Multilayer nonwoven structure

A nonwoven fabric (NF), comprising a multilayer structure that comprises:

• i) at least one melt blown layer (M) comprising melt blown fibers (MBF) comprising a first propylene polymer (PP1) having:
• a) an amount of 2,1-regiodefects, as determined by 13C-NMR spectroscopic analysis, in the range from 0.0 to 0.1 mol-%;
• and
• b) a melting temperature Tm, determined by differential scanning calorimetry (DSC), in the range from 155 to 170° C.,
• ii) at least one spunbonded layer (S) comprising spunbonded fibers (SBF) comprising a second propylene polymer (PP2) having:
• a) an amount of 2,1-regiodefects, as determined by 13C-NMR spectroscopic analysis, in the range from 0.4 to 1.5 mol-%;
• and
• b) a melting temperature Tm, determined by differential scanning calorimetry (DSC), in the range from 145 to 160° C.
• wherein the melting temperature of the first polypropylene polymer Tm (PP1) is at least 5.0° C. higher than that of the second first polypropylene polymer Tm (PP2).
