A Research on the Use of Copper Core Yarns in Electromagnetic Shielding Application
Project no. 1208 · Status: Kapanmış · 2017
Summary
With technological progress, electrical and electronic devices become irreplaceable items of our life with numerous facilities they provide. Usage of these devices, both facilitate our life and bring along environmental pollution. Because, while they are working, they emit electromagnetic waves to their surroundings. Electromagnetic waves are known to have harmful effects for both sensitive electronic equipment and also for human health. 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 as core material and cotton as sheath material. Production of the yarns was carried out on a ring spinning frame. Copper monofilaments of 0.05 mm and 0.07 mm were used as core materials. All core yarns are produced with Ne 8 yarn count. Conductive Cu/Co yarns were integrated in to the 3/1 twill woven fabric structure in the weft direction with 5 different weft densities (8, 13, 18, 23 and 28 per cm). 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. According to the TS EN 50147-1 standard, the shielding effectiveness of these fabrics was measured in the frequency range 1GHz – 6GHz. The results were analyzed by using Excel tables, diagrams and SPSS statistic software.
