  • Patent number: 6936327
    Abstract: Disclosed herein is a composite comprising at least one heat shrinkable adhesive layer stitch-bonded with yarns, which shrink less than the adhesive layer or do not shrink, when the adhesive layer is exposed to heat. The stitch-bonded yarns form loops upstanding from the shrunk adhesive layer and the loops create a textured surface on the composite, and the composite is substantially inelastic after the adhesive layer is shrunk. The composite may further comprise at least one fibrous layer stitch-bonded to the shrinkable adhesive layer, and the fibrous layer is less shrinkable than the adhesive layer or is substantially non-shrinkable.

  • Patent number: 6846545
    Abstract: A material to reduce the effects of trauma received from the impact of a projectile. One embodiment is a needle-punched, non-woven material including at least one type of ballistic fibers selected and oriented to provide a cushioning effect and maintain a high compressive restitution constant. A percentage of the fibers are oriented with at least their ends lying approximately perpendicular to the fabric plane and/or oriented to lie in a waveform generally along or parallel to the fabric plane. This enables the ends of the fibers lying perpendicular to the fabric plane to cushion the impact from the projectile by dissipating energy through compressional resistance, and the fibers along the fabric plane to reduce energy through dispersal along fiber lines, thereby reducing the trauma resulting from an impact.

    Abstract: A non-woven flame blocking fabric and method utilizes a fibrous blend of a concentration of cellulosic organic fibers (A) and a concentration of inorganic fibers (B) to which a flame retardant composition (C) is applied. The concentrations of fibers are blended and treated to form a flame retardant fiber blend capable of forming a non-woven flame blocking fabric that upon exposure to flame forms a reinforced char barrier (D) that prevents the flame from igniting any flammable substrate. The reinforced char barrier (D) includes the carbonized cellulosic organic fibers and melted inorganic fibers. A concentration of binder fibers or powders (E) may alternatively supplement the fiber blend to produce a low profile flame blocker fabric upon activation and calendaring.

  • Patent number: 6787493
    Abstract: A formable biodegradable filament nonwoven fabric and a production method therefor are provided. A biodegradable polymer comprising a thermoplastic aliphatic polyester as its principal component is melted and extruded through a spinneret into filaments. While being quenched with quench air blow, the extruded filaments are drafted at a drafting speed of 1,000 to 2,500 m/min by means of a suction device disposed below the spinneret. The drafted filaments are spread and accumulated on a movable collector surface thereby to be formed into a web, which is then treated for formation of a nonwoven fabric. The constituent filaments of the nonwoven fabric has a polymer supercool index of 0.3 to 0.6.

  • Patent number: 6784127
    Abstract: A polyurethane elastomer fiber non-woven fabric contains polyurethane elastomer fiber filaments melt-bonded with one another, and has a tensile elongation of 100% or more, a 50% elongation recovery of 75% or more and a tear strength per METSUKE of 5.5 gf or more. The non-woven fabric can be prepared by a method of providing a thermoplastic polyurethane elastomer having Shore hardness A of 92 or more, drying the elastomer to a water content of 150 ppm or less, and melt-spinning and, at the same time, spraying it together with a high speed gas stream so as to deposit and laminate the elastomer into a sheet form. A synthetic leather using the non-woven fabric is also provided. The non-woven fabric has not only an excellent elasticity but also high tear strength.
