  • Patent number: 6349754
    Abstract: An interior automotive skin material has a thermoplastic resinous base coat/clear coat paint film bonded to the outer surface of a thermoplastically formable semi-rigid resinous backing sheet. The base coat/clear coat paint film is preferably formed by dry paint transfer techniques in which the clear coat layer and pigmented base coat layer are coated on a polyester carrier and dried, followed by transfer-laminating the base coat/clear coat paint film from the carrier to the backing sheet on which the clear coat layer forms a low gloss protective outer surface. The clear coat material preferably comprises an alloy of an acrylic resin and a fluoropolymer resin, preferably polyvinylidene fluoride. The low surface gloss of the outer clear coat is produced by a dispersed fine particulate filler such as silica combined with coating the outer clear coat layer on a matte carrier.

  • Patent number: 6346315
    Abstract: House wares, including frangible wares, comprising glassware, earthenware including china, and ceramics, the glassware including dishes and vessels such as drinking glasses, are coated with a protective plastic coating, usually including an initial adhesion-promoting silane, and a coating of urethane, such as a high temperature urethane to give protection to the underlying layers, and to the article, including protection within a commercial dishwasher. The silane combines with glass, and couples strongly with urethane. The urethane is highly receptive to decoration, which may be transferred or printed onto the urethane surface. If sublimation is applied to the decoration, then subsequent application of a sealing outer coat of urethane may prove unnecessary.

  • Patent number: 6335092
    Abstract: A composite staple fiber, wherein a polymer component A and a polymer component B are alternately arranged in a fiber horizontal cross-section; the fiber periphery is entirely covered with the polymer component A; both the polymer component A and the polymer component A have a substantially flat shape; the lengthwise ends of the polymer component B are located 0.05 to 1.5 &mgr;m from the fiber surface; and the weight ratio of the polymer component A to the polymer component B is from 90/10 to 10/90. The composite staple fiber of the present invention is not peeled or split by a carding and a needle punching treatments, but is divided and split in the subsequent water jet entanglement, resulting in flat ultrafine fibers having a sharp-edged structure.

  • Patent number: 6333093
    Abstract: Multilayer anti-microbial materials formed to produce an interference colour, and thus an indictor of anti-microbial effect, are provided. The materials include a partly reflective base layer and a partly reflective, partly transmissive top layer balanced to produce an interference colour. The top layer is formed from an anti-microbial metal with atomic disorder. Dissolution or a change in composition of the top layer on contacting an alcohol or electrolyte causes a change in optical path length so as to produce a change in the interference colour of the material. Multilayer, laminated wound dressings are also provided. The dressing includes a first and second layer, and preferably a third layer. The first and third layers are formed of perforated, non-adherent materials and most preferably carry an anti-microbial coating as above. The second layer is sandwiched between the first and third layers and is formed of an absorbent material. At least one of the layers is formed from a plastic material.

  • Patent number: 6322893
    Abstract: A process is disclosed for the manufacture of reinforced composites. This method provides a process that allows for the direct mixing of discontinuous reinforcement such as wet chopped strands of glass fiber or continuous reinforcement such as glass strands, with an aqueous suspension of a solution polymerized polymer, such as polyvinyl chloride. The process results in a cost-effective means for reinforcing polymers such as PVC while simultaneously substantially improving properties such as impact strength, stiffness, and moldability without the need for a binder.

  • Patent number: 6319438
    Abstract: An automotive trim product is made as follows. A single or multiple layer sheet is extruded so as to include at least one color pigmented and/or metallized layer therein. The sheet is then thermoformed into a three-dimensionally shaped preform via vacuum forming or the like. The preform is placed into a cavity of an injection molding apparatus and heated semi-molten material is injected thereinto. The semi-molten material bonds to the preform in the cavity. After cycling, the molding apparatus ejects a final automotive trim part. Optionally, some processing (e.g. trimming) may be performed following ejection.
