The invention relates to a process for producing particle/polymer composites using a substrate S comprising shredded textile fabric products and a polymeric binder P, therewith providing a new method of recycling/upcycling textile waste. Furthermore, a process for the manufacturing of a molded article obtained from the textile-based particle/polymer composite and the use thereof are disclosed.

A pipe liner comprising a nonwoven felt, and process for making said nonwoven felt, the nonwoven felt consisting essentially of 0 to 85 weight percent polyester staple fibers and 15 to 100 weight percent para-aramid staple fibers, the nonwoven felt having a basis weight of 250 to 600 grams per square meter and a thickness of 2.0 to 5.0 mm; wherein: 20 to 100 weight percent of the total amount of para-aramid staple fibers are re-purposed para-aramid staple fibers, 0 to 80 weight percent of the total amount of para-aramid staple fibers are crimped virgin para-aramid staple fibers having a uniform cut length, and at least 50 weight percent of the total amount of the combined polyester and para-aramid staple fibers are crimped staple fibers.

There is provided a fiber molded body for sound absorbing/sound insulation materials, which is lightweight and has excellent sound absorption performance. The fiber molded body for sound absorbing/sound insulation materials of the present invention is a fiber molded body for sound absorbing/sound insulation materials comprising uncolored ultrafine chemical fibers and colored fibers or reclaimed fibers, wherein the single fiber fineness of the ultrafine chemical fibers is 0.01 to 0.5 dtex, the content of the ultrafine chemical fibers is 5 to 70 mass % and the content of the colored fibers or the reclaimed fibers is 20 to 60 mass %, in the fiber molded body for sound absorbing/sound insulation materials.

A leather substrate formed from waste leather and its method of production, particularly a leather substrate made up substantially of a collagen fibril matrix.

A fiber processing device includes a drum having a plurality of openings on an outer peripheral surface, sieving a raw material containing fibers, and configured to rotate about a rotation axis, a housing that supports the drum, a guide portion (convex portion) provided on an outer peripheral surface of the drum; and a restriction portion (bearing) that restricts movement of the drum in a direction of the rotation axis by contacting the convex portion. At least one of the restriction portion and the guide portion is configured to rotate about an axis (rotation axis) orthogonal to the rotation axis.

The invention relates to a process for producing non-woven fabric-like composite materials, novel non-woven fabric-like composite materials, articles made therefrom and their use. In particular the fabric-like composite materials are derived from shredded polymer-glued or polymer-coated paper products and coffee grounds as raw material.

Covers comprising a nonwoven fabric including a plurality of recycled polyester fibers, such as a plurality of staple fibers, is provided. The plurality of recycled polyester fibers may be formed from a post-consumer polyester, a post-industrial waste polyester, or a combination thereof. The covers provide desirable vapor transmission while also providing an improved hydrostatic head. The covers may be provided in a variety of configurations. Methods of forming such covers are also provided.

Provided herein is a method for aligning discontinuous fibres comprising: providing a stream of discontinuous fibres in a dispersion medium; applying a shear stress to the dispersion medium to align at least a portion of the discontinuous fibres; and disposing the at least a portion of the aligned discontinuous fibres on a substrate thereby providing a layer of substantially aligned discontinuous fibres. Also provided are discontinuous fibres aligned by such method and a composite material formed from the aligned discontinuous fibres.

A fibrous nonwoven structure formed of a blend of cellulose pulp fibers and melt spun polymer filaments is disclosed. The structure may include a distribution of a plurality of macroscopically visible shaped particles of substantially similar size and shape, included in the blend. The structure may also include outer scrim layers formed of melt spun polymer filaments. A method of manufacturing the fibrous nonwoven structure is also disclosed.

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.
