, after which it is reacted further through certain techniques to finally make the fibers. Among all the methods, dry spinning is the most preferred choice for manufacturing spandex fibers. Spandex fibers are significantly consumed in a wide range of textiles due to strength and strong elasticity as well its ability to return to its original shape after stretching as compared to ordinary fabrics. These fibers are especially incorporated in apparels such as skin tight garments, belts, competitive swimwear, cycling jerseys, leggings, gloves, activewear and athletic, aerobic and exercise garments. Spandex is generally mixed with synthetic and natural fiber such as polyester or cotton for clothing applications and contributes for a minimal percentage of the final fabric. In developed regions such as North America, spandex is mostly used in women clothing, and also accounts for a significant market share in clothing in economies such as the U.S.
