Disclosed is shock absorbing pad having a composite nonwoven pad having a nonwoven construction, wherein the composite nonwoven pad has a face surface and an opposed back surface and comprising a nonwoven blend of fibers and a heat set binder material. The nonwoven construction of the composite nonwoven pad provides for a vertical water drainage capability of the composite nonwoven pad, and wherein the vertical water drainage capability is from 10 inches per hour to 500 inches per hour as determined by ASTM D3385.

The present invention relates to a method for producing a recycled insulating material from insulating wool, said method comprising the steps of: comminuting insulating wool to give a first intermediate comprising fibre balls; adding binder to the first intermediate to give a second intermediate; hot-pressing the second intermediate into the desired shape, to give a third intermediate; and curing the third intermediate to give the recycled insulating material. The present invention further relates to a method for recycling insulating wool, an apparatus for processing insulating wool, and a fibre-reinforced foam. The invention additionally embraces a fire-resistant wood-based material and a method for producing it.

Filter media comprising a filtration layer comprising synthetic fibers (e.g., pleatable backer layer) and related components, systems, and methods associated herewith are provided. In some embodiments, the filtration layer comprising synthetic fibers may be a non-woven web comprising a blend of coarse and fine diameter fibers. The filtration layer comprising synthetic fibers may be designed to have desirable performance properties without compromising certain mechanical properties, such as the pleatability of the media. In some embodiments, a filter media, described herein, may comprise the filtration layer comprising synthetic fibers and an efficiency layer. Filter media, as described herein, may be particularly well-suited for applications that involve filtering air, though the media may also be used in other applications.

A method of producing a sandwich panel core of mineral wool fibres from a cured mineral fibre product includes the steps of providing a cured mineral fibre product with a dual density having a top layer with mineral fibres with a first density and a base layer having mineral fibres with a second density, the second density is at least two times lower than said first density. The top layer and the base layer have different fibre orientations. Further steps including cutting the mineral fibre product into a plurality of lamellae, rotating the lamellae 90 degrees, and re-joining the lamellae so that the top layers with the first density are vertically oriented.

The present disclosure features a composite fabric, including a nonwoven layer including polymeric fibers and/or filaments; a crosslinked cellulose layer including crosslinked cellulose fibers; wherein the crosslinked cellulose layer is positioned opposed to the nonwoven layer (e.g., without an intervening layer different from the crosslinked cellulose layer and the nonwoven layer; in some embodiments, the crosslinked cellulose layer is immediately adjacent to the nonwoven layer); and an interfacial region between the nonwoven layer and the crosslinked cellulose layer, the interfacial region including physically entangled polymeric fibers and/or filaments from the nonwoven layer and crosslinked cellulose fibers from the crosslinked cellulose layer. The nonwoven layer and the crosslinked cellulose layer of the composite fabric are mechanically inseparable in a dry state.

A thermal runaway barrier for at least significantly slowing down a thermal runaway event within a battery assembly. The thermal runaway barrier includes a layer of a nonwoven fibrous thermal insulation comprising a fiber matrix of inorganic fibers, thermally insulative inorganic particles of irreversibly or permanently expanded expandable inorganic material dispersed within the fiber matrix, and a binder dispersed within the fiber matrix so as to hold together the fiber matrix. An optional organic encapsulation layer may also be used to encapsulate the nonwoven fibrous thermal insulation.
