Various embodiments of the present invention provide an elongate hydroentangling jet strip spaced apart from the fabric material and extending substantially across a width of the fabric perpendicular to the processing direction. The strip defines a first row of orifices, each having a first diameter. The first plurality of orifices is spaced apart along a width of the elongate strip. The strip further defines a second plurality of orifices disposed downstream from the first plurality of orifices in the processing direction and offset therefrom along the width of the elongate strip. The second plurality of orifices each define a second diameter smaller than the first diameter such that fluid streams generated thereby impart a correspondingly smaller impact force on the fabric material than fluid streams generated by the first plurality of orifices.

  • Publication number: 20080311816
    Abstract: The invention relates to a method and an apparatus for strengthening a running non-woven web. For this purpose, the non-woven web is penetrated by a plurality of fluid streams. In order to create a surface structure, the fluid streams are generated by a movable nozzle beam, which is guided back and forth at a defined amplitude substantially transversely to the running direction of the non-woven web. In order to obtain enough flexibility and a sufficient volume in the non-woven web in spite of the strengthening effect, the amplitude for moving the fluid streams back and forth is selected in such a way according to the invention that the points of impact created in the non-woven web by adjacent fluid streams do not intersect an imaginary separating line in the running direction. To this avail, the amplitude of the back and forth movement of the nozzle beam is adjusted so as to be smaller than half the distance between two nozzle outlets disposed next to each other in the row.

  • Patent number: 7380317
    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.

  • Patent number: 7356892
    Abstract: Water needling is used to constantly subject the entire surface of a width of a goods line to water jets. However, it is also advantageous for units of commodity goods that are to be consolidated and optionally, if a cover nonwoven supporting these goods only needs to be consolidated around them or if a cover nonwoven is to be bonded around the goods. All possible patterns, such as line or strip consolidation, are advantageous. This is made possible by the invention, which provides for measures which specifically control, e.g. partially impede and/or interrupt the flow of the water jets from a water beam. This can occur by means of cover panels which advance with the line, supported by a screen or by means of a screen alone. Individually movable, computer-controlled nozzles are also advantageous for partial consolidation.

  • Patent number: 7350279
    Abstract: A drum for processing nonwovens has a perforated lateral surface and an interior divided into first and second compartments, respectively associated with first and second lateral surface portions of the drum. A partial vacuum in each of the compartments aspirates and secures a tangentially-engaged nonwoven preform against the lateral surface of the drum for further processing. The drum may be incorporated in a production unit or installation including a spunbond tower for spinning filaments to form the nonwoven preform for tangential delivery to the drum. The resulting nonwoven may thereby be provided with uniform properties.

  • Patent number: 7337512
    Abstract: A hydrodynamic needling apparatus for use on a textile web moving in a longitudinal web-travel direction has a first array of needle-jet orifices emitting respective needle-jet sprays extending in the travel direction between the respective orifices and the web, the array extending transversely across a full transverse width of the web at a substantially constant spacing therefrom with the sprays forming an angle greater than 0° and less than 90° with the web-travel direction. There is a similar second array of needle-jet orifices, but with it the orifices are directed at the same angle but oppositely to the sprays of the first array. Thus the sprays of the first array are directed to one side and the sprays of the second array to an opposite side from the respective arrays.

  • Patent number: 7331090
    Abstract: A non-woven hydroentangled textile is described formed in cross-section with a central area of low mass fiber density surrounded on both sides by areas of higher mass density. Further, a personal cleansing article is described wherein the hydroentangled textile is associated with a personal cleansing composition that includes a lathering surfactant. The composition is deposited onto, impregnated into or at least is partially enclosed by the textile. Also described is a process for producing the textile involving feeding into a hydroentangling unit a loose random assembly of fibers both above and below a fibrous screen modifying textile substrate.

  • Patent number: 7331091
    Abstract: A method of producing a patterned and/or apertured nonwoven material wherein a web of continuous filaments are formed on a forming member, the continuous filaments being free from each other without any thermal or adhesive bonds therebetween, and applying a wetformed fiber dispersion containing natural and/or synthetic or regenerated staple fibers on top of the synthetic filaments. The web is hydroentangled, from the side on which the natural fibers and/or staple fibers are applied, in two subsequent hydroentangling stations and is between the hydroentangling stations transferred from a first hydroentangling wire having a mesh value of at least 20 mesh/cm, to a second hydroentangling wire, having a mesh value of no more than 15 mesh/cm.

  • Patent number: 7310858
    Abstract: The invention relates to a method for generating three-dimensional transparent patterns on a non-woven fabric or similar, whereby, for example, hot air is sucked through openings which form the pattern in the circumferential surface of a drum. The openings are straight or curved gaps instead of conventional holes and together with other openings form the desired pattern. The air or similar, flowing through the gaps, presses the fibres into the gaps and the vacuum on the inner side of the drum sucks said fibres onto the patterning.

  • Patent number: 7310860
    Abstract: A nonwoven product is made by passing a fiber web longitudinally along a treatment path and preconsolidating it at an upstream location along the path. Then the web is fully consolidated by liquid jets downstream of the location at longitudinally spaced and transversely extending discontinuous strips each interrupted at least two break points. The web is then fully consolidated by liquid jets downstream of the location at least two transversely spaced longitudinally extending strips extending a full length of the web and crossing the transverse strips at the break points. Subsequently the web is cut up into pieces along the strips.
