  • Patent number: 11204477
    Abstract: A method for stranding aramid yarn around an endless core includes a stranding step that involves a stranding apparatus having at least one yarn bobbin. The bobbin revolves around its own axis and the bobbin revolves around the core, wherein the yarn unwinds from the bobbin and winds around the core. The yarn is a continuous aramid yarn provided with 0.05 to 0.95 wt %, based on the weight of the aramid, of a finish including an organophosphorus compound. The organophosphorus compound is a compound of the formula X1X2X3P?O. X1, X2, and X3 are independently selected from Y1-, Y1-O—, and M-O. Y1 is a branched or straight-chain C1-C20 alkyl, aryl or alkenyl. M is selected from Li, Na, K, or ammonium. At least one of X1, X2, or X3 is selected from Y1- or Y1-O—.

  • Patent number: 10450696
    Abstract: Linear tension member having multiple fibers and at least 0.1 wt % of solid hydrophobic organic nanoparticles with a mean diameter of 10-300 nm and a standard deviation ? of at least 10% of the mean value, which linear tension member has a linear mass density of at least 10.000 dtex and has at least 80 wt % of fibers having a mass density higher than 1 g/cm3. The disclosure also pertains to the use of such particles for making a linear tension member buoyant and to a process to manufacture a floating linear tension member.
