Description

  The present invention relates to a cosmetic puff used, for example, when putting an emulsion on the skin, and a method for producing the same.

  When applying liquid cosmetics such as lotion or milky lotion to the skin, these cosmetics are absorbed into the cosmetic puff, and then the cosmetic puff is put on the skin, and the cosmetic in the cosmetic puff is then removed from the skin. It is generally done to migrate to. As such a cosmetic puff, conventionally, 100% cotton made of cotton fibers has been widely used.

However, cosmetic puffs made of natural fibers, such as cotton fibers, can be used without any problems when putting in lotion. Then, the following problems occurred.
That is, since the natural fiber has a small fiber diameter, the pore size in the cosmetic puff made of natural fiber is also small. For this reason, such a cosmetic puff has a large resistance when sucking a high-viscosity emulsion, and is hardly absorbed just by dropping the emulsion onto the cosmetic puff. In addition, even after the emulsion is dripped into the cosmetic puff, the emulsion is absorbed into the emulsion and the cosmetic puff. Affinity with the emulsion was difficult to release, and the emulsion remained in the cosmetic puff and was likely to be wasted. Moreover, such a cosmetic puff is made of natural fibers that do not have a waist, and since the natural fibers are not bonded to each other in the puff, There was also a drawback that the puff was crushed and it was easy to lose its shape.

Therefore, in place of such a cosmetic puff made of natural fibers, it has been studied to use a hydrophobic synthetic fiber as a raw material and a nonwoven fabric obtained by a carding method (dry method) as a cosmetic puff.
For example, Patent Document 1 discloses a card web obtained by using polypropylene composite fiber having a fiber length of about several tens of millimeters having three-dimensional crimps and rayon fiber as raw fibers and passing the raw fibers through a parallel card. The use as a cosmetic puff is described. In Patent Document 2, a card web is manufactured from a raw material fiber made of polyester-based short fibers having a fiber length of about several tens of mm and cotton, heat-treated, and the resulting nonwoven fabric is used as an inner layer. The puff for is described.

  However, the cosmetic puffs described in these patent documents also have insufficient liquid absorbency when putting on a skin containing an emulsion having a viscosity higher than that of the lotion.

It is a longitudinal section showing an example of a makeup puff. It is a graph which shows the result of evaluation B in an example.

Hereinafter, the present invention will be described in detail.
<Cosmetic puff>
FIG. 1 is a longitudinal sectional view showing the configuration of a cosmetic puff according to the present invention.
This cosmetic puff is composed of a nonwoven fabric laminate 13 in which a surface layer 12 made of a nonwoven fabric (B) is provided on both surfaces of an intermediate layer 11 made of a nonwoven fabric (A).

[Middle layer (nonwoven fabric (A))]
The nonwoven fabric (A) constituting the middle layer 11 is obtained by heat-treating an airlaid web formed from raw fibers mainly composed of latent crimped synthetic fibers and heat-fusible synthetic fibers.
Nonwoven fabrics are generally manufactured through a web forming step in which raw material fibers are laminated to form a sheet-like web, and a fiber bonding step in which raw material fibers in the obtained web are bonded.
The nonwoven fabric (A) used in the present invention is bonded between fibers by melting the heat-fusible synthetic fiber in the air-laid web by heat treatment to the air-laid web obtained by adopting the air-laid method as a web forming process. The so-called thermal bond method for forming the film is employed as the fiber bonding step. The airlaid method is a web forming method in which raw fibers are randomly laminated three-dimensionally using an air flow. By adopting the airlaid method, it exhibits high liquid absorbency and liquid release properties even for high-viscosity emulsions (for example, viscosity at 25 ° C .: about 3000 to 5000 mPa · s). And the nonwoven fabric (A) which is hard to lose a shape also when using continuously by repeating putting can be manufactured.
Further, in the fiber bonding step, a method using a latex bond method in combination with a thermal bond method (multi-bond method) can be employed. The latex bond method is a method of bonding raw fibers in a web with an adhesive, and an emulsion adhesive is often used. There are a spray method and a dipping method for adding the adhesive.

  The latent crimped synthetic fiber used for the production of the nonwoven fabric (A) is a synthetic fiber in which crimps (crimps, curls, spirals) are manifested by heat treatment. For example, resins having different shrinkage ratios upon heating by heat treatment are used. Examples thereof include a synthetic fiber having a side-by-side structure obtained by combining and an eccentric core-sheath structure. Here, if a crimped synthetic fiber (non-latent crimp type) that originally has crimps but does not manifest crimps by heat treatment, the airlaid web obtained becomes bulky immediately after its formation. Even after that, by receiving shares in various processes until the cosmetic puff is obtained, the bulk tends to be lowered eventually, and the touch is also inferior. On the other hand, when using latently crimped synthetic fibers in which crimps are manifested by heat treatment, crimps are manifested during the fiber bonding step in which heat treatment is performed on airlaid webs. A) can be obtained. In addition, before and after the fiber bonding step, a heat treatment step may be separately provided in order to reveal the crimp of the latent crimp synthetic fiber.

  The latent crimped synthetic fiber may or may not have a mild crimp even in a state before the heat treatment.

The latent crimped synthetic fiber is selected from the group consisting of polyethylene terephthalate (PET), polyethylene (PE), and polypropylene (PP), from the viewpoint of obtaining a nonwoven fabric (A) having high hydrophobicity and excellent liquid release properties. Adopt one made of more than seed resin. Specifically, a latent crimped synthetic fiber (PET / PET composite fiber, PE / PE composite fiber, PP / PE) having a side-by-side structure or an eccentric core-sheath structure in which two kinds of resins having different shrinkage ratios upon heating are combined. PP composite fiber, PE / PET composite fiber, PP / PET composite fiber, PE / PP composite fiber).
In addition, as the resin of the latent crimped synthetic fiber, a resin having a melting point that does not melt at the heat treatment temperature when the heat-fusable synthetic fiber in the air laid web is melted to form a bond between the fibers is adopted.
From this point of view, the latent crimped synthetic fiber is a latent crimped synthetic fiber (PET / PET composite fiber) having a side-by-side type structure or an eccentric core-sheath type structure in which two types of PET having different shrinkage ratios upon heating are combined. ) Is preferable because of its high melting point and excellent heat resistance when the air-laid web is heat-treated.

The heat-fusible synthetic fiber used for the production of the nonwoven fabric (A) melts at least partly by heat treatment in the fiber bonding step, and acts as a binder. From the point which can obtain the outstanding nonwoven fabric (A), what consists of 1 or more types of resin chosen from the group which consists of polyethylene terephthalate (PET), polyethylene (PE), and polypropylene (PP) is employ | adopted.
Further, as the heat-fusible synthetic fiber, a heat-fusible composite synthetic fiber having a core-sheath structure obtained by combining two kinds of resins having different melting points and melting only the surface of the fiber is preferable. The heat-sealable composite synthetic fiber having a core-sheath structure has a structure in which a sheath made of a resin having a low melting point is formed on the outer periphery of a core made of a resin having a high melting point. The form which combined 2 types of resin (PET / PET composite fiber, PE / PE composite fiber, PP / PP composite fiber, PE / PET composite fiber, PP / PET composite fiber, PE / PP composite fiber) is mentioned. Among these, PE / PET composite fiber, PET / PET composite fiber in which a sheath made of low-polymerization PET having a lower melting point than PET is formed on the outer periphery of a core made of high-polymerization PET, etc. Is preferred.

  The fiber length of the latent crimped synthetic fiber and the heat-fusible synthetic fiber is preferably 2 to 20 mm, more preferably 2 to 10 mm, and further preferably 2 to 6 mm. With such a fiber length, when forming an air laid web by the air laid method, these fibers are randomly laminated three-dimensionally, and as a result, they are excellent in bulky and high viscosity emulsions. It becomes a nonwoven fabric (A) that exhibits liquid absorbency and liquid release properties and is not easily deformed when continuously used as a cosmetic puff. If the fiber length exceeds the upper limit of this range, the fiber length is too long, so even if it is subjected to the airlaid method, most of the fibers are oriented two-dimensionally along the plane of the web. It becomes difficult to laminate. In that case, the obtained non-woven fabric (A) is low in volume, and therefore, the liquid-absorbing property with respect to a particularly high-viscosity emulsion is insufficient and the shape tends to be easily lost. On the other hand, if it is less than the lower limit, the fibers become dense in the non-woven fabric (A), the liquid absorbency decreases, the touch when touching the skin becomes hard, and there is a tendency that a tingling sensation occurs.

  The fiber diameter of the latent crimped synthetic fiber and the heat-fusible synthetic fiber is preferably 0.5 to 20 dtex, more preferably 0.5 to 3 dtex, and still more preferably 1 to 2.5 dtex. With such a fiber diameter, the nonwoven fabric (A) having excellent liquid absorbency can be obtained. Moreover, the bulk of the nonwoven fabric (A) is moderate and excellent in touch. When the fiber diameter exceeds the upper limit of this range, a bulky nonwoven fabric (A) can be obtained, but the pore size becomes too large, the capillary force is reduced, the liquid absorbency is lowered, and the fiber itself is rigid. The tingling sensation increases and the touch becomes worse. On the other hand, when the fiber diameter is less than the lower limit of this range, the capillary size increases because the pore size decreases. However, the resistance when sucking a high-viscosity emulsion is increased, and the space (pore) for holding the sucked liquid is also small. As a result, the liquid absorbability tends to be inferior. Moreover, there exists a tendency for the bulk to become small and the touch when touching the skin becomes hard.

  In the present specification, the fiber diameter is expressed in the unit “dtex (decitex)”. 1 dtex is the thickness of a thread having a length of 10,000 m and a weight of 1 g. The fiber length is an average value of lengths measured by observation with an electron microscope using 50 or more arbitrarily selected fibers as samples.

  The raw material fibers used for the production of the nonwoven fabric (A) are mainly composed of the above-described latent crimped synthetic fibers and heat-fusible synthetic fibers. A main component here is a component which occupies 95 mass% or more in raw material fiber. That is, the raw fiber used for manufacturing the nonwoven fabric (A) contains the latent crimped synthetic fiber and the heat-fusible synthetic fiber in a total of 95% by mass or more. For the raw material fiber, for example, for the purpose of finely adjusting the liquid absorbency and liquid discharge property of the nonwoven fabric (A), the fiber other than the latent crimp synthetic fiber and the heat-fusible synthetic fiber is 5% by mass or less. It may be included in the range. Examples of such fibers include natural fibers such as pulp fibers and cotton fibers. Further, synthetic fiber other than the above-described latent crimped synthetic fiber and heat-fusible synthetic fiber may be included.

For example, examples of the pulp fiber include wood pulp (conifers, hardwoods), rug pulp, linter pulp, linen pulp, non-wood pulp such as straw, three bases, and husk pulp, and raw pulp such as waste paper pulp. As the raw material pulp, any of mechanical pulp (GP, RGP, TMP, etc.) and chemical pulp (sulfite pulp, kraft pulp, etc.) can be used. Among these, kraft pulp is preferable from the viewpoints of supply amount, quality stability, cost, and the like.
Moreover, as a pulp fiber, it is preferable to use a short fiber having a length-weighted average fiber length (measured by a fiber length measuring device FS-200 (manufactured by Kajaani Co.)) of preferably 10 mm or less, more preferably 6 mm or less. .

  The ratio of the latently crimped synthetic fiber and the heat-fusible synthetic fiber in the raw fiber is such that the total of the latent-crimped synthetic fiber and the heat-fusable synthetic fiber is 100% by mass. Is 20 to 70% by mass, the heat-fusible synthetic fiber is preferably 30 to 80% by mass, the latent crimped synthetic fiber is 40 to 60% by mass, and the heat-fusible synthetic fiber is 60 to 60% by mass. More preferably, it is 40 mass%. By setting the ratio of the latent crimped synthetic fiber to the lower limit value or more of the above range, the bulk of the nonwoven fabric (A) is sufficiently increased, and therefore has excellent liquid absorbency and liquid release properties even for high viscosity emulsions. It is easy to obtain a cosmetic puff that is expressed, hardly loses its shape, and does not become hard to the touch. On the other hand, by setting the proportion of the latent crimped synthetic fiber to be equal to or less than the upper limit of the above range, the proportion of the heat-fusible fiber is relatively increased, and the fiber is sufficiently bonded and used as a cosmetic puff. Dropout tends to be suppressed.

As a bulk (density) of a nonwoven fabric (A), 0.01-0.05 g / cm < ³ > is preferable, More preferably, it is 0.01-0.03 g / cm < ³ >. With such a bulk, better liquid-absorbing properties, liquid-releasing properties, and difficulty in losing shape are exhibited. In this specification, the bulk is measured by a TECLOCK constant pressure thickness measuring instrument, PG-02, under an 8 g / cm ² load condition.
Moreover, it is preferable that thickness is 2-6 mm and basic weight is 60-120 g / m < ² >, If it is this range, while being able to obtain sufficient liquid absorptivity, it is easier to handle as a cosmetic puff.

[Surface layer (nonwoven fabric (B))]
The surface layer 12 which consists of a nonwoven fabric (B) is provided in both surfaces of the middle layer 11 which consists of a nonwoven fabric (A) mentioned above. Since the nonwoven fabric (A) is manufactured through the airlaid method, the raw fibers are randomly oriented three-dimensionally in the nonwoven fabric (A). Therefore, when the non-woven fabric (A) is used alone as a cosmetic puff as it is, the fiber ends located on the surface of the non-woven fabric (A) touch the skin and feel a tingling feeling. Therefore, by disposing the non-woven fabric (B) as the surface layer 12 and covering the middle layer 11, a tactile sensation is suppressed and a cosmetic puff having a good touch can be obtained.

  As described above, the nonwoven fabric is generally manufactured through a web forming process in which raw fibers are laminated to form a sheet-shaped web, and a fiber bonding process in which the raw fibers in the obtained web are bonded. As the nonwoven fabric (B) used in the cosmetic puff of the present invention, any nonwoven fabric produced through any web forming process and fiber bonding process can be used. For example, a thermoplastic resin is melted and discharged into a fiber shape, and the discharged long fibers are overlapped to form a web (web forming step), and then the web is heated with a hot roll or the like, The nonwoven fabric obtained by the manufacturing method which heat-seal | fuses (fiber bonding process), the nonwoven fabric by what is called a spunbond method, etc. can also be used. However, in terms of texture, touch, etc., the web is formed by using a carding method (web formation process) or the like that provides a soft web as the web formation process, and then the web is heat treated. Nonwoven fabrics that employ a bonding method other than bonding by thermal bonding (thermal bonding method) or bonding by adhesive (chemical bonding method) as the fiber bonding step are preferred. Specific examples of such a fiber bonding step include a spunlace method and a needle punch method.

  When a method of bonding fibers by heat treatment or a method of bonding fibers using an adhesive is adopted as the fiber bonding step, the obtained nonwoven fabric (B) tends to have a hard texture and a loose touch. . On the other hand, as a fiber bonding process, a spunlace method in which a high-pressure water stream is jetted from a nozzle to a web placed on a net (such as a wire net) and the fibers are entangled with each other, or a needle with a stab is pierced into the web. The nonwoven fabric (B) obtained by adopting a needle punch method that mechanically entangles fibers is excellent in the touch and is therefore suitable for use on the surface layer 12.

  Nonwoven fabrics in which raw fibers are bonded by a spunlace method or a needle punch method include a type with large pores and a type with fine pores. Here, when the nonwoven fabric (B) having large pores is used for the surface layer, the raw material fibers in the nonwoven fabric (A) may protrude from the pores of the nonwoven fabric (B), and the touch may be lowered. From this point, the nonwoven fabric (B) is preferably a type having small pores.

In the case of the nonwoven fabric (B) manufactured through the spunlace method, the size of the pores depends on the number of meshes of the net that supports the web when jetting the high-pressure water flow, and the nonwoven fabric (B ), The size of the eye hole depends on the diameter of the needle. In addition, the size of the pores of the nonwoven fabric (B) that has undergone the needle punch method is generally smaller than the size of the pores of the nonwoven fabric (B) that has undergone the spunlace method, and therefore, the nonwoven fabric (B) that has undergone the needle punch method. When viewed with the naked eye, it may appear that no through-holes are formed.
In the case of the non-woven fabric (B) manufactured through the spunlace method, it is preferable to use a non-woven fabric which is manufactured using a net having a mesh number in the range of 50 to 150 mesh and is called a plain type or the like. The number of meshes is the number of wires constituting a net per inch, and the larger the number of meshes (the more the number of wires), the smaller the eye holes. A more preferable net mesh number is 70 to 130, and a more preferable mesh number is 80 to 100 mesh. When the number of meshes of the net is equal to or greater than the lower limit of the above range, the raw material fibers in the nonwoven fabric (A) are unlikely to protrude from the pores of the obtained nonwoven fabric (B), and the touch becomes better. If the number of meshes is not more than the upper limit of the above range, the non-woven fabric (B) does not inhibit the absorption and release of the emulsion because the pores are not too small.

  In the fiber bonding step of the nonwoven fabric (B), a preliminary bonding step such as spraying a small amount of adhesive on the web may be performed before the spunlace method or the needle punch method is employed.

  As a material of the raw material fiber of the nonwoven fabric (B), for example, rayon, lyocell, acrylic, PET, PP, PE / PET are preferable. Even if the raw material fiber composed of one of these is used alone, two or more types are used. The raw material fibers may be used in combination. Among these, rayon is preferable because a nonwoven fabric (B) having a good touch can be easily obtained. The fiber diameter and fiber length of the raw fiber can be appropriately set within the range generally employed in the production of nonwoven fabrics.

As a bulk (density) of a nonwoven fabric (B), 0.01-0.10 g / cm < ³ > is preferable. Moreover, it is preferable that thickness is 0.5-2 mm and basic weight is 20-40 g / m < ² >. If it is such a range, it is preferable in terms of touch and waist (hardness).

The surface layer 12 which consists of a nonwoven fabric (B) is provided in both surfaces of the middle layer 11 which consists of a nonwoven fabric (A). At that time, the middle layer 11 and the surface layer 12 are bonded by, for example, an adhesive. As the adhesive, a substance that exhibits an adhesive action by heat fusion (hot melt adhesive; heat-fusible substance such as PE powder) is used. The usage-amount of an adhesive agent is 3-15 g / m < ² >, for example. Alternatively, it may be fused by the action of the heat-fusible synthetic fiber.
In addition, the method of forming the surface layer 12 on both surfaces of the middle layer 11 by forming a nonwoven fabric (B) in a bag shape and inserting the middle layer which consists of a nonwoven fabric (A) in it, etc. are mentioned, for example.
The nonwoven fabric laminate 13 thus obtained is used for the cosmetic puff of the present invention.

<Method for producing cosmetic puff>
Next, a method for producing a cosmetic puff will be specifically described with an example.
First, the nonwoven fabric (B) which comprises the surface layer 11 is prepared, and the manufactured nonwoven fabric (B) is drawn | fed out on the mesh-like endless belt which is mounted | worn with a conveyor and drive | works.
Next, an adhesive made of PE powder or the like is spread on the nonwoven fabric (B), and then the latent crimped synthetic fiber constituting the raw fiber and the heat-fusible synthetic are formed using an airlaid web forming machine. While mixing the fibers uniformly in the air, they are lowered along with the intake air flow toward the mesh endless belt, and dropped and deposited on the nonwoven fabric (B). Thereby, the air laid web which consists of raw material fibers is formed on a nonwoven fabric (B) (web formation process of a nonwoven fabric (A)).
Thereafter, an adhesive made of PE powder or the like is sprayed on the air laid web, and then the non-woven fabric (B) is laminated to obtain a laminated web in which the surface layer 11 made of the non-woven fabric (B) is provided on both surfaces of the air laid web. .

Next, the laminated web is preferably heat-treated by an air-through method, which is a kind of thermal bond method, to express the crimpability of the latent crimped synthetic fiber, and the non-woven fabric (A) is made of the heat-fusible synthetic fiber. The raw fibers constituting the air laid web are bonded in a bulky state to form the intermediate layer 11 made of the nonwoven fabric (A) (fiber bonding step of the nonwoven fabric (A)). At the same time, the non-woven fabric (A) and the non-woven fabric (B) as the surface layer 12 can be bonded. As a result, a nonwoven fabric laminate 13 is obtained in which the surface layer 12 made of the nonwoven fabric (B) is laminated on both surfaces of the intermediate layer 11 made of the nonwoven fabric (A) via an adhesive.
As the air-through method, a method in which the laminated web is heat-treated by passing through a through-air dryer having a rotating drum having air permeability on the peripheral surface (hot air circulation rotary drum method), or the laminated web uses hot air to laminate the laminated web. A method (hot air circulation conveyor oven method) in which heat treatment is performed by passing through a box-type dryer that can be passed through is preferable.
Here, the nonwoven fabric (A) and the nonwoven fabric (B) may be fused (adhered) by melting the heat-fusible synthetic fibers constituting the nonwoven fabric (A). From the viewpoint of sufficiently obtaining the adhesive strength with (B) and being excellent in practicality as a cosmetic puff, it is preferable to use an adhesive made of PE powder or the like as described above.
In addition, after passing through a rotating drum of a through air dryer or a box type dryer, pressing can be performed as necessary for the purpose of improving surface properties, but if the press pressure is too high, the nonwoven fabric (A) is crushed. Therefore, care must be taken because the bulky middle layer 11 cannot be obtained.

The bulk (density) of the nonwoven fabric laminate 13 is preferably 0.02 to 0.06 g / cm ³ , the thickness is preferably ³ to 5 mm, and the basis weight is preferably 100 to 220 g / m ² .

As described above, the cosmetic puff of the present invention includes, as the middle layer 11, a bulky nonwoven fabric (A) obtained by heat-treating an airlaid web in which raw material fibers are randomly layered three-dimensionally. Therefore, it exhibits excellent liquid absorbency even for a high viscosity emulsion having a large resistance at the time of liquid absorption, and it is difficult to lose its shape even when continuously used. Here, if the middle layer is a non-woven fabric manufactured through the carding method, the non-woven fabric has a low volume, and therefore cannot absorb a high-viscosity emulsion sufficiently. In addition, it is very hard and is not suitable for cosmetic puffs.
Moreover, since the fiber which consists of highly hydrophobic resin is used as a raw material fiber of a nonwoven fabric (A), it is excellent in the liquid release property after absorbing the emulsion which is an oil-in-water emulsion. Moreover, since this cosmetic puff is equipped with the surface layer 12 which consists of a nonwoven fabric (B) on both surfaces of the middle layer 11 which consists of a nonwoven fabric (A), the fiber terminal located on the surface of a nonwoven fabric (A) touches skin directly. There is nothing and it is excellent in the touch.

  As described above, the cosmetic puff of the present invention is suitably used for applications in which the emulsion is applied to the skin. However, the cosmetic puff is not limited to the emulsion. For example, in addition to normal lotion, functionality such as antiperspirant and aroma. It can also be used with a lotion containing the ingredients.

EXAMPLES Hereinafter, although an Example is given and this invention is demonstrated more concretely, this invention is not limited to these Examples.
[Example 1]

This non-woven fabric is a non-woven fabric in which raw fibers are entangled by a high-pressure water stream on a 90-mesh net.
Next, 8 g / m ² of PE powder serving as an adhesive is spread on the nonwoven fabric (B), and then the latent crimped synthetic fiber (1) (trade name: C81, manufactured by Unitika Ltd., fiber length 5 mm, fineness 2.2 dtex, PET / PET composite fiber) and heat-fusible synthetic fiber (1) (trade name: ETC, manufactured by Chisso Corporation, fiber length 5 mm, fineness 1. 7 dtex, PE / PET composite fiber) is uniformly mixed in the air at a mass ratio of 50:50, and is lowered along with the intake air flow to the mesh endless belt side to be dropped and deposited on the nonwoven fabric (B). An air laid web to be A) was formed on the nonwoven fabric (B).

After that, 8 g / m ² of the same adhesive as that used earlier was sprayed on the air laid web, and then a nonwoven fabric made of rayon by the same spunlace method as that used earlier was laminated as the nonwoven fabric (B). A laminated web having a surface layer made of a nonwoven fabric (B) on both surfaces of an airlaid web was obtained.

Each evaluation revealed the following.
The cosmetic puffs of Examples 1 to 4 sufficiently absorbed a high-viscosity emulsion and also had excellent liquid release properties. Other evaluations were also good results. Among these, in Example 2, since the amount of the heat-fusible synthetic fiber constituting the nonwoven fabric (A) was larger than that in Example 1, the cosmetic puff was somewhat hard and stiff. On the other hand, in Example 3, since the amount of the heat-fusible synthetic fiber constituting the nonwoven fabric (A) was small, the amount of fiber dropping slightly increased. In Example 4, since a fiber having a large fiber diameter was used as the latent crimp synthetic fiber and the heat-fusible synthetic fiber, the rigidity of the fiber increased and the touch slightly decreased.
As for “feel”, it has been confirmed that the same evaluation result can be obtained even when lotion is included in the cosmetic puff.

  In Example 5 in which a nonwoven fabric by needle punching was used as the nonwoven fabric (B), the nonwoven fabric had a small through-hole (opening), and thus its liquid release property was lower than that in Example 1. In Example 6 in which the pores of the nonwoven fabric (B) were large, the liquid release property was improved, but the fiber end of the nonwoven fabric (A) protruded from the pores, so that the touch was slightly lowered. In Example 7 where the pores were small, the surface of the nonwoven fabric (B) was smooth and the touch was good, but the liquid release property was slightly lowered. In Example 8 provided with the nonwoven fabric (B) by the spunbond method using an adhesive, the touch was somewhat hard.

  In Comparative Example 1 using a 100% cotton non-woven fabric, the emulsion absorbability was inferior and the shape loss was large. In Comparative Example 2 in which the nonwoven fabric (A) was composed only of the heat-fusible synthetic fibers, the emulsion was hardly absorbed, and therefore the liquid release property could not be evaluated. Moreover, in Comparative Examples 3 and 5-7 using non-latent crimped synthetic fibers instead of latent crimped synthetic fibers, the bulk of the cosmetic puff was low and the liquid release property was inferior, and the touch and texture were also lowered. In Comparative Example 4 in which pulp fibers were used in combination with the nonwoven fabric (A), the liquid absorbency was very good due to the hydrophilicity of the pulp fibers, but the liquid release properties deteriorated. Also, the loss of shape has increased.

(Evaluation B)
For each cosmetic puff of Example 1, Comparative Example 1, and Comparative Example 4, the following experiment was conducted to evaluate the ease of release of the emulsion when the putting was repeated.
Specifically, a cosmetic puff was placed on the filter paper, and 2 g of a commercially available emulsion was dropped onto the surface of the cosmetic puff. Then, after performing an operation of folding the puff into two with the surface on which the emulsion was dropped inside, a filter paper was placed, and both sides of the cosmetic puff were sandwiched by the filter paper. Subsequently, a weight was placed on one surface of the cosmetic puff, a load of about 63 g / cm ² was applied for 90 seconds, and then the weight was removed. Then, the emulsion residual rate (%) was calculated by dividing the mass of the emulsion remaining in the puff by the initial amount of milk droplets (2 g). Thus, after removing the weight, it was removed, and the operation of calculating the latex remaining rate (%) was repeated a plurality of times, and the latex remaining rate (%) was plotted for each time (FIG. 2).
As can be understood from FIG. 2, the cosmetic puffs of Comparative Examples 1 and 4 have a small amount of emulsion released each time, and after 5 or 6 operations, the emulsion remains in the cosmetic puff. Despite this, it became difficult to release the emulsion. On the other hand, the cosmetic puff of Example 1 had a large amount of emulsion released each time, and continued to release the emulsion sufficiently even after 5 or 6 operations. From this, it was found that the cosmetic puff of Example 1 was suitable for continuous use in which putting was repeated. Further, the cosmetic puff of Example 1 was not easily deformed.
