How is lycra produced?

Answer 1

Lycra, also known as spandex or elastane, is produced through a process called polymerization, where a chemical reaction combines monomers to form long polymer chains. The primary monomer used is polyurethane, which is derived from petrochemicals. The resulting polymer is then spun into fibers, typically through a dry or wet spinning process, which involves dissolving the polymer in a solvent and extruding it through spinnerets. Once the fibers are formed, they are stretched and set to achieve their characteristic elasticity.
