Abstract:
A laminate has first and second spunbonded nonwoven layers at least one of which comprises or consists essentially of crimped continuous filaments that are bicomponent filaments having a first component based on polypropylene and a second component based on polypropylene. A specific density ρ (g/cm3) of the spunbonded nonwoven laminate depending on the surface density of the spunbonded nonwoven laminate lies below a density limit ρG defined by the following equation:
ρG=9 cm−1×surface density g/cm2+0.0393 g/cm3.
ρG=9 cm−1×surface density g/cm2+0.0393 g/cm3.
