Fishing net is divided into gill net, drag net from the function (trawl), purse Seine, build net and apply net. Requires high transparency (partial nylon mesh) and strength, good impact resistance, wear resistance, mesh size stability and softness, appropriate elongation at break (22%~25%). It is made of mono-filament, multi-filament twist (with knotted mesh) or mono-filament braided (Raschel, without knotted mesh), primary heat treatment (fixed nodules), dyeing and secondary heat treatment (fixed mesh size).
Can be used for drift-net fishing, dragnet fishing, fishing, bait fishing and set fishing. Or become cages, cages and other catching supplies manufacturing raw materials.
Nets for fishery production include trawls, purse seines, nets, fixed nets and cages, etc. Trawls and seines are heavy-duty nets used in Marine fisheries. The mesh size is 2.5~5 cm, the diameter of the rope is about 2 mm, the net weighs several tons or even dozens of tons, usually with a pair of tugboats pulling separately to catch fish or by the light boat lure fish concentration and encirclement. The net is a light net for the fishing of rivers and lakes. The mesh size is 1~3 cm, the diameter of the rope is about 0.8 mm, and the mesh weighs several kilograms. Fixed nets and cages are fixed nets for artificial breeding in lakes, reservoirs or bays. The size varies according to the type of fish being raised, and the fish are kept in enclosed water so as not to escape.
The main raw materials of woven fishing nets are 15-36 strands of 210-denier nylon, polyester filament and polyvinyl fiber mono-filament with diameter of 0.8~1.2 mm. The weaving methods are knotting, twisting and warp knitting.
