  • Patent number: 5845476
    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.

  • Patent number: 5655358
    Abstract: A cut resistant support yarn suitable for wrapping with an additional yarn covering. The cut resistant support yarn includes a core including only a first cut resistant strand, a second cut resistant strand wrapped in a clockwise direction around the core, and a third cut resistant strand wrapped in a counter clockwise direction around the core. One of the second and third cut resistant strands forms an inner covering surrounding the core, and the other of the second and third cut resistant strands forms an outer covering surrounding the core and the inner covering.
