For example, the plastic threads can be woven to form a wire mesh structure, which not only maintains the toughness, but also reduces the cost.

However, in the case of the plastic wire mesh, the wire mesh is initially formed by straight wires, and then is woven to form a wire mesh structure with diamond-shaped units, which causes instability of the running direction of the wire mesh, because the wires are not shaped, and thus the wire mesh structure is easily deformed and wrinkled.
