Hydroentangled Nonwoven Fabric Patents (Class 442/408)
  • Publication number: 20040106348
    Abstract: The present invention is directed to enhancing the cleaning of surfaces by the contact application of a nonwoven fabric having a three-dimensional image imparted therein. The three-dimensional image of the nonwoven fabric induces the formation of lather due to pronounced surface projections that come in contact with the cleaning surface and provide air passageways that are parallel to the plane of the substrate. The imaged nonwoven fabric disclosed herein exhibits low linting qualities thereby reducing the potential of fiber contamination of the cleaned surface and is sufficiently durable that the sample can be used in a brisk manner.

  • Publication number: 20040106342
    Abstract: The present disclosure relates to roll towels made from a nonwoven fabric and treated with a silver-ion containing compound to impart antimicrobial characteristics to the fabric. Specifically, the nonwoven fabric of one preferred embodiment is comprised of composite fibers that are at least partially split into their microdenier elementary components. Such structure provides a greater surface area onto which the silver ions may adhere, thus increasing the amount of surface-available silver. This structure further causes the fabric to be highly absorbent, despite being made of synthetic materials.

    Abstract: A process for producing a non-woven composite fabric by water-jet entangling. First, at least two webs are formed. These at least two webs include at least one spunbonded web or meltblown web. Then, the at least two webs are consolidated by water-jet entangling into a non-woven composite fabric. Compared to a conventional process using thermal bonding to consolidate webs, since the present invention uses water-jet entangling to consolidate webs, the non-woven composite fabric produced from the present invention has superior softness. In addition, the non-woven composite fabric produced from the present invention can be further processed to produce various non-woven composite fabric products such as disposable diapers, sanitary napkins, panty liners, and artificial leather, all with superior softness.

    Abstract: A protective layer embodying the principles of the present invention is configured for protection of automotive surfaces, including specifically, the protection of a truck-bed against wear induced by a truck-bed liner. The protective layer has a substantially planar configuration sized to permit the layer to be positioned generally between an associated truck-bed liner and a truck-bed, whereby the abrasion is significantly reduced. The layer comprises a fibrous nonwoven fabric formed from fibrous and/or filamentary elements, with the fibrous nonwoven fabric exhibiting a sufficiently reduced coefficient of friction and sufficient durability to absorb or distribute abrasive actions, while allowing passage of moisture, thus protecting the automotive surfaces against potentially detrimental environmental conditions.

  • Publication number: 20030114071
    Abstract: A high pulp content nonwoven composite fabric is disclosed. The composite fabric contains 1) from more than about 0 to less than about 30 percent, by weight, of a nonwoven layer of conjugate spun filaments, the filaments containing at least one low-softening point component and at least one high-softening point component and having at least some exterior surfaces of the filaments composed of at least one low-softening point component; 2) more than about 70 percent, by weight, of pulp fibers; and 3) regions in which the low-softening point component at the exterior surfaces of the filaments is fused to at least a portion of the fibrous component. This high pulp content composite nonwoven fabric may be used as a heavy duty wiper or as a fluid distribution material, cover material, and/or absorbent material in an absorbent personal care product. Also disclosed is a method of making the high pulp content nonwoven composite fabric.

  • Publication number: 20030101558
    Abstract: A method for hydroenhancing fabrics is described. The method uses the force of pressurized liquid passing through elongated orifices and impinging on the fabric. The pressurized liquid exits in a coherent or columnar fashion from elongated orifices that are generally rectangular or linear in shape. The elongated orifices can be arranged so as to produce various effects on a web of fabric, including striping, graduated shading and seer-suckering. The elongated orifices also facilitate the hydroenhancement of high-warp-count fabrics without streak or moire effects. Liquid filtration can be relaxed without clogging the orifices, because the elongated orifices permit larger solid objects to pass. The use of elongated orifices also enhances the energy efficiency of the hydroenhancement process.

  • Patent number: 6562740
    Abstract: A shrinkable protective material includes a non-woven fabric bonded to a shrinkable film by an adhesive that is applied to the film in a pre-determined pattern. Upon shrinking, the non-woven 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 bonded portions of the non-woven fabric.

  • Publication number: 20030087575
    Abstract: The present invention relates to a method of creating a textured nonwoven fabric for apparel and home fashions applications, wherein the nonwoven fabric becomes aesthetically altered upon laundering. Once laundered during manufacture, the nonwoven fabric exhibits a permanent distressed appearance that becomes an integral part of the fabric. Subsequent to laundering, the fabric can be formed into a roll for shipment and storage. The distressed appearance of the nonwoven fabric is best described by comparing the laundered fabric to an elephant's skin.
