A process (1, 101, 201) for separating a fibrous target component (21) from textile waste (2, 5) is shown, said textile waste (2, 5) containing the target component (21) and at least one ancillary component (22), whereby the target component (21) consists of water-swellable textile fibers (51) with a density higher than the density of water, the process (1, 101, 201) comprising the steps: a) dispersing the comminuted textile waste (5) in an aqueous solution (7) to obtain a suspension (8) containing the textile waste (5), and b) separating the dispersed textile waste (5) into a high-density target fraction (81) comprising the target component (21), and a low-density residual fraction (82) comprising the at least one ancillary component (22), according to the respective density of said components (21, 22). In order to provide a reliable, fast process for the separation of water-swellable fibers from other textile fibers which are similar in density, it is proposed, that the aqueous solution (7) is an alkaline aqueous solution (7) and the target component fibers (51) are swelled in the alkaline aqueous solution (7) prior to step b), thereby increasing the density and weight of said target component (21) relative to the density and weight of the ancillary component (22).

A method for preparing a composite material that includes the steps of: (i) heat treating natural lignocellulosic fibers at a temperature of 130 to 320 C. for 2 minutes to 24 hours in an atmosphere oxygen-deficient in and in the presence of water vapor, and (ii) mixing the heat treated natural lignocellulosic fibers with at least one thermoplastic polymer in the molten state and whose melting point is less than or equal to 230 C. The method is useful for producing vehicle parts from a composite material having natural lignocellulosic fibers with reduced volatile organic compound odor emissions.

A nonwoven trough and method of construction thereof are provided. The nonwoven trough includes at least one nonwoven wall formed from a mixture of bonded natural cellulosic fibers and thermoplastic fibers. The at least one nonwoven wall extends along a longitudinal axis and has a midsection and opposite end portions. The midsection has a base and a pair of walls extending upwardly from the base to provide the midsection with a generally U-shaped cross-section taken generally transversely to the longitudinal axis. At least one flange extends laterally from the at least one nonwoven wall, wherein the flange is configured for attachment to a vehicle member.

A bio-composite material comprises protein-containing non-wood fibrous biomass comprising at least 6 wt % protein, and a cross-linking agent. The bio-composite material may optionally further contain wood biomass, or non-protein-containing non-wood biomass, and is formable into a bio-composite board to replace wood-based boards for a variety of applications. A bioplastic material comprises a bioadhesive, fibrous biomass and a plastic material, and is formable into a variety of products, such as a cup, using conventional plastic processing techniques. Suitable fibrous biomass may include used coffee grounds and a variety of other biomass. A method of forming a board from a bio-composite material, and a method of manufacturing a bioplastic are also provided.

A liquid-crystalline resin composition is provided, containing: a liquid-crystalline resin; and a fibrous filler formed of crystalline polysaccharides, in which a 5% weight loss temperature of the fibrous filler is 280 C. or higher.

The present invention relates to a process for producing a fiber-foam composite (FSV1), wherein a first fiber material (FM1) is applied to a first foam body (SK1) to give a first structured fiber surface (FO1) to which a second foam body (SK2) is subsequently applied to give the fiber-foam composite (FSV1).
