摘要：

为探究相同电磁屏蔽织物制备的不同结构与款式服装的屏蔽效能及其影响因素,采用同样材料,制作4种不同款式的电磁辐射防护服,穿在内置喇叭天线的假人上,在半电波暗室,对其屏蔽性能影响因素进行测试分析。结果表明,服装款式、接缝缝隙、结构开口、测试部位、假人模型是否填充吸波材料、电磁场极化方向等都是影响屏蔽效能的因素,尤其是服装款式和接缝缝隙。其中,马甲、大褂、分体服、连体服的胸部电磁屏蔽效能依次提高;当对连体服下腹部接缝缝隙进行导电织物贴片处理后,屏蔽效能大幅度提升;当在假人模型背部填充吸波材料消除谐振腔多次反射后,测试的屏蔽效能亦有所提升。领口、袖口等部位在采用紧口设计时,开口对屏蔽效能的影响并不显著。由于服装结构开口和接缝方向的影响,导致电磁波垂直和水平极化后防护服的屏蔽效能存在差异。

Abstract:

In order to explore the shielding effectiveness and influencing factors of different structures and styles of clothing made of the same electromagnetic shielding fabric,four types of electromagnetic protecting clothing were designed for testing in semi-anechoic chamber by wearing dummy method. The factors affecting the electromagnetic shielding effectiveness were analyzed. The results show that the clothing style, seam gap, test location, dummy model stuffing with absorbing materials, and the polarization direction of electromagnetic field were found as the factors affecting the shielding effectiveness, especially the clothing style and seam gap. The shielding effectiveness went higher in the sequence of vest, coat, split suit to conjoined suit. When conductive fabric patches were applied to the abdominal seam gap of split suits, the shielding effectiveness was greatly improved. After filling the back of the dummy model with an absorbing material to eliminate the multiple electromagnetic reflections in the resonator, the shielding effectiveness of the test was also improved. The effect of opening on shielding effectiveness was proved not significant, when the neckline and cuff were tightly designed. Due to the influence of the seam direction of clothing, there are differences in shielding effectiveness for vertical and horizontal polarization of electromagnetic waves.

Key words: electromagnetic protecting clothing, clothing style, shielding effectiveness, dummy model
