摘　　要：为了研究不同织物结构对织物电磁屏蔽性能的影响,采用导电镀银纤维与不锈钢长丝以及绝缘锦纶长丝为原料,织造了具有电磁屏蔽性能的单双层织物。在织物结构中,以锦纶长丝为经纱,导电纤维作为纬纱,按照一定的比例设计并织造了系列单层和双层织物,并对织物的基本性能及电磁屏蔽性能进行了测试分析。结果表明:双层织物中纬纱为1根锦纶纤维和2根镀银纤维交替织造织物(B1)的电磁屏蔽性能达到最佳,为42.4 dB;纬纱为1根锦纶纤维和2根不锈钢纤维交替织造织物(B4)的电磁屏蔽效果为40.5 dB;电磁屏蔽性能随着导电纤维含量的增加显著提高;在导电纤维含量相同时,镀银纤维织物的电磁屏蔽效果比不锈钢纤维的电磁屏蔽性能好;双层织物的电磁屏蔽性能优于单层织物。In order to study the effect of different fabric structures on the electromagnetic shielding performance of fabrics,conductive silver-plated fibers and stainless steel filaments and insulating nylon filaments were used as raw materials,to weaving the single-layer and double-layer fabric with electromagnetic shielding properties.In the fabric structure,a series of single-layer and double-layer fabrics were designed and woven according to certain ratios with nylon filament yarns as warp yarns and conductive fibers as weft yarns.The basic properties and the electromagnetic shielding performance were tested and analyzed.The results showed that the best electromagnetic shielding performance was 42.4 dB,which was achieved from the double-layer fabric with weft yarns of 1 nylon fiber and 2 silver-plated fibers in alternating weave fabric(B 1).The electromagnetic shielding effect of the fabric(B 4)with a weft of 1 nylon fiber and 2 stainless steel fibers alternately woven was 40.5 dB.The electromagnetic shielding performance increased significantly with the increase in the content of conductive fibers.When the conductive fiber content is the same,the electromagnetic shielding effect of silver-plated fiber fabrics is better than the electromagnetic shielding performance of stainless steel fibers.And the electromagnetic shielding performance of the double-layer fabric is better than that of the single-layer fabric.
