A method of generating pattern via laser cutting process, comprising the step of: 1) Inputting the designed pattern into a computer system; 2) Putting a material beneath a laser beam; 3) Under the control of the computer system, moving the laser beam over the material or moving the material beneath the laser beam in accordance with the pattern input into the computer system so as to cut and generate the pattern with hollow and penetrated shape. On the cloth or fabric material made by this method, the pattern with hollow shape is clear and regular and the fiber threads can't be shed by the laser-sheared edge.
