Abstract

A method for increasing heat dissipation from the smolder or open flame site of an upholstered article by interposing a fire barrier material between the outer upholstery fabric and the filler or padding materials. The fire barrier material is formed by coating a fibrous substance, such as glass fibers, carbon fibers, and the like with a latex containing a finely divided heat conductive metal.

Claims

1. A fire resistant upholstered article comprising an outer upholstery fabric that houses and contains filler materials, and a fire barrier material interposed between the outer upholstery fabric and the filler materials, comprising a fibrous substance selected from the group consisting of glass, carbon, polyaramid, polybenzimidazole, polymeta-phenylene diamine isophthalate, and combinations thereof, coated with a latex of enhanced thermal conductivity containing a finely divided heat conductive metal selected from the group consisting of aluminum, copper, nickel, and mixtures thereof, and wherein said interposed fire barrier-upholstered fabric has a porosity rating of less than 10 cubic feet of air per minute per square foot measured at a pressure of 1/2 inch of water.

2. The fire resistant upholstered article of claim 1, wherein the fibrous substance is glass.

3. The fire resistant upholstered article of claim 1, wherein the fibrous substance is carbon.

4. The fire resistant upholstered article of claim 1, wherein the fibrous substance is polyaramid.

5. The fire resistant upholstered article of claim 1, wherein the fibrous substance is polybenzimidazole.

6. The fire resistant upholstered article of claim 1, wherein the fibrous substance is polymetaphenylene diamine isophthalate.

7. The fire resistant upholstered article of claim 1, wherein the heat conductive metal is aluminum.

8. The fire resistant upholstered article of claim 1, wherein the heat conductive metal is copper.

9. The fire resistant upholstered article of claim 1, wherein the heat conductive metal is nickel.
