COREVA™, the first biodegradable stretch denimCOREVA™ is an innovative technology developed and patented by Candiani Denim that uses a plant-based yarn obtained from natural rubber to replace synthetic, petrol-based yarns. Made from organic cotton wrapped around a natural rubber core, the result is a yarn that is completely plastic-free. By replacing conventional synthetic and petrol-based elastomers with a new, custom-engineered component, Candiani has created an innovative biodegradable stretch denim fabric – without compromising the elasticity, physical qualities, and durability of jeans.
