What is netting?

As follows:

1. Twisting method: Two groups of yarns are twisted by the machine at the same time and cross each other at the intersection to form a net. Because the yarn at the node of the net is not bent and the net coat is flat, the friction is reduced, but the twisting machine has low efficiency, complicated preparation process and limited transverse mesh, and is only suitable for weaving nets with large mesh.

2. Knot method: It is a traditional method to make fishing nets. The fishing nets in the fishing net factory are woven with warp and weft in the shuttle. The size of the nodule is four times the diameter of the net rope, protruding out of the net plane.

3. Warp-knitting method: The warp-knitted knotless fishing net is flat, wear-resistant, light in weight, stable in structure, high in node strength, and does not deform or loosen after the net is damaged. It can be widely used for special purposes such as marine fishing, freshwater fishing and aquaculture.

pay attention to

Fishing nets can be divided into gill nets, trawls, purse seines, netting and netting. It is required to have high transparency (partial nylon mesh) and strength, good impact resistance and wear resistance. The mesh size of fishing net wire should be stable and flexible, and it can be properly extended (22% ~ 25%) when it breaks.

Trawl and purse seine are heavy-duty nets used for marine fishery fishing. Generally, the mesh size is 2.5 ~ 5 cm, the rope diameter is about 2 mm, and the net weighs several tons or even dozens of tons. Usually a pair of tugboats are used to chase the fish separately or a canoe is used to lure the fish to gather and round up. Cast net is a kind of optical net for fishing in rivers and lakes.
