A fibrous structure having one or more vertically lapped layers having a first surface and a second surface and a facing layer secured to the first surface of the vertically lapped layer. The fibrous structure is adapted to be used in a flooring assembly. The fibrous structure may include a mesh and/or a backing layer on the second surface of a vertically lapped layer. The fibrous structure exhibits improved performance in below room testing and/or in-room testing as compared with traditional materials of the same thickness.

Architectural flooring underlayment

A fibrous structure including one or more nonwoven material layers comprising a fiber matrix, where the fiber matrix comprises polymeric binder fibers having a softening and/or melting temperature of about 190° C. or greater, where the article is adapted to withstand temperatures of about 190° C. or greater while in use; and where the article is a thermoacoustic insulation material.

Polymeric nonwoven structure for use in high temperature applications

A nonwoven composite for high temperature applications requiring Sow flammability, smoke, and/or toxicity, including a fibrous structure having one or more nonwoven material layers including a scrim layer. The scrim is formed from inorganic fibers, at least some of which are adapted to withstand temperatures of up to about 1150° C. The scrim is formed from a wet-laying process. The composite further comprises one or more fiber matrix layers.

Functional nonwoven scrim for high temperature applications requiring low flammability, smoke, and toxicity

An acoustic composite comprising a plurality of discrete air flow resistive layers layered on top of each other including a top layer and one or more lofted fibrous layers produced by a lapping process, the top layer having a specific air flow resistance that is greater than a specific air flow resistance of the one or more lofted fibrous layer.

Multi-impedance composite

A fibrous structure including one or more nonwoven material layers comprising a fiber matrix, where the fiber matrix comprises polymeric binder fibers having a softening and/or melting temperature of about 190&#xb0; C. or greater, where the article is adapted to withstand temperatures of about 190&#xb0; C. or greater while in use; and where the article is a thermoacoustic insulation material.

An acoustic material comprising one or more acoustic composite layers; and a facing layer, wherein the one or more acoustic composite layers are formed of a nonwoven sound absorption material; wherein the facing layer is permeable; and wherein the facing layer is attached to a top surface of the one or more acoustic composite layers. The facing layer may optionally include metallic components or a metallized outer surface. The acoustic material may optionally include a pressure sensitive adhesive material on an opposing side of the one or more acoustic composite Sayers to enable installation of the acoustic material. The facing layer may include a permeable scrim, a perforated film, or a perforated foil. The facing layer may be metalized on its top exposed surface to provide infrared heat reflection, and a corrosion resistant coating may be applied on top of the metalized layer if required to stabilize the metal coating.

Aluminized faced nonwoven materials

A flooring assembly comprising at least one first lofted lapped or airlaid bulk absorber layerfor acoustic absorption and compression resistance; at least one impedance layerfor one or more of acoustic impedance, compression resistance, and stiffness; at least one second lofted lapped airlaid bulk absorber layerfor acoustic absorption and compression resistance; and one or more optional densified fibrous air-flow resistive layers
