【Irregular punching caused by ill-posed needle-board configuration marks undesirable surface patterns on nonwoven fabrics that diminishes the value of commodities of the nonwoven fabrics. The research shows methods for minimizing the undesirable patterns through optimizing needle-board configuration (the zigzag method, the hexagonal method, the random method and the X-Y Square method). The virtual nonwoven fabric images generated by each method was compared according to so called 'uniformity index' for their performance.】
