A polymer filament comprising a polyolefin composition which comprises at least 10% by weight of one or more copolymer(s) (I) of propylene with one or more comonomers selected from ethylene, C-C&#x3b1;-olefins and their combinations, said copolymer or copolymers (I) having MFR from 0.5 to 10 g/10 min. and containing units deriving from the said comonomers in a total amount of from 0.5 to 25% by weight with respect to the total amount of all momoner units in the copolymer, provided that, in the absence of comonomer units deriving from C-C&#x3b1;-olefins, the amount of comonomer units deriving from ethylene or C-C&#x3b1;-olefins or their combinations is at least 2.5% by weight.

Polymer filament

A polymer filament or fiber comprising a polyethylene material (I) having the following features:

Polyethylene fiber or filament

A polymer filament comprising a polyolefin composition which comprises (percentages by weight): A) 5%-95% of a propylene homopolymer; and B) 5-95% of a butene-1 homopolymer or copolymer having a flexural modulus of 80 MPa or higher.
