  • Tufted pile structure having binder concentrated beneath the backstitches
    Patent number: 6726976
    Abstract: A concentrate of binder at the tufts produces a lighter and more flexible carpet, which allows for direct attachment of hook-and-loop means on the carpet backing. Thermoplastic binder yarns are pinned by the pile yarns against the primary backing. Subsequent application of heat melts the binder yarns and fuses the tufts and primary backing together. An alternate embodiment uses highly shrinkable binder sheet placed over the backing before tufting, instead of the binder yarns.
