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.
Claims22
A fabric consisting of a single layer of a non-woven substrate,
- wherein the non-woven substrate is treated with a finish comprising one or more flame retardant phosphorous compounds or nitrogen compounds,
- wherein the non-woven substrate is a non-woven fabric comprising cellulosic fibers and has a basis weight ranging from 3.0 to 8.0 ounces per square yard,
- wherein the finish is applied to the non-woven substrate in an amount ranging from 15 to 130 percent solids, based upon the weight of the non-woven substrate,
- wherein 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,
- wherein the non-woven substrate is a non-woven, stitchbonded fabric, and
- wherein the non-woven substrate comprises polyester fibers.
A fabric consisting of a single layer of a non-woven substrate,
- wherein the non-woven substrate is treated with a finish comprising an intumescent, flame retardant coating,
