  • Patent number: 5736214
    Abstract: A laminated assembly forming the female, loop portion of a self-gripping hook-and-loop fastener. The assembly includes a light-weight, open, mechanically fragile and dimensionally unstable knitted fabric adhered in a flat condition onto a support member, the knitted fabric including interknitted warp and weft yarns, and a multitude of loops having feet cooperating with the warp and weft yarns and a pair of elongate legs extending from the feet and forming a free loop top remote from the feet. The loops are sized in relation to the spacing of the warp and weft yarns of the fabric so that at least one of the two legs of the loop intersects at least one of the warp or weft yarns in spaced-apart relation from the foot of the at least one leg so that each of the loops bears on at least one warp or weft yarn to form an overlapping zone where the loop does not adhere to the support member, thus maintaining the self-gripping ability of the loops.

  • Patent number: 5733822
    Abstract: The present invention provides composite nonwoven fabric laminates and processes for producing such. The fabric is comprised of a web of thermoplastic filaments laminated to at least one other web. Preferably, the filaments are spunbonded continuous polyolefin filaments which have an oxidatively degraded outer sheath portion to promote better interfilamentary bonding and improved fabric laminate strength. In a preferred embodiment, two outer nonwoven webs comprise oxidatively degraded spunbonded filaments and are positioned around and laminated to a web of meltblown microfibers thus forming an spunbond/meltblown/spunbond fabric. Additionally, a stretch compatible fabric may be formed in which a web of oxidatively degraded filaments is laminated to an elastic web. The fabrics of the invention may be advantageously used in numerous applications such as medical garments and disposable adsorbent products.

  • Patent number: 5728448
    Abstract: In a reflective warp-knit tape, a narrow-width warp-knit tape is knitted of chain-stitch yarns, which form loops along longitudinal wales of the warp-knit tape, and weft inlaid yarns. And a reflective film is knitted in the warp-knit tape at a selected interwale space by the weft inlaid yarns and additional weft inlaid yarns. A heat-melting film also is knitted in the warp-knit tape at another selected interwale space by the weft inlaid yarns. Alternatively, the heat-melting film may be substituted by heat-melting yarns inlaid in the wales. In another alternative form, all the knitting yarns of the warp-knit tape may be thermoplastic resin monofilament yarns so that the light-reflecting function of the tape can be improved.

  • Patent number: 5720832
    Abstract: A method of making a non-woven web of melt blown polymeric fibers wherein the melt blown fibers have particles introduced into the stream of microfibers after the microfibers have been extruded. If the particles are of super absorbent material they are distributed substantially individually and spaced throughout the web and provide effective results when used for example in a sanitary napkin, diaper or incontinence pad. If the particles are for example, clay, calcium carbonate, kaolin chalk or the like, then a wiper product made from the web has improved wiping properties.

  • Patent number: 5716686
    Abstract: A quantity of fluid resin material is rendered into a flowable state without the use of solvents. The fabric then is beaded with at least one elongate bead of the flowable resin, wherein at least a portion of bead remains on the surface of the fabric to tackify the fabric and facilitate lay-up of the beaded fabric in the composite molding process. The fabric then is laid-up into a molding apparatus, wherein the bead adheres to surfaces in the molding apparatus and assists in positioning of the fabric therein. A further quantity of resin is disposed or injected under pressure into the molding apparatus and into contact with the fabric and contours of the mold. The resin then is cured to form the composite body.
