    Abstract: The present invention is directed to a nonwoven fabric having a combination of a planar background element and projection elements to form a three-dimensional pattern, and a plurality of durable sub-millimeter orifices that extend at least partially through the depth of the three-dimensional pattern. The three-dimensional image of the non-apertured nonwoven fabric enhances the treatment, cleaning or cleansing performance due to pronounced surface projections that come in contact with the object to be treated or cleaned, and provide air passageways that are parallel to the plane of the substrate. Incorporation of sub-millimeter orifices in the nonwoven fabric, which extend through at least part of the nonwoven fabric, allow for transmission of fluids, as well as applied or embedded chemistries, from one side or surface of the substrate, or from a region internal to the nonwoven fabric, to the side which is in communication with the formed orifice.

  • Patent number: 7074473
    Abstract: A pile carpet after tufting or the like is usually provided on the back with a latex precoat for stabilization and then provided with a foam back or an additional jute fabric. This environmentally hazardous method and the problem of recycling the foam back as well as the latex layer can be avoided If a nonwoven is applied instead to the tufted back of the carpet by water needling. This is possible with water needling in that the solidification of the pile fibers in or on the primary carrier takes place but no nonwoven fibers reach the visible side of the carpet. The back layer to be needled can also be made thicker and mote voluminous. Instead of a carpet, any other pile goods can also be stabilized in this fashion.

  • Publication number: 20040142622
    Abstract: The present invention is directed to nonwoven barrier fabrics, and more specifically, to medical, hygiene and industrial articles comprised of nonwoven compound fabrics with improved barrier to basis weight performance, wherein the improved nonwoven compound fabrics are prepared by forming an intermediate nonwoven construct by supplying a strong and durable substrate layer followed by deposition of a frangible fibrous layer onto the substrate layer thereby providing nonwoven barrier materials. The so formed intermediate construct is subsequently subjected to mechanical energy which induces the frangible fibrous layer to fragment into sub-fibers exhibiting an equivalent denier as the frangible fibrous component, said sub-fibers becoming inter-engaged in the strong and durable substrate layer, thereby providing nonwoven barrier materials exhibit useful barrier performance.

  • Publication number: 20040137816
    Abstract: A shrinkable protective material includes a nonwoven fabric bonded to a shrinkable film by an adhesive that is applied to either the nonwoven fabric or the shrinkable film in a pre-determined pattern. Upon shrinking, the nonwoven fabric separates or releases from the film and forms cushions or pillows holding the film off of the surface being protected. The edge portions of the cushions or pillows act as shock absorbers and deflect over the bonds, thus protecting the surface against the abrasive adhesively bonded portions.

  • Patent number: 6753276
    Abstract: A nonwoven fabric includes a cohesively integrated web of hydrodynamically entangled short-staple or “waste cotton” fibers. A batt of waste cotton fibers is hydrodynamically needled by high-pressure streams of water. The hydrodynamic energy of the streams causes the fibers to cohere and to become mutually entangled, which in turn results in a fabric of sufficient strength to be used for, among other things, a bag for a bulk material and particularly a bag or cover for a cotton bale.
