The present invention relates to a suede-like artificial leather with excellent strength and elongation properties. The suede-like artificial leather comprises a composite sheet having polyurethane filled therein, the composite sheet comprising: a non-woven fabric of ultrafine short fibers entangled with each other and having a thickness less than 0.3 denier; and a woven or knitted fabric placed in the non-woven fabric, entangled with the ultrafine short fibers of the non-woven fabric, and having an constant load elongation of 10 to 30% at a load of 8kgf, wherein the tensile strength in longitudinal and lateral directions is 35 to 60kgf/50iιini and the constant load elongation in longitudinal and lateral directions is 8 to 25%. The suede-like artificial leather is useful as materials for vehicles and furniture requiring durability because of its excellent tensile strength and constant load elongation.

A ballistic structure having at least one laminate sheet of a plurality of fiber bundles is disclosed. The laminate sheet has adhesive resin on at least one surface thereof, without substantial penetration of the adhesive resin into the fiber bundles. In embodiments having more than one laminate sheet, the inter-laminate shear strength between the laminate sheets is controlled to control ballistic effectiveness of the ballistic structure.

Abstract A composite nonwoven fabric having latent elasticity is provided having a latently elastic core comprising a first component that includes a thermoplastic elastomer and a second component that includes a single site catalyzed polyolefin, and at least one gatherable facing material laminated to the elastic core. The first and second components may be, for example, in the form of alternating filaments of styrenic block copolymer and single site catalyzed polyolefin or in the form of conjugate filaments having a first section of styrenic block copolymer and a second section of single site catalyzed polyolefin. Also disclosed are methods of making the latently elastic stretch bonded laminates and personal care articles containing the latently elastic stretch bonded laminates.

The present invention is directed to a method of making a laminate nonwoven fabric which entails integration of a continuous filament web with a web of cellulosic fiber material, typically wood pulp. In order to abate loss of cellulosic fiber material during integration by hydroentanglement, the present invention contemplates that the continuous filament web is first subjected to hydroentanglement, with the cellulosic fibrous material thereafter integrated, by hydroentangling, into the partially entangled continuous filament web.
摘要:
A method and apparatus for forming an improved pultruded and clinched Z-axis fiber reinforced composite laminate structure (33). The upper and lower skins (51a, 51b) and the core (22) are pulled automatically through tooling (23) where the skin material is wetted-out with resin and the entire composite laminate (33) 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 (24) 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 (39). Next the preformed composite laminate travels into a pultrusion die (26) where the extended "groupings of fiber filaments" are all bent over above the top skin and below the bottom skin producing a superior clinched Z-axis fiber reinforcement as the composite laminate continues to be pulled, catalyzed, and cured at the back section of the pultrusion die. The composite laminate continues to be pulled by grippers that then feed it into a gantry CNC machine (36, 37) that is synchronous with the pull speed of the grippers (34, 35) and where computerized machining, drilling, and cutting operations take place. This entire method is accomplished automatically without the need for human operators.
摘要:
A laminated panel-type structure (10), particularly suited for vehicle interior applications such as headliners and door panels, has a multiple denier polyester fiber core (12) and randomly oriented structural reinforcing fibers (14, 16) attached and intertwined with the core (12) on opposing major sides of the core. The core (12) of intertwined polyester fibers of differing deniers preferably has relatively large denier fibers on exterior areas of the core and some bicomponent fibers. The laminate structure also has an impervious polymer film (18) with a low melt layer, which retains the reinforcing fibers (14) against one side of the core (12), and a scrim layer (20) attached to said impervious film (18). Next to the reinforcing fiber layer (16) is a polymer web (19) and a cover stock (22). The invention further includes a method of manufacturing the laminated structure.

The invention relates to a composite material, comprising a fiber composite (1) consisting of a plurality of fiber layers (2) embedded in a polymeric matrix, some of which preferably have fiber orientations (2) differing from the fiber orientations of the other fiber layers (2), in addition to a connecting area (4) formed by a reinforcement material (9) that is highly resistant to bearing pressure, wherein a transition area (3) is formed between the fiber composite (1) and the connecting area (4), in which the fiber layers (2) meet with the reinforcement material (9) of the connecting area (4). The invention aims at providing a composite material that is highly resistant to tensile strength and bearing pressure in the connecting area (4). This is achieved in that the connecting area (4) is formed by fiber layers (9) passing from the reinforcement material through the transition area (3) into the connecting area (4) and in that non-continuos fiber layers (2) meet with the corresponding layers (9) from the reinforcement material in the transition area (3) between the continuos fibers layers (2).

The invention relates to a process for manufacturing a band-shaped non-woven product with increased tensile strength longitudinally and/or in the cross direction of the band-shaped product, characterized in that, in the direction in which the tensile strength of the non-woven is to be increased, strengthening wires and/or filaments are applied to it, and joined to the fleece of which the non-woven consists, by application of one of the following techniques, namely needling, hydrolace glueing, or application of heat when the materials of which the non-woven and/or the strengthening wires and/or filaments consist, lend themselves to that.
