An apparatus for the production of needle punched nonwovens makes it possible to introduce different materials via the nonwoven thickness and/or nonwoven width into the individual layers during their production.

A process and an installation for producing a yarn in accordance with an airjet-spinning method. A carded fibre sliver is subjected to more than three-fold drawing without levelling at a carding machine and deposited in a can (C). At least nine fibre slivers are fed draftfree from cans (C) to a draw frame and subjected to at least 8.5-fold drawing to form a fibre sliver and deposited in a can (C1). The fibre sliver in the cans (C1) is then fed to a spinning station of an airjet-spinning machine.

A carding apparatus (2) and a carding method for producing a card web (12) are based on the carding apparatus (2) including a web forming device (5) for creating a preliminary web (3), followed by a web layering apparatus (7) which is followed by a card (6), and a controllable or adjustable profiling device (8). The profiling device (8) precedes or is associated with the web layering apparatus (7). The profiling device (8) is used for profiling the preliminary web (3) in order to preventively compensate for peripheral bulges in the card web (12) discharged by the card (6).

A process of manufacturing a resilient, fibrous, piled woven fabric includes moving a resilient, fibrous woven fabric through a platform type carding machine including at least one first roller having a rough surface, at least one second roller having a surface formed of needles, and at least one third roller having a fine surface. One surface of the woven fabric passes and contacts the first roller so that fibers on one surface of the woven fabric are cut, one surface of the woven fabric passes and contacts the second roller so that the fibers on one surface of the woven fabric are broken to form a layer of uneven pile structure thereon, and one surface of the woven fabric passes and contacts the at least one third roller so that the layer of uneven pile structure is combed out and smoothed to finish a resilient, fibrous, piled woven fabric.

The present invention is directed to plant fiber-reinforced biocomposite thermoplastic and/or resin compositions and a method for reinforcing thermoplastic resins. The present invention provides a use for the cellulose portion of a plant material, which is the portion left over after processing the selected plant materials to separate the cellulose in a mechanical process that does not damage the internal molecular structure of the cellulose fraction, enabling the cellulose fraction to chemically bond with the thermoplastic resin to enhance the reinforcement of the resin or thermoplastic biocomposite composition.
