The invention discloses a fuzzing, pilling and ultraviolet-prevention finishing agent and preparation method and application. The finishing agent is prepared by the method comprising the following steps: (1) dissolving titanium alkoxide in an organic solvent, adding the obtained solution into acid aqueous solution and stirring uniformly to obtain a mixture; and (2) adding silicon alkoxide into the mixture obtained in the step (1), and stirring uniformly to obtain transparent solution; or (1) sequentially dissolving acid and silicon alkoxide in water, and stirring uniformly to obtain a mixture; and (2) dissolving titanium alkoxide in an organic solvent, adding the obtained solution into the mixture obtained in the step (1), and stirring uniformly to obtain transparent solution. The finishing agent disclosed by the invention is simple in preparation and short in the finishing process, and meets the requirements of water and energy conservation, low carbon and environmental protection.
