Abstract—Near infrared (NIR) shielding textiles have attracted a great interest recently for energy saving and human comfort. On the other hand, far infrared (FIR) rays with a longer wavelength of 6-15 μm can enhance blood microcirculation and metabolism. Therefore, FIR emission fabric also shows commercial value. Self-assembly Cs

3 nanosheets and converted into FIR radiation for human blood circulation. Compared with current infrared shielding textiles using solid-liquid phase change materials (PCMs), Cs
0.32WO
3 coated textiles possess better shielding property and longer service life, no leakage and FIR emission. The excellent NIR absorber Cs

3 nanosheets were successfully synthesized in this study. The coated fabrics were tested for NIR shielding property, FIR emissivity and laundering durability. Cs
0.32WO
3 coated textiles with excellent infrared shielding performance of lowering the temperature of about 4.5 °C, good FIR emissivity of increasing fabric surface temperature to 64 °C, and washing durability were comprehensively maintained.
