Description

Sheet mask for skin care {SHEET MASK FOR SKINCARE}

The present invention relates to a sheet mask for skin care.

In the field of skin care, a sheet type mask (hereinafter, referred to as a "sheet mask") is formed by attaching a sheet made of a specific shape to the skin without needing to hand over the cosmetic material, thereby removing moisture and keratin A cleansing effect, a physiological function recovery effect of the skin, and the like. The sheet mask is provided in various forms capable of covering all or part of the face, hands, feet, collarbone, and the like.

Such a sheet mask has been developed variously according to the design, the effective ingredient of the cosmetic material to be impregnated, the material of the base material, and the like. In recent years, the needs of the customer for the sheet mask material have changed to a preference for a sheet-mask base material made of a naturally occurring component or a new method.

Among them, the base material for a sheet mask is basically required to have properties such as absorption power of a cosmetic, skin adhesion, skin adhesion force during use, and the like. For example, if the thickness of the base material is thin, the skin adhesion can be improved but the absorbing power and adhesion force are lowered. On the contrary, if the thickness of the base material is large, the absorption power may be improved, but the skin adhesion force and adhesive force may be lowered, and the base material may become stiff after the cosmetic material is impregnated.

Various attempts have been made to apply various synthetic fiber nonwoven fabrics such as polypropylene, polyester, polyvinyl alcohol and the like together with the cellulose nonwoven fabric to the substrate to adjust the adhesion and absorption power of the sheet mask. These attempts are mainly based on the use of a multi-layered nonwoven fabric in which nonwoven fabrics having different functionalities are laminated in two or three layers.

However, the multi-layered nonwoven fabric is thicker than the single-layered nonwoven fabric, so that the feeling of use is lowered. Further, complicated processes are required to manufacture and laminate the respective layers.

Japanese Patent Application Laid-Open No. 2008-095223 (Apr. 24, 2008) Korean Patent Publication No. 2009-0014693 (2009.02.11)

The present invention is to provide a sheet mask for skin care, which is capable of exhibiting an excellent absorption force while having excellent skin adhesion and adhesion.

The present invention also provides a method of manufacturing the sheet mask for skin care.

According to the present invention, there is provided a sheet mask for skin care comprising at least one surface of a non-woven fabric crimped.

According to the present invention, the nonwoven fabric may have a crimp formed on at least one side by brushing.

According to the present invention, the nonwoven fabric may be a double-sided crimped fabric.

According to another aspect of the present invention, there is provided a method of manufacturing a nonwoven fabric, comprising: brushing at least one side of a nonwoven fabric to form a crimp; Cutting the crimped nonwoven fabric; And impregnating the cut nonwoven fabric with a cosmetic material.

According to the present invention, in the above manufacturing method, the brushing can be performed on both sides of the nonwoven fabric.

Hereinafter, a sheet mask for skin care according to embodiments of the present invention will be described in detail.

Prior to that, and unless explicitly stated throughout the present specification, the terminology is used merely to refer to a specific embodiment and is not intended to limit the present invention. And, the singular forms used herein include plural forms unless the phrases expressly have the opposite meaning. Also, as used herein, the term " comprises " embodies certain features, areas, integers, steps, operations, elements and / or components, Nor does it exclude the existence or addition of a group.

Meanwhile, according to research conducted by the present inventors, it has been found that a nonwoven fabric having at least one surface crimped or crimped can exhibit an improved absorbing power while exhibiting excellent skin adhesion and adhesion, as compared with general nonwoven fabrics, The sheet mask has been found to be capable of supplying a wide variety of active ingredients to the skin, enhancing skin moisturization and normalizing skin function.

According to one embodiment of the invention, there is provided a sheet mask for skin care comprising at least one surface of which is crimped.

The crimping process is a kind of texturizing, in which the surface of the crimped nonwoven fabric forms a three-dimensional curvature by the curled fibers. The crimped nonwoven fabric has improved flexibility and increased surface friction coefficient compared to general nonwoven fabric by the crimps formed on the surface of the crimped nonwoven fabric, and thus it is possible to provide a sheet mask for skin care having improved skin adhesion and skin adhesion. In particular, although general nonwoven fabrics have a problem of being stiff when they are impregnated with a cosmetic material, the crimped nonwoven fabric may exhibit excellent flexibility even when a cosmetic material is impregnated. Furthermore, the above-mentioned crimped nonwoven fabric has an increased amount of micropores, thereby making it possible to provide a sheet mask for skin care having improved absorption power and cosmetic holding power.

According to an embodiment of the invention, the crimp formed on at least one side of the nonwoven fabric may be formed by brushing the nonwoven fabric.

And, the nonwoven fabric may have a crimp on both surfaces thereof, so that the nonwoven fabric may be preferable for manifesting the above-mentioned effect.

On the other hand, according to another embodiment of the invention,

Brushing at least one side of the nonwoven fabric to form a crimp;

Cutting the crimped nonwoven fabric; And

Impregnating the cut nonwoven fabric with a cosmetic material

A method of manufacturing a sheet mask for skin care comprising the steps of:

That is, the sheet mask produced by the above method includes the above-mentioned crimped nonwoven fabric as a substrate. Here, the formation of the crimp can be performed by brushing the nonwoven fabric.

The brushing is an example of a method of forming a crimp on the surface of a nonwoven fabric by scratching the surface of the nonwoven fabric using a rotating roller provided with a plurality of fine protrusions. The plurality of fine protrusions provided on the rotating roller may have an arbitrary shape (for example, a pointed or sharp end) capable of forming a crimp on the surface thereof by friction with the nonwoven fabric.

As a non-limiting example, the step of brushing at least one side of the nonwoven fabric to form a crimp may be performed using a crimp processing facility (aka "clean air" facility) according to the process shown in FIG.

Referring to FIG. 1, the step of forming the crimp comprises the steps of i) loading a roll of general nonwoven fabric into a clean air facility, ii) loading the nonwoven fabric into a guide, iii) brushing the other side of the nonwoven fabric, iv) brushing the other side of the nonwoven fabric, v) feeding the nonwoven fabric, and vi) rewinding the fed nonwoven fabric .

A crimp is formed on one surface of the nonwoven fabric by the brushing, so that a crimped nonwoven fabric having the above-mentioned characteristics can be obtained. At this time, it is preferable that the brushing is performed on both sides of the nonwoven fabric in order to manifest the above-mentioned effect.

The step of cutting the crimped nonwoven fabric and the step of impregnating the cut nonwoven fabric with the cosmetic may be carried out according to a method known in the art.

For example, the crimped nonwoven fabric may be cut into a shape that can cover the whole face shape, the top / bottom shape of the face, the eyes, the mouth, the cheeks, the forehead, the hand, A skin mask for skin care can be obtained by impregnating it with a cosmetic composition containing an active ingredient or an appropriate skin serum.

The sheet mask according to the present invention has enhanced absorption power, skin adhesion force, and skin adhesion force, thereby sufficiently supplying various active ingredients to the skin, thereby enhancing skin moisturization and normalizing skin function.
