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.
Abstract
In order to study the effect of different fabric structures on the electromagnetic shiel-ding performance of fabrics,conductive silver-plated fibers and stainless steel filaments and insu-lating 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 electromag-netic shielding performance were tested and analyzed.The results showed that the best electro-magnetic 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(B1).The electromagnetic shielding effect of the fabric(B4)with a weft of 1 nylon fiber and 2 stainless steel fibers alternately woven was 40.5 dB.The electromagnetic shielding performance increased sig-nificantly 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.
