Effect of stainless steel-containing fabrics on electromagnetic shielding effectiveness

In this paper, stainless steel is selected as the conductive filler to produce stainless steel hybrid yams to make woven fabrics. Using coaxial transmission equipment, the electromagnetic shielding effectiveness (EMSE) of these fabrics is measured. The experimental results show that a denser structure has a higher EMSE. The fabric made from the core yarns has a higher EMSE than that made from the cover yarns and the plied yarns. In addition, the EMSE of the fabric made from different genera of stainless steel has an Optimum EMSE value at different measured frequencies. Analyses of the weave types reveal that the plain weave has a higher EMSE than other weave types.
