Embodiment 1

[0029] A method for preparing a fishing net line with strong fishing performance, comprising the steps of:

[0030] (1) Preparation of inner fiber:

[0031] Immerse the acetate fiber and ramie fiber together in the acid solution, then comb them into separate strands, and finally blend and twist the strands to obtain the inner strand fibers for later use;

[0032] (2) Preparation of inner cable fiber paint:

[0033] Weigh the following materials according to the corresponding parts by weight: light calcium carbonate, asbestos powder, polyethylene, natural rubber, modified additives; then blend all the above materials evenly, and heat to a melted state to obtain the inner cable fiber coating agent for later use;

[0034] (3) Preparation of the inner line of the finished fishing net:

[0035] Suspend and draw the inner wire fiber prepared in step (1) in the inner wire mold, then inject the inner wire fiber coating agent prepared in step (2) into the inner wire mold, then heat a...

Description

technical field [0001] The invention belongs to the technical field of fishing net line processing and manufacturing, and in particular relates to a preparation method of a fishing net line with strong fishing performance. Background technique [0002] Modern fishing nets are mainly processed with raw materials such as polyethylene and nylon. 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 cages. ;Because the fishing net made of pure polyethylene material has high waterproof performance, after the fishing net is immersed in water, it will gradually sink, resulting in the reduction of the fishing net's catch water area, reducing the capture efficiency and the amount of fish caught. For example, after being put into the water, it gradually sinks and gathers, and the dispersion of the fishing net in the water is poor, which redu...
