Description

{COSMETIC SHEET}

The present invention relates to a foamable cosmetic sheet which can be used as a pack, a bathing agent, a shower gel, and the like, more specifically, a foamable cosmetic sheet which is attached to a part to be stuck and is used in contact with water or hot water, The present invention relates to a cosmetic sheet having a foaming property superior to a hand-drinkability and a feeling of use, while allowing a facilitating action to be attached to a part to be adhered to the skin. More particularly, the present invention relates to a cosmetic sheet for use in a one-step carbonate sheet mask or the like which generates carbon dioxide gas by reacting with water in water or a serum / lotion.

BACKGROUND ART A technique of generating carbon dioxide gas by mixing an acidic component such as a carbonate and an acidic component such as an organic acid in the presence of water has been conventionally used in cosmetics conventionally in anticipation of a massage action and a blood circulation promoting action. For example, Patent Document 1 discloses a method in which a first carbon dioxide gas generating agent (first material) selected from sodium hydrogen carbonate and ammonium hydrogen carbonate (first material), which is expected to have a massage effect by a foaming action, and calcium carbonate, , 10 to 40 parts by weight of the first material, 65 to 20 parts by weight of the second material (second material), 100 parts by mass of the total amount of the carbonic acid gas generating agent (second material) obtained from the tartaric acid, Has been proposed. Then, water is added to the foamable cosmetic material, and the first material and the second material are kneaded and reacted with water to generate carbonic acid gas. By bringing the natural material into contact with the skin, Also disclosed is a method of using a foamable cosmetic material packed with a stimulus. However, since the foamable cosmetic material is intended to foam the powder by measuring the powder before the pack is packed, the handling is troublesome, the viscosity of the obtained resultant mixture is low, and the massage action and the blood circulation promoting action are sufficiently obtained It is difficult to catch. In addition, it is difficult to expect a satisfactory massaging effect after actually contacting the skin. When such a foamable cosmetic product is used as a pack material, it is troublesome to separately prepare a pack sheet, pack the cosmetic material on the sheet, and then pack it on the face.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a plan view of a face mask made from a cosmetic sheet of the present invention.

Inner layer

The foamable cosmetic sheet of the present invention is a sheet having a total weight of 40 to 300 g / m ² , containing 1 to 100% by weight of a cosmetic composition containing (a) a carbonate, an organic acid and a foam stabilizer.

The amount is preferably 5 to 60% by weight, more preferably 10 to 40% by weight. If the amount is less than 5% by weight, the effect of foaming the carbon dioxide gas is insufficient, and if the amount exceeds 60% by weight, the balance between the foaming effect and the exfoliation effect becomes poor, and sufficient effect can not be obtained.

Examples of the "organic acid" used as the cosmetic (a) cosmetic composition of the present invention include organic acids such as formic acid, acetic acid, propionic acid, butyric acid, valacic acid, oxalic acid, malonic acid, succinic acid, glutaric acid, adipic acid, pimelic acid, fumaric acid, Wherein the acid is selected from the group consisting of phthalic acid, isophthalic acid, terephthalic acid, glutamic acid, aspartic acid, glycolic acid, malic acid, tartaric acid, citric acid, lactic acid, hydroxyacrylic acid, Sodium pyrophosphate, sodium pyrophosphate, sodium pyrophosphate, sodium hexametaphosphate, potassium hexametaphosphate, sodium pyrophosphate, sodium pyrophosphate, sodium pyrophosphate, potassium pyrophosphate, potassium pyrophosphate, sodium pyrophosphate, , And sulfamic acid. The above components can be used alone or in combination of two or more, and the blending amount is 5 to 60% by weight, more preferably 10 to 40% by weight. When the amount is less than 5% by weight, the effect of foaming of carbon dioxide gas is insufficient, and when it exceeds 60% by weight, the balance between the foaming effect and the exothermic effect becomes poor, and sufficient effect can not be obtained.

Examples of the "foam stabilizer" used in the cosmetic of the present invention include powder obtained from various inorganic compounds or organic compounds, and water-soluble polymers. Among them, examples of powder components include talc, kaolin, mica, sericite, muscovite, gold mica, synthetic mica, purplish mica, biotite, rich aumo, palmycite, magnesium carbonate, calcium carbonate, aluminum silicate, Barium sulfate, barium sulfate, calcined diffusing calcium, calcium phosphate, fluorine apatite, hydroxyapatite, ceramic powder, metal soap (millie), calcium carbonate, calcium carbonate, calcium phosphate, barium calcium phosphate, magnesium silicate, strontium silicate, tungstic acid gold salt, magnesium, silica, (Nylon powder), polyethylene powder, poly (amyl alcohol), polyvinyl pyrrolidone, polyvinyl pyrrolidone, polyvinyl pyrrolidone, polyvinyl pyrrolidone, polyvinyl pyrrolidone, Methyl methacrylate powder, polystyrene powder, copolymer resin powder of styrene and acrylic acid, benzene aniline resin powder, poly 4 fluorinated ethylene powder, Organic powder such as chitan's dioxide powder, there may be mentioned inorganic white pigments such as zinc oxide. The above-mentioned one or two kinds may be used. In addition, these powders are sufficient as powders for general cosmetics, and are not limited to these components.

On the other hand, examples of the water-soluble polymer include natural polymers, semi-synthetic polymers, and synthetic polymers. Examples of natural polymers include natural gums such as gum arabic, carrageenan, galactan, agar, corn gum, guar gum, tragacanth gum, pectin, mannan, locust bean gum, wheat starch, rice starch, corn starch, At least one member selected from the group consisting of cardone, xanthan gum, succinoglucan, dextran, hyaluronic acid, pullulan, albumin, casein, collagen, gelatin and fibroin.

The blending ratio of the foam stabilizer powder and the water-soluble polymer is 0.1 to 50% by weight, preferably 1 to 30% by weight in view of usability. When the amount is less than 0. 0 wt%, the effect of foaming of carbon dioxide gas is insufficient. Therefore, when the amount exceeds 50 wt%, the balance between the foaming effect and the exothermic effect becomes poor, and sufficient effect can not be obtained.

In addition, the cosmetic (a) of the present invention may contain a heat-generating substance in order to further promote blood circulation.

Examples of the heat generating material, include inorganic anhydride, hydrate, etc., and the calcium chloride _{(CaCl 2, CaCl 2 · H} 2 O, CaCL 2, 2H 2 O), magnesium chloride _{(MgCl 2, MgCl 2 · 2H} 2 O, MgCl ₂ · 4H ₂ O), aluminum chloride _{(AlCl 2, AlCl 2 · 6H} 2 O), ferric chloride _{(FeCl 3, FeCl 3 · 2.5H} 2 O), zinc chloride (ZnCl _2), such as chloride; magnesium sulfate (MgSO ₄ , MgSO ₄ .H ₂ O, MgSO ₄ .4H ₂ O), zinc sulfate (ZnSO ₄ .H ₂ O), ferrous sulfate (FeSO ₄ , FeSO ₄ .H ₂ O) ₂ (SO _{4) 3),} calcium sulfate _{(CaSO 4, CaSO 4 · 1} / 2H 2 O, CaSO 4 · 2H 2 O) sulfate and the like; Other dry alum, calcium oxide (CaO), sodium metaphosphate, fatigue (Na ₂ HPO ₄ ), sodium hydrogen phosphate, trisodium hydrogen phosphate, and the like. In addition, the amount of heat generated by such a heating material is specific to the type thereof, and generally, the smaller the number of crystals in the same inorganic material, the larger the amount of heat generated. These can be used alone or in combination of two or more. They are prepared in accordance with the purpose for which the temperature is 10 to 80 ° C by reaction with water. When used as cosmetics, they are controlled at 20 to 50 ° C . The amount of the exothermic substance is 10 to 85% by weight, preferably 20 to 70% by weight. When the content is less than 10% by weight, the exothermic effect of carbon dioxide gas is insufficient. Therefore, when the content is less than 85% by weight, balance between the foaming effect and the exothermic effect becomes poor and a sufficient effect can not be obtained.

In the cosmetic sheet of the present invention, any sheet may be used as long as the inner layer portion contains the cosmetic material (a), but the inner layer may be composed of (a) 10 to 80 wt% of cosmetic material containing carbonate, organic acid and foam stabilizer (A) + (b) + (c), (b) 20 to 95% by weight of thermally adhesive fibers having a fineness of 1 to 4.4 dtex, or (c) = 100% by weight] as the main component and an inner layer portion by an airlaid method having a weight of 10 to 200 g / m ² .

It is needless to say that the layered portion in the cosmetic sheet of the present invention does not contain (b) thermally adhesive fibers or (c) cellulose-based pulp, and (a) In this case, when the cosmetic sheet of the present invention is prepared by the air-laid method laid down on the back side, it is only necessary to drop the cosmetic material on the basic woven fabric by the air laid method (a).

The inner layer portion is preferably formed by a method of forming a web layer (inner layer portion) including (a) a cosmetic powder in powder form, (b) thermoadhesive fiber in powder form, or (c) cellulosic pulp in air layer method. That is, the mixture containing the components (a) and (b) or (c) is discharged from a single pedestal placed on the porous net comb bear or a plurality of pedestals, The net conveyor image is formed into the web layer (inner layer portion). At this time, on the net conveyor, if the two layers that become the carrier sheet are placed first, a laminate of the web layer (inner layer portion) and the two-layer portion which becomes the carrier sheet is obtained at once. Thereafter, the laminate is laminated on the surface layer portion in an in-line or outline and subjected to hot air treatment to form interlaminar bond of the airlaid layer and thermal adhesion with the carrier sheet (inner surface layer) and the back surface layer.

At this time, the web layer is mixed with heat-adhesive fibers and mixed, and (a) the effect of preventing the fixing and dislodging of the powder constituting the cosmetic and the strength of the interlayer peeling strength can be expected.

Here, the cosmetic composition (a) used in the web layer constituting the inner layer portion is as described above. (a) the mixing ratio of the web layer of the cosmetic composition is 10 to 80% by weight, more preferably 20 to 80% by weight. If it is less than 10% by weight, the pack effect on the skin, the cleaning effect, and the cleansing effect deteriorate. On the other hand, even when the content exceeds 80% by weight, there is no great difference in the duration of foaming, and above all, it is difficult to preserve the strength of the web layer, and the dropout of powder during manufacturing, do.

In addition, in the inner layer portion, various kinds of soap spices, natural surfactants, deodorants, antibacterial agents, fragrances, moisturizers, various vitamins, fragrances (natural fragrance, synthetic fragrance, And the like.

As the thermally adhesive fiber (b) used in the web layer constituting the inner layer portion, the thermally adhesive composite fiber is favorable. For example, a core-sheath type having a low melting point component as a sheath component and a high melting point component as a core component, a side-by-side type having a low melting point on one side and a high melting point component on the other side. Examples of combinations of the two-side components of the composite fiber include PP (polypropylene) / PE (polyethylene), PET (polyethylene terephthalate) / PE, PP / low melting point copolymer PP, PET / low melting point copolymer polyester have.

Examples of the low-melting-point copolymer polyester include polyethylene terephthalate, polypropylene terephthalate, and polybutylene terephthalate as basic skeletons, aromatic dicarboxylic acids such as isophthalic acid and 5-metal sulfoisophthalic acid, , Aliphatic dicarboxylic acids of sebacic acid, and modified copolymers of aliphatic and alcohol such as diethylene glycol, propylene glycol and 1,4-butanediol.

The melting point of the thermal bonding component as the low melting point component is usually from 100 to 160 ° C, and the ideal temperature is from 110 to 155 ° C. If it is less than 100 ° C, the heat resistance is low as a nonwoven fabric, and when the sheet is wetted with hot water, the strength of the sheet may be weakened. On the other hand, if it exceeds 160 ° C, the heat treatment temperature must be increased in the nonwoven fabric manufacturing process, so that the productivity is lowered and impractical, and the adhesion effect by heating and integrating the web layer and the front and back layers can not be expected.

Here, the fiber length of the thermally adhesive fiber (b) is 3 to 10 mm, ideally 3 to 6 mm, because the production method of the web layer is also an airlaid method. When the fiber length is less than 3 mm, the effect is not sufficient for increasing the strength. On the other hand, when the fiber length exceeds 10 mm, the fibers tend to aggregate, and the quality and the quality of the substrate tends to deteriorate.

The fineness of the heat-adhesive fiber (b) is 1 to 4.4 dtex, and ideally 1.5 to 3.3 dtex. In the case of less than 1 dtex, in forming a wave by the eared method, since the thin fibers tend to be bundled together, mixing with other fibers becomes difficult, so that the risk of occurrence of unevenness in the base quality and aggregation And (a) the elution of the cosmetic powder in powder form from the web layer takes too much time, which is not suitable for practical use. On the other hand, in the case of a thick fiber exceeding 4.4 dtex, a hard texture is obtained, and a smooth texture is not felt when the skin is in contact with the skin. Further, The result of addition, dropout prevention, strength impartation, heat sealability and the like becomes weak.

(b) The thermally adhesive fiber may be crimped or not, or may be stretched. In the case of crimping, any of three-dimensional (three-dimensional) crimped fibers such as zigzag type two-dimensional crimped fiber and spiral type or omnid type can be used.

The proportion of the thermally adhesive fibers (b) in the web layer is 20 to 95 wt%, and ideally 20 to 80 wt% in the components (a) to (c). If the amount is less than 20% by weight, the effects of (a) supplementing, fixing and dropping prevention of the cosmetic powder in powder form can not be secured. On the other hand, if it exceeds 95% by weight, not only the sterility of the city after the heat treatment disappears, but also the state of covering the periphery of the powdery cosmetic material with the heat-adhesive fibers, The feeling of use due to foaming is remarkably deteriorated.

In addition, the cellulose (c) pulp used in the web layer has the function of holding the powder (a) cosmetics and also retaining moisture at the time of use of the pack, cleaning, cleansing, and the like.

(c) Examples of the cellulose-based pulp include those obtained by pulverizing non-wood pulp such as wood pulp, linter pulp, and burse gas.

(c) the mixing ratio in the cellulose based thermal web layer is 0 to 60% by weight, ideally 5 to 40% by weight. If it is more than 60% by weight, tensile strength as a web layer or strength between layers may be deteriorated, especially strength due to air during wetting is not preferable.

In the web layer of the present invention, the same polyolefin-based synthetic pulp as (d) cellulose pulp may be used as the pulp.

The polyolefin synthetic pulp (d) is, for example, a polyolefin in a high-temperature and high-pressure state, a dispersion liquid composed of a solvent for a polymer selected from aliphatic hydrocarbons and / or aromatic hydrocarbons having a boiling point lower than the boiling point of water, The dispersion liquid at a temperature at which substantially all of the solvent evaporates or does not cause substantial evaporation of water is released into the pressing region through the nozzle upon rapid release into the reduced pressure region and the polyolefin is recovered as a fibrous material dispersed in water , And a fibrous substance dispersed in water is mixed with a surfactant and then refined or refined. The method for producing the polyolefin-based synthetic pulp is described in, for example, Japanese Patent Laid-Open Publication No. 52-47049, column 1, and column 3, line 5 to column 19, , That is, a method for producing a polyolefin-based synthetic pulp composed of fibrin-like fibers which requires a supplementary action of the hygroscopic-component body, it is not always necessary to admit such a method.

The polyolefin synthetic pulp suitably has an average fiber length of 0.5 to 3 mm and an average fiber diameter of about 1 to 100 mu m.

As commercial products of polyolefin synthetic pulp, SWPE790, E400, EST-8, E620, UL410, NL490, AU690, Y600, ESS-5, ESS-2, E380, E780, E90, UL415 .

Such a polyolefin-based synthetic pulp (d) has a multi-branched fiber structure (fibrillated, multi-molecular weight, requiring a high proportion of surface area), and thus is required to have excellent characteristics in capturing the powdery (a) cosmetic. Further, when the sheet is sprayed onto the base sheet by the air-laid method, the web layer in which the polyolefin synthetic pulp (d) and the powdery (a) cosmetic material are integrated in the air stream is uniformly recorded on the sheet.

The mixing ratio (weight ratio) of the polyolefin-based synthetic pulp (a) and the cosmetic material (d) forming the web layer is 1 / 0.2-1 / 2, ideally 1 / 0.25-1 / 1.8. (d) If the amount of the polyolefin-based synthetic pulp is too small, the functional ability of the powdery (a) cosmetic material is deteriorated and the powder tends to fall off. On the other hand, if the amount of the powdery cosmetic composition is too small, the packing effect and the cleaning effect of the sheet produced are lowered, and this is not the intention of the present invention.

 In addition to these constituent components, the web layer for forming the inner layer portion may contain, for example, PP fiber, PET fiber, PBT fiber, nylon 6 fiber, nylon 6 or 6 fiber, aromatic polyamide fiber , Acrylic fiber, hemp, rayon, viscose fiber, cotton fiber and the like within a range not hindering the effect and effect of the present invention. In this case, the ratio with other fibers is preferably less than 30% by weight. If it is 30% by weight or more, the fibers that do not affect the strength of the nonwoven fabric and the heat sealability, but are not thermally adhesive, tend to fall off during use.

The weight of the web layer to be formed by the air-laid method is 20 to 250 g / m ² , and ideally 40 to 200 g / m ² . When it is less than 20 g / m ² , the packing effect, the cleaning effect, and the feeling of use due to foaming are lacking, and the nonwoven fabric strength and heat sealing strength are lowered. On the other hand, if it exceeds 250 g / m ² , it becomes too thick and is like a board, which is not preferable because it lacks flexibility.

The airlaid method for forming the web layer constituting the inner layer portion of the present invention is easily fibrillated into short fibers by the airflow as compared with the conventional dry nonwoven fabric manufacturing method such as the card method or the like, , A good nonwoven fabric can be obtained with good background texture, i.e., uniformity, and a web layer can be formed all at once while mixing powders, which is suitable for the present invention. The uniformity of the nonwoven fabric is an important requirement for a packed effect and a high cleanliness performance in applications such as pack materials, skin cleansing, and feeling of use due to foaming, , A spun bond nonwoven fabric, and a meltblown nonwoven fabric. Further, according to the present manufacturing method, there is also an advantage that the strength ratio of the length / width is close to 1/1.

The ideal state of the inner layer portion is as follows, and can be appropriately selected and used in the state of actual use.

(1) No pulp

(a) 10 to 80% by weight of cosmetic material

(b) 95 to 50% by weight of heat-

(c) Cellulosic pulp 0 wt%

[(A) + (b) + (c) = 100% by weight]

(1) The pulp-free state is characterized in that the mixing ratio of the thermally adhesive fibers is large, so that the resulting cosmetic sheet is strong in strength and has a large powder (cosmetic) dropout preventing action.

(2) pulp small amount mixing

(a) 10 to 80% by weight of cosmetic material

(b) 80 to 20% by weight of heat-

(c) Cellulose-based pulp     More than 0 wt% to less than 40 wt%

[(A) + (b) + (c) = 100% by weight]

The state of (2) pulp small amount mixing type has intermediate characteristics of (1) and (3) described above when it is obtained as a cosmetic sheet.

(3) pulp bulk mixing

(a) 10 to 80% by weight of cosmetic material

(b) 40 to 20% by weight of heat-

(c) 40 to 60% by weight of cellulose-

[(A) + (b) + (c) = 100% by weight]

In the case of (3) pulp mass mixing type, when it is obtained as a cosmetic sheet, it is easy to absorb and retain a large amount of water at the time of yarn use, so that the solubility of moisture in the powdery cosmetic material is smooth, Excellent.

The front and back layers (inner layer and The backside layer )

A make-up anpak sheet, wherein the inner layer portion of the present invention, ideally, of a weight of 10 ~ 50g / m ^2, spun-less nonwoven fabric, Thermal bond nonwoven fabric, a breath-base non-woven fabric, a spun bond nonwoven fabric, air-laid nonwoven fabric, At least one air-permeable sheet selected from the group of wet-laid nonwoven fabric, woven fabric, gauze, perforated sheet and cold-rolled sheet is laminated.

Particularly, since the spunless nonwoven fabric is in a sheet state by the cross-linking between fibers, the fibrous / resinous binder is reduced in number (even if it is zero) and is characterized by softness.

As the material of the breathable sheet, any of shredded fibers, regenerated fibers, and natural fibers may be used, or mixed fibers may be used. Of these, polyester fibers, polypropylene fibers, acrylic fibers and the like have good water resistance and are strong.

Further, regenerated fibers such as rayon and tencel are suitable for use in a wet state because of their water-retentive properties.

In addition, natural fibers such as cotton and pulp are water-retentive and soft to the skin.

When the heat-sealing method is used to integrate with the inner layer portion, the air-permeable sheet may be mixed with binder fibers in an amount of about 50% by weight or less for the fibers used in heat-bonding (b) used in the inner layer portion.

Among the breathable sheets, a spunless nonwoven fabric mainly made of rayon fibers and / or tencel fibers is preferable in terms of softness and water retention.

On the basis of making the decorative sheet of the present invention by the air laid method, first, the air permeable sheet serving as the back surface layer is placed on the net comb bear as the carrier sheet, and the web layer as the inner layer is deposited thereon, Can be made into a composite sheet.

For example, a breathable sheet (back layer) is placed on a net comb bear to form a web layer to be an inner layer, and a breathable sheet to be a surface layer is laminated in an inline or outline.

In addition, the breathable sheet used for the front and back layers is ideally a sheet made of a material having thermal adhesiveness and water resistance, and is excellent in air permeability. The air-laid method is a method of spraying a mixture of fibers and air from the top of the air-permeable material and drawing the air from the bottom by suction, thereby forming a fiber layer on the air-permeable material. The air permeability by JIS L1096 A method (Gareth method) is ideally 0.5 to 2 seconds / 300 cc.

The density of the breathable sheet as the front and back layers is usually 10 to 50 g / m ² , and ideally 12 to 40 g / m ² . When it is less than 10 g / m ² , it is difficult to form a web layer, and it is difficult to prevent falling off of cosmetic powder contained in the inner layer portion. On the other hand, if it exceeds 50 g / m ² , the penetration of water into the inner layer portion becomes insufficient, and the passage of liquid (cosmetic liquid dissolved in cosmetics or the like) through the inner layer portion is insufficient and too thick, There are drawbacks.

The fineness of the fibers constituting the breathable sheet is usually 0.1 to 6 dtex, and ideally 0.5 to 5 dtex. The cosmetic sheet of the present invention is not preferable because it is expected that the skin will be damaged if the thinner the skin is, the more smooth the skin and the thicker the skin.

By laminating the air-permeable sheet on both sides of the inner layer portion, the handling property is improved and the strength of the resulting cosmetic sheet can be reinforced.

In the case where air-laid nonwoven fabric is employed as the breathable sheet used for the front and back layers, (b) such as used in the inner layer portion in the spouting portion which is located on the porous net conveyor, A web layer to be the air permeable sheet is formed on the net conveyor while being sucked in the air suction portion arranged on the lower side of the net conveyor and the web layer to be the inner layer is formed thereon, (b) a web layer having a thermally adhesive fiber as a surface layer is formed.

The total weight of the inventive cosmetic sheet composed of the backside layer / inner layer portion / surface layer of the present invention is 40 to 300 g / m ² , and ideally 50 to 250 g / m ² . When it is less than 40 g / m ² , the effect as a pack material, the cleaning effect and the cleansing effect are lowered, and the strength is lowered, and practicality is lacking. On the other hand, in the case of a steel density exceeding 300 g / m ² , when the packing effect or the cleaning effect is proportionally increased, the cost is lowered, the production cost is increased, the merchantability is lowered, the flexibility is lowered, .

The thermally adhesive fibers (b) may be blended with various additives or subjected to surface treatment. For example, a perfume, a coloring agent, an antibacterial agent, a deodorant, an antiseptic agent, a neoprotective agent and the like can be mentioned.

Such additives and surface treatment agents may be treated including a back layer, an inner layer portion, and a surface layer web layer.

Surface layer / Inner layer , Inner layer / Inner layer  Integrated

The integration with each of these layers may be achieved by separately forming each layer and integrating them, or forming a multi-layer structure at once. In this case, the air-laid method is suitable.

Examples of the integration method include (1) thermal bonding, (2) binder treatment, and (3) entanglement.

(1) Thermal bonding: It is better to add binder fibers to each layer. Examples of the binder fiber include (b) thermally adhesive fibers used in the inner layer portion.

(2) Binder treatment: Spraying of a solvent of a hot-melt resin on a surface to be adhered, dispersion / heating of a hot-melt powdery resin, a liquid chemical binder cord or spraying, and heat treatment.

(3) Lack: Surface layer / inner layer part / inner layer are integrally laminated and knocked down with a needle punch or the like.

During the integration process, the inner layer is formed by the air-laid method. For example, the inner layer is formed by a carrier sheet, the inner layer is formed by airlaying and then the superficial layers are integrated to be integrated, This is the most desirable technique. Details of the (1) heat treatment are as follows.

Heat treatment:

In the cosmetic sheet of the present invention, it is preferable to heat treat the laminate composed of the surface layer / inner layer portion / inner layer obtained as described above. Examples of the heat treatment include a hot air treatment and a low-pressure heat treatment after hot air treatment.

Among them, in the case of using heat-bondable conjugate fibers as heat-bondable fibers, the hot-air treatment for forming bonds between the fibers requires a temperature not lower than the melting point of the low-melting-point component of the conjugate fibers. However, when the melting point of the component is higher than the melting point by 30 占 폚 or higher or higher than the boiling point of the high melting point component (the core component of the core-sheath type conjugated fiber or the high melting point component of the side-by-side type conjugated fiber) It is easy to grow and deteriorate the background texture and deteriorate in severe cases.

The hot air treatment temperature is usually 110 to 190 占 폚, but the ideal temperature is 120 to 175 占 폚.

After hot air treatment, hot pressure treatment under low pressure, specifically, pressure calender treatment may be applied. It is preferable to use a metal roller of a smooth surface or a combination of a metal roller and an elastic roller because a uniform pressure is applied to the roller used in the calendering process, but a multi-stage roller may be used. In addition, if the effect of the present invention is not impaired, an emboss roller on the uneven surface may be used.

In the case of the calendering process, it is preferable to pressurize at an arbitrary temperature of room temperature (non-heating) to high temperature so as to simply control the thickness. The pressure can be appropriately selected to be the desired thickness. The temperature of the surface of the roller is required to be not lower than the melting point of the low melting point component of the thermosetting conjugated fiber as long as it improves the strength, surface abrasion resistance, . However, when the melting point of the fiber is higher than the melting point of the low melting point component by 30 占 폚 or higher, or when the melting point of the high melting point component (the core component of the core-sheath type conjugated fiber or the high melting point component of the sidebishide type conjugated fiber) Not only is the shrinkage increased, but also adheres to the surface of the rollers, which results in lack of fairness. In the case of less than the boiling point, the bonding reinforcement between the natural fibers becomes insufficient.

The heat treatment temperature in the case of reinforcing the bonding between the fibers is usually 110 to 190 占 폚, ideally 120 to 175 占 폚.

Further, the line pressure of the calendering process can be arbitrarily selected by causing the pressure to be uniformly applied in the width direction. In the case of high pressure, density, nonwoven fabric strength, interlaminar strength are increased and the thickness is reduced. In the case of low pressure, of course, there is an opposite effect. If the nonwoven fabric strength is emphasized, it is preferable that the pressure is as high as possible. If flexibility is important, it is desirable to have a low pressure. The linear pressure of the calendering process can be arbitrarily selected in the range of usually 5 to 50 kgf / cm. Further, the interval may be arbitrarily set between one roller. When the temperature of the roller in contact with the surface layer is high or when the pressure is high between the rollers, the surface state is smoothed, so that the action of the pack, clean, smudge, not.

The thickness of the decorative sheet of the present invention to be obtained is usually 0.4 to 2.5 mm and ideally 0.6 to 2 mm. The weight of the web layer (inner layer portion) (40 to 300 g / m ² ) It can be set according to the purpose.

The total weight of the cosmetic sheet of the present invention is 40 to 300 g / m ² , and ideally 60 to 250 g / m ^{2 as described above} . When the total weight is less than 40 g / m ² , the pack effect, the cleaning effect, the cleansing effect, and the like are deteriorated and the strength is low, which is not practical. On the other hand, in the case of a high density exceeding 300 g / m ² , the proportion of the increase in the cleaning effect and the pack effect is reduced, resulting in an increase in the production cost, lack of merchandise property, loss of flexibility, The handling becomes worse.

When the cosmetic sheet of the present invention is used as a face mask for a pack, a plurality of cosmetic sheets may be laminated and one mask face mask may be used one by one as shown in Fig. The face mask 10 is formed of the cosmetic sheet of the present invention, and is entirely cut into an elliptic shape having a size that covers the entire face. When the face mask 10 is put on the face, the face 11 is formed in a portion that is easily fritted to the face and abuts on both eyes, and the face mask 10 is cut into a long oval shape laterally so as not to cover the eyes. In addition, the portion that touches the mouth is formed with a bent portion 12 that is cut in a long oval shape laterally so as not to cover the mouth. In addition, a U-shaped incision 13 is formed so that the portion contacting the nose can be tilted upwards in conformity with the shape of the nose. Further, in the outer circumference 14 of the face mask 10, the incision 15 is designed in four parts.

When using the face mask 10, lightly dampen the entire face mask 10 with water and gently adhere to the face. By doing so, carbon dioxide gas is generated from the cosmetic (a) loaded in the inner layer of the face mask, and the carbon dioxide gas generated by the action of the foam stabilizer is retained and the carbon dioxide gas effect is maintained. At this time, if the above-mentioned exothermic substance is contained, blood circulation on the face is promoted.
