Method of making a spunbond nonwoven laminate

An apparatus for making a spunbond nonwoven laminate having a plurality of spunbond nonwoven layers, the apparatus comprising:

• 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 equal to at least three loops per centimeter of length and different from that of the filaments of each of the other beams;
• respective extruders supplying each beam with the components of the respective filaments each of a first plastic component that consists of only one first plastic and a second plastic component that is mixture of a second plastic and a third plastic;
• respective supply units feeding each of the extruders with the respective components with each of the two first and second plastic components being present in the multicomponent filaments in a proportion of at least 10 wt %, a mass of the third plastic relative to a mass of all the multicomponent filaments of the laminate being less than 25 wt %, and a molecular weight distribution of the third plastic greater than a molecular weight distribution of the first plastic and greater than a molecular weight distribution of the second plastic;
• means for varying the rate at which the components are supplied to the extruders for varying the proportions of the components in each filament;
• and
• a conveyor extending in the direction below the beams and receiving the filaments as respective layers from the respective beams.
