A nonwoven web that contains a plurality of fibers formed from a polyolefm composition is provided. The polyolefin composition contains a rigid propylene polymer that has a relatively high melting temperature and modulus of elasticity, which can provide good strength and durability to the nonwoven web. The polyolefm composition also contains a ductile propylene polymer that has a relatively high melt flow index, which can help achieve relatively fine fibers that minimize the stiffness of the web. In addition to a rigid and ductile polymer, the polyolefin composition also contains a slip additive (e.g., fatty acid derivative). Among other things, such an additive can even further enhance the overall softness of the composition.

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.
