The fiber mass is configured to be visible from the outside,
The absorbent article in which the light transmittance of the fiber lump portion of the nonwoven fabric is lower than the light transmittance of a portion of the nonwoven fabric where the fiber lump does not exist.

  Since the light transmittance of the part of the fiber lump made of organic cotton fibers is lower than the light transmittance of the surrounding part, the user can easily visually recognize the fiber lump from the outside. Thereby, the user can actually feel that the organic cotton fiber is used, and can obtain a sense of security with respect to the product.

  According to a preferred aspect, the plurality of fiber masses are provided biased toward the surface side of the absorbent article in the thickness direction of the absorbent article. Since the fiber lump is biased toward the surface of the absorbent article, the user can more easily visually recognize the fiber lump from the outside.

  According to a preferred aspect, the absorbent article has a colored sheet overlapping the nonwoven fabric, and the colored sheet is provided inside the nonwoven fabric in the thickness direction of the absorbent article. Since the colored sheet is provided inside the nonwoven fabric, the white fiber mass can be made more conspicuous from the outside. Thereby, the user can visually recognize the fiber lump more easily from the outside.

According to a preferred embodiment, the fiber mass has a fiber density of 0.075 to 0.2 g / cm ³ . The fiber lump can be made more conspicuous by increasing the fiber density of the fiber lump. Thereby, the user can visually recognize the fiber lump more easily from the outside.

  According to a preferred aspect, the nonwoven fabric further includes a synthetic fiber, and a region having a density smaller than the density of the fiber mass and the synthetic fiber is formed around the fiber mass. Since there is a low density area around the fiber mass, the fiber mass can be made more conspicuous. Thereby, the user can visually recognize the fiber lump more easily from the outside.

  According to a preferred aspect, the nonwoven fabric includes synthetic fibers, and the organic cotton fibers have an average fiber length that is shorter than an average fiber length of the synthetic fibers. By making the average fiber length of the synthetic fiber 12 longer, the strength of the nonwoven fabric and the absorbent article as a whole can be improved, and fiber flaking during production and use can be suppressed. On the other hand, by shortening the average fiber length of the organic cotton fiber 10, the heat fusion point between the synthetic fibers 12 can be reduced, and appropriate flexibility as a nonwoven fabric and an absorbent article can be realized.

  According to a preferred embodiment, the organic cotton fiber is not thermally fused to the synthetic fiber. Since the fiber lump made of the organic cotton fiber is not thermally fused to the synthetic fiber, the boundary between the fiber lump and the synthetic fiber becomes more conspicuous. Thereby, the user can visually recognize the fiber lump more easily from the outside.

  According to a preferred aspect, there is provided an absorbent article package comprising the absorbent article of the above aspect and a packaging bag for packaging the absorbent article, wherein the organic cotton fibers are used in the packaging bag. A mark that allows the user to recognize it is attached.

Thereby, the user can be given a sense of security that is gentle to the skin.

  According to one aspect, the absorbent article is provided with a mark that allows a user to recognize the use of the organic cotton fiber.

  Even when the absorbent article is taken out of the packaging bag, the absorbent article is marked so that the user is aware of the use of organic cotton fiber, so that the user is clearly using organic cotton fiber. Can let you know. Thereby, the user can be given a sense of security that is gentle to the skin.

  Hereinafter, with reference to drawings, the detail of the absorptive article concerning one embodiment is explained. The absorbent article of the present invention is, for example, a disposable diaper or a sanitary napkin. In the following embodiments, a disposable diaper will be described as an example and described in detail.

  In the following description of the drawings, the same or similar parts are denoted by the same or similar reference numerals. However, it should be noted that the drawings are schematic and ratios of dimensions and the like may differ from actual ones. Therefore, specific dimensions and the like should be determined in consideration of the following description. Moreover, the part from which the relationship and ratio of a mutual dimension differ also in between drawings may be contained.

  FIG. 1 is a plan view of an absorbent article 1 according to an embodiment. FIG. 2 is a plan view of the absorbent article 1 viewed from the side opposite to FIG. The absorbent article 1 has a longitudinal direction L and a width direction W. The longitudinal direction L is a direction extending from the front side (abdomen side) of the wearer to the rear side (back side), or a direction extending from the rear side of the wearer to the front side. The width direction W is a direction orthogonal to the longitudinal direction L. Hereinafter, the side facing the wearer's skin during use may be referred to as the “skin side”. In addition, a side that is directed away from the wearer's skin during use may be referred to as a “non-skin side”.

  The absorbent article 1 includes a top sheet 3, a back sheet 4, and an absorbent body 7. The absorber 7 is provided between the top sheet 3 and the back sheet 4. The top sheet 3 may be composed of a liquid permeable sheet.

  A liquid-impermeable leak-proof sheet 5 may be provided between the back sheet 4 and the absorbent body 7. The leak-proof sheet 5 covers at least the absorber 7. The back sheet 4 covers the leakproof sheet 5 and extends to the outside of the leakproof sheet 5. The area | region which does not overlap with the leak-proof sheet | seat 5 among the back surface sheets 4 is extended from the front side edge part of the longitudinal direction L to the rear side edge part on both the outer sides in the width direction W.

  The top sheet 3 and the back sheet 4 are made of nonwoven fabric. FIG. 3 is a schematic diagram showing a cross section of the top sheet 3 or the back sheet 4. This nonwoven fabric includes organic cotton fibers 10 and synthetic fibers 12. Here, “organic cotton” means cotton that has been certified and certified as organic in the agricultural stage based on international standards (standards of countries according to CODEX).

  The synthetic fiber 12 may be a fiber made of a thermoplastic resin. Examples of the fiber made of a thermoplastic resin include an olefin resin, a polyester resin, a polyamide resin, and any combination thereof. The fiber made of a thermoplastic resin may be hydrophilized with a hydrophilizing agent.

  The fineness of the synthetic fiber 12 is not particularly limited, but is 1.1 to 8.8 dtex, preferably 1.5 to 4.6 dtex in terms of the strength, flexibility, touch, liquid permeability, and the like of the nonwoven fabric. It is preferable.

  Further, a synthetic fiber containing 10 to 40%, more preferably 20 to 30% of a fiber having a fineness of less than 2.0 dtex may be used as the fiber having a fineness of 2.0 dtex or more. In this case, it is possible to include a synthetic fiber having a short fiber length while keeping the average fiber length long. When the synthetic fiber 12 includes fibers with a fine count, it is possible to further suppress the fiber lump of the cotton fibers from dropping from the nonwoven fabric.

  The organic cotton fiber 10 forms a plurality of fiber masses 11 within the nonwoven fabric. The organic cotton fiber 10 may have an average fiber length shorter than that of the synthetic fiber 12. Thereby, the organic cotton fiber 10 becomes easy to form the fiber lump 11 in the nonwoven fabric.

  A fiber mass 11 made of organic cotton fibers 10 is configured to be visible from the outside. The light transmittance of the portion of the fiber mass 11 in the nonwoven fabric is lower than the light transmittance of the portion of the nonwoven fabric where the fiber mass 11 does not exist. In the present specification, the light transmittance means the visible light transmittance.

  Since the light transmittance of the portion of the fiber mass 11 made of the organic cotton fiber 10 is lower than the light transmittance of the surrounding portion, the user can easily visually recognize the fiber mass 11 from the outside. Thereby, the user can actually feel that the organic cotton fiber 10 is used, and can obtain a sense of security with respect to the product.

  In addition, by shining light on the nonwoven fabric and checking it with the naked eye, the portion of the fiber lump 11 made of the organic cotton fiber 10 appears whiter than the surrounding area, so that the light transmittance of the fiber lump 11 portion and its surroundings The difference from the light transmittance of the part can be confirmed.

  As shown in FIG. 3, the plurality of fiber masses 11 are preferably provided so as to be biased toward the surface side of the absorbent article 1 in the thickness direction of the absorbent article 1. Here, in the thickness direction, the absorbent article 1 is equally divided into two layers on the surface side and a central layer, and 60% or more, preferably 70% or more of the plurality of fiber masses 11 are on the surface side. When present in the (external side) layer, it is assumed that the plurality of fiber masses 11 are provided biased toward the surface side of the absorbent article 1. In addition, the fiber lump existing in the surface side (external side) layer means that a part of the fiber lump exists in the surface side (external side) layer.

  Since the plurality of fiber masses 11 are provided so as to be biased toward the surface side of the absorbent article 1, the user can more easily visually recognize the fiber masses from the outside. In addition, it is preferable that the fiber lump 11 is not exposed to the surface of a nonwoven fabric from a viewpoint which prevents the fiber lump 11 falling off from a nonwoven fabric.

  X-ray CT can be used to confirm the deviation of the fiber mass 11 in the thickness direction. Specifically, X-ray CT (for example, FLEX-M863 manufactured by Beamsense Co., Ltd.) is performed so that the other surface is photographed from one surface of the non-woven fabric including the portion of the fiber mass 11 to be measured. Take a picture. The bias of the fiber mass 11 can be determined by confirming the 10 fiber masses 11 in the same nonwoven fabric using the image obtained by photographing. In addition, it can be confirmed whether the fiber lump 11 in the sample after imaging | photography is the fiber lump 11 of an organic cotton fiber by utilizing the dyeing | staining method by Kayastein Q mentioned later.

In general, the nonwoven fabric preferably has a basis weight in the range of 10 to 60 g / cm ² . The thickness of the nonwoven fabric is preferably 0.5 to 5.0 mm, more preferably 0.8 to 3.5 mm. The thickness of the nonwoven fabric can be measured using a thickness meter (Peacock dial thickness gauge manufactured by Ozaki Mfg. Co., Ltd.) having a measurement terminal with a measurement pressure of 3 g / cm ² and a diameter of 10 mm. Specifically, 10 different thicknesses of the target nonwoven fabric are measured, and the “thickness” is obtained from the average value.

  In the nonwoven fabric having the above thickness, the weight ratio of the organic cotton fiber to the synthetic fiber is preferably less than 25%. Under this condition, by providing the fiber mass 11 in the center of the nonwoven fabric in the thickness direction, it is possible to further prevent the organic cotton fibers from falling off during the manufacturing process and during product use.

  The weight ratio of the organic cotton fiber to the synthetic fiber can be calculated by the following method. First, a test piece having a unit area (for example, 5 cm × 5 cm) is taken out from the nonwoven fabric. The organic cotton fiber is taken out from the test piece, and the weight of the taken out organic cotton fiber is measured. Thereby, the weight ratio of the organic cotton fiber to the synthetic fiber can be calculated.

  Moreover, when taking out organic cotton fiber from a test piece, it is necessary to distinguish the difference between synthetic fiber and organic cotton fiber. Whether the fibers in the nonwoven fabric are organic cotton fibers or synthetic fibers can be confirmed by the following method. First, Kayastein Q (manufactured by Nippon Kayaku Co., Ltd.) in the same amount as the test piece is weighed and dissolved in ion-exchanged water (60 to 70 degrees) 100 times the weight of Kayastein Q. This solution is heated, and immediately before the solution boils, a test piece washed with a neutral detergent is put into the solution. Then, after boiling the solution for 5 minutes, the test piece was quickly washed with water and dried. At this point, the fiber mass is dyed in a color corresponding to the type of fiber. Thereafter, the fiber mass can be identified based on the hues of Kayastein Q to various fibers.

  The organic cotton fiber 10 contained in the nonwoven fabric preferably has an average fiber length shorter than the average fiber length of the synthetic fiber 12 and / or has a fineness finer than the fineness of the synthetic fiber 12. By increasing the average fiber length of the synthetic fiber 12 and / or increasing the fineness of the synthetic fiber 12, it is possible to improve the strength of the entire nonwoven fabric and to suppress fiber flaking during production and use. Can do. On the other hand, by shortening the average fiber length of the organic cotton fiber 10 and / or reducing the fineness of the organic cotton fiber 10, the heat-bonding point between the synthetic fibers 12 is reduced, and appropriate flexibility as a nonwoven fabric is realized. it can.

  “Average fiber length” is defined as the individual fiber on the glass plate with the scale “A7.1.1 A method (standard method)” in “A7.1 Measurement of fiber length” in Annex A of JIS L 1015: 2010. The average fiber length is measured according to “Method for Measuring Length of”. The above method corresponds to a test method corresponding to ISO 6989 issued in 1981.

  In FIG. 3, the cross section of the single layer nonwoven fabric which comprises the surface sheet 3 or the back surface sheet 4 is shown. Instead, the top sheet 3 or the back sheet 4 may have a multilayer structure in which a plurality of nonwoven fabrics are superimposed.

  FIG. 4 shows a cross section of a part of the absorbent article (for example, line F3-F3 in FIG. 1). It is preferable that the absorbent article 1 has the coloring sheet 300 which overlaps with the nonwoven fabric which comprises the surface sheet 3 and / or the back surface sheet 4. FIG. The colored sheet 300 is provided inside the nonwoven fabric constituting the top sheet 3 and / or the back sheet 4 in the thickness direction of the absorbent article 1. Since the colored sheet 300 is provided inside the nonwoven fabric containing the organic cotton fiber 10, the white fiber mass 11 can be made more conspicuous. Thereby, the user can visually recognize the fiber lump 11 from the outside more easily.

The fiber density of the fiber mass 11 made of the organic cotton fiber 10 is preferably 0.075 to 0.2 g / cm ³ . By increasing the fiber density of the fiber mass 11, the fiber mass 11 can be made more conspicuous. Thereby, the user can visually recognize the fiber lump 11 from the outside more easily.

Further, from the viewpoint of making the fiber mass 11 stand out, the fiber density of the fiber mass 11 is preferably 0.02 g / cm ³ or more larger than the fiber density of the synthetic fiber 12.

  As shown in FIGS. 3 and 4, it is preferable that a region 15 having a density smaller than the density of the fiber mass 11 and the synthetic fiber 12 is formed around the fiber mass 11. Since the low density area 15 exists around the fiber mass 11, the fiber mass 11 can be made more conspicuous. Thereby, the user can visually recognize the fiber lump 11 from the outside more easily.

  Preferably, the organic cotton fiber 10 is not thermally fused to the synthetic fiber 12. Since the fiber lump 11 made of the organic cotton fiber 10 is not thermally fused to the synthetic fiber 12, the boundary between the fiber lump 11 and the synthetic fiber 12 becomes more conspicuous. Thereby, the user can visually recognize the fiber lump 11 from the outside more easily.

  In addition, it can be performed by the method using said Kaya stain Q whether the fiber lump 11 in a nonwoven fabric consists of organic cotton fiber or a synthetic fiber.

  FIG. 5 is a view showing a package for absorbent articles according to an embodiment. The package includes an absorbent article 1 including a non-woven fabric and a packaging bag 100 for packaging the absorbent article 1. The structure of the absorbent article 1 is as described above.

  The packaging bag 100 accommodates a plurality of absorbent articles 1. A mark 82 is attached to the packaging bag 100 to allow the user to recognize the use of the organic cotton fiber 10. Furthermore, it is preferable that the absorbent article 1 is also provided with a mark 84 that allows the user to recognize the use of the organic cotton fiber 10. The mark 84 attached to the absorbent article 1 is a mark that gives the user the same recognition as the mark 82 attached to the packaging bag 100. Specifically, the mark 84 attached to the absorbent article 1 may be the same as or similar to the mark 82 attached to the packaging bag 100. If the user can recognize the use of the organic cotton fiber 10, the mark 84 attached to the absorbent article 1 may be different from the mark 82 attached to the packaging bag 100.

  The marks 82 and 84 may be marks certified by an external organization that proves the use of organic cotton. In this case, the reliability that the organic cotton is used can be improved, and a higher sense of security can be given to the user.

  2 and 5, the same marks 82 and 84 are attached to both the absorbent article 1 and the packaging bag 100. Instead of this, the mark 82 attached to the absorbent article 1 is not exactly the same as the mark 84 attached to the packaging bag 80, but may be similar. Even in this case, the use of the organic cotton fiber can be recognized by the user.

  Thereby, in the state where the absorbent article 1 is wrapped in the packaging bag 100, the user can recognize the use of the organic cotton fiber by the mark 82 attached to the packaging bag 100. Further, even when the absorbent article 1 is taken out from the packaging bag 100, the user can be explicitly notified that the organic cotton fiber is used by the mark 84 attached to the absorbent article 1. Therefore, it is possible to give the user a sense of security that it is gentle to the skin.

  The plurality of absorbent articles 1 may be individually packaged in the packaging bag 100. In this case, the mark which makes a user recognize use of organic cotton fiber may be attached to the packaging material which wraps the absorbent article 1 individually.

  Although the present invention has been described in detail using the above-described embodiments, it is obvious to those skilled in the art that the present invention is not limited to the embodiments described in this specification. The present invention can be implemented as modified and changed modes without departing from the spirit and scope of the present invention defined by the description of the scope of claims. Therefore, the description of the present specification is for illustrative purposes and does not have any limiting meaning to the present invention.
