Abstract: The invention relates to a knitted spacer fabric (10) and a method for producing same. The knitted spacer fabric (10) has a first layer (11) formed by stitches (13), a second layer (12) formed by stitches (13), and connection threads (21), which connect the two layers (11, 12) arranged at a distance from one another in a height direction (H). At least one predetermined separation point (22) is formed in each layer, at which point the tensile strength is reduced. The stitches (13) are formed in each case by a thread bundle comprising a first thread (16) and a second thread (17). The threads (16, 17) have different physical and/or chemical properties, for example different melting points, different resistances to alkaline or acidic agents, etc.

Abstract: The invention relates to a knitted spacer fabric (10) comprising two layers (11, 12), which each comprise wales (15) running in a longitudinal direction (L) and courses (16) running in a transverse direction (Q). The two layers (11, 12) are arranged at a distance in a vertical direction (H) and are connected to one another by connection threads (26). In an exemplary embodiment a predetermined separation point (29) is formed in the longitudinal direction (L) between two directly adjacent separation point wales (15a, 15b) in each layer (11, 12). These two separation point wales (15a) are connected by a first thread bundle (20), which comprises fewer threads (22) than a second thread bundle (21). Additionally or alternatively, the wales (15) can comprise float portions (40), in which the threads (22) used for stitch formation outside the float portions (40) do not form any stitches.
