Definitions

  • the invention is directed to a rope and a method of producing the rope.
  • the invention is directed to a sealed rope and the use thereof in fishing.
  • Ropes used in fishing are susceptible to penetration of sand and/or other small particles that enter the voids in between the yarns or filaments of which the ropes are made of. Upon penetration of the particles, the rope's weight may increase and the rope may be damaged internally by abrasion. Penetration of sand particles into ropes may in particular be the case with trawling or fly-shoot fishing where nets made of the ropes frequently touch the bottom of the ocean, sea or lake. In these fields, penetration of sand in the rope is especially considered problematic because it also results in a decrease of the mesh size of the fishing nets.
  • fishing nets are e.g. funnel- or trouser- shaped, wherein the narrow end of the funnel or trouser is closed by a cod-end (see figure 1 for a funnel-shaped net).
  • the cod-end comprises small braided ropes that are connected by knots to form a square mesh of a particular size.
  • the cod-end should allow small fish to escape the fishing net.
  • the rope's diameter increases and consequently its length decreases by decreasing the length of the rope, the mesh size also decreases.
  • Mesh size of fishing nets are determined by measuring the longest length between two knots when the mesh of the net is stretched (see figure 2).
  • Known methods to determine mesh size are e.g. described in "Mesh Shrinkage in Fishing nets", E. S. Strange, Marine laboratory, Aberdeen (1984), which is incorporated herein in its entirety.
  • US4378725 which is incorporated herein in its entirety, addresses this problem and describes a method wherein a sealed rope is produced by melting a thermoplastic core that is surrounded by heat- shrinkable filaments under tension.
  • the thermoplastic core is dispersed into the voids of the heat- shrinkable filaments and forms a internal sealed layer that prevents the sand from being able to penetrate the rope.
  • the core comprises a supporting fiber of polyamide or polyester coated by a thermoplastic material such as polyethylene.
  • US4378725 has several drawbacks.
  • the method results in a hollow rope that may fill with sand or small particles when the sealing layer is damaged.
  • the described thermoplastic material does not bind with the heat- shrinkable filaments and leaks out the rope in time. As such the thermoplastic material is only advantageous for a limited time.
  • the core comprises at least two materials, viz. the supporting fiber and the coating, results in a cumbersome manufacturing procedure of the rope.
  • the present invention aims to provide a solution to at least part of these problems. It was found that this objective can be met by a sealed rope comprising an elongated thermoplastic core and yarns arranged around the core in the elongated direction, wherein at least part of the thermoplastic core has at least partly penetrated the voids between the yarns.
  • Figure 1 is a schematic representation of a fishing net in accordance with the present invention.
  • Figure 2 is a schematic representation of a single mesh in accordance with the present invention.
  • Figure 3 is a schematic representation of a particular embodiment of a sealed rope in accordance with the present invention.
  • the yarns may be arranged around the core by braiding, twisting, twining and the like. Such arrangements typically result in voids or openings between the yarns through which and in which the sand may penetrate.
  • the yarns may be of different sizes and shapes.
  • the yarns in accordance with the present invention may be flat yarns, round yarns, tapes, bundles of fibers such as threads, wires and the like.
  • Typical materials for the yarns are polymeric materials such as polyamides, preferably polyamide-6, polyesters, polylactic acid, polyolefins, polypropylene, polyaramid, high-molecular weight polyolefins, such as high- molecular weight polyethylene.
  • the material may however not be limited to polymeric materials.
  • other materials that may be suitable for the yarns are metals, such as stainless steel.
  • the present invention may also apply to wire ropes, e.g. cables.
  • thermoplastic core comprising thermoplastic polyurethane (TPU) is suitable for the present invention.
  • TPU thermoplastic polyurethane
  • Thermoplastic polyurethanes are typically multiphase block copolymers that are based on polyol, diisocyanate, and chain-extender blocks. Depending on the blocks the TPU is based on, TPUs are divided into certain classes such as polyester TPU, polyether TPU or polycaprolactone TPU.
  • thermoplastic core Typical TPU classes that may be used for the thermoplastic core are polyester TPU or polyether TPU. When the yarns comprise nylon, a polyether TPU is preferred.
  • the diisocyanate block of the TPU can be based on either aliphatic or aromatic.
  • the specific TPU class is typically carefully selected to chemically match the yarns arranged around the core in order to have a good adhesion between the yarns and the core after thermo stabilization.
  • TPU commonly comprises soft (typically the polyol block) and hard (typically the extended diisocyanate) blocks.
  • the ratio between the amount of soft-blocks and hard-blocks is typically one of the TPU properties that is important to find said chemical match.
  • Other properties of the TPU that are important in this aspect are the melting temperature and polarity of the TPU.
  • the thermoplastic core and the yarns may comprise materials that have a certain affinity for each other due to e.g. supramolecular interaction. Such materials may thus have a certain affinity for each other at a molecular level, thereby bonding at a molecular level. Without wishing to be bound by theory, such bonding may result from non-covalent interaction such as dipole-dipole interaction, hydrogen bridges, electrostatic interactions between (partially) charged groups, ionic
  • thermoplastic core and the yarns are at least partially bonded at a molecular level.
  • bonded at a molecular level means any type of interaction between the thermoplastic core and the yarns that limits leaking of the core out of the rope.
  • TPU polyamides such as nylon, ethyl vinyl acetate (EVA), thermoplastic elastomers (TPE) and linear low-density polyethylene LLDPE.
  • EVA ethyl vinyl acetate
  • TPE thermoplastic elastomers
  • LLDPE linear low-density polyethylene
  • thermoplastic core is an extruded monofilament.
  • Such a core greatly facilitates the production process of the rope.
  • thermoplastic core comprising TPU is both elastic and strong.
  • thermoplastic core is an extruded monofilament or multifilament of another material than TPU, but is covered with TPU.
  • the maximum breaking force of the thermoplastic core depends on the diameter for the thermoplastic core.
  • diameter is meant the diameter of the core in case the cross-section of the thermoplastic core is circular or an equivalent diameter in case the cross-section of the core is not circular.
  • the equivalent diameter is the diameter of a circle having the same surface area as the non-circular cross-section in question. For instance, when the diameter of the thermoplastic core is 1.6 mm, the thermoplastic core preferably has a breaking force of 6 to 8 kgf.
  • the thermoplastic core has a diameter of more than 1.4 mm and a breaking force of more than 2 kgf as determined by the standardized method DIN EN 527.
  • the diameter of the thermoplastic core may be up to 3 mm.
  • the diameter may be up to 1.8 mm whereby the core may have a breaking force of 15 kgf or less.
  • the thermoplastic core has a diameter of 1.5 to 1.7 mm and a breaking force of 4 to 9 kgf.
  • the preferred mechanical properties, as determined by the standardized method DIN EN 527, may also be expressed by the tensile strength.
  • the tensile strength of the thermoplastic core is more than 12 MPa and preferably less than 58 MPa. More preferably the tensile strength is 22-45 MPa, most preferably 29-39 MPa.
  • the elongation to break of the thermoplastic core is typically 100% to 300%, preferably 120-200%, more preferable 130-150%. Such properties are particular advantageous when the rope is used in fishing nets.
  • the sealed rope according to the present invention may typically be used in fishery, in particular fishing nets, preferably the cod-end of the fishing net may comprise the sealed rope to prevent reduction of the mesh size due to sand penetration in the rope.
  • a particular embodiment of the present invention is a fishing net comprising the sealed rope in accordance with the present invention.
  • sealed rope may also be advantageously used in other fields than fishery.
  • sealed ropes in accordance with the present invention which are limited susceptible for penetration of sand and other small particle and wear may be used in docking boats and ships, platforms, sailing boats, but also in rock-climbing and in for instance construction works and mining applications.
  • any field wherein ropes are exposed to sand and small particles may benefit from the present invention.
  • the rope construction may vary depending on its intended application.
  • the sealed rope in accordance with the present invention may serve as a yarn or strand in the construction of thicker ropes.
  • braided or twisted thicker ropes can be constructed containing more than one rope, e.g. 8, 12, 16, 32 and 48 ropes wherein at least one of the 8, 12, 16, 32 or 48 ropes is a sealed rope in accordance with the present invention.
  • Said more than one ropes of this particular embodiment can surround a further thermoplastic core.
  • a method for producing a sealed rope in accordance with the present invention comprises the steps of:
  • thermoplastic core at least partially melts and at least partially penetrates the voids between the yarns
  • the thermoplastic core may be provided by melting a
  • thermoplastic resin e.g. a resin comprising TPU
  • a monofilament e.g. a tape, yarn or a bundle of multifilaments.
  • a resin comprising TPU e.g. a resin comprising TPU
  • thermoplastic materials that can be used are typically thermoplastic elastomers, preferably thermoplastic
  • TPU polyurethanes
  • Other materials that can be used are e.g. polyolefin or nylon.
  • the rope with the thermoplastic core can be produced by using a standard 8, 12,16, 32 or 48 strands braider that has the capability to receive the core material from an extra position to feed it to the core of the rope during the braiding process.
  • thermoplastic core material is located in the center and the other strands are braided around it.
  • the braiding speed and the speed of feeding of the core may be carefully synchronized, without over- stretching the core. The synchronization prevents tension build up in the final braid.
  • twisted ropes can be produced by twisting the strands around the thermoplastic core.
  • Rope (1) of figure 3 comprises an outer braid (2) that can be produced from 8, 12, 16, 32 or 48 strands of yarn, and a thermoplastic core (3) that is preferably a monofilament, more preferably a monofilament of TPU. At this stage in the process, the thermoplastic core (3) is still able to freely inside the outer braid.
  • the braided rope is cut into several smaller ropes and each rope end is winded on small bobbins to be used in a creel and the bobbins of a loom.
  • the desired configuration of the net may be defined on the netting loom by varying the number of meshes in the length direction, the number of meshes in the width direction, the mesh size, single or double braid/twine and/or single or double knot
  • thermoplastic core may lead to difficulties in the looming process and an unstable production process resulting in a large variation of mesh sizes. It was found that a lower diameter of the thermoplastic core reduces the rigidity of the core and improved production stability.
  • Preferred diameters of the thermoplastic core is in the range of 0.1 to 5 mm, preferably 0.5 to 3 mm, more preferably 1 to 2 mm.
  • the net resulting from the looming that was produced may be submitted to a heat stabilization process in an autoclave under controlled pressure, temperature and water vapor concentration in order to fix the mesh size, by fixation of the knots.
  • This process can be performed with or without tensioning the net in the lengthwise direction.
  • the thermoplastic core of the ropes inside the netting is at least partially melted in a controlled way. Thereby the melted thermoplastic core material partially fills the voids in the hollow braided rope and binds to the inner circle of the hollow braid surrounding the core. This may result in the sealing of the rope inside the netted construction.
  • Knotless nets are being produced by braiding the meshes from the braided, twisted or twined ropes in a circular net braiding machine.
  • the mesh size is the longest distance between two knots when the net is stretched (figure 2).
  • the measuring jaws of the mesh gauge are being placed between the opposite knots and they create a predetermined force, while measuring the distance between these knots.
  • the recommended forces for measurement of the mesh size are 10 N for general netting for all mesh sizes; and more specifically for cod-ends: 20 N for mesh sizes ⁇ 35 mm; 50 N for mesh sizes > 35 mm and ⁇ 55 mm; 125 N for mesh sizes > 55 mm.
  • the mesh stability is the change in mesh size in time during the use of the net.
  • the mesh size is determined before use of the net according to the procedure described above. Subsequently, the mesh size measurement has to be repeated at a specified time interval during the period that the net is in use. The process is repeated as long as the mesh size is still inside the allowed specifications. A soon as the mesh size is lower than allowed, the net is discarded.
  • the invention is illustrated by the following example. Example
  • a TPU comprising monofilament was produced by extruding the polyether TPU through a circular shaped nozzle and stretched 4 times in a two-step process.
  • the TPU monofilament that was hereby produced had a diameter of 1.6 mm and a weight of 2.2 g/m.
  • the net was depth- wise thermostabilized. Adhesion of the TPU monofilament to the outer nylon strands after thermostabilization was good.
