In order to make conductive woven fabrics with electromagnetic shielding effectiveness (EMSE) and flameretardance, polysufonamide (PSA)/stainless steel (SS) core yarn are used as the weft yarns and PSA yarns are used as thewarp yarns. The conductive woven fabrics are denoted as SS-60, SS-80, SS-100, SS-120, and SS-140 according to the twistcounts of the core yarn, and evaluated in terms of mechanical properties, flame retardance, surface resistivity. The test resultsshow that the best twist of the core yarn is 120 turns/10 cm. SS-60 has the maximum burnt length, while SS-140 has theminimum burnt length. Moreover, the surface resistivity of the PSA/SS woven fabrics is proportional to the twist counts, andthe surface resistivity along the warp direction is higher than that along the weft direction. Changing the fabric laminationangle can form a complete shielding network, and the EMSE is significantly increased. For SS-80, SS-100, and SS-120,when they are composed of 4-6 layers with lamination angles of 0 o/45 o/90 o/-45 o/0 o/45 o and 0 o/90 o/0 o/90 o/0 o/90 o, theEMSE is above 40 dB and the shielding effect is above 99.99 % against the incident waves at 2000-3000 MHz. Specifically,SS-120 has the maximum EMSE of 64 dB against incident waves at 2844 MHz.
