DETAILED DESCRIPTION OF THE INVENTION

[0019] Referring to FIGS. 3-5, a composite thread cable 21 for an aquaculture cage 20 in accordance with the preferred embodiment of the present invention comprises multiple multi-filament polyester fiber yarn wires 22 and at least one or more than one copper alloy wire 23 blending and interweaving with the multi-filament polyester fiber yarn wires 22. Each of the multi-filament polyester fiber yarn wires 22 is made of flexible material. The at least one or more than one copper alloy wire 23 is made of hard material. The at least one or more than one copper alloy wire 23 is intertwined in the multi-filament polyester fiber yarn wires 22 tightly and closely to construct the composite thread cable 21.

[0020] In the preferred embodiment of the present invention, each of the multi-filament polyester fiber yarn wires 22 is made of plastic material.

[0021] In the preferred embodiment of the present invention, the multi-filament polyester fiber yarn wires 22 have a number more than that of the at least one or more than one copper alloy wire 23.

[0022] In the preferred embodiment of the present invention, each of the multi-filament polyester fiber yarn wires 22 is made of Mono nylon, Multi-Mono nylon, Polyethylene, Nylon, Knotless, tetoron or Dyneema.

[0023] In the preferred embodiment of the present invention, the at least one or more than one copper alloy wire 23 is encompassed by the multi-filament polyester fiber yarn wires 22.

[0024] Referring to FIGS. 1 and 2 with reference to FIGS. 3-5, a method for molding a composite thread cable 21 in accordance with the preferred embodiment of the present invention comprises a first step (a), a second step (b), a third step (c), a fourth step (d) and a fifth step (e).

[0025] The first step (a) includes providing a determined amount of copper alloy staple in a melting furnace, adding a determined amount of metallic element in the melting furnace, and melting and kneading the copper alloy staple and the metallic element at a high temperature to form a copper alloy melting liquid X. The copper alloy staple contains an electrolytic copper with a high purity. The metallic element has a high tensile strength, is erosion resistant and is wear resistant.

[0026] The second step (b) includes filling the copper alloy melting liquid X into a casting furnace 51 to directly form a copper alloy embryo material X1 by a casting process 5.

[0027] The third step (c) includes stretching the copper alloy embryo material X1 by a tensile process to form a copper alloy wire 23 with a determined diameter.

[0028] The fourth step (d) includes blending and interweaving at least one or more than one copper alloy wire 23 with multiple multi-filament polyester fiber yarn wires 22 by a determined proportion. Each of the multi-filament polyester fiber yarn wires 22 is made of flexible material. The at least one or more than one copper alloy wire 23 is made of hard material. The multi-filament polyester fiber yarn wires 22 have a number more than that of the at least one or more than one copper alloy wire 23.

[0029] The fifth step (e) includes intertwining the at least one or more than one copper alloy wire 23 in the multi-filament polyester fiber yarn wires 22 tightly and closely to construct a composite thread cable 21 which contains the at least one or more than one copper alloy wire 23 and the multi-filament polyester fiber yarn wires 22.

[0030] The composite thread cable 21 is customized to make an aquaculture cage 20.

[0031] In practice, the at least one or more than one copper alloy wire 23 of the composite thread cable 21 has a natural antibacterial function. Thus, when the at least one or more than one copper alloy wire 23 touches the air, the at least one or more than one copper alloy wire 23 is oxidized to release the copper ions. At the same time, the multi-filament polyester fiber yarn wires 22 absorb the copper ions to achieve an antibacterial effect. Thus, the composite thread cable 21 has an antibacterial effect by provision of the at least one or more than one copper alloy wire 23, to improve the antibody, to inhibit the parasites and pathogens, and to reduce the amount of chemicals and antibiotics. In addition, the composite thread cable 21 prevents breeding and adhesion of marine organisms by action of the at least one or more than one copper alloy wire 23, so as to prevent the growth of the marine organisms. Further, by action of the at least one or more than one copper alloy wire 23, the composite thread cable 21 has an enhanced dissolved oxygen (DO), so as to improve the water circulation, and to keep a high oxygen content. Further, by action of the at least one or more than one copper alloy wire 23, the composite thread cable 21 has a high tensile strength, is erosion resistant to the sea water and is wear resistant. Further, the at least one or more than one copper alloy wire 23 is encompassed by the multi-filament polyester fiber yarn wires 22, to decrease the surface friction. Further, the composite thread cable 21 is flexible, is not broken easily and has a light weight by provision of the multi-filament polyester fiber yarn wires 22. Further, the composite thread cable 21 has a determined hardness by provision of the at least one or more than one copper alloy wire 23 and has a determined flexibility by provision of the multi-filament polyester fiber yarn wires 22, so that the composite thread cable 21 has great support strength and durability. Further, the composite thread cable 21 is assembled to construct the aquaculture cage 20 easily and conveniently, thereby simplifying the operation procedures, and decreasing the cost of assembly.

[0032] Although the invention has been explained in relation to its preferred embodiment(s) as mentioned above, it is to be understood that many other possible modifications and variations can be made without departing from the scope of the present invention. It is, therefore, contemplated that the appended claim or claims will cover such modifications and variations that fall within the scope of the invention.
