Hereinafter, preferred embodiments of the present invention will be described. However, the embodiments of the present invention can be modified into various other forms, and the scope of the present invention is not limited to the embodiments described below. Further, the embodiments of the present invention are provided to more fully explain the present invention to those skilled in the art.

One embodiment of the present invention comprises the steps of: immersing a base sheet in a hydrogel solution to form a base sheet impregnated with a hydrogel solution; And a step of gelling and drying the base sheet impregnated with the hydrogel solution, wherein the base sheet is impregnated with the hydrogel solution.

Another embodiment of the present invention is a base sheet comprising: a base sheet; And a hydrogel coating layer, wherein the hydrogel coating layer is formed by immersing the base sheet in a hydrogel solution, gelling and drying the hydrogel coating layer, wherein the base sheet is coated with a hydrogel.

For example, the base sheet for a cosmetic pack coated with the hydrogel of the present invention may be prepared by impregnating a base sheet into a hydrogel solution containing a gelled polymer and a polyhydric alcohol, heating and pressing the base sheet using a high temperature and high pressure roller, Gel solution is formed on the base sheet by gelation and drying.

However, since the hydrogel coating is formed on the surface of the fibers forming the base sheet, the hydrogel-coated base sheet for a cosmetic pack then has the ability to contain any other cosmetic composition.

The step of gelling and drying is preferably performed by hot pressing, and for example, high temperature and high pressure rollers can be used. The gelling and drying process can be performed simultaneously by the hot pressing step.

1 shows an exemplary apparatus for producing a base sheet for a cosmetic pack coated with a hydrogel according to the present invention, and Fig. 2 is a cross-sectional view of a base sheet for a cosmetic pack coated with the hydrogel of the present invention. FIG. 3 is a photograph showing one embodiment of a base sheet for a cosmetic pack coated with a hydrogel. FIG. 3 is a photograph of a base sheet for a cosmetic pack in which a conventional hydrogel is not coated.

In order to prepare the base sheet for a cosmetic pack coated with the hydrogel of the present invention, the step of immersing the support, that is, the base sheet in the hydrogel solution is performed.

At this time, the base sheet is preferably a nonwoven fabric produced by pressing at least one fiber selected from the group consisting of natural fibers and synthetic fibers. For example, in order to manufacture the base sheet, the natural fibers or synthetic fibers are discharged to the lower end of the hopper 10, and the fibers are passed through a compression roll 11 to be aligned with a predetermined length and width, Can be manufactured.

Examples of the synthetic fibers include nylon, polypropylene, polyethylene terephthalate, polybutylene terephthalate, polybutadiene, polyamide, polyamide, polyamide, Fibers such as polyethylene, polyvinyl alcohol, polyvinyl chloride, polyacrylonitrile, polyurethane, and polylactic acid may be used, but the present invention is not limited thereto.

In the step of forming the impregnated base sheet, for example, the impregnation tank 12 is filled with the hydrogel solution 30, and the impregnation roll 13 is immersed in the base sheet so that the hydrogel solution can be uniformly impregnated. . ≪ / RTI >

At this time, the hydrogel solution 30 preferably contains a gelated polymer and a polyhydric alcohol, and the weight ratio of the gelated polymer and the polyhydric alcohol is preferably 1: 2 to 1: 8. When the content of the gelling polymer is less than the above-mentioned weight ratio, sufficient strength (stiffness) can not be imparted to the base sheet, and the water holding power and water holding power of the nonwoven fabric are lowered. When the weight ratio is exceeded, dispersion of the gelled polymer and polyhydric alcohol becomes difficult, and the viscosity becomes very high and the fluidity becomes poor. Therefore, it is very difficult to perform the process of uniformly impregnating and dispersing the hydrogel solution in the base sheet .

On the other hand, the gel polymer has a role of regulating the shape and strength of the gel. Examples of the gel polymer include galactomannan, glucomannan, guar gum, locust bean gum, pluronic, agar, algin, carrageenan, And gums, but is not limited thereto.

The polyhydric alcohol imparts the flowability of the hydrogel to the hydrogel so that it adheres to the skin and allows the active ingredients such as cosmetic agents or medicines to penetrate into the skin. The polyhydric alcohol is not particularly limited as long as it is a polyhydric alcohol ordinarily used for producing a hydrogel, and examples thereof include glycerin, ethylene glycol, 1,3-butylene glycol, propylene glycol, dipropylene glycol, sorbitol and xylitol , And more preferably glycerin can be used.

The hydrogel solution may be prepared by dispersing the gelated polymer in a polyhydric alcohol at a temperature of 20 to 30 ° C, for example, so long as the hydrogel is a process for allowing suitable gelation to proceed. can do.

On the other hand, the step of immersing the support in the hydrogel solution in the impregnation bath 12 to form the base sheet impregnated with the hydrogel solution is not particularly limited, but is preferably carried out at 10 to 30 DEG C for 1 to 20 minutes, For example, by immersing the base sheet in a gel solution. For example, the immersion time may be changed according to the degree of hydrophilicity of the base sheet.

Thereafter, the step of gelling and drying the base sheet impregnated with the hydrogel solution is performed, wherein the step of gelling and drying is preferably performed by, for example, heating and pressing.

The hot-pressing is the hydrogel, and the solution is to be carried out hot-pressing by the impregnated base sheet to the heat press roll 14, for example at 100 to 180 ℃ temperature conditions of 20 to heating at a pressure of 60kgf / cm 2 And more preferably at a temperature of 120 to 160 DEG C and a pressure of 30 to 50 kgf / cm < 2 >. At this time, if the temperature condition is less than 100 ° C, the hydrogel impregnated in the base sheet may not be sufficiently dried, and if the temperature condition exceeds 180 ° C, yellowing of the base sheet may occur.

In the step of heating and pressing, it is preferable that the hot press roll 14 is rotated at a rotating speed of 5 to 40 m / min and heat-pressed, but the present invention is not limited thereto.

The hydrogel-coated base sheet 40 for a cosmetic pack prepared through the above-mentioned gelling and drying, that is, a hot pressing step, is subsequently wound on a roller and can be cut into a certain shape as required.

Further, the base sheet for a cosmetic pack coated with the hydrogel may further comprise a step of adding a cosmetic composition such as cosmetic water to the mask pack, the eye patch, the neck patch, the chest patch, the ball patch, the V Line patch, and the like, but it is not limited thereto and can be applied to pack formulations for various purposes.

The base sheet for a cosmetic pack coated with the hydrogel of the present invention obtained by such a process specifically includes a base sheet; And a hydrogel coating layer, wherein the hydrogel coating layer is formed by immersing the base sheet in a hydrogel solution, gelling and drying. That is, in the base sheet for a cosmetic pack coated with the hydrogel of the present invention, the surface of the fibers constituting the base sheet is coated with a hydrogel.

That is, when the gelation and drying processes as described above are performed, a base sheet having hydrogel-coated fibers finally obtained as a base sheet is obtained, and then the flowable cosmetic composition for various cosmetic purposes is impregnated and used as a cosmetic pack .

The details of the production process and the composition of the base sheet for a cosmetic pack coated with the hydrogel are as described above.

Since the base sheet according to the present invention is coated with hydrogel itself, the moisture retention of the base sheet is improved more than that of the general base sheet, and the cosmetic composition such as essence can be contained in the base sheet for a long time. It is possible to provide a base sheet which is excellent in skin moisturizing effect and can restore rough skin to maintain a clean and healthy skin.
