SYNCORE - COTTON WRAPPED POLY CORE

Core Threads - are made by spinning a staple wrapper of cotton around a continuous filament of polyester fibers. Afterwards, two or more of these single yarns are twisted together to form the thread. Core threads have a fibrous surface giving them good lubricity characteristics and also a continuous filament core that contributes to high strength and durability. When wrapped with a cotton wrap, core threads have very good needle hear resistance. Core threads are used in everything from fine blouses to heavy coveralls and overalls.
