ABSTRACT:
A waved mesh tube including multiple parallel first strings spirally extending in a first direction and multiple parallel second strings spirally extending in a second direction. The second strings are laid on the first strings. The mesh tube has continuous circles of waved bending sections arranged along an axis of the mesh tube. The mesh tube is formed with the bending sections so that the wall of the mesh tube has multiple wave crests and wave troughs adjoining each other. The wave troughs define an inner diameter of the mesh tube, while the wave crests define an outer diameter of the mesh tube. Each of the wave crests and the wave troughs has an acute angle. A difference between the inner diameter and the outer diameter is a thickness of the wall of the mesh tube. The wall of the mesh tube is waved and solid and has higher rigidity.
