  • Patent number: 9090999
    Abstract: A fiber is prepared by melt extruding a composition including specific amounts of a polyamide and a polyphenylene ether along with a compatabilizer. Particular combinations produce fibers having a desirable combination of good tenacity and low denier per fiber. Compared to a fiber prepared from polyamide alone, the present fiber exhibits improved heat resistance and flame resistance.

    Abstract: The invention relates to unique applications for the novel high melt flow, low viscosity, selectively hydrogenated styrene-butadiene-styrene (hSBS) or selectively hydrogenated controlled distribution styrene-butadiene/styrene-styrene (hSBSS) block copolymers, wherein the melt flow rate of said block copolymer is at least 100 g/10 min at 230° C. under 2.16 kg mass according to ASTM D1238. These block copolymers are novel and have the highest melt flow rate of any styrenic block copolymer also possessing high strength and elasticity. It has applications that prior to the present invention were not normally possible due to the normal low melt flow rate of styrenic block copolymers. The present invention also encompasses various fields of use such as a fiberglass hSBS or hSBSS reinforced mat, low viscosity hSBS or hSBSS coatings for industrial uses, hot melt adhesives prepared from hSBS or hSBSS blended with polyalpha-olefins, and elastic film, fiber, and nonwoven constructions using hSBS or hSBSS.

    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.

  • Publication number: 20040219846
    Abstract: A composite sheet biasable into a tubular shape to form a sleeve for isolating or protecting elongated items is disclosed. The sheet has a reflective surface formed by a metal foil layer overlying a flexible polymer layer having a metalized surface. A biasable polymer netting layer is positioned overlying the flexible layer opposite the metalized surface. The netting layer is formed of elongated members that define interstices. A damping layer of non-woven material is positioned adjacent to the netting layer. An adhesive layer is positioned between the flexible layer and the netting layer to bond the netting layer and the damping layer to the flexible layer. Biasing is effected by the elongated members of the netting layer which are stiffer in the circumferential direction around the sleeve to provide radial stiffness.

  • Patent number: 6774068
    Abstract: Disclosed is a thermoplastic felt structure for an automobile interior substrate, comprising a pair of mat units, each mat unit having a felt layer which is made by a mixture of a jute fiber and a PP fiber mixed in the weight ratio of about 5 to 5˜6 to 4 and a PP foaming fiber adhered to one side of the felt layer, said mat units being coupled each other on the other sides of the felt layers. With this configuration, a thermoplastic felt structure for an automobile interior substrate can prevent a deflection thereof, and have high strength and stiffness, heat-resistance and impact-resistance. Further, the present thermoplastic felt structure can decrease the cost of raw material, enhance the fuel efficiency with a lightweight body, and accomplish a simple manufacturing process.

  • Patent number: 6753274
    Abstract: Disclosed herein is a stabproof and bulletproof panel. The stabproof and bulletproof panel includes a bulletproof panel 40 and a plurality of stabproof panels 60. The bulletproof panel 40 is comprised of a front plate 45, a plurality of high density polyethylene films 44 stacked with one on top of another for dispersing impact energy, and a rear plate 46 formed by sewing together a plurality of aromatic polyamide woven fabrics for minimizing frictional heat and deformation. The front plate 45 consists of a plurality of aromatic polyamide woven fabrics 41, a felt 50 formed by forcibly inserting thin aromatic polyamide fibers or high density polyethylene fibers 52 and a shock-absorbing member 51 into a scrim woven in the form of a net using aromatic polyamide fibers or high density polyethylene yarn, and a plurality of aromatic polyamide woven fabrics 43. The stabproof panels 60 are brought into tight contact with the front surface of the bulletproof panel 40.

  • Patent number: 6514889
    Abstract: A non-woven synthetic sheet material for use in sound insulation and/or thermal insulation is described. The sheet material is a felt or mat of substantially uniform synthetic fiber thickness and defines opposed flat surfaces. The sheet material is needle-punched from at least one of the opposed flat surfaces thereof to cause the synthetic fibers to intertwine to form a pliable sound and/or thermal insulating sheet. The insulating sheet has a density in the range of from about 100 to 1500 g/m2 and a homogeneous integrity resistant to fragmentation. Preferably a polymeric film is interconnected to a surface of the synthetic fiber sheet by a further needle punch step the polymeric film is preferably a metalized polyethylene film. The material has a multitude of uses in the construction industry. The felt may also be provided in strip form for use in the framing of wooden structures to sound insulate interconnected parts.
