The invention relates to a rapid large-area preparation method of a bionic photonic crystal structure yarn-producing fabric, which comprises the following steps: S1, preparation of liquid photonic crystal color paste: mixing a nano-microsphere dispersion liquid with a special dispersant, carrying out rotary evaporation to obtain liquid photonic crystals, adding a proper amount of an anti-film-cracking agent and melanin, and uniformly stirring to obtain the liquid photonic crystal color paste; uniformly mixing to obtain liquid photonic crystal color paste with bright color; s2, surface modification of the fabric: coating a special high-molecular polymer on the surface of the fabric, and heating and curing to form a film, so as to obtain the fabric with a special high-molecular layer on the surface; s3, applying the liquid photonic crystal color paste to the surface of the fabric with the special polymer layer through external force shear induced coating, spraying or screen printing; s4, heating the fabric to w
