    Abstract: The invention relates to a process for producing polyurethane prepregs which are stable during storage, and to mouldings (composite components) produced therefrom. The prepregs or components are produced by mixing (meth)acrylate monomers, (meth)acrylate polymers, hydroxy-functionalized (meth)acrylate monomers and/or hydroxy-functionalized (meth)acrylate polymers with uretdione materials and moreover with aromatic amines which accelerate a free-radical polymerization reaction. This mixture or solution is applied by known processes to fibre material, e.g. carbon fibres, glass fibres or polymer fibres, and is polymerized at room temperature or higher temperatures with the aid of initiators, e.g. dibenzoyl peroxide. Instead of amine acceleration and subsequent hardening with initiators, it is also possible to use other known room-temperature curing systems, e.g. permaleate systems. Polymerization, e.g. at room temperature or at up to 80° C.

  • Publication number: 20130227759
    Abstract: A fabric that contains a blend of textile and polyarylene sulfide fibers is provided. At least a portion of the textile fibers, polyarylene sulfide fibers, or a combination thereof are coated with an emulsion copolymer that is crosslinked. The copolymer composition is cured after it is applied to the fibers to initiate the formation of crosslink bonds between the emulsion copolymer and create a three-dimensional network that is capable of coating and encapsulating the fibers. It is believed that this three-dimensional network is able to physically entrap disperse additives when applied to the fibers. Still further, the present inventors have discovered that the emulsion copolymer can uniformly coat the fibers and thus readily receive the additive, which eliminates the need for high temperatures and/or pressures during a dyeing process, for example, and can also result in a relatively uniform coating of the additive on the fibers.

  • Patent number: 7928282
    Abstract: The present invention provides a substrate treated with an linked enzyme. It has been discovered that a substrate treated with a linked enzyme can be effective in improving the ability of the substrate to absorb viscoelastic materials, such as menses, by cleaving a protein structure present in some viscoelastic materials. In addition, the linked enzyme is less likely to migrate from the treated material onto the user, as compare to an enzyme being placed directly on the substrate, thereby reducing the risk of sensitization to the user of the absorbent product. Also provided by the present invention are absorbent articles which contain at least one surface or layer containing the linked enzyme.

  • Patent number: 7855161
    Abstract: The purpose of the present invention is to provide a photocatalytic fiber which excels in durability, and decomposition ability against harmful components and can be mass-produced at low cost, a fabric using the fiber, and a fabric product using the fabric. The photocatalytic fiber of the present invention contains a photocatalyst being attached to the fiber. The fiber is preferably having an aspect of forming a thread to which the photocatalyst being attached by spinning after dipping the fiber in a solution at least containing the photocatalyst, an aspect of forming the thread to which the photocatalyst being attached by dipping the fiber in the solution containing at least the photocatalyst after spinning, and an aspect wherein the photocatalyst is a photocatalytic apatite. The fabric of the present invention is characterized by using the photocatalytic fiber. The fabric product of the present invention is characterized by using the fabric.

  • Patent number: 7838447
    Abstract: A pre-moistened wiper that exhibits good antimicrobial kill at relatively small levels of antimicrobial agent is provided. In one embodiment, for example, the wiper contains a sanitizing formulation that includes between about 0.01% by weight to about 1% by weight of an antimicrobial agent, including a quaternary ammonium compound, and water. The sanitizing formulation is capable of being released from the wiper as a solution such that the quaternary ammonium compound is present within the solution in an amount less than about 2000 parts per million of the solution. The wiper can exhibit a log reduction for E. Coli of at least about 2.

  • Patent number: 7838446
    Abstract: A wood enhancement agent treated engineered wood product. The wood enhancement agent typically includes at least one of a preservative, a water repellant, a fungicide, an insecticide, a stabilizing agent, wax, an ultra-violet light inhibitor, and combinations thereof, and may also include an antioxidant. The wood enhancement agent is incorporated into the engineered wood product during a billet making process or after forming the billet. The wood enhancement agent may be applied simultaneously with a bonding agent or at a later time, for example applied to a scrim log mat during a pre-press process or inside a steam press chamber. Alternatively, the wood enhancement agent may be applied to a warm billet after steam press, or to a reheated billet, by dipping, spraying, or flood coating the billet, or by diffusion, vacuum impregnation, pressure, or a combination thereof.

  • Patent number: 7833915
    Abstract: In order to provide grease, oil and wax resistance to a paper substrate, a coating containing a binder, a filler material and calcium carbonate is used. The coating of the invention is essentially free from fluorocarbons, which are considered harmful to human and animal populations, and surfactants and other chemicals which may alter the color of the coated paper. The coated paper has a GE brightness level between approximately 50 and approximately 90, while providing superior grease, oil and wax resistance.

  • Patent number: 7815995
    Abstract: A textured fabric having at least one surface that contains peaks and valleys is provided. Greater than about 90% of the peaks and less than about 10% of the valleys are disposed with a treatment composition, the treatment composition comprising a latex polymer. In one embodiment, for example, the textured fabric is a hydraulically entangled composite fabric formed from a spunbond nonwoven web and pulp fibers. When coated onto the fabric, the treatment composition may form a thin film layer on the fiber surface that prevents fibers or zones of fibers from breaking away from the surface as lint. Further, because the coating is applied only to the peaks, the valleys may remain free of the latex polymer and substantially maintain the absorbency of the uncoated fabric.
