  • Patent number: 6809048
    Abstract: The present invention provides a process for producing a three dimensionally texturized liquid resistant laminate having a fibrous nonwoven layer and a liquid resistant layer. The process has the steps of placing the fibrous layer and the liquid resistant layer in juxtaposition to form a laminate, attaching the fibrous layer and the liquid resistant layer at a plurality of spaced-apart bond locations, heating the bonded laminate to a temperature that activates the latent shrinkability of the liquid resistant layer, and allowing the heated laminate to retract such that the liquid resistant layer shrinks and said fibrous layer forms gathers between said bond locations, thereby forming a three dimensional texture and heat annealing the laminate. The invention additionally provides a three dimensionally texturized laminate having a fibrous layer and a nonelastic liquid resistant layer.

  • Patent number: 6770687
    Abstract: A water-based security printing ink is provided with two means of security. The use of a variable light absorbing and/or transmitting pigment or dye is a first security and a water repelling agent is provided as a second security. Visible images can be generated from the printed ink upon exposure to UV or infrared light. The water repelling agent renders the image waterproof and differentiates the printed image from the substrate, which allows the image to be detected upon exposure to water or other aqueous mixture. Suitable inks can be used in conventional printing methods, such as jet printing, lithography, offset printing and impact printing. Also provided are substrates imaged with these security printing inks.

  • Patent number: 6764969
    Abstract: A textile substrate is provided which is coated with a film comprising iron (III) oxide hydroxide and aluminum oxide hydroxide. This film or coating is formed by contacting the textile substrate with an aqueous solution comprising ferrous or ferric salts and aluminum salts. The iron (II), iron (III), and aluminum ions are hydrolyzed and the iron (II) ions are also oxidized under controlled conditions. These hydrolyzed species then, it is believed, coprecipitate or copolymerized to on the textile surface to form a smooth, coherent, substantially amorphous iron (III) oxide/aluminum oxide hydroxide film or coating on the surface of the substrate without forming an insoluble iron (III) or aluminum hydroxide precipitate in the solution. This is accomplished by controlling the reaction conditions such that the rates of adsorption onto the substrate surface of both iron (III) and aluminum oxide hydroxides are greater than the rates of formation of said same oxide hydroxide particles.

  • Patent number: 6759353
    Abstract: An absorbing article has a hydrophobic, liquid impermeable back side layer and a liquid permeable top layer together with an interposed hydrophilic core layer. The article is made so that at least the back side layer comprises hydrophobic vegetable fibers, preferably kapok fibers, and that the top lay can comprise wool fibers. Such an article is advantageous since it may be used for keeping the user warm in situations where there is need for liquid absorption without the risk of unintended temperature elevation known from plastic products.

  • Patent number: 6759352
    Abstract: A composite carbon fiber material is formed of one or more layers of carbon fiber material in which the carbon fibers are aligned all in the same direction and a mat of nonwoven, woven, or off-axis unidirectional carbon fibers are laminated together. Layers may be used individually or as a hybrid. The layers can be preimpregnated or impregnated during processing using thermoplastic or thermosetting resins. A layer of thermoplastic resin is applied either over the surface or within the composite structure, and the resin permeates the material so as to provide a more stable mechanical structure once the resin is processed. The material combines good mechanical strength with improved electrical current carrying properties when compared with the aligned carbon fiber layer alone. The layering sequence, layer type, and resin type can be specified to tailor electrical properties, mechanical properties, durability, and wear resistance.

  • Patent number: 6720277
    Abstract: A protective fabric of high penetration resistance is formed from a plurality of layered, densely woven base fabrics, each formed by tightly weaving multifilament yarns to obtain a warp yarn “density” or “cover” in excess of 100% at the center of the fill yarn, and a fill yarn density or cover preferably also in excess of 75%. The yarns themselves preferably comprise a high modulus, high breaking strength yarn of materials such as Kevlar, Spectra, or Vectran. The resultant layered fabric offers especially high penetration resistance to weapons such as ice picks and the like. Additional resistance to penetration by sharp knives is provided by interruptedly coating the base fabric with an epoxy in such a manner as to inhibit penetration while providing drapability and breathability.

  • Patent number: 6709992
    Abstract: Process for preparing durable, re-usable intermediate toner image-transfer belts or electrostatic transfuse belts. The present belts have a continuous elastomer-impregnated fibrous fabric support and at least one outer smooth release layer of a cured elastomer polymer. The invention is characterized by the application of a thin primer layer of a hydrolyzable polyfunctional silicone composition between the elastomer-coated surface of the fabric support and the outer elastomer polymer layer. The polyfunctional silicone chemically-bonds to the elastomer of the fabric support during hydrolysis and chemically-bonds to the outer elastomer layer during its cure, to form a durable, heat-resistant transfuse belt. The layers maybe applied to the fabric support by spray application as dilute solutions.
