Assessment of Electrical Characteristics of Conductive Woven Fabrics
Electroconductive textiles can not be considered as homogenous structures, because fabrics consist of conductive and nonconductive yarns, interlaced to each other. Such distribution of yarns results in anisotropic current distribution, when voltage is applied. The aim of investigations was investigate current and temperature distributions in conductive textiles, which can be used in many applications, such as protective textiles, e textiles, heating textiles etc. It was found that the Ohm's law is valid for such type of textiles and temperature increases increasing voltage applied. The amount of current passing through the conductive yarn depends mainly on the conductivity of it. The length of conductive yarn also influences values of current and temperature. It was concluded that current passes through yarns with silver coated filaments more homogeneously than in yarns with metal fibres, because of continuous coating. Also it was noticed, that there exists a maximum voltage which can be fed to the conductive yarns, without damaging it.
