<p>The spunbonded nonwoven web (W) has high elastic recovery properties and comprises a plurality of multi-component filaments. Each filament, preferably of the sheath/core type, comprises at least a first polymeric component and a second polymeric component. The first polymeric component comprises thermoplastic polyurethane, and the second polymeric component comprises an elastic propylene-based olefin copolymer, and more particularly an ethylene propylene copolymer, preferably comprising at least 80wt% of propylene units. Said spunbonded nonwoven web (W) can be easily thermal-bonded with polyolefin-based nonwoven layer(s), especially polypropyfene-based layer(s), in order to make a composite nonwoven, particularly suitable for the hygienic industry (diapers, ...).</p> |
