Description

Technical Field

[0001] The invention discloses a production process of a flat tensile-resistant fishing net, belonging to the field of fishing nets. Background Art

[0002] Fishing net is a net structure used for aquaculture or fishing.

[0003] Due to the limitation of the existing process, the edges of the existing fishing nets are shorter than the middle area of ​​the fishing net. When several fishing nets of standard width are stitched together to form a large fishing net, the entire fishing net will have uneven ridges and depressions. At this time, the pulling force of the fishing net in the water is all exerted through the edges. When the edges are pulled, the middle part of the fishing net is uneven, which will cause the overall resistance to increase. In addition, the concave fishing net is easy to cause the accumulation of fish, causing the force of the entire fishing net to be concentrated in the same area, and finally causing the fishing net to be torn.

[0004] A new process is now proposed to solve the above problems. Summary of the invention

[0005] The purpose of the present invention is to solve the above-mentioned problems and provide a production process for a flat tensile fishing net.

[0006] The present invention achieves the above-mentioned purpose through the following technical scheme: a production process of a flat tensile fishing net, comprising: a net body section and an edge section formed by weaving warp and weft, The adjacent warps of the S1 mesh body section and the edge section are staggered to form a number of threading holes; S2 Several different warps are neatly arranged so that their threading holes form a row; The S3 weft thread passes through a number of threading holes in the same row and, after passing through the warp thread at the outermost edge, bypasses the warp thread at the outermost edge to the threading holes in the adjacent row and passes through to form a trimming section; Adjacent warps of the S4 mesh body segment form intersections where the positions of adjacent warps are staggered and interchanged on the basis of the undulating staggered positions of the edge trimming segment.

[0007] Preferably, S1 and S2 can be implemented in a weaving machine by passing the warp threads through a palm frame, causing the warp threads to fluctuate through the movement of the palm frame, and simultaneously pushing the warp threads through the twisted heald to cause the warp threads to be interlaced.

[0008] Preferably, in S3, the weft thread is fixed on the rapier and then passed through the threading hole through the rapier to achieve threading of the weft thread.

[0009] Preferably, the spacing between the warp threads in S1 at the edge segment is one tenth to one fifth of the mesh body segment.

[0010] Preferably, after the weft threads of S3 are threaded, a hot knife is used to cut the weft threads to cause the weft threads to form nodes with a diameter greater than that of the weft threads.

[0011] Compared with the prior art, the beneficial effects of the present invention are as follows: the product utilizes the twisting action of the warp of the net body segment to form a gauze structure, and then does not perform the twisting action on the edge segment to form a plain structure, and utilizes the twisting of the warp of the net body segment so that the warp length at the net body segment is absorbed by the mutual twisting of the twisted wires, while the plain weave of the edge segment is not twisted because the warp does not form a twisted wire. At this time, the overall length of the warp direction of the edge segment will be greater than that of the net body segment, and because the edge segment needs to bypass the edgemost warp to the threading holes in the adjacent row and pass through, the warp of the edge segment is lifted up twice by the same weft, and the two liftings are utilized to shorten the distance of the warp in the straight line direction, and the shortening during the lifting is offset by the shortening during the twisting, so that the overall length of the net body segment and the edge segment in the warp direction is kept consistent, so as to achieve a flat effect, and when the fishing net as a whole remains flat, when subjected to external force, the force will be evenly distributed to each warp, so as to achieve a tensile resistance effect. DETAILED DESCRIPTION

[0012] A production process for a flat tensile fishing net, comprising: forming a net body section and an edge section by weaving warp and weft threads, The adjacent warps of the S1 mesh body section and the edge section are staggered to form a number of threading holes; S2 Several different warps are neatly arranged so that their threading holes form a row; The S3 weft thread passes through a number of threading holes in the same row and, after passing through the warp thread at the outermost edge, bypasses the warp thread at the outermost edge to the threading holes in the adjacent row and passes through to form a trimming section; Adjacent warps of the S4 mesh body segment form intersections where the positions of adjacent warps are staggered and interchanged on the basis of the undulating staggered positions of the edge trimming segment.

[0013] Among them, S1 and S2 can be implemented in a weaving machine by passing the warp through a palm frame, causing the warp to fluctuate through the movement of the palm frame, and at the same time pushing the warp through the twisted heddle to make the warp interlaced. In S3, the weft is fixed on a rapier, and then the rapier is passed through the threading hole to achieve the threading of the weft. In S1, the spacing between the warp at the edge section is one tenth of that of the mesh section.

[0014] The length of the warp threads in the edge section produced by the traditional weaving process is shorter than the length of the warp threads in the body section, resulting in the edge section of the entire fishing net being shorter than the body section in the middle. The middle part of the entire fishing net will bulge due to the pulling of the edges, which seriously affects the quality of the fishing net. However, since the fishing net can still be used after the bulge, the fishing net industry has instinctively ignored this problem, seriously hindering the development of fishing nets.

[0015] Through this process, two weaving processes can be carried out on the same fishing net at the same time, and the combination of the two weaving processes adopts plain weave for the edge section. Since the warp threads will be twisted when the leno structure is used for weaving the fishing net, when it is reflected on the fishing net, there will be a cross in the middle of the mesh of the fishing net, and the warp threads after the cross will form a bulge due to the mutual pressure between the warp threads and the warp threads after the cross. The edge section changes the traditional feature of using the leno structure like the net body and adopts the plain weave. The use of the plain weave will only cause the warp threads to bulge due to the pressure on the weft threads. At this time, for the net body section, since the leno structure has one more warp thread cross than the plain weave structure of the edge section, the whole fishing net is shaped The net is short in the middle and long on both sides. At this time, when the trimming section is trimmed, the weft needs to be inserted into the adjacent threading holes, thereby forming a threading hole formed by the warp in which the same weft needs to pass through twice in the trimming section. When the two wefts pass through the threading holes, the warp can be lifted up again, so that the shortening of the warp in the trimming section caused by the warp being lifted up twice by the same weft and the shortening of the warp in the net body due to the cross and twist of the warp cancel each other out, so that the length of the trimming section and the length of the net body remain the same after the whole fishing net is laid flat, thereby achieving the flatness of the whole fishing net. At this time, when trawling or fishing, no excess resistance will be generated due to the raised net body, which will increase the energy required for dragging.

[0016] After the weft of S3 is threaded, a hot knife is used to cut the weft to cause the weft to form a node with a diameter larger than the weft. Since this product is in the edge section and no twisted wire is formed, its tightness will decrease. Therefore, a hot knife is used to cut the weft. When the hot knife contacts the weft, the heat on the hot knife causes the weft to melt and break. At this time, the broken weft is separated from the hot knife, solidified after the temperature drops, and a node is formed. The diameter of the node is larger than the weft, so that the weft will be stuck in the threading hole, thereby preventing the weft from falling off, thereby achieving the effect of increasing the tightness.

[0017] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be considered exemplary and non-restrictive in all respects, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention.

[0018] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
