In this study, polypropylene (PP) and multi-walled carbon nanotubes (MWCNTs) are used to coat stainless steel (SS) wrapped yarns, the product of which is then fabricated into conductive textiles. Afterwards, the tensile properties, surface resistivity, and electromagnetic shielding effectiveness (EMSE) of conductive textiles are evaluated, thereby determining the influences of the MWCNTs content. The test results show that using MWCNT can effectively improve the mechanical properties of the coated yarns and conductive woven fabrics. In addition, 5 wt % of MWCNT provides the woven fabrics with a lower surface resistivity and higher EMSE. The influences of the lamination angle and number of lamination layers on EMSE are investigated, and the maximum EMSE of −49.89 dB occurs when the lamination angle is 0 °/90 °/0 °.
