Elastane, also known as Spandex or Lycra, is a synthetic fibre made primarily from polyurethane. It provides stretch and shape retention in garments like leggings, swimwear, socks, and jeans. However, its production involves toxic chemicals, including isocyanates, which pose risks to worker safety and the environment if not properly managed.
Elastane is almost always blended with other fibres, complicating recycling processes and reducing circularity. It is non-biodegradable, and even small proportions (typically 1–5%) can hinder the recyclability of finished products.
