Abstract
In this work, possibilities for producing textile materials with copper core cotton yarns for the purpose of electromagnetic shielding were studied. Cu/Co core yarns were produced by using copper filaments as core material with two different diameters (0.05 and 0.07mm) and cotton as sheath material. All core yarns are produced in Ne 8 yarn count. Conductive Cu/Co yarns were integrated in to 3/1 twill woven fabric structure in the weft direction with 5 different weft densities (8, 13, 18, 23 and 28 per cm). According to the TS EN 50147-1 standard, the shielding effectiveness of these fabrics was measured in the frequency range 1 GHz - 6 GHz. The results have shown that EMSE of fabrics can be tailored by changing the weft density, core filament fineness and wave frequency parameters.
