【発明の属する技術分野】
本発明は、スベリ性が良くてガイドとの摩擦抵抗が低く、インナーガイド竿を使った場合でも仕掛けの飛距離を出すことが可能であるばかりか、自然に仕掛を流すことができ、スピニングリールに巻いて使った場合でも糸よれが入りにくく、ライントラブルを起こさない釣り糸に関するものである。
【0002】
【従来の技術】
従来の釣り糸としては、断面が円形の合成樹脂モノフィラメントが主流を占めていたが、最近では、断面が楕円形の合成樹脂モノフィラメントや、糸の長手方向に沿って複数本の溝を形成した形状の合成樹脂モノフィラメントなどの異形断面モノフィラメントからなる釣り糸も市場にでまわっている。
【0003】
しかるに、最近では、釣り場の多様化、釣り竿の多様化および釣り技術の進歩などに応じて、スベリ性が良く、糸と釣り糸ガイドとの摩擦抵抗が低く、かつスピニングリールに巻いて使ったときに糸よれの発生を起こしにくい釣り糸の実現が望まれている。
【0004】
すなわち、釣り糸を実用するに際して、例えば釣り竿の中を釣り糸が通るいわゆるインナーガイドの竿を使って磯釣りをした場合には、竿の構造上釣り糸が擦過する釣り糸ガイド部分が極端に多くなってしまうため、従来の釣り糸では、ガイドと釣り糸の摩擦抵抗が大きくなり、軽い仕掛けを遠くへ投げようとした場合の遠投性が悪くなってしまうという問題があったからである。さらに、仕掛けを潮に乗せて流していく場合には、釣竿からの糸の出が悪くて仕掛けを引っ張ってしまいうため、仕掛けをうまく流していけなくなり、結果として仕掛けがポイントからずれてしまい、極端に釣果が落ちてしまうという問題もあった。
【0005】
また、釣り糸をスピニングリールに巻いて使う場合には、縦方向に糸を引きだし、横方向に糸を巻き取るといったスピニングリールの構造上、従来の釣り糸では、数時間から数回使用すると糸に撚りが入ってしまう現象、いわゆる糸よれと呼ばれる現象を招くいう問題があり、糸よれにより仕掛けが絡んでしまったり、釣り糸がリール、釣り竿に絡んで最悪の場合は高価な釣り竿を折ってしまうという不具合を生じていたのである。
【0006】
このような場合、もし従来の釣り糸よりもスベリ性が良くて糸と釣り糸ガイドとの摩擦抵抗が低く、かつスピニングリールに巻いて使ったときに糸よれの発生を押さえた釣り糸を開発することができれば、これをインナーガイド竿を使った場合でも仕掛けの飛距離がアップするばかりか、仕掛けを自然に流していくことが可能となって釣果がアップするばかりか、糸よれによるライントラブルも解消して、終日快適な釣りの実現を期待することができる。
【0007】
糸と釣り糸ガイドとの摩擦抵抗を下げることを目的とした釣り糸方法としては、糸の長手方向に沿って複数本の溝を形成した断面形状のモノフィラメントからなる釣り糸(特許文献1参照)、および上記釣り糸の摩擦係数を低くするために釣り糸表面にシリコンオイルなどの平滑剤が塗布された釣り糸(特許文献2参照)などが提案されているが、前者の釣り糸では、糸の表面に形成された凹凸によって糸とガイドの接点を小さくすることができるものの、線接触によるため摩擦抵抗を十分に下げることができず、後者の釣り糸では、平滑剤が使用中に剥がれてしまうために、摩擦抵抗軽減効果の耐久性に劣るという問題があった。

【発明が解決しようとする課題】
本発明は、上述した従来技術における問題点の解決を課題として検討した結果達成されたものである。
【0010】
したがって、本発明の目的は、スベリ性が良くてガイドとの摩擦抵抗が低く、インナーガイド竿を使った場合でも仕掛けの飛距離を出すことが可能であるばかりか、自然に仕掛を流すことができ、スピニングリールに巻いて使った場合でも糸よれが入りにくく、ライントラブルを起こさない釣り糸を提供することにある。
【0011】
【課題を解決するための手段】
上記の目的を達成するために、本発明の釣り糸は、合成樹脂を溶融紡糸してなる単糸繊度220dtex以上2600dtex以下の異形断面モノフィラメントの長手方向に撚りを掛けて熱セットしたねじりモノフィラメントからなることを特徴とする。
【0012】
なお、本発明の釣り糸においては、
前記ねじりモノフィラメントの表面が螺旋状の凹凸を形成していること、
前記合成樹脂が、ポリアミド系樹脂、フッ素系樹脂およびポリエステル系樹脂から選ばれた少なくとも1種であること、

前記ねじりモノフィラメントの断面形状が、三角形、四角形、五角形、六角形、クローバー型、多葉型および星形から選ばれたいずれか1種であること
が、いずれも好ましい条件であり、これらの条件を満たすことによって一層優れた効果の取得を期待することができる。
【0013】
【発明の実施の形態】
以下に、本発明釣り糸の構成および効果について詳述する。
【0014】
本発明の釣り糸は、合成樹脂を溶融紡糸してなる単糸繊度220dtex以上2600dtex以下の異形断面モノフィラメントの長手方向に撚りを掛けて熱セットされたねじりモノフィラメントからなるものであり、糸の表面が螺旋状の凹凸を形成していることが重要な要件であり、かかる要件を満たすことによって、優れたスベリ性を発現すると共に、糸よれが軽減するという優れた特性を発揮することができる。
【0015】
すなわち、本発明の釣り糸は、糸の表面に螺旋状の凹凸を有しているため、ガイドとの接触が点接触となってスベリ性が向上し、ガイドとの抵抗が低くなり、遠投性を向上できるばかりか、仕掛けを自然に流していくことができるという優れた効果を発揮することができる。
【0016】
本発明の釣り糸の構成素材(合成樹脂)としては、溶融紡糸可能な熱可塑性樹脂であれば特に制限はないが、なかでもポリアミド系樹脂、フッ素系樹脂およびポリエステル系樹脂から選ばれた少なくとも1種が好ましく使用される。
【0017】
上記ポリアミド系樹脂の具体例としては、ナイロン6、ナイロン66、ナイロン610、ナイロン612、ナイロン11ナイロン12およびこれら各種ナイロンの相互共重合体などが挙げられる。
【0018】
上記フッ素系樹脂の具体例としては、ポリフッ化ビニリデン、エチレン−テトラフルオロエチレン共重合体、ポリテトラフルオロエチレン、テトラフルオロエチレン−フッ化ビニリデン共重合体、パーフルオロアルコキシ樹脂、テトラフルオロエチレン−ヘキサフルオロプロピレン共重合体、テトラフルオロエチレン−ヘキサフルオロプロピレン−フッ化ビニリデン共重合体およびエチレンクロライド−テトラフルオロエチレン共重合体などが挙げられる。、
上記ポリエステル系樹脂の具体例としては、ポリエチレンテレフタレート、ポリブチレンテレフタレート、ポリプロピレンテレフタレートなどの芳香族ポリエステル、およびポリ乳酸、ポリブチレンサクシネートなどの脂肪族ポリエステルなどが挙げられる。
【0019】
本発明の釣り糸を形成するねじりモノフィラメントは、上記合成樹脂を通常の方法で異形断面口金を使用して溶融紡糸し、必要に応じて延伸した後、この異形断面モノフィラメントの長手方向に撚りを掛けて熱固定することにより得られるが、この場合の撚りピッチは30〜90ターン/10cm程度であることが好ましい。
【0020】
なお、異形断面モノフィラメントの形態としては、一成分系のモノフィラメント以外にも、海島複合、二重芯鞘複合、三重芯鞘複合などの複合モノフィラメントの形態を選択することもできる。
【0021】
また、異形断面モノフィラメントの断面形状としては、三角形、四角形、五角形、六角形、クローバー型、多葉型および星形などが挙げられ、特にモノフィラメントの外周長手方向に3〜15条の溝を有する3葉〜15葉の多葉型の場合には、綺麗な螺旋形状を形成することができる。
【0022】
さらに、特に限定するものではないが、撚りの方向は、スピニングリールにより釣り糸に発生する撚りと反対方向、つまりZ方向の撚りであることが、糸よれを軽減する上でより安定した性能を発現できることから好ましい。
【0023】
このようにして得られるねじりモノフィラメントは、その引張強度が500MPa以上、好ましくは550MPa以上であることが、釣り糸として使用されたときに高い強度を発現することから望ましいといえる。
【0024】
本発明の釣り糸は、目的とする特性を阻害しない範囲であれば、例えば顔料、染料、結晶化抑制剤、金属化合物、比重調整剤、撥水処理剤、親水処理剤、酸化チタンおよび可塑剤などの添加剤を含有することができる。
【0025】
かくしてなる本発明の釣り糸によれば、スベリ性が良くてガイドとの摩擦抵抗が低く、インナーガイド竿を使った場合でも仕掛けの飛距離を出すことが可能であるばかりか、自然に仕掛を流すことができ、スピニングリールに巻いて使った場合でも糸よれが入りにくく、ライントラブルを起こさないという優れた効果の発現を期待することができる。

【0033】
次いで、上記異形断面モノフィラメントを、リング撚糸機を使いZ方向に60ターン/10cm掛け、さらに180℃の不活性気体中で1.0倍の熱セットを施し、仕上げ油剤として竹本油脂(株)製TRN−190を付与することにより、異形断面モノフィラメントの長手方向に撚りを掛けて熱セットしたねじりモノフィラメントからなる釣り糸を得た。

【0037】
表1の結果から明らかなように、本発明の釣糸(実施例1〜4)は、長手方向の撚り、熱セットとも実施していない(比較例1)の釣り糸に比べ、実釣評価−1で示される糸のスベリ性に優れるばかりか、実釣評価−2で示される糸よれ性にも優れており、経時による遠投性、仕掛けの流し易さなどに変化なく、糸よれによるライントラブルの発生もなく終日快適に使える釣り糸として、必要十分な効果を発現することができた。
【0038】
一方、多葉型断面であっても長手方向に撚りを掛けていない釣り糸(比較例2)の場合は、釣り糸の実釣評価−1で示されるスベリ性、実釣評価−2で示される糸よれ性がいずれも改善されておらず、経時と伴に低下してしまい半日使ったところで遠投性、仕掛けの流し易さなどが低下し、糸よれがひどくなってしまったばかりか、絡まった糸が竿先に引っかかり竿を折ってしまった。
【0039】
さらに、長手方向の撚りを掛けたが熱セットをしていない釣り糸(比較例3)の場合は、すでに糸よれが入った状態になっており、リールに糸を巻き取る段階で糸が絡んでしまったため、実釣評価で使用してもらうことができなかった。
【0040】
糸の断面形状を丸断面にした釣り糸(比較例4)の場合は、実釣評価−2で示す糸よれ性については改善されているが、実釣評価−1で示すスベリ性についてはガイドとの接点が線接触になることから改善されておらず、経時と伴に遠投性、仕掛けの流し易さが悪くなったばかりか、ポイントに仕掛けを入れることが困難で極端に釣果が悪くなってしまった。
【0041】
また、単糸繊度が細すぎる釣り糸(比較例5)の場合は、絶対強力が不足してしまうため、磯釣り用の道糸として使用するには不適当であり、単糸繊度が太すぎる釣り糸(比較例6)の場合は、曲げ硬さで示される糸の剛直性が強くなり、スプールから糸が自然に解れてしまい、スピニングリールに巻いて使うには不適当な糸になってしまった。
【0042】
【発明の効果】
以上説明したように、本発明の釣り糸は、スベリ性が良くてガイドとの摩擦抵抗が低く、インナーガイド竿を使った場合でも仕掛けの飛距離を出すことが可能であるばかりか、自然に仕掛を流すことができ、スピニングリールに巻いて使った場合でも糸よれが入りにくく、ライントラブルを起こさないという優れた効果を発現するものである。[0001]
BACKGROUND OF THE INVENTION
The present invention has a good sliding property and a low frictional resistance with the guide. Not only can the flying distance of the mechanism be obtained even when the inner guide rod is used, but the mechanism can be flown naturally, and the spinning reel It is related to fishing line that does not easily cause string twist even when wound around and does not cause line trouble.
[0002]
[Prior art]
As conventional fishing lines, synthetic resin monofilaments with a circular cross section dominate, but recently, synthetic resin monofilaments with an elliptical cross section or a shape in which a plurality of grooves are formed along the longitudinal direction of the thread. Fishing lines made of irregular cross-section monofilaments such as synthetic resin monofilaments are also on the market.
[0003]
However, recently, according to diversification of fishing grounds, diversification of fishing rods, and advancement of fishing technology, etc., the smoothness is good, the friction resistance between the line and the line guide is low, and it is used when wound on a spinning reel. Realization of a fishing line that is less likely to cause twisting is desired.
[0004]
That is, when a fishing line is put into practical use, for example, when fishing is performed using a so-called inner guide rod through which the fishing line passes through the fishing rod, the fishing line guide portion on which the fishing line is abraded becomes extremely large due to the structure of the fishing rod. Therefore, the conventional fishing line has a problem that the frictional resistance between the guide and the fishing line is increased, and the long throwing property is deteriorated when a light mechanism is thrown away. In addition, when the mechanism is carried on the tide, the thread from the fishing rod is poor and pulls the mechanism, so the mechanism can not flow well, and as a result, the mechanism deviates from the point, There was also a problem that the fishing results would drop extremely.
[0005]
Also, when fishing line is wound on a spinning reel, the conventional fishing line can be twisted into the line when it is used for several hours to several times due to the structure of the spinning reel, which draws the line in the vertical direction and winds the line in the horizontal direction. The problem is that it causes a phenomenon called so-called thread twisting, which causes the mechanism to get entangled by the thread twisting, or the fishing line to entangle with the reel or fishing rod, and in the worst case, break the expensive fishing rod It was producing.
[0006]
In such a case, it is possible to develop a fishing line that has better smoothness than conventional fishing lines, has low frictional resistance between the line and the fishing line guide, and suppresses the occurrence of twisting when used on a spinning reel. If possible, this will not only increase the flying distance of the mechanism even when using the inner guide rod, it will allow the mechanism to flow naturally and the fishing results will improve, and line troubles due to thread twist will also be eliminated Therefore, it can be expected to realize comfortable fishing throughout the day.
[0007]
As a fishing line method for reducing the frictional resistance between the line and the fishing line guide, a fishing line made of a monofilament having a cross-sectional shape in which a plurality of grooves are formed along the longitudinal direction of the line (see Patent Document 1), and the above-mentioned In order to reduce the friction coefficient of the fishing line, a fishing line in which a smoothing agent such as silicon oil is applied to the surface of the fishing line has been proposed (see Patent Document 2). However, the former fishing line has irregularities formed on the surface of the line. Although the contact between the line and the guide can be reduced by this, the frictional resistance cannot be lowered sufficiently due to the line contact, and the latter fishing line peels off during use, so the frictional resistance is reduced. There was a problem of poor durability.
[0008]

[Problems to be solved by the invention]
The present invention has been achieved as a result of studying the solution of the problems in the prior art described above as an issue.
[0010]
Therefore, the object of the present invention is not only to have a smoothness and low frictional resistance with the guide, but also to be able to obtain the flying distance of the device even when the inner guide rod is used. It is possible to provide a fishing line that is difficult to get twisted even when wound on a spinning reel and does not cause line trouble.
[0011]
[Means for Solving the Problems]
In order to achieve the above object, the fishing line of the present invention comprises a twisted monofilament that is heat-set by twisting in the longitudinal direction of a monofilament monofilament having a single yarn fineness of 220 dtex or more and 2600 dtex or less obtained by melt spinning a synthetic resin. It is characterized by.
[0012]
In the fishing line of the present invention,
The surface of the twisted monofilament forms spiral irregularities;
The synthetic resin is at least one selected from a polyamide-based resin, a fluorine-based resin, and a polyester-based resin;
The tensile strength of the twisted monofilament measured according to JIS L1013 is 500 MPa or more, particularly 550 MPa or more, and the sectional shape of the twisted monofilament is triangular, quadrangular, pentagonal, hexagonal, clover type, multileaf type And any one selected from star shapes is a preferable condition, and by satisfying these conditions, acquisition of a more excellent effect can be expected.
[0013]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, the configuration and effects of the fishing line of the present invention will be described in detail.
[0014]
The fishing line of the present invention is composed of a twisted monofilament that is heat-set by twisting in the longitudinal direction of a monofilament monofilament having a single yarn fineness of 220 dtex or more and 2600 dtex or less formed by melt spinning a synthetic resin, and the surface of the yarn is spiral. It is an important requirement to form a concavo-convex shape, and by satisfying such a requirement, it is possible to exhibit excellent sliding properties and to exhibit excellent characteristics of reducing yarn twisting.
[0015]
That is, since the fishing line of the present invention has spiral irregularities on the surface of the line, the contact with the guide becomes a point contact, the smoothness is improved, the resistance with the guide is reduced, and the long throwing property In addition to improving the performance, it is possible to exert an excellent effect that the device can be flown naturally.
[0016]
The constituent material (synthetic resin) of the fishing line of the present invention is not particularly limited as long as it is a thermoplastic resin that can be melt-spun, and among them, at least one selected from polyamide resins, fluorine resins, and polyester resins Are preferably used.
[0017]
Specific examples of the polyamide-based resin include nylon 6, nylon 66, nylon 610, nylon 612, nylon 11 nylon 12, and various copolymers of these nylons.
[0018]
Specific examples of the fluorine resin include polyvinylidene fluoride, ethylene-tetrafluoroethylene copolymer, polytetrafluoroethylene, tetrafluoroethylene-vinylidene fluoride copolymer, perfluoroalkoxy resin, tetrafluoroethylene-hexafluoro. Examples thereof include a propylene copolymer, a tetrafluoroethylene-hexafluoropropylene-vinylidene fluoride copolymer, and an ethylene chloride-tetrafluoroethylene copolymer. ,
Specific examples of the polyester resin include aromatic polyesters such as polyethylene terephthalate, polybutylene terephthalate, and polypropylene terephthalate, and aliphatic polyesters such as polylactic acid and polybutylene succinate.
[0019]
The twisted monofilament forming the fishing line of the present invention is obtained by melt-spinning the above synthetic resin using a modified cross-section die by a usual method, stretching as necessary, and then twisting in the longitudinal direction of the modified cross-section monofilament. Although obtained by heat setting, the twist pitch in this case is preferably about 30 to 90 turns / 10 cm.
[0020]
In addition to the monocomponent monofilament, the monofilament monofilament may be selected from composite monofilaments such as sea-island composite, double-core sheath composite, and triple-core sheath composite.
[0021]
Examples of the cross-sectional shape of the irregular-shaped monofilament include a triangle, a quadrangle, a pentagon, a hexagon, a clover shape, a multi-leaf shape, and a star shape. In particular, the monofilament has 3 to 15 grooves in the longitudinal direction of the outer periphery of the monofilament. In the case of a multileaf type of leaves to 15 leaves, a beautiful spiral shape can be formed.
[0022]
Furthermore, although not particularly limited, the twisting direction is opposite to the twisting generated in the fishing line by the spinning reel, that is, the twisting in the Z direction, so that more stable performance is exhibited in reducing yarn twisting. It is preferable because it is possible.
[0023]
It can be said that the twisted monofilament thus obtained has a tensile strength of 500 MPa or more, and preferably 550 MPa or more because it exhibits high strength when used as a fishing line.
[0024]
The fishing line of the present invention is, for example, a pigment, a dye, a crystallization inhibitor, a metal compound, a specific gravity adjuster, a water repellent agent, a hydrophilic agent, a titanium oxide and a plasticizer as long as it does not impair the desired properties. The additive may be contained.
[0025]
Thus, according to the fishing line of the present invention, the smoothness is good, the frictional resistance with the guide is low, and even when the inner guide rod is used, the flying distance of the device can be obtained, and the device can flow naturally. Therefore, even when wound on a spinning reel, it can be expected that the yarn will not get twisted and an excellent effect of not causing line troubles can be expected.
[0026]
【Example】
Next, although this invention is demonstrated based on an Example, evaluation of various characteristics was performed according to the following method.

That is, after leaving the sample taken in a cage shape to stand in an atmosphere of 20 ° C. and 65% RH for 24 hours, using a “Tensilon” RTM500 type tensile tester manufactured by Orientec Co., Ltd., yarn length: 250 mm, tensile speed: 300 mm / The tensile strength at break (N) measured under the condition of minutes was divided by the cross-sectional area to obtain the strength (MPa).
[Fineness]
It carried out according to the definition of JISL1013. That is, 20 samples of 90 cm were taken, the absolute dry mass was measured using a METTLER AE240 manufactured by Siebel Machinery Co., Ltd., and the fineness (dtex) was calculated by the following formula.
[0027]
dtex = 10000 × weight of material / length of material × (100 + official moisture content) / 100
[Bending hardness]
The material cut to 50 mm length is left in a temperature and humidity control room at 20 ° C. and 65% HR for 24 hours, and then set on a stainless steel rod with a diameter of 2 mm set at an interval of 10 mm and placed at the center. A stainless steel hook having a diameter of 2 mm was hung and the maximum bending stress (CN) when pulled out at a take-up speed of 50 mm / min was measured using a “TCM-200 universal tensile / compression tester” manufactured by Minebea Co., Ltd.
[Actual fishing evaluation-1]
We asked several anglers to use the inner guide rod and actually used the fishing line of the present invention and the conventional fishing line, and compared the long throwing ability of the device, the ease of flowing the device, etc. It was a feeling evaluation and was evaluated according to the following criteria.
[0028]
○… The long throwing ability of the thread all day and the ease of pouring the device were good, and it was possible to fish comfortably, and a satisfactory fishing result was obtained.
[0029]
X: The long throwing property and the ease of pouring of the device deteriorated with time, and it became difficult to flow the device to the target point, and a satisfactory fishing result could not be obtained.
[Actual fishing evaluation-2]
Feeling that asked the fishing line of several people, using the inner guide rod, actually using the fishing line of the present invention and the conventional fishing line, and comparing the occurrence situation of the yarn twisting trouble by fishing with a ball spinning spinning reel This is an evaluation and was evaluated according to the following criteria. ○… I was able to fish comfortably without any yarn twisting throughout the day.
[0030]
X: The yarn was twisted and the mechanism became tangled, and it was forced to remake the mechanism, or the thread tangled on the tip of the hook was caught and the expensive fold was broken.
[0031]
[Example 1]
30% by weight of nylon 66 resin (M3001C ... relative viscosity 2.95) manufactured by Toray Industries, Inc. was added to the copolymer polyamide resin (M61021H4 ... relative viscosity 4.65) manufactured by Toray Industries, Inc. and stirred and blended. The product is fed to an extruder-type spinning machine, melted at a temperature of 290 ° C., extruded through a die having a 12-leaf multileaf type cross-sectional shape with a hole diameter of 1.0 mm, and immediately cooled and solidified in a cold water bath at 10 ° C. An undrawn yarn was obtained.
[0032]
The undrawn yarn was continuously drawn in the first stage drawing condition: 3.8 times in water vapor at 100 ° C., and then the second stage condition: 1.55 times in an inert gas at 226 ° C. (total draw ratio) (5.9 times), and then a heat setting treatment with a relaxation rate of 0.95 times in an inert gas at 180 ° C. was performed to obtain a deformed cross-section monofilament having a fineness of 500 dtex and a tensile strength of 900 MPa.
[0033]
Next, the above-mentioned monofilament monofilament was subjected to 60 turns / 10 cm in the Z direction using a ring twisting machine, and further subjected to a heat setting of 1.0 times in an inert gas at 180 ° C., and finished with Takemoto Yushi Co., Ltd. By applying TRN-190, a fishing line made of a twisted monofilament which was twisted in the longitudinal direction of the irregularly shaped monofilament and heat-set was obtained.
[0034]
[Examples 2 to 4]
A twisted monofilament that was heat-set under the same conditions as in Example 1 except that the fineness of the monofilament was changed to 250 dtex, 1500 dtex, and the cross-sectional shape was changed to a hexagonal shape under the same conditions. A fishing line consisting of
[Comparative Examples 1-6]
A fishing line made of a monofilament was obtained under the same conditions as in Example 1 except that the fishing line fineness, cross-sectional shape, presence / absence of heat set, and presence / absence of twist in the longitudinal direction were changed as shown in Table 1.
[0035]
Table 1 shows the results obtained by measuring the tensile strength and bending hardness of each fishing line and performing actual fishing evaluations -1 and 2.
[0036]
[Table 1]
Figure 0003909369
[0037]
As is clear from the results in Table 1, the fishing line of the present invention (Examples 1 to 4) is compared to the fishing line of Comparative Example 1 which is not subjected to twisting in the longitudinal direction and heat set (Comparative Example 1). In addition to being excellent in the smoothness of the yarn shown in Fig. 2, it is also excellent in the yarn wetting property shown in the actual fishing evaluation-2. As a fishing line that can be used comfortably throughout the day without any occurrence, the necessary and sufficient effects could be expressed.
[0038]
On the other hand, in the case of a fishing line (Comparative Example 2) that has a multi-leaf type cross section but is not twisted in the longitudinal direction, the smoothness indicated by the actual fishing evaluation-1 of the fishing line, and the thread indicated by the actual fishing evaluation-2. The warpability has not improved, and it has decreased with time, and when used for half a day, the long throwing property, the ease of pouring the device, etc. have decreased, and the yarn has become severely twisted or entangled Got caught at the tip of the heel and broke it.
[0039]
Furthermore, in the case of a fishing line that has been twisted in the longitudinal direction but not heat-set (Comparative Example 3), the thread has already been twisted, and the thread is entangled at the stage of winding the thread around the reel. Because it was closed, it could not be used for actual fishing evaluation.
[0040]
In the case of a fishing line (comparative example 4) in which the cross-sectional shape of the thread is a round cross-section, the twisting property shown in the actual fishing evaluation-2 is improved, but the slipping property shown in the actual fishing evaluation-1 is improved with a guide. The point of contact is not improved because it is a line contact, and as time passes, the long throwing ability and the ease of pouring of the device have deteriorated, and it is difficult to put the device on the point and the fishing result becomes extremely bad Oops.
[0041]
Further, in the case of a fishing line having a single yarn fineness that is too thin (Comparative Example 5), the absolute strength is insufficient, so that it is unsuitable for use as a road yarn for carp fishing, and a fishing line that has a single yarn fineness that is too thick. In the case of (Comparative Example 6), the rigidity of the yarn indicated by the bending hardness is increased, the yarn is naturally unwound from the spool, and the yarn becomes unsuitable for winding on a spinning reel. .
[0042]
【The invention's effect】
As described above, the fishing line of the present invention has a good sliding property and a low frictional resistance with the guide. Not only can the flying distance of the device be set even when the inner guide rod is used, Even when it is wound on a spinning reel, the yarn does not get twisted and exhibits an excellent effect of preventing line troubles.
