<p>The spunbonded nonwoven (W) has high elastic recovery properties and comp rises 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 thermopl astic polyurethane, and the second polymeric component comprises an elastic propylene-based olefin copolymer, and more particularly an ethylene propylen e copolymer, preferably comprising at least 80wt% of propylene units. Said s punbonded nonwoven (W) can be easily thermal- bonded with polyolefin-based n onwoven layer(s), especially polypropylene-based layer(s), in order to make a composite nonwoven, particularly suitable for the hygienic industry (diape rs,...).</p> |
