Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a tungsten fishing line for fishing using a metal tungsten wire.

Conventionally, various thread-like materials have been used as fishing lines for fishing, such as threads, silk threads, hemp threads, nylon threads, stainless steel wires, and tungsten wires.

The properties required for these fishing lines are high tensile strength, high knot strength (for tying a fishing hook to the tip, etc.), flexibility, and no string curls (curls, kinks, etc.). There are various types of tubes that are resistant to repeated bending, and at present nylon thread is the most commonly used.

On the other hand, tungsten wire is often used as fishing line because it has extremely high tensile strength and high specific gravity (19,3), so it can omit weight when used as a hook. has been done.

However, such conventional tungsten wire generally does not have sufficient flexibility, making it difficult to tie a fishing hook.

Another problem was that the strength of the knot with the fishing hook was weak, and the thread was prone to twisting, curling, and other fraying.

This invention was made in view of these circumstances, and aims to provide a fishing line that has far greater tensile strength than the conventionally used nylon fishing line, yet is more flexible than the tungsten wire mentioned above. .

The details will be explained below.

The tungsten fishing line according to the present invention is characterized by being made by interweaving a plurality of tungsten wires.

That is, in this tungsten fishing line, a plurality of tungsten single wires are interwoven with each other as in a normal braided cord to form a thread-like material.

In this interwoven structure, each tungsten wire can deform relatively freely in response to external forces, so the resulting filament is extremely flexible as a whole.

There are usually two types of braids: round and flat, but in this case round is more practical.

The diameter of the resulting tungsten fishing line (thread-like material formed by interweaving) is influenced by the diameter and braiding method of the original tungsten wire (hereinafter referred to as the original wire).

Since it is generally preferable for fishing line to have a thin diameter and strong strength, it is preferable to select a raw wire having a diameter of 10 microns (μm) to 100 microns.

Raw wires thinner than this are difficult to handle and have problems in terms of strength.

Further, a raw wire thicker than this will have high rigidity, which will cause problems in the flexibility of the resulting fishing line, and there is also a risk that the diameter of the fishing line itself will become too thick.

It is appropriate that the number of primitive wires used is about 8 to 16.

When the amount is less than this, the difference between the plurality of raw wires and the twisted wire produced by twisting them together becomes smaller.

In addition, the number of raw wires is increased (for example, to 40) to create double or triple knitted layers (that is, a cylindrical knitted layer is formed on the outside of the cylindrical knitted layer). There is also a method, which can increase the strength of the resulting fishing line without significantly reducing its pliability, but is uneconomical unless specifically required.

Note that the original wire may be a black line or a white line (by electrolytic polishing or the like).

As explained above, since this tungsten fishing line is made by knitting raw wires together, it is far superior in flexibility to tungsten wire that has the same tensile strength.

Additionally, the tensile strength of this tungsten fishing line is much greater than that of nylon fishing line of the same diameter.

In other words, this tungsten fishing line has far greater tensile strength than the conventionally used nylon fishing line, yet is more flexible than the conventional fishing line made of tungsten wire, making it extremely practical. .

Furthermore, since the weight per unit length is overwhelmingly greater than that of nylon fishing line of the same diameter, it is difficult to be washed away by complicated currents, and depending on the usage conditions, it is possible to omit the weight (usually a lead lump). .

In addition to these major features, when tying a fishing hook to the tip, the knot is stronger than with conventional fishing line made of tungsten wire, and the line tends to be less prone to kinks, curls, and other distortions.

Next, in order to further improve the performance of the tungsten fishing line made of such a braided wire, it is preferable to apply a flexible plastic coating to the outer surface of the tungsten fishing line.

Flexible nylon or the like is suitable as the plastic for the covering.

The thickness of the coating varies from several microns to several tens of microns depending on the outer diameter of the fishing line.
Preferably, it is in microns.

When applying the plastic coating, the plastic of the coating material passes through the stitches and enters the inside of the tubular knit layer, forming a plastic core, but the resulting fishing line (in this case plastic does not significantly affect the flexibility of tungsten fishing line (coated with tungsten fishing line).

In this way, by applying a flexible plastic coating to the outer surface of a tungsten fishing line made of a plurality of tungsten wires, corrosion resistance is improved and slippage is improved, resulting in a fishing line that is even better in practical terms.

The straightness of the fishing line is often improved by applying such a coating.

Example 1 Tungsten braided wires of various outer diameters were made using a commercially available braiding machine (string making machine), and their properties were compared with those of conventional nylon fishing line. The results are shown in Table 1.

The braiding machine used is the round braiding machine (AI) manufactured by Kokubu Tekko Co., Ltd.

As is clear from this figure, the tensile strength of tungsten braided wire is much greater than that of conventional nylon fishing line.

In addition, these tungsten braided wires can be used as tungsten solid wires with similar tensile strength or tungsten stranded wires with the same diameter (16
It was much more pliable than real twisted yarn, and could be easily tied to a fishing hook.
