Problems solved by technology

[0002] Modern fishing nets are mainly processed with polyethylene, nylon and other raw materials. Among them, polyethylene fishing nets are made of polyethylene materials through melt plasticization, spinning, and ply twisting. They are used for marine trawls, purse seines, and wind-resistant sea nets. Boxes, etc., have a longer service life and higher fishing efficiency, but the mechanical properties of polyethylene itself are average. With the continuous improvement of fishing net manufacturing technology, the strength and wear resistance of fishing nets have gradually been improved. The aging performance is poor, and the use environment of the fishing net is relatively complicated, which determines that the aging of the fishing net will seriously affect the performance of the fishing net. The existing technology usually improves the weather resistance of the fishing net by adding anti-aging agents, but it will correspondingly affect the performance of the fishing net. Physical properties, therefore, further research on the weather resistance of fishing nets is required
