  • Publication number: 20100255270
    Abstract: The present invention provides a fabric and a fabric structure made of yarns with reduced water absorption. The fabric comprises yarns and interstices between the yarns, the interstices between the yarns having an average width of greater than 100 ?m. At least one of the yarns is comprised of multiple fibers. Said at least one yarn has voids between the fibers wherein the voids are filled up with a polymer material. The interstices remain open and the size of the interstices is the same as before the treatment. The filling of the voids between the fibers with the polymer material prevents the absorption of water into said voids and therefore leads to reduced water absorption of the fabric. The polymer material is substantially only located within the voids of the yarn and has embedded the fibers within the outer surface of said yarn.

    Abstract: Textile materials having radar attenuating properties based upon a polymer enclosed scrim having hollows which are at least partially filled with radar attenuating material. The scrim is sandwiched between two or more polymeric layers, the spaces being the interstices of the scrim. Suitable radar attenuating materials for inclusion in these spaces include carbon granules, carbon fiber, carbonyl iron, ferrites or metal coated microspheres. Carbon fiber is conveniently used in chopped or otherwise relatively short fiber form. The textiles offer lightweight with equivalent radar attenuation performance to known textiles and may include further radar attenuating material in polymeric components to provide enhanced attenuation effect.

  • Patent number: 5683747
    Abstract: Carbon fiber mat are embedded in a coating by first rolling on a coating of e.g. epoxy on the floor or wall, then applying sheets of fine carbon fibers, (optionally) removing the carbon fiber which is not adherent after the coating has dried, then applying one or more additional top coats of coating to additionally embed the carbon fibers. The result is an electrically conductive floor and/or wall coating system useful in antistatic rooms such as clean rooms, operating rooms, etc. Coatings can be sol vent based or waterborne urethanes, epoxies, alkyds, polyethylenes, acrylics, vinyls, vinyl acetates, esters, polyesters, sulfones, polysulfones, silicones, polysilicones and others. The preferred mats are carbon fiber "veils" or "paper" generally having a density of about 0.75 oz./square yard.

  • Patent number: 5637348
    Abstract: The present invention provides a method of increasing the sun protection factor (SPF) rating of a fiber or fabric, comprising the steps of providing a UVR absorber, applying the UVR absorber to a fabric, whereby the UVR absorber is attached to the fiber and an application of less than 3% UVR absorber on weight of fiber produces an SPF rating of greater than 20 for the UVR absorber and fabric combination.
