Abstract: 

The article presents the results of the study of indicators that affect the process of formation of complex polypropylene yarns modified by Ag, Cu, Fe and (Ag + Cu) nanoparticles with antimicrobial action. The impact of the above additives on the change of the main physical and mechanical properties of the obtained nanomodified complex polypropylene yarns is shown, in particular, breaking load and change in linear dimensions. The paper also pays attention to the study of the temperature impact on the change of linear dimensions of polypropylene yarns containing nanoparticles. The study demonstrates the possibility of using the proposed nanomodified complex polypropylene yarns for the manufacture of materials and products with antimicrobial properties without losing their physical and mechanical properties. It is also important that the obtained nanomodified polypropylene complex yarns can be further processed into products.

Keywords: 
complex polypropylene yarns, nanomodification, antimicrobial properties, breaking stress, heat setting.
