  • Helically wrapped yarn
    Patent number: 4346553
    Abstract: A core yarn has a plurality of wrapper yarns wrapped under tension in both the clockwise and counterclockwise directions. The core is composed of staple fibers having substantially no twist so that the core has substantially zero tensile strength. The tensions on the wrapper yarns are balanced by each other and are so high as to compress the core and impart to the core a sinuous configuration along its length.
