Description

The present invention relates to a fishing line.

  As fishing lines, various fishing lines such as sea fishing and river fishing are commercially available. These fishing lines are required to have water repellency, smoothness and the like. Moreover, it is calculated | required that it is hard to disconnect.

  For example, in carp fishing, a method is used in which a carp is attached to the nose ring at the tip of the underwater thread, and the carp that appears on the rocky field is swallowed by swimming the carp near the rocky field. This is a so-called friend fishing technique. Conventionally, a high specific gravity and high strength tungsten wire has been used for fishing lines so that the seam can smoothly swim to the bottom of the river without much resistance of the water stream (Patent Document 1). Tungsten wire is hard and does not stretch much. For this reason, fishing lines using a single tungsten wire are likely to be curled, entangled, twisted, etc., when the rod is inverted in water. The curling, tangling, twisting, and the like cause the fishing line to break.

  Therefore, a fishing line obtained by braiding a plurality of tungsten wires in a string shape (a fishing line formed by forming a braid using a plurality of tungsten wires) has been devised and used. This fishing line can be curled, entangled, twisted or broken by braiding a plurality of tungsten wires into a string, and each tungsten wire braided when the heel is reversed and the tensile stress on the yarn is removed. It is intended to prevent such as.

  Further, as a fishing line that is more difficult to break, a high-strength fishing line in which polyarylate fiber or the like is used for the core wire and a tungsten wire is knitted in a string shape on the outer periphery has been devised and used.

  However, since these fishing lines are made of braided tungsten wire, the surface has irregularities and is inferior in smoothness (slip). When such a poorly smooth fishing line is used, for example, for fishing for cormorants, curling or the like tends to occur when the mark is adjusted (moved). In addition, there is a problem that during actual fishing, the fishing line causes troubles such as entanglement and breaks. In addition, there is a problem in that the activity of the kite is hindered, such as unevenness on the surface of the fishing line receives water resistance, and the kite cannot smoothly swim to the bottom of the river.

Therefore, development of a fishing line that is less likely to cause curling, entanglement, twisting, disconnection, etc. in addition to smoothness and water repellency is desired.
JP-A-3-216139

In addition to having smoothness and water repellency, the present invention has curls, tangles, twists,
The main purpose is to provide fishing lines that are less likely to break.

  As a result of intensive studies, the present inventor has found that a fishing line having a specific configuration can achieve the above object, and has completed the present invention.

That is, the present invention relates to the following fishing line for fishing rods.
1. A fishing line formed by coating the outer peripheral portion of a tungsten wire assembly formed by braiding a plurality of tungsten wires with a resin layer containing a fluororesin,
A fishing line in which the resin layer covers each tungsten wire constituting the aggregate.
2. Item 2. The fishing line according to Item 1, wherein the tungsten wire has a diameter of 8 to 30 µm, and the fishing line has a diameter of 20 to 150 µm.
3. Item 3. The fishing line according to Item 1 or 2, wherein the resin layer covering each tungsten wire has a thickness of 0.1 to 10 µm.
4). Item 4. The fishing line according to any one of Items 1 to 3, wherein the aggregate includes polyarylate fiber, polyethylene fiber, or polyamide fiber as a core wire.
5. Item 5. The fishing line according to Item 4, wherein the core wire has a diameter of 5 to 50 denier.
6). Item 6. The fishing line according to any one of Items 1 to 5, which is a fishing line for fishing rods.

  Although the fishing line of the present invention uses a tungsten wire, the fishing line is less likely to be entangled, twisted or disconnected during actual fishing. Therefore, the fishing line of the present invention can be used repeatedly.

  The fishing line of the present invention is excellent in water repellency. In particular, when used as a fishing line for kite fishing, the activity of the kite attached to the nose ring can be suitably maintained.

  Furthermore, the fishing line of the present invention is excellent in smoothness (slip). For example, when adjusting the mark in carp fishing, the thread can be prevented from curling, and troubles such as thread entanglement and wire breakage can be suitably avoided.

Fishing line The fishing line of the present invention is a resin containing a fluororesin at the outer periphery of a tungsten wire assembly formed by braiding a plurality of tungsten wires into a string shape (formed by braiding a plurality of tungsten wires into a string shape). A fishing line coated with a layer,
The resin layer covers each tungsten wire constituting the aggregate.

(Tungsten wire assembly)
In the fishing line of the present invention, a tungsten wire aggregate formed by braiding a plurality of tungsten wires in a string shape is coated with a resin layer.

  By using a tungsten wire having a high specific gravity as a constituent material, a fishing line having an appropriate settling property can be obtained. Such a fishing line is advantageous, for example, for fishing for carp.

  The diameter of the tungsten wire is preferably about 8-30 μm, more preferably about 10-20 μm. By using a tungsten wire having a diameter of about 8 to 30 μm, a flexible, thin and sufficient strength fishing line can be suitably obtained while using a tungsten wire. Such a fishing line is most suitable for, for example, fishing for cormorants.

The tensile strength of the tungsten wire is preferably about 2000 to 5000 N / mm ² .

  By braiding the plurality of tungsten wires in a string shape, twisting, entanglement, etc. of the fishing line can be suitably prevented.

  The aggregate is a braided wire formed by braiding a plurality of the tungsten wires into a string shape. Specifically, each tungsten wire is braided so as to be positioned at an angle other than 0 ° or 90 ° with respect to the length direction of the aggregate to be formed.

  The pitch of the aggregate is preferably 0.9 to 2.8 mm, and more preferably 1.3 to 2.4 mm. When the pitch is 2.8 mm or less, fishing line entanglement, twisting, disconnection, and the like can be more effectively prevented. Moreover, when exceeding 2.8 mm, the merit by braiding in string shape cannot fully be enjoyed. Specifically, when the pitch exceeds 2.8 mm, the fishing line cannot sufficiently exhibit flexible elongation, and is close to a tungsten single wire, so that disconnection due to metal fatigue is likely to occur.

  When the pitch is less than 0.9 mm, the tungsten wire may be broken when the tungsten wire is braided on a braiding machine.

  The pitch means the axial length of one complete rotation of a spiral formed by one tungsten wire in the assembly.

  The number of tungsten wires to be braided is not particularly limited, and is 2 to 32, preferably 4 to 16, more preferably 4, 8, and 16.

  The aggregate may include polyarylate fiber, polyethylene fiber, or polyamide fiber as a core wire as necessary. By including the fiber as a core wire, twisting, entanglement and the like are less likely to occur. Moreover, the strength of the fishing line can be improved. For example, in the fishing of sharks generally performed after mid-August, the target shark may grow to, for example, 150 g or more. In this kind of carp fishing, it is preferable that the aggregate includes the core wire.

  The diameter of the core wire is preferably 5 to 50 denier, and more preferably 10 to 40 denier. By setting the diameter of the core wire to 5 denier or more, the strength of the fishing line can be more reliably improved. By making the diameter of the core wire 50 denier or less, it becomes easy to realize a thin fishing line.

(Resin layer containing fluororesin)
The fishing line of the present invention is formed by covering the outer periphery of the aggregate with a resin layer containing a fluororesin. In particular, in the fishing line of the present invention, the resin layer covers each tungsten wire constituting the aggregate. That is, the resin layer covers the periphery of each of the plurality of tungsten wires in the aggregate. Thereby, each tungsten wire which comprises the said assembly becomes easy to move (it is easy to disperse | distribute), for example, it can prevent reliably the tangle of the thread | yarn at the time of carp fishing, a twist, a disconnection, etc.

  By covering with a resin layer containing a fluororesin, excellent water repellency and smoothness can be imparted to the fishing line. For example, when fishing for friends, the fishing line (underwater thread) does not receive great resistance to water flow at the bottom of the river, which is the main activity area of the carp, so that the carp attached to the nose ring can swim smoothly. That is, the fishing rod attached to the nose ring is less likely to get tired in the water and can move freely and actively for a long time. Further, since the smoothness of the fishing line is improved, problems such as curling of the fishing line during the adjustment of the mark are unlikely to occur. Therefore, by using the fishing line, even beginners can easily perform fishing for carp.

  For example, when an acrylic resin or the like is used instead of the fluororesin, the tungsten wire in the aggregate is not sufficiently dispersed, and the fishing line is easily broken.

  Note that “break apart” means, for example, that each metal wire inside is unwound while maintaining the shape of the fishing line, as shown in <Fishing line of Example 1> in FIG.

  By separating each tungsten wire, even if the fishing line is curled, twisted or tangled, it becomes difficult to break the wire.

  Examples of the fluororesin include polytetrafluoroethylene (PTFE), tetrafluoroerylene / perfluoroalkyl vinyl ether copolymer (PFA), tetrafluoroethylene / hexafluoropropylene copolymer (FEP), and tetrafluoroethylene / ethylene. Examples thereof include a copolymer (ETFE), polyvinylidene fluoride (PVDF), polychlorotrifluoroethylene (PCTFE), and chlorotrifluoroethylene / ethylene copolymer (ECTFE). These fluororesins can be used alone or in combination of two or more. In particular, it is preferable to use PTFE as the fluororesin.

  The content of the fluororesin contained in the resin layer is preferably 10 to 50% by weight.

In addition to the fluororesin, the resin layer may further contain a known additive generally used in the field of fluororesin coating. Examples of the additive include acrylic resins.
The thickness of the resin layer covering each tungsten wire is preferably 10 μm or less, more preferably 0.1 to 10 μm, and further preferably 0.5 to 10 μm. When the thickness of the resin layer is 10 μm or less, the gap between the tungsten wires is effectively prevented from being filled with the resin layer, and the tungsten wires are easily separated. As a result, fishing line entanglement, twisting, disconnection, and the like can be effectively prevented. For example, when the fishing line of the present invention is used for fishing of a kite, even if the kite attached to the nose ring is reversed, the fishing line can be effectively prevented from being entangled, twisted or disconnected.
In addition, by setting the thickness of the resin layer to 0.1 μm or more, the present invention is preferably performed while avoiding problems such as a portion where the resin layer does not exist around the aggregate (each tungsten wire). Can be produced.
The diameter of the fishing line of this invention is 20-150 micrometers normally, Preferably it is 30-90 micrometers.

  The fishing line of the present invention can be used for sea fishing, river fishing and the like. In particular, the fishing line of the present invention is preferably used for river fishing, and more preferably used for fishing for carp friends. When used for fishing for cormorants, it can be suitably used as an underwater thread.

Production method of fishing line The production method of the fishing line of the present invention is not particularly limited, and known methods may be appropriately combined. For example, the fishing line of the present invention can be manufactured by forming the aggregate by braiding a plurality of the tungsten wires into a string shape, and then covering the outer periphery of the aggregate with the resin layer.

  As a means for braiding the tungsten wire, for example, a known braiding machine may be used.

  As a method of coating the outer peripheral portion of the aggregate with the resin layer, a known coating method such as dip coating, spray coating, or electrodeposition coating can be employed. In particular, the fishing line of the present invention is produced by a method in which an electrodeposition coating is formed by performing electrodeposition coating on the assembly using the electrodeposition coating containing the fluororesin, and then the coating is baked. did. By performing electrodeposition coating, the resin layer can be suitably formed for each tungsten wire constituting the aggregate.

  The method for electrodeposition coating is not particularly limited, and a known method may be followed. Known methods include methods described in JP-B-6-55913, JP-A-2005-29913, and the like.

  Although the density | concentration of the said fluororesin in the said electrodeposition coating material is not specifically limited, 10 to 50 weight% is preferable and 20 to 40 weight% is more preferable. When the concentration of the fluororesin is within such a range, the thickness of the resin layer can be suitably adjusted to 0.1 to 10 μm.

  In addition, the electrodeposition paint may contain a solvent such as isopropyl alcohol or butyl cellosolve or a known additive generally used for an electrodeposition paint, if necessary.

  The coating voltage is preferably 10 to 150 v, more preferably 10 to 70 v. When the coating voltage is 10 to 150 V, the thickness of the resin layer can be suitably adjusted to 0.1 to 10 μm.

  The coating time is preferably 1 to 5 minutes, and more preferably 2 to 3 minutes. The baking temperature is preferably 100 to 400 ° C, more preferably 150 to 250 ° C. The baking time is preferably 10 to 60 minutes, more preferably 20 to 50 minutes. In the case where the electrodeposition coating voltage, time, baking temperature, and time are required, the thickness of the resin layer can be suitably adjusted to 0.1 to 10 μm.

Hereinafter, the present invention will be described in more detail using examples and comparative examples. However, the present invention is not limited to the following examples.
In addition, about the thickness of the fluorine-type resin layer, it confirmed using the electron microscope.

Example 1
Using a braiding machine (product name “Eight Blader” manufactured by Kokbun Limited), a tungsten wire assembly was produced by braiding eight tungsten wires having a diameter of 12 μm into a string shape (pitch 1.9 mm).
Next, an electrodeposition coating film was formed by performing electrodeposition coating on the obtained assembly. The electrodeposition paint used was a trade name “Elecoat Nicelon” manufactured by Shimizu Corporation (containing PTFE as a fluororesin). The coating conditions are as follows.
(Painting conditions)
・ Painting voltage: 10v
-Coating time: 3 minutes Thereafter, the formed electrodeposition coating film was baked (baking temperature 200 ° C and baking time 40 minutes) to produce a fishing line having a diameter of 39 µm.
In the obtained fishing line, each tungsten wire was covered with a PTFE-containing resin layer (PTFE: 25% by weight), and the thickness of the resin layer was 1 μm.
Example 2
Instead of a tungsten wire having a diameter of 12 μm, a tungsten wire having a diameter of 11 μm is used, and a polyarylate fiber having a diameter of 10 denier (product name “Vectran” Kuraray) is used so that the polyarylate fiber becomes the core. A fishing line having a diameter of 52 μm was produced in the same manner as in Example 1 except for braiding (pitch 1.9 mm).
In the obtained fishing line, each tungsten wire was covered with a PTFE-containing resin layer (PTFE: 25 wt%), and the thickness of the resin layer was 1 μm.
Comparative Example 1
A fishing line having a diameter of 70 μm was prepared by forming an electrodeposition coating film on a tungsten single wire having a diameter of 56 μm by the same method as in Example 1.
The thickness of the coating film (resin layer) was 7 μm. The PTFE content in the coating film (resin layer) was 25% by weight.

Comparative Example 2
A fishing line was prepared in the same manner as in Example 1 except that an electrodeposition paint containing an acrylic resin was used instead of PTFE, and the thickness of the resin layer formed by the paint was 3 μm. The diameter of the fishing line made: 43 μm).
