Fleece material of polymer filaments consolidated by needling, adhesion, meshing, over-sewing or high pressure jetting, has stacked layer construction

摘要

The cross section of the fleece (1) comprises planar, horizontally-stacked layers of filament pile (2), with matted filament arrangement, formed from filament nap (8). Each layer (2) has a weight of at least 5 g/m2> and at most 50 g/m2>. Three to thirty filament layers are stacked in the fleece cross section. Additional fibrous nap (4) layers (17) intervene. These are of the same or different polymers. The filament naps (8) and the fibrous nap (4) have the same, or different filament- or fiber units. In the fleece material cross section, between the filament and fiber layers, flat textile or non-textile functional layers (6) are located. The functional layer (6) comprises scattered or flowing functional agents (7). An independent claim is included for the corresponding method of fleece manufacture.
