Large scale emissivity measurements vs. temperature of acrylic fabric samples: (a) acrylic coated with SiO2 nanoparticles; (b) acrylic coated with TiO2 nanoparticles; and (c) acrylic uncoated. The emissivity is averaged over 1cm2 area and is measured three times for each temperature. The textiles were heated at the temperature: (o) 45 °C; (Δ) 60 °C; and (□) 80 °C.
