Since the development of such automated machines, wires have come to be used due to ease of handling, machine adaptability, tightening properties, durability, and the like. [0004] However, since the wire is attached to the above-mentioned automated machine, when the wire is changed to a normal wire, rigidity and hardness per thickness are large, lack flexibility, and handling is difficult. There is also manganese, chromium,
There is a problem that metal components such as nickel may be eluted into seawater. From such a problem, there has been a strong demand from the industry for the development of a wire having excellent handleability and less elution of metal components into seawater. SUMMARY OF THE INVENTION The present invention solves the above-mentioned conventional problems. In adapting the present invention to a machine for automatically attaching a seedling to a rope, the handleability is easy and the tightening property is excellent.
It is an object of the present invention to provide a seed and shellfish attachment wire that has excellent durability to withstand long-term cultivation and has less concern about elution of metal components. [0006] In order to achieve the above object, a wire for attaching seedlings of the present invention is a linear body for attaching seedlings to a rope used for cultivation of edible shellfish. In the linear body, the surface of the stainless steel wire is roughened and covered with a primer, the surface is covered with a resin coating , and the resin of the resin coating has a water absorption coefficient.

The diameter of the body is not less than 0.3 mm and not more than 2.0 mm . In the above structure, the surface roughness of the stainless steel wire is preferably in the range of 0.1 to 100 μm in average surface roughness (Rz) according to the measurement method of JIS-B0601. Particularly preferred average surface roughness (Rz) is 1 to
It is in the range of 20 μm. [0008] In the above construction, the primer comprises :
Oil primer mixed with oil varnish and rust preventive pigment, transparent
Lacquer primer mixed with bright lacquer and anti-rust pigment
It is preferably at least one selected from [0009] The good Ri Specifically, phthalic acid primer, melamine alkyd primer, a vinyl primer, epoxy primers, urethane primer, Jin chloro formate primer, mixing at least one with anticorrosive pigment selected zinc-rich primer, a wash primer Are preferred . According to the structure of the present invention described above, a linear body for attaching seedlings to a rope used for cultivation of edible shells is provided, wherein the linear body has a stainless steel wire surface. The surface is roughened and covered with a primer, and its surface is covered with a resin coating, so that it is easy to handle when used for a machine that automatically attaches seedlings to ropes, and has excellent tightening properties. It is possible to obtain a wire for attaching seedlings and shellfish which has excellent durability to withstand long-term cultivation and is less likely to elute metal components. In addition, due to the synergistic effect of the surface roughening of the stainless steel wire and the presence of the primer,
Excellent in the integrity of stainless steel wire and resin coating. In the above, when the resin of the resin film is made of a polyamide resin having a water absorption of 1.0% or less, the coating thickness is 50 μm or more and 250 μm or less, and the entire diameter is 0.3 mm or more and 2.0 mm or less. Further, it is possible to provide a seed and scallop mounting wire that is easy to handle, has excellent tightening properties, has excellent durability for long-term cultivation, and has little concern about elution of metal components. In the above, the water absorption was determined by a method of treating in water for 24 hours (ASTM D570). 50 thickness
If it is less than μm, the coating layer is damaged and the wire base is easily exposed. On the other hand, if the thickness exceeds 250 μm, the handleability tends to decrease, and the tightening property tends to decrease. In the above, when the surface roughness of the stainless steel wire is in the range of 0.1 to 100 μm in average surface roughness (Rz) according to the measurement method of JIS-B0601, the stainless steel wire, the primer and the resin coating are used. And the unity is improved. In the above, when the primer is at least one selected from an oil primer obtained by mixing an oil varnish and a rust preventive pigment, and a lacquer primer obtained by mixing a transparent lacquer and a rust preventive pigment, the stainless steel wire and the resin coating may be used. And the rust resistance of the stainless steel wire is also improved. The present invention will be described more specifically with reference to the following examples. In the present invention, as the stainless steel wire,

It is in the range of 0 to 1.50 mm. The surface roughening of the stainless steel wire is
This is performed by a method called a sand blast method. This uses a dry method in which pressure is applied to a sandbox containing particles such as mountain sand, river sand, slag (kalami), silicon carbide, alumina, cast iron grit, shots, and ceramics, and the sandbox is sprayed onto a workpiece. This cleans and roughens the substrate surface of the object to be processed. Although the surface roughness depends on the particle size of the particles used, JIS-B0601
0.1 to 100 μm in surface roughness (Rz)
Is preferably within the range. More preferably, it ranges from about several microns to several tens of microns. In addition to the dry method, the surface can be roughened by a wet method such as a water jet method in which particles are sprayed together with water, a liquid honing method, or a method using a chemical means. At the stage where the surface roughening is completed, residual particles are completely removed from the surface by a vacuum cleaner or the like. Thereafter, the primer treatment is immediately performed. This treatment is important from the viewpoint of improving the adhesion of the coating to the resin to be performed thereafter and preventing rust. There are two types of primers, oily and lacquer. The oil primer is a mixture of an oil varnish and a rust-preventive pigment, and the lacquer primer is a mixture of a transparent lacquer made for a primer and a rust-preventive pigment. In addition to lacquer primers and oil primers, those mainly aimed at simply improving the adhesion to resins include phthalic acid primers, melamine alkyd primers, vinyl primers, epoxy primers, urethane primers, and zinc chloride Primers, zinc-rich primers, wash primers and the like may be used. The treatment of these primers is performed by a spray method,
It may be applied with a brush or the like, but in the present invention, adoption of the dipping method of immersion and drawing is advantageous in terms of cost and prevention of variation in quality. After the primer treatment, moisture and solvents are sufficiently removed by drying. Then, it is coated with a hot-melt resin by a commonly used resin-coated wire extrusion molding machine. As the resin, polyamide resin, particularly nylon 11, nylon 12, nylon 610 having a water absorption of 1.0% by weight or less is advantageous from the viewpoint of flexibility and durability of repeated bending.
