CEY (Elastic Composite Yarn) is a novel type of elastic composite fiber created through a unique compounding process involving SSY/SPH materials. This advanced yarn maintains all the desired qualities of SSY elastic fibers such as resilience and a soft, dry feel. Moreover, it combines these features with enhanced fabric characteristics that include excellent elasticity and recovery, resistance to stains and sun damage, and superior moisture-wicking and quick-drying properties. The fabrics made from CEY are not only comfortable and durable but also feature a smooth appearance and moderate elasticity, which make them ideal for various clothing applications.
