Fishing diamond-type screen tricot knitting net sheet repairing method

Abstract

A repairing method of a fishery raschel netting with diamond meshes relates to the repairing of fishery raschel netting and provides a repairing method of fishery raschel netting with diamond meshes. The technical proposal of the invention comprises netting clipping and suturing. The invention is characterized in that a hole of a raschel netting with diamond meshes is tailored into a rectangular and the bar end of the clipping boundary of the hole adopts a melting treatment; a piece of netting which is tailored into a rectangular with the latitudinal and longitudinal mesh number at least two more respectively than that of the rectangular hole and with the same specification is selected and the bar end of the clipping boundary of the rectangular netting adopts the melting treatment; a nylon fishing net line or a polyethylene net line with the same diameter as that of the bar end of the repairing netting is taken as a suture; the rectangular netting used for repairing is piled up at the position of the rectangular hole and the meshes of the repairing netting which outnumber the rectangular hole along the latitudinal and longitudinal direction on number are aligned with the meshes around the hole; the suture is rooted at a mesh connecting place which is three meshes away from the hole and is used for equal mesh suturing; and a net knot used for repairing the netting adopts a double dead knot. The method is suitable for the repairing of the fishery raschel netting with diamond meshes.

Description

Technical field: [0001] The invention relates to a method for repairing warp-knitted nets for fishing. Background technique [0002] Mesh is one of the important materials in fishery production. Whether it is a variety of fishing gear used for sea and freshwater fishing, or cages for sea and freshwater aquaculture, and fences in lakes, mesh sheets are required. Mesh can be divided into two types: knotless mesh and knotted mesh from the structural type. Knotless mesh is divided into warp knitted mesh, twisted mesh, flat woven mesh, twisted mesh; knotted mesh is divided into slipknot mesh, dead knot mesh and deformed mesh; Warp knitted mesh and dead knot mesh have been used in fishery production. Since the successful research and development of warp-knitted mesh in my country around 1985, compared with dead-knotted mesh, warp-knitted mesh with diamond mesh has stable mesh size, compact mesh structure, light weight, low cost, and mesh can be edited. It is very small, the sha...

Problems solved by technology

However, there is still a lack of suitable repair methods for the damage of the diamond mesh warp knitted mesh.

When the rhomboid warp-knitted mesh is partially damaged in the production of cage culture, the farmers are at a loss what to do, so they have to replace the whole top of the cage mesh. The use has brought difficulties, and it has become one of the main factors restricting the popularization and use of warp knitted mesh in net gear.
