  • Method of making recyclable tufted carpets
    Patent number: 5630896
    Abstract: A recyclable thermoplastic tufted fabric made of a partially meltable primary backing and tufts tufted into the primary backing. The tufts are bonded to the backing by partially melting the backing to bond the tufts and applying a secondary backing. Such a carpet can be recycled through processes known to recycle polyester.
    Type: Grant

  • Texture carpets and rugs made from fiber blends
    Patent number: 5223317
    Abstract: A blend of low shrinkage polyester fibers and high shrinkage polyester fibers is described. In particular, the blend includes high shrinkage PET copolymers having boiling water shrinkages from 6 to 11 percent and low shrinkage PET copolymer fibers having a shrinkage of less than 3 percent. Textured carpets and rugs made from the blend consistently have better initial tuft end point definition and, in most cases, better bulk than corresponding polyester carpets made from conventional polyester fibers.
