The invention discloses a high-elasticity wrinkle-resistant fabric and a preparation method thereof, belonging to the technical field of textile fabric preparation. The method comprises the following steps: synthesizing a polyurethane resin in one step from a chain extender, a compounding agent, a polyol and a diisocyanate in a twin-screw extruder, crushing and dissolving to obtain a polyurethane solution; adding the polyurethane solution, sodium hydroxide solution, bromine gas and aluminum chloride into a reaction kettle for heating reaction for 4-8 hours, adding benzene into the reaction kettle, cooling to 0-5°C for reaction for 15-20 hours, adding a finishing agent, stirring and separating, and taking the organic phase A to obtain a mixed solution; performing electrostatic spinning on the mixed solution, stretching and curing to obtain the high-elasticity wrinkle-resistant fabric; benzene rings are connected with ureido functional groups of hard segments through chemical bonds, reducing sliding and relative displacement of hard segments of fibers, improving the node firmness of hard segments, thereby enhancing fiber elasticity; introducing benzene rings increases fiber thickness and improves wrinkle resistance.
