How is the mesh shape and size of warp-knitted fishing nets flexibly adjusted?

Each user has different requirements for the mesh size of fishing nets. How does the fishing net machine control the mesh count during operation?

This primarily relies on the warp knitting machine's Jacquard system.

This system functions akin to a sophisticated computer, programmatically controlling the movement of each yarn. By pre-programming different jacquard chains or electronic signals, yarns can be precisely directed to loop at specific points and weave at others. This weaves regular mesh patterns—diamonds, squares, hexagons, and more—onto the fabric. It also enables precise control over mesh size and density distribution, achieving instant pattern changes with a single command.
