The present invention relates to a method for the manufacture of a perforated nonwoven material 1, whereby a prebonded nonwoven 14 with embossing points is guided to a nonwoven perforation device 5, needles 8 of a needle roller 6 engage into the prebonded nonwoven 14 and perforate it, and the perforated nonwoven material 1 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. |
