Description

  The present invention relates to an aquatic material used for aquaculture and fish culture, and more particularly to a suitable aquatic material incorporating a large amount of graphite silica.

  In general, in the fishery industry, where nori and fish are cultivated, it is possible to promote the growth of organisms such as seaweed and fish in order to improve production efficiency, or to improve the habitat and eventually grow the organisms themselves. Attempts have been made to promote.

  On the other hand, graphite silica has recently attracted attention as having a positive effect on the maintenance and growth of living organisms. Graphite silica is thought to have a positive effect on living organisms by emitting far infrared rays and other functions.

  In order to successfully apply the graphite quartz stone having such a function to nori and fish culture, a nori net that has already been proposed (see, for example, Patent Document 1), a net for a sacrifice, a rope, a fiber, and other various types There is a demand to apply graphite silica to fishery materials made of fishing gear.

Japanese Patent No. 3217390

  However, some fishing gears used as fishery materials are long and have a large tensile force such as ropes, nets and fibers.

  When trying to form such a long marine material, for example, with a material in which graphite silica is kneaded into a resin and mixed almost uniformly, there is a part that exerts an effect to withstand the tensile force acting on fibers, ropes and nets. Because it is only the resin part, if the amount of graphite silica to be kneaded is large, fibers, ropes and nets are easily cut by a small tensile force, so the mixing amount of graphite silica will be kept low. There was an inconvenience. Furthermore, in the production process in which these marine materials are formed into fibers or ropes with resin, a large stretching force is imparted in the longitudinal direction to forcibly stretch, so the mixing amount of graphite silica can be kept low. It was something that would end up. Thus, if the mixing amount of graphite silica is kept low, there is a disadvantage that the function of exerting a positive influence on the survival of the organism is also kept relatively low.

  Furthermore, it is also considered that the function of exerting a positive effect on the survival of living organisms possessed by graphite silica is exhibited by the generation of an electron flow when graphite silica touches water directly. However, when graphite silica is kneaded in the resin, graphite silica other than graphite silica exposed on the surface does not come into direct contact with water, and the function of exerting a positive effect on the survival of living organisms is not fully exhibited. There was an inconvenience.

  Therefore, the present invention has been made in view of these points, and it is possible to greatly increase the growth of fish and laver by holding a large amount of graphite silica in direct contact with water, and in the form of fibers, ropes, It is intended to provide fishery materials that have high tensile strength as fisheries materials such as nets, and that do not cause cutting even when processed into fishery materials. It is.

  In order to achieve the above-described object, the marine material of the present invention according to claim 1 is a marine material formed of at least one strand, and graphite silica is put into water in at least one strand. It is characterized by being held in direct contact.

  The marine material of the present invention according to claim 2 is characterized in that the graphite silica is held between a plurality of yarns constituting a strand.

  Moreover, the fishery material of the present invention according to claim 3 is characterized in that the fishery material is formed in a rope shape or braid shape.

  Moreover, the fishery material of the present invention according to claim 4 is formed in a net shape using the fishery material according to claim 3.

  Since the fishery material of the present invention is configured in this way, it can hold a large amount of graphite silica so that it touches the water directly, and can greatly improve the growth of fish and laver, and it is fibrous, rope-like In addition, it has high tensile strength as a fishery material such as a net-like material, and also exhibits excellent effects such as no cutting or the like even when processed into a fishery material and excellent workability.

  Hereinafter, embodiments of the present invention will be described with reference to FIGS.

  1 and 2 show an embodiment of the fishery material of the present invention.

  The fishery material 1 of this embodiment shown in FIG. 1 is formed in a twain shape. More specifically, a plurality of strands 3 and 3 formed by twisting a plurality of yarns 2 and 2 are further twisted to form a twain 4. And at least one (all in this embodiment) strand 3 is a graphite silica formed in a fine powder form between yarns 2 when twisting a plurality of yarns 2, as shown in FIG. 5 is twisted so that the graphite silica 5 is held between the yarns 2. As a result, the powdery graphite silica 5 can directly touch the water entering through the yarn 2.

  When the fishery material 1 thus formed is used further, the tween 4 shown in FIG. 1 is used as it is, or a plurality of tweens 4 and 4 are further twisted to form a rope shape, Alternatively, the strand 3 may be formed in a braid shape. Usually, the strand 3, the twein 4 and the rope are preferably reversed in order of the S · Z twist direction of the yarn 2, the strand 3 and the yarn 4. Moreover, it is good also as the same direction, without changing a twist direction.

  As a material of the yarn 2, a resin material generally used for fishery materials may be used. Moreover, as a yarn, a conventionally well-known thing can be utilized and the filament yarn classified into the shape form (further classified into the multifilament yarn and the monofilament yarn) and the spun yarn can be used. Further, as the yarn 2, a slit yarn (also referred to as a flat yarn) or a split yarn made of a synthetic resin film can be used in addition to the thread-like material. One slit yarn is formed by cutting a synthetic resin film into a narrow width and stretching it. The other split yarn is obtained by fibrillating one slit yarn, applying an impact action thereto, and generating innumerable fissures in the longitudinal direction to form an aggregate of fibers. It is preferable to form the yarn by twisting fine particles or powder of graphite silica into such split split yarn. In order to twist graphite silica between yarns 2, twist a material with graphite silica 5 attached to the outer surface of yarn 2 together with a water-soluble adhesive so as to dissolve the water-soluble adhesive when used in water. It may be. Furthermore, it is preferable to wrap the graphite silica 5 in the strand 3 as a result of wrapping the graphite silica 5 in a thin wide yarn 2.

  In order to form the net-like fishery material 6, as shown in FIG. 3, a rope-like or braid-like fishery material 1 may be used as the net legs 7.

  As described above, the fishery materials 1 and 6 of the present invention hold the graphite silica 5 in at least one strand 2 so as to be able to come into direct contact with water. Electrons can be made to flow into the water that touches the water, and the effect of promoting the growth of living organisms and the health of the living environment of the graphite silica 5 can be fully demonstrated, greatly improving the growth of fish such as fish and laver. Can be made. Further, strength such as tensile strength as the marine materials 1 and 6 is ensured by making the material of each yarn 2 forming the strand 3 a resin material generally used for marine materials. Yes. Alternatively, the strand 3 may be used as a fishery material in the shape of a single strand before the strand 3 is formed with the twain 4.

  In addition, for example, when the nori net is used to produce a laver net using the net-like fishery material 6 shown in FIG. 3 and used for nori cultivation in the Ariake Sea, nori is healthy in the nori net as the aquatic material 6 of the present embodiment. And it grew well in large quantities. However, in the conventional general laver net as a comparative example that does not use the laver net of this embodiment, a disease such as redness caused by laver occurred. When the laver harvested by the laver net of this embodiment was produced as laver laver, the highest quality laver was obtained. It is considered that these are synergistically acting on the biological growth promotion function, water purification function, etc. of the graphite silica 2 held in a large amount inside the strand 3.

  The fishery material of the present embodiment is widely used, and can be applied to portions where long objects such as laver nets, nets surrounding fish reefs, nets for sacrifices, and ropes are used for fisheries.

  In addition, this invention is not limited to embodiment mentioned above, A various change is possible as needed.
