Paper Title:
Electromagnetic Shielding Effectiveness and Manufacture Technique of Functional Bamboo Charcoal/Metal Composite Woven
  Abstract

In order to fabricate textiles with electromagnetic shielding effectiveness (EMSE) and far infrared emissivity, we fabricated bamboo charcoal/metal (BC/M) composite wrapped yarns with metal wires (stainless steel wires or copper wires) as the core yarn and bamboo charcoal textured yarn as the wrapped yarns using a rotor twister machine. The optimum manufacture parameters included: the speed of the rotor twister was 8000 rpm and the wrapped amounts of the BC/M composite wrapped yarns were 4 turns/cm. The BC/M composite wrapped yarns were made into the BC/M composite woven fabrics using a loom machine. Moreover, we tested the BC/M composite woven fabrics in EMSE and then changed the lamination angles. When the lamination amount was 6, laminated angles were 0°/45°/90°/-45°/0°/45°, 0°/ 90°/0°/ 90°/0°/ 90°, and the frequencies of the incident waves were between 1.83 and 3 GHz, the EMSE of the BC/M composite woven fabrics reached 50 to 60 dB which was satisfactory.
