Methods of manufacturing multifilament yarns of filled high-performance polyethylene (HPPE) fibers that are formed of HPPE filled with a hard component having a Mohs hardness of at least 2.5 are provided. The methods include applying a solvent solution or an aqueous suspension of a polymeric resin to the filled HPPE fibers and thereafter at least partially drying the solvent solution or aqueous suspension to obtain the yarn. The polymeric resin is a homopolymer of ethylene or propylene or is a copolymer of ethylene and/or propylene, and has a density as measured according to ISO1183-2004 in the range from 860 to 970 kg/m, a melting temperature in the range from 40 to 140° C. and a heat of fusion of at least 5 J/g.
