  • Publication number: 20050186875
    Abstract: The present invention is directed to a fabric that is particularly well suited for use as the outer shell fabric of the firefighter's garment. The preferred fabric is 40% Melamine formaldehyde (Basofil) and 60% Para-Aramid (Kevlar) woven of spun yarns and core-spun DREF yarns. The core spun yarn includes one or more filament cores selected from a polymer group consisting of PBO, Aramid, Liquid Crystal Polymer (LCP), Carbon and P-84, with or without a fine metallic wire co-core, and a staple sheath blend consisting of one or more fibers selected from a group consisting of Meta-Aramid, Para-Aramid, Copolymide, PBI, PBO, P-84, Carbon, Kynol, PFR Rayon and/or Modacrylic fibers.

  • Patent number: 6562741
    Abstract: A firefighter garment including melamine high-heat and flame resistant fibers that have been stock dyed to obtain a desired shade or color. The stock dyed fiber is preferably blended with another fiber and the blend spun, by ring or core spinning, into a yarn for use in a protective fabric. Fabric produced by employing a blend of stock dyed melamine fibers and other high temperature fibers offers numerous cost and performance advantages. The elimination of the damage associated with the piece dyeing process allows the fabric to increase its strength and tear characteristics without affecting its thermal performance.
