Abstract: This contribution is devoted to the preparation of copolyamides from E-caprolactam, adipic acid, and diethylenetriamine and to the establishment of some basic characteristics of copolyamides. Experimental data confirm the possibility to synthesize copolyamides with relative molecular mass high enough to prepare blended fibres. Blended fibres from 90-50 mass % of PA 6 and 10-50 mass % of copolyamide were prepared and the hydrophilicity, elastic, electrical, and mechanical properties of PA 6 fibres were studied. Besides mechanical properties all other properties of blended fibres are better in comparison with those of unmodified PA 6 fibres.
