抗电磁辐射精纺毛织面料的开发及其影响因素

 本文旨在通过两种加工方式研制成抗电磁辐射精纺面料，一种是镀银长丝与羊毛单纱并捻合股织造成并捻织物，一种是镀银长丝直接用作经纬纱与羊毛交织成交织物。由织物的屏蔽效能测试结果可知，并捻织物电磁屏蔽效能在2250-2650MHz波段内优于交织物，最高可达85dB，具有较好的抗电磁辐射效果。另外，经纬密度的变化对织物电磁屏蔽能力也有一定影响，两种织物紧度在78%左右、交织物羊毛与长丝比例为1:2时电磁屏蔽效果较好。其结果对开发高性能抗电磁辐射精纺面料有一定的指导意义。

Development of electromagnetic shielding worsted fabrics and influencing factors

2 kinds of electromagnetic shielding worsted fabrics were developed,one was called doubling and twisting fabric(DTF) made of silver-plated filament and plied wool yarn,and the other was interwoven fabric with silver-plated filament yarn as warp and weft interwoven with wool yarn.Fabric shielding effectiveness tests show DTF to possess better shielding effectiveness than the interwoven fabric at the range of 2 250-2 650 MHz,which is up to 85 dB.Besides,fabric warp and weft density has certain effect on the shielding effectiveness,and better shielding effectiveness was observed when the tightness is 76% for both fabrics and the ratio of wool and silver-plated filament is 1∶2 for the interwoven fabric.These findings have certain directive significance for developing high-performance worsted fabrics against electromagnetic radiation.
