Analysis of the electrical and mechanical properties of hybrid yarns designated for protection against electromagnetic field

Popis výsledku v původním jazyce

Hybrid yarns with enhanced electric conductivity were prepared during the research. They were designated for development of a hybrid electromagnetic shielding fabrics. These yarns were composed of polypropylene and extremely thin steel fibers in staple form. Yarns were produced in two special linear densities and they contain different conductive component content (1 ? 60 %). Electrical properties of these yarns and chosen mechanical properties depending on yarn structure and conductive component content were studied. It was found that dependence of electric resistance on clamping length is highly nonlinear for yarns containing the conductive staple metal fibers. The main aim of this paper is investigation and validation of a simple mechanistic model describing this dependence. Characteristic parameter of this model is so called specific resistivity a. This factor is used for expressing the influence of content of metal fibers on the yarns conductivity or resistivity changes. Moreover,
