Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

TECHNICAL FIELD The present invention relates to a monofilament comprising a two-component polymer colored in different colors,
The present invention relates to a fishing line which exhibits a green color with uneven spots, and is suitable for road lines and harris.

[0002]

2. Description of the Related Art Conventionally, monofilaments of nylon or polyester have been used for fishing lines. A commonly used colorless and transparent monofilament is used, but it does not tell in which direction it flew when thrown and where it entered the water. Therefore, fishing lines colored in various colors have been proposed and used.

[0003] For example, Japanese Patent Publication No. 45-15864 discloses 2
There has been proposed a tex comprising a composite monofilament in which a plurality of different colored resins are bonded in a side-by-side type. The publication describes, for example, a side-by-side yarn composed of a white resin and a blue resin, but since this yarn is simply a two-color polymer bonded to a side-by-side type, the appearance of this fishing line is as follows.
It was a light blue color.

[0004] As described above, other colored fishing lines have been proposed, but all of them are simply composed of one kind of colored polymer or two or more kinds of different colored polymers bonded together. In addition, even when two or more kinds of polymers are used, the color appearance is uniform because the relationship and ratio of colors to be combined are not considered.

[0005] When such a fishing line is used for a road line, it is effective for human beings to discriminate, but the difference from the surrounding scenery is too clear. There was a problem of not going up.

[0006]

SUMMARY OF THE INVENTION The present invention solves the above-mentioned problems, and is suitable as a yarn and a harris, and is colored to the extent that humans can distinguish it. An object of the present invention is to provide a fishing line that is well-melted with the surrounding scenery, does not have a cautionary effect on the fish, and has a high fishing result.

[0007]

Means for Solving the Problems The present inventor has studied to solve such problems, and as a result, has arrived at the present invention. That is, the present invention relates to a thermoplastic polymer A containing 0.1% by weight or more of carbon black, 0.1% by weight or more of a component incompatible with the polymer, and 0.0% of a yellow colorant.
A monofilament obtained by laminating a thermoplastic polymer B containing at least 15% by weight and having an area ratio of the polymer A and the polymer B in the cross section of 40:60 to
The ratio is 10:90, and the gist is a fishing line having a special color, wherein the polymer A occupies 45% or less of the fiber circumference.

[0008]

BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, the present invention will be described in detail.
The fishing line of the present invention is a monofilament formed by laminating thermoplastic polymer A and polymer B. The thermoplastic polymer used is nylon 6, nylon 6
6, polyamides such as nylon 610, polyesters such as polyethylene terephthalate and polybutylene terephthalate, polyvinyl chloride, polyvinylidene chloride, polystyrene, polypropylene, polyvinylidene fluoride and the like are used. Above all, a polyamide having sufficient strength, elongation, flexibility and the like as a fishing line is preferable, and these polymers may be two or more copolymers.

The polymer A and the polymer B may be different types, but it is preferable to use the same type of polymer in order to improve the bonding property of the bonding surfaces.

[0010] In these polymers, the third component is mixed or copolymerized, or a matting agent, a stabilizer,
It may be one containing an antistatic agent or the like.

The fishing line of the present invention has a polymer A which is colored dark (mainly black) and a polymer B which is colored yellow, and has a green color as a whole. Because of this, it is a color that easily blends into the surrounding landscape.

In the polymer A, the thermoplastic polymer contains carbon black in an amount of 0.1% by weight or more. When the carbon black is less than 0.1% by weight,
The monofilament after being bonded to the polymer B is not colored dark and does not turn green. The polymer A contains 0.1% by weight or more of carbon black in order to make it darker, but if the amount of carbon black is more than that, other colorants are contained. For example, the color may be blue or brown by adding another coloring agent.

The upper limit of the content of carbon black is not particularly limited, but is 5.0 in order not to lower the characteristics (strength and elongation) of the fishing line.
% By weight or less, and when adding other coloring agents, it is preferable not to exceed this amount.

The polymer B contains a component incompatible with the thermoplastic polymer B as described above and a yellow colorant. The component that is incompatible with the polymer B is added so as to be green as a whole when bonded to the polymer A. In other words, the dark color (mainly black) and the yellow color have a stronger hue in the black color, and the yellow color with good light transmittance does not show green as a whole when they are bonded together. Therefore, in the present invention, it is necessary to add an incompatible component which forms an interface with the thermoplastic polymer in the polymer B and diffusely reflects light.

Therefore, the component incompatible with the polymer is a component which forms an interface with the polymer and diffuses light, and among those which do not lower the characteristics as a fishing line, polyethylene, titanium oxide, silicon, etc. It is preferable to use These may be used in combination, and it is necessary that the thermoplastic polymer B be contained in a total amount of 0.1% by weight or more.

If the content of the incompatible component is less than 0.1% by weight, the above-mentioned interface is formed, there is no effect of irregularly reflecting light, and the monofilament bonded with two kinds of polymers does not turn green. . The upper limit of the content of the incompatible component is
Although not particularly limited, it is preferable to be 5.0% by weight or less so as not to lower the characteristics (strength and elongation) as a fishing line.

Furthermore, the thermoplastic polymer B contains 0.015% by weight or more of a yellow colorant. When the content of the yellow colorant is less than 0.015% by weight, polymer A
When they are bonded together, they no longer show green. The upper limit of the content of the yellow colorant is not particularly limited, but is preferably 5.0% by weight or less so as not to lower the properties (strength and elongation) of the yarn.

As the yellow colorant, pigments and dyes can be used, and specific examples thereof include metal-containing azo yellow, heterocyclic yellow, anthraquinone yellow, and quinophthalone yellow. Can be

Next, the shape of the fishing line of the present invention will be described with reference to the drawings. 1 to 3 are sectional views showing an embodiment of the fishing line of the present invention. In the fishing line of the present invention, the polymer A
In the cross section, the area ratio between the polymer A and the polymer B is 40:60 to 10:90, and the polymer A occupies 45% or less of the fiber circumference.

FIG. 1 shows that the polymer A and the polymer B are bonded together, the area ratio of A: B is 25:75, and the polymer A occupies 30% of the fiber circumference, and FIG. The area ratio of A: B is 30:70 and the polymer A occupies 30% of the fiber circumference. FIG. 3 shows that the area ratio of A: B is 35:65 and the polymer A occupies 40% of the fiber circumference. Occupy.

In the present invention, the polymer A and the polymer B are stuck together at the above-mentioned area ratio, and the polymer A is 45% or less of the fiber circumference, so that the whole is uniformly green. Instead, it becomes green with spots,
It has a color tone that blends into the surrounding landscape.

Accordingly, when the area ratio of the polymer A is larger than the above range, the black color of the polymer A is superior, and the polymer A does not become green as a whole, or becomes a uniform green color as a whole. On the other hand, when the area ratio of the polymer B is larger than the above range, the yellow color of the polymer B is superior and does not become green, but becomes uniform yellow as a whole.

On the other hand, when the polymer A exceeds 45% of the circumference of the fiber, the color becomes blackish and becomes uniform green as a whole, and becomes closer to black as the proportion of the polymer A increases.

In the fishing line of the present invention, the bonding shape of the polymer A and the polymer B is not particularly limited as long as the above conditions are satisfied. As shown in FIG. The mating surface may be curved and may be eccentric to one side without including the center portion, or the polymer A may be bonded to the polymer B in a fan shape as shown in FIG. Further, as shown in FIG. 3, a polymer A and a polymer B may be bonded in a side-by-side type.

Next, a method for producing a fishing line according to the present invention will be described. Polymer A contains carbon black,
The polymer B contains an incompatible component and a yellow colorant, is melted by separate extruders, and is subjected to composite spinning using a composite spinneret. Then, the spun monofilament is guided into a water bath, cooled, taken up at a rate of 8 to 32 m / min, and subsequently stretched 3 to 7 times and wound up. The fineness and physical properties of the fishing line of the present invention are not particularly limited as long as they can be used as a fishing line.
75-4000d, linear strength 8.0-10.5g
/ D and elongation of 20 to 40% are preferred.

As described above, according to the fishing line of the present invention, since it has an appearance of being colored in green with uneven spots, it can be recognized by the human eyes that it can be discriminated where it is thrown. Because of the presence of a spot and a feeling of spots, it blends well with the surrounding scenery, has a so-called camouflage effect, and when used as a harris, the fish does not have a vigilance and the fishing results increase.

[Table 1]

As is clear from Table 1, the monofilaments of Examples 1 to 4 have a green appearance with uneven spots, are excellent in discrimination, and have a good sense of blending into the scenery. The fish were not vigilant, and the catch was good. On the other hand, in the monofilaments of Comparative Examples 1 and 2, the ratio of the polymer A and the polymer B was not appropriate, and further, in the monofilament of Comparative Example 1, the circumference of the polymer A was too large.
In Comparative Example 2, a monofilament of a single color of yellow was obtained, which was inferior in the sense of blending into the scenery. In the monofilament of Comparative Example 3, the polymer B was a colorless and transparent polymer, and in the monofilament of Comparative Example 4, the polymer A was a colorless and transparent polymer. ,
It was inferior to the scenery. Comparative Example 5
The monofilament of Comparative Example 6 did not contain carbon black because the monofilament of Comparative Example 6 did not contain carbon black because the combination of colors of the polymer A and the polymer B was not appropriate. Since the amount of the yellow colorant to be contained was too small, these monofilaments did not become mottled green and were inferior to the scenery.
