    Abstract: Provided herein is a non-stratified, or homogeneous, non-woven composite having (a) strength-imparting fibers of a relatively high denier and (b) binder fibers of a lower denier that adhere the composite together and that form a smooth, stiff skin on the outer surfaces of the composite. In one instance, the strength-imparting fibers are staple fibers and the binder fibers are bicomponent fibers having a low melt component. In a variation, the composite also contains a small percentage by weight (that is, less than 20%) of flame retardant fibers that impart flame resistant properties to the composite. Preferably, all of the fibers are comprised of the same polymeric material (e.g., polyester), so that the composite is recyclable. The resulting composite exhibits excellent flame retardance, strength, and stiffness, as well as having a smooth surface for attachment of a decorative fabric or other material. A process for manufacturing such composites is also provided.

  • Patent number: 7759267
    Abstract: A multi-layered fiber reinforced sheet for automotive vehicle interior structural components includes, in an exemplary embodiment, a permeable fiber reinforced thermoplastic core layer having a first surface and a second surface. The core layer includes a plurality of reinforcing fibers bonded together with a thermoplastic resin, and has a density of about 0.1 gm/cc to about 1.8 gm/cc. The multi-layered fiber reinforced sheet also includes at least one first reinforcing skin applied to the first surface of the core layer, and at least one second reinforcing skin applied to the second surface of the core layer. Each first and second reinforcing skin includes a matrix of reinforcing fibers and a thermoplastic resin wherein the matrix of reinforcing fibers applied to the first surface are arranged in a bi-directional orientation and the matrix of reinforcing fibers applied to the second surface are arranged in a bi-directional orientation.

  • Patent number: 7745356
    Abstract: The present invention is generally directed to adhesive compositions comprising selected ratios of crystalline and amorphous polymers. In some versions of the invention, polymers capable of existing in different configurations (e.g., a polymer such as polypropylene which can exist in an atactic, syndiotactic. or isotactic configuration) are used to prepare adhesives of the present invention. As an example, a selected amount of isotactic polypropylene is blended with a selected amount of atactic polypropylene to prepare an adhesive composition having one or more performance properties (e.g., bond strength) that are superior to the performance properties of a conventional hot-melt adhesive. The adhesive compositions of the present invention are suitable for use in the preparation of laminated disposable absorbent products.

  • Patent number: 7741235
    Abstract: A composite sheet that has a low basis weight and can inhibit adhesives from flowing out is provided. The composite sheet 1 according to the present invention is formed by bonding a stretchable nonwoven fabric 2 and a non-stretchable nonwoven fabric 3 to each other with adhesives 4. The stretchable nonwoven fabric 2 in an extended state is bonded to the non-stretchable sheet. The stretchable nonwoven fabric 2 has a plurality of strip-shaped non-dense regions 21 and a plurality of strip-shaped dense regions 22 formed on both its surfaces alternately and alternately in the transverse direction such that the dense regions 22 on one of the surfaces and the dense regions 22 on the other surface are not overlapped with each other. The stretchable nonwoven fabric 2 includes thermoplastic fibers that have been stretched at least partially and elastomer fibers.
