The invention provides a preparation method and application of a moisture-responsive color-changing fiber. The preparation method of the moisture-responsive color-changing fiber includes the following steps: passing the spinning dope into a coagulation bath containing nano-microspheres, so that the microspheres are attached to the fiber with hygroscopic expansion to form structural color to obtain the moisture-responsive color-changing fiber. When the color-changing fiber encounters water, the fiber absorbs water and expands, which changes the arrangement of nano-microspheres, and the structural color disappears. After the water evaporates, the fiber returns to its original color. The wet-responsive color-changing fiber is prepared by a wet spinning method, which has a simple process and can be industrially produced; the wet-responsive color-changing fiber prepared by this method has firm adhesion of nano-microspheres and strong practicability; the fiber can develop color when it encounters water, and has a fast response , and the response conditions are wide (cold water vapor can make it change color), which can be applied to the fabric to realize the visual monitoring of the environmental humidity.
