The fishing line according to the present invention is characterized in that a hot melt adhesive is used to integrate a plurality of filament yarns. The hot-melt adhesive is (a) solvent-free and has no pollution due to fire or solvent poisoning.
(B) Fast solidification time allows short-time adhesion,
(C) It has an advantage that a relatively wide range of adherends can be adhered.

The hot melt adhesive used in the present invention is an adhesive composed mainly of a thermoplastic polymer and having a solid content of 100%. After being melted by heat to reduce the viscosity and applied, it solidifies with cooling. , Refers to an adhesive that exhibits adhesive strength. In the present invention, the hot melt adhesive is not particularly limited as long as it is as described above, and a known hot melt adhesive may be used. Among them, the hot melt adhesive used in the present invention is preferably one that does not melt at about 100 ° C. or lower after curing. This is to prevent the hot melt adhesive from melting and solidifying in a state of being wound on the spool during transportation or storage of the fishing line. In addition, the melting point of the hot melt adhesive is preferably lower than the melting point of the filament yarn constituting the fishing line.

Examples of the hot melt adhesive used in the present invention include ethylene-based adhesives, depending on the type of base polymer.
Vinyl acetate copolymer (EVA) adhesive, polyethylene adhesive, polyolefin adhesive, thermoplastic rubber adhesive, ethylene-ethyl acrylate copolymer (EEA)
Examples of the adhesive include a system adhesive, a polyvinyl acetate copolymer system adhesive, and a polycarbonate (PC) system adhesive.

As the hot melt adhesive used in the present invention, a polyethylene adhesive or a polyolefin adhesive is preferably used. Polyethylene adhesives are preferable because they have excellent heat resistance, cold resistance, chemical resistance, and excellent adhesion to the adherend. The polyethylene adhesive is not particularly limited, and known ones may be used. For example, a saturated copolyester containing a copolymerization component such as isophthalic acid or a fatty acid dicarboxylic acid in a saturated polyester typified by polyethylene terephthalate or polybutylene terephthalate has low crystallinity and therefore has a relatively low melting point. Therefore, it is preferable from the viewpoint of ease of manufacturing such as coating. Above all, an adhesive having a molecular weight of about 10 to 30 × 10 ³ is preferable.

Such a polyethylene-based adhesive can be easily produced by a known method. For example, "Byron" (registered trademark) manufactured by Toyobo Co., Ltd., "Hardeck" (produced by Asahi Kasei Co., Ltd.) A commercial item such as "registered trademark" or "Chemit" (registered trademark) manufactured by Toray Industries, Inc. can be appropriately used. The polyester adhesive may have the form of an aqueous dispersion. As such a water-dispersible polyester adhesive, a known one such as "Vanarol" (registered trademark) manufactured by Toyobo Co., Ltd. may be used.

Polyolefin adhesives are preferable because they have excellent compatibility with materials to be adhered as compared with other base polymers. The polyolefin adhesive is not particularly limited, and known adhesives may be used. For example, amorphous polypropylene, a copolymer of polypropylene and ethylene,
Alternatively, an adhesive made of a copolymer of polypropylene and α-olefin can be used. More specifically, an atactic polypropylene resin, a random copolymer obtained by copolymerizing polypropylene and ethylene or 1-butene, and the like can be mentioned.

The polyolefin adhesive used in the present invention may be used in combination with other base polymer such as EVA, EEA or styrene thermoplastic resin. The polyolefin resin as the polyolefin adhesive may be a modified olefin resin grafted with an unsaturated carboxylic acid (for example, maleic acid or maleic anhydride) of the polyolefin resin or a derivative thereof.

Such a polyolefin-based adhesive can be easily produced by a known method, and for example, "Ube Tuck-APAO" manufactured by Ube Industries, "Sumitic" manufactured by Sumitomo Chemical Co., Ltd. or Commercially available products such as "Toughmer" manufactured by Mitsui Petrochemical Co., Ltd. can be appropriately used.

In the present invention, it is more preferable to use a reactive hot melt adhesive. When a fiber having excellent heat resistance such as wholly aromatic polyamide fiber, wholly aromatic polyester fiber or polyparaphenylene benzobisoxazole fiber is used as the constituent filament yarn of the fishing line according to the present invention, decomposition of such fiber Temperature is about 50
Since the temperature is as high as around 0 ° C., if a hot melt adhesive having a relatively high melting point is used, the hot melt adhesive will not melt during transportation or storage.

However, when the melting point of the filament yarn constituting the fishing line according to the present invention is relatively low, a hot melt adhesive having a melting point equal to or lower than the melting point of the constituent filament yarn must be used from the viewpoint of production. As a result, there is a high possibility that the hot melt adhesive will melt during transportation or storage of the fishing line. Therefore, if a reactive hot melt adhesive is used in such a case, the possibility that the hot melt adhesive will melt can be minimized. That is, in the reactive hot melt adhesive, a cross-linking reaction occurs after adhesion and heat resistance is improved. Specifically, even if the reactive hot melt adhesive is melted at a relatively low temperature and applied or impregnated into the constituent filament yarns, once bonded, the adhesive does not melt at a temperature of about 100 ° C. or lower. Therefore, if the reactive hot-melt adhesive is used as described above, it is possible to minimize the possibility that the hot-melt adhesive will melt during transportation or storage of the fishing line.

The reactive hot melt adhesive used in the present invention is not particularly limited, and known ones may be used. Among them, those that melt at a relatively low temperature, specifically about 60 to 130 ° C., preferably about 70 to 100 ° C. at the time of applying the adhesive are preferable. Specific examples of the reactive hot-melt adhesive include the following adhesives depending on the type of crosslinking reaction. For example, (a)
Ion cross-linking hot melt adhesive by carboxyl group in polymer and polyvalent metal ion; (b) Heat cross-linking hot melt adhesive that is cured by heating after adhesion; (c) Utilizing block copolymer or polyester having double bond ,
A hot-melt adhesive that causes a crosslinking reaction by irradiation with high-energy rays such as electron beams and ultraviolet rays; (d) by reacting with moisture (humidity) present in the air after melt coating or in the adherend Moisture-curing hot melt adhesive for crosslinking; or (e) Polymers having various functional groups and additives or polymers that react with functional groups present in the polymers are melted and mixed and coated immediately before coating. As a result, there are hot melt adhesives and the like that react two liquids to form a crosslinked structure.

As the reactive hot-melt adhesive used in the present invention, a heat-crosslinking hot-melt adhesive or a moisture-curing hot-melt adhesive is more preferable, and a moisture-curing hot-melt adhesive is particularly preferable. As the heat-crosslinking hot melt adhesive, specifically, (a) a terminal carboxyl group or amino group of polyester or copolyamide, or (b) an isocyanate group introduced at a molecular end or a side chain is used, such as caprolactam or phenol. A hot melt adhesive containing a blocked isocyanate blocked with a blocking agent can be mentioned.

The moisture-curable hot melt adhesive can be roughly classified into a hot melt adhesive having an alkoxy group introduced into the polymer and a hot melt adhesive having an isocyanate group introduced into the polymer. As a hot melt adhesive having an alkoxy group introduced into a polymer,
