摘　　要：研究纱线结构和双层织物的排列方式对织物屏蔽效能的影响。采用新型sirospun、sirofil-spun和全聚纺,分别纺制相同线密度的涤纶/不锈钢长丝包芯纱、涤纶/不锈钢长丝包缠纱,以及T/S 80/20混纺纱,并采用上述纱线织制了3种单层平纹机织物,采用法兰同轴法对单层织物、同种纱线双层织物、不同纱线双层织物及不同排列角度双层织物的屏蔽性能测试,结合电磁屏蔽理论对实验结果进行分析。结果表明:所纺纱线密度相同时,包缠纱毛羽最少且强力最高,混纺纱的毛羽最多强力最低;经纬纱均采用包芯纱织制织物时,其屏蔽效能最好;双层织物成45°交叉排列屏蔽效能有所提高。The effect of the structure and the arrangement of the yarns on the shielding effectiveness of the fabric was studied.Polyester/stainless steel filament core yarns,polyester/stainless steel filament yarns and T/S 80/20 blended yarns with the same yarn density were spun by using sirospun,sirofil-spun and complete condensing spinning.Three kinds of monolayer plain weave fabrics were fabricated by the above yarns,and the shielding effectiveness of monolayer fabrics,double-layer fabrics with the same structure yarns,double-layer fabrics with the different structure yarns and double-layer fabrics with different arrangement was tested.The experimental results were analyzed by combining electromagnetic shielding theory.The results showed that,when the density of yarns is same,the hairiness of the sirofil-spun yarn is the least and the strength is the strongest,but the hairiness of the blended yarn is the most and the strength is the lowest.When both the warp and weft yarns are woven with the core yarn,the electromagnetic shielding effect is the best.When double-layer fabrics are arranged with 45°,the electromagnetic shielding property can improve.
