  The present invention relates to a fiber yarn suitable for fishing lines and the like.

  Conventionally, for the purpose of improving the wear resistance of fiber yarns used as fishing lines, as a method of improving the slipping properties of fiber yarns, a method of imparting oil to the yarns to improve the slipping after the spinning or drawing process Alternatively, a method of kneading a silicon compound, a lubricant or the like at the time of spinning has been performed (for example, see Patent Document 1).

JP 2006-115802 A

  Among the conventional methods as described above, in the fiber yarn obtained by the method of applying an oil agent or the like after the spinning or drawing step, a liquid oil film is formed on the surface. For example, when it is used as a fishing line, it is removed immediately by contact with a rod guide or a reel, resulting in poor durability.

  In addition, the method of kneading silicon compounds or lubricants during spinning cannot be used to select the original yarn, so it is not suitable for the production of small quantities of various types of fiber yarn such as fishing line. When post-processing is performed, there is a problem that slippage is likely to occur with a guide or the like, so that workability is remarkably inferior and productivity is poor.

  The present invention has been made in view of such a current situation, and provides a fiber yarn that can improve the abrasion resistance of the fiber yarn, can be easily manufactured, and has a durable coating. This is the issue.

  As a result of intensive investigations to solve such problems, the inventors of the present invention applied a fat or oil to the surface of the fiber yarn, and further added a solidifying agent or gelling agent to solidify or gel the film. The present inventors have found the fact that the wear resistance is improved and also has durability, and have further studied to complete the present invention.

That is, the present invention

It is related with the manufacturing method of the fiber yarn of any one of preceding clause [2]-[10] characterized by the above-mentioned.

  According to the present invention, a fiber yarn having improved wear resistance due to good sliding properties is provided. In the fiber yarn having the coating provided by the present invention, the coating that contributes to the improvement of wear resistance can be easily formed and has durability. Moreover, since this film | membrane can also be formed using used edible oil, in this aspect, it is excellent also in ecology. The fiber yarn having the coating according to the present invention having such excellent features can be used for various applications, for example, for industrial materials such as nets and ropes used on land or in water, and for leisure goods. . The fiber yarn having a film according to the present invention is particularly suitable as a fishing net or fishing line used in water, and particularly suitable as a fishing line, and can form the film using a less harmful oil or fat. Therefore, even if the film component is gradually released into the water during use, the harm to the natural environment can be reduced as compared with those using conventional silicon compounds.

Hereinafter, the present invention will be described in detail.
The fiber yarn having the coating according to the present invention (in the present specification, sometimes referred to as “the fiber yarn of the present invention”) has oil or fat solidified or gelated on the surface of the fiber yarn as a substrate. (Hereinafter sometimes referred to as “the film in the present invention”).

  The fiber yarn used as the substrate is not particularly limited, and any yarn made of fibers can be applied. For example, a yarn made of a known synthetic fiber can be appropriately selected and used according to the purpose. Specific examples of synthetic fibers include, for example, aliphatic polyamides, aromatic polyamides, aromatic polyesters, aliphatic polyesters, polyolefins, polyurethanes, and the like, or recycled products of these synthetic fibers. Is mentioned. Of these, for example, polyamide fibers are considered if wear resistance is considered, polyester fibers are considered if dimensional stability is considered, and aliphatic polyester fibers are considered if elasticity is considered if biodegradability is considered. In view of lightness, the polyurethane fiber is preferably a polyolefin fiber having a light specific gravity. Particularly when used as a fishing line, polyamide fibers, polyester fibers, high molecular weight polyethylene fibers excellent in sensitivity and high strength, and the like are preferable.

  Further, if necessary, two or more kinds of synthetic fibers as described above can be used in any combination, and furthermore, a core-sheath type, a side-by-side type, a sea-island type, etc., formed from two or more types of resins. Bicomponent fibers can also be used. In addition, generally used flame retardants, colorants, pigments, lubricants, weathering agents, antioxidants, heat resistance agents, and the like may be appropriately added to the synthetic fibers. The fiber raster is arbitrary, and may be bright, semidal, or fulldal, and can be adjusted by appropriately increasing or decreasing the content of additives such as titanium oxide.

  Further, the synthetic fiber may be either a long fiber or a spun yarn, but a long fiber is preferable because of its excellent wear resistance and strength. Monofilament, multifilament, twisted yarn, braided string and the like can be appropriately selected as the form of the fiber yarn composed of long fibers. Further, as the fiber yarn, for example, a processed yarn that has been subjected to processing such as false twisting for the purpose of imparting stretchability may be used. Further, a fiber yarn in which a resin such as a heat sealing resin is impregnated between the constituent filaments may be used.

  The strength of the synthetic fiber may be appropriately set according to the purpose. For example, in a fiber yarn used for fishing line, a synthetic fiber having a linear strength of 5 cN / dtex or more and a knot strength of 2.5 cN / dtex or more. Fiber is preferred.

  Next, with respect to the cross section of the fiber yarn, the area to which the film in the present invention is applied is increased, and furthermore, the yarn is made to have an irregular cross section as a whole, because the film is difficult to remove due to the anchor effect. Is preferably a cross-section having irregularities and grooves on the outer peripheral surface in contact with another object. In the present specification, the cross section of the fiber yarn and the cross section of the filament mean a cross section perpendicular to the fiber axis direction.

  In the case of multifilaments, the gap between the constituent filaments appears on the surface, so that even if the cross section of each constituent filament is a round cross section, the effect is the same as if there are irregularities or grooves on the outer peripheral surface of the yarn Can be expressed. Furthermore, in the case of twisted yarn, by setting the single filament fineness and the number of twists of the constituent filament as appropriate, in the case of braid, by appropriately setting the single filament fineness and the braid angle of the constituent filament, The surface area and the degree of unevenness can also be adjusted. Of course, even if it is a multifilament, it cannot be overemphasized that cross-sectional shapes other than a round cross section can be employ | adopted as a filament cross-sectional shape of each constituent filament.

  On the other hand, in the case of a monofilament, the filament cross-sectional shape becomes the cross-sectional shape of the yarn as it is, and therefore adopting a deformed cross-sectional shape or a shape having grooves or irregularities on the outer periphery as the filament cross-sectional shape is a fiber yarn Is particularly preferred when is a monofilament. In the present specification, the filament cross section means a cross section of one filament regardless of whether it is a monofilament or a multifilament. Therefore, for example, in a multifilament, the cross section of each component filament is meant. In addition, in the thread | yarn comprised by multiple filaments, such as a multifilament, the cross-sectional shape of each component filament may be the same, and the filament from which cross-sectional shape differs may be mixed.

  The irregular cross section other than the round cross section as the filament cross section is not particularly limited. For example, a triangular cross section, a square cross section, a pentagon cross section, a flat cross section, a wedge cross section, or a C-shaped cross section or an H-shaped cross section in the shape of an alphabet. , I-shaped section, W-shaped section, star-shaped section, gear-shaped section, and the like. Among these, a star-shaped cross section as shown in FIG. 1 and a gear-shaped cross section as shown by a solid line in FIG. 2 are preferable. Further, a flat and star-shaped cross section as shown in FIG. 3 and a flat and gear-shaped cross section are also preferable.

In the case of using an irregular cross section, the degree of irregularity is preferably 1.1 or more, more preferably about 1.1 to 1.3 in order to increase the effect of increasing the surface area and the anchor effect. preferable. For example, as shown in FIG. 2, the irregularity is a value calculated as r ₂ / r ₁ when the radius of the inscribed circle in the filament cross section is r ₁ and the radius of the circumscribed circle is r ₂ . Therefore, as a specific method for measuring the degree of irregularity, the fiber is cut perpendicularly to the fiber axis using a safety razor or the like, and the resulting cross-sectional shape is optical microscope or scanning type at a magnification of 200 times, for example It is possible to adopt a method of forming an image with an electron microscope, measuring the inscribed circle diameter r ₁ and the circumscribed circle diameter r ₂ from the image, and calculating the degree of irregularity of the fiber by r ₂ / r ₁ .

  The means for obtaining the irregular cross-sectional shape is not particularly limited, and a known means may be adopted as appropriate. For example, there are a so-called direct spinning method using a base devised so that a deformed cross-sectional shape can be obtained directly during melt spinning, a split fiber method, an alkali treatment method during dyeing, and the like. Can also be done in any way.

  The oil or fat for forming the film in the present invention is not particularly limited as long as the solidified or gelled film can improve the abrasion resistance of the fiber yarn, and the fiber yarn of the present invention is not particularly limited. In view of the efficiency of processing for applying oils and fats during production, oils and fats that are liquid at normal temperatures (23 ° C) to about 100 ° C are preferred.

  As the types of fats and oils, any of mineral oils and fats, vegetable or animal natural fats and oils can be used, but considering the slipperiness that the film of the present invention gives to the fiber yarns, mineral oils and fats can be used. Oils and fats are preferred. It is possible to mix a plurality of types of fats and oils, and for example, by mixing natural fats and oils with highly viscous mineral oils and fats, the viscosity can be lowered. The processing speed at the time of providing fats and oils can be increased.

  Mineral oil is an oil component derived from natural petroleum, which is a liquid chemical substance obtained by purification and distillation, and is called petrolatum or paraffin. Specific examples include paraffinic hydrocarbons represented by liquid paraffin, olefinic hydrocarbons, naphthenic hydrocarbons, and aromatic hydrocarbons.

  Examples of vegetable or animal natural fats and oils include 2-ethylhexyl stearate, isopropyl myristate, isopropyl palmitate, normal butyl stearate, isolauryl oleate, oleyl oleate, dioleyl adipate, neopentyl glycol ( NPG) aliphatic esters such as dioleate, trimethylolpropane tri-2-ethylhexanate, pentaerythritol tetrapelargonate, and coconut oil, beef tallow, palm oil, castor oil, rapeseed oil and the like.

In addition, used cooking oil, for example, waste tempura oil, can be used for part or all of the fats and oils, and this has the effect of effectively using resources and reducing waste. Articles can also be made into ecological products that are friendly to the global environment.
Although the reason is not necessarily clear, the present inventor has found that the use of used edible oil rather than a new one may have better workability during film formation because of its lower viscosity. ing.

  The film in the present invention is a film formed by solidifying or gelling the above-described oil or fat, and such solidification or gelling is preferably performed by the action of a solidifying agent or a gelling agent. The reason is that by using a solidifying agent or gelling agent, a substantially irreversible solidified or gelled film that does not become liquid in a normal use state can be formed. Therefore, the film in the present invention preferably contains a solidifying agent or a gelling agent. In addition, it is not necessary to distinguish between a solidifying agent and a gelling agent because fat or oil is solidified or gelled depending on the type and amount of oil used. Can also be an agent.

  The solidifying agent or gelling agent in the present invention is not particularly limited as long as it can solidify or gel the oil and fat, and generally known agents can be used. As the solidifying agent or gelling agent, for example, waxes can be used. Specific examples include carnauba wax, candelilla wax, sugar wax, rice wax, wood wax, bayberry wax, ocully wax, esparto. Plant waxes such as waxes, animal waxes such as beeswax, insect wax, whale wax, shellac wax and lanolin wax, petroleum waxes such as paraffin wax and microcrystalline wax, mineral waxes such as montan wax, ozokerite wax and ceresin Synthetic waxes such as wax, Hoechst wax, polyethylene wax, carbo wax, caster wax, Fischer-Tropsch wax, and kesol wax may be mentioned. Furthermore, higher fatty acids and higher aliphatic alcohols obtained by hydrolyzing the animal and plant waxes, and synthetic esters thereof can also be used as a solidifying agent or a gelling agent.

  In addition, a formalin condensate or a higher aliphatic sulfate of an alkyl group-substituted or unsubstituted aryl sulfonate can be used as a solidifying agent or a gelling agent. Specifically, as formalin condensates of alkyl group-substituted or unsubstituted aryl sulfonates, commercially available products such as Mighty 100 (trade name, manufactured by Kao Corporation), Demall (trade name, manufactured by Kao Corporation) and the like are available. Examples of the higher aliphatic sulfate include sodium dodecylbenzenesulfonate, sodium lauryl sulfate, and sodium dodecyl sulfate, and examples of the higher fatty acid salt include sodium myristate, sodium palmitate, and sodium stearate. .

  Furthermore, as a method for gelling oils and fats, a method of adding metal soap and a small amount of water, a method of using a condensate of polyol and benzaldehyde, a method of adding an O / W type surfactant and a small amount of water, etc. should be adopted. You can also.

  Of the wide variety of solidifying or gelling agents as described above, preferred are fatty acids, especially higher fatty acids (meaning fatty acids having 12 or more carbon atoms), and particularly preferred is 12-hydroxystearic acid. . This 12-hydroxystearic acid can be obtained by, for example, hydrogenating and decomposing castor oil taken from castor bean seeds, is derived from plants, is environmentally friendly, is inexpensive and is available as a commercial product. For example, according to the knowledge of the present inventor, “Tempered Temple (trade name)” (manufactured by Johnson) sold as a solidifying agent for waste edible oil for general consumers is mainly composed of 12-hydroxystearic acid. .

  One kind of solidifying agent or gelling agent may be used, or two or more kinds may be used in combination.

  The ratio of the oil and fat to the solidifying agent or the gelling agent depends on the type of the oil and fat and the solidifying agent or the gelling agent, but the solidifying agent or the gelling agent is 2 to 10 parts by mass with respect to 100 parts by mass of the oil and fat. It is preferable.

  As a method for forming a film in the present invention, after applying fats and oils to the fiber yarn, the fats and oils may be solidified or gelled by further adding a solidifying agent as necessary. An oil and fat composition to which an agent is added may be prepared in advance and applied to the fiber yarn. However, since the latter method is restricted by the pot life of the composition, a preferable method is to apply fats and oils to the surface of the fiber yarn and then add a solidifying agent or gelling agent.

  The processing method for imparting the oil or fat composition to the fiber yarn may be in accordance with a method generally known as a method for imparting an oil to the fiber, and this can be performed using a conventional processing machine. . Processing temperature and processing speed can also be set arbitrarily, and if necessary, the oil or fat composition may be subjected to processing in a state heated to a temperature higher than room temperature. The properties of the oil or fat composition to be applied to the fiber yarn are not particularly limited, and may be straight or emulsion, and the ionicity may be appropriately selected according to the type of fiber yarn and the processing machine.

  In addition, in order to improve the uniformity of adhesion to the fiber yarn, lower alcohols such as ethanol and isopropyl alcohol, oxide compounds such as ethylene oxide and propylene oxide, etc. may be added to the oil or fat composition. Depending on the case, an antistatic agent may be added. Examples of the antistatic agent include anionic surfactants such as alkyl sulfates, fatty acid soaps, alkyl sulfonates, and alkyl phosphate esters. When the antistatic agent is used, the amount used is not particularly limited, but is generally about 3 to 15% by mass of the mass of all components used for forming the film in the present invention. In addition, antioxidants, preservatives, wettability improvers and the like may be added to the oil or fat composition as necessary. For example, when used as a fishing line or fishing net, an additive such as a fragrance having a fish collecting effect may be included in the film of the present invention.

  Furthermore, the processing method for imparting a solidifying agent or gelling agent as required is in accordance with the processing method for imparting the above-described oil or fat composition.

  In the production of the fiber yarn of the present invention, it is optional at any stage of the production process to apply the oil or fat composition to the fiber yarn and, if necessary, to apply a solidifying agent or a gelling agent. However, if productivity is taken into consideration, it is preferable to carry out at the final stage of processing.

  The amount of the coating in the present invention formed as described above is generally based on 100 parts by mass of fiber yarn (here, it means a fiber yarn having no coating) although it depends on the shape of the fiber. The film mass is preferably 3 to 30 parts by mass, and more preferably 5 to 25 parts by mass.

  The film is preferably formed on the entire outer surface of the fiber yarn, but it is not always necessary to have the film on the uneven outer surface with a thickness exceeding the peak of the unevenness, for example, as shown in FIG. Instead, as shown in FIG. 5, a certain effect can be obtained even when the film has a thickness sufficient to fill the recess. Therefore, for example, even if what was initially in the state shown in FIG. 4 becomes the state shown in FIG. Of course, it may be in the state shown in FIG. 4 from the beginning.

Next, an Example is given and this invention is demonstrated concretely.
[Example 1]
Ultra high molecular weight polyethylene multifilament (“Dyneema (registered trademark) SK60” manufactured by Toyobo Co., Ltd., 110 dtex / 96f) was stringed in four to obtain a 462 dtex braided fiber yarn. By heating 600 ml of salad oil consisting of soybean oil and rapeseed oil (Nisshin Oillio Group Co., Ltd.) to 100 ° C., adding 18 g of a solidifying agent (“Tempered Temple (trade name)” manufactured by Johnson Co., Ltd.) Immediately after preparing the oil / fat composition, the fiber yarn is immersed in the oil / fat composition, and then the excess oil / fat composition is removed by shave processing, followed by natural cooling at room temperature (15 ° C.). A solidified film of fat was formed on the surface. In the fiber yarn having the film thus obtained, the fineness of the fiber yarn excluding the film was 462 dtex, whereas the total fineness actually measured including the film was 527 dtex.
