1. A method for manufacturing an artificial leather seat covering comprises:
preparing a base and a covering fabric;
preparing a skin solution containing SiVi represented by Chemical Formula 1, SiH represented by Chemical Formula 2, and a vinyl silicone polymer represented by Chemical Formula 3, wherein x and y are each an integer varying depending on molecular weights;
preparing a binder solution containing the SiVi, the SiH, and the vinyl silicone polymer;
preparing a surface treatment solution containing the SiVi, the SiH, and the vinyl silicone polymer;
applying the skin solution to the base to form a skin layer;
applying the binder solution to one surface of the skin layer to form a binder layer;
bonding the covering fabric to one surface of the binder layer;
removing the base from the skin layer; and
applying the surface treatment solution to one surface of the skin layer to form a surface treatment layer,
wherein the skin solution is prepared by mixing the SiVi, the SiH, and the vinyl silicone polymer at a first ratio, the binder solution is prepared by mixing the SiVi, the SiH, and the vinyl silicone polymer at a second ratio, and the surface treatment solution is prepared by mixing the SiVi, the SiH, and the vinyl silicone polymer at a third ratio, wherein the first, second, and third ratios are different from one another, and
wherein, in the preparing of the skin solution, the SiVi and the SiH are mixed at a weight ratio of 1:1.5 to 5,
