The present invention relates to a method for the manufacture of a perforated nonwoven material, whereby a prebonded nonwoven with embossing points is guided to a nonwoven perforation device, needles of a needle roller engage into the prebonded nonwoven and perforate it, and the perforated nonwoven material then undergoes further processing. A ratio is set between the number of needles to the number of embossed points of between 0.15 and 0.25 and a ratio of hole size to embossed point size of between 0.15 and 0.25.
