BIO-DECOMPOSABLE ROPE NET FOR MAKING A FISHING GROUND, AND THE MANUFACTURING METHOD THEREOF

摘要

PURPOSE: A bio-decomposable rope net for fishing ground and a manufacturing method thereof are provided, which can realize an optimal rope net for the fishing ground. CONSTITUTION: A manufacturing method of a bio-decomposable rope net for fishing ground comprises a pellet drying step(S1) for drying pellets to less than 0.0005% of moisture through vacuum drying; a melting and extruding step(S2) for extruding pellets and melting and extruding pellets; a filament discharge step(S3) for forming the molten resin into the fiber filament; a filament cooling step(S4) for air-cooling the fiber filament; a filament winding step(S5) for winding the fiber filament on a bobbin; and a rope net manufacturing step(S6) for manufacturing the rope net using a bunch of fiber filaments.
