Description

Technical field:

[0001] The invention relates to a method for testing the physical properties of fishing nets. Background technique

[0002] Netting is one of the important materials in fishery production. Whether it is a variety of nets for marine fishing or freshwater fishing, or cages for sea and freshwater aquaculture, lakes, and fences in reservoirs, mesh sheets are required. The structural type of the mesh can be divided into two types: knotted and knotless. In the knotted mesh, it is divided into slipknot, dead knot, and double dead knot mesh; in the knotless mesh, it is divided into warp knitting, twisting, plain weaving, and twisting mesh. In addition to the knotless twisted mesh, the above-mentioned various knotted and knotless meshes have been widely used in fishing and breeding in my country's fishery production, and the knotless twisted mesh is a newly adopted mesh. Compared with the knotless warp-knitted mesh, the knotless twisted mesh has the advantages of ...
