05 and 3 mm expediently between 0 08 and 1 mm and preferably be formed as monofilaments the binding threads 22 may as polymer based mono or multifilaments have a diameter of less than 0 1 mm a thread cross section that differs from the circular form for example a trilobal thread cross section is also conceivable in such a case the thread diameter can be defined on a surface of rotation which is obtained by a rotation of the thread cross section about its center axis a polymeric material such as pet pa pc pp ptfe pvdf pmaa pan or pe is likewise suitable as thread material for the core threads 18 20 alternatively it is also conceivable to use metal threads glass threads or threads made of inorganic materials the thread material may be transparent or dyed preferably the weft threads consist of a continuous yarn and are introduced if appropriate in combination with a spun thread yarn in the warp combinations with fibrous yarns are also conceivable in order to achieve particular properties such as flame protection in particular for use indoors the fabric can also be treated the thread materials themselves can also be rendered low flammable by the addition.
