Abstract: A scaffold for tissue culture and cell culture and for producing implant materials, in particular bone, cartilage or skin replacements or extra-corporal organ replacements or for other applications in medicine or biotechnology is made of biocompatible materials. It has at least one base material which is electrostatically flocked with fibers on at least one side. Through the electrostatic flocking the fibers are arranged almost perpendicularly on the surface of the base material and exhibits a high fiber pull-out resistance. The scaffold provides an elastic growth lattice, which is stable against compression, for cell colonization in vitro or the ingrowth of cells in vivo. Implants or implant materials can be produced with the scaffold.

Abstract: Multilayered sheet insulating material for heat insulation and sound proofing having at least two separation layers made of flexible material, such as sheets, non-woven fabric, paper or the like, and spacer elements between the separation layers. The spacer elements are formed by spacer fibers which are oriented perpendicular to the separation layers, and at least one end of the spacer fibers is linked, e.g., by adhesive, to a separation layer. The sheet insulating material also includes supporting fibers arranged between the separation layers and proximate the spacer fibers for supporting the spacer fibers. The sheet insulating material has very good insulating properties, a particularly low weight and high flexibility.

Abstract: A multilayer knitted structure includes two knitted webs which are interconnected by a third thread system. The two knitted webs are held together by at least one bundle of warp threads, and is suited for use in producing semi-finished structures for fiber composites. The thickness of the multilayer knitted structure can be increased by further warp thread bundles and additional weft threads. The warp and weft threads are advantageously configured to run according to the stress applied, for example, in the fiber composite.

Abstract: The invention is directed to a process and a device for the production of textile net-like fabrics by various bonding processes, e.g., the warp knitting process or stitch bonding process.

Abstract: In a textile machine including needles for forming a plurality of warp yarns into stitches and a guide bar for guiding the warp yarns to the needles, the guide bar is constructed to lay warp yarns in patterns without moving the entire guide bar by providing the guide bar with at least one guide block movable relative to a fixed point on the guide bar. Each of the guide blocks includes a respective guide for one or more warp yarns. At least one guide block is connected in a chain configuration to at least one distance altering element, and the distance altering element is controlled to variably alter the distance between the guide block and the fixed point.

Abstract: A non-woven fabric is produced by the transportation of a fiber flow at an angle which is less than 90.degree. to the transport direction of the non-woven fabric to be manufactured, with the feed rate of the fiber flow being controlled, the fibers which are to form a fiber layer being placed next to one another, and with the formed fiber layer being simultaneously, and in the lateral border areas of the fiber layers, being consecutively, combined with the preceding fiber layer, reinforcing the produced non-woven fabric. The angle of the fiber flow to the transport direction of the non-woven fabric to be manufactured is set between 0.degree. and 89.degree.. The controlling of the fiber flow comprises monitoring of the quantity feed rate and/or dissociation of the fiber flow and/or fiber mixing, immediately prior to the formation of a fiber layer.

In order to combine the formed fiber layer with the preceding fiber layer, this is placed adjacent to the formed fiber layer, or placed on at least one formed fiber layer.

Abstract: In order to efficiently irradiate a flowable material with high energy electrons, a hollow body is disposed in a container for the material and the material is caused to flow in the form of a thin layer across a surface of the body from or to the interior of the container while the material flowing across the body surface is irradiated.
