Abstract

The invention relates to a nonwoven composite fabric comprising at least one layer A and at least one layer B, wherein at least one surface layer of the nonwoven composite fabric is formed by layer A, wherein layer A is a nonwoven fabric, and wherein a) layer A comprises first fibers, preferably first filaments, being first melt-spun composite fibers, preferably first melt-spun composite filaments, which are splitted to at least some extent to produce first elementary fibers, preferably first elementary filaments, having an average titer of at most 0.2 dtex, wherein the amount of the first fibers is 10 wt.% to 35 wt.% based on the total weight of the nonwoven fabric; b) layer B comprises b1) second fibers, preferably second filaments, with an average titer from 0.25 to 10 dtex, preferably 0.25 to 3.5 dtex, wherein the amount of the second fibers is 65 wt.% to 90 wt.% based on the total weight of the nonwoven fabric, or b2) a woven grid comprising yarns having an average titer from 500 dtex to 2200 dtex, preferably from 800 dtex to 2200 dtex, wherein the amount of the yarns is 20 wt.% to 90 wt.%, preferably 65 wt.% to 90 wt.% based on the total weight of the nonwoven fabric or b3) second fibers, preferably second filaments, with an average titer from 0.25 to 10 dtex and a woven grid comprising yarns having an average titer from 500 dtex to 2200 dtex, wherein the combined amount of the second fibers and of the yarns is 65 wt.% to 90 wt.% based on the total weight of the nonwoven fabric.
