Abstract
In this study, the effect of design parameters of metal composite woven fabric on electromagnetic shieldingeffectiveness (EMSE), electrical resistivity and antibacterial activity properties were investigated. For this purpose, metal compositeyarn including insulated copper, stainless steel, silver wires and silver coated polyamide (Shieldex) were plied with 100% cotton spunyarns by two-for-one twisting technique. Eight different composite fabrics were produced in hand loom with different metalcomposite yarn densities. 100% cotton fabric was also produced as control sample. EMSE, surface resistivity, antibacterial activityand circular bending rigidity tests were applied to the samples. As a result, all fabrics including metal composite yarns showed EMSEup to 53 dB levels. Stainless steel, silver wires and silver coated polyamide have 106 times lower surface resistivity than copper andcontrol samples. Antibacterial activity of copper and silver samples were investigated for control purposes. Finally, antibacterialactivity was not observed in both samples due to the insulation of copper and non-ionizable silver coating.
