Definitions

  • the invention relates to a nonwoven with densified consolidation points or welding spots or the like. and fluffy or loose areas in between.
  • Such nonwovens are known in numerous variations. They are produced from fiber structures which are solidified at certain points with the aid of pairs of rollers under the action of heat and / or solvents, the rollers generally having knobs which protrude from their surface.
  • a smooth roller is combined with a roller that has knobs, so that one side of the fleece is fully acted upon by such a roller when individual points are solidified, and the fleece on this side is thus somewhat solidified.
  • the fleece according to the invention is characterized in that adjacent consolidation points are offset in height from one another and the fluffy areas bridge the height differences of the consolidation points.
  • the overall result is a fleece of relatively great thickness, which therefore has fibrous, loose areas which have not been impaired by the consolidation process, the fleece being able to be thicker than before, in some cases even after processing, due to the height offset of the consolidation points.
  • the welding points or consolidation points are arranged in two approximately parallel planes offset from one another in height in each case directly adjacent consolidation points of one level have a depression between them, the bottom of which represents a consolidation point in the parallel plane.
  • a fleece of defined thickness is obtained with good stabilization at the consolidation points and still great looseness in between.
  • Half of the number of consolidation points can be in one level and the second half in the other level. This can be achieved practically with two fleece-processing rollers, the knobs of which are offset from one another in such a way that the knobs of one roller fit and engage in the spaces between the knobs of the other rollers, but maintain a distance between their flanks within which the Fleece remains unprocessed.
  • Another advantageous feature of the nonwoven according to the invention can be that the extent of the area of the consolidation points is smaller than the space delimited in one level by consolidation points and the fluffy areas can run obliquely from the consolidation points on one level to those on the other level.
  • the flexibility of such a fleece after its completion across its main surface is thus significantly promoted by these inclined non-consolidated areas, because not only the dimension originally running across the fibers is available as a compression area, but also the distance between the different areas Leveling points arranged.
  • the welding points or consolidation points each have a continuation or a transition into the oblique one have fluffy areas and are each approximately cap-shaped. This means that the very last ends of the fluffy areas are already solidified in their oblique course, which can be realized very easily if the knobs are heated appropriately, so that solidification is also effected somewhat beyond the edge of the knob surface where the fleece is still relatively tight against such a knob.
  • a combination of the features and measures described above results in a nonwoven which can have a greater thickness than if it were consolidated between touching knobs or if the bond between a smooth roller and one with knobs would take place.
  • a relatively firm and resilient outermost surface of such a fleece results at the same time, compared to which the loose and fluffy and absorbent areas are offset somewhat inward, which also affects the shelf life and transport as well as the service life of a such fleece benefited.
  • a fleece 1 is provided with compressed fastening points 2 or welding spots and fluffy or loose areas 3 located between them. 3, the consolidation points 2 and the fluffy areas 3 lie practically in one plane, so that such a nonwoven is relatively thin after its completion, the nonwoven according to the invention according to FIG. 3 provides that adjacent to each other Solidification points 2 are offset in height from each other and the fluffy areas 3 bridge the height differences of these consolidation points 2.
  • FIGS. 2 and 3 clearly shows that a fleece 1 of considerable thickness can thereby be produced, which can therefore also have a correspondingly good cushioning or suction effect.
  • the consolidation points 2 each lie on the opposite top sides and thus protect the fleece 1.
  • Fig. 2 makes it clear that the welding points or consolidation points 2 are arranged in two mutually vertically offset, approximately parallel planes. In each case adjacent consolidation points 2 of one level have between them a depression 4, the bottom of which represents or has a consolidation point 2 in the parallel plane. In this way it follows that half of the number of consolidation points 2 in the one level and the second half is on the other level.
  • the extent of the area of the consolidation points 2 is smaller than the space delimited in each plane by such consolidation points 2 and the fluffy areas 3 run obliquely from the consolidation points 2 on one level to those on the other level. In this way, they can absorb much larger deformation paths, so that the softness and suppleness of the fleece 1 according to the invention is considerably increased compared to a conventional fleece according to FIG. 3.
  • Another advantage of this arrangement and shape of the fleece is that at a pressure approximately perpendicular to the planes in which the consolidation points 2 are located, the loose and fluffy areas 3 are even compressed and possibly increased in their actual thickness, so that their absorbency can even increase somewhat.
  • stiffening or welding points 2 offset from one another in height and the fluffy areas located between them is that this Fleece can be brought into this form in a single operation, namely during its solidification and spot welding, and subsequent embossing of the fleece is avoided, in which there is a risk that fluffy areas in particular could be pressed and buckled and would thus lose their volume.
