Definitions

  • the present invention relates to a rope with high cross-sectional symmetry having high stiffness and breaking strength.
  • ropes and cables exist for different operations.
  • ropes are desired, that are twisted and braided with high breaking strength and simultaneously with low mass density.
  • fibres such as Aramids, Liquid Crystal Polymers, PBO and Ultra High Molecular Weight Polyethylene
  • ropes with high breaking strength have been produced, with a breaking strength that is greater than for steel wire of the same diameter.
  • the weight of such ropes is only one-sixth of the weight of a same size steel wire.
  • One of the advantages of such ropes is that they are much easier to handle than steel wire.
  • Applications for such ropes are e.g. in fishing with nets and trawls, where the ropes are used for back strop attachments, bridles and sweep lines.
  • a common type of ropes used for trawl warps, bridles and sweep lines are twisted steel wire ropes.
  • twisted steel wire rope the most common construction is based on seven strands where one is in the centre and the remaining six are twisted around the centre strand. The centre strand is therefore acting as a core filling up the void.
  • steel wire ropes the core is often made from other materials like a bundle of fibres, twine or even synthetic ropes. As the steel wire is very stiff and harder than such softer materials, the core will be clenched and fill eventual voids. The result is that these soft core steel ropes have high strength, excellent abrasion resistance, circular cross-section and the stiffness is high in axial as well as in radial directions.
  • US-A-4378725 discloses a method for producing a sealed rope of braided or twisted filaments.
  • Heat-shrinkable filaments are braided or twisted about a core of a thermoplastic material to form a rope and the rope is placed under tension and treated to cause the thermoplastic core material to melt.
  • the rope is maintained at a temperature sufficient to cause the heat-shrinkable filaments to shrink but not to melt, whereby the shrinking of the filaments, while the rope is under tension, reduces the cross section of the rope and causes the material to penetrate into the openings between and to surround and seal the filaments of the rope.
  • DE-B-10 73 677 relates to a curtain cord and a construction thereof.
  • EP-A-1033435 relates to a composite cord for reinforcement of elastomers comprising a core of a high polymer material, a first layer of steel filaments twisted around said core and a second layer of steel filaments twisted around said first layer.
  • the polymer material is present in a sufficient volume to create gaps between adjacent filaments of the first layer and possibly also between the filaments of the second layer.
  • the composite cord is characterised by a decreased fretting of the steel filaments.
  • US-A-3 686 855 relates to a cable with a solid core made of a relatively incompressible thermoplastic material.
  • WO-A-00/50687 relates to a low stretch elevator rope in which a plastic core has a central strength member that does not increase the weight of the rope by more than 5 %. Moreover, the plastic core has a diameter exceeding 50 % of the diameter of the rope, when measured prior to winding steel strands onto the core.
  • the steel strands that are wound around the core are conventional and are so wound that the plastic material of the core essentially fills the inner interstices between the steel strands.
  • the object of the present invention is to provide a strong rope by implementing a stiff core in a rope jacket in such a way that the core will preserve its stiffness and fill out the inside vacancies within the rope permanently.
  • Braiding a fibre rope around a core which is made of thermoplastic material can accomplish this.
  • the thermoplastic core goes through a transition from a first solid phase to a second phase (typically a liquid or semi-liquid phase) and back to the solid phase by means of heating.
  • the core material will adapt to the void space within the rope jacket in which it is enclosed.
  • the rope is then cooled down under tension until the core has regained its solid phase.
  • a sheet layer e.g. overbraid, which has a higher softening point than the core material.
  • ropes of the present invention have sufficient strength for use as towing wires for towing fish trawls, where conventionally much heavier steel wires have been used, which are sensitive to corrosion.
  • the present invention relates to a rope having high stiffness and breaking strength, comprising a core, and at least one jacket enclosing the core, wherein the high breaking strength is obtained by changing the phase condition of the core and optionally said at least one jacket from a first phase condition to a second phase condition while stretching the rope, thereby obtaining a relative movement of said at least one jacket layer and the core, so that the vacancies between the core and jacket are eliminated.
  • a rope with stiffness and high breaking strength is thus obtained.
  • the core comprises a core material and a sheet layer, e.g. braided cover, enclosing said core material. Thereby it is prevented that the core material diffuses, in the second phase condition, towards the surface of the at least one sheet layer/jacket.
  • the core material may be selected from any of a number of suitable thermoplastic materials (i.e., materials that become reversibly softer when heated and retain original properties (hardness) when cooled down).
  • the core is made of a plastic material, such as typically a thermoplastic polymer, a suitable polymer can be selected e.g. from nylon, olefin, or high-density polyethylene (HDPE), chlorinated polyethylene (CPE), polyester, or a combination thereof.
  • the core comprises additionally a central inner core (or "strength member") with different material properties than the main core material, for added strength and/or stiffness.
  • the central inner core is preferably made from a fibre thread or filament, twinned or braided, from a suitable polymer, a single thread or metal wire, e.g. a lead or steel wire.
  • the first phase condition is a solid phase condition for both the core and the jacket.
  • the rope is treated such that the phase of the core changes while the phase conditions of the jacket remain unchanged.
  • the second phase condition for the core is preferably a liquid phase condition but may also be an intermediate phase (semi-liquid phase) or a mixture of a liquid and solid phase, e.g. such that substantially all of the core is in a liquid or semi-liquid phase, though some parts/filaments may remain solid or semi-solid.
  • the phase condition of the jacket is altered but generally however, the jacket remains substantially solid during the processing. (In these embodiments, a portion of the jacket, e.g. filaments or threads with a lower softening point than the main strands of the jacket, go through a phase transition and diffuse further in between the main strands of the jacket.)
  • the at least one jacket layer is preferably made of a plurality of strands where each strand typically is a bundle of fibre filaments, threads or yarns; the jacket is braided in such a way that the strands form at least a three-strand laid rope, such as a four- or six-strand laid rope.
  • the strands may form a strand braided rope, with, e.g. 6, 8, 10, 12, 14, 16, 18, 20, 24, 28 or 32 strands braided.
  • more than a jacket is used, i.e. a sheet layer with a plurality of strands (e.g. 3, 4, or 6) and one or more outer jackets of strands, each outer jacket comprising a plurality of strands, such as described above.
  • the jacket may be made of one or more suitable materials, typically from one or more polymer fibre material such as but not limited to nylon, polyethylene, including high-density and ultra high-molecular weight polyethylene (e.g. DyneemaTM (DSM, Herleen, Netherlands)), aramids, liquid crystal polymers, PBO (polybenzoxazole polymer) or polyester, and any combination thereof, such combinations may also comprise steel wires or in a certain embodiment the jacket additionally comprises thermoplastic fibre threads, that during heating will soften or melt to blend in with the bulk material of the jacket.
  • polymer fibre material such as but not limited to nylon, polyethylene, including high-density and ultra high-molecular weight polyethylene (e.g. DyneemaTM (DSM, Herleen, Netherlands)), aramids, liquid crystal polymers, PBO (polybenzoxazole polymer) or polyester, and any combination thereof, such combinations may also comprise steel wires or in a certain embodiment the jacket additionally comprises thermoplastic fibre thread
  • the jacket is in certain embodiments enclosed by a cover which may be braided, coextruded or pulltruded and is preferably from a material selected from any of the materials listed above or a combination thereof (such as, e.g., from nylon, olefin, polypropylene, thermoplastic filaments, polyester, aramids, liquid crystal Polymers, PBO and polyethylene, including Ultra High Molecular Weight Polyethylene, (e.g. DyneemaTM), and any combination thereof).
  • a cover which may be braided, coextruded or pulltruded and is preferably from a material selected from any of the materials listed above or a combination thereof (such as, e.g., from nylon, olefin, polypropylene, thermoplastic filaments, polyester, aramids, liquid crystal Polymers, PBO and polyethylene, including Ultra High Molecular Weight Polyethylene, (e.g. DyneemaTM), and any combination thereof).
  • the threads and the strands in the at least one jacket are preferably internally fixed together.
  • the force is thereby divided between all the strands and their threads, which co-operate.
  • the at least one sheet layer is elongated such that the fibres in said at least one sheet layer have equal length.
  • the strength is therefore not imposed on one or several fibres but on all the fibres.
  • Such internal fixing may be obtained by contacting (impregnating) the jacket (optionally with the core mounted inside) with an adhesion material, such as preferably polyurethane or another material with similar suitable properties, e.g. by immersion, or by other suitable techniques such as spraying or using wet rollers.
  • the changing of the phase condition is by heating the core and optionally said at least one jacket.
  • the temperature for the phase change is in the range of 50-180°C, and preferably in the range of 100-130°C, or in the range of 110-120°C, such as, e.g., about 110, 112, or 115°C.
  • the exact temperature or temperature range will, however, depend on the material or combination of materials comprised in the core, and their properties and softening point(s).
  • the relative movement of said at least one jacket and the core is effected through elongating lengthwise said at least one jacket layer, and optionally also the core.
  • the elongation results in that the at least one jacket layer is clenched widthwise (cross-sectional), such that the core material when softened fills up in vacancies between the core and said at least one jacket layer.
  • the cross- sectional symmetry of the rope may after the clenching be circular. However, other cross section symmetries are also possible.
  • the present invention provides a method for producing a rope with high stiffness and breaking strength, such as described above, the method comprising the steps of:
  • the at least one jacket layer and optionally the core are brought in contact with an adhesion material as described above, so that the fibres in the sheet layer are internally joined together prior to the changing of the phase condition of the core.
  • Polyurethane which optionally can be diluted in aqueous solution, is preferred as an adhesion material.
  • the method further comprises removing the excess of said adhesion material and/or optionally moisture from said at least one jacket layer and the core prior to the stretching step.
  • the core 1 is extruded with or without a strength member 2 in the middle.
  • the material used is thermoplastic material of any kind but preferably a polymer.
  • the core is cooled down until it reaches solid state.
  • a sheet layer 3 is applied with a co-extrusion, pulltrusion, wrapping, twisting or overbraiding or a multiple or combination of the methods.
  • the function of the sheet layer 3 is to prevent uncontrolled flow of the liquid or semi-liquid core during processing. In some cases not according to the invention, it is desirable to have the core flowing out to the surface of the rope jacket and in such embodiments sheet layer 3 is not present in the construction.
  • the core 2 with or without sheet layer 3 is fed into the jacket 4 centre during braiding of the strands 5. The rope is now ready for impregnation.
  • the impregnation materials can be solvents of polymers, polyurethane, bitumen or latex or a blend of those materials.
  • a cover 6 can be added at this stage or after the processing. If the core 1 is used without a sheet layer 3 it is advantageous to add such cover 6 prior to the processing but the cover material has to be able to withstand the temperature used in the process.
  • the rope with core is now tensioned and heated up, by means of suitable medium, liquid or air, to the appropriate temperature and simultaneously stretched until it elongates permanently.
  • the core 1 shifts from the solid phase to a liquid or semi-liquid phase.
  • the force applied to the axial direction of the rope will partly be transferred into forces working perpendicular to the rope. These perpendicular forces will move the now liquid core material into the inside voids of the rope and fill them up, to the extent that the sheet layer 3 allows the penetration of the core material.
  • the sheet layer 3 is absent, the core 1 material when in the second phase condition, (typically liquid or semi-liquid phase), will penetrate in-between the strands of the jacket and eventually to the surface of the jacket.
  • the cover sheet 6 has been applied prior to the process it will stop the fluid core material from entering the surface of the jacket 4.
  • the rope construction is now cooled down and the tension is simultaneously lowered.
  • the rope has now undergone permanent change involving shifting phase of the core and both axial and radial stiffness has been achieved by rearranging the rope sub-elements.
