Abstract :In this study, electromagnetic shielding and solar properties of woven fabrics which were produced barium titanate/polyester bicomponent yarns were investigated. 1, 2 and 3% additive ratios of barium titanate and three different fabric structures insert ignore into journalissuearticles values(1/1 plain, sateen and special weave); were used in the experiments. The effect of additive ratio and the fabric structure on electromagnetic shielding properties were evaluated. Electromagnetic Shielding Effectiveness insert ignore into journalissuearticles values(EMSE); of the woven fabrics was determined according to the ASTM D4935-10 standard by using coaxial transmission line measurement technique in the frequency range of 15–3000 MHz. The fabric with the highest content of the barium titanate insert ignore into journalissuearticles values(3%); and special weave showed the highest shielding effectiveness, reaching 13.96 dB at 15 MHz. The solar properties were measured according to EN14500 using a UV/VIS/NIR spectrophotometer and results were calculated according to EN 410 standard. The reflectance values of barium titanate added polyester fabrics increased and the transmittance values decreased.
