Definitions

  • Synthetic fiber ropes have been used in a variety of applications, including various marine applications.
  • One type of rope that has excellent properties is rope made from high modulus polyolefin fibers and/or yarns.
  • High tenacity polyolefin fibers are also known as extended chain or high molecular weight fibers. These fibers and yarns are available, for example, as SPECTRA® extended chain polyethylene fibers and yarns from Honeywell International Inc.
  • Synthetic ropes continue to replace steel wire in many marine applications. As synthetic ropes progress to replace steel wire in many cyclic bend-over sheave (CBOS) applications, the need exists to improve the fatigue life of high performance synthetic ropes. In particular, the need exists to improve the performance of ropes made from high performance polyolefin fibers and yarns.
  • CBOS cyclic bend-over sheave
  • a rope having improved CBOS fatigue resistance comprising a blend of high tenacity polyolefin fibers with other high tenacity fibers that are not polyolefin fibers, the rope and/or the fibers being coated with a composition comprising an amino functional silicone resin and a neutralized low molecular weight polyethylene.
  • a method of improving the CBOS fatigue life of a rope comprising forming the rope from high tenacity fibers, and coating the rope and/or the fibers forming such rope with a composition comprising an amino functional silicone resin and a neutralized low molecular weight polyethylene.
  • ropes comprising high modulus polyolefin fibers, such as extended chain polyethylene fibers, and yarns made therefrom have been suggested for use in marine applications.
  • One such use of the ropes is for heavy lifting and mooring of objects onto the seabed.
  • Other applications include offshore oil and gas exploration, oceanographic, seismic and other industrial applications.
  • the most preferred applications for ropes of this invention include deep sea lifting and placement.
  • the fibers utilized in the rope construction preferably comprise extended chain (also known as high molecular weight, high tenacity or high modulus) polyolefin fibers, particularly high modulus polyethylene fibers and polypropylene fibers.
  • extended chain also known as high molecular weight, high tenacity or high modulus
  • polyolefin fibers particularly high modulus polyethylene fibers and polypropylene fibers.
  • the polyethylene employed is a polyethylene having fewer than about one methyl group per thousand carbon atoms, more preferably fewer than about 0.5 methyl groups per thousand carbon atoms, and less than about 1 wt. % of other constituents.
  • aramid fibers suitable fibers formed from aromatic polyamides are described in U.S. Pat. No. 3,671,542 , which is incorporated herein by reference to the extent not inconsistent herewith.
  • Preferred aramid fibers will have a tenacity of at least about 20 g/d, an initial tensile modulus of at least about 400 g/d and an energy-to-break at least about 8 J/g, and particularly preferred aramid fibers will have a tenacity of at least about 20 g/d and an energy-to-break of at least about 20 J/g.
  • aramid fibers will have a tenacity of at least about 23 g/d, a modulus of at least about 500 g/d and an energy-to-break of at least about 30 J/g.
  • poly(p-phenylene terephthalamide) filaments which have moderately high moduli and tenacity values are particularly useful in forming ballistic resistant composites. Examples are Twaron® T2000 from Teijin which has a denier of 1000. Other examples are Kevlar® 29 which has 500 g/d and 22 g/d as values of initial tensile modulus and tenacity, respectively, as well as Kevlar® 129 and KM2 which are available in 400, 640 and 840 deniers from du Pont.
  • Suitable liquid crystal copolyester fibers for the practice of this invention are disclosed, for example, in U.S. Pat. Nos. 3,975,487 ; 4,118,372 and 4,161,470 .
  • Liquid crystal copolyester fibers are available under the designation Vectran® fibers from Kuraray America Inc.
  • Suitable polybenzazole fibers for the practice of this invention are disclosed, for example, in U.S. Pat. Nos. 5,286,833 , 5,296,185 , 5,356,584 , 5,534,205 and 6,040,050 .
  • Polybenzazole fibers are available under the designation Zylon® fibers from Toyobo Co.
  • Rigid rod fibers are disclosed, for example, in U.S. Pat. Nos. 5,674,969 , 5,939,553 , 5,945,537 and 6,040,478 . Such fibers are available under the designation M5® fibers from Magellan Systems International.
  • one type of high tenacity fibers is a polyolefin fiber, more preferably a polyethylene fiber.
  • the percent of high tenacity polyethylene fibers in the ropes may vary widely, depending upon the other type of high tenacity fibers employed and the desired properties of the fibers.
  • the high tenacity polyethylene fibers may comprise from about 20 to about 80 weight percent, more preferably from about 30 to about 70 weight percent, and most preferably from about 40 to about 60 weight percent, based on the total weight of the high tenacity fibers in the rope.
  • ropes may be formed from about 80 to about 20 weight percent high tenacity polyethylene fibers and correspondingly from about 20 to about 80 weight percent of liquid crystal copolyester fibers; more preferably from about 70 to about 30 weight percent of the high tenacity polyethylene fibers and correspondingly from about 30 to about 70 weight percent of liquid crystal copolyester fibers; most preferably from about 40 to about 60 weight percent high tenacity polyethylene fibers and correspondingly from about 60 to about 40 weight percent of liquid crystal copolyester fibers.
  • the rope comprises from about 70 to 55 weight percent liquid crystal copolyester fibers and correspondingly from about 30 to about 45 weight percent high tenacity polyethylene fibers, based on the total weight of the high tenacity fibers in the rope.
  • all or substantially all of the fibers in the rope are formed from liquid crystal copolyester fibers.
  • the different types of fibers useful in the ropes of this invention may be blended in any suitable manner. For example, strands of one type of fibers may be twisted with strands of another type of fibers to form a combined strand that is then braided into a rope. Alternatively, the fibers can be combined as a bicomponent fiber, having a sheath and a core. Other constructions may also be employed. The different types of fibers may be present at any desired location in the rope.
  • the ropes of this invention preferably comprise blends of two or more high tenacity fibers, or consist essentially of blends of two or more high tenacity fibers, optionally together with the fluoropolymer fibers.
  • These ropes may be of any suitable construction, such as braided ropes, twisted ropes, wire-lay ropes, parallel core ropes, and the like. Most preferably, the rope is a braided rope.
  • the ropes may be of any suitable diameter and may be formed in any suitable manner from the desired fibers and/or yarns. For example, in forming a braided rope a conventional braiding machine may be employed which has a plurality of yarn bobbins.
  • Yarns from one type of high tenacity fibers may be formed into a subrope which is then formed into a rope (such as by braiding) with a subrope formed of yarns from the other type of high tenacity fibers.
  • a subrope may be formed from blends of the high tenacity fibers and such subrope may be formed into a rope using other such subropes or different types of subropes, by braiding or any other desired technique.
  • the high tenacity yarns that form the rope may be of any suitable denier, and the yarns of the fluoropolymer fiber may be of the same or different denier than the yarns of the high tenacity fibers.
  • the high tenacity yarns may have a denier of from about 50 to about 5000, more preferably from about 75 to about 2000 denier, still more preferably from about 200 to about 2000, and most preferably from about 650 to about 1500 denier.
  • the fluoropolymer yarns may have a denier of from about 50 to about 2500, and more preferably from about 400 to about 1600.
  • the neutralized low molecular weight polyethylene is present in an amount of from about 30 to about 90 percent by weight, with the amino functional silicone resin correspondingly being present in an amount of from about 10 to about 70 percent by weight. More preferably, the neutralized low molecular weight polyethylene is the major component of the coating, such as from about 55 to about 85 percent by weight of coating composition, with the amino functional silicone resin being present in an amount of from about 15 to about 45 percent by weight.
  • the composition may contain a variety of other additives, depending on the desired end properties.
  • the neutralized low molecular weight polyethylene is in the form of an emulsion.
  • the polyethylene is fully neutralized.
  • the low molecular weight polyethylenes are also known as polyethylene waxes and are sometimes called wax dispersions.
  • these polyethylene waxes, also called resins generally have a molecular weight of less than about 6000 Dalton, more preferably less than about 5000 Dalton, even more preferably below about 3500 Dalton, and most preferably between about 300 and about 3000 Dalton.
  • the overfinish composition was prepared from an amino functional silicone resin and a neutralized low molecular weight polyethylene.
  • the amino functional silicone resin was an emulsion having a silicone content of 35 weight percent, a pH of 4.5-6.5 and included a non-ionic emulsifier, available from Dow Corning (2-8818 emulsion).
  • the neutralized low molecular weight polyethylene was a neutralized non-ionic polyethylene wax emulsion (F Kunststoffone® 1566 from Apollo Chemical), having a solids content between 29% and 31%, and pH in the range of between 9.0 and 11.
  • Example 1 is repeated, except that the rope is formed from 40% by weight of high tenacity polyethylene fibers and 60% by weight of liquid crystal copolyester fibers, and has a diameter of about 40 mm. Similar results are noted.
