Crease: Partially folded on the mesh surface, forming an irreversible impression.
Holes: There are multiple warps or wefts on the surface of the mesh.
Corrosion: corrosion on the surface of the mesh,
Rust spots: green, brown, or discolored spots appear on the mesh surface.
Broken wire: The meridian or weft thread on the surface of the mesh must be disconnected.
Mosquito mouth: The metal wire makes a circle, twists, and empties the mesh surface.
Top buckle: poor warp joints, top out of the net surface.
Weft reduction: Local cubic meters of weft are bent and the mesh is deformed.
Filament: Two or more wires are woven together in parallel.
Jumping wire (jump shuttle): warp or weft cross stitching error.
Loose wire: Loose displacement of individual warp or weft.
Miscellaneous materials weave in: foreign material weaves in the net.
Cloud weaving: Overlapping wefts or soft and hard inhomogeneities create irregular cloud-like patterns.
Drum kits: The network surface bulges out.
