MIT engineers develop recyclable elastic yarn

A new recyclable yarn that can be melted, re‑spun and used again has entered the textile market, offering performance comparable to conventional spandex‑based fibers. Developed by a consortium of material scientists and manufacturers, the yarn combines high tensile strength with exceptional elasticity, matching the stretch and recovery characteristics that designers and athletes typically rely on from synthetic elastane blends.

Industry analysts say the yarn’s closed‑loop recyclability could reduce textile waste and lower the carbon footprint of stretch‑focused apparel, activewear, and technical fabrics. By allowing garments to be reclaimed and regenerated without loss of functional properties, the material promises a more sustainable supply chain while maintaining the durability and comfort standards expected by consumers.
