Field of the Invention The present invention relates to a longline trunk line and a fishing line used for fishing large fish such as tuna, and more particularly to a longline trunk line which is particularly excellent in catchability and fishing efficiency. And fishing line.

るものが知られている。2. Description of the Related Art As a long-line trunk rope conventionally used for fishing large fish such as tuna, for example, a bundle of a large number of multifilament yarns having a perfect circular cross section made of polyester or nylon is used. It is known that three strands are twisted by using this.

題があった。[0003] However, the trunk line for long lines made by triple twisting has a high flexibility, but since the yarn is a multifilament, the water retention rate is very high, and the peculiar habit of the twisted yarn, that is, the yarn peculiarity Has a kink easily during work,
There was a problem that the operability was poor because the branch rope was entangled with the trunk rope and the trunk rope for long line could not be put in and rolled up smoothly.

コストの大幅な上昇につながると言う問題があった。In order to solve this problem, a trunk line for a long line has recently been proposed, which is formed by braiding eight to twelve nylon monofilament yarns made of synthetic resin having a perfect circular cross section. The trunk line for long lines made by using the monofilament yarn is harder than the case where the multifilament yarn is used, the workability is very poor, and the moisture absorption rate which is a property of nylon is high. However, due to poor weather resistance, the period during which it can be used for operation is shortened, which causes a significant increase in operating cost.

紐すると、作業時の水切れが良いが、ナイロン樹脂は他
の素材に比較して高伸度であるため高速での巻き上げ作
業時に伸びが発生し、巻き上げ時間がかかり、そのため
に種々のトラブルが発生しやすい。Further, since large fish such as tuna migrate in a wide range, in order to improve the fishing result, they are continuously thrown in a range of several tens to hundreds of tens of kilometers in one operation. If you use a perfect circular monofilament yarn made of nylon for the long line installed over this long distance, the water will be drained well at the time of work, but nylon resin has a higher elongation than other materials. Therefore, stretching occurs during high-speed winding work, and winding time is long, which causes various problems.

でしまい、収まりが悪く、所謂バックラッシュ現象が起
こる欠点がある。On the other hand, when a monofilament yarn made of polyester and having a perfect circular cross section is used, the elongation generated due to the properties of the resin is small. The trunk line for long line of this becomes very hard. Therefore, there is a drawback in that the tightening and loosening of the string thread is poor and the string thread is not well set and a so-called backlash phenomenon occurs.

あった。For this reason, when a polyester yarn is used, a trunk line for a long line has been used in which multifilament yarns having a narrow warp are collected and twisted into a triple twist. However, when the multifilament yarn is used, a large amount of water is retained between the yarns, and as a result, so-called drainage is extremely bad, the long rope itself becomes heavy, and the workability on board is deteriorated. Further, in general, the tuna longline fishery is carried out over a wide range from tens of kilometers to hundreds of tens of kilometers as described above, and as a result, the longline is carried out mechanically. The fishing speed is quite high, the trunk rope is worn by various rollers of the hoisting machine, the strength is significantly reduced due to deformation of the trunk rope and breakage of the multifilament yarn, and the trunk rope must be replaced early. In addition, there was a problem that the burden was large economically.

あった。Further, in addition to trunk ropes for long lines, there are known fishing lines made of 8 to 12 monofilament yarns made of synthetic resin having a perfect circular cross section in order to increase strength. However, also in this case, there was a problem that the workability was very poor as in the case of the trunk line for long lines and the workability was extremely poor.

た。The present invention will be described in detail below. The material of the monofilament yarn having a flat cross section in the above-mentioned trunk line for fishing and fishing line is considered to be synthetic resin such as polyester, nylon and polyolefin. Among them, polyester is preferable. Since it has extremely good weather resistance compared to other resins,
Polyester was used for the trunk line and the fishing line for the long line of the present invention.

強力を有する延縄用幹縄を得た。Various lengths can be considered as longline trunks, but when the longline trunks are composed only of monofilament yarns having a flat cross section made of polyester,
The fineness of the monofilament is preferably 2700 to 18500 denier. Then, the total denier of each yarn forming the trunk line is 32,000 to 120,000.
Was adjusted so that the outer diameter was about 2.0 to 4.5 mm, and a longline trunk rope having a tensile strength of about 160 to 600 kg was obtained.

る。FIG. 1 shows a polyester monofilament having a flat cross section which is used for a trunk line as described above. The long axis of the monofilament 1 having a flat cross section is a and the length of the short axis is a / b is 1.2-4.
Must be in the range of 0. When a / b is less than 1.2, the monofilament becomes close to a perfect circle and the rigidity becomes strong, and each monofilament yarn constituting the trunk line repels to cause a backlash phenomenon.
In addition, there is a problem in that workability is deteriorated because the cord-made long-line trunk rope becomes too hard. Further, when a / b exceeds 4.0, there is a problem that the flexibility is remarkably increased, and the product is in a state of being braided with only the multifilament, which is likely to be entangled, has poor thread separation, and has poor drainage.

縄用幹縄が得られる。A particularly preferred ratio of the major axis / minor axis of the trunk line according to the present invention is in the range of 1.5 to 2.5. If a monofilament made of polyester in this range is used, the problems described above can be solved, and an ideal trunk line for long lines can be obtained.

めに、耐摩耗性が著しく向上する。Since the polyester monofilament having a flat cross section is used for braiding, the major axes overlap each other. Therefore, the surface of the main rope after the braiding is finished is remarkably different from the case where a monofilament having a perfect circular cross section is used for braiding. Less unevenness,
When braided using the same denier monofilament, the thickness of the trunk rope after the braiding can be reduced. Furthermore, since the surface has few irregularities and is very smooth, the wear resistance is remarkably improved.

In the trunk line for longline shown in Fig. 5, fibers having a specific gravity of 1.5 or more or metal powders are attached by resin to form fibers having a specific gravity of 1.5 or more as the core yarn 3, and the cross section around the core yarn 3 is flat.
