Embodiment Construction

[0083] figure 1A device according to the invention for producing a spunbond nonwoven laminate S is shown, which preferably and in this example has three spunbond nonwoven layers L1, L2 and L3. Corresponding to the three spunbonded nonwoven layers L1, L2 and L3, three spinneret beams or spinneret plates 1 are arranged, from which spinneret beams, preferably and in this example, the bicomponent Filaments in filament form 3. After passing through the diffuser 11 , the filaments 3 of each spunbond nonwoven layer L1 , L2 and L3 are laid down on a laying screen 13 to form a spunbond nonwoven layer L1 , L2 and L3 . Here, each spunbond nonwoven layer L1 , L2 , L3 is compacted by a pair of compaction rollers 14 . Subsequently, the finished three-layer spunbond nonwoven laminate S is transferred by a laying screen 13 to a calender 17 consisting of two calender rolls 18 , 19 . figure 1 An enlarged detail of the transfer of the spunbond nonwoven laminate S from the laying screen bel...

Abstract

The invention relates to a spunbond nonwoven laminate which is provided with a plurality of laminated spunbond nonwoven layers. At least two and at most four spunbond nonwoven layers have crimped continuous filaments. A degree of crimping of the filaments in each of the spunbond nonwoven layers is different from a degree of crimping in each of the other spunbond nonwoven layers and each of the crimped filaments of the spunbond nonwoven layers has a crimp with at least two loops per centimeter of length. The crimped filaments of the spunbond nonwoven layers are multicomponent filaments each having at least one first plastic component and at least one second plastic component. In addition, the invention also relates to a method and device for manufacturing the spunbond nonwoven laminate which is provided with a plurality of laminated spunbond nonwoven layers.

Description

technical field [0001] The present invention relates to a spunbond nonwoven laminate having a plurality of spunbond nonwoven layers arranged one above the other, wherein the spunbond nonwoven layers have crimped continuous filaments, or consist of crimped continuous filaments production. Furthermore, the invention relates to a method and a device for producing such a spunbond nonwoven laminate. In the context of the present invention, a spunbond nonwoven is in particular a spunbond nonwoven produced according to the spunbond process. Due to their almost infinite length, continuous filaments are distinguished from staple fibers which have much smaller lengths, eg 10 mm to 60 mm. The continuous filaments used within the scope of the present invention are in particular continuous filaments made of thermoplastics. Background technique [0002] In practice, spunbonded nonwoven laminates of the above-mentioned type are known essentially in different embodiments. The problem th...
