Abstract

A multilayer fiber ABA comprising:

A) at least two top layers (layer A) comprisingpropylene copolymer with ethylene having an ethylene derived units content ranging from 3.5 wt % to 6.5 wt %; a melt flow rate according to ISO 1133 (230° C., 2.16 Kg) comprised between from 0.5 g/10 min to 5 g/10 min; a fraction of polymer soluble in xylene at 25° C. ranging from 10 wt % to 17 wt % based on the total weight of said copolymer:B) at least one core layer (layer B) comprising a high density polyethylene having a density ranging from 0.942 g/cm3 to 0.958 g/cm3; and having a melt flow rate (MFR measured at 190° C. 5.0 kg) ranging from 0.3 g/10 min to 5 g/10 min.
