Abstract: A textile barrier for containment of liquid hydrocarbons comprises a layer of viscosity modifier, wherein the viscosity modifier disperses into and raises the viscosity of the liquid hydrocarbon. A layer of absorbent may be positioned to contact the liquid hydrocarbon before the viscosity layer. The textile barrier does not significantly obstruct flow of water.

Abstract: A composite flame barrier includes at least two layers of nonwoven flame resistant fibers, and at least one active chemical layer including a heat absorbing intumescent or endothermic compound, the active chemical layer being mechanically bound to and at least partially embedded within the nonwoven fiber layers. The composite flame barrier is particularly useful in applications that require a flexible, extended time fire barrier. Such applications include, for example, fuel line, process pipeline and valve protection when transporting combustible liquids; structural steel fireproofing, electrical cable wrap and fire-rated wall assemblies, especially those requiring two, three and four hour fire-ratings, when tested according to ASTM E-119 or similar testing methods and standards.

Abstract: A water permeable and liquid hydrocarbon-impermeable textile barrier is provided. The textile barrier consists of a textile material as a substrate layer, a layer of a hydrophobic organic chemical swellable in liquid hydrocarbons and a cover layer consisting of a textile material. All three layers are combined together by the needlepunching process in a needle loom. The textile barrier does not significantly obstruct flow of water. The textile barrier allows water to freely drain through.
