A spunbond nonwoven laminate has a plurality of stacked spunbond nonwoven layers, namely at least two and at most four spunbond nonwoven layers that have crimped continuous filaments or consist of crimped continuous filaments. The degree of crimping of the filaments is different in each of these spunbond nonwoven layers, and each of the crimped filaments of the spunbond nonwoven layers has a crimp with at least two, preferably at least three, and more preferably with at least four loops per centimeter of length. The crimped filaments of the spunbond nonwoven layers are multicomponent filaments, particularly bicomponent filaments, with a first plastic component and a second plastic component present in the respective filament in a proportion of at least 10 wt %.

Abstract
A laminate is made by first non-crimping or low-crimping continuous filaments to form a first spunbond layer and preconsolidating the first spunbond layer with a heated or calendering roller. Then continuous filaments with a greater crimp than the continuous filaments of the first spunbond layer are deposited as a second spunbond layer over the first spunbond layer to create a two-layer structure. Finally, the two-layer structure of the first and second spunbond layers is consolidated such that a total thickness of the laminate is 0.15 to 3 mm, preferably 0.2 mm to 2.5 mm and especially 0.2 mm to 2 mm.
