Zusammenfassung: | A laminate is made of a spunbonded nonwoven laminate, by first making first and second spunbonded nonwoven layers of which at least one has crimped bicomponent filaments having a first component based on polypropylene and a second component based on polypropylene. Then at least one spunbonded nonwoven layer is preconsolidated, and finally the first and second spunbonded nonwoven layers are finally consolidated into the spunbonded nonwoven laminate by at least one calender roller such that the laminate has a specific density dependent on its surface density and below a density limit ρG according to the equationρG=9cm-1Hsurfacedensityg/cm2+0.0393g/cm3. |
