In Japan we use a machine to knit from one wire, however in our China plant, they use a machine that can knit 2 to 4 wires simultaneously.
This machine is the same as knitting a sock.
Therefore, this mesh is a little different to the standard mesh. Standard mesh use 2 wires vertically and horizontally but this mesh only use 1 wire, just as our clothes are knitted.
