Abstract
Official abstract text for this publication.
Disclosed are rebond polyurethane foams comprised of a plurality of polyurethane foam particles bound together to form a matrix. Reclaimed carpet material is distributed within the matrix of foam particles as a filler material. Also disclosed are methods for the manufacture of the rebond polyurethane foams disclosed herein.
First claim
Opening claim text (preview).
What is claimed is: 1. A rebond polyurethane foam, comprising: a plurality of preformed polyurethane foam particles bonded to one another to form a matrix; and reclaimed carpet material distributed within the matrix of polyurethane foam particles, wherein the reclaimed carpet material comprises a population of thermoplastic fibers having non-uniform linear fiber densities; and wherein the reclaimed carpet material is present in an amount of at least 35 parts by weight relative to the total amount of preformed polyurethane foam particles and reclaimed carpet material present in the rebond polyurethane foam. 2. The rebond polyurethane foam of claim 1 , wherein the reclaimed carpet material is present in an amount of from 35 to 50 weight percent of the total weight of the rebond polyurethane foam. 3. The rebond polyurethane foam of claim 1 , wherein the reclaimed carpet material comprises fibers of nylon 6, nylon 6,6, polyethylene, polypropylene, polyester, or any combination thereof. 4. The rebond polyurethane foam of claim 1 , wherein the reclaimed carpet material comprises natural fibers. 5. The rebond polyurethane foam of claim 1 , wherein the reclaimed carpet material comprises post consumer carpet material. 6. The rebond polyurethane foam of claim 1 , having a volumetric density in the range of from 1 to 50 pounds per cubic foot. 7. The rebond polyurethane foam of claim 6 , having a volumetric density in the range of from 1 to 25 pounds per cubic foot. 8. The rebond polyurethane foam of claim 1 , having a volumetric density greater than 8 pounds per cubic foot. 9. The rebond polyurethane foam of claim 1 , wherein the reclaimed carpet material is present in an amount of at least 50 parts by weight relative to the total amount of preformed polyurethane foam particles and reclaimed carpet material present in the rebond polyurethane foam.
