The fabric comprises a first weave (1) including weft threads (4) and warp threads (3), and a second weave (2) which is interconnected with the first weave, said second weave comprising coarser weft threads (6), which interweave with warp threads (5) arranged in groups of at least two threads. The warp threads (5) of each group run in parallel with each other and weave alike with the weft threads (6) of the second weave (2).
