Abstract
The present invention relates to a yarn core construction suitable for forming a flexible composite yarn having a fiberglass component. The resulting yarn has good cut and abrasion resistance qualities without sacrificing knittability, flexibility and suppleness. A normally hard to knit fiberglass strand is wrapped with a sheath strand at a rate of at least 8 turns per inch. The core thus formed provides all of the benefits of a fiberglass supported yarn without experiencing any of the manufacturing difficulties normally associated with fiberglass yarns. The core may also be provided with a multi-layer covering to balance the yarn and to further improve knittability.
