Non-woven fabrics have been used for various purposes in various fields, and in recent years, they are expanding to the medical and sports fields. However, the non-woven fabric having various functions and used in various fields has not been widely used in the cosmetic product field due to problems such as skin irritation. On the other hand, the present invention provides a cosmetic pad that can be applied to the cosmetic product field by using a non-woven fabric having excellent physical properties such as minimizing irritation to the skin and following the bending of the human body, convenience, portability, and economy. I want to.

Figure 1 shows a cosmetic pad according to an embodiment of the present invention, Figure 2 shows an enlarged view of the surface of the cosmetic pad according to an embodiment of the present invention.

The cosmetic pad includes a nonwoven fabric; And a cosmetic composition impregnated with the nonwoven fabric, wherein the nonwoven fabric can be formed by physically interlocking fibers of a spiral structure.

The nonwoven fabric may, for example, express crimped fibers having a spiral structure through a crimping process heated with hot water vapor, and adjacent or crossing fibers may be physically interlocked with each other. A cosmetic pad may be provided by impregnating the nonwoven fabric with a cosmetic composition selected according to purposes and uses.

The shape of the cosmetic pad is determined by the shape of the nonwoven fabric, and may have, for example, a rectangular sheet shape, but is not limited thereto, and may be selected without limitation depending on the application.

Particularly, as shown in FIG. 2, some of the spiral structure fibers formed on the nonwoven fabric are formed outside the surface of the nonwoven fabric, and when overlapping the nonwoven fabric, fibers may intersect with each other.

Specifically, there may be helical fibers formed partially outside the surface of the nonwoven fabric by being freed from the surface of the nonwoven fabric. That is, there may be fibers formed outside the surface of the non-woven fabric, and thus, when the non-woven fabric is superimposed, self-adhesiveness, fixation, and the like may be improved due to interlocking of the surface fibers in the overlapping region. For example, fibers formed outside the surface of the nonwoven fabric may be present in the range of 7 to 50, 9 to 45, and 10 to 40 per 1 cm 2 of the nonwoven fabric. If the number of fibers formed outside the surface of the nonwoven fabric per 1 cm 2 of the nonwoven fabric is less than 7, it may be difficult to interlock the fibers when overlapping the nonwoven fabric, and in the case of more than 50, the fibers are interlaced more than necessary Accordingly, a phenomenon occurs in which fibers are fused together, and it is difficult to secure elasticity. However, the present invention is not limited thereto, and the number of fibers per unit nonwoven fabric may be variously selected.

In addition, in the fiber of the spiral structure forming the nonwoven fabric, the average radius of curvature of the circle formed along the spiral axial direction may range from 10 to 250 μm. The average radius of curvature is an index indicating the average size of a circle formed along the axial direction of the helical structure fibers, for example, 20 to 200 μm, 50 to 200 μm, 50 to 160 μm, 60 to 150 μm, or 70 To 130 μm. If the average radius of curvature of the circle formed due to the spiral structure is less than 20 μm, interlocking between fibers is not sufficiently performed, and there is a problem that it is difficult to secure web strength. Conversely, when the average radius of curvature of the circle formed by the spiral structure exceeds 200 μm, the spiral structure is loosely formed, and the number of spiral structure fibers formed outside the surface of the nonwoven fabric decreases, so that the elasticity deteriorates and the nonwoven fabric overlaps. , There is a problem that the intersection between the fibers is difficult. However, the present invention is not limited thereto, and the average radius of curvature of the fiber may be variously selected.

The surface density of the nonwoven fabric may range from 30 to 150 gsm. The surface density means mass per unit area (g/m2), for example, the surface density of the nonwoven fabric is 40 to 140 gsm, 50 to 130 gsm, 50 to 120 gsm, 50 to 110 gsm, 50 to 100 gsm, 50 To 70 gsm or 80 to 100 gsm. If the non-woven fabric has a surface density of less than 30, when using the non-woven fabric, the skin is hardly irritated, so it is difficult to use as a cosmetic pad, and when the non-woven fabric has a surface density of more than 150, irritation to the skin is caused when the non-woven fabric is used. There is a problem that it is too severe to be used as a cosmetic pad. Therefore, in the present invention, the surface density of the non-woven fabric can be easily adjusted within the above range depending on the area where the cosmetic pad is used, and can be produced. For example, in the case of providing a cosmetic pad for use in a relatively sensitive area such as the face and neck, a non-woven fabric having a surface density in the range of 50 to 70 gsm, preferably a surface density in the range of 55 to 65 gsm, can be used. , In the case of providing a cosmetic pad for a relatively insensitive to irritation, a non-woven fabric having a surface density in the range of 80 to 100 gsm, preferably a surface density in the range of 85 to 95 gsm can be used. However, it is not limited thereto, and various surface densities may be applied.

In the cosmetic pad, a non-woven fabric is wound around a part of the user's body, and when winding, the non-woven fabric can be bonded to each other in a contacting area to maintain a wound state. That is, the cosmetic pad can be wound up and used on various body parts of the user according to the purpose and use, and when the nonwoven fabric surface is in contact with each other in the overlapping area of the nonwoven fabric, the fibers formed outward are interlocked and fixed to each other, thereby winding the wound state Can be maintained. For example, the cosmetic pad may be used as a functional pad such as cleansing, whitening and exfoliation. The nonwoven fabric impregnated with the functional composition for performing these functions may be wound and fixed on the fingers, the heel, and the elbow, which are parts of the body, and then fixed and used by overlapping both ends.

In addition, since the non-woven fabrics are arranged and intersected in a predetermined direction in a spiral structure, they may have elasticity in the corresponding direction. For example, if the fibers of the spiral structure of the nonwoven fabric are arranged and intersected with respect to the longitudinal direction (long axis direction) of the nonwoven fabric, the nonwoven fabric may have elasticity in the longitudinal direction (long axis direction). Therefore, when tension is applied to the nonwoven fabric in the longitudinal direction, the fibers of the spiral structure of the nonwoven fabric can be stretched and contracted again.

The non-woven fabric may have a recovery rate after elongation with respect to the longitudinal direction or the width direction measured under JIS L 1913 "General non-woven fabric test method" conditions of 70% or more. Specifically, the recovery rate after stretching can be measured as a value obtained by subtracting the shape strain after the test from the shape before the test when the load is removed immediately after the elongation reaches 50% in a predetermined direction of the cosmetic pad. The recovery rate after elongation can range from, for example, 70% to 100%, 80% to 100%, 85% to 100%, 90% to 100% or 95% to 100%. However, it is not limited thereto, and various recovery rates after stretching may be applied. Since the cosmetic pad has excellent elasticity with respect to a predetermined direction, when the cosmetic pad is wound and used, the cosmetic pad sufficiently follows the shape of the used point, and is appropriately fixed and tightened by friction between overlapping nonwoven fabrics. This is possible.

In the nonwoven fabric, the breaking strength in the longitudinal direction and the width direction may be different. For example, the breaking strength in the longitudinal direction of the nonwoven fabric may range from 5 to 30 N/50 mm, 6 to 25 N/50 mm, or 7 to 20 N/50 mm. When the breaking strength in the longitudinal direction of the nonwoven fabric is less than 5 N/50 mm, the strength of the nonwoven fabric is insufficient to easily break, the brittleness is reduced, and when the breaking strength is more than 30 N/50 mm, the nonwoven fabric is cut by hand. It becomes impossible to do. Alternatively, for example, the breaking strength for the width direction, which is a direction perpendicular to the longitudinal direction of the nonwoven fabric, may range from 0.01 to 1, 0.03 to 0.8, 0.05 to 0.6, or 0.1 to 0.5. That is, since the breaking strength in the width direction is low compared to the length direction of the nonwoven fabric, it is easily cut, and when the nonwoven fabric is manufactured in the form of a tape or strip, it can be easily cut and used by hand as long as desired. However, it is not limited thereto, and various breaking strengths may be applied.

The fibers forming the nonwoven fabric may be arranged to have a uniform density, or may be arranged with different densities. For example, the nonwoven fabric includes a first density region and a second density region, but the first density region and the second density region may be repeatedly arranged in sequence. For example, the first density region and the second density region may be low density regions and high density regions, respectively. The first density region and the second density region may be repeatedly arranged in a lattice structure such as a stripe structure or a mesh structure, but are not limited thereto. According to an embodiment, the density region change of the nonwoven fabric may be formed by varying the density of fibers for each region in a single nonwoven fabric layer or by combining a plurality of nonwoven fabric layers having different density distributions.

When the densities are repeatedly changed, surface bending may be repeatedly formed on the nonwoven fabric. Due to this, the specific surface area of the cosmetic pad can be increased, the amount of the cosmetic composition impregnated in the cosmetic pad can be increased, and when used as a functional pad such as cleansing, whitening, exfoliation, etc. The peeling effect can be additionally implemented within a range that does not damage.

The nonwoven fabric is made of porosity, where the average diameter of the pores can range from 1 to 100 nm. Specifically, since the non-woven fabrics arrange the same or different fibers parallel to each other in a direction orthogonal to each other, the first density region and the second density region described above form a net structure in which repeating arrangements are sequentially repeated. Some pores are formed due to the formed net structure, and the average diameter of the pores is, for example, 1 to 80 nm, 10 to 80 nm, 15 to 70 nm, 20 to 70 nm, 25 to 60 nm, 30 to 60 nm Or 40 to 50 nm. However, the present invention is not limited thereto, and an average diameter of various pores may be applied. The cosmetic pad includes a large number of pores having a diameter within the above range, so that it is easy to impregnate the cosmetic composition, and when using a cosmetic pad in a dry state in the future, the moisture permeability of water may be excellent upon contact with water.

The cosmetic composition impregnated into the non-woven fabric is for user's beauty, makeup, etc., lotion, milk lotion, moisture lotion, nutrition lotion, skin lotion, skin softener, skin toner, astringent, massage cream, nutrition cream, moisture cream, essence , Cleansing cream, cleansing milk, cleansing liquid, face cream, face wash foam, cold cream, skin cream, skin gel, emulsion, and at least one of lotion, but is not limited thereto.

The cosmetic composition may be impregnated into the nonwoven fabric in a liquid state or a dry state. The cosmetic composition may include 30 to 100 parts by weight based on 100 parts by weight of the entire cosmetic pad. For example, when the cosmetic composition is included in a dry state, the cosmetic composition is 30 to 70 parts by weight, 40 to 70 parts by weight, 50 to 70 parts by weight, or 55 to 65 parts by weight based on 100 parts by weight of the cosmetic pad It can be included as a range. In addition, when the cosmetic composition is included in a liquid state, the cosmetic composition is based on 100 parts by weight of the entire cosmetic pad, 60 to 100 parts by weight, 70 to 100 parts by weight, 80 to 100 parts by weight or 85 to 90 parts by weight It can contain. When the cosmetic pad includes the cosmetic composition below the above range, in using the cosmetic pad, it is difficult to sufficiently express the function of the cosmetic composition, and on the other hand, when the cosmetic composition exceeds the above range, the cosmetic pad When winding the application site or applying pressure to use a cosmetic pad, there may be a hassle that the cosmetic composition flows excessively and needs to be wiped off. However, it is not limited thereto, and various impregnation ratios may be applied.

According to an embodiment, the cosmetic pad may be provided in various forms. For example, a single or multiple cosmetic pads may be individually packaged, or a plurality of stacked cosmetic pads may be provided in a retractable form, such as a tissue. In addition, it can be used, for example, in a rolled state. In addition, grooves for cutting the cosmetic pad at predetermined intervals may be formed for each width direction to facilitate cutting or separation of the cosmetic pad.

In one embodiment, the nonwoven fabric may include two or more different composite resins. For example, the nonwoven fabric may include two or more types of composite resins having different heat shrinkage rates. The composite fiber may refer to a latent crimped fiber having an asymmetrical or layered (bimetallic) structure that causes crimping by heating due to a difference in thermal contraction rates of a plurality of resins. The plurality of resins may have different softening or melting points. The plurality of resins are, for example, polyolefin-based resins, acrylic resins, polyvinyl acetal-based resins, polyvinyl chloride-based resins, polypropylin-based resins, polyvinylidene chloride-based resins, styrene-based resins, polyester-based resins, poly It may include one or more of thermoplastic resins such as amide resin, polycarbonate resin, polyparaphenylene benzobisoxazole resin, polyphenylene sulfide resin, polyurethane resin and cellulose resin. In addition, each of these thermoplastic resins may contain other copolymerizable units. Specifically, in the present invention, among the above-mentioned resins, a non-humidity heat-adhesive resin having a softening point or a melting point at which the fibers are not fused by melting or softening even when heat-treated with high-temperature water vapor does not fuse may be included. For example, the composite resin may include one or more of polypropylene-based resin, polyester-based resin, and polyamide-based resin. In particular, aromatic polyester-based resins and polyamide-based resins are preferred from the viewpoint of excellent balance of heat resistance and fiber-forming properties.

In one embodiment, the non-woven fabric of the cosmetic pad may further include non-composite fibers in addition to the composite fibers. As the non-composite fiber, for example, one or more of cellulose-based islands, semi-synthetic fibers, and regenerated fibers may be included in addition to the fibers containing the non-humid heat-adhesive resin or the wet heat-adhesive resin described above. Among these non-composite fibers, recycled fibers such as rayon, semi-synthetic fibers such as acetate, polyolefin fibers such as polypropylene and polyethylene fibers, polyester fibers, and polyamide fibers are preferred. Particularly, from the viewpoint of blendability and the like, composite fibers and fibers of the same type may be used. For example, when the composite fibers are polyester fibers, non-composite fibers may also be polyester fibers. The mass ratio of the composite fiber to the non-composite fiber (composite fiber/non-composite fiber) may be in the range of 80/20 to 100/0, 90/10 to 100/0 or 95/5 to 100/0, for example. By blending non-composite fibers, it is possible to adjust the balance between the strength of the nonwoven fabric and the cutability by hand. However, if the proportion of the composite fiber is too small, when the nonwoven fabric is contracted after being stretched, the non-composite fiber becomes the resistance of the contraction, and thus there is a problem that the securing of recovery stress is lowered.

In one embodiment, the non-woven fabric of the cosmetic pad, the first non-woven layer; And a second nonwoven layer formed on one side or both sides of the first nonwoven layer, and the first nonwoven layer and the second nonwoven layer may have different densities or be formed of different fibers.

For example, the first nonwoven layer and the second nonwoven layer may have different densities. The first nonwoven layer may have a uniform density as a whole, and differently, the second nonwoven layer may be repeatedly arranged in a low density region and a high density region. However, it is not limited thereto.

For example, the first nonwoven layer and the second nonwoven layer may be formed of fibers different from each other. The first nonwoven layer may be a nonwoven layer made using fibers having the same diameter, and differently, the second nonwoven layer may be a nonwoven layer made using two types of fibers having different diameters. The first nonwoven layer is formed of fibers having an average diameter in the range of 0.01 to 0.05 mm, and in the second nonwoven layer, fibers having an average diameter in the range of 0.1 to 0.5 mm and fibers having an average diameter in the range of 1 to 3 mm are periodically crossed. It may include a non-woven fabric is formed. However, it is not limited thereto.

For example, the nonwoven fabric may be a structure formed of two nonwoven fabric layers having different web shapes. Specifically, the first nonwoven layer has relatively thin fibers having an average diameter in the range of 0.01 to 0.05 mm, arranged parallel to each of the major and minor axes of the cosmetic pad so as to have a uniform density over the entire surface of the first nonwoven layer. Can be formed. Since the first nonwoven fabric layer thus manufactured is made of relatively thin fibers, the thickness of the layer is thin compared to the second nonwoven fabric layer, and also, because it is manufactured at a uniform density using fibers having the same diameter, the surface is curved. It can serve as a base for a cosmetic pad in that it may hardly appear. In addition, the first nonwoven layer is formed of a space between fibers due to fibers regularly arranged over the entire surface, whereby water permeability can be improved, and the impregnation of the cosmetic composition can be facilitated. The second nonwoven layer formed on one or both sides of the first nonwoven layer has different diameters by arranging fibers having an average diameter in the range of 0.1 to 0.5 mm and fibers having an average diameter in the range of 1 to 3 mm in parallel to each other in a direction orthogonal to each other. It is possible to form a net structure in which two types of fibers periodically intersect. The two types of fibers having different diameters of the second nonwoven layer may be arranged in parallel with respect to the long axis and the short axis direction of the nonwoven fabric, respectively, to form a periodically intersecting net structure. The second nonwoven fabric layer thus produced has a thicker layer thickness compared to the first nonwoven fabric layer, and a slight surface curvature occurs because it is a net structure in which two fibers having different diameters intersect each other. Due to this, the specific surface area of the cosmetic pad can be increased, the amount of the cosmetic composition impregnated in the cosmetic pad can be increased, and when used as a functional pad such as cleansing, whitening, exfoliation, etc. The peeling effect can be additionally implemented within a range that does not damage.

In one embodiment, the nonwoven fabric may include an impregnated region impregnated with a cosmetic composition and a non-impregnated region adjacent to the impregnated region. The non-impregnated regions can be joined by overlapping fibers with each other. The ratio and position of the impregnated and non-impregnated areas of the nonwoven fabric can be freely adjusted according to the purpose and purpose of the cosmetic pad. For example, the ratio of the impregnated region to the non-impregnated region may range from 2:8 to 9:1, 3:7 to 8:2, and 3:7 to 4:6. However, it is not limited thereto, and various configurations may be applied. In addition, the location of the impregnated region vs. the non-impregnated region forms non-impregnated regions on both sides around the impregnated region, is fixed to the target body part, and the non-impregnated regions on both sides are wound to overlap. If desired, the fibers of the helical structure existing in the non-impregnated region among the nonwoven fabrics in the overlapped region may be interlocked and bonded to each other.

As shown, the cosmetic pad can be made in the form of a roll. The roll-shaped cosmetic pad is manufactured by winding a non-woven fabric, and for example, may be manufactured while being wound in a state where a non-woven fabric is impregnated (dry or wet), or impregnated with a cosmetic material in a wound non-woven fabric. .

The roll-shaped cosmetic pad can be used by unwinding a part of the wound cosmetic pad and cutting it. At this time, grooves for cutting the cosmetic pad may be formed in each width direction at predetermined intervals to facilitate cutting of the cosmetic pad.

Figure 4 shows a method of manufacturing a cosmetic pad according to an embodiment of the present invention.

Method 400, a step of manufacturing a nonwoven fabric (step S410); Crimping the nonwoven fabric (step S420); And it may include a step of impregnating the cosmetic composition (step S430).

The step S410 may be performed through web processes such as a span bond method, a melt blow method, a card method, and an air ray method. Through this, a non-woven fabric of the cosmetic pad as described above can be manufactured. Subsequently, step S420 may be performed by heating the nonwoven fabric of step S410. For example, a non-woven fabric may be treated with high-temperature water vapor, and the non-woven fabric exposed to high-temperature water vapor may exhibit crimping of a spiral structure for each fiber. Subsequently, the cosmetic composition may be impregnated into the nonwoven fabric through step S430 to produce a cosmetic pad.

In one embodiment, the method 400 may further include drying the cosmetic pad after step S430. For producing a cosmetic pad impregnated with a cosmetic composition in a dry state, it is possible to facilitate storage and transportation of the cosmetic pad through this, and in particular, the cosmetic composition in a dry state is easily expressed only by contact with water for ease of use. Can be improved.

Further, in one embodiment, method 400 may further include winding the nonwoven fabric. The winding step may be performed after step S430 to produce a roll-shaped cosmetic pad. Alternatively, the step S420 may be performed after the winding step is performed. Through this, the nonwoven fabric in the form of a roll is disposed in a container in which the cosmetic composition is accommodated, so that impregnation of the cosmetic composition can be facilitated. In this case, after impregnation of the cosmetic composition is completed, it can be used as a cosmetic pad in the form of a roll, or can be used as a cosmetic pad in another form by unwinding the winding.

Hereinafter, the present invention will be described in more detail by examples and experimental examples. However, the following examples and experimental examples are merely illustrative of the present invention, and the contents of the present invention are not limited to the following examples and experimental examples.

Examples 1 to 8: Preparation of cosmetic pads

As shown in Table 1 below, a cosmetic pad was prepared by controlling the size, mass, mass of the nonwoven fabric, mass of the cosmetic composition, surface density of the nonwoven fabric, and the impregnation state of the cosmetic composition. At this time, the cosmetic composition can be freely adjusted as a component of a suitable function according to the purpose and purpose.

Experimental Example 1: Body winding experiment using a cosmetic pad

The result of wearing the cosmetic pad prepared in Example 1 on the user's hand (especially the finger) is shown in FIG. 5.

At this time, the cosmetic pad was wound on the user's finger to be worn, but the number of fingers wound was different. As a result, as shown in the figure, the cosmetic pad can be easily wound up and fixed on the body simply by winding up the cosmetic pad and overlapping both ends, in particular, the shape of the object to be wound, such as varying the number of fingers. Even if the size changes, it is easy to wear.

That is, it can be seen that the cosmetic pad not only has excellent followability according to changes in body parts, but also has excellent retention power in the form of a winding due to the intersection between fibers in the overlapping region.

In FIG. 5, a state in which a cosmetic pad is worn on a user's body is shown as an example, and it is an example, and it can be worn on various body parts such as an elbow and an elbow.

Experimental Example 2: Measurement of recovery rate after elongation of cosmetic pad

For the accuracy of the experiment, the recovery rate after elongation in the longitudinal direction was measured for the cosmetic pads prepared in Examples 1, 3, 5, and 7, which are cosmetic pads in a dry state.

The recovery rate after elongation was calculated by subtracting the shape strain after the experiment from the shape before the experiment when the load was removed immediately after the elongation reached 50% in the long axis direction of the cosmetic pad for each cosmetic pad. The result is as follows.

Recovery rate after kidney (%) Example 1 98 Example 3 97 Example 5 98 Example 7 98

Referring to Table 2, it can be seen that the cosmetic pad has a recovery rate of 97% to 98% after 50% elongation, close to 100%. This means that the cosmetic pad is excellent in elasticity, and in particular, there is almost no shape change even after repeated stretching and contraction.

Experimental Example 3: Cleansing effect experiment of cosmetic pad

6 shows the results of the lipstick and foundation cleansing experiment using the cosmetic pad according to Example 1 impregnated with a cleansing component.

After applying red lipstick (left) and foundation (right) to the body, respectively (see Fig. 6(a)), and after winding the cosmetic pad on two fingers (see Fig. 6(b)), The application area of lipstick and foundation can be wiped off once. As shown in Fig. 6 (c), it can be seen that most of the lipstick and foundation are removed, and when wiped once more, it can be seen that even the little lipstick marks were erased cleanly (Fig. 6 (d). ) Reference).

Experimental Example 4: Comparison experiment of the cleansing effect of a cosmetic pad

7 shows the results of a comparison experiment of a lipstick cleansing effect using a cosmetic pad according to Example 1 impregnated with a cleansing component and a commercially available cleansing tissue.

Red lipstick was applied on the upper and lower sides of the body (see Fig. 7(a)), and the upper lipstick was wiped off with a cosmetic pad, and the lower lipstick was wiped off with a regular cleansing tissue. As a result, as shown in Fig. 7 (b), when using a cosmetic pad, it can be confirmed that the lipstick is completely erased, while using a general cleansing tissue, it can be confirmed that the traces of the lipstick remained fine. have.
