  • Patent number: 7550196
    Abstract: Disclosed is a method of producing an automobile interior material or construction sheet with excellent processability, and its product made therefrom. More particularly, a method comprises by carding short fibers wherein short fibers are mixed with polypropylene fibers and polyethylene fibers in a mixing ratio of 3 to 7:7 to 3, on one side or both sides of a foamed layer produced by foaming any one selected from the group consisting of polypropylene chips, polyethylene chips, polyurethane chips, and expanded polystyrene chips; setting the short fibers with a shape of a truss in the foamed layer by interlacing the short fibers through a needle punching process; and thermally forming the short fiber layer(s) on the foamed layer by heating the portions of the short fibers exposed on the outside the foamed layer to 120 to 250° C. and pressing thereby melting, cooling and hardening the fused portions of the short fibers.

    Abstract: The subject matter disclosed herein relates generally to the production of a predetermined ratio of multicomponent fibers in combination with monocomponent fibers or other multicomponent fibers, preferably through a spunbonding process. After extrusion, these fibers can produce a fiber network that is subsequently bonded to produce a nonwoven fabric comprising multiple types of fibers. The multicomponent fibers within the network may be processed to remove one component by dissolution or to split the individual components into separate fibers. As a result, the fabric will be comprised of fibers with a range of diameters (micro- or nano-denier fibers as well as higher denier fibers) such that the fibers will not pack as tightly as in a homogeneous nonwoven fabric produced from one type of monocomponent or multicomponent fiber. The present invention additionally relates to methods for producing nonwoven fabrics with increased loft, breathability, strength, compressive properties, and filtration efficiency.

  • Patent number: 7435694
    Abstract: A fibrous nonwoven mat particularly suited for hiding the color of a substrate when the mat is bonded to the substrate is made by forming a web of fibers from a wet fibrous slurry, saturating the mat with a resinous binder containing 1-20 weight percent of a paper coating material, removing excess binder from the mat to produce a mat having a resin binder content of 5-25 weight percent and drying the mat. The mat has high hiding power for substrates like board or blanket of fiber glass insulation and other colored materials.

  • Publication number: 20080248707
    Abstract: The invention is based on the object of providing armoring that is lightweight and exhibits a denser microstructure that is improved as against ceramic composite materials. To this end, armoring against high dynamic impulsive loads is provided that comprises a composite material having at least two phases, the first phase forming a matrix for the second phase, and the first phase being a glass or a glass ceramic, and the second phase being embedded and distributed in the form of particles and/or fibers in the matrix formed by the material of the first phase.

  • Publication number: 20080241301
    Abstract: The invention concerns a forming head for an apparatus for the production of a non-woven fabric by depositing fibres on a conveyor belt, comprising a fibre feeder which opens into a fibre processing chamber and which has a lower deposit opening for the delivery of fibres, wherein arranged in the fibre processing chamber are interengaging needle rollers with longitudinal axes oriented in mutually parallel relationship, which can rotate about their respective longitudinal axis, and the interengaging needle rollers enclose an inner chamber and are arranged with respect to the fibre feeder and the deposit opening in such a way that fibres fed to the forming head in operation enter the inner chamber by passing through between interengaging needle rollers and leave the inner chamber also by passing through between interengaging needle rollers.

  • Publication number: 20080233825
    Abstract: A composite sheet material including substantially randomly oriented high modulus fibrous material and a nonwoven web of thermoplastic fibrous material is disclosed. The composite sheet material can further include a substantially fluid impervious layer. The resultant composite sheet material can exhibit isotropic physical properties. The isotropic nature of the product can in turn improve the dimensional stability of the product, which can be useful for applications subject to multidirectional stresses, such as roofing membranes exposed to temperature variances.

  • Patent number: 7425517
    Abstract: The present invention provides a nonwoven web or laminate having at least one surface with abrasion resistance and a low degree of free fibers on the surface. Also provided is a lofty nonwoven web laminate from multicomponent fibers having at least one surface with improved abrasion resistance and reduced fuzziness over other multicomponent fiber nonwoven webs. This nonwoven webs and laminate can be used where nonwoven webs and laminates are currently used, but are particularly suitable as a filter media. Also described is a method for producing a nonwoven web having at least one abrasion resistant surface. The process includes using a liner material between the forming surface and the forming nonwoven web, wherein the liner is removed after the nonwoven web is bonded. Removing the liner exposes the abrasion resistant surface of the nonwoven web or laminate.
