    Abstract: A composite textile includes a batting layer, a cushion layer, and a face fabric. The batting layer has high melt temperature and low melt temperature fibers. The cushion layer is needled to the batting layer. The face fabric is bonded to the cushion layer by an adhesive. The face material/cushion layer/batting layer is heat set and rolled onto a roll for use in forming composite parts. The composite textile is more readily recyclable when the batting layer, the cushion layer, the adhesive, and the face material are all formed completely from material of the same chemical nature, such as polyolefin, polyester, or the like.

    Abstract: A method for hydroentangling a nonwoven web to increase the strength and abrasion resistance while maintaining highly desirable hand and drape characteristics. The method provides for carding and cross-lapping synthetic and/or natural fibers so as to form a desired substrate. The substrate is then hydroentangled under relatively low pressure to form a desired spunlace web, and a relatively low amount of a foam adhesive latex binding material is applied to the spunlace web. Thereafter, a force is applied to the foamed spunlace web so as to cause the foamed binding material to fully penetrate the spunlace web from face to back. The resulting hydroentangled (spunlace) nonwoven web provides an enhanced balance of tensile properties, abrasion resistance, and fabric aesthetics.

The rod is first rotated by a motor and then actuated upwardly completely through the thickness of the layer of x-y material by an actuator. A first hollow tube having a z-axis is axially aligned with the aperture in the top surface and a fiber bundle is threaded downwardly through a first hollow tube to a position adjacent its bottom end.

    Abstract: A method and apparatus for forming an improved pultruded and clinched Z-axis fiber reinforced composite laminate structure. The upper and lower skins and the core are pulled automatically through tooling where the skin material is wetted-out with resin and the entire composite laminate is preformed in nearly its final thickness. The preformed composite laminate continues to be pulled into an automatic 3-dimensional Z-axis fiber deposition machine that deposits “groupings of fiber filaments” at multiple locations normal to the plane of the composite laminate structure and cuts each individual grouping such that a extension of each “grouping of fiber filaments” remains above the upper skin and below the lower skin. The preformed composite laminate then continues to be pulled into a secondary wet-out station.

  • Publication number: 20020123289
    Abstract: The present invention relates to an electromagnetically conductive textile fabric comprising conductive fibers arranged to provide a conductivity gradient through its thickness. The fibers may be intrinsically conductive or coated with a conducting material and the gradient can be related to variances in fiber density, fiber diameter (fineness) and fiber conductivity. The fabric can be used to eliminate or reduce electromagnetic interference (EMI) in various applications.

  • Patent number: 6436215
    Abstract: A band element for mounting in the crown portion of a pneumatic tire to provide run flat ability to the tire in the event of loss of air pressure and to provide increased puncture resistance. The band is formed of flat strips of tape having fibers embedded in a resin matrix which are twisted and then pultrated to provide a rectangular cross sectional configuration. The twisted tape is wrapped about a mandrel and forms either the only layer, or the intermediate layer of a composite band in combination with inner and outer layers of flat tape or wound filament fibers, whereby the fibers in the tape extend across the central axis of the band to reduce interlaminar sheer. In another embodiment, a plurality of dimples or depressions are formed in the individual tape layers to extend a plurality of the fibers across the layer boundaries to reduce interlaminar sheer.

  • Patent number: 6405773
    Abstract: A pneumatic tire is reinforced by a thin annular composite band embedded in the crown portion of the tire to enable the tire to resist compressive forces in the tire when in an uninflated condition. The band is formed of a plurality of wound layers of first and second resin coated fiber tows wherein the first tow is formed of fibers twisted at a greater angle than the fibers in the second tow. Layers of the first tow are located adjacent the neutral axis of the band to provide interlaminar shear strength with the tow layers located adjacent the inner and outer surfaces of the band being formed predominately of the second tow to provide a high level circumferential stiffness. The intermediate tow layers are formed of both type of tows to provide a transition zone between the central interlaminar shear strength and the outer circumferential stiffness.

  • Publication number: 20020046800
    Abstract: A hydroentangled nonwoven fabric exhibiting cross-direction extensibility and recovery comprises a nonwoven web of staple length fibers of about 0.8 to 3.0 denier having a basis weight of about 1.0 to 4.0 ounces per square yard. A polymeric binder composition substantially uniformly applied to the nonwoven web imparts desired elasticity to the web, with the fabric exhibiting at least about 50% extensibility in a cross-direction thereof, and at least about 90% recovery in a cross-direction. The nonwoven web may comprise synthetic fibers, natural fibers, and blends thereof, as well as continuous filaments. Patterned hydroentanglement of the web acts to entangle the fibers to provide the fabric with desired performance characteristics. A method of making the nonwoven fabric is disclosed. The nonwoven fabric is particularly suited for use in a mattress pad assembly, as also disclosed herein.

  • Patent number: 6375773
    Abstract: A plant serves as a mean for production of a fibre web of synthetic fibres, such as plastic fibres and absorbent fibres, such as viscose and cellulose fibres. The plant includes a forming head preliminary to lay a homogeneously and smoothly distributed fibre layer on a net shaped wire. Furthermore the plant includes a hydro-entangling section with liquid nozzles with powerful liquid jets to treat the in the forming head formed fibre layer, which consists of both synthetic—and absorbent fibres. The plant also includes an oven subsequently to thermal bond the synthetic fibres with cross bonds in the affected areas. Finally the dried web is winded up in a roller. By the help of the plant according to the invention, by higher production speed than known previously a fibre web can be produced, which is far cheaper, and which has a better and more homogeneous structure than similar conventional fibre webs.
