Thermally Protective Flame Retardant Fabric
First Claim
1. A fabric consisting of a single layer of a non-woven substrate treated with a finish consisting essentially of an intumescent, flame retardant coating,wherein the non-woven substrate is chosen from needlepunched, spunbonded, thermalbonded, spunlaced, resin bonded, and stitch bonded fabrics comprising cellulosic fibers, said non-woven substrate having a basis weight ranging from 3.0 to 8.0 ounces per square yard, andwherein the single-layer, finished fabric has a thickness ranging from 0.01 to 0.15 inches and a contact thermal protective performance value of at least 4.5.

Abstract
A thermally protective, flame retardant fabric includes a substrate treated with a combination of a flame retardant agent and an intumescent agent. The substrate includes non-thermoplastic fibers or a blend of non-thermoplastic fibers and thermoplastic fibers having a basis weight ranging from 2.0 to 15.0 ounces per square yard. The fabric has a contact thermal protective performance value of at least 4.5 and a contact thermal protective performance efficiency greater than 1.1. Applications of the fabric include protective garments, articles of furniture, vehicle components, building components, electrical components, decorative components, appliances, and containers.
