  • 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.

  • Patent number: 5972434
    Abstract: Fire resistant glass fiber products are produced by coating the glass fibers with at least one nitrogen containing compound and at least 10 weight percent of at least one boron containing compound, drying the glass fibers and curing a binder that is in the coating. The nitrogen containing compound(s) are present in sufficient amounts that there is at least one mol or atom of nitrogen present for each mol or atom of boron present in the boron containing compound(s). When the product is exposed to a fire or high temperatures, such as about 1000 degrees F. or higher, the nitrogen released from the nitrogen containing compound(s) reacts with boron or boron oxide to form a sheath of refractory material around the fibers that protects the fibers and allows the fibers to maintain integrity to higher temperatures and/or for longer times than untreated fibers.
