Fishing nets have many functions.

Fishing nets are divided into gill nets, trawls, purse seines, netting and laying nets according to their functions. It requires high transparency (partial nylon mesh) and strength, good impact resistance, wear resistance, mesh size stability and softness, and appropriate elongation at break (22%~25%). Twisted by monofilament and multifilament (with mesh)? The fishing net pictures or monofilaments are collected and processed by weaving (Raschel), primary heat treatment (fixing nodules), dyeing and secondary heat treatment (fixing mesh size).
