Description

[Detailed Description of the Invention] The present invention relates to a tortoise shell-shaped net-like body made of synthetic resin and having excellent durability and strength, whose longitudinal ends are securely fixed.

Conventionally, wire meshes made of metal wires such as iron wires have been used as nets for cages for aquaculture, but these have problems in terms of durability because they are severely corroded by rust.

The inventors of the present invention previously proposed a tortoise-shell-shaped mesh consisting of continuous hexagonal meshes made by twisting synthetic resin monofilaments as a highly durable and strong mesh to replace such a wire mesh. This tortoise-shell-shaped reticular body, for example, as shown in its plan view in Figure 1,
It is made by intersecting and twisting a plurality of synthetic resin monofilaments, each mesh 3 having at least two twist turns 2 and the rest formed from straight sides 1 consisting of the monofilaments themselves. However, this tortoiseshell-shaped net is machined with the vertical direction in the direction of the arrow in Figure 1, but since the strength of both ends in the vertical direction is weak, the ends unravel during use, which has a negative effect on the strength of the net. It often causes

The inventors of the present invention conducted studies aimed at improving this point, and as a result, they came up with a hexagonal mesh structure that securely fixes the longitudinal ends and prevents the mesh from collapsing at the ends. In other words, the present invention is a tortoiseshell-shaped network body with a continuous hexagonal network formed by twisting together multiple synthetic resin monofilaments.
The longitudinal ends are bent in parallel so that at least two meshes overlap, and each side perpendicular to the end of each overlapped mesh is made of a synthetic resin thicker than the monofilament constituting the network. The present invention provides a hexagonal-shaped net-like body made of synthetic resin whose ends are alternately sewn parallel to each other with at least one monofilament filament or stranded wire.

The tortoiseshell-shaped network of the present invention is produced by heating a plurality of synthetic resin monofilaments to a temperature below their melting point, intersecting each other, twisting and weaving them, and then cooling them.
Manufactured by fixing the shape. The synthetic resin monofilaments used here as the material for the net are nylon 6, nylon 66, nylon
Polyamide resins such as 610 and nylon 612, polyester resins such as polyethylene terephthalate and polybutylene terephthalate, polyvinylidene halides resins such as polyvinylidene chloride and polyvinylidene fluoride, and polyolefin resins such as polyethylene and polypropylene. It is made by melt-spinning a plastic polymer and stretching it as necessary, and its thickness is usually about 0.5 mm.
~3mm.

Next, the tortoiseshell-shaped reticular body of the present invention will be explained in detail with reference to the drawings. FIGS. 2 and 3 show end plan views of the tortoiseshell-shaped net-like body of the present invention. To form the ends of such a hexagonal mesh, first, as shown in FIG. At least two meshes should overlap each other.
Next, each side perpendicular to the end of each superimposed mesh,
That is, by stitching the twisted sides 2 parallel to the ends with fixed lines 4 made of synthetic resin monofilament lines or strands that are thicker than the monofilament forming the net-like body, as shown in FIG. A tortoiseshell meshwork with securely fixed ends of the embodiment is completed.

The fixed wire 4 used in the present invention is thicker than the monofilament forming the network, preferably the second
It is a synthetic fiber monofilament line having a diameter twice or more, or a strand made by twisting the same, and the material thereof may be the same as the monofilament forming the network or may be different. Such fixed wires are even harder and less flexible than the monofilament forming the mesh, so if they are inserted alternately into the strands of the overlapped ends while being sewn together, the superimposed meshes will is firmly fixed. Since the outermost end of the net is fixed inside the net in the longitudinal direction and is not left open, the end is effectively prevented from unraveling during use. FIG. 3 shows another aspect of end fixing, in which another fixing wire 4' is inserted into the folded portion of the net-like body. According to this aspect, the mesh at the folded portion is not lifted up, so that more effective fixing can be achieved.

The tortoiseshell-shaped net of the present invention thus formed has ends that are securely fixed, has excellent durability and strength, and can be widely used as outdoor nets, fences, aquaculture nets, and the like.
