How is fishing line produced?

Fishing line is also called nylon line. The manufacturing process of nylon line is generally to take the resin and process it into a filament (traditional line) and add other materials such as color to the finished product (four-color line), which has the characteristics of better ductility and elasticity.

When testing nylon threads, first check the flatness, resilience and softness of the thread body by hand. Observe whether the transparency of the thread body is consistent in the light, and then measure the diameter and tension of the thread. If the diameter and tension with the provisions of this label compared to the value of the discrepancy is not large, the diameter of the line does not exceed the positive ten percent, the tension does not exceed the negative ten percent, the line is still acceptable.
