Electromagnetic Shielding Effectiveness and Manufacture Technique of Functional Metal Composite Knitted Fabrics

Abstract

In order to fabricate fabrics with electromagnetic shielding effectiveness (EMSE) and other function, we fabricated Crisscross-section polyester /antibacterial nylon / stainless steel wires (CSP/AN/SSW) composite yarns with stainless wires as core yarn, antibacterial nylon and crisscross-section polyester as inner and out wrapped yarns, respectively. Knitted fabrics were fabricated with the metal composite yarns with wrap amount of 8 turns/cm on a circular knitted machine. Furthermore, the EMSE of the metal composite fabrics were evaluated by changing the lamination amounts and lamination angles. The results show that when the lamination amount was four, lamination angles were 0°/45°/90°/-45°, the EMSE of the fabrics reached to-10--20 dB in the frequency range of 300 KHz to 3 GHz.

Research on Carbon Foam Image Segmentation Based on Deep Learning

“…Due to their low density, great electrical conductivity, ease of modification, and high chemical stability, carbon materials have increasingly replaced metal materials in the area of electromagnetic shielding during the last several decades. Among carbon materials, carbon foam has a tunable three-dimensional network cell structure: a material with low weight, a broad absorption frequency, and specific structural and functional properties [1][2][3][4]; therefore, it has been highly desired by researchers. The majority of research has shown that differences in the cell structure of carbon foam [5] have a large influence on its electromagnetic shielding performance.…”
