Mask pack sheet fabric and manufacturing method thereof

[0001] The present invention relates to a sheet fabric for a mask pack and a method for manufacturing the same, and more specifically, to a sheet fabric for a mask pack having excellent skin delivery efficiency of a cosmetic product and a method for manufacturing the same.

[0002] Nonwoven fabric is widely used as a material for sheet masks. To enhance the effectiveness of sheet masks, it's essential to enhance the skin delivery efficiency of cosmetics. This can be achieved by controlling the microstructure of the nonwoven fabric.

[0003] However, reproducibly controlling the microstructure of nonwoven fabrics requires highly advanced process technology, and there is a problem that the production cost of mask pack sheet fabrics increases significantly.

[0004] Furthermore, to improve the usability of mask packs, the thickness of the sheet fabric must be reduced. However, thin sheet fabrics are prone to tearing, so the development of sheet fabrics that are sufficiently thin yet possess high tensile strength is required.

[0005] Meanwhile, the background technology described above is technical information that the inventor possessed for the purpose of deriving the present invention or acquired during the process of deriving the present invention, and cannot necessarily be said to be publicly known technology disclosed to the general public prior to the application for the present invention.

[0006] One embodiment of the present invention aims to provide a mask pack sheet fabric and a method for manufacturing the same, which can be easily manufactured without controlling the microstructure of the nonwoven fabric and which has high skin delivery efficiency of cosmetics.

[0007] In addition, one embodiment of the present invention aims to provide a mask pack sheet fabric having a thin thickness to improve usability and high tensile strength, and a method for manufacturing the same.

[0008] The tasks of the present invention are not limited to the tasks mentioned above, and other tasks not mentioned will be clearly understood by those skilled in the art from the description below.

[0010] According to another aspect of the present invention, the thickness of the nonwoven fabric may be 30 to 60 micrometers (μm).

[0011] According to another aspect of the present invention, the tensile strength of the mask pack sheet fabric may be 38 megapascals (MPa) or more.

[0012] According to another aspect of the present invention, there are two or more absorption gaps, and the plurality of absorption gaps can form a predetermined pattern.

[0013] According to another aspect of the present invention, the predetermined pattern may include at least one of a square pattern and a triangular pattern.

[0014] According to another aspect of the present invention, the absorption gap may be linear with a length of 3 to 5 millimeters (mm).

[0015] According to another aspect of the present invention, the absorption gap may have a width of 100 to 200 micrometers.

[0016] According to another aspect of the present invention, for a cosmetic having a viscosity of 500 milliPascal-seconds (mPa-s), the cosmetic absorption amount per minute of the mask pack sheet fabric is square centimeter (cm 2 ) may be more than 0.14 grams (g).

[0017] As a technical means for achieving the above-described technical task, according to another aspect of the present invention, a method for manufacturing a mask pack sheet fabric includes a step of applying a mixed solution of a non-fluorinated water repellent and a thickener to one surface of a nonwoven fabric and a step of drying the nonwoven fabric to which the mixed solution has been applied, and the applying step includes a step of applying the mixed solution in the form of a plurality of islands spaced apart from each other with at least one absorption gap therebetween.

[0018] According to another aspect of the present invention, the method for manufacturing a mask pack sheet fabric may further include a step of preparing the mixed solution before the applying step.

[0019] According to another aspect of the present invention, the step of preparing the mixed solution may include a step of mixing the non-fluorinated water repellent and the thickener in a weight ratio of 1:2 to 1:3.

[0020] According to another aspect of the present invention, the step of applying the mixed solution in the form of the plurality of islands may include the step of applying the mixed solution so that the absorption gaps form a predetermined pattern in plurality.

[0021] According to another aspect of the present invention, the predetermined pattern may include at least one of a square pattern and a triangular pattern.

[0022] According to another aspect of the present invention, the drying step may include a step of heat-treating the nonwoven fabric to which the mixed solution has been applied.

[0023] According to another aspect of the present invention, the heat treatment step may include a step of heat treating the nonwoven fabric to which the mixed solution has been applied at 120 to 180 degrees Celsius (°C) for 20 to 40 seconds.

[0024] According to another aspect of the present invention, the non-fluorine-based water repellent may include at least one of a wax-based material, an acrylate-based material, a urethane-based material, and a silicone-based material.

[0025] According to any one of the above-described problem solving means of the present invention, a mask pack sheet fabric and a method for manufacturing the same include a nonwoven fabric and a non-fluorine-based water-repellent layer provided on one surface of the nonwoven fabric, and the water-repellent layer has at least one absorbent gap penetrating the water-repellent layer, so that a mask pack sheet fabric with high skin delivery efficiency of cosmetics can be easily manufactured by utilizing a water-repellent effect and capillary force without separately controlling the microstructure of the nonwoven fabric or the water-repellent layer.

[0026] In addition, according to any one of the problem solving means of the present invention, the mask pack sheet fabric and the manufacturing method thereof include a non-fluorine-based water-repellent layer provided on one side of the nonwoven fabric, so that evaporation of cosmetics contained in the nonwoven fabric to the outside can be suppressed, and cosmetics preserved in a liquid state can be easily absorbed into the skin.

[0027] Furthermore, according to one of the problem-solving means of the present invention, the mask pack sheet fabric and the method for manufacturing the same include a non-fluorinated water-repellent layer provided on one surface of the nonwoven fabric, so that the tensile strength of the mask pack can be improved due to the high-density coating of the water-repellent layer. Accordingly, even if the nonwoven fabric is thin, damage to the mask pack is suppressed and the risk of breakage is reduced, and the wearing comfort can be further enhanced due to the combined effect of the thin nonwoven fabric thickness and high tensile strength.

[0028] In addition, according to any one of the problem solving means of the present invention, the mask pack sheet fabric and the method for manufacturing the same include a non-fluorine-based water-repellent agent and a non-fluorine-based water-repellent layer manufactured thereby, so that problems arising from the use of fluorine-based raw materials can be solved.

[0029] In addition, according to any one of the problem solving means of the present invention, a mask pack sheet fabric and a manufacturing method thereof include a step of applying a mixed solution of a non-fluorinated water repellent and a thickener to one surface of a nonwoven fabric and a step of drying the nonwoven fabric to which the mixed solution has been applied, and the applying step includes a step of applying the mixed solution in the form of a plurality of islands spaced apart from each other with at least one absorption gap therebetween, so that the structural arrangement of the nonwoven fabric and the water repellent layer as described above can be easily implemented, and a simple method such as printing can be applied to simplify the process. Through this, the productivity of the mask pack sheet fabric having the above-described effect can be improved, and the production cost can be reduced at the same time.

[0030] In addition, according to any one of the problem solving means of the present invention, the mask pack sheet fabric and the method for manufacturing the same include a step of mixing a non-fluorinated water repellent and a thickener in a weight ratio of 1:2 to 1:3, so that when preparing the mixed solution, the viscosity of the mixed solution can be controlled by adjusting the mixing ratio of the thickener within the above-mentioned recommended range, thereby improving the accuracy of printing.

[0031] Furthermore, according to one of the problem-solving means of the present invention, the mask pack sheet fabric and the method for manufacturing the same include a plurality of absorbent gaps forming a predetermined pattern, so that a predetermined pattern can be arranged without any empty space on the entire surface of the water-repellent layer, and the area ratio of the absorbent gaps can be maintained at an appropriate level. Accordingly, the skin delivery efficiency of cosmetics can be maximized.

[0032] In addition, according to one of the problem-solving means of the present invention, the mask pack sheet fabric and the method for manufacturing the same include a plurality of absorbent gaps forming a predetermined pattern including at least one of a square pattern and a triangular pattern, thereby easily implementing a regular pattern and improving the productivity of the mask pack. In particular, when a printing method is used, the formation of a square pattern or a triangular pattern can be easier than other patterns.

[0033] The effects that can be obtained from the present invention are not limited to the effects mentioned above, and other effects not mentioned can be clearly understood by a person having ordinary skill in the art to which the present invention belongs from the description below.

[0046] Meanwhile, the tentative effects that can be expected by the technical features of the present invention that are not specifically mentioned in the specification of the present invention are treated as described in the specification, and the present embodiment is provided to more completely explain the present invention to a person having average knowledge in the art, and the contents shown in the drawings may be expressed exaggeratedly compared to the actual implementation of the invention, and a detailed description of a configuration that is judged to unnecessarily obscure the gist of the present invention is omitted or briefly described.

[0047] The present invention will be described in detail with reference to the attached drawings below.

[0048] Figure 1 is a longitudinal cross-sectional view of a mask pack sheet fabric and a cosmetic according to one embodiment of the present invention.

[0049] Referring to FIG. 1, the mask pack sheet fabric (1000) of the present invention includes a non-woven fabric (1100) and a non-fluorine-based water-repellent layer (1200), and an absorption gap (1210) penetrating the water-repellent layer (1200) is arranged in the water-repellent layer (1200).

[0050] A nonwoven fabric (1100) according to one embodiment of the present invention is a substrate of a sheet fabric (1000) and is configured to come into direct contact with the skin. When the nonwoven fabric (1100) contains a cosmetic, the cosmetic is absorbed into the skin. The specific material of the nonwoven fabric (1100) is not limited as long as it can deliver the cosmetic to the skin, and for example, cotton, rayon, tissue, biocellulose, hydrogel, microfiber, silk, etc. can be used.

[0051] The thickness (t) of the nonwoven fabric (1100) of the present invention may be 30 to 60 micrometers. Accordingly, the thickness of the mask pack sheet fabric (1000) may also be reduced, thereby improving the skin adhesion and wearing comfort of the mask pack sheet fabric (1000).

[0052] If the thickness (t) of the nonwoven fabric (1100) is less than 30 micrometers, it may tear easily even with a small movement, which may cause significant problems in the manufacture and use of the mask pack. If the thickness (t) of the nonwoven fabric (1100) exceeds 60 micrometers, the skin adhesion and wearing comfort of the mask pack manufactured from it may be reduced.

[0053] The water-repellent layer (1200) according to one embodiment of the present invention is a hydrophobic layer having a water-repellent effect that repels moisture, and is preferably provided on the opposite side of the nonwoven fabric (1100) that comes into contact with the skin.

[0054] The water-repellent layer (1200) can improve the tensile strength of the mask pack by coating one side of the nonwoven fabric (1100) at a high density. Accordingly, the mask pack sheet fabric (1000) including the water-repellent layer (1200) of the present invention has the advantage of reducing the risk of damage to the mask pack even if the nonwoven fabric (1100) is thin, and the combined effect of the thickness (t) of the thin nonwoven fabric (1100) and the high tensile strength further enhances the wearing comfort.

[0055] In addition, since the cosmetic (2000) has difficulty penetrating the area of ​​the water-repellent layer (1200) except for the absorption gap (1210) described later, evaporation of the cosmetic (2000) contained in the nonwoven fabric (1100) to the outside can be suppressed. Accordingly, the cosmetic (2000) preserved in a liquid state can be easily absorbed into the skin.

[0056] Meanwhile, the water-repellent layer (1200) of the present invention is a non-fluorine-based water-repellent layer (1200) manufactured with a non-fluorine-based water-repellent agent.

[0057] In the case of fluorine-based water-repellent layers, fluorine-based water-repellents such as C8 water-repellents are included. However, these fluorine-based water-repellents contain PFOA (Perfluoro Octanoic Acid), a non-releasable substance that accumulates in the human blood, which can be harmful to the human body, and there are many cases where their use is restricted.

[0058] On the other hand, the non-fluorine-based water-repellent agent and the non-fluorine-based water-repellent layer (1200) manufactured thereby have the advantage of not having any problems arising from the use of the fluorine-based raw material described above.

[0059] An absorption gap (1210) according to one embodiment of the present invention is arranged in a water-repellent layer (1200) and is configured to penetrate the water-repellent layer (1200) and interconnect the nonwoven fabric (1100) and the outside.

[0060] As illustrated in FIG. 1, when a cosmetic (2000) is introduced to the outer surface of the water-repellent layer (1200), which is the outer surface of the sheet fabric (1000), the cosmetic (2000) is pushed out by the water-repellent effect of the water-repellent layer (1200) and is collected in the absorption gap (1210). The absorption gap (1210) absorbs the collected cosmetic (2000) by capillary force and moves it toward the nonwoven fabric (1100), and the nonwoven fabric (1100) absorbs and holds the cosmetic (2000) introduced through the absorption gap (1210) and, when in contact with the skin, allows the cosmetic (2000) to be absorbed into the skin.

[0061] As described above, the mask pack sheet fabric (1000) delivers the cosmetic (2000) from the outside toward the skin through the combined action of the nonwoven fabric (1100), water-repellent layer (1200), and absorption gap (1210), and as described above, it is very difficult for the cosmetic (2000) to be lost in the opposite direction, so as a result, the skin delivery efficiency of the cosmetic (2000) is significantly improved.

[0062] The width (w) of one absorption gap (1210) of the present invention is preferably 100 to 200 micrometers (μm). If the width (w) of the absorption gap (1210) is less than 100 micrometers, the space for the cosmetic (2000) to pass through may be too narrow, thereby reducing the absorption rate of the cosmetic (2000). If the width (w) of the absorption gap (1210) exceeds 200 micrometers, the capillary force of the absorption gap (1210) may be reduced, thereby reducing the skin delivery efficiency of the cosmetic (2000).

[0063] Meanwhile, the number of absorption gaps (1210) according to one embodiment of the present invention may be two or more. In addition, the plurality of absorption gaps (1210) formed in this manner may form a predetermined pattern.

[0064] FIG. 2 is a drawing for explaining a mask pack sheet fabric including a water-repellent layer having a rectangular pattern of absorbent gaps arranged according to one embodiment of the present invention.

[0065] Referring to FIG. 2, a plurality of absorbent gaps (1210) form a rectangular pattern, and preferably, a square pattern. The water-repellent layer (1200) may be arranged on the nonwoven fabric (1100) in the form of a plurality of square islands spaced apart from each other with the aforementioned absorbent gaps (1210) interposed therebetween.

[0066] The length of one absorption gap (1210) according to one embodiment of the present invention corresponds to the length of one side of the square island described above, and the length may be 3 to 5 millimeters.

[0067] FIG. 3 is a drawing for explaining a mask pack sheet fabric including a water-repellent layer with absorption gaps arranged in a triangular pattern according to another embodiment of the present invention.

[0068] Referring to FIG. 3, a plurality of absorbent gaps (3210) form a triangular pattern, and preferably, an equilateral triangle pattern. The water-repellent layer (1200) may be arranged on the nonwoven fabric (1100) in the form of a plurality of equilateral triangular islands spaced apart from each other with the aforementioned absorbent gaps (3210) interposed therebetween.

[0069] The length of one absorption gap (3210) according to one embodiment of the present invention corresponds to the length of one side of the equilateral triangle island described above, and the length may be 3 to 5 millimeters.

[0070] Since the plurality of absorption gaps (1210, 3210) according to the above-described embodiments are configured in a square or triangular pattern, a certain pattern can be arranged on the entire surface of the water-repellent layer (1200) without any empty space, and the area ratio of the absorption gaps (1210, 3210) can be maintained at an appropriate level.

[0071] If the length of one absorption gap (1210, 3210) is less than 3 millimeters, the absorption gaps (1210, 3210) may be arranged too densely, resulting in an excessively high area ratio, and the tensile strength of the mask pack sheet fabric (1000) may decrease. If the length of one absorption gap (1210, 3210) exceeds 5 millimeters, the area ratio of the absorption gaps (1210, 3210) may become too low, resulting in a decrease in the skin delivery efficiency of the cosmetic (2000).

[0072] Hereinafter, a method for manufacturing the mask pack sheet fabric (1000) of the present invention described above will be described in detail.

[0073] Figure 4 is a flowchart for explaining a method for manufacturing a mask pack sheet fabric according to one embodiment of the present invention.

[0074] Referring to FIG. 4, the method for manufacturing the mask pack sheet fabric (1000) of the present invention includes applying a mixed solution of a non-fluorinated water repellent and a thickener to one surface of a non-woven fabric (1100) (S1000), and then drying the non-woven fabric (1100) to which the mixed solution has been applied (S2000).

[0075] Additionally, prior to the above-described application (S1000) step, a mixed solution of a non-fluorine-based water-repellent agent and a thickener may be prepared in advance.

[0076] The water repellent of the present invention is a non-fluorine-based material having water repellent properties. The specific type thereof is not limited within the scope of not including fluorine-based water repellents. For example, wax-based materials, acrylate-based materials, urethane-based materials, silicone-based materials, etc. can be used as the water repellent.

[0077] The thickener of the present invention is a substance that is mixed with a water-repellent agent to improve the viscosity of the solution, and allows the water-repellent layer (1200) manufactured with the above-described mixed solution to be easily fixed and placed on a nonwoven fabric (1100). The specific type of the thickener of the present invention is not limited within the range in which the viscosity can be increased by mixing with the water-repellent agent. For example, the thickener may include carbomer, cellulose derivative, xanthan gum, silica, acrylate copolymer, alginate, gelatin, etc.

[0078] When mixing the two raw materials described above, the non-fluorinated water repellent and thickener can be mixed in a weight ratio of 1:2 to 1:3.

[0079] If the weight of the thickener is less than twice that of the water repellent, the problem of the applied mixed solution spreading may occur in the application (S1000) step described later, and if the weight of the thickener is more than three times that of the water repellent, the viscosity of the mixed solution becomes excessively high, resulting in too low fluidity and making it difficult to apply the mixed solution easily.

[0080] Below, the step of applying the above-described mixed solution (S1000) is described in detail.

[0081] In applying the mixed solution to one side of the nonwoven fabric (1100) (S1000), the mixed solution is applied in the form of multiple islands spaced apart from each other with at least one absorption gap (1210) between them on the nonwoven fabric (1100), and the above-described absorption gap (1210) may be two or more to form a predetermined pattern.

[0082] As a specific method for applying the mixed solution in the form of the aforementioned multiple islands, printing may be used, for example. More specifically, after a predetermined pattern is determined, the mixed solution may be printed on the nonwoven fabric (1100) along the pattern.

[0083] As a predetermined pattern according to one embodiment of the present invention, a square pattern may be selected. Preferably, as illustrated in FIG. 2, a square pattern may be selected.

[0084] Additionally, as a predetermined pattern according to another embodiment of the present invention, a triangular pattern may be selected. Preferably, as illustrated in FIG. 3, an equilateral triangle pattern may be selected.

[0085] When the mixed solution is applied onto a nonwoven fabric (1100) along a square or triangular pattern according to some of the embodiments described above, a regular pattern can be easily implemented, thereby improving the productivity of the mask pack. In particular, when a printing method is used, there is an advantage in that the formation of a square or triangular pattern is easier than other patterns.

[0086] Meanwhile, when using the printing method, the viscosity of the mixed solution can be controlled by adjusting the mixing ratio of the thickener within the recommended range described above when preparing the mixed solution, thereby improving the accuracy of printing.

[0087] Below, the step of drying (S2000) the nonwoven fabric (1100) to which the mixed solution has been applied is described in detail.

[0088] The nonwoven fabric (1100) to which the mixed solution is applied can be dried through heat treatment.

[0089] The above-described heat treatment can be performed by heat treating the above-described nonwoven fabric (1100) at 120 to 180 degrees Celsius for 20 to 40 seconds.

[0090] If heat treatment is performed at a temperature lower than 120 degrees Celsius, the nonwoven fabric (1100) may not be sufficiently dried. If heat treatment is performed at a temperature higher than 180 degrees Celsius, the fluidity of the applied mixed solution may increase, causing the predetermined pattern to be deformed or disappear, and the physical properties of the nonwoven fabric (1100) may change in an excessively high temperature environment.

[0091] In addition, if the heat treatment is performed for less than 20 seconds, the nonwoven fabric (1100) may not be sufficiently dried, and if it is performed for more than 40 seconds, the productivity of the mask pack sheet fabric (1000) may be reduced.

[0092] The mask pack sheet fabric of the present invention and the method for manufacturing the same include a nonwoven fabric and a non-fluorine-based water-repellent layer provided on one surface of the nonwoven fabric, and since the water-repellent layer has at least one absorbent gap penetrating the water-repellent layer, a mask pack sheet fabric with high skin delivery efficiency of cosmetics can be easily manufactured by utilizing the water-repellent effect and capillary force without separately controlling the microstructure of the nonwoven fabric or the water-repellent layer.

[0093] In particular, even if the viscosity of the cosmetic is low, the cosmetic can flow down through the absorption gap and be absorbed into the non-woven fabric, and the cosmetic stored in the non-woven fabric can be delivered intact to the skin without evaporating, so even low-viscosity cosmetics can be manufactured into mask packs.

[0094] In addition, since the mask pack sheet fabric of the present invention and the method for manufacturing the same include a non-fluorine-based water-repellent layer provided on one side of the non-woven fabric, evaporation of cosmetics contained in the non-woven fabric to the outside can be suppressed, and cosmetics preserved in a liquid state can be easily absorbed into the skin.

[0095] In particular, since it uses a non-fluorine-based water-repellent layer that is harmless to the human body, it can be more stable on the skin than a fluorine-based water-repellent layer, has excellent degradability and may not accumulate in the human body, and is free from various regulations, which may be advantageous in terms of commercialization.

[0096] Furthermore, since the mask pack sheet fabric of the present invention and its manufacturing method include a non-fluorinated water-repellent layer formed on one surface of the nonwoven fabric, the tensile strength of the mask pack can be improved due to the high-density coating of the water-repellent layer. Accordingly, even if the nonwoven fabric is thin, damage to the mask pack is suppressed and the risk of breakage is reduced. In addition, the combined effect of the thin nonwoven fabric thickness and high tensile strength can further enhance the wearing comfort.

[0097] In addition, since the mask pack sheet fabric of the present invention and the method for manufacturing the same include a non-fluorine-based water-repellent agent and a non-fluorine-based water-repellent layer manufactured thereby, problems arising from the use of fluorine-based raw materials can be solved.

[0098] In addition, the mask pack sheet fabric of the present invention and the manufacturing method thereof include a step of applying a mixed solution of a non-fluorinated water repellent and a thickener to one surface of a nonwoven fabric and a step of drying the nonwoven fabric to which the mixed solution has been applied, and the applying step includes a step of applying the mixed solution in the form of a plurality of islands spaced apart from each other with at least one absorption gap therebetween, so that the structural arrangement of the nonwoven fabric and the water repellent layer as described above can be easily implemented, and a simple method such as printing can be applied to simplify the process. Through this, the productivity of the mask pack sheet fabric having the above-described effect can be improved, and the production cost can be reduced at the same time.

[0099] In addition, since the mask pack sheet fabric of the present invention and the method for manufacturing the same include a step of mixing a non-fluorinated water repellent and a thickener in a weight ratio of 1:2 to 1:3, the viscosity of the mixed solution can be controlled by adjusting the mixing ratio of the thickener within the above-described recommended range when preparing the mixed solution, thereby improving the accuracy of printing.

[0100] Furthermore, the mask pack sheet fabric of the present invention and its manufacturing method include a plurality of absorbent gaps forming a predetermined pattern, thereby enabling a predetermined pattern to be arranged without any gaps across the entire surface of the water-repellent layer, and maintaining the area ratio of the absorbent gaps at an appropriate level. Accordingly, the skin delivery efficiency of cosmetics can be maximized.

[0101] In addition, the mask pack sheet fabric of the present invention and the method for manufacturing the same include a plurality of absorbent gaps forming a predetermined pattern including at least one of a square pattern and a triangular pattern, thereby easily implementing a regular pattern and improving the productivity of the mask pack. In particular, when a printing method is used, the formation of a square pattern or a triangular pattern can be easier than other patterns.

[0102] Hereinafter, the present invention will be described in more detail through examples and comparative examples to explain the effects of the above-described mask pack sheet fabric and its manufacturing method.

[0103] However, the following examples are only illustrative of the present invention, and the present invention is not limited to these examples.

[0104] (Manufacturing examples 1 to 30) - Mask pack sheet fabric including a water-repellent layer

[0105] In order to compare and evaluate how much the tensile strength and skin delivery efficiency of cosmetics are improved by the mask pack sheet fabric of the present invention, the following mask pack sheet fabrics were used.

[0106] First, 10 g each of non-fluorinated water repellents such as wax, acrylate, urethane, and silicone were weighed. Each of the four weighed non-fluorinated water repellents was mixed with 20 g of a thickener to prepare four mixed solutions. Additionally, 3 mL (milliliters) of black ink was mixed into each mixed solution to confirm the area to which the mixed solution had been applied.

[0107] When applying the mixed solution manufactured as above to a nonwoven fabric, a square pattern and a triangular pattern were manufactured in which the length of one side was set to 4 mm and the width of the absorption gap was set to 150 μm, and the mixed solution was printed on one side of three types of nonwoven fabrics having a thickness of 30 μm, 40 μm, and 60 μm, respectively, according to the manufactured pattern, to manufacture a total of 24 types of printed materials. In addition, two types of triangular patterns in which the length of one side was the same at 4 mm but the width of the absorption gap was different at 100 μm and 200 μm, respectively, were manufactured, and the mixed solution of the wax, thickener, and ink described above was printed on one side of three types of nonwoven fabrics having a thickness of 30 μm, 40 μm, and 60 μm, respectively, according to the manufactured pattern, to manufacture a total of 6 more types of printed materials.

[0108] Afterwards, the printed matter manufactured as above, i.e., the nonwoven fabrics coated with the mixed solution, were dried by heat treatment at 150°C for 30 seconds.

[0109] Thus, according to each of the cases described above, 24 types of mask pack sheet fabrics (Manufacturing Examples 4 to 6 and 10 to 30) were manufactured with different types of water-repellent agents, different shapes of patterns, and different thicknesses of nonwoven fabrics, but with the same width of the absorption gap of 150 μm. In addition, for the mixed solution of wax and thickener, 6 types of mask pack sheet fabrics (Manufacturing Examples 1 to 3 and 7 to 9) that had a common triangular pattern and different thicknesses of the nonwoven fabric and different widths of the absorption gap were manufactured.

[0110] (Comparative Manufacturing Examples 1-3) - Mask pack sheet fabric (non-woven fabric) that does not include a water-repellent layer

[0111] In order to compare and evaluate how much higher the tensile strength and skin delivery efficiency of cosmetics are of the mask pack sheet fabrics (Manufacturing Examples 1 to 30) including the above-described water-repellent layer compared to the mask pack sheet fabrics (i.e. nonwoven fabrics) not including the water-repellent layer, three types of nonwoven fabrics having thicknesses of 30 μm, 40 μm, and 60 μm, respectively, were prepared.

[0114] (Experimental Example 1) Tensile strength measurement

[0115] To compare the tensile strength of the mask pack sheet fabrics of the above-described manufacturing examples and comparative manufacturing examples, the tensile strength of each was measured. Multiple samples were manufactured and measured for each manufacturing example and comparative manufacturing example, and the average values ​​and standard deviations of the measurement results are shown in [Table 2] and in the graph below.

[0116] Number Sample Name Tensile strength average value (MPa) Tensile strength standard deviation Comparative manufacturing example 1 S30 35.5 13.9 Comparative manufacturing example 2 S40 32.7 11.3 Comparative manufacturing example 3 S60 37.4 11.1 Manufacturing example 1 W_T100_S30 48.8 13.1 Manufacturing example 2 W_T100_S40 45.6 16.2 Manufacturing example 3 W_T100_S60 40.2 14.7 Manufacturing example 4 W_T150_S30 46.6 10.2 Manufacturing example 5 W_T150_S40 46.4 12.3 Manufacturing example 6 W_T150_S60 41.3 13.6 Manufacturing example 7 W_T200_S30 47.2 11.7 Manufacturing example 8W_T200_S4045.19.4 Manufacturing example 9W_T200_S6040.811.2 Manufacturing example 10W_S150_S3049.215.2 Manufacturing example 11W_S150_S4048.214.3 Manufacturing example 12W_S150_S6039.28.7 Manufacturing example 13A_T150_S3051.312.8 Manufacturing example 14A_T150_S4046.611.8 Manufacturing example 15A_T150_S6040.314.1 Manufacturing example 16A_S150_S3046.89.6 Manufacturing example 17A_S150_S4047.211.5 Manufacturing example 18A_S150_S6044.210.8 Manufacturing example 19U_T150_S3047.213.6 Manufacturing example 20U_T150_S4047.311.6 Manufacturing example 21U_T150_S6042.31.6 Manufacturing example 22U_S150_S3050.26.3 Manufacturing example 23U_S150_S4048.913.2 Manufacturing example 24U_S150_S6038.99.9 Manufacturing example 25S_T150_S3044.412.8 Manufacturing example 26S_T150_S4046.711.5 Manufacturing example 27S_T150_S6041.15.9 Manufacturing example 28S_S150_S3046.310.2 Manufacturing example 29S_S150_S4048.212.6 Manufacturing example 30S_S150_S6043.210.6

[0117] [Table 2] shows the measured values ​​for the average value and standard deviation of the tensile strength of each of the manufacturing examples and comparative manufacturing examples described above.

[0118] Figure 5 is a measurement graph of the average tensile strength of mask pack sheet fabrics according to various embodiments and comparative examples of the present invention.

[0119] Specifically, FIG. 5 is a measurement graph of the average value and standard deviation of the tensile strength of each of the above-described manufacturing examples and comparative manufacturing examples, where the average value is depicted as a function value and the standard deviation is depicted as an error bar.

[0120] Referring to [Table 2] and Fig. 5, it can be confirmed that in the case of manufacturing examples, the nonwoven fabric has an average tensile strength of 38 MPa or more even though the thickness is 30 to 60 μm.

[0121] In particular, in the case of sheet fabrics manufactured using a nonwoven fabric having a thickness of 30 μm (Manufacturing Examples 1, 4, 7, 10, 13, 16, 19, 22, 25, and 28), it can be confirmed that a tensile strength of 45 MPa or more, which is required for a mask pack sheet fabric having a thickness of 30 μm, was achieved in all manufacturing examples except Manufacturing Example 25, which showed an average tensile strength of 44.4 MPa.

[0122] On the other hand, in the case of comparative manufacturing examples, it can be confirmed that the average tensile strength is lower at less than 38 MPa even when the thickness of the nonwoven fabric is the same or thicker.

[0123] That is, according to Manufacturing Examples 1, 4, 7, 10, 13, 16, 19, 22, 25 and 28 of the present invention, it can be seen that despite having a thin thickness of 30 μm, it has superior tensile strength compared to a thick nonwoven mask pack sheet fabric of 60 μm. Therefore, it can be seen that the mask pack sheet fabrics of the present invention have excellent wearing comfort due to their thin thickness, and at the same time, tearing of the mask pack fabric can be further suppressed.

[0124] (Experimental Example 2) Measurement of cosmetics absorption rate

[0125] In order to compare the skin delivery efficiency of cosmetics of the mask pack sheet fabrics of the manufacturing examples and comparative manufacturing examples having a nonwoven fabric thickness of 30 μm among the above-described manufacturing examples and comparative manufacturing examples, the absorption rate of each cosmetic was measured. During the measurement, a cosmetic having a viscosity of approximately 500 millipascal-seconds was dropped onto the water-repellent layer of each mask pack sheet fabric, and the absorption amount per unit area and unit time of the mask pack sheet fabric for the cosmetic was measured, i.e., the absorption rate, to obtain the following values.

[0126] Number Sample Name Cosmetic Absorption Rate (g / cm) 2 / min)Comparative manufacturing example 1S300.13Manufacturing example 1W_T100_S300.15Manufacturing example 4W_T150_S300.38Manufacturing example 7W_T200_S300.23Manufacturing example 10W_S150_S300.33Manufacturing example 13A_T150_S300.41Manufacturing example 16A_S150_S300.31Manufacturing example 19U_T150_S300.45Manufacturing example 22U_S150_S300.35Manufacturing example 25S_T150_S300.50Manufacturing example 28S_S150_S300.32

[0127] [Table 3] shows the measured values ​​for the absorption rate of cosmetics of each of the above-described manufacturing examples and comparative manufacturing examples.

[0128] Figure 6 is a measurement graph of the cosmetic absorption rate of mask pack sheet fabric according to various embodiments and comparative examples of the present invention.

[0129] Specifically, Fig. 6 is a measurement graph of the absorption rate of cosmetics of each of the above-described manufacturing examples and comparative manufacturing examples.

[0130] Referring to [Table 3] and Fig. 6, for the cosmetics described above, the absorption rate of the cosmetics of the manufacturing examples is 0.14 g / cm 2 You can see that it is more than / min.

[0131] In particular, for mask pack sheet fabrics with an absorption gap width of 150 μm (manufacturing examples 4, 10, 13, 16, 19, 22, 25 and 28), 0.31 g / cm 2It can be confirmed that it shows a high absorption rate of more than / min.

[0132] On the other hand, in the case of comparative manufacturing example 1, the thickness of the nonwoven fabric is the same at 30 μm, but 0.14 g / cm 2 It can be seen that the absorption rate of cosmetics is lower than / min.

[0133] This is thought to be an effect that occurs when capillary force acts in the absorption gap provided in the non-fluorine-based water-repellent layer of the mask pack sheet fabric of the present invention, effectively introducing the cosmetic product into the non-woven fabric side.

[0134] As described above, through Experimental Examples 1 and 2, it can be confirmed that the mask pack sheet fabric of the present invention and the manufacturing examples according to the manufacturing method thereof have superior tensile strength and skin delivery efficiency of cosmetics compared to the comparative manufacturing examples.

[0135] The foregoing description of the present invention is for illustrative purposes only, and those skilled in the art will readily appreciate that the present invention can be readily modified into other specific forms without altering the technical spirit or essential characteristics of the present invention. Therefore, the embodiments described above should be understood as illustrative in all respects and not restrictive.
