The aim of the research was to investigate the influence of silver coated yarns incorporated into fabric on the electrical and shielding properties of textile materials designed to ensure protection against the risk of harmful electromagnetic fields as well as thermophysiological comfort in a warm climate. The wearing comfort of conductive textiles is poor due to the chemical nature of synthetic fibres and coatings usually used in their production. In order to solve the problem, natural flax fibres that have good antistatic, hygienic and wearing comfort properties were used as a base for electroconductive textiles. This paper presents the research of these newly developed conductive textile materials. The content of the experimental investigations consisted of determination of the electrical conductivity, electromagnetic interference (EMI) shielding of the materials designed, and an analysis of measurement results. From the results obtained, it can be concluded that not only the amount of conductive additive (in this case –silver) but also the distribution of conductive yarns in woven flax fabric influence the electrical properties, such as electromagnetic wave shielding and electrical conductivity. Correlations between the shielding effectiveness and electrostatic properties are also discussed.

Celem badań było określenie wpływu przędz srebrzonych wprowadzonych do tkaniny na jej właściwości elektryczne i ekranujące. Materiały projektowano dla zapewnienia ochrony przed szkodliwym działaniem fal elektromagnetycznych, a jednocześnie zapewniających termo-fizjologiczny komfort w ciepłym klimacie. Komfort noszenia ubrań wykonanych z włókien syntetycznych jest niski i dlatego do badanych tkanin wybrano włókna lniane, posiadające dobre właściwości antystatyczne i higieniczne zapewniające dobry komfort noszenia. W strukturę lnianych tkanin zostały wprowadzone srebrzone przędze w różnej konfiguracji i gęstości wprowadzenia. Badano czas półzaniku przyłożonego napięcia oraz stopień ekranowania przed falami elektromagnetycznymi emitowanymi przez blisko położone źródło fal elektromagnetycznych. Stwierdzono korelację pomiędzy właściwościami elektrostatycznymi a zdolnością ekranowania. Analizując wyniki stwierdzono, że zdolność ekranowania zależy nie tylko od ilości wprowadzonych przędz przewodzących, ale również od ich konfiguracji w tkaninie.
