Rug or Carpet Knot

(Glossary Term)

A segment of supplementary wrapping weft whose cut ends project above the surface of the carpet. Although called a “knot,” the yarn segments are not actually tied, but just wrapped around the warp yarns and are held in place by the ground weft yarns. Depending on the coarseness of the yarns and how closely they are set, the number of “knots” per square inch of a carpet can range from less than 50 to more than 1,000.
