Description

[Technical Field]

[0001] The present disclosure relates to absorbent articles. [Background technology]

[0002] Users of absorbent articles such as light incontinence pads may not be able to change the absorbent article immediately after urination. For this reason, absorbent articles are required to have a function to prevent urine odor, and various deodorizing functions have been investigated.

[0003] For example, Patent Document 1 discloses an absorbent article using an absorbent body containing absorbent resin particles containing a crosslinked polymer having a water-soluble vinyl monomer and / or a hydrolyzable vinyl monomer and a crosslinking agent as essential constituent units, a deodorizing substance, and a fibrous material.

[0004] Furthermore, Patent Document 2 discloses an aromatic composition that can continuously mask the urine odor.

[0005] Patent Document 3 discloses an absorbent article in which a fragrance bag is disposed between a top sheet and an absorbent body. The fragrance bag contains a fragrance material, which is a pulp-based sheet impregnated with a fragrance component, inside a bag body formed into a bag shape using a water-soluble film, and a perforated film with holes formed therein is laminated on the surface of the bag body facing the absorbent body. [Prior art documents] [Patent documents]

[0006] [Patent Document 1] Japanese Patent Application Laid-Open No. 2012-012455 [Patent Document 2] Japanese Patent Application Publication No. 2019-005262 [Patent Document 3] Japanese Patent Publication No. 2022-131483 Summary of the Invention [Problem to be solved by the invention]

[0007] Deodorizing with superabsorbent polymers (SAPs) such as those in the absorbent article described in Patent Document 1 is effective to a certain extent against urine absorbed by the SAP. However, because it takes time for urine to be absorbed by the SAP, it also takes a long time for the deodorizing effect to appear, and the deodorizing effect is low against urine that remains on fluff pulp, nonwoven fabric, or other materials other than the SAP.

[0008] There is also a deodorizing method that uses a masking fragrance, as described in Patent Document 2, but this has problems such as the fragrance volatilizing over long-term storage, reducing the deodorizing effect, and the fragrance smelling constantly while the absorbent article is being worn.

[0009] Furthermore, in absorbent articles such as those described in Patent Document 3, the structure of the scent bag is complex, which may increase manufacturing costs and reduce productivity. Furthermore, since the scent material is a pulp-based sheet impregnated with scent components, the scent components may be firmly adsorbed by the pulp over long-term storage, which may prevent the scent from being felt immediately after urination.

[0010] Therefore, the present disclosure aims to provide an absorbent article with excellent deodorizing performance that is less likely to lose its deodorizing effect due to the fragrance volatilizing during storage, or to have a constant scent of fragrance while being worn, and that can exhibit a deodorizing effect in a short time after absorbing body fluids. [Means for solving the problem]

[0011] In order to solve the above problems, a first aspect of the present invention is an absorbent article comprising a liquid-permeable top sheet on the skin side, a liquid-impermeable back sheet on the non-skin side, and an absorbent body disposed between the top sheet and the back sheet, and further comprising a powdered fragrance contained in the absorbent body or disposed in close proximity to the absorbent body.

[0012] A second aspect of the present invention is an absorbent article according to the first aspect, wherein the absorbent body comprises fluff pulp and a highly absorbent polymer, and the powdered fragrance is disposed on the non-skin side of the absorbent body.

[0013] A third aspect of the present invention is an absorbent article according to the first or second aspect, which comprises a sheet that sandwiches the powdery flavoring.

[0014] A fourth aspect of the present invention is an absorbent article of the third aspect described above, wherein the sheet has a first sheet located on the skin side of the powder fragrance and a second sheet located on the non-skin side of the powder fragrance, and the first sheet is water-soluble. [Effects of the Invention]

[0015] According to the present disclosure, it is possible to provide an absorbent article with excellent deodorizing performance that is less likely to lose its deodorizing effect due to the fragrance volatilizing during storage, or to have the fragrance smell constantly present while being worn, and that can exert its deodorizing effect in a short time after absorbing bodily fluids.

[0017] Hereinafter, an absorbent article according to one embodiment of the present invention will be described with reference to the drawings.

[0018] In this specification, "wearing an absorbent article" refers to the state in which the absorbent article is worn on the body, regardless of whether the absorbent article is worn before, during, or after absorbing bodily fluids. The "longitudinal direction" refers to the length of the absorbent article, which is the direction along the front and back of the wearer when worn, and is the direction indicated by arrow X in the figure. The inner side of the longitudinal direction refers to the direction toward the center of the longitudinal direction, and the outer side of the longitudinal direction refers to the direction away from the center of the longitudinal direction. The "width direction" refers to the short side direction intersecting (orthogonal to) the longitudinal direction, which is the direction along the left and right of the wearer when worn, and is the direction indicated by arrow Y in the figure. The inner side of the width direction refers to the direction toward the center of the width direction, and the outer side of the width direction refers to the direction away from the center of the width direction. The "thickness direction" refers to the direction in which each component is layered, which is the direction intersecting (orthogonal to) both the longitudinal direction and the width direction, and is the direction indicated by arrow Z in the figure. Furthermore, "skin side" refers to the thickness direction toward the wearer's body when the absorbent article is worn, and "non-skin side" refers to the thickness direction opposite the skin side. Furthermore, body fluids refer to liquids excreted from the body to the outside, such as urine, blood, and water in loose stools.

[0019] (Absorbent articles) Fig. 1 is a plan view of an absorbent article according to one embodiment of the present invention, as seen from the skin side. Fig. 2 is a cross-sectional view taken along the line II-II in Fig. 1. Fig. 3 is an enlarged view of the deodorizing sheet in Fig. 2, where (a) shows an example without edge treatment, (b) shows an example with edge treatment, and (c) shows an example consisting of a single sheet. Fig. 4 is a plan view of the deodorizing sheet. Figs. 2 and 3 show schematic cross sections of the absorbent article. In Figs. 3 and 4, powder fragrance is shown schematically for ease of understanding.

[0020] The absorbent article 10 according to this embodiment can be used as a variety of absorbent articles, not just for adults, but representative examples include light incontinence pads, urine absorption pads, pants-type disposable diapers, tape-fastened disposable diapers, sanitary products, etc.

[0021] 1 and 2, the absorbent article 10 comprises a liquid-permeable top sheet 11 on the skin side, a liquid-impermeable back sheet 12 on the non-skin side, an absorbent body 13 disposed between the top sheet 11 and the back sheet 12, and a deodorizing sheet 14. In addition to these, the absorbent article 10 of this embodiment also comprises left and right three-dimensional gathers 15. The absorbent article 10 may also comprise a carrier sheet that wraps around the absorbent body 13, a transfer sheet that is disposed between the top sheet 11 and the absorbent body 13, etc.

[0022] (Top sheet) The top sheet 11 is a liquid-permeable sheet-like substrate that allows bodily fluids to pass quickly toward the absorbent body 13 and diffuse the bodily fluids in the plane direction of the absorbent body 13. The top sheet 11 is a sheet that is positioned on the skin side when worn and is arranged opposite the back sheet 12 with the absorbent body 13 in between. The top sheet 11 is preferably a substrate that is soft to the touch and does not irritate the skin so that it may come into direct contact with the wearer's skin. Examples of the substrate include hydrophilic sheets, composite nonwoven fabrics that are laminates of the same or different hydrophilic sheets, apertured films such as apertured polyethylene films, and foamed films such as polyethylene foam and urethane foam. Examples of hydrophilic sheets include air-through nonwoven fabrics, thermal-bonded nonwoven fabrics, spunlace nonwoven fabrics, and spunbonded nonwoven fabrics made from one or more of synthetic fibers made from synthetic resins such as polypropylene, polyethylene, and polyester, regenerated fibers such as rayon, and natural fibers such as cotton.

[0023] In order to reduce irritation to the skin, the top sheet 11 may contain lotion, antioxidant, anti-inflammatory component, pH adjuster, antibacterial agent, moisturizer, etc. The shape of the top sheet 11 is not particularly limited, and it may be of any shape as long as it has a size required to guide bodily fluids to the absorbent body 13 without leakage and covers part or all of the absorbent body 13.

[0024] (back seat) The backsheet 12 is a sheet positioned away from the skin when worn. The backsheet 12 may be formed using a liquid-impermeable substrate that prevents body fluids held by the absorbent body 13 from wetting the wearer's clothing. Examples of such substrates include resin films and composite sheets that are laminates of resin films and nonwoven fabrics. The nonwoven fabrics used in the composite sheets may be produced by any method, and examples include single-layer nonwoven fabrics such as spunbonded nonwoven fabrics and meltblown nonwoven fabrics, composite nonwoven fabrics such as spunbonded nonwoven fabric / meltblown nonwoven fabric laminates and spunbonded nonwoven fabric / meltblown nonwoven fabric / spunbonded nonwoven fabric laminates, and composite materials thereof. Examples of resin films include polyester, polyvinyl alcohol, polyethylene, polypropylene, and composite films of polyethylene and polypropylene.

[0025] The back sheet 12 is preferably an air-impermeable resin film (for example, a polyethylene film (PE film)). By making the back sheet 12 air-impermeable, it is possible to reduce the effect on the slip-stop (hot melt) provided on the non-skin side of the back sheet 12 when the powder fragrance 16 of the deodorizing sheet 14 (described later) volatilizes. This makes it possible to prevent a decrease in the adhesive strength of the slip-stop due to the volatilization of the fragrance.

[0026] (absorber) The absorbent body 13 is a member capable of absorbing and retaining mainly bodily fluids, and includes a bodily fluid absorbing material, preferably including absorbent fibers as a base material and a bodily fluid absorbing material retained in the absorbent fibers. The shape of the absorbent body 13 is not particularly limited, and examples thereof include a rectangular, oval, hourglass, etc.

[0027] (absorbent fiber) The absorbent fiber used as the base material of the absorber 13 is not particularly limited as long as it is one generally used in absorbent articles such as sanitary napkins, disposable diapers, and urine absorption pads, and may be formed from materials such as fluff pulp, cotton, rayon, acetate, tissue, absorbent paper, hydrophilic nonwoven fabric, etc. Examples of fluff pulp include wood pulp, synthetic fiber, polymer fiber, non-wood pulp, recycled pulp, etc., which have been defibrated into a cotton-like state.

[0028] (body fluid absorbing material) The body fluid absorbing material of the absorber 13 is not particularly limited as long as it absorbs and retains body fluids, and examples thereof include super absorbent polymers (SAPs). Examples of SAPs include polyacrylates, polyaspartates, (starch-acrylic acid) graft copolymers, (acrylic acid-vinyl alcohol) copolymers, (isobutylene-maleic anhydride) copolymers, and saponified products thereof. Among these, from the viewpoint of absorption per weight, polyacrylates are preferred, alkali metal polyacrylates are more preferred, and sodium polyacrylate is even more preferred. SAPs can be used alone or in combination of two or more.

[0029] SAP is used in the form of particles, fibers, etc., for example, but is preferably used in the form of particles from the viewpoint of ease of handling, etc. In this case, by avoiding the use of SAP in the form of a fine powder that has poor fluidity as a powder and using SAP with a medium particle size, it is possible to improve basic absorption performance and reduce the rough feel that occurs when the absorbent body 13 hardens.

[0030] The absorbent body 13 preferably contains fluff pulp as absorbent fibers and SAP as a body fluid absorbing material. The absorbent fibers and SAP in the absorbent body 13 may be in the form of SAP particles mixed in absorbent fibers, or may be an SAP sheet with SAP particles fixed between absorbent fibers. Another form of absorbent body 13 may be an absorbent sheet containing multiple hydrophilic nonwoven fabrics and SAP fixed between the hydrophilic nonwoven fabrics.

[0031] (Deodorizing sheet) As shown in Figs. 2 to 4, the deodorizing sheet 14 is a thin member with a deodorizing function, and includes a powder fragrance 16. In this embodiment, the deodorizing sheet 14 is disposed between the absorbent body 13 and the back sheet 12. The deodorizing sheet 14 is adjacent to the non-skin side of the absorbent body 13. That is, the absorbent article 10 of this embodiment includes the powder fragrance 16 disposed in close proximity to the absorbent body 13.

[0032] By arranging the deodorizing sheet 14 on the non-skin side of the absorbent 13 containing fluff pulp and SAP, even if the powder fragrance 16 comes into contact with bodily fluids during use and leaks out, the skin-side absorbent 13 can prevent the leaked powder fragrance 16 from coming into contact with the skin. Furthermore, because the deodorizing sheet 14 is arranged on the non-skin side of the absorbent 13, it can absorb odors without reducing absorption performance, unlike when a liquid fragrance is applied to a top sheet 11 or transfer sheet (not shown) that is closer to the skin than the absorbent 13. In this embodiment, the deodorizing sheet 14 is arranged adjacent to the non-skin side of the absorbent 13, but this is not limited to this. For example, the deodorizing sheet 14 may be arranged between the absorbent 13 and the top sheet 11 so as to be adjacent to the skin side of the absorbent 13.

[0033] As shown in Fig. 3, the deodorizing sheet 14 of this embodiment has a powder fragrance 16 and a sheet 17 that sandwiches the powder fragrance 16. That is, the absorbent article 10 of this embodiment includes the sheet 17 that sandwiches the powder fragrance 16. Note that Fig. 3 illustrates three forms of deodorizing sheets 14A to 14C, each having a different shape for the sheet 17.

[0034] (powder fragrance) The powder flavor 16 is a powder flavor, and may be, for example, a flavor base emulsified with an excipient such as dextrin, sugar, or starch, and then spray-dried to form a powder. The powder flavor 16 is preferably an aromatic composition that can mask the urine odor.

[0035] (sheet) The sheet 17 is a member for holding the powder fragrance 16, and sandwiches the powder fragrance 16 inside. In order to prevent the powder fragrance 16 from shifting unevenly in the deodorizing sheet 14 or leaking from the deodorizing sheet 14, the powder fragrance 16 is preferably adhered to the sheet 17 with a hot melt adhesive.

[0036] The sheet 17 of the deodorizing sheet 14A shown in FIG. 3(a) has a first sheet 17a located on the skin side of the powder fragrance 16 and a second sheet 17b located on the non-skin side of the powder fragrance 16. The first sheet 17a and the second sheet 17b are arranged opposite each other in the thickness direction, sandwiching the powder fragrance 16 therebetween. The powder fragrance 16 is adhered to at least one of the first sheet 17a and the second sheet 17b. The first sheet 17a and the second sheet 17b are formed to be approximately the same size. The outer peripheral edges (both longitudinal and widthwise edges) of the first sheet 17a and the second sheet 17b are preferably joined to each other along the entire periphery. Note that FIG. 3(a) shows a schematic cross section of the deodorizing sheet 14A, and therefore the widthwise edges of the first sheet 17a and the second sheet 17b are spaced apart, but are actually joined to each other.

[0037] The deodorizing sheet 14B shown in FIG. 3(b) differs from the deodorizing sheet 14A described above in the edge treatment of the outer peripheral edge, but otherwise has the same configuration as the deodorizing sheet 14A. In the deodorizing sheet 14B, one of the first sheet 17a and the second sheet 17b (the second sheet 17b in FIG. 3(b)) is formed longer on both sides in the width direction than the other sheet (the first sheet 17a in FIG. 3(b)). Then, both widthwise ends of the one sheet are folded back toward the other sheet and bonded to the other sheet, so that both widthwise ends of the deodorizing sheet 14B are covered by the one sheet. Note that the longitudinal ends of the deodorizing sheet 14B may also be folded back in the same way as the widthwise ends, or may be joined to each other without being folded back, as in the deodorizing sheet 14A described above.

[0038] The first sheet 17a on the skin side of the deodorizing sheets 14A and 14B is preferably a water-soluble sheet so that the body fluid can come into contact with the powder fragrance 16 early when the body fluid is absorbed. Examples of water-soluble sheets include PVA (polyvinyl alcohol) film and water-soluble paper, but PVA film is preferred from the viewpoint of barrier properties. By using a water-soluble PVA film for the first sheet 17a, it is possible to suppress the volatilization of the fragrance of the powder fragrance 16 until the body fluid is absorbed, and it is possible to bring the body fluid into contact with the powder fragrance 16 early when the body fluid is absorbed.

[0039] The second sheet 17b on the non-skin side of the deodorizing sheets 14A and 14B is preferably a liquid-impermeable nonwoven fabric. Examples of nonwoven fabric include single-layer nonwoven fabrics such as spunbond nonwoven fabrics and meltblown nonwoven fabrics, composite nonwoven fabrics such as spunbond nonwoven fabric / meltblown nonwoven fabric laminates and spunbond nonwoven fabric / meltblown nonwoven fabric / spunbond nonwoven fabric laminates, and composite materials thereof.

[0040] The sheet 17 of the deodorizing sheet 14C of the embodiment shown in FIG. 3(c) is a single sheet formed in a rolled shape with the longitudinal direction as an axis. The sheet 17 has a skin-side region 17c located on the skin side of the powder fragrance 16 and a non-skin-side region 17d located on the non-skin side of the powder fragrance 16. The skin-side region 17c and the non-skin-side region 17d face each other in the thickness direction, sandwiching the powder fragrance 16 therebetween. The powder fragrance 16 is adhered to at least one of the skin-side region 17c and the non-skin-side region 17d. The widthwise ends of the sheet 17 are overlapped and joined together. Note that both longitudinal ends of the deodorizing sheet 14C may be joined together in the same manner as the deodorizing sheet 14A described above.

[0041] The sheet 17 of the deodorizing sheet 14C is preferably a water-soluble sheet. Examples of water-soluble sheets include PVA (polyvinyl alcohol) film and water-soluble paper, with PVA film being preferred from the viewpoint of barrier properties.

[0042] Furthermore, in order to improve the absorption performance of the absorbent article 10, the sheet 17 of the deodorizing sheet 14 may sandwich SAP in addition to the powdered fragrance 16. For example, the sheet 17 may sandwich a mixture of the powdered fragrance 16 and SAP.

[0043] (weight ratio of powdered flavoring) In this embodiment, the powder fragrance 16 is sandwiched between and adhered to the sheets 17, allowing the powder fragrance 16 to be dispersed in a desired distribution. For example, as shown in Fig. 4, when the deodorizing sheet 14 is divided into three equal parts in the longitudinal direction by imaginary lines VL1 and VL2 extending in the width direction, the amount of powder fragrance 16 dispersed (disposed) in each of the regions 18, 19, and 20 can be adjusted to a desired amount. In this case, the weight ratio (ratio to the total weight (100%) of the powder fragrance 16; the same applies below) of the powder fragrance 16 contained in the region 18 in the longitudinal center of the deodorizing sheet 14 is preferably 50% to 80%, the weight ratio of the powder fragrance 16 contained in the region 19 on one side in the longitudinal direction is preferably 10% to 25%, and the weight ratio of the powder fragrance 16 contained in the region 20 on the other side in the longitudinal direction is preferably 10% to 25%. By setting the distribution of the powdered fragrance 16 within the above range, the deodorizing effect is effectively exerted when absorbing body fluids. In Fig. 4, the powdered fragrance 16 held inside the sheet 17 is shown by a solid line for ease of understanding.

[0044] (3D gathers) As shown in Figures 1 and 2, the left and right three-dimensional gathers 15 are members for preventing leakage of bodily fluids outward in the width direction, and are arranged to extend longitudinally on both widthwise sides of the skin-facing side of the top sheet 11. The left and right three-dimensional gathers 15 have water-repellent and / or waterproof gathered sheets 15a, and are able to stand up from their base ends supported by the top sheet 11 toward their tip (free end) ends. It is preferable to provide elastic stretchable members 15b, such as rubber thread, along the longitudinal direction at the tip ends of the left and right three-dimensional gathers 15. The provision of the elastic stretchable members 15b makes it easier for the three-dimensional gathers 15 to stand up.

[0045] (Gathered sheet) The gathered sheet 15a is a water-repellent and / or waterproof sheet, and is made of, for example, a nonwoven fabric. The nonwoven fabric for the gathered sheet 15a can be any water-repellent and / or waterproof (liquid-impermeable) nonwoven fabric made of hydrophobic fibers, and examples thereof include spunbonded nonwoven fabric, meltblown nonwoven fabric, and composite nonwoven fabric (SMS nonwoven fabric) which is a spunbonded nonwoven fabric / meltblown nonwoven fabric / spunbonded nonwoven fabric laminate.

[0046] (Elastic elastic member) The elastic stretchable member 15b is disposed along the longitudinal direction near the tip of the gathered sheet 15a, imparting standing ability to the tip side and enabling the tip of the gathered sheet 15a and its surrounding area to deform to fit the wearer's body shape. The elastic stretchable member 15b may be made of, for example, natural rubber, synthetic rubber, polyurethane, or the like, in the form of a thread, string, or band.

[0047] The absorbent article 10 configured as described above includes a powder fragrance 16 disposed adjacent to the absorbent body 13. The fragrance of the powder fragrance 16 is less likely to volatilize than a liquid fragrance, so the fragrance is less likely to volatilize during storage, reducing the deodorizing effect, or to constantly smell the fragrance while being worn. Furthermore, because it is a powder fragrance 16, it can also exert a deodorizing effect on urine that has remained on fluff pulp, nonwoven fabric, and other materials other than SAP, unlike deodorizing with SAP, which contains a deodorizing substance. Furthermore, because it is deodorized by the powder fragrance 16, it can exert a deodorizing effect in a short period of time, unlike deodorizing with SAP.

[0048] Thus, according to this embodiment, it is possible to provide an absorbent article 10 with excellent deodorizing performance that is able to exert a deodorizing effect in a short time after absorbing bodily fluids, and is less likely to suffer from a reduction in the deodorizing effect due to the fragrance volatilizing during storage, or to have the fragrance smell constantly present while being worn.

[0049] In this embodiment, the deodorizing sheet 14 is provided and the powder fragrance 16 is held by the sheet 17, but this is not limited to this. For example, the powder fragrance 16 may be contained in the absorbent body 13 without providing the deodorizing sheet 14. Specifically, the powder fragrance 16 may be disposed together with SAP in the absorbent fiber (e.g., fluff pulp) of the absorbent body 13.

[0050] Although the present invention has been described above based on the above embodiment, the present invention is not limited to the content of the above embodiment, and can be modified as appropriate without departing from the scope of the present invention. In other words, all other embodiments, examples, operational techniques, etc. made by those skilled in the art based on this embodiment are naturally included in the scope of the present invention. [Example]

[0051] More preferred examples of this embodiment will be described below with reference to examples and comparative examples, but the present invention is not limited to the following examples in any way.

[0052] (Examples 1 to 4 and Comparative Examples 1 and 2) Absorbent articles of Examples 1 to 4 and Comparative Examples 1 and 2 were produced under the conditions shown in Table 1. Each of these absorbent articles was then evaluated for the following three items ("deodorizing effect," "performance degradation due to storage," and "absorption performance").

[0053] Example 1 The deodorizing sheet, in which the powder fragrance was sandwiched between sheets, was placed adjacent to the lower layer (non-skin side) of the absorbent body. The sheet on the skin side of the sheets sandwiching the powder fragrance was a water-soluble sheet.

[0054] Example 2 The deodorizing sheet, in which the powder fragrance was sandwiched between sheets, was placed adjacent to the upper layer (skin side) of the absorbent body. The sheet on the skin side of the sheets sandwiching the powder fragrance was a water-soluble sheet.

[0055] Example 3 The powdered fragrance was disposed within the absorbent fibers of the absorbent body.

[0056] Example 4 The deodorizing sheet, in which the powder fragrance was sandwiched between sheets, was placed adjacent to the lower layer (non-skin side) of the absorbent body. The sheet on the skin side of the sheets sandwiching the powder fragrance was made of a non-water-soluble nonwoven fabric.

[0057] (Comparative Example 1) The SAP of the absorbent body was SAP containing a deodorizing substance.

[0058] (Comparative Example 2) A transfer sheet sprayed with liquid perfume was placed between the absorbent and the topsheet.

[0059] (Deodorizing effect) The "deodorizing effect" was evaluated by 30 monitors who used the absorbent article and conducted a sensory evaluation of the odor after urination. The evaluation was based on the following criteria. ◎: 21 to 30 people answered that the smell was not bothersome ○: 11 to 20 people answered that the smell was not bothersome △: 6 to 10 people answered that the smell was not bothersome ×: 0 to 5 people answered that the smell was not bothersome

[0060] (Functional deterioration due to storage) For the evaluation of "decrease in functionality due to storage," 30 monitors used absorbent articles that had been left standing in an environment of 50°C and 50% RH for four weeks and performed a sensory evaluation to determine whether the deodorizing function had decreased compared to absorbent articles that had been left standing in an environment of 23°C and 50% RH for the same period. Evaluation was then made according to the following criteria. ◎: 21 to 30 people answered that their function did not decline ○: 11 to 20 people answered that their function did not decline △: 6 to 10 people answered that their function did not decline ×: 0 to 5 people answered that their function did not decline

[0061] (Absorption performance) The "absorption performance" was evaluated by 30 monitors who used the absorbent article and performed a sensory evaluation of the water absorption performance. The evaluation was based on the following criteria. ◎: 21 to 30 people answered that it has good water absorption. ○: 11 to 20 people answered that it has good water absorption. △: 6 to 10 people answered that it has good water absorption. ×: 0 to 5 people answered that it was absorbent

[0062] The results obtained are shown in Table 1.

[0063] [Table 1]

[0064] As shown in Table 1, it was confirmed that Examples 1 to 4 provide absorbent articles with excellent deodorizing performance that are less likely to lose their deodorizing effect due to the fragrance volatilizing during storage, or to have a constant scent of fragrance while being worn, and that can exert their deodorizing effect in a short time after absorbing body fluids.
