 Full text | Abstract: This paper describes a study on the development of 2-ply and 3-ply of cotton copper yarns and fabrics for electromagnetic shielding applications. 2-ply and 3-ply of cotton-copper yarns were produced on ring doubling machines and their woven fabrics made on a power loom. The shielding effectiveness of the 2-ply and 3-ply of cotton copper yarn fabrics was measured using the Network Analyser electromagnetic shielding test (ASTM D4935-99) in the frequency range from 20 to 18,000 MHz. The variation in EMSE with the woven fabric structures, ends per cm, picks per cm, cover factor, yarn type, and copper wire diameter are discussed. The results indicate that the woven fabric of higher EMSE proposed can be used for the purpose of EMI shielding, as well as for some electronic and electrical applications. |
