the extracted slices contain a large amount of water, and can be spun only by drying to remove the water, when the water content of the slices exceeds 0.5%, a large amount of water swallow bubbles can be formed in the melt spinning forming process, the spinning breakage rate is high, and the spinning can not be carried out, when the water content of the slices exceeds 10%, the polymer can be hydrolyzed and chain broken in the melting process due to the existence of water, the polymerization degree is reduced in the drying process, the water is gasified from the interior of the slices due to the action of heat energy, the generated water vapor is continuously discharged by an air extractor, and the water in the slices can be continuously diffused to the surface of the slices to be gasified due to the continuous vaporization of the surface water, so that the drying purpose is achieved. When the melt temperature is too low, the yarn is whitish, the hand feeling is astringent, the drafting broken ends are increased, the melt humidity is too high, and broken yarns are easily generated by drafting. The draft can improve fishing net twine intensity, reduce the extension, increase the cohesion degree between the fishing net twine through the axial tension who adds on the strand silk, make the fibre by original mixed and disorderly, loose molecular chain structure, it is inseparable to stretch the range along fine axial, because macromolecule forms hydrogen bond dipole bond along axial orientation, improved intermolecular gravitation, bear the ability bed clothes of plus tension and improve, thereby the intensity of fishing net twine has been improved, the extension degree is reduced, the internal stress is eliminated. The effect of the temperature and the degree of stretching is to obtain a certain mobility of the macromolecules. The crystallinity, thermal stability and mechanical property of the composite fiber are improved by adding the modified nano montmorillonite.
Compared with the prior art, the invention has the following advantages:
the high-strength corrosion-resistant aging-resistant fishing net thread provided by the invention considers modified polyamide from the aspect of comprehensive application, and has the advantages that the elastic modulus of PA is better than that of PBT and PP from the aspect of dynamics, the specific gravity is high, the settling speed is high, and the like.

Compared with PP, the PP has the main characteristics of high strength and low price, but has poor impact resistance, low temperature resistance and aging resistance. The polyester, the polypropylene and the polyamide are blended, and the advantages of all the components are integrated and mutually supplemented. Polyamides are sensitive to moisture because they contain amide bonds, and in the presence of moisture, the aging process of polyamides is accelerated, they are unstable under the action of light, and they gradually yellow, embrittle and lose mechanical strength. The interaction between the terminal amino group of polyamide and the oxidized product of polyamide can produce various developed pyrrole derivatives, so that the ageing resistance is reduced, the physical property of polyamide is reduced, and the mechanical strength, size stability, weather resistance and the like of nylon are obviously improved after the nylon is enhanced by adopting polyester, polypropylene and modified nano montmorillonite, so that the polyamide material can be widely applied to the fishery.
