Description

[Technical Field]

[0001] The present invention relates to a fishing line protection yarn. [Background technology]

[0002] For example, in sea lure fishing, the lure (artificial bait) is not tied directly to the main line (fishing line), but rather a separate, strong fishing line called a leader is tied to the end of the main line, and the lure is tied to the end of that leader.

[0003] Instead of traditional fishing using live bait, lure fishing uses lures, making it a sporty and easily enjoyable form of fishing that is enjoyed by a wide range of people, regardless of age or gender. In particular, ajing, which involves using lures to catch horse mackerel (horse mackerel), which are widespread throughout Japan, and mebaring, which involves using lures to catch rockfish (mebaru), have become popular in recent years as lure fishing that can be enjoyed in a short amount of time. Horse mackerel are migratory fish, and rockfish are also found widely along the coast of Japan. Both are small but have a strong pull, so they are popular because they allow you to experience the thrill of lure fishing as a sport, as well as the enjoyment of tasting the horse mackerel or rockfish you catch.

[0004] The rigs used for lure fishing, such as horse mackerel fishing, consist of a jig head attached to the end of the fishing line reeled out from the rod, with a worm or other artificial bait attached to the jig head. Various rigs are used, with a sinker (weight) attached a certain distance from the jig head. A jig head is a type of fishing rig with a hook integrated with a weight of various weights. It is generally used with worms (artificial bait) and can be used to target a wide variety of fish species. The size of the weight and hook can be adjusted depending on the target fish. Jig heads have an integrated weight and worm that directly impart movement to the attached hook, making the worm move lively. By changing the weight, the weight of the weight can be changed depending on the target fish species and fishing spot, such as dropping it to the surface or deeper. Furthermore, when fishing with a jig head, in addition to the shape and weight of the weight, the shape and size of the hook can be changed to suit the fish being caught.

[0005] Incidentally, fish live in different layers and swim in different layers depending on the species, current, weather, season, etc. In order to catch fish, the key to success in lure fishing is to cast the rig into the target sea area, let it slowly sink to the habitat or swimming layer of the target fish, and for the angler to sense the movement of the jig head in order to operate the jig head appropriately according to the situation in order to attract the target fish.

[0006] For example, Fig. 1 shows a schematic diagram of one embodiment of a lure fishing tackle 1. In Fig. 1, 3 is a jig head with a weight member 3b attached to the end of a hook 3a. 4 is a worm as a soft lure attached to the hook 3a.

[0007] A leader 5 connected to a jig head 3 is connected to the tip of a main line (main line) 6, which serves as a fishing line from the rod, and a second stopper 8 is attached to the leader 5 at a certain distance from a first stopper 7 in the direction of the jig head 3. The leader 5 has a larger diameter than the main line (main line) 6 to prevent it from breaking due to friction with rocks or fish in the sea.

[0008] 2 is a sinker (weight), which is located a certain distance from the jig head 3 and has a mounting fixture 9 such as a swivel 9 slidably connected to the leader 5 between the first stopper 7 and the second stopper 8. By engaging the sinker 2 with the mounting fixture 9, the sinker 2 can slide freely within a certain section L of the leader 5.

[0009] In lure fishing, the lure fishing tackle 1 must be able to be freely cast into the target sea area. To achieve this, the weight of the fishing sinker is selected to be weight that will not be swept away by currents, will allow for rapid sinking, and is also optimally suited for casting. As a result, casting distance can be increased, dramatically expanding the fishing range from the angler's position. However, the main line 6 is easily worn because it rubs against the guide portion of the fishing rod with each cast. Figure 2(A) is a side view of the tip 10A of one embodiment of a lure fishing rod 10, and Figure 2(B) is an enlarged perspective view of the guide portion 12 of the fishing rod. The guide portion 12 has base ends 12B and 12C of the annular portion 12A fastened to the rod tip 10A by fastening thread 13. The guide portion 11 differs from the guide portion 12 in that the base end of the annular portion is located on only one side of the annular portion.

[0010] In order to prevent wear and tear on the main line during casting, until now, the main line has been protected by piercing it through the center of a protective thread made by round weaving using a needle, and covering part of the main line with the protective thread.

[0011] That is, up until now, the main line 16 shown in Figure 3 has been passed through the end opening 15a of the needle 15 shown in Figure 4 to create the state shown in Figure 5, and then, as shown in Figure 6, the tip of the needle 15 is pierced through the center of a part a little away from the end of the protective thread 14 that has been braided by round punching as shown in Figure 3, and then the needle 15 is pulled out from one end of the protective thread 14 and the needle 15 is continued to be pulled, so that the main line 16 penetrates the hollow part of the protective thread 14 as shown in Figure 7, and part of the main line 16 is covered with the protective thread 14, thereby protecting the main line 16.

[0012] However, the task of inserting the needle 15 longitudinally through the protective yarn 14 is extremely time-consuming, and the needle 15 may get caught on the protective yarn 14 during the inserting process, damaging the protective yarn 14. Summary of the Invention [Problem to be solved by the invention]

[0013] The present invention has been made in consideration of the above-mentioned problems, and its object is to provide a main yarn protection yarn that can cover a part of the main yarn to protect the main yarn, and that does not itself become damaged. [Means for solving the problem]

[0014] In order to achieve the above object, the first invention is a main yarn protection yarn comprising a core yarn and a sheath yarn, the core yarn being a braided yarn or twisted yarn made of multiple filaments, and the sheath yarn being braided around the core yarn with multiple filaments.

[0015] In a second aspect of the present invention, the filament of the core yarn is a monofilament, in the first aspect of the present invention.

[0016] In a third aspect of the present invention, in the first aspect of the present invention, the filament of the core yarn is a multifilament.

[0017] A fourth invention is the fiber optic cable according to any one of the first to third inventions, wherein the filament of the sheath yarn is an ultra-high molecular weight polyethylene fiber.

[0018] A fifth invention is the fiber according to any one of the first to third inventions, wherein the filament of the sheath yarn is a polyarylate fiber.

[0019] A sixth invention is the fiber optic cable according to any one of the first to third inventions, wherein the filaments of the sheath yarn are aramid fibers.

[0020] A seventh invention is the fiber according to any one of the first to third inventions, wherein the filament of the sheath yarn is a polyparaphenylene benzobisoxazole fiber.

[0021] An eighth aspect of the present invention is the braiding machine according to any one of the first to seventh aspects, wherein the sheath yarn is braided using a round braiding machine. [Effects of the Invention]

[0022] When the main yarn is passed through the sheath yarn from a direction perpendicular to the longitudinal direction of the main yarn protection yarn of the present invention so as to reach the core yarn, the main yarn and the core yarn made of a braiding yarn or a twisted yarn become entangled, so that by pulling out the core yarn from one end of the yarn, the main yarn can be smoothly guided to the center of the yarn, using the core yarn as a guide, and by continuing to pull the core yarn, the main yarn can be covered with the yarn without damaging it, thereby protecting the main yarn, and as a result, an improvement in casting distance can be expected.

[0024] Although the following describes embodiments of the present invention, it goes without saying that various changes and modifications can be made without departing from the technical scope of the present invention.

[0025] The braiding yarn of the present invention is produced by using filaments as braiding constituent yarns and combining and braiding at least three or more braiding constituent yarns, for example, four, eight, twelve, sixteen, etc., in a state in which the relative positions and relative postures of the braiding constituent yarns can be changed.

[0026] The braiding method is not particularly limited, but is usually performed using a braiding machine (braiding machine). In this case, the braid may be made using only the constituent threads, or a core thread may be placed in the center and braided around it with the constituent threads. The core thread may be a monofilament, a multifilament, or an inorganic fiber such as glass fiber or metal fiber, either alone or in combination.

[0027] When actually fishing with a fishing line having a fishing line protected by the fishing line protection thread of the present invention, a specific position in the longitudinal direction may rub repeatedly against rock corners, etc. On the other hand, the above-mentioned cord-making yarns usually have the disadvantage of being easily cut when rubbing against an object in a direction perpendicular to the longitudinal direction. For this reason, the more inclined the cord-making yarns are with respect to the longitudinal direction of the cord-making yarn, the less likely the cord-making yarn will be cut when rubbing against another object, and the abrasion resistance of the cord-making yarn can be improved, which is preferable. Therefore, the pitch number at which the above-mentioned cord-making yarns are raised varies depending on the thickness of the cord-making yarns and is not limited to a specific value, but is preferably 5 to 50 yarns per inch, and more preferably 14 to 50 yarns per inch.

[0028] The above-mentioned braiding yarn can also be subjected to a heat drawing treatment. However, in this case, the heating temperature and heating time are set so that the heating during drawing does not cause the individual braiding yarns to fuse together so that they cannot be displaced. Furthermore, drawing the braiding yarn has the advantage of improving the strength of the braiding yarn. However, when the braiding yarn is drawn, the braiding yarn is displaced in the length direction of the braiding yarn. For this reason, a braiding yarn that has not been drawn after braiding is preferred because it can maintain a large inclination angle of the braiding yarn with respect to the length direction of the braiding yarn and improve the abrasion resistance of the braiding yarn.

[0029] The braiding yarns may be coated with a synthetic resin in a state in which each braiding yarn is allowed to change position or posture. Examples of such coating resins include polyolefin resins and modified products thereof, polyamide resins, acrylic resins and modified copolymers thereof, polyurethane resins, polystyrene resins, vinyl acetate resins, polyvinyl chloride resins, and epoxy resins. These coating resins may also contain metal particles or the like.

[0030] The filaments constituting the multifilament are not limited to any particular material, and examples include filaments made of thermoplastic resins such as polyamide resins, polyester resins, fluorine-containing resins, and polyolefin resins. Among these filaments, it is preferable to use high-strength filaments with a tensile strength of about 20 g / dtex or more, preferably about 25 to 50 g / dtex, and more preferably about 30 to 40 g / dtex. Specific examples of such high-strength filaments include ultra-high molecular weight polyethylene filaments, wholly aromatic polyamide filaments, heterocyclic high-performance filaments, wholly aromatic polyester filaments, polyarylate filaments, aramid filaments, and polyparaphenylene benzobisoxazole filaments. Among these, so-called ultra-high molecular weight polyethylene filaments with a molecular weight of about 200,000 or more, preferably about 600,000 or more, are preferred.

[0031] The above filaments may contain various known additives, such as pigments, dyes, stabilizers, plasticizers, and lubricants, within the scope of the present invention, and may also contain metal particles or the like to adjust the specific gravity and sedimentation rate.

[0032] The multifilament is composed of a plurality of filaments. The plurality of filaments may be simply aligned, twisted, or braided. The multifilament may be composed of filaments of the same material, or may be a combination of filaments of different materials. For example, it may be combined with metal fibers. The filaments and multifilaments are not limited to those of a specific thickness. For example, by assembling about 5 to 1600 filaments of about 0.3 to 10 dtex, a multifilament of about 5 to 1600 dtex can be used.

[0033] When the core yarn is a twisted yarn, multiple filaments are twisted together to form a twisted yarn using a general-purpose twisting machine such as a double twister, ring twister, up twister, etc. The twist direction may be right-handed (S twist) or left-handed (Z twist), and the twist number may be a soft twist of 500 T / m or less, a medium twist of 500 to 1000 T / m, a strong twist of 1000 to 2500 T / m, or an ultra-strong twist of 2500 T / m or more. The twisting style can be single-twisted yarn, which is "two or more threads pulled together and twisted to the right or left," or multiple-twisted yarn, which is "two or more threads with a single twist (soft or medium twist) pulled together and then twisted in the opposite direction to the single twist," or double-twisted yarn, which is "two or more threads with a single twist (hard twist) pulled together and then twisted in the opposite direction to the single twist," or wall-twisted yarn, which is "a thick single-twisted thread pulled together and a thin, untwisted thread pulled together and twisted in the opposite direction to the single twist," or decorative-twisted yarn, which is "repeated wall-twisted yarn several times to create knots or loops in the thread." [Example]

[0049] Next, three examiners carried out tests on the following items for each of the guide line protection yarns of Examples 1 to 7 and Comparative Examples 1 to 7.

[0050] [Workability] A fishing line 16 made of No. 10 ultra-high molecular weight polyethylene fiber (0.54 mm diameter) was threaded through the end opening 15a of the needle 15 shown in Figure 4, as shown in Figure 5. The tip of the needle 15 was passed through the fishing line at a right angle to the longitudinal direction of each of the guide line protection threads 14 of the Example and Comparative Examples, penetrating the sheath yarn and reaching the core yarn, entangling the fishing line and core yarn. The time required to pull out the core yarn from one end of each guide line protection thread 14 and insert a 1-meter length of fishing line into the center of the thread was measured. Three subjects each conducted three trials. The average times of a total of nine trials are shown in Tables 1 and 2 below, with results of 3 minutes or less indicated by "◎", 3 to 5 minutes indicated by "◯", 5 to 10 minutes indicated by "△", and 10 minutes or more indicated by "X".

[0051] [Holding ability] As described in the workability section above, three test subjects each tried 10 times to determine whether or not a No. 10 ultra-high molecular weight polyethylene fishing line (0.54 mm diameter) could be inserted into the center of the line during the process of pulling out the core thread from one end of each of the guide line protection threads of the Examples and Comparative Examples. That is, out of a total of 30 trials, cases in which the fishing line did not come off are indicated by a "◎", cases in which the fishing line came off once are indicated by a "◯", cases in which the fishing line came off twice are indicated by a "△", and cases in which the fishing line came off three or more times are indicated by an "X", as shown in Tables 1 and 2 below.

[0052] [Fluffing / Unraveling] In all of the above-mentioned workability trials, the sheath yarn of each guide line protection yarn in the Examples and Comparative Examples was observed to see whether it had fuzz or frayed. The results are shown in Tables 1 and 2 below, with "◯" indicating that no fuzz or fraying was observed in any of the trials and "×" indicating that fuzz or fraying was observed in one or more trials.

[0053] [Coating] In all of the above-mentioned workability trials, the cases where the 1 meter of fishing line inserted into the center of each of the fishing line protection threads in the Examples and Comparative Examples was completely covered by the fishing line protection thread and the fishing line could not be seen were indicated with an "O", and the cases where in at least one trial the 1 meter of fishing line inserted into the center of each of the fishing line protection threads in the Examples and Comparative Examples was not completely covered by the fishing line protection thread and part of the fishing line could be seen or part of the fishing line protection thread was loose were indicated with an "X", and these are shown in Tables 1 and 2 below.

[0054] [Table 1]

[0055] [Table 2]

[0056] As shown in Table 1, the guide yarn protection yarns of Examples 1 to 6 are excellent in all aspects of workability, holdability, fluff / fraying, and covering ability. The guide yarn protection yarn of Example 7 is slightly inferior in holdability compared to the guide yarns of the other Examples because the core yarn is a twisted yarn, but is excellent in workability, fluff / fraying, and covering ability.

[0057] However, since Comparative Example 1 was not a composite yarn consisting of a core yarn and a sheath yarn, workability was poor and fluffing was observed. Comparative Example 2 has poor workability because the number of core yarn braids is small. In Comparative Example 3, the number of twists in the core yarn was small, so workability was poor and fluffing was observed. In Comparative Example 4, the sheath yarn was thin, and therefore workability and covering properties were poor. In Comparative Example 5, the core yarn was thin, and therefore workability was poor. In Comparative Example 6, the core yarn was thick, and therefore the covering property was poor. In Comparative Example 7, the sheath yarn had few braids, and therefore the covering property was poor. [Explanation of symbols]
