The incorporation of passive radiative cooling structures into personal thermal management techniques can effectively protect people from the impacts of increasingly harsh global climate change.Using silicon oxide (SiO2) and polyamide 6 (PA6) as raw materials,passive radiative cooling fibers were prepared by industrial melt-spinning methods and were further woven into fabrics by hand loom.The inorganic particle dispersion,fiber mechanical properties and indoor and outdoor radiative cooling properties of fabrics were tested.The results showed that the inorganic particles were uniformly dispersed in the fibers.When the SiO2 particle size was 4 μm and its mass ratio was 5%,the performance was optimal.The measurement of simulating cooling effect at night revealed that the SiO2-added fabrics had a cooling effect of 4℃ compared with the fabrics without SiO2.
