 Full text | Abstract: The modification of PA 6 fibres with macromolecular modifiers in order to improve their sorptive and electric properties was studied. Modifiers consisting of binary, high molecular, semicrystalline copolyamides (from Ă-caprolactam as a major component and 5, 17 and 30 wt.% of nylon salt from adipic acid + diethylenetriamine) and PA 6 homopolyamide were synthesised in the presence of nanoadditive montmorillonite, and the basic characteristics of the modifiers were evaluated. Synthesised modifiers of 10, 20, 30 and 50 wt.% were used for the preparation of blended M/F poly-Ă-caprolactam/modifier fibres and the fibresL properties were evaluated. The electric and sorptive properties of PA 6 fibres modified with modifiers containing montmorillonite were improved; their tensile strength (mainly with lower amount of modifiers) decreased only negligibly. |
