Methods of making an artificial leather substrate from leather waste (e.g., shavings, such as wet blue, and/or pulverized trim scrap) and products formed using the artificial leather substrate are disclosed. In one example, the artificial leather substrate comprises a composite web comprising leather waste mixed with a lightweight web, a lightweight web atop the composite web, and another lightweight web atop the first lightweight web. A method of making the artificial leather substrate includes the steps of mixing one or more fiber components, leather shavings, and/or pulverized leather trim scrap to form the composite web; needle punching the composite web; and bonding the composite web.

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 disclosed acoustic insulator mat includes a first absorber layer made of a non-woven fibrous material. The non-woven fibrous material comprises a mesh of intertwined fibers that defines a plurality of cavities. The first absorber layer has a first side and a second side. Peripheral cavities are arranged along the second side of the first absorber layer between peripheral fibers. A coating is disposed on the second side of the first absorber layer. The coating is adhered to the peripheral fibers and thus includes a plurality of discontinuities at the peripheral cavities such that the coating provides a partial barrier to noise at the second side of the first absorber layer. The acoustic insulator mat may optionally include a second absorber layer that is retained on the first absorber layer by the coating. A method of manufacturing the acoustic insulator mat is also disclosed.

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.

A preparation process of spunlace intertwining type recycled cow leather comprises a material preparation process, a cow leather fiber web forming process, as well as a mixed fiber web forming process, an overlapped web forming process, a base fabric manufacturing process and a cow leather finished product manufacturing process which are sequentially arranged according to a preparation process flow; the base fabric manufacturing process comprises a buffing process, a single-side immersion treatment process and an ironing process which are sequentially arranged for manufacturing the overlapped web into the base fabric; and the single-side immersion treatment process comprises the steps of subjecting a single side of the base fabric to single-side coating treatment of the water-based PU material or the oil-based PU material by adopting an inverted feeding device and using a water-based PU material or an oil-based PU material as a coating so as to form a single-side permeable immersion layer of the base fabric.

A fiber structure manufacturing apparatus includes: a defibration unit that pulverizes and defibrates a fiber raw material that contains fibers; a transportation unit that transports a defibrated material after defibration by the defibration unit; a melting-material mixing unit that mixes a melting material into the defibrated material transported by the transportation unit; a fibrous web forming unit that forms a fibrous web by causing a mixture of the defibrated material and the melting material to accumulate; a sheet supplying unit that supplies a shape retainer sheet to the fibrous web; and a heating-and-pressing mechanism that forms a fiber structure by heating and pressing the fibrous web after the shape retainer sheet is supplied; wherein the sheet supplying unit supplies the shape retainer sheet in such a state that nap is raised on a surface, of the shape retainer sheet, that is to be in contact with the fibrous web.

In accordance with one embodiment of the present disclosure, a nonwoven web may be manufactured by a process that includes forming a bicomponent fiber and forming the bicomponent fiber into the nonwoven web. The bicomponent fiber may comprise one or more primary polymer regions and two or more secondary polymer regions. The primary polymer regions may comprise polyethylene. The secondary polymer regions may comprise polypropylene, polyester, or polyamide. The primary polymer regions may comprise at least 2.5 wt. % of polypropylene, polyester, or polyamide, or the secondary polymer regions may comprise at least 2.5 wt. % of polyethylene, or both.
