Abstract: The present invention relates to a method of manufacturing a modeling mask pack using various fabric sheets. In particular, by using various fabric sheets (nonwoven fabric, rayon, cotton, tencel, microfiber, mesh, etc.) as modeling fabrics, elasticity and sealing effect are maximized, thereby providing improved effects for skin firmness and shrinkage with respect to physical pressure. In particular, a modeling paste, obtained by mixing powder with a liquid, is adsorbed and applied to a fabric sheet with one or two rollers, wherein the liquid is obtained by mixing water and an alcohol with an appropriate amount of an adhesive component, polyvinyl acetate or polyvinyl alcohol, wherein the alcohol may be ethanol or methanol; and the powder is obtained by combining at least three kinds of polysaccharides, such as sodium alginate, potassium alginate, calcium sulfate, tetrapotassium pyrophosphate, glucose, and dextrin, and combining all or part of cellulose gum, silica, diatomite, and kaolin. Subsequently, the fabric sheet is standardized to a certain form of formulation, and in order to dry and fixate the standardized form, the fabric sheet having the powder adsorbed thereto is passed through a high-temperature tunnel, such that the form of formulation can be retained. Furthermore, the fabric sheet thus produced in the formulation form is processed into a mask pack sheet by being hole-punched to form a face shape, and then soaked in an essence and sealed.
