Researching of copper filaments availabilities on electromagnetic shielding textiles

In this work, textile materials were developed so as to protect from electromagnetic waves and their usage areas were investigated. For this purpose, Cu/Co core yarns were produced by using copper filaments of two different diameters as core material and cotton as sheath material. Conductive Cu/Co yarns were integrated in to the fabric structure in the weft direction with 5 different weft densities. According to the TS EN 50147-1 standard, the shielding effectiveness of these fabrics was measured in the frequency range 1GHz – 6GHz. The effects of fineness of the core filament, weft density, wave frequency, thickness, basis weight and air permability on the electromagnetic shielding effectiveness of fabrics were investigated. The results were analyzed by using Excel tables, diagrams and SPSS statistic software.
