The present invention discloses a manufacturing process of a radiation phase-change cooling fiber bionic to silver ant hair, comprising the following steps: S1, design of spinneret holes: scaling spinneret holes in a certain proportion to produce fibers with different diameters; S2, selection of phase-change capsules: using silica as the shell material for phase-change capsules, which can withstand melt extrusion temperature and pressure, and adopting n-eicosane with a phase-change temperature of 35°C as the core material; S3, mixing: mixing light-scattering micro-nano particles and polymer raw materials in a certain proportion, and feeding the mixture into a twin-screw extruder for mixing, extrusion and pelletizing; S4, melt spinning process: using a screw extruder for melt spinning. For a single melt extruder in the present invention, when the area of a single spinneret hole is 1.7304 mm², the output reaches 0.193 g/min per hole (or hole count × 94 m/min), with the capacity for large-scale production; the reflectance in the solar wavelength range (400–700 nm) reaches 87%.
