Abstract

The invention relates to a fishing net thread. The fishing net thread is prepared from high-strength polyethylene fibers, light calcium carbonate, calcium silicate, MBS resin, tributyltin, an antioxidant 2,6-di-tert-butyl-4-methylphenol through processes of fusion, drawing, spinning and the like. The fishing net thread provided by the invention adopts a simple processing craft. By using high-strength polyethylene as a raw material to process, the price of the fishing net thread is greatly lowered. Moreover, by using high-strength polyethylene as the raw material, the processing method is simple, the fishing net thread is easy to process and mold, and the molded fishing net thread has good tensile strength and wear resistance.

Description

technical field [0001] The invention belongs to the field of fishing gear, and in particular relates to a fishing net line. Background technique [0002] Fishing net line refers to the line with a diameter of less than 4 mm for woven mesh and stitched fishing gear, and is the main material for making fishing nets. The current fishing net line is mainly made of nylon raw materials, but the nylon processing technology is complex, the temperature and humidity requirements are strict, the yield is low, and the cost of nylon is high, and the water absorption rate is also high, which makes the fishing net easy to corrode. Contents of the invention [0003] The object of the present invention is to provide a fishing net line, which improves the processing efficiency of the fishing net line and reduces the cost. [0004] The present invention realizes through following technical scheme: [0005] A fishing net line, consisting of 68-82 parts of high-strength polyethylene fiber, 5...
