What number of hemp seed line is used to catch 20 Jin of grass carp?

5th-6th, 4th, that's enough. This horse is slippery. If it is not tied properly, it will easily get out of control.

High-strength and high-modulus polyethylene fiber is used as raw material, which is made into thread by cable braiding machine or twisting mechanism, and then colored to make high-strength hemp thread of various colors and specifications. Knitting tightness is generally around 65% (the ratio of fiber volume to linear volume).

The raw materials are also modified by adding a certain amount of high-strength polyester, high-strength nylon and metal wires. Because UHMWPE is a simple macromolecular chain with hydrocarbon structure, without polar groups, with smooth surface and low activity, it can't be dyed with dyes, so it is usually painted with pigments.

Extended data:

Fish bubbles are big and small, far and near, sparse and dense, stop and go. Look at the fish bubbles to decide where to make a nest, including what kind of nest bait to lay. Big bubbles are grass bait, and there are many big bubbles, indicating that there are many grass carp. Although they also spit bubbles, they can be used as bait and no longer have special nests.

While watching the fish bubbles, we should also carefully observe the fish flowers on the water. If there are big fish flowers on the water surface, it means that there is no oxygen at the bottom of the water and it can float.

If there are no bubbles to look at, there are two situations. One is that the fish has left the bottom, and the other is that there is no fish in the water. Fish bubbles are not good in wind and waves, so nests can be arranged according to the type of pond and wind direction.
