Abstract: An apparatus for making a spunbond nonwoven laminate having a plurality of spunbond nonwoven layers has a row extending in a travel direction of two, three, or four spinning beams each emitting a multiplicity of multicomponent crimped continuous filaments with the filaments of each beam having a degree of crimp different from that of the filaments of each of the other beams. Respective extruders supply each beam with the components of the respective filaments and respective supply units feed each of the extruders with the respective components. The rate at which the components are supplied to the extruders is adjusted for varying the proportions of the components in each filament. A conveyor extends in the direction below the beams and receives the filaments as respective layers from the respective beams.

Abstract: 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: Method for producing a fibrous web exclusively from cellulose fibers of natural origin, comprising the following procedural steps: forming an essentially uniformly thick, dry fiber layer from loose fibers having a low moisture content, pressing and embossing the fiber layer to obtain a fibrous web and forming an embossed pattern, moistening the fibrous web with a water-latex mixture having a high water concentration (75 to 99% by weight of water) and precipitating the latex in a drying process while the fibers are bonded inside and outside the fiber bond zones.
