Electromagnetic shielding characterization of conductive woven fabrics produced with silver-containing yarns

This paper presents a study of the electromagnetic shielding characterization of woven fabrics, produced with two different types of conductive yarns, namely silver-containing (Ag/PA/Co) core yarns and silver-containing (Ag/PA-Co) blended yarns. The effect of various yarn and fabric properties, such as yarn count, core filament count, blend ratio, weft density, electrical resistivity, yarn type and wave frequency, on the electromagnetic shielding effectiveness was investigated. The results have shown that the shielding effectiveness can be tailored by changing the yarn and fabric parameters and also there are significant differences between the electromagnetic shielding characteristics and performances of the fabrics produced with different yarn groups. Such fabrics are future promising for both daily and professional uses, since they combine high shielding effectiveness performance and the comfort properties of conventional fabrics.
