Core-spun yarns
Consist of a filament base yarn, with a loose fiber exterior wrapping which has not zet been twisted into a yarn. The polyester filament is often wrapped with a cotton outer layer in order to provide strength and resilience that is associated with polyester, along with the moisture-absorbent aesthetics and dye affinity of cotton. Sewing thread as well as household and apparel fabrics are made from these yarns.
