Each layer grouping has a normalized stiffness of less than about 5 g/g/m2 as tested by a modified ASTM Test Method D6828-02 and contains one or two spike resistant textile layers, an adhesive layer, and one or two knife resistant textile layers. The spike resistant textile layers contain a plurality of interlocked yarns or fibers, where the yarns or fibers have a tenacity of about 8 or more grams per denier and the fiber size is less than ten denier per filament. The knife resistant textile layers contain monoaxially drawn fiber elements, where the fiber elements have an aspect ratio of greater than one and have a size greater than 100 denier per filament. The fiber elements of the knife resistant textile layer are bonded to each other or to the spike resistant layer.

Abstract: A waved mesh tube including multiple parallel first strings spirally extending in a first direction and multiple parallel second strings spirally extending in a second direction. The second strings are laid on the first strings. The mesh tube has continuous circles of waved bending sections arranged along an axis of the mesh tube. The mesh tube is formed with the bending sections so that the wall of the mesh tube has multiple wave crests and wave troughs adjoining each other. The wave troughs define an inner diameter of the mesh tube, while the wave crests define an outer diameter of the mesh tube. Each of the wave crests and the wave troughs has an acute angle. A difference between the inner diameter and the outer diameter is a thickness of the wall of the mesh tube. The wall of the mesh tube is waved and solid and has higher rigidity.

Abstract: A composite sandwich panel a first facing and a second facing over a core layer, the first and second facings having at least one fiberglass layer between an inner and an outer graphite layer.

Abstract: Crimped bath scrubber including at least one blank material extending in a predetermined direction. The blank material is made of multiple first yarns and second yarns by a non-weaving measure. The blank material includes a substrate layer formed of the first yarns and a top layer overlaid on the substrate layer and formed of the second yarns. Corresponding portions of the first and second yarns are connected. The extending direction of the second yarns and the extending direction of the first yarns and the extending direction of the blank material respectively contains predetermined angles. The blank material is formed with multiple upward or downward bent crimped sections. The contained angle of each bent crimped section is less than 90 degrees, whereby the blank material is formed with multiple triangular solid spaces and the blank material is more spongy and fluffy so as to contain more water and bubble therein. The angles of the crimped sections provide better cleaning effect.

Abstract: A composite structure for a protective garment, such as a pair of bunker pants for a firefighter, a bunker coat for a firefighter, or a glove for a firefighter, has a moisture absorber, a moisture barrier covering the moisture absorber, and an outer shell covering the moisture barrier. The moisture absorber has a fibrous matrix incorporating a superabsorbent polymer, as particles or as fibers, and is disposed between an inner cover pervious to moisture and an outer cover. The inner and outer covers may be quilted so as to segregate discrete regions of the fibrous matrix. In one contemplated embodiment, the moisture barrier is affixed to the outer shell so as to have surface-to-surface adhesion between an outer surface of the moisture barrier and an inner surface of the outer shell.

Abstract: A multi-layered composite comprising a protective layer, a retaining layer, a conductive layer and a filler layer intermediate the retainer and conductive layers. The filler layer is impregnated with liquid absorbent particles. A protective layer having specific characteristic for protection against extreme temperatures, physical impacts and the like is specifically disclosed for use in combination with the retainer, filler and conductive layers. The protective layer provides additional protection of the person from catastrophic events such as exposure of a person to fire and/or severe impact such as may be caused by gunfire.

Abstract: A nonwoven primary carpet backing includes thermoplastic polymer filaments or fibers bonded by means of a binder polymer. The backing includes at least a distinguishable thermoplastic woven layer, a distinguishable thermoplastic continuous layer, or a distinguishable nonwoven layer including filaments or fibers bonded by means of a binder polymer, which layer reduces the delamination strength of the backing, measured in accordance with DIN 54310, by at least 30% and preferably by at least 50%, with respect to the same backing without the distinguishable layer. Although the breaking strength of the untufted backing according to the invention is lower than that of untufted backings not including the distinguishable layer, the tufted backing according to the invention actually has a higher breaking strength and elongation than tufted backings not including the distinguishable layer.

The barrier fabric is of two ply construction, a film of crystalline polypropylene and a fabric substrate secured to the soaker fabric. The laminae construction can resist degradation at laundering temperatures of up to 130.degree. C.

Abstract: A papermaker's fabric is provided having a spun bonded reinforcement. A layer of spun bonded material may be placed in any one of a number of possible locations in the fabric, depending upon the felt stratification desired. For example, it may be attached to the upper surface (or paper contacting side) of the base fabric layer; to the lower surface (or machine contacting side) of the base fabric layer; between two base fabric layers, in the case of a laminated felt; between layers of fibers; or in any other desired location. The spun bonded material may be attached through the use of needling or by use of adhesives, low melts, or ultrasonic methods.

Abstract: A structural reaction injection molded motor vehicle bumper beam comprises a preform formed of layers of interlaced glass fibers and chopped glass fibers wherein most of the interlaced fibers are oriented longitudinally of the bumper beam. A two-component, non-filled reaction injection molding polymeric/pure polyurethane based resin with a neat elongation in excess of about 50% bonds the fiberglass layers together in a composite bumper beam structure wherein the fiberglass provides substantial strength and stiffness and the highly compliant resin allows extensive beam deflection without catastrophic cracking to enable the bumper beam without other assistance to absorb sufficient energy in repeated impacts to meet in-service requirements.

Abstract: This invention pertains to papermaking felts, methods of making such felts, methods of using the felts, and methods of making paper using such felts.
