Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a blackish-brown fishing line with a height of m that has excellent sedimentation properties.

More specifically, the present invention relates to a fishing line suitable for fishing for sweetfish and carp and deep sea fishing.

For regular fishing lines for sweetfish and flathead carp, monofilament type monofilament resins made of polyamide resin, especially nylon 6, among synthetic resins, are commonly used.
It is commercially available in colors such as red and yellow.

Nylon 6 monofilament is highly flexible, has high strength, and has moderate elongation, and has the most balanced basic performance required for general fishing lines such as fishing lines and Harris. However, since nylon 6 has a specific gravity of 1.14, which is relatively close to that of water, there is a problem in that it sinks slowly in water.

For example, when using nylon 6 monofilament 1- as a fishing line for carp fishing, curvature occurs between the tip of the fishing rod and the float, and it is difficult to get a slight hit. If the thread is light and curls as described above, the crack will become large, and as soon as the thread breaks, a large impact will be applied and the thread will break, resulting in what is called a crack. Zunawara fishing line is generally quite strong as long as it is pulled in a straight line, but if it has even a slight curvature and is concentrated in a local area where a large amount of force is applied, it can easily break.

In addition, scoring points is extremely important in fishing, but if the line is too light, the float will be blown away by the river waves and you will miss the point.On the other hand, if the line is too heavy, the line will sink and you will get points accordingly. It will be moved towards the front.

Furthermore, as the Harris part of the fishing line, the thinnest fishing line is used in order to improve the bite and increase fishing results, but in this case too, if the Harris is light, it is difficult to get points, and it is difficult to knead. There is a problem with the food being scattered.

Conventional methods to address the drawbacks of fishing lines made of nylon monofilament include treating the surface of the monofilament with a surface treatment agent that has good sedimentation properties, such as a surfactant or oil. This method still has drawbacks such as the effect of improving sedimentation properties being insufficient, and the surface treatment agent falling off while the fishing line is in use, resulting in no longer being effective.

On the other hand, deep-sea fishing line that can be used at depths of several hundred is operated using a high-speed electric reel, so in this case as well, high specific gravity and fast settling speed are required. Currently, multi-twist type fishing line made of polyethylene terephthalate is used as the main material for this purpose, but higher specific gravity is desired for this purpose as well.

Therefore, the inventors of the present invention investigated the purpose of obtaining a fishing line with an appropriate specific gravity that sinks quickly, and found that if the performance is covered by weight, the original characteristics such as the strength and flexibility of the fishing line itself will be reduced. The present invention was achieved by discovering the best additive for J-rudame, which improves its sedimentation properties.

In other words, in the present invention, 1 to 15% of ferrite is added to the synthetic resin.
% by weight, and melt-spun it to provide a fishing line.

Synthetic resins used in the present invention include polyamides such as nylon 6, nylon 66, and nylon 12, polynisdels such as polyethylene terephthalate and polybutylene terephthalate, polyolefins such as poly:1-burene, and polypropylene, and polyvinyl chloride and polyfluoride. Examples include melt spinnable thermoplastic resins such as polyvinyl halides such as vinylidene.

In addition, the ferrite used in the present invention is IVI O・F
e20s (M=Mn, Zn, Co, Cu, etc.)
-High specific gravity iron oxide fine particles consisting of a composition of (-valent metal ions), have good cross-talk with synthetic resins, are easy to adjust the amount added, and have no adverse effect on yarn-spinning properties. Gives monofilament excellent settling properties and a dark brown color.

The addition of ferrite to synthetic resin is 1 to 15% by weight.
In particular, 2 to 10% by weight is appropriate; less than 1% by weight will have little effect on improving sedimentation, and more than 15% by weight,
This is not preferred because the spinnability decreases.

The fishing line of the present invention is produced by adding and mixing the required amount of ferrite to a synthetic resin, and spinning this using a normal melt extrusion spinning machine.
It can be further obtained by stretching and heat-setting if necessary.

The fishing line of the present invention includes not only one formed from high-denier monofilament itself, but also a so-called mono-mulch form in which a plurality of monofilaments are twisted together.

Thus, the fishing line of the present invention has a specific gravity increased by 2 to 3%, has excellent settling properties, has a good blackish-brown color tone, and has reduced stickiness, and is suitable for general road fishing lines, especially sweetfish and spatula. It is useful as a line for carp fishing, as well as a line for deep-sea fishing.

The present invention will be further explained by giving nine examples below.

Example 1 To a nylon 6 M1021T chip manufactured by Toshi ■, 2% binder oil was added using 8% ferrite fine particles as a dispersant.
% by weight, melt-spun using an ordinary extruder, inclusion, stretching, and heat treatment to obtain a diameter of 0.16 mm.
5mm, dark brown monofilament with a ratio i of 1.22 <A)
1. On the other hand, for comparison, spinning was carried out in the same manner without adding ferrite to obtain a yarn with a diameter of 0.165+++tll and a ratio of ff1.
A monofilament (B) of 1.14 was obtained.

The results of a practical test in which these monofilaments (A) and (B) were used as line and wire for flathead carp fishing are shown below.

[Monofilament (A)] Road line ~ The thread is stretched almost straight from the tip of the fishing rod without any walnut parts, ensuring a stable position without being blown off the point by the calm wind, and making subtle adjustments. I got the hit.

The harris sinked quickly, hit the point accurately, and there were no barracks for bait (but it was stable).

[Monofilament (B) Kodo line ~ A lot of walnuts occur between the tip of the fishing rod and the float,
The points were blown away by the wind and became unstable.

Therefore, I was unable to get a slight hit.

Harisuru sinks slowly, and I can't catch the point (it's unsteady, and the kneaded bait is also loose).

Example 2 10% by weight of ferrite fine particles were mixed with 2% by weight of binder oil as a dispersant into a polyethylene terephthalate T-301M chip made by Toshi ■, melt-spun with a normal extruder, and then stretched and heat treated. The diameter is 0.130mm.

A brown monofilament with a specific gravity of 1.49 was obtained.

Next, eight of these monofilaments were twisted to obtain a monomulti-type twisted yarn (C) 1.

On the other hand, for comparison, spinning was carried out in the same manner without adding ferrite to obtain a monofilament with a diameter of ○, I of 30 mm, and a specific gravity of 1.37. Eight of these were twisted to form a monomulti-type twisted yarn (D > obtained.

These twisted yarns (C) and (D) were placed in water at a depth of approximately 400 m.
The results of a practical test using this as a deep-sea fishing line are shown below.

L-ply twisted yarn (C)] The sinking speed was fast, it caught the point reliably, and was less likely to be washed away by waves or currents.

[The plied yarn (D) had a slow settling speed and was carried away by wind waves and currents, making it difficult to obtain points.
