Problems solved by technology

[0003] Modern fishing nets are mainly processed with raw materials such as polyethylene and nylon, which have a longer service life and higher fishing efficiency. However, nylon itself has general mechanical properties and low tensile strength, which leads to the failure of marine fishing nets. Strength and toughness are not suitable for fishing operations in complex seabeds and strong winds and waves; nanocellulose crystals (NCC) are an emerging organic nano-enhancer, which has high strength, low density, biodegradability, and a water-soluble polymer matrix. Good compatibility and other advantages, but pure nanocellulose crystals are mixed with nylon 6 to prepare fishing nets. The compatibility of the two is average, and the processing performance is poor. The strength and toughness of the made fishing nets meet the market demand.

Description

technical field [0001] The invention belongs to the technical field of fishing nets, and in particular relates to a nylon 6 fishing net modified by nano-cellulose crystals. Background technique [0002] Fishing nets are nets for fishing. Ancient people used coarse cloth and hemp as raw materials to make fishing nets by binding and rolling. Although this fishing net is perishable and has poor toughness, its fishing efficiency has been greatly improved. With the development of fishery, the objects of fishing and hunting are not only fish, but also the fishing tools are advancing with the times. The ancients used coarse cloth and hemp as raw materials to make fishing nets by bundling. Although this fishing net is perishable and has poor toughness, its fishing efficiency has been greatly improved. With the development of fishery, the objects of fishing and hunting are not only fish, but also the fishing tools are advancing with the times. [0003] Modern fishing nets are mai...
