The invention belongs to the technical field of fishing net processing, and particularly relates to a processing method of a fishing net line preventing adhesion and deposition of aquatic plants.
Background
The fishing net thread is a thread with the diameter of less than 4 mm for weaving net sheets and sewing net fishing tools, and is a main material for manufacturing fishing nets. The biomass charcoal is a porous solid particulate matter which is highly aromatic and rich in carbon and is generated by pyrolysis of carbon-rich biomass under the condition of no oxygen or lack of oxygen. It contains a great deal of carbon and plant nutrient substances, has rich pore structures, larger specific surface area and more oxygen-containing active groups on the surface, and is a multifunctional material. The novel biological carbon adsorption fishing net can adsorb heavy metals and organic pollutants in sewage, is not used for research in fishing net line processing at present, can effectively improve the quality of the fishing net when used for processing the fishing net line, but cannot well enhance the strength of the fishing net only by using the biological carbon, and cannot prevent aquatic plants from attaching and depositing when the fishing net is used by being immersed in a water body, so that the service life of the fishing net is shortened.

(5) coating treatment:
suspending the plant growth antibiotics in the air by using a fluidized bed, then adding the mixed powder B obtained in the step (4) to a fluidized bed in a spraying mode, wrapping the antibiotics in a suspension rolling state, and then drying in cold air to obtain the functional filler for later use;
(6) melt spinning:
weighing 70-80 parts of polyethylene, 30-40 parts of the functional filler obtained in the step (5), 6-8 parts of sodium lactate and 75-85 parts of deionized water according to corresponding parts by weight, putting the materials into a spinning tank together for melting, spinning after all the materials are melted, and then obtaining blended yarns for later use after solidification forming, water washing, stretching and drying;
(7) twisting:
and (4) twisting the blended yarns obtained in the step (6) into yarns.
Further, the temperature in the pulverizing machine is controlled to be-20 to-10 ℃ during the pulverizing treatment in the step (1).
Further, the power of the microwave is controlled to be 600-700W during the microwave treatment in the step (2), and the time of the microwave treatment is 4-6 min.
