Abstract (en)
[origin: EP2463413A1] A fibre comprising a polyolefin composition wherein said composition comprises (per cent by weight): a) from 50% to 85%, of a propylene polymer having an amount of isotactic pentads (mmmm), measured by 13 C-MNR on the fraction insoluble in xylene at 25° C, higher than 97.5 molar %; b) from 5% to 20%, of a copolymer of ethylene and propylene, the copolymer having an amount of recurring units deriving from ethylene ranging from 30 to 50%, and being partially soluble in xylene at 25° C; the polymer fraction soluble in xylene at 25° C having an intrinsic viscosity value ranging from 1.5 to 4 dl/g; and c) from 5% to 30%, of ethylene homopolymer; the sum a) + b) + c) being 100; said composition having a value of melt flow rate ranging from 20 to 150 g/10 min.
