    摘要: Tufted carpets bonded with thermoplastic binders and having improved resistance to fuzz formation due to removal of pile yarn filaments from tuft bundles comprise one or more backings, face yarn that forms a pile on one side and stitches on an opposite side, a thermoplastic binder that binds stitches and the backing or backings, and an organic polymer that bonds filaments of the stitches. Processes for making carpets comprise applying to a stitched side of a tufted backing a liquid stitch bind composition comprising an organic polymer component, removing a liquid component of the composition to bond filaments of the stitches and bonding stitches and one or more backings with a thermoplastic binder that is melted or applied as a melt in contact with the stitched side and the backing or backings and solidified.

    摘要: An improved stabilizing tool includes a body with a pocket, and a roller rotatably disposed in the pocket. The body includes a fluid passageway formed axially therethrough. The passageway has a first zone wherein the pressure of the fluid is relatively high and a second zone wherein the pressure is relatively low. A first conduit provides fluid communication between the first zone and an interior of the roller for the ingress of fluid to the interior, and a second conduit provides fluid communication between the interior of the roller and the second zone for the egress of the fluid back to the fluid passageway.
