DETAILED DESCRIPTION OF THE INVENTION

[0001]

TECHNICAL FIELD The present invention relates to a high-strength polyethylene.
It relates fishing line made of emissions textiles, in particular, the specific gravity high specific gravity component layer is coated on said surface about 1 greater than fishing line.

[0002]

2. Description of the Related Art Generally, a fishing line connecting a rod tip or a reel line winding to a hook is composed of a relatively thick road line and a harness from the line to the fishing line. Harris requires the following characteristics: (1) High tensile strength. (2) A strong knot with a string of yarn or a detour. (3) Have moderate waist. (4) It is small enough not to be found by fish etc. in the water. (5) There is little thread slack. And the like.
In addition to the above-mentioned properties, the properties required for the yarn are (6) high strength and low elongation. (7) Be resistant to friction. Etc.

Hitherto, monofilaments having different thicknesses using synthetic resin materials such as polyamide, polyester, and polyethylene have been used as fishing lines in accordance with fishing conditions such as target fish, fishing spots, weather, and fishing time zones. In particular, fishing lines made of polyamide have been mainly used from the viewpoint of strength.

However, due to the water absorption of polyamide resin, the tensile strength and knot strength tend to be low in water and in a wet state. Particularly, in the case of a fishing line of No. 0.2 or less, the tensile strength and knot strength are low. Was inadequate. On the other hand, the high-strength polyethylene monofilament has a tensile strength of 2 to 4 compared to fishing lines of other synthetic resin materials.
Since it is double and has low elongation, it is the most suitable material for fishing line, especially for harris with a small number.

[0005] Therefore, a single yarn, twisted yarn or braid of high-strength polyethylene monofilament, or a material obtained by winding a metal yarn around an aromatic polyamide fiber has been proposed.

[0006]

However, since the specific gravity of the polyethylene resin itself is smaller than that of other synthetic resins, a fishing line composed of only a combination of high-strength polyethylene monofilaments tends to float near the water surface, so that the fish There is a problem that the transmission of the fish signal when the fish catches the hook to the pole tip or the hand is delayed, and the fish hook moves unnaturally in the water and causes the fish to be alert.

Further, since the melting point of the polyethylene resin itself is lower than that of other synthetic resins, there is a problem that the abrasion resistance is inferior.

[0008] The present invention is a result of repeated experiments research to solve the problems described above, the high strength polyethylene mono filler ment
An object of the present invention is to provide a fishing line having a specific gravity of greater than 1 by coating the surface of a twisted or braided fiber with a high specific gravity component layer.

SUMMARY OF] According to the above construction, that Do poly ethylene fibers
A twisted yarn or braid surface, since the high density component layer are coated, it is possible to form the specific gravity of the fishing line to one or more. Therefore, the fishing line does not float near the surface of the water, and the operability of fishing is improved. In addition to improving the drainage of the fishing line and preventing line breakage, the surface becomes smooth, and the abrasion resistance and durability are improved, so that it does not easily shrink even when rubbed against obstacles such as rocks. .

Further, since the fibers constituting the braid are polyethylene fibers, a fishing line having sufficiently high tensile strength and low elongation can be obtained. Further, since the water absorption of the fishing line is small, the operability of fishing is improved. Further, since the layer to be coated on the surface is made of a resin in which powder of metal or metal oxide is dispersed, it is easy to form a high specific gravity. In addition, since the metal or metal oxide does not come into contact with the water or seawater at the fishing spot, it does not elute into the water, and the high specific gravity of the fishing line can be maintained forever,
There is no water pollution.

Further, the presence of metal or metal oxide of the fishing line of the present invention, by forming more than 10% by weight relative to the poly ethylene fiber, the water can be one or more the specific gravity of the entire fishing line Is eliminated.

Next, according to the configuration of the method of the present invention, the fishing line of the present invention can be efficiently and rationally manufactured.

/ In d above, it is 10% or less elongation. For the purpose of improving gloss, coloring, frictional resistance, etc.
Those obtained by copolymerizing 5% by weight or less of a monomer or polymer are also preferable. Further, since the polyethylene resin itself is smaller than the specific gravity of water, it is preferable to add an additive for increasing the specific gravity of the entire fishing line.

The polyethylene monofilament can be obtained by splitting a polyethylene multifilament. The use of split yarns is that (1) it is difficult in the manufacturing process to obtain a multifilament having a total denier of 100 denier or less by spinning and drawing. (2) A moderate kink or twisting habit remains due to fiber separation, and in the later assembling step or twisting step, friction and catch between single yarns are increased, and the integrity of the yarns can be increased. For reasons such as.

The polyethylene fibers can be assembled using a braiding machine generally called a braiding machine. This braiding machine mounts various kinds of yarns and metal yarns on a bobbin as a material, and crosses the bobbins by, for example, a figure-eight composition movement to form a braid, a woven braid, a braided braid, a twisted braid, a cut braid, and a crochet braid. It is a machine that makes bundles.

The pitch of the set is determined by the rotation ratio of the carrier and the wheel, and the gear ratio used for producing the fishing line of the present invention is preferably in the range of 1: 1.5 to 1: 5. When the fishing line of the present invention is manufactured, the rotation speed of the carrier and the wheel is 1 to 200 rpm, depending on the number of fibers of the braid, and the rotation speed of the wheel is 50 to 600.
A range of rpm is preferred.

Even if it rubs against an obstacle such as a rocky place, it is difficult to shrink, and the operability of fishing can be improved.

The coating process, the surface of the braid in combination <br/> polyethylene textiles, by coating the high specific gravity component layer such as a synthetic resin obtained by dispersing a powder of a metal or metal oxide, coating To form By this processing, it is possible to improve the drainage of the fishing line and prevent the line from scattering. Further, the surface becomes smooth, and the yarn wear resistance and durability can be improved.

A layer containing any one or a plurality of components such as semiconductor, glass, ceramics, and minerals can be applied to the fishing line of the present invention. Further, even a layer in which these components are mixed and dispersed in the above-described synthetic resin or the like can be applied to the fishing line of the present invention.

As a method for applying the coating resin, there are a dipping method, a spraying method, a printing method and the like, but it is preferable to apply the coating resin uniformly on the entire surface of the yarn. Resin curing methods include dry heat treatment, steaming, high frequency, radiation,
Although there are plasma treatments and the like, it is particularly preferable to cure at a low temperature and cure in a short time due to the properties of polyethylene fibers.

The thickness of the coating resin layer is preferably 0.5 μm to 500 μm depending on the purpose of use. Further, by dispersing a pigment such as a pigment or a dye in the coating resin, it is possible to color the entire thread, thereby improving fishing operability and improving fish collecting property. In particular, ultrahigh molecular weight polyethylene ethylene filament fibers used in the fishing line of the present invention, since the inability staining in the usual way, coloring by coating is preferred.
