It is a fiber spun from polyethylene with a molecular weight of 1 million to 5 million. The fishing nets in the existing technology use ultra-high molecular weight polyethylene fiber material, which can increase the use of stronger tensile force.

However, the material of the fishing net has strong toughness. When it breaks, there is a lack of protection, which can easily cause damage to the inspectors. At the same time, the tensile fracture problem cannot be visually checked. Utility Model Content
