DESCRIPTION
Core spun yarn is made by spinning staple fibers around the core yarn. For extra strength and conductivity, the core yarn can either be a high-tenacity filament made of polyester or metal. Elastic fibers such as spandex and PTT can be used, including PBT, PBT, PBT, and others. The yarn is made stretchier by using the core. Spandex cotton core spun yarn can be used widely.
