Abstract: The modification of polypropylene (PP) by nanoadditives (NA) is an effective way to prepare the fibres with advanced properties for textile and technical application. The modification of polypropylene fibres by NA exhibit the change in morphology of modified PP fibres. This paper studies the influence of Cloisite 15A and polyvinyl alcohol on the properties of modified polypropylene/polyvinyl alcohol (PP/PVA) as well as modified polypropylene/polyvinyl alcohol/Cloisite 15A (PP/PVA/CL) fibres. The thermal, mechanical and barrier properties as well as the dyeability of modified PP fibres were evaluated. The results show that the thermal properties of semicrystalline modified PP fibres depend on used additives (PVA and CL) as well as on the conditions of their preparation or treatment. The changed morphology of modified PP fibres provides them with better dyeability.
