Radiative cooling fabrics and products

A radiative cooling fabric, comprising a flexible substrate layer and a functional layer stacked in order;

• wherein the functional layer comprises a first functional layer, a thickness of the first functional layer is in a range of 10 μm to 200 μm, the first functional layer comprises a first functional resin and a first functional filler dispersed in the first functional resin, and the first functional filler comprises a first filler and a second filler;
• wherein a mass fraction of the first functional filler in the first functional layer is in a range of 1% to 20%, an emissivity of the radiative cooling fabric in a wavelength of 7 μm to 14 μm is not less than 80%, a reflectivity of the radiative cooling fabric in a wavelength of 300 nm to 2500 nm is not less than 80%, an average value of warp recovery angles of the radiative cooling fabric is greater than or equal to 95°, and an average value of the weft recovery angles of the radiative cooling fabric is greater than or equal to 91°;
• the radiative cooling fabric further comprises a waterproof layer located on a side of the flexible substrate layer away from the functional layer, a thickness of the waterproof layer is in a range of 1 μm to 20 μm, a material of the waterproof layer is selected from acrylic resin, polyurethane resin, epoxy resin, or a combination thereof, and a transmittance of the waterproof layer is greater than or equal to 80% in a wavelength of 400 nm to 700 nm.
