Description

  The present invention relates to a sheet used for a cosmetic-impregnated mask used by impregnating the cosmetic, and a constitution of the cosmetic-impregnated mask using this sheet.

  2. Description of the Related Art Conventionally, cosmetic impregnation masks that are used by impregnating cosmetics into a sheet body formed of a nonwoven fabric or the like have been widely used. This cosmetic-impregnated mask is intended to obtain a higher beauty effect by covering the face with a sheet body impregnated with the cosmetic for a certain period of time, thereby ensuring that the cosmetic is brought into contact with the user's face. Is.

  And as a sheet | seat main body used for the above cosmetics impregnation masks, what is shown to patent document 1 is well-known. In this prior art, a surface layer containing more than 90 wt% of fibers having a fineness greater than 0.5 dtex is formed on both sides of an intermediate layer containing 50 wt% or more of cellulose short fibers. As described above, by arranging the cellulose-based short fibers as an intermediate layer, the cellulose-based short fibers have high liquid retention, so that the liquid retention of the sheet main body can be improved, and the cosmetic that can be impregnated into the sheet main body. It is possible to increase the amount of cosmetics so that a sufficient amount of cosmetics can be brought into contact with the user's face.

JP 2007-7062 A

  In the sheet main body described in Patent Document 1, the liquid retention is improved by forming an intermediate layer with cellulose-based short fibers as described above. Furthermore, in order to contact a large amount of cosmetics, not only the intermediate layer but also the surface layer in contact with the face portion needs to have high liquid retention.

  In addition, in order to make the cosmetic impregnated in the sheet main body uniformly contact the entire face of the user, it is necessary to fit the sheet main body to the entire face of the user corresponding to the unevenness. For this purpose, the sheet body needs to be stretched along the contoured shape of the user's face, and the sheet body is required to have high stretchability.

  Thus, it is preferable that the surface layer of the sheet body has high liquid retention and extensibility. However, Patent Document 1 does not disclose the combination and mixing ratio of materials forming the surface layer. Therefore, when the liquid retention or stretchability of the surface layer is insufficient, the sheet body cannot be impregnated with a sufficient amount of cosmetic material, and the cosmetic material impregnated in the sheet body is applied to the user's face. It cannot be sufficiently brought into contact.

  Therefore, the present invention is intended to solve the above-described problems, has high liquid retention, impregnates a large amount of cosmetics in the sheet body, and provides a sufficient amount of cosmetics on the user's face. It is possible to make contact. In addition, it has high extensibility, the seat body can be fitted to the entire user's face corresponding to the unevenness, and the cosmetic impregnated in the seat body can be brought into uniform contact with the user's face. It is intended to obtain a cosmetic-impregnated mask.

The present invention is to solve the problems of the above such as the prior art, on both sides of the intermediate layer made of cellulose-based staple fibers, cotton 55wt% ~75wt%, by disposing a surface layer formed of PET25wt% ~45wt% Sheet Forms the body. As a result, the expansion ratio of the sheet body when dry is CD: 20% or less, MD: 10% or less, and the expansion ratio of the sheet body when wet is CD: 45% or more, MD: 10% or more. The saturation liquid retention ratio is 40 wt% or more.

  In the present specification and claims, the dry state means a state in which the water absorption rate of the sheet body is less than 1%. In addition, the wet state refers to a state in which ion exchange water is excessively added and left to be impregnated until saturated. Further, in the present specification and claims, “CD” means a direction (Cross Direction) orthogonal to the flow direction of the production line, and “MD” means a flow direction (Machine Direction) of the production line. Means.

Further , in the present invention , PET is subjected to a hydrophilic treatment with a surfactant, whereby the hydrophilicity of the surface layer is increased, and the cosmetic can be impregnated more rapidly into the sheet body. In addition, the PET treated with the surfactant according to claim 1 is a non-woven fabric formed using the PET, and the non-woven fabric formed by using the birec evaluation method of JIS L 1907 7.1.2 has an MD direction and Polyester fibers that are 10 mm or more in any of the CD directions.

In the present invention , the intermediate layer and the surface layer are integrally formed by causing entanglement of fibers with a water jet in a polymerized state. As described above, the intermediate layer and the surface layer can be reliably bonded by interlacing the fibers with the water jet.

A cosmetic-impregnated mask according to claim 2 is formed using the cosmetic-impregnated mask sheet according to claim 1 .

  As described above, the cosmetic-impregnated mask sheet of the present invention and the cosmetic-impregnated mask using this sheet have an intermediate layer formed of cellulose-based short fibers, and the cellulose-based short fibers have high liquid retention. Therefore, it is possible to impregnate the intermediate layer with a large amount of cosmetic liquid. Therefore, a sufficient amount of cosmetic can be brought into contact with the user's face.

  Further, cotton 55 wt% to 75 wt% and PET 25 wt% to 45 wt% are blended in the surface layer disposed on both surfaces of the intermediate layer. By blending cotton into the surface layer in this way, since cotton has high liquid retention, not only the above-mentioned intermediate layer but also the surface layer can be impregnated with a sufficient amount of cosmetics. A larger amount of the cosmetic liquid can be brought into contact with the face portion.

  Moreover, since the liquid permeability of the surface layer can be improved by blending cotton into the surface layer in this manner, the cosmetics easily pass through the surface layer. Therefore, it is possible to easily infiltrate the cosmetic material from the surface layer to the intermediate layer at the time of manufacture, and it is possible to easily supply the cosmetic material from the intermediate layer to the surface layer at the time of use. It is possible to effectively use the high liquid retention of the intermediate layer as described above for the surface layer.

  Further, the intermediate layer formed of cellulose-based short fibers as described above deteriorates its shape retaining property when impregnated with moisture such as cosmetics, and therefore easily breaks when it is stretched. However, in the present invention, the surface layer contains PET, and since this PET has high extensibility, the surface layer has high extensibility. Therefore, even when the intermediate layer with reduced shape retention as described above breaks when the sheet body is stretched during use, the surface layers disposed on both sides of the intermediate layer stretch without breaking, so the sheet The entire main body can be extended while maintaining its shape. For this reason, it is possible to avoid inconveniences such as the entire sheet main body breaking during use.

  In addition, as described above, the entire sheet body can be stretched while maintaining its shape, so that the sheet body can be fitted to the entire user's face corresponding to the unevenness during use. It becomes. Therefore, the cosmetic impregnated in the sheet main body can be uniformly brought into contact with the entire face of the user.

  The surface layer of the sheet body is made of 55 wt% to 75 wt% cotton and 25 wt% to 45 wt% PET. If the content of cotton is less than 55 wt%, the content of cotton is too small to provide sufficient liquid retention to the surface layer, and a sufficient amount of cosmetic is applied to the user's face. It cannot be brought into contact.

  Moreover, the liquid permeability of the surface layer becomes insufficient, and the cosmetics are difficult to pass through the surface layer. Therefore, penetration of cosmetics from the surface of the sheet main body to the intermediate layer and supply of cosmetics from the intermediate layer to the surface of the sheet main body become difficult, and the high liquid retention of the intermediate layer as described above can be effectively used. It will be impossible. The reason why the upper limit of the PET content is 45 wt% is that when the PET content exceeds 45 wt%, the cotton content is less than 55 wt%.

  If the PET content is less than 25 wt%, the PET content is too low to obtain sufficient stretchability, and the sheet body does not fit the user's face sufficiently. Therefore, the cosmetic cannot be brought into contact with the entire user's face corresponding to the unevenness. The reason why the upper limit of the cotton content is 75 wt% is that when the cotton content exceeds 75 wt%, the PET content is less than 25 wt%.

  In addition, the sheet body has an elongation ratio in the dry state of CD: 20% or less and MD: 10% or less. If the expansion ratio of the sheet body during drying exceeds CD: 20% or MD: 10%, the rigidity of the sheet body during manufacturing will decrease, making the sheet body difficult to mold, and the line speed will increase. May decrease.

  Further, the extension ratio of the sheet body is set to CD: 45% or more and MD: 10% or more when wet. If the stretch rate when wet is less than 45% CD or less than 10% MD, the stretchability during use is too low and it is difficult to stretch the sheet body corresponding to the face of the user. Therefore, the cosmetic cannot be fitted to the entire user's face corresponding to the unevenness.

  Further, the saturated liquid retention rate of the sheet body is set to 40 wt% or more. If the saturated liquid retention rate of the sheet main body is less than 40 wt%, the saturated liquid retention ratio is too low, and it becomes difficult to impregnate the sheet main body with a sufficient amount of cosmetic.

Sectional drawing which shows the structure of a sheet | seat main body. The conceptual diagram which shows the measuring method of a liquid retention. The conceptual diagram which shows the measuring method of an expansion | extension rate. The top view of the cosmetics impregnation mask formed using the sheet | seat for cosmetics impregnation masks of Example 1. FIG.

  The cosmetic impregnated mask sheet of Example 1 will be described in detail below. In addition, about the material of the sheet | seat main body (1) of Example 1 and Comparative Examples 1-9, and the structure of a layer, it is as having shown in Table 1 and FIG.

  First, as shown in Table 1 and FIG. 1, Example 1 has a three-layer structure in which surface layers (3) and (4) formed of a nonwoven fabric are disposed on both sides of the intermediate layer (2). The intermediate layer (2) and the surface layers (3) and (4) are integrally formed by causing entanglement of fibers with a water jet in a polymerized state. Thus, it becomes possible to join the intermediate | middle layer (2) and surface layer (3) (4) reliably by entanglement of fibers using a water jet.

  Moreover, the said intermediate | middle layer (2) consists only of the pulp which is a cellulosic short fiber. The surface layers (3) and (4) are non-woven fabrics as described above, and are composed of 30 wt% PET subjected to hydrophilic treatment and 70 wt% cotton. By using PET that has been subjected to hydrophilic treatment in this manner, the hydrophilicity of the surface layers (3) and (4) can be increased, and the sheet body (1) can be more quickly impregnated with the cosmetic.

  Note that the PET subjected to the above hydrophilic treatment is a non-woven fabric formed using the PET with a suction height of 10 mm or more in both the MD direction and the CD direction according to the JIS L 1907 7.1.2 birec evaluation method. It means the polyester fiber. For example, in the case of PET subjected to hydrophilic treatment (hereinafter referred to as hydrophilic PET) used in this example, hydrophilic PET (fineness 1.3 dtex, fiber length 38 mm) is integrally formed with a water jet to form a nonwoven fabric, When the measurement based on the said JIS specification was performed with respect to this nonwoven fabric, the water absorption height of MD direction was 36 mm, and the water absorption height of CD direction was 30 mm.

  Next, Comparative Examples 1 to 9 will be described below. First, Comparative Examples 1 to 4 have a single-layer structure, unlike Example 1 of the present invention having a three-layer structure. Moreover, the comparative example 1 consists only of cotton and the comparative examples 2-4 mix | blend hydrophilic PET and cotton in a different ratio, and are formed.

  Further, in Comparative Examples 5 to 9, as in Example 1, the intermediate layer is formed with a three-layer structure in which surface layers are formed on both surfaces of the intermediate layer, and the intermediate layer is formed only of pulp. On the other hand, in Comparative Examples 5 to 7, the material forming the surface layer is different from Example 1. That is, in Example 1, as described above, the surface layers (3) and (4) are formed of a nonwoven fabric made of hydrophilic PET and cotton, whereas in Comparative Example 5, the surface layer is formed. It is formed only from cotton, and in Comparative Example 6, the surface layer is formed only from hydrophilic PET. In Comparative Example 7, the surface layer is formed of 30 wt% hydrophilic PET and 70 wt% rayon.

  In Comparative Examples 8 and 9, the surface layer is formed of a nonwoven fabric made of hydrophilic PET and cotton as in Example 1, but the blending ratio is different from that in Example 1. That is, in Example 1, the surface layers (3) and (4) are formed by hydrophilic PET 30 wt% and cotton 70 wt%, but in Comparative Example 8, the surface layer is formed by hydrophilic PET 20 wt% and cotton 80 wt%. In Comparative Example 9, the surface layer is formed of hydrophilic PET 50 wt% and cotton 50 wt%.

And about the sheet | seat main body (1) of Example 1 and Comparative Examples 1-9, experiment for measuring a liquid retention was conducted. The method for measuring the liquid retention rate will be described with reference to FIG. 2. Each of the 50 mm square sheet main bodies (1) formed according to Example 1 and Comparative Examples 1 to 9 is prepared, and the sheet main body (1) is prepared. , Impregnated with ion exchange water at a rate of 0.12 ml per 60 g / m ² . After 1 minute from impregnation with ion-exchanged water, filter paper (No. 2, 90 mm square) (5) (6) is arranged above and below the sheet body (1), and the upper side filter paper (5) A weight (1 kg, 90 mm square on the pressing part) (7) is placed on the top of the pad and weighted for 15 seconds. Then, after the weighting is stopped, the increased weight of the filter paper (5) (6) is measured, and the increase of the filter paper (5) (6) from the weight of the ion exchange water impregnated in the sheet body (1) at the beginning of the experiment. The weight obtained by subtracting the weight is used as the liquid retention amount of the sheet body (1). And the value which divided the liquid retention amount of this sheet | seat main body (1) by the weight of the ion-exchange water which the sheet | seat main body (1) impregnated at the beginning of experiment was evaluated as a liquid retention rate of a sheet | seat main body (1).

  The results of the experiment are shown in Table 1. As can be seen from the experimental results, Example 1 of the present invention has a high liquid retention rate as compared with any sheet body (1) of the comparative example. Therefore, a larger amount of cosmetic can be impregnated, and a sufficient amount of cosmetic can be brought into contact with the user's face during use.

  In addition, with respect to the sheet body (1) of Example 1 and Comparative Examples 1 to 9, experiments were performed to measure the stretch rate at the time of WET and the stretch rate at the time of DRY. The elongation rate was measured for each of CD and MD.

  First, the method for measuring the MD expansion rate will be described with reference to FIG. 3. The sheet body (1) of each of the examples and comparative examples is formed into a rectangular shape having a length in the MD direction of 50 mm and a length in the CD direction of 25 mm. Prepare and fix one end of the sheet body (1) in the MD direction. Then, the other end in the MD direction of the sheet body (1) is pulled in the extension direction as indicated by the arrow in FIG. 3 with a force of 1 Newton, and the extension length at that time is the MD direction length (50 mm). The divided numerical value was evaluated as an extension rate in the MD direction.

  The same applies to the method for measuring the CD expansion ratio. A rectangular sheet body (1) having a length in the CD direction of 50 mm and a length in the MD direction of 25 mm is prepared, and the CD of the sheet body (1) is prepared. Fix one end of the direction. Then, the other end in the CD direction of the sheet body (1) is pulled in the extension direction with a force of 1 Newton, and the value obtained by dividing the extension length at that time by the length in the CD direction (50 mm) is the extension in the CD direction. Rated as a rate.

  The results of the experiment are shown in Table 1. As can be seen from the experimental results, in Example 1 of the present invention, the stretch rate at the time of WET is higher than that of Comparative Examples 1, 5, 7, and 8 for both CD and MD. Therefore, in use, the seat body (1) will fully expand along the contoured shape of the user's face, and the seat body (1) fits the entire face of the user corresponding to the unevenness. Therefore, the cosmetic impregnated in the sheet main body (1) can be brought into contact with the entire face of the user.

  In Comparative Examples 2 and 9, the CD expansion rate at the time of WET is higher than that in Example 1. In Comparative Examples 3, 4 and 6, the expansion rate at the time of WET is an example for both CD and MD. It is higher than 1. This is because the sheet main bodies (1) of Comparative Examples 3, 4, 6, and 9 are blended with a higher proportion of hydrophilic PET having higher extensibility than that of Example 1, and the sheets of Comparative Examples 2 to 4 This is probably because the main body (1) does not have a pulp layer with low extensibility. However, the sheet main bodies (1) of Comparative Examples 2 to 4, 6, and 9 are all inferior to those of Example 1 in the liquid retention rate. On the other hand, the sheet body (1) of the present embodiment has a high liquid retention rate while maintaining a high extension rate at the time of WET.

  Further, the sheet main body (1) of Example 1 has the same stretch ratio as that of Comparative Examples 2, 3, 6, 7, and 9 for both CD and MD, or lower than those of Comparative Examples. Yes. As described above, the sheet main body (1) of the present embodiment has a low expansion rate during DRY for both CD and MD, and therefore the rigidity of the sheet main body (1) at the time of manufacture is high. The molding work becomes easy and the line speed can be increased.

  In Comparative Example 1, the CD expansion rate during DRY is lower than that in Example 1, and in Comparative Examples 4, 5, and 8, the MD expansion rate during DRY is lower than that in Example 1. It has become a thing. However, all of the sheet main bodies (1) of Comparative Examples 1, 4, 5, and 8 are significantly inferior to Example 1 in the liquid retention rate. Compared with the sheet body (1) of Comparative Examples 1, 4, 5, and 8, the increase in the elongation rate during DRY of the sheet body (1) of this example is slight, but high. It has a liquid ratio.

  A cosmetic impregnated mask using the cosmetic impregnated mask sheet of Example 1 will be described below with reference to FIG. For convenience of explanation, terms such as an upper end and a lower end are used with reference to FIG.

  First, the mask body (8) formed by using the cosmetic-impregnated mask sheet has an area that can roughly cover the human face surface, and a pair of eye notch portions ( 10) is provided in an inverted U-shape, and the inner portion of the eye cut portion (10) is a folded piece (11) that can be folded downward. When the mask is used, the folded piece (11) is folded downward to form an opening at a position corresponding to the user's eye so that the user's field of view is not blocked. It is also possible to cover the eye with the folded piece (11) in a state where the user opens his eyes, and to attach the cosmetic to the eyelid.

  Further, two upper notch portions (12) are formed above the pair of eye notch portions (10) along the upper edge of the mask body (8). Further, on both sides of the pair of eye cuts (10), two double cuts (13) are formed along both side edges of the mask body (8). Thus, by providing the upper notch portion (12) and the both side notch portions (13), the mask body (8) can be easily made to correspond to the three-dimensional shape of the forehead and cheeks of the user. It becomes possible to enhance the fit of the mask body (8) to the face.

  Moreover, the both side protrusion part (14) is formed above the said both side notch part (13). By forming the both side protrusions (14) in this way, when the user uses the mask, the both sides of the protrusions (14) can be grasped with both hands, so that the mask body (8) can be easily expanded. It can be used.

  Further, the mask body (8) is provided with a nasal notch (15) corresponding to the shape of the nose below the eye notch (10). The nasal notch ( The inner part of 15) is a raised piece (16) that can be raised from the mask body (8). When the mask is used, the raised piece (16) is raised corresponding to the user's nose, and the fit of the mask body (8) to the user's nose can be enhanced. . Moreover, since an opening part will be formed in the position corresponding to a user's nostril with the protrusion of the above-mentioned protruding piece (16), it will become easy for a user to breathe.

  Further, the mask body (8) is provided with a mouth opening (17) below the nasal cut portion (15) so that the user can easily breathe. On both sides of the mouth opening (17), a mouth notch (18) is provided. Thus, by providing the notch part (18) for mouth parts, it can respond to the difference in the dimension of a user's mouth part.

  In addition, a total of three notch portions (20) for the chin portion are provided at the lower end of the mask body (8) at the center and the left and right. In this way, by forming the notch portion (20) for the jaw portion, the plurality of jaw covering pieces (21) are formed, the mask body (8) is made to correspond to the raised shape of the user's jaw portion, The lower surface can be covered with the jaw covering piece (21), and the fit of the mask body (8) to the user's jaw can be enhanced.

  In addition, in order to make the mask main body (8) fit well on the face surface, high extensibility is required in the left-right direction of the mask main body (8). Therefore, as in the case of the first embodiment, when the expansion ratio in the CD direction when the sheet body (1) is wet is higher than the expansion ratio in the MD direction, the horizontal direction of the mask body (8) is set in the CD direction. To correspond to. On the other hand, when the expansion ratio when the sheet body (1) is wet in the MD direction is higher than the expansion ratio in the CD direction, the left-right direction of the mask body (8) is made to correspond to the MD direction. In short, it is preferable to provide higher extensibility in the left-right direction of the mask body (8).
