| Abstract | (57) ABSTRACT The spunbonded nonwoven (W) has high elastic recovery properties and comprises a plurality of multi-component fila ments. Each filament, preferably of the sheath/core type, comprises at least a first polymeric component and a second polymeric component. The first polymeric component com prises 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 80 wt % of propy lene units. Said spunbonded nonwoven (W) can be easily thermal-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, . . . ). |
