Concentrates of copolyamides consisting of copolyamide (?-caprolactam + nylon salt of adipic acid and diethylenetriamine and nylon salt of 1-(2-aminoethyl) piperazine and adipic acid) and the nanoadditive Bentonite were prepared, characterised and used for the preparation of blend polypropylene (PP) fbres. PP fbres modifed with 4, 8 and 12 wt.% of the three types of concentrates prepared were spun without a compatibiliser by the standard melting process and drawn at three drawing ratios. Mechanical properties of the modifed PP fbres, i.e. tenacity and Young´s modulus, are better mainly at lower amounts of each concentrate and at higher drawing ratios. Te electric properties of the modifed PP fbres are positively infuenced by all three concentrates. Te higher their amount in the modifed PP fbres, the better the electrostatic properties. Te sorptive properties of the modifed PP fbres, i.e. the sorption of water vapour and disperse dyestufs, are much better in comparison with non modifed PP fbres.
