A » Spandex, also known as elastane, is produced through the chemical synthesis of polyurethanes. This process involves creating a prepolymer by reacting a diisocyanate with a macroglycol. The resulting solution is then extruded through a spinneret to form fibers, which are subsequently heated to stabilize their elastic properties. This material is renowned for its exceptional elasticity and strength, making it ideal for use in sportswear, swimsuits, and other stretchable garments.
