Description

  The present invention is an effervescent material that can be used for packs and the like, and is impregnated with a non-aqueous medium such as massage oil, and can improve cosmetic parts and keratinous parts where moisture is desired for the skin. Can be easily attached to the desired part of the skin, foamed by contact with water or hot water, and can provide sufficient massage action and blood circulation promoting action according to the desired part of the skin. The present invention relates to a skin modified sheet that is excellent in feeling of use, has a long foaming duration, and has excellent moisture retention and moisturizing effects after use.

Technology that mixes basic compounds such as carbonates and acidic components such as organic acids in the presence of water to generate carbon dioxide is a traditional cosmetic and health promotion product that expects massage and blood circulation promotion. It is used in various ways.
For example, Patent Document 1 discloses a first carbon dioxide gas generator (first agent) selected from sodium hydrogen carbonate and ammonium hydrogen carbonate, and calcium sulfate, citric acid, ascorbic acid. A second carbon dioxide generator (second agent) selected from tartaric acid, and an additive selected from skim milk powder and starch, and 10 to 40 parts by weight of the first agent in a total amount of 100 parts by weight, A foamable cosmetic material containing 65 to 20 parts by weight of the second agent has been proposed. Then, water is added to the foamable cosmetic to form a kneaded mixture, and the first agent and the second agent are reacted under water to generate carbon dioxide, thereby bringing the kneaded product into contact with the skin. Thus, a method of using an effervescent cosmetic material that packs with stimulation by bursting of carbon dioxide gas bubbles is also disclosed. However, since this foamable cosmetic is intended to take out the powder before packing and contact with water for foaming, it lacks handling properties, and the resulting kneaded product has a low viscosity, It is difficult to sufficiently obtain a massage action and a blood circulation promoting action at a desired portion of the skin. In addition, it is difficult to expect the persistence of the massage effect after actually contacting the skin.
Moreover, when using such foamable cosmetics as a pack agent, a sheet for packing must be prepared separately, and the cosmetic must be applied to the sheet and then packed on the face. There are aspects that lack.
In addition, such foamable cosmetics also have a problem that the foamed foam has a short duration.

In addition, the skin-modifying sheet provided with a non-aqueous medium such as the massage oil of the present invention not only obtains a blood circulation promoting effect for a short time, but also moisturizes the skin after use for a long time and prevents moisture from drying. As a preferred application, it can be used for skin care sheets, face masks, or packs for parts that require modification of the skin condition that can be used on various parts of the face such as elbows, knees, and fingertips. Sheet.

The foamable skin-modifying sheet of the present invention contains at least a carbonate, an organic acid, and a foam stabilizer in the inner layer portion thereof, and foaming occurs by adding moisture after adhering to the skin at a desired use site. Therefore, by utilizing the effect of the oil component, it is possible to suppress the foaming of carbon dioxide gas due to a rapid neutralization reaction, and an excellent blood circulation promoting action and massage action can be sufficiently obtained at a desired portion of the skin, and the foaming time can be reduced. Excellent sustainability. In addition, the skin modifying sheet of the present invention contains an foaming foam stabilizer in the inner layer portion of the fabric, so that it has an effect of exhibiting a gel shape with the foam stabilizer during use, and the effect of the oil component Together, the skin adhesion at the site of use is stable and the feeling of use is excellent. Furthermore, since the skin modifying sheet of the present invention is substantially non-aqueous during storage, carbonates and organic acids are mixed, but the influence of moisture contained in the air is also inhibited by oil components. Thus, the part to be stuck to the skin without foaming can be set to a desired position. Furthermore, the skin-modifying sheet of the present invention is also easy to use because the oil component improves the flexibility of the sheet due to the rigidity that becomes a disadvantage of the sheet only containing a powder such as a foaming agent. Because of the significant improvement, the desired skin position to be used can be determined and then brought into contact with water or hot water for foaming. When the oil component is not included, it is difficult to accurately stick the sheet to a desired position. In addition, by using the oil component, the packaging material can be simplified in order to prevent the foaming component from reacting with moisture in the air, and after taking out the sheet from the packaging material, a hot and humid atmosphere such as a bathroom. Even underneath, it is difficult for the foaming reaction due to surrounding moisture to be accelerated, and the product is excellent in stability before storage and use.
In addition, since the base sheet is impregnated with a non-aqueous medium such as massage oil, the skin modifying sheet of the present invention does not drop off the powder sheet located in the inner layer portion of the fabric sheet, and the massage oil So that there is no generation and growth of inhibitory bacteria, and when the sheet is attached to a desired position and then foamed by applying water, the foaming duration will be prolonged due to the effect of the oil, and foaming will occur. There is a merit that the effect lasts long.
In addition, since the skin modifying sheet of the present invention contains massage oil and the like, and has good adhesion to the skin, it can be easily adhered to the skin, for example, on the elbow or knee. And after pasting at a desired position, it is possible to foam by attaching moisture.
In addition, the effect of massage oil or the like can maintain moisture for a long time even if face washing or wiping is performed after use.
Therefore, the skin modifying sheet of the present invention is particularly useful for packs and the like, but if added, it is effective for improving keratinous sites where moisture is desired for the skin.

The blending amount of the foam stabilizer powder and the water-soluble polymer is 0.1 to 50% by weight, preferably 1 to 30% by weight based on usability. If it is less than 0.1% by weight, the foaming effect of carbon dioxide gas is insufficient. On the other hand, if it exceeds 50% by weight, the balance between the foaming effect and the heat generation effect is deteriorated and a sufficient effect cannot be obtained.

In addition, the (a) cosmetic of the present invention can contain a pyrogen in order to further improve blood circulation promotion.
Such pyrogens, anhydrides inorganic, hydrate and the like, 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 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), sulfates such as aluminum sulfate (Al ₂ (SO ₄ ) ₃ ), calcium sulfate (CaSO ₄ , CaSO ₄ · 1 / 2H ₂ O, CaSO ₄ · 2H ₂ O); other dry alum, calcium oxide (CaO ), Sodium metaphosphate, sodium pyrophosphate, monosodium hydrogen phosphate (Na ₂ HPO ₄ ), disodium hydrogen phosphate, trisodium hydrogen phosphate, and the like. In addition, the amount of heat generated by these exothermic substances is unique depending on the type, and generally the amount of heat generated from the same inorganic material increases as the amount of crystal water decreases. These can be used alone or in combination of two or more thereof, prepared according to the purpose so that the temperature becomes 10 to 80 ° C. by reaction with water, and on the skin when used as a cosmetic. It is preferable to control so that it may become 20-50 degreeC. The amount of these exothermic substances is 10 to 85% by weight, preferably 20 to 70% by weight. If it is less than 10% by weight, the foaming effect of carbon dioxide gas is insufficient, and if it exceeds 85% by weight, the balance between the foaming effect and the heat generation effect is deteriorated, and a sufficient effect cannot be obtained.

The base sheet used in the present invention may be any sheet as long as the inner layer portion contains the above-mentioned (a) cosmetic material. The inner layer portion includes (a) carbonate, organic acid, and foam stability. 10 to 80% by weight of a cosmetic containing an agent, (b) 20 to 95% by weight of heat-adhesive fiber having a fineness of 1 to 4.4 dtex, and (c) 0 to 60% by weight of cellulosic pulp [where ( a) + (b) + (c) = 100% by weight] and having an inner layer portion by an airlaid method having a basis weight of 10 to 200 g / m ² is preferable.

The inner layer portion is formed by airlaid method to form a web layer (inner layer portion) containing powdery (a) cosmetic material, (b) heat-adhesive fiber, and (c) cellulosic pulp as necessary. Is preferred. That is, the mixture containing the above components (a) and (b) and, if necessary, the component (c) is jetted from the single or multiple jetting parts located on the porous net conveyor, A web layer (inner layer portion) is formed on the net conveyor while suctioning with the arranged air suction portion. At this time, if a later-described back layer serving as a carrier sheet is placed on the net conveyor in advance, a laminate of the web layer (inner layer portion) and the back layer serving as the carrier sheet can be obtained at once. Then, the surface layer is laminated inline or outline, and hot air treatment is applied to form an interlaid fiber-to-fiber bond and thermal adhesion to the carrier sheet (back surface layer) and the surface layer to be integrated as a nonwoven sheet. .
At this time, since the heat-adhesive fibers are mixed in the web layer, effects such as (a) prevention of fixing / falling off of the powder constituting the cosmetic and improvement of delamination strength can be expected.

  Here, (a) cosmetic used for the web layer constituting the inner layer portion is as described above. (A) The mixing rate of the cosmetic in the web layer is 10 to 80% by weight, preferably 20 to 80% by weight. If it is less than 10% by weight, the packing effect on the skin, the cleaning effect, and the feeling of use due to foaming are poor. On the other hand, even if it exceeds 80% by weight, there is no significant difference in the foaming duration, and it is difficult to ensure the strength as a web layer, and the amount of powder falling off during production, storage and transportation increases. And lacks practicality.

  The inner layer part can be used in combination with powdery (a) cosmetics and various soaps, natural surfactants, deodorants, antibacterial agents, fragrances and the like. .

  In addition, as the (b) heat-adhesive fiber used in the web layer constituting the inner layer portion, a heat-adhesive conjugate fiber is suitable. For example, a core-sheath type in which a low melting point component is a sheath component and a high melting point component is a core component, a side-by-side type in which one is a low melting point and the other is a high melting point component. Examples of combinations of both components of these composite fibers include PP (polypropylene) / PE (polyethylene), PET (polyethylene terephthalate) / PE, PP / low-melting copolymer PP, PET / low-melting copolymer polyester, and the like. . Here, examples of the low-melting point copolyester include polyethylene terephthalate, polypropylene terephthalate, polybutylene terephthalate, etc. as a basic skeleton, aromatic dicarboxylic acids such as isophthalic acid and 5-metal sulfoisophthalic acid, adipic acid, and sebacic acid. And a modified copolymer with an aliphatic polycarboxylic acid such as diethylene glycol, diethylene glycol, propylene glycol, 1,4-butanediol and the like.

  The melting point of the thermal adhesive component, which is a low melting point component, is usually 100 to 160 ° C., preferably 110 to 155 ° C. When the temperature is lower than 100 ° C., the heat resistance of the nonwoven fabric is low, and thus the strength of the sheet may be weakened when it is used wet with warm water. On the other hand, when the temperature exceeds 160 ° C., it is necessary to increase the heat treatment temperature in the nonwoven fabric production process, the productivity is lowered, and it is not practical, and the adhesive effect in the heat integration between the web layer and the front and back layers cannot be expected.

Here, (b) The fiber length of the heat-adhesive fiber is 3 to 10 mm, preferably 3 to 6 mm, because the web layer manufacturing method is the airlaid method. When the fiber length is less than 3 mm, the effect of increasing the strength is not sufficient. On the other hand, when the fiber length is more than 10 mm, the fibers tend to be entangled with each other, leading to deterioration of processability and texture.
The fineness of the (b) heat-adhesive fiber is 1 to 4.4 dtex, preferably 1.5 to 3.3 dtex. When it is less than 1 dtex, when forming a web by the airlaid method, thin fibers are easily entangled with each other, and mixing with other fibers becomes difficult, and the risk of uneven formation of the texture and occurrence of massive defects is increased. Or, it takes too much time to dissolve the powdery (a) cosmetic material from the web layer, which is not practical. On the other hand, in the case of a thick fiber exceeding 4.4 dtex, it becomes a hard texture, so it is applied to the gentleness to humans when affixed to the skin, and the number of fibers is reduced even at the same mixing ratio, so that it is powdery. (A) Effects such as capture of cosmetics, prevention of falling off, imparting strength, imparting heat sealability, and the like are diminished.

  (B) The heat-adhesive fiber may be crimped or not, and may be a strand chop. When crimped, both zigzag-type two-dimensional crimped fibers and spiral-type and ohmic-type three-dimensional (three-dimensional) crimped fibers can be used.

  The ratio of the (b) heat-bondable fiber in the web layer is 20 to 95% by weight, preferably 20 to 80% by weight in the components (a) to (c). If it is less than 20% by weight, the effect of capturing, fixing, and preventing the powdery (a) cosmetic material from being secured cannot be secured. On the other hand, if it exceeds 95% by weight, not only the flexibility of the sheet after heat treatment is lost, but also the powdery (a) cosmetic material is covered with many heat-adhesive fibers, and the pack effect, cleanness It has an adverse effect on the effect and the feeling of use due to foaming.

In addition, (c) cellulosic pulp that may be used for the web layer holds the powdery (a) cosmetic material and holds moisture during packing, at the time of cleaning, and during use.
(C) Cellulose pulp includes pulverized non-wood pulp such as linter pulp and bagasse in addition to wood pulp.
(C) The mixing rate of the cellulosic pulp in the web layer is 0 to 60% by weight, preferably 5 to 40% by weight. If it exceeds 60% by weight, the tensile strength and delamination strength as a web layer, particularly these strengths when wet, decrease, which is not preferable.

In addition, in the web layer of this invention, you may use together (d) polyolefin synthetic | combination pulp with said (c) cellulose pulp as a pulp.
Here, (d) the polyolefin synthetic pulp is, for example, a polyolefin solvent in a high temperature, high pressure state, a polymer solvent selected from aliphatic hydrocarbons and / or aromatic hydrocarbons having a boiling point lower than that of water, and A dispersion consisting of water, when rapidly released into the vacuum zone, removes the dispersion at a temperature at which substantially all of the solvent evaporates and does not cause substantial evaporation of water through the nozzle. It is obtained by releasing into the fiber, collecting the polyolefin as a fibrous material dispersed in water, and refining or refining the fibrous material dispersed in water with a surfactant mixed. The method for producing the polyolefin-based synthetic pulp is described in detail in, for example, the claims in the first column of JP-B-52-47049, column 3, line 5 to column 19, line 25. The gist of the present invention, that is, a method for producing a polyolefin-based synthetic pulp composed of fibrillar fibers having a trapping action for hygroscopic powder, is not necessarily limited to these.
As the polyolefin synthetic pulp, those having an average fiber length of 0.5 to 3 mm and an average fiber diameter of 1 to 100 μm can be suitably used.
Moreover, as a commercial item of this polyolefin synthetic pulp, SWP E790, E400, EST-8, E620, UL410, NL490, AU690, Y600, ESS-5, ESS-2, E380, E780 manufactured by Mitsui Chemicals, Inc. , E90, UL415, and the like.

  Since these (d) polyolefin-based synthetic pulps have a multi-branched fiber structure (fibrillated, multi-branched and have a high specific surface area), they have a characteristic of being excellent in powdery (a) cosmetic capturing properties. Further, when the carrier sheet is sprayed by the airlaid method, a web layer in which (d) the polyolefin synthetic pulp and the powdery (a) cosmetic material are integrated in the airflow is uniformly placed on the sheet. Will be.

  The mixing ratio (weight ratio) of the (d) polyolefin-based synthetic pulp and the (a) cosmetic material forming the web layer is 1 / 0.2 to 1/2, preferably 1 / 0.25 to 1/1. 8. (D) When there are too few polyolefin synthetic pulps, the capture | acquisition function of powdery (a) cosmetics will become inadequate, and powder will fall out easily. On the other hand, when there are too few powdery cosmetics, the pack effect of the sheet obtained and the cleaning effect are scarce, which is not intended by the present invention.

  In addition to these components, the web layer forming the inner layer portion includes, for example, PP fibers, PET fibers, PBT fibers, nylon 6 fibers, nylon 6,6 fibers, aromatics as fibers other than the heat-adhesive fibers. Polyamide fiber, acrylic fiber, hemp, rayon, viscose fiber, cotton fiber and the like may be mixed within a range not impairing the gist and effect of the present invention. In this case, the proportion of other fibers is preferably kept below 30% by weight. If it is 30% by weight or more, not only the strength of the nonwoven fabric and heat sealability will be affected, but fibers without thermal adhesiveness will easily fall off during actual use.

The web layer which is an inner layer formed by the airlaid method has a basis weight of 20 to 250 g / m ² , preferably 40 to 200 g / m ² . When it is less than 20 g / m ² , the pack effect, the cleaning effect, and the feeling of use due to foaming are poor, and the nonwoven fabric strength and heat seal strength are low, which is not suitable for practical use. On the other hand, if it exceeds 250 g / m ² , it is too thick and plate-like, and lacks flexibility, which is not preferable.

  The airlaid method for producing the web layer constituting the inner layer portion of the present invention is shorter in length than the existing dry nonwoven fabric manufacturing method such as the card method, and is easily defibrated to a single fiber by an air flow. Since fibers can be used, it has a feature that a non-woven fabric with extremely good texture, that is, good uniformity can be obtained, and it is possible to form a web all at once while mixing powders. Is preferred. Uniformity in the nonwoven fabric is an important requirement for the performance of the sheet material such as pack material, skin cleansing, and feeling of use by foaming, with less powder leakage, and large pack effect and cleansing effect. It is difficult to obtain with a card method nonwoven fabric, a spunbond nonwoven fabric, or a melt blown nonwoven fabric. Moreover, according to this manufacturing method, there is also a merit that the vertical / horizontal strength ratio is close to 1/1.

The preferable aspect of the above inner layer part is as follows, and can be suitably selected according to the state of actual use.
(1) No pulp (a) Cosmetics 10-80% by weight
(B) Thermal adhesive fiber 95-50% by weight
(C) Cellulose pulp 0% by weight
[However, (a) + (b) + (c) = 100 wt%]
This (1) pulp-free aspect is characterized in that the mixing ratio of heat-adhesive fibers is large, so that the resulting skin-modifying sheet is strong and has a great effect of preventing powder (cosmetics) from falling off. .

(2) Small amount of pulp mixed (a) Cosmetics 10-80% by weight
(B) Thermal adhesive fiber 80 to 20% by weight
(C) Cellulose-based pulp Over 0% by weight to less than 40% by weight [however, (a) + (b) + (c) = 100% by weight]
The aspect of this (2) pulp small amount mixing type has the intermediate characteristic of said (1) and following (3) as an obtained skin modification sheet.

(3) Mass mixing of pulp (a) Cosmetics 10-80% by weight
(B) Thermal adhesive fiber 40 to 20% by weight
(C) Cellulose pulp 40-60% by weight
[However, (a) + (b) + (c) = 100 wt%]
This (3) pulp mass mixing type mode makes it easy to absorb and retain a large amount of moisture during actual use as the resulting sheet, so that the powdery cosmetics dissolve smoothly in the moisture, and the pack effect Excellent cleaning effect.

The base material sheet of the present invention is preferably a spunlace nonwoven fabric, a thermal bond nonwoven fabric, an air-through nonwoven fabric, a spunbond nonwoven fabric, an airlaid nonwoven fabric, a wet nonwoven fabric having a basis weight of 10 to 50 g / m ^{2 on} the front and back of the inner layer portion. At least one breathable sheet selected from the group consisting of woven and knitted fabric, gauze, cotton sheet, perforated sheet and cold chill is laminated.
In particular, since the spunlace nonwoven fabric is formed into a sheet shape by interlaced fibers, it has a feature that it is soft because less fiber / resin binder is required (or zero).
The material of the breathable sheet may be any of synthetic fiber, regenerated fiber, natural fiber, or a mixed fiber thereof. Among these, synthetic fibers such as polyester fiber, polypropylene fiber, and acrylic fiber have good water resistance and are strong.
In addition, recycled fibers such as rayon and tencel are suitable for use by being wet because they have water retention.
Furthermore, natural fibers such as cotton and pulp have water retention and are gentle to the skin.
When the heat-adhesive method is used for integration with the inner layer portion, the air-permeable sheet is used as a binder fiber in the inner layer portion, and (b) about 50% by weight or less of the heat-adhesive fiber is mixed and used. Also good.
Of the breathable sheet, a spunlace nonwoven fabric mainly composed of rayon fibers and / or tencel fibers is preferred from the viewpoint of softness and water retention.

In making the substrate sheet of the present invention by the airlaid method, first, a breathable sheet as a back layer is placed on a net conveyor as a carrier sheet, and a web layer as the inner layer portion is deposited thereon. Thus, a composite sheet can be easily formed.
For example, a breathable sheet (back surface layer) is placed on a net conveyor to form a web layer serving as an inner layer portion, and a breathable sheet serving as a surface layer is laminated inline or outline.
The breathable sheet used for the front and back layers is preferably a sheet made of a material having heat adhesion and water resistance, and preferably has a larger breathability. The airlaid method is a method in which a fiber layer is formed on a breathable material by ejecting a mixture of fibers and air from the top of the breathable material and drawing air from the bottom by suction. Air permeability is an important requirement. The air permeability according to JIS L1096 · A method (Gurley method) is preferably 0.5 to 2 seconds / 300 cc.

The basis weight of the breathable sheet to be the front and back layers is usually 10 to 50 g / m ² , preferably 12 to 40 g / m ² . If it is less than 10 g / m ^2, it is difficult to form the web layer, and it is difficult to prevent the cosmetic powder contained in the inner layer part from falling off. On the other hand, when it exceeds 50 g / m ² , the penetration of water into the inner layer portion becomes insufficient, and the liquid (cosmetic liquid in which cosmetics and the like are dissolved) from the inner layer portion to the surface also becomes insufficient, resulting in a further increase in thickness. If it is too much, the texture will be damaged, and it will become hard.
In addition, the fineness of the fiber which comprises a breathable sheet is 0.1-6 dtex normally, Preferably it is 0.5-5 dtex. In the base sheet of the present invention, the finer fineness is gentle to the skin, and if it is too thick, the adhesion to the skin is inhibited and the skin is damaged, which is not preferable.
By laminating the air-permeable sheet on both surfaces of the inner layer portion, the handleability is improved and the strength of the obtained base sheet can be reinforced.

  In addition, when airlaid nonwoven fabric is adopted as a breathable sheet used for the front and back layers, it is the same as that used for the inner layer portion from a single unit or a large number of jetted portions located on the porous net conveyor (b ) A web layer serving as a breathable sheet is formed on the net conveyor while ejecting heat-adhesive fibers and sucked by an air suction section arranged on the lower surface of the net conveyor, and a web layer serving as the inner layer section is further formed thereon. Then, a web layer serving as a surface layer may be formed using (b) a heat-bondable fiber.

The total basis weight of the base material sheet of the present invention comprising the back layer / inner layer part / surface layer of the present invention is 40 to 300 g / m ² , preferably 50 to 250 g / m ² . If it is less than 40 g / m ² , the effect as a pack material, the cleaning effect, and the feeling of use due to foaming are poor, and the strength is low, making it difficult to withstand practical use. On the other hand, in the case of a high basis weight exceeding 300 g / m ² , the packing effect and the cleaning effect are less likely to increase proportionally, and the production cost is increased, resulting in lack of merchantability and loss of flexibility. , Handling for people deteriorates.

In addition, (a) cosmetics, (b) heat-adhesive fiber, (c) cellulosic pulp may contain various additives or may be surface-treated. For example, a fragrance | flavor, a coloring agent, an antibacterial agent, a deodorizing agent, an antifungal agent, a hydrophilizing agent etc. are mentioned.
These additives and surface treatment agents may be contained or treated in the web layers of the surface layer, the inner layer portion, and the back surface layer.

Integration of surface layer / inner layer part, back layer / inner layer part:
Integration with each of these layers may be performed after each layer is separately manufactured, or a multilayer structure may be formed all at once. In this case, the airlaid method is suitable.
Examples of the means for integration include (1) thermal bonding, (2) binder treatment, and (3) entanglement.
(1) Thermal bonding: Binder fibers are preferably included in each layer. Examples of the binder fiber include (b) a heat-bonding fiber used for the inner layer portion.
(2) Binder treatment: Examples include hot melt resin melt spraying on the adherend surface, hot melt powder resin spraying / heat melting, liquid chemical binder coating or spraying, and heat treatment.
(3) Entangling: Surface layer / inner layer portion / back surface layer are integrally laminated and entangled by needle punching.
Among these integration processes, the inner layer part is produced by the airlaid method. For example, the back layer is used as a carrier sheet, the inner layer part is formed by the airlaid method, the surface layer is overlapped and integrated, and heat bonding, etc. It is the most preferable means to integrate them. The details of this (1) heat treatment are as follows.

Heat treatment:
In the base material sheet of the present invention, it is preferable to heat-treat the sheet laminate comprising the surface layer / inner layer part / back surface layer obtained as described above. Examples of the heat treatment include hot air treatment and hot pressure treatment with low pressure after the hot air treatment.
Among these, as hot-air treatment for forming an interfiber bond, when a heat-adhesive conjugate fiber is used as the heat-adhesive fiber, a temperature equal to or higher than the melting point of the low-melting-point component of the conjugate fiber is required. However, if the melting point is 30 ° C. or higher than the melting point of the low melting point component, or the melting point of the high melting point component (the core component of the core-sheath type composite fiber or the high melting point component of the side-by-side type composite fiber), the heat shrinkage of the fiber. Is liable to be large, which leads to deterioration of the texture, and in extreme cases, it causes deterioration of the fibers, which is not preferable.
The hot air treatment temperature is usually 110 to 190 ° C, preferably 120 to 175 ° C.

  Further, after the hot air treatment, a hot pressure treatment under a low pressure, specifically, a low pressure hot pressure calendar treatment may be added. As a roller used for the calendering treatment, it is preferable to use a pair of metal rollers having a smooth surface or a combination of a metal roller and an elastic roller in order to apply a uniform heat pressure to the whole, but a multi-stage roller may also be used. In addition, an embossing roller with an uneven surface may be used as long as the gist of the present invention is not impaired.

In the case of calendering, the pressure may be applied at any temperature from room temperature (non-heated) to high temperature if it is simply for thickness adjustment. The pressure can be appropriately selected to achieve a desired thickness. The temperature of the roller surface is higher than the melting point of the low-melting component of the heat-adhesive conjugate fiber so as to reinforce the thermal bond between the fibers with a hot-pressure calender and improve strength, surface abrasion resistance, delamination prevention, etc. Temperature is required. However, if the melting point is 30 ° C. or higher than the melting point of the low melting point component, or the melting point of the high melting point component (the core component of the core-sheath type composite fiber or the high melting point component of the side-by-side type composite fiber), the heat shrinkage of the fiber. Not only tends to be large, but also sticks to the roller surface and lacks processability. When the temperature is lower than the melting point, it is a matter of course that the reinforcement between the fibers is not sufficient.
The heat treatment temperature for reinforcing the fiber-to-fiber bond is usually 110 to 190 ° C, preferably 120 to 175 ° C.

  Moreover, if the linear pressure of the calendar process is set so as to be a uniform contact pressure in the width direction, an arbitrary pressure can be selected. In the case of high pressure, the density, non-woven fabric strength and interlayer strength increase, and the thickness decreases. In the case of low pressure, of course, an adverse effect occurs. If importance is attached to the strength of the nonwoven fabric, a high pressure is preferred as much as possible. If flexibility is important, low pressure is preferable. The linear pressure of the calendar process can usually be arbitrarily selected in the range of 5 to 50 kgf / cm. Moreover, you may provide arbitrary clearance gaps between a pair of rollers. When the temperature of the roller in contact with the surface layer is high, or when the pressure between the rollers is high, the surface condition is smoothed, so the pack, cleaning, wiping, and scraping functions targeted by the present invention are deteriorated. However, it is not preferable.

In addition, although the thickness of the base material sheet of this invention obtained is 0.4-2.5 mm normally, Preferably it is 0.6-2 mm, but the fabric weight (40-300 g / m) of a web layer (inner layer part). ² ) and can be set according to the application.
The total basis weight of the base sheet of the present invention, as described above, 40~300g / ^{m 2,} preferably 60~250g / ^{m 2.} If the total basis weight is less than 40 g / m ² , foaming with a sufficient foaming feeling is poor, while if it exceeds 300 g / m ² , adhesion to the skin becomes difficult to obtain and the continuity of foaming time increases. In addition, the production cost is increased, so the merchantability is lacking.

<Skin modification sheet>
The skin modifying sheet of the present invention is such that a non-aqueous medium such as massage oil is further applied to the above base sheet.
A feature of the skin modified sheet of the present invention is that the above-mentioned base material sheet with cosmetics incorporated in the inner layer portion is impregnated with a non-aqueous medium such as massage oil, so that the powdery cosmetics can be removed or inhibited bacteria can be prevented. In addition to preventing the occurrence, the foaming duration is increased.
Moreover, since the skin modification sheet | seat of this invention contains nonaqueous media, such as massage oil, powdery (a) cosmetics do not fall out. In addition, the skin modified sheet of the present invention is remarkably easy to use because the flexibility of the sheet is improved by the oil component due to the rigidity that becomes a defect of the sheet containing only the powder such as a foaming agent, and the oil component improves the flexibility of the sheet. Since it improves, the adhesiveness to the skin used as the desired position to use increases, and after making it contact | adhere to skin, it can make it adhere and make a foam.
Furthermore, the skin modifying sheet of the present invention has an effect of promoting blood circulation by carbon dioxide gas foaming. In addition, the effect of massage oil or the like can maintain moisture for a long time even if face washing or wiping is performed after use.

  The application amount of the non-aqueous medium such as massage oil is 25 to 500 parts by weight, preferably 50 to 300 parts by weight with respect to 100 parts by weight of the base sheet. If the amount is less than 25 parts by weight, the effect of continuing the foaming duration due to the application of the non-aqueous medium is small, and it is difficult to prevent the powdery cosmetic and the foaming agent from falling off. In addition, foam inhibition inhibition due to moisture in the surrounding atmosphere is poor. On the other hand, if it exceeds 500 parts by weight, even if water is applied to the resulting sheet, it is difficult for water to penetrate into the sheet, and the foaming of carbon dioxide gas may worsen, and it adheres to the site where the sheet is used. Oil dripping will occur before and after adhering to the skin. In addition, the price for the skin-modifying effect is high, and the effect commensurate with the cost is not preferable.

  In addition, regarding the skin modified sheet of the present invention, in order to compare the rigidity of the sheet, the sheet is cut into a rectangle having a width of 50 mm and a width of 200 mm, and the end portion of the sheet having a width of 50 mm is gradually removed from the end portion of the desk having a right angle surface. When the leading edge of the protruding and protruding sheet reaches 100 mm from the edge of the desk, the bending dimension from the desk smooth surface at the leading edge of the sheet was measured, and the bending dimension 100 of the base sheet before containing the oil component was measured. On the other hand, the bending dimension of the sheet containing the non-aqueous medium is 150 or more, and in an extreme case, the rigidity decreases as it comes into contact with the plane perpendicular to the horizontal plane of the desk, and the flexibility increases. By imparting such flexibility, it is possible to remarkably improve the usability by eliminating the rigidity that becomes a defect of the sheet containing only the powder and improving the adhesion to the place of use.

In addition to the method of squeezing through a pair of rotating rolls, as well as widely used in retort foods, etc., after the skin modified sheet is loaded in a packaging bag, an appropriate amount of massage oil etc. is supplied by a filling nozzle, etc. Appropriate applying means may be used.
Further, in the present invention, “giving” means that a non-aqueous medium such as massage oil is attached to at least the front and back surfaces of the substrate sheet, and the inner layer portion may not be impregnated uniformly. That is, “applying” in the present invention should be interpreted as a means for applying a non-aqueous medium in a broad sense including impregnation and coating.

Specific usage form of skin modification sheet:
When the obtained skin modification sheet of the present invention is used as a face mask for a pack, a plurality of the skin modification sheets may be laminated and punched as shown in FIG. 1 to be used as a face mask. it can. The face mask 10 is formed of the skin modifying sheet of the present invention, and the whole is cut into an approximately oval shape with a size that can cover almost the entire face. When the face mask 10 is placed on the face, an opening 11 is formed in the portion corresponding to both eyes so that the face mask 10 is oblong and cut into an oval shape so as not to block the eyes. Yes. In addition, a portion corresponding to the mouth is also formed with an opening 12 that is horizontally long and oval cut so as not to block the mouth. In addition, a substantially U-shaped cut 13 is formed at the portion corresponding to the nose so as to be turned upward according to the shape of the nose. Further, four cuts 15 are provided on the outer edge 14 of the face mask 10.
When using such a face mask 10, there is a method in which water is attached to the surface of the face mask after the entire face mask 10 is placed on the face. If it does in this way, the sheet | seat which adhered nonaqueous media, such as massage oil, has the advantage of being easy to closely_contact | adhere to the site | part of a face, and can obtain the blood circulation promotion effect by foaming after moisturizing skin with oil. Furthermore, in order to make the effect of the massage oil more effective, it can be said that it is more desirable to wash the face using a facial cleanser before use. By using water or hot water on the face mask that is in close contact with a desired position on the face, moisture gradually permeates the inner layer of the face mask through a non-aqueous medium such as massage oil, and is stored in the inner layer. At the same time as carbon dioxide is generated from the cosmetic, carbon dioxide generated by the action of the foam stabilizer is retained, and the carbon dioxide effect is maintained. At this time, if a pyrogen as described above is contained, the blood circulation state of the face is further promoted. And, the penetration rate of water into cosmetics is slower for those containing non-aqueous media such as massage oil compared to those that do not contain, resulting in longer foaming time and blood circulation on the face The promotion effect will be sustained. Even after the foaming is finished, the oil component and the scent component can be fully enjoyed, and the effect of the oil component and the like can moisturize the dry skin and can fully enjoy the sense that the user is healed. After peeling off the skin-modifying sheet, the face can be washed again or the moist feeling can be adjusted to the user's preference by using a lotion or the like so that the user can have a comfortable condition. At this time, it is desirable not to completely remove the oil component penetrating the skin in order to keep the moisture for a long time.

  EXAMPLES Hereinafter, although an Example is given and this invention is demonstrated further more concretely, this invention is not limited to these Examples.

Example 1 (face mask using a skin modified sheet containing massage oil)
First, a spunlace nonwoven fabric was produced. The raw material fibers are 45% by weight of rayon (made by Ohmi Kenshi Co., Ltd., 2.2 dt × 51 mm), 45% by weight of Tencel (manufactured by Coatles Co., Ltd., 1.7 dtex × 51 mm), and PP (polypropylene) / PE (polyethylene). ) System core-sheath type composite fiber (manufactured by Chisso Corporation, 2.2 dtex × 51 mm) was 10% by weight. From these mixed cotton card webs, a water flow is ejected from a plurality of nozzles having a hole diameter of 0.15 mm at 100 kgf / cm ² to first subject the surface to fiber entanglement treatment, and then apply the same water flow treatment from the opposite surface to produce a fiber entanglement sheet. Further, a spunlace nonwoven fabric with a basis weight of 22 g / m ² was produced by heating with hot air at 135 ° C.
Next, this spunlace nonwoven fabric is used as a carrier sheet, and as an inner layer portion thereon, PET (polyethylene terephthalate) / PE-based heat-bondable core-sheath composite fiber (manufactured by Teijin Fibers Ltd., 2.2 dt × 5 mm, below) the same) 37.5 wt% (15g ^{/ m} 2), comminuted wood pulp (Weyerhaeuser Co., NB416, hereinafter the same) 37.5 wt% (15g ^{/ m} 2), cosmetic powdered following recipe Was mixed to 25 wt% (10 g / m ² ), and a total web layer of 40 g / m ² was formed on the carrier sheet by the airlaid method. Further, a spunlace nonwoven fabric similar to the above was laminated thereon as a surface layer. The sheet consisting of three layers of 84 g / m ² in total was heated in a hot air suction heating furnace at 138 ° C. and integrated. Next, the obtained 0.9 mm thick laminated sheet is punched out as a face mask as shown in FIG. 1 and then passed through an olive squalane (manufactured by MUJI) stored in an oil bath. By liquefying, 100 parts by weight of the sheet was impregnated with 200 parts by weight of this olive squalane.

The oil-containing skin-modified sheet prepared in this way was thoroughly washed with a facial cleanser before use and then used as a pack. The carbon dioxide foaming time was as long as 1 to 10 minutes, and there was a feeling of foaming. The effect was confirmed.
