In one embodiment, a substrate comprising fibers derived from natural components; And it provides a sheet for a mask pack comprising a seaweed extract impregnated between the fiber strands of the substrate.

The mask pack sheet is a base material for being made into a final mask pack by subsequently impregnating with a skin composition or water. The mask pack sheet may exhibit excellent water absorbency for the skin composition or water by including an algae extract deeply impregnated between the substrate including the fiber and the fiber strand of the substrate.

In addition, the mask pack sheet by itself includes the seaweed extract, it is possible to minimize the amount of the skin composition to be used additionally. In addition, since the algae extract is contained deep between the fiber strands of the substrate has the advantage that the algae extract is not lost during the process of manufacturing the mask pack using the sheet for the mask pack.

In addition, when the mask pack to which the mask pack sheet is applied is used for the skin, high adsorption to skin may be realized through the algae extract. In addition, the seaweed extract can implement the effect of maintaining the composition or water for a long time absorbed into the skin.

When the seaweed extract is applied to the fiber base in a general manner, it is difficult to embed the seaweed extract deeply between the fiber strands of the base. However, the mask pack sheet according to an embodiment may have a structure in which the algae extract is deeply impregnated between the fibers of the base by being manufactured according to a manufacturing method described below using a specific substrate and a specific seaweed extract.

Specifically, the substrate includes fibers derived from natural ingredients. As used herein, the term 'natural component-derived fiber' refers to a natural fiber or a fiber processed and / or modified. For example, the natural component-derived fiber may include one selected from the group consisting of cotton fibers, silk fibers, cellulose fibers, regenerated cellulose fibers, and combinations thereof.

As used herein, the term "regenerated" fiber refers to a fiber in which a polymer material is made uniform by dissolution or melting, and this is formed into a fiber.

The regenerated cellulose fiber refers to a fiber made from cellulose regenerated by precipitating cellulose or a derivative thereof in a predetermined solution or an additive compound.

For example, the regenerated cellulose fiber is a cellulose fiber regenerated using xanthogenate (viscose); Cellulose fibers regenerated using copper ammonia or a complex thereof; Cellulose fibers regenerated using acetic acid or acetate esters; Cellulose fibers regenerated using alkaline cellulose; And combinations thereof.

More specifically, the regenerated cellulose fiber may include one selected from the group consisting of viscose rayon fiber, copper ammonium rayon fiber, acetate cellulose fiber, triacetate cellulose fiber, and combinations thereof.

As such, the substrate may be impregnated with a sufficient content of the algae extract by including the aforementioned fiber derived from natural components. In addition, compared to chemically synthesized fibers, it is possible to provide a soft touch to the skin and to secure an advantage of minimizing contact of chemical components.

The substrate may be a nonwoven fabric produced using natural component derived fibers having a predetermined length and thickness. When the substrate is in the form of a non-woven nonwoven, the natural component derived fibers may have a three dimensional network structure in the substrate. This is advantageous to secure a space between the fibers as compared to the woven form, as a result, the seaweed extract can be impregnated with a high content of the substrate.

The length of the natural component-derived fiber is not particularly limited, but may be, for example, about 20 mm to about 60 mm. In addition, the fiber thickness of the natural component-derived fiber is not particularly limited, for example, may be about 0.5dtex to about 2.0dtex.

The length and thickness of the fiber derived from the natural component satisfy the above-mentioned range, thereby ensuring an appropriate space in the substrate by the entangled structure thereof, thereby improving the impregnation of the seaweed extract.

The seaweed extract may be in the form of a gel. In this case, it is advantageous to be impregnated in the base material, and high viscosity can be imparted to the surface of the mask pack sheet.

The algae extract is not particularly limited in kind, but may refer to components extracted from red algae, green algae, brown algae and the like.

Specifically, the algae extract is a wood starfish, stone starfish, seaweed, thorny radish, silk grass, edible, stone, Jinuari, ox radish, walnut, haeincho, spino island, kotoni, walnut, seaweed, seaweed, seaweed, persimmon, mabanban It may include a component extracted from seaweed including one selected from the group consisting of, gompi, antagonist, chlorella, jangmal, half moon, cheontae, auditory, green and combinations thereof.

Specifically, the seaweed extract may include alginate (alginate) extracted from seaweeds such as seaweed, kelp, butts.

The mask pack sheet may have a content of the seaweed extract in the total weight of about 5% by weight or more, for example, about 5% by weight to about 45% by weight, for example, about 26% by weight to about 35% by weight, For example, about 16% to about 32% by weight. The mask pack sheet may have a high content of seaweed extract by having a structure in which the seaweed extract is deeply interposed between the fiber strands of the substrate.

Substrate comprising the natural component-derived fiber and the seaweed extract impregnated therein, as a combination thereof, can greatly increase the absorption performance of the moisture or skin composition.

The mask pack sheet is applied to the skin, it may be advantageous to secure a certain degree of transparency in order to continuously check the state of the skin after attaching it. The mask pack sheet according to an embodiment may ensure a high light transmittance through the substrate and a high content of seaweed extracts impregnated therein. For example, the light transmittance of the sheet for the mask pack may be about 50% or more, for example, about 50% to 65%, for example, about 55% to about 65%.

The mask pack sheet may implement excellent tensile properties through the extract of seaweeds in the form of a gel (gel) impregnated between the substrate and the fiber strand of the substrate.

Specifically, the tensile strength of the sheet for the mask pack may be about 45 N / 5cm to about 100 N / 5cm, for example, may be about 45 N / 5cm to about 70 N / 5cm. The tensile strength means strength when the mask pack sheet is torn in one direction.

Since the seaweed extract is in the form of a gel and at the same time deeply impregnated between the fiber strands of the substrate, it acts as a kind of binder to improve the tensile strength of the mask pack sheet, and to secure an appropriate tensile elongation. have. Through the tensile strength in the above-described range, the workability and handling of the subsequent process of the mask pack sheet can be improved.

The mask pack sheet may have a thickness of about 0.1 mm to about 0.5 mm. In addition, the mask pack sheet may have a basis weight of about 30g / ㎡ to about 100 g / ㎡.

When the thickness and basis weight of the sheet for the mask pack satisfies the above range, the mask pack to which the mask pack is applied may contain a sufficient amount of water or a composition for skin, and at the same time ensure excellent lightness and conformity.

As described above, the mask pack sheet includes a natural ingredient-derived fiber and an algae gel impregnated between strands of the fiber, thereby ensuring hypoallergenicity, excellent moisturizing property, and soft adhesion to skin. can do.

In addition, since the mask pack sheet itself includes a seaweed extract in the form of a gel, the absorbency may be improved to reduce the amount of impregnating a skin composition such as an essence. In addition, since the gel-like seaweed extract acts as a volatilization prevention film, the skin composition such as moisture or essence can be maintained in the skin for a long time even after the mask pack is applied to the skin.

In another embodiment, a method of manufacturing the mask pack sheet is provided. Specifically, the method for producing a sheet for the mask pack comprises the steps of preparing a substrate comprising a natural component derived fiber; Dip coating the seaweed extract on the substrate; And pressure coating the seaweed extract on the substrate.

The mask pack sheet having the above-described advantages can be manufactured through the manufacturing method. Details of the natural component-derived fiber, the base material, and the algae extract are as described above.

The method comprises the step of preparing a substrate comprising a fiber derived from natural ingredients. Specifically, the substrate may be prepared by processing the fiber derived from the natural component in a water jet spunlace process.

More specifically, the substrate comprises the steps of preparing a fiber derived from the natural component having a predetermined length; Dispersing said natural component derived fiber; And it may comprise the step of producing the non-woven fabric using the natural component-derived fiber.

The natural component derived fibers can be cut, for example, to have a length of about 20 mm to about 60 mm.

The wet process is not particularly limited as long as it is a method for producing a fiber having a predetermined length in the form of a nonwoven fabric, for example, a cylindrical paper machine, a fourdrinier machine, an inclined wire device, etc. wire, spunlace machine, or the like.

In one embodiment, the nonwoven can be manufactured by a spunlace process. Specifically, the natural component-derived fibers cut to a predetermined length may be made of a nonwoven fabric having a fiber intertwined structure using a water jet sprayed at a predetermined pressure.

The water jet is water sprayed at a predetermined pressure. As the water jet is sprayed onto the dispersed fibers, the fibers are entangled with each other, so that the water jet may be made of a nonwoven fabric. For example, the water jet may be sprayed at a pressure of about 80 MPa to about 120 MPa, for example about 80 MPa to about 100 MPa, for example about 80 MPa to about 95 MPa.

The manufacturing method includes a step of dip coating the seaweed extract on the substrate. The dip coating is a method of dipping and coating the substrate in an immersion solution containing the seaweed extract.

The immersion solution is a viscosity-adjusted composition so that the seaweed extract can be moved and disposed to the inside of the substrate. Specifically, the immersion solution may include about 5% to about 80% by weight of the seaweed extract.

The method includes the step of pressure coating the seaweed extract on the substrate. The seaweed extract may be disposed between the fiber strands that are deeply impregnated inside the substrate to form the substrate by applying both the dip coating and the pressure coating.

The dip coating and pressure coating are simultaneously; Or may be performed sequentially.

The pressure coating may be performed by pressing both surfaces of the substrate. Specifically, the pressure coating may be performed under pressure conditions of about 70 MPa to about 90 MPa. By performing the pressure coating under the above-described pressure conditions, it is possible to prevent the substrate from being damaged and to allow the algae extract to penetrate deep inside the substrate.

The manufacturing method may further comprise the step of preparing the seaweed extract. The algae extract, as described above, wormwood, stone fern, seaweed, spiny radish, silk grass, scabbard, stone, Jinuari, ox radish, walnut, Haeincho, spino island, kotoni, stalk, seaweed, kelp, 톳, Ingredients extracted from algae including one selected from the group consisting of Ecklonia cava, Maban, Gompi, Contrast, Chlorella, Jangjang, Half Moon, Cheongtae, Hearing, Sea Green and combinations thereof.

As described above, the mask pack sheet manufacturing method, unlike the conventional coating of the algae gel by a simple surface deposition method, so that the algae extract soaked into the fiber of the substrate by applying both the dip coating and pressure coating method. can do. As a result, the mask pack sheet may contain a high algae extract.

In addition, the seaweed extract of the mask pack sheet is in the form of a gel (gel) exhibiting a high viscosity, even in the form of such a high viscosity, deeply impregnated in the substrate, foreign matters or whitening during use of the mask pack to which the mask pack sheet is applied It is possible to prevent the development and to secure excellent adhesion to the skin of the mask pack.
