[Solution] The above problem is solved by an absorbent article comprising a liquid-permeable top sheet, a liquid-impermeable back sheet, and an absorbent material disposed between the top sheet and the back sheet, wherein a deodorizing and antibacterial material is provided on the skin-facing side of the absorbent material, and the deodorizing and antibacterial material is colored green.

Description

[Technical Field]

[0001] This invention relates to an absorbent article with excellent deodorizing and antibacterial effects, as well as the visual visibility of these effects. [Background technology]

[0002] Traditionally, absorbent products such as urine absorbent pads, panty liners, sanitary napkins, and disposable diapers generally have a structure consisting of a liquid-permeable top sheet, a liquid-impermeable back sheet, and an absorbent core placed between the top sheet and the back sheet. Furthermore, absorbent products are known in which deodorizing and antibacterial materials are added to the inside of the absorbent core for the purpose of deodorizing and antibacterial action of excrement.

[0003] For example, Patent Document 1 discloses an absorbent article that comprises a liquid-permeable surface sheet, a liquid-impermeable back sheet, and an absorbent positioned between the surface sheet and the back sheet, with an auxiliary sheet containing a deodorant between the absorbent and the surface sheet, thereby achieving both the absorption effect of the absorbent and the deodorizing effect of the deodorant. However, with this absorbent article, it is difficult to obtain a deodorizing effect immediately after urination because the auxiliary sheet containing the deodorant is not present in the urination area, and the auxiliary sheet containing the deodorant is not easily visible to the user.

[0004] Patent Document 2 discloses an absorbent article having a liquid-permeable top sheet treated with an antibacterial agent, a liquid-impermeable back sheet, and an absorbent body placed between the top sheet and the back sheet, wherein the absorbent body is composed of an absorbent core and a core wrap sheet treated with a deodorant, resulting in an absorbent article with excellent antibacterial and deodorizing properties. However, in the case of small amounts of excrement, this absorbent article may not be able to reach or come into contact with the deodorant on the core wrap sheet, and the antibacterial and deodorizing effects may not be fully exerted.

[0005] Thus, although there are absorbent articles having a deodorizing and antibacterial effect on excrement inside the absorber, some of the deodorizing and antibacterial members do not exhibit their effects unless they are wetted with water. For example, when the deodorizing and antibacterial member is disposed on the non-skin side of the absorber, there is a risk that the effect will not be exhibited until the excrement reaches that location. Furthermore, when the deodorizing and antibacterial member is disposed inside the absorber, there is a problem that it is difficult for the user to visually recognize at a glance whether the product has a deodorizing and antibacterial effect.

Problems to be Solved by the Invention

[0007] The present invention has been made in view of such circumstances, and an object thereof is to provide an absorbent article in which a deodorizing and antibacterial effect is quickly exhibited and the visibility of the deodorizing and antibacterial effect is good.

Means for Solving the Problems

[0008] The inventor conducted intensive studies and found that, in an absorbent article including a liquid-permeable topsheet, a liquid-impermeable backsheet, and an absorber disposed between the topsheet and the backsheet, by providing a deodorizing and antibacterial member on the skin side surface of the absorber and defining the deodorizing and antibacterial member in a predetermined green color, the above problems can be solved, and the present invention has been completed. That is, the present invention provides the following.

[0009] (1) The first aspect of the present invention is an absorbent article comprising a liquid-permeable topsheet, a liquid-impermeable backsheet, and an absorber disposed between the topsheet and the backsheet, wherein a deodorizing and antibacterial member is provided on the skin side surface of the absorber, and the deodorizing and antibacterial member is colored green.

[0014] According to the present invention, it is possible to provide an absorbent article that exhibits a rapid onset of deodorizing and antibacterial effects, and in which the deodorizing and antibacterial effects are easily visible. [Brief explanation of the drawing]

[0015] [Figure 1] This is a cross-sectional view showing an example of an absorbent article according to the present invention. [Figure 2] This is a plan view showing an example of an opening in the top sheet or second sheet of an absorbent article according to the present invention. [Modes for carrying out the invention]

[0016] (Embodiment) Preferred embodiments of the absorbent article of the present invention (hereinafter referred to as "embodiments") are described in detail below. Throughout the description of the embodiments, the same elements are denoted by the same numbers.

[0017] In this specification, "skin side" means the side of the absorbent article that comes into contact with the wearer's skin when worn, and "non-skin side" means the side of the absorbent article that comes into contact with the wearer's clothing when worn.

[0018] Furthermore, "body fluids" refers to liquids that are expelled from the body, such as urine, blood, and water in loose stools, while "excretion" refers to anything that is excreted from the human body, not limited to liquids, such as urine and loose stools.

[0019] In absorbent materials, the "longitudinal direction" refers to the direction that spans the front and back of the wearer when the absorbent material is worn; the "width direction" refers to the direction that is perpendicular or perpendicular to the "longitudinal direction"; and the "thickness direction" refers to the direction that is perpendicular to both the "longitudinal direction" and the "width direction."

[0020] <Absorbent Articles> One embodiment of the absorbent article 1 according to the present invention will be described with reference to Figure 1. The absorbent article 1 comprises a liquid-permeable top sheet 20, a liquid-impermeable back sheet 30, and an absorbent body 40 positioned between the top sheet 20 and the back sheet 30, arranged in the order of top sheet 20, absorbent body 40, and back sheet 30 from the skin side. Furthermore, a deodorizing and antibacterial member 50 is provided on the skin side of the absorbent body 40.

[0021] The absorbent article 1 of the present invention is not particularly limited, but examples include urine absorbent pads, panty liners, sanitary napkins, disposable diapers, and the like.

[0022] <Top sheet> The base material of the top sheet 20 should have liquid permeability that allows bodily fluids to move from the deodorizing and antibacterial member 50 to the absorbent body 40. For example, it can be formed from materials such as nonwoven fabrics, including thermal bond nonwoven fabrics such as air-through nonwoven fabrics, composite nonwoven fabrics made by laminating thermal bond / spunbond, open films such as open polyethylene films, foamed films such as polyethylene foam and urethane foam, or composite sheets made by laminating these. Among these, air-through nonwoven fabrics and open films with a funnel-shaped cross-section are preferred from the viewpoint of preventing backflow of bodily fluids. Furthermore, in order to reduce skin irritation, it is preferable to include lotion, antioxidants, anti-inflammatory components, pH adjusters, antibacterial agents, moisturizers, etc., in the top sheet 20.

[0023] (Opening in the top sheet) It is preferable to provide openings 21 in the top sheet 20. Providing openings 21 improves liquid permeability and enhances the visibility of adjacent deodorizing and antibacterial members 50. The openings 21 may be mesh-like (Figure 2(a)) or slit-like (Figure 2(b)) to maintain the strength of the top sheet 20, as shown in Figure 2. The openings 21 may be provided uniformly across the entire top sheet 20 or only in a portion of it. The processing method can be carried out without limitation using known methods.

[0024] The area of ​​the opening 21 on the flat surface of the top sheet 20 is preferably 30% or more and less than 60% of the total area of ​​the top sheet 20. If the area of ​​the opening 21 is less than 30%, bodily fluids will not easily spread to the deodorizing and antibacterial component 50 during use, making it difficult for the user to visually perceive the presence of the deodorizing and antibacterial component 50. On the other hand, if it exceeds 60%, the strength of the top sheet 20 will be insufficient, which may lead to the top sheet 20 being damaged during use or affecting operability during production.

[0025] <Second row seats> In the present invention, it is preferable that the absorbent article 1 includes a second sheet (not shown) between the top sheet 20 and the deodorizing / antibacterial member 50. By including the second sheet, cushioning is improved, the fit and wearing comfort of the absorbent article 1 are improved, and bodily fluids that have permeated through the top sheet 20 can be diffused almost uniformly throughout the entire absorbent material.

[0026] The base material of the second sheet only needs to have liquid permeability that allows bodily fluids that have permeated from the top sheet 20 to move to the absorbent material 40 via the deodorizing and antibacterial member 50. For example, it can be formed from materials such as nonwoven fabrics such as thermal bond nonwoven fabrics, which are representative of air-through nonwoven fabrics; composite nonwoven fabrics made by laminating thermal bond / spunbond; open films such as open polyethylene films; foamed films such as polyethylene foam and urethane foam; or composite sheets made by laminating these materials. Among these, air-through nonwoven fabrics and open films with a funnel-shaped cross-section are preferred from the viewpoint of preventing backflow of urine, etc.

[0027] (Opening for the second row seats) When the top sheet 20 does not have an opening 21, it is preferable to provide an opening in the second sheet. The opening in the second sheet may have the same specifications as the opening 21 in the top sheet 20. Furthermore, the area ratio of the opening on the plane of the second sheet is preferably 30% or more and less than 60%, as described above.

[0028] <Back seat> The base material of the backsheet 30 can be any material that is impermeable to liquids so that bodily fluids and excrement held by the absorbent material 40 do not leak into the underwear, and can be formed from materials such as nonwoven fabric, resin film, or composite sheets made by laminating these materials.

[0029] Nonwoven fabrics are not limited by their manufacturing method and include, for example, spunbond and meltblown nonwoven fabrics, or composite nonwoven fabrics made by laminating spunbond / meltblown, spunbond / meltblown / spunbond, and composite materials thereof. Resin films include, for example, polyester, polyvinyl alcohol, polyethylene, polypropylene, and composite films of polyethylene and polypropylene.

[0030] It is preferable that the back sheet 30 be provided with an adhesive portion (not shown) for attaching to underwear or the like.

[0031] <Absorbent> The absorbent material 40 can be formed by mixing pulp fibers as a base material with particles of superabsorbent polymer (SAP). Alternatively, a so-called SAP sheet, which is SAP in sheet form, may be used.

[0032] Pulp fibers are generally not limited as long as they are used in absorbent articles such as sanitary napkins, diapers, and urine absorption pads. For example, they can be formed from materials such as fluff pulp, cotton, rayon, acetate, tissue, absorbent paper, and hydrophilic nonwoven fabrics. Among these, fluff pulp is preferred from the viewpoint of absorbency. Examples of such fluff pulp include wood pulp and non-wood pulp such as synthetic fibers and polymer fibers that have been defibrated into a cotton-like form.

[0033] Superabsorbent polymers (SAPs) are not particularly limited as long as they can absorb bodily fluids and excretions and prevent backflow. For example, they can be formed from materials such as sodium polyacrylate, polyaspartic acid, (starch-acrylic acid) graft copolymer, (acrylic acid-vinyl alcohol) copolymer, (isobutylene-maleic anhydride) copolymer, and their saponified products. Among these, sodium polyacrylate is preferred from the viewpoint of absorption per unit weight.

[0034] <Deodorizing and antibacterial materials> The deodorizing and antibacterial component 50 is provided on the skin-facing side of the absorbent body 40. By being provided on the skin-facing side, bodily fluids that have passed through the top sheet 20 are quickly absorbed by the deodorizing and antibacterial component 50, allowing the deodorizing and antibacterial effect to manifest rapidly.

[0035] Furthermore, the deodorizing and antibacterial component 50 is colored green. By coloring the deodorizing and antibacterial component 50 green, its presence is more easily visible from the skin-facing side of the absorbent article 1, making it easier for the user to recognize that the absorbent article 1 is equipped with a component that has deodorizing and antibacterial effects and that they can enjoy its benefits.

[0036] (Basic weight) The basis weight of the deodorizing and antibacterial material 50 is 7 g / m². 2 More than 40g / m 2 The following is preferable: Basis weight is 7 g / m². 2 If the basis weight is less than 40 g / m², insufficient strength may cause problems with operability. 2 Beyond this point, the wearing comfort deteriorates, and the ability to disperse excrement is also reduced.

[0037] (hue) The deodorizing and antibacterial component 50 is green in color. The green coloring not only improves visibility to the user but also provides a sense of security and cleanliness.

[0038] (L * a * b * value) The green color according to the present invention is CIE1976(L * a * b * ) L obtained in the color system * The value is "90 ≤ L" * <95'', chromaticity a * Value "-5≦a" * <0'', chromaticity b * The value is "0 * It is preferable that the value is ≤10.

[0039] (L * value) L * The value is an indicator of brightness, L * If the value is less than 90, the color will be dull, which may be mistaken for dirt by the user. * If the value is 95 or higher, the image will become overexposed, making it impossible to distinguish it from other components (such as the top sheet 20 or absorber 40).

[0040] (a * value) a * The value is an index of chromaticity, which shows the hue and saturation, a * The red direction, -a * The green line indicates the direction. * If the value is less than -5, the green will be emphasized, and when combined with other components, the color tone may deviate, potentially impairing the aesthetic appeal. * If the value is 0 or greater, it will turn red, which may remind the user of bodily fluids (blood) or dirt.

[0041] (b * value) b * The value is an index of chromaticity, showing hue and saturation, b * Yellow direction, -b * The blue line indicates the direction. * If the value is 0 or less, the color will be in the blue family, which is different from green and therefore unsuitable. * If the value exceeds 10, the color will turn yellowish, which may remind the user of excrement.

[0042] CIE1976(L * a​* b * ) L in the color system * value, a * value, b * The value can be measured using a color difference system. For example, using the "Spectroscopic Whiteness Meter / Color Difference Meter PF7000" manufactured by Nippon Denshoku Industries Co., Ltd., the value can be determined by measuring the reflected light when 10 sheets are stacked, under measurement conditions of light source C and a viewing angle of 2°.

[0043] (hue angle) The green color according to the present invention is L * a * b * Chromaticity a in the color space chromaticity diagram * and chromaticity b * In the plane showing the red (+a * It is preferable that the hue angle θ, obtained by rotating the axis counterclockwise with respect to the axis, is in the range of 90° < θ < 270°, and more preferably 90° < θ < 210°. Note that chromaticity a * If the value is 0, it is not included.

[0044] (Cellulose fiber containing metal ions) The deodorizing and antibacterial material 50 preferably contains metal ion-containing cellulose fibers. The metal ion-containing cellulose preferably contains ions of one or more metal elements selected from the group Ag, Au, Pt, Pd, Ni, Mn, Fe, Ti, Al, Zn, and Cu in addition to oxidized cellulose fibers having carboxyl groups or carboxylate groups on their surface. The inclusion of metal ions imparts deodorizing and antibacterial functions.

[0045] The content ratio of metal ion-containing cellulose fibers in the deodorizing and antibacterial material 50 is preferably 5 wt% to 15 wt%. If the content ratio is less than 5 wt%, the amount of metal particles in the deodorizing and antibacterial material 50 is insufficient, resulting in poor deodorizing and antibacterial effects. If the content ratio exceeds 15 wt%, the dewatering load during papermaking may increase.

[0046] (Oxidized cellulose fiber) Oxidized cellulose fibers, which serve as the base material for metal ion-containing cellulose fibers, can be produced by oxidizing cellulose fibers such as wood pulp using an N-oxyl compound as a catalyst. This oxidation reaction selectively oxidizes the primary hydroxyl group at the C6 position of the glucopyranose ring on the cellulose surface, yielding oxidized cellulose fibers having carboxyl groups or carboxylate groups on the surface. Natural cellulose is preferred as the raw material.

[0047] A carboxyl group is a group represented by -COOH, while a carboxylate group is represented by -COO - This refers to the group represented by [the symbol]. The counterion of the carboxylate group when manufacturing oxidized cellulose fibers is not particularly limited. Then, a metal ion, as described later, replaces the above counterion and forms an ionic bond with the carboxylate group. Furthermore, the carboxyl group is thought to coordinate with metal ions such as copper ions. The carboxyl group or carboxylate group together is also called an "acid group".

[0048] (Adjustment of acid groups) The amount of acid groups in the cellulose fibers is preferably between 0.2 mmol / g and 2.2 mmol / g. If the amount of acid groups is less than 0.2 mmol / g, the amount of metal ions present on the surface of the cellulose fibers is insufficient, resulting in poor deodorizing effect. If the amount of acid groups exceeds 2.2 mmol / g, the water-filtration properties of the deodorizing and antibacterial material 50 during papermaking deteriorate, and the dewatering load increases.

[0049] The acid group content can be measured by the method disclosed in paragraph 0021 of Japanese Patent Publication No. 2008-001728. Specifically, 60 mL of a slurry containing 0.5% to 1.0% by mass is prepared using a precisely weighed dried cellulose sample, and the pH is adjusted to approximately 2.5 with a 0.1 mol / L hydrochloric acid aqueous solution. Then, a 0.05 mol / L sodium hydroxide aqueous solution is added dropwise, and the electrical conductivity is measured. The measurement is continued until the pH reaches approximately 11. The amount of sodium hydroxide (V) consumed until the electrical conductivity changes gradually, indicating a weak acid neutralization stage, is used to determine the amount of acid groups X1 using the following formula. X1 (mmol / g) = V (mL) × 0.05 / Mass of cellulose (g)

[0050] (Bonding of metal ions) Next, an aqueous solution containing a metal compound is brought into contact with the oxidized cellulose fibers, and metal ions derived from the metal compound form ionic bonds with the carboxylate groups. It is thought that the carboxyl groups either ionize and form ionic bonds with the metal ions via the carboxylate groups, or coordinate with the metal ions as described above. The aqueous solution of the metal compound is an aqueous solution of a metal salt. Examples of metal salts include complexes (complex ions), halides, nitrates, sulfates, and acetates. The metal salt is preferably water-soluble.

[0051] Regarding the method of contact with the metal compound, a pre-prepared dispersion of cellulose fibers may be mixed with an aqueous solution of the metal compound, or the dispersion containing cellulose fibers may be applied to a substrate to form a film, and the aqueous solution of the metal compound may be added to the film to impregnate it. In this case, the film may remain fixed on the substrate or may be peeled off from the substrate.

[0052] (Metal ion content) The metal ion content in oxidized cellulose fibers is preferably between 10 mg / g and 60 mg / g. If the metal ion content is less than 10 mg / g, the deodorizing and antibacterial effects are inferior. If the metal ion content exceeds 60 mg / g, costs will increase and there is a risk of causing metal allergies.

[0053] The metal ion content can be measured by the following method. (1) Oxidized cellulose fibers were completely dried at 60°C. (2) 0.04 g of this dried sample was taken and 10 mL of concentrated nitric acid was added. (3) This extract was diluted 10-fold and measured using inductively coupled plasma emission spectroscopy with a Shimadzu Corporation multi-type ICP emission spectrometer (ICPE-9000).

[0054] (Manufacturing method for deodorizing and antibacterial materials) The deodorizing and antibacterial component 50 is produced by papermaking using papermaking raw materials containing cellulose fibers. Other papermaking raw materials besides cellulose fibers include, for example, virgin pulp such as softwood pulp (NBKP) or hardwood pulp (LBKP), or recycled paper pulp. These pulps are blended appropriately in predetermined types and proportions according to the required quality of the sanitary paper. Various chemicals may be added (internally) to the papermaking raw materials to ensure required quality and operational stability. These chemicals include softeners, bulking agents, dyes, dispersants, wet strength enhancers, dry strength enhancers, water filtration enhancers, pitch control agents, and yield enhancers. The deodorizing and antibacterial component 50 can be manufactured using known papermaking methods.

[0055] Although the present invention has been described above using embodiments, it goes without saying that the technical scope of the present invention is not limited to the scope described in the above embodiments. It will be obvious to those skilled in the art that various modifications or improvements can be made to the above embodiments. Furthermore, it is clear from the claims that such modified or improved forms may also be included in the technical scope of the present invention. [Examples]

[0056] The present invention will be described in detail below with reference to examples. However, the present invention is not limited in any way to the examples shown below.

[0057] (Sample preparation) Absorbent articles were manufactured according to Examples 1-3 and Comparative Examples 1-8 shown in Table 1. Top sheet: All examples and comparative examples used the same material and dimensions, with only the area ratio of the openings being varied. The shape of the openings was always mesh-like. Absorbent material: The same material and dimensions were used in all examples and comparative examples. Deodorizing and antibacterial materials: All examples and comparative examples used materials of the same size and dimensions, with only the hue being varied.

[0058] In Examples 1-3 and Comparative Examples 1-7, an absorbent material was laminated onto a backsheet, then a deodorizing and antibacterial component was laminated, followed by a top sheet, and then joined together with a hot-melt adhesive to obtain an absorbent article. On the other hand, in Comparative Example 8, a deodorizing and antibacterial component was laminated onto a backsheet, then an absorbent material was laminated, followed by a top sheet, and then joined together with a hot-melt adhesive to obtain an absorbent article. The obtained absorbent articles were evaluated as follows. The results are shown in Table 1.

[0059] 1. Speed ​​of deodorizing and antibacterial effect onset The speed of deodorizing and antibacterial effect development was evaluated using the following method: An absorbent material containing 150 mL of 0.9% physiological saline solution was poured into the top sheet and placed in a gas bag. 0.5 L of 5 ppm hydrogen sulfide gas was injected, and the deodorizing ability after 90 seconds was evaluated by 20 panelists. For comparison, a blank test was conducted without placing the absorbent material in the gas bag. ○: 0-7 people felt there was an odor. △: 8-13 people felt there was an odor. ×: More than 14 people felt there was an odor.

[0060] 2. Visibility of deodorizing and antibacterial materials Regarding the visibility of deodorizing and antibacterial materials, 20 panelists visually inspected the absorbent surface of absorbent materials from a distance of 30 cm and scored them according to the following criteria. The total points from the 20 panelists were then used to make a judgment according to the following criteria. (Scoring criteria) 2 points: Deodorizing and antibacterial materials can be clearly seen. 1 point: Although it is difficult to distinguish whether it is a deodorizing or antibacterial material, it is visible. 0 points: Deodorizing and antibacterial materials are not visible. (Judgment criteria) ○: Total points are 30 or more △: Total points are between 10 and 30. ×: Total points are less than 10

[0061] 3. Aesthetic properties of absorbent articles Regarding the aesthetic appeal of absorbent materials, 20 panelists visually inspected the absorbent surface of each material from a distance of 30 cm and scored them according to the following criteria. The total points from the 20 panelists were then used to make a final judgment according to the following criteria. (Scoring criteria) 2 points: The overall harmony is good, and I would like to use it. 1 point: It feels a bit strange, but it's usable. 0 points: I find it unpleasant and don't want to use it. (Judgment criteria) ○: Total points are 30 or more △: Total points are between 10 and 30. ×: Total points are less than 10

[0062] [Table 1]

[0063] As a result, as shown in Table 1, the absorbent articles of Examples 1 to 3 were good in terms of speed of effect onset, visibility, and aesthetic appeal. On the other hand, the absorbent articles of Comparative Examples 1 to 7 were inferior in either visibility or aesthetic appeal. Furthermore, Comparative Example 8, in which the placement of the deodorizing and antibacterial components was changed, was inferior not only in visibility and aesthetic appeal but also in the speed of effect onset.

[0064] From the above, it has been confirmed that the absorbent article of the present invention can provide an absorbent article in which deodorizing and antibacterial effects appear quickly and the effects are easily visible. [Explanation of symbols]
