Zusammenfassung: | The present invention relates to a melt spun fiber comprising a propylene polymer composition comprising a terpolymer of propylene with ethylene comonomer units and alpha-olefin comonomer units having from 4 to 12 carbon atoms, wherein the propylene polymer composition has a melt flow rate MFR (230° C., 2.16 kg) of from 10 to 200 g/10 min and a melting temperature of less than 153° C., a spunbonded nonwoven fabric comprising the melt spun fibers, a process for producing said spunbonded nonwoven fabric, an article comprising said melt spun fiber and/or spunbonded nonwoven fabric, and the use of said terpolymer of propylene with ethylene comonomer units and alpha-olefin comonomer units having from 4 to 12 carbon atoms for increasing the spinnability of melt spun fibers and the mechanical properties of spunbonded nonwoven fabrics. |
