A Study on the Anti-electromagnetic Radiation Performance of Fabric with Silver-plated Fibers

摘要

In order to study on the anti-electromagnetic radiation performance of fabrics with silver-plated fibers, five sets of samples with polyester DTY and silver-plated nylon filament were manufactured for the experiment. The anti-electromagnetic radiation property of fabrics was tested with Flange coaxial method. The influence of different silver-plated fiber contents on the anti-electromagnetic radiation performance of fabrics was analyzed in this paper. The experimental results show that when silver-plated fibers are distributed by a network, anti-electromagnetic radiation performance of fabrics is better than that the silver-plated fibers are distributed only along the warp in fabrics. Meanwhile, the anti-electromagnetic radiation performance of fabrics improves as the increasing of the silver-plated fibers content. The anti-electromagnetic radiation performance of fabrics increases slowly when silver-plated fibers content is from 40% to 80%. The shielding effectiveness of fabrics for 10MHz～1000MHz electromagnetic waves increases not obviously when silver-plated fibers content is more than 80%, but that for 3000MHz is still rising. The anti-electromagnetic radiation performance of fabrics is the best when silver-plated fibers content reaches to 100%.
