The present invention relates to a process for the production of a nonwoven fabric. In particular, the present invention relates to the production of a nonwoven fabric having desirable tactile and haptic properties, as well as to the nonwoven fabric itself. The process requires the selection of specific materials and process conditions. The fabric is produced from a masterbatch of isotactic polypropylene homopolymer and a surface-treated calcium carbonate filler.
