【 摘 要 】

Recently, increasing number of studies are performed on protective fabrics containing conductive yarns for electromagnetic shielding purposes. In this paper, several weft knitted fabrics were developed with conductive yarns of the same yarn count and their conductivity and electromagnetic shielding effectiveness (EMSE) were measured. The variations in EMSE as well as reflection, transmission and other physical properties of knitted conductive fabrics were investigated considering conductive yarns and knit structure. It is observed that an increase in the conductive yarns content significantly alters conductivity while all samples demonstrate sufficient EMSE in high frequency bands; Measurements results are presented herein and future research directions are provided.
