Abstract (en)
The spunbonded nonwoven (W) has high elastic recovery properties and comprises a plurality of multicomponent filaments. Each multicomponent filament, preferably of the sheath/core type, comprises a first polymeric component (P) and a second polymeric component (P'). The first polymeric component (P) comprises an elastic propylene-based olefin copolymer, and the second polymeric component (P') comprises an elastic propylene-based olefin and has a melt flow rate MFR2 that is higher than the melt flow rate MFR1 of the first polymeric component. Said elastic spunbonded nonwoven (W) can be easily bonded with polyolefin-based nonwoven layer(s), especially polypropylene-based layer(s), in order to make a composite nonwoven, particularly suitable for the hygienic industry (diapers, ...).
