Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fishing line composed of multifilament fibers using an ultrahigh molecular weight polyolefin filament splitting yarn. More specifically, the present invention relates to a lightweight and high-strength fishing line suitable for fishing of sweetfish, hellebuna, and the like.

[0002]

2. Description of the Related Art There are many types of fishing line such as reel line, river fishing line, Harris line, and Otori line which are wound up on a reel. These fishing lines are generally required to have characteristics such as light weight and high strength.

By the way, many conventional fishing lines use monofilament fibers generally called Tegus. This is because it is easy to manufacture while at the same time taking advantage of the property that it is difficult to get entangled and the property that it can be easily rolled up. And, from the fact that it does not have a curling habit, good touch, durability, etc., conventionally, nylon 6,6,6-nylon, 6,10-nylon, polyester, vinylon,
Fiber materials such as polyvinylidene fluoride and metal fibers have been used. Further, as proposed in JP-A-60-164421, a monofilament fishing line for fishing reels made of high molecular weight polyolefin is also known.

[0004]

However, even if the monofilament-like yarn made of a high molecular weight polyolefin proposed in Japanese Patent Laid-Open No. 60-164421 is applied to a fishing line for away such as sweetfish and hebruna. However, there is a problem that the thread is too thick to be applied as it is. That is, the fishing line for the line thread or the needle thread such as the sweetfish and the helluna needs to be much lighter than the fishing line of the known example. Further, if the above-mentioned Japanese Patent Laid-Open No. 60-164421 is simply thinned, it has a problem that it has a twisting tendency because it is in a monofilament shape and has a high modulus (rigidity), which makes it difficult to operate.

Particularly in ayu fishing, as is well known, there is a fishing method called friend fishing, in which a live ayu is tied with a nose ring, released into the water, made into a decoy (bait), and another ayu is attracted and hooked for fishing. Is generally used. In this case, the most important thing is to create a condition in which the decoy sweetfish can swim freely and lively for a long time in a natural state. For this purpose, the fishing line must be thin and light.

From this background, nylon is 0.2
A very thin thread such as No. 0.4 (thread diameter 74 to 104 μm) is mainly used. However, even with a fishing line of this thickness, for the decoy, due to the resistance of the line in water,
It was far from being completely free to move around.

The situation is almost the same for a fishing line made of polyvinylidene fluoride. In addition, recently, tungsten and amorphous metal fibers have been proposed, and even finer fishing lines have become possible, and 0.08-0.175 (49-69μ)
m) There is also a proposal to improve the decoy movement by using a thread. However, the metal fibers have a drawback of being heavy, and for example, the weight of the fishing line of the metal fibers of No. 0.08 is 0.
There is also 0272g / m, which is about 10 made of nylon.
Double the value. Therefore, it is hard to say that the improvement of decoy movement is sufficient.

In order to solve the above-mentioned problems of the prior art, it is an object of the present invention to provide a fishing line which is lightweight, has high strength, is less prone to curling and is easy to operate as a fishing line. More specifically, it is an object of the present invention to provide a fishing line for ayu or hebruna which has a fineness comparable to metal fibers and a light weight equivalent to that of nylon while maintaining high tensile strength.

[0009]

In order to achieve the above object, the fishing line of the present invention is a fishing line composed of ultra-high molecular weight polyolefin filament fiber, and the fishing line is composed of multifilament fibers using split fibers. The total denier is 100 denier or less, and it is assembled into a string and resin-processed .

In the above structure, the number of pitches for assembling the string-shaped fishing line is preferably 200 to 2000 P / m.

[0011]

According to the structure of the present invention, a fishing line composed of ultra-high molecular weight polyolefin filament fibers, wherein the fishing line is composed of multifilament fibers using a splitting yarn, and has a total denier of 100 denier or less, Moreover, it is assembled into a string and is resin-processed.
By that, a high strength light weight, hard to regard also curl, can be realized easily operable fishing line as the fishing line. In particular, the use of split yarn leaves a moderate curl and increases the friction and catching between single yarns when a string is formed by assembling in a later process, and a highly integrated fishing line can be realized. .

Since the fishing line of the present invention is made of an ultra high molecular weight polyolefin filament fiber having a total denier of 100 denier or less, it has a strength of 20 g / denier or more, preferably 30 g / denier or more, which makes it lightweight and high tenacity. Can be used as a fishing line. Next, since the fishing line is composed of multifilament fibers and assembled into a string shape, it is possible to obtain a fishing line that is hard to be rolled and is easy to operate as a fishing line. In other words, the monofilament shape (teguth shape) has a problem that it is difficult to tie like a gut of tennis due to its high modulus (rigidity), the loop becomes large, and a winding habit is easily formed, and once the habit is formed, it is difficult to remove. The above problems can be solved by constructing the single yarn from thin multifilament fiber and assembling it into a string shape.

In the above description, the ultrahigh molecular weight polyolefin filament fiber is made of, for example, ultrahigh molecular weight polyethylene fiber or ultrahigh molecular weight polypropylene fiber, has an average molecular weight of 200,000 or more, and is generally called gel fiber. This fiber can be obtained by a method such as gel spinning / drawing, melt orientation drawing, and solvent swelling drawing.

The preferable total denier in the above is 70 denier or less, particularly preferably 50 denier or less. The preferred number of multifilament fibers is
It is 2 to 5.

In the above description, denier means a fiber length of 9
The weight (unit: gram) per 000 m. Moreover, in the above-mentioned fishing line of the present invention, the number of pitches for assembling the string-shaped fishing line is preferably in the range of 200 to 2000 P / m, and particularly preferably in the range of 400 to 800 P / m. The reason for this is to impart appropriate rigidity and suppleness, and also to make it difficult to be crushed when rubbed in a rocky place, and to impart a characteristic that is easy to operate as a fishing line. When the assembly is adopted, the integration of the multifilaments can be improved more than the twisting. In addition, it is possible to twist up although it does not exhibit the good characteristics as assembled. In this case, the twist number is 100 to 1000 T / m
It is preferably in the range, and more preferably the number of twists in the twisting is in the range of 200 to 700 T / m. The reason for this is to impart appropriate rigidity and suppleness, and also to make it difficult to be crushed when rubbed in a rocky place, and to impart a characteristic that is easy to operate as a fishing line.

If the number of pitches for assembling is less than the above range, the converging property of a plurality of filaments is not sufficient, the appearance is not good, and the fishing line tends to come apart during fishing, and one filament is damaged. The stress is concentrated there and the overall strength is reduced, which is not preferable. Further, if the number of assembled pitches exceeds the above range, the tensile strength and the knot strength tend to be extremely reduced, which is not preferable.

Further, in the above, it is preferable that the surface of the filament fiber is coated with a resin or a colored resin. This is because the resin allows the multifilaments to be integrated and well integrated. Further, the coloring resin is applied, for example, if it is colored in a fluorescent lemon color, it becomes easy to attach and detach the ayu to the nose ring, and it becomes easy to attach the inverted needle or hit the inverted needle. .
Furthermore, there is an advantage that the state of the fishing line in water can be easily identified.

Next, a method for producing the fishing line of the present invention will be described. The method for producing a fishing line of the present invention is a method for producing a fishing line composed of ultra-high molecular weight polyolefin filament fibers, in which multifilament fibers are first divided into monofilament fibers, and then the total denier of the monofilament fibers is 100 denier or less. As described above, a plurality of pieces are prepared, and by assembling them, a string-like shape is obtained, which is used as a fishing line.

In the above-mentioned manufacturing method, it is preferable to kink by heating or applying a resin during or after the assembling step. Further, in the above-mentioned manufacturing method, it is preferable to apply a dye-added resin or a resin not added with a dye to the surface of the cord-shaped fiber after forming the cord.

The operation of the manufacturing method will be described below. In the method of the present invention, first, multifilament fibers are divided into monofilament fibers. The reason for separating fibers is to use multifilament fibers with a total denier of 100 denier or less,
It is difficult to obtain by spinning and drawing in the manufacturing process, and by separating the fibers, an appropriate kink or curl is left, and when it is formed into a string by assembling in a later process, friction between single yarns This is because the fishing line has a high degree of integrity and catches.

Next, a plurality of separated monofilament fibers are prepared so that the total denier is 100 denier or less, and the filaments are assembled into a string to form a fishing line. The reason why the total denier is 100 denier or less is that the fishing line is lightweight and has high strength as described above. Further, the reason why it is composed of multifilament fibers and assembled into a string shape is to impart appropriate rigidity and suppleness, and to impart a characteristic that it is difficult to be rubbed when rubbed on a rocky place and easy to operate as a fishing line. At this time, as described above, the number of pitches for assembling the string-shaped fishing line is 200 to
The range of 2000 P / m is preferable, and the number of assembled pitches is more preferably 400 to 800 P / m.

In the method of the present invention, a kink stopping treatment is performed by heating or applying a resin during or after the step of assembling or applying the twist. By these processing,
It is possible to improve the morphological stability of the fishing line and prevent the fishing line from breaking down due to the rubbing or twisting during fishing, resulting in a decrease in strength.

In the above, the heating temperature is preferably 60 to 90 ° C., and the strength may decrease on the high temperature side. The resin used for the resin processing is selected from polyurethane, epoxy resin, acrylic resin, polyvinyl acetate resin, etc. At this time, coloring can be performed by mixing a pigment or a dye such as a dye in the resin solution. In particular, mixing a dye with a resin is important for coloring because the ultrahigh molecular weight polyolefin filament fiber used in the present invention cannot be dyed by an ordinary method.
