| abstract |
A multicomponent fiber comprising at least two polymer components arranged in structured domains, at least one of said polymer components comprising a multipolymer combination of at least two different polyolefin polymers, said polymers being present as a dominant continuous phase of melting temperature lower and at least one non-continuous phase of higher melting temperature dispersed therein, said continuous phase of lower melting temperature forming at least 50 percent by weight of the polymer combination and comprising a polyethylene polymer, and said at least one non-continuous phase of higher melting temperature comprising at least one polypropylene polymer with a melt flow rate of more than 20 g / 10 min or at least one propylene copolymer or terpolymer. |
