  • Patent number: 9562306
    Abstract: A fabric structure (1) having a cellular construction. The fabric structure comprises at least one base layer (6) consisting of warp threads (10), at least one top layer (7) consisting of warp threads (11) and weft threads (2) placed in between, wherein the fabric structure (1) is formed by a multiplicity of three-dimensional cells (3, 9) and the height (8) of each individual cell (3, 9) is defined by the spacing (8) between two warp threads (10, 11), located above the other in height direction z, in adjacent layers (6, 7), the length (12) of the cell (3, 9) is defined by the spacing (12) between two warp threads (10) or (11) adjacent in the weft direction x, in one layer (6, 7) and the width (13, 14) of a cell (3, 9) is defined by the extent (13) of the weft thread course in the warp direction y and/or the spacing (14) between the two weft threads (2) that are opposite in the warp direction y and adjacent to the particular cell (9).

  • Publication number: 20150368835
    Abstract: The invention relates to a fabric structure having a cellular construction including at least one base layer of warp threads, at least one top layer of warp threads and weft threads placed in between, and formed by a multiplicity of three-dimensional cells having a height, length and width dimension Each weft thread extends at least regionally in the fabric structure in a dimensionally stable and three-dimensional manner and winds in the weft direction x about this axis an imaginary, three-dimensional elongate hollow body, extending through the cells, having any desired end face. The weft threads intersect the warp threads such that the weft threads and warp threads retain one another and the fabric structure is self-supporting.

  • Patent number: 7763272
    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.

  • Publication number: 20010023008
    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.

  • Patent number: 6244077
    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.
