Abstract:
In an embodiment, the present invention provides a sound-absorbing textile composite having a flow resistance of from 250 Ns/m3 to 5000 Ns/m3, including: a) at least one open-pore support layer including coarse staple fibers having a titer of from 3 dtex to 17 dtex and fine staple fibers having a titer of from 0.3 dtex to 2.9 dtex as scaffold fibers; and b) a flow layer arranged on the support layer, which flow layer includes a microporous foam layer.
