Definitions
- the present invention relates to an absorbent article that absorbs bodily fluids such as urine, sweat, blood, and lymph that are mainly discharged from the human body.
- incontinence pads for light incontinence (hereinafter simply referred to as “incontinence pads”) are commercially available. Since such an incontinence pad only needs to cope with a small amount of urine leakage, it is small and thin, and does not resonate with the outer when worn. For this reason, the demand is increasing in recent years.
- Patent Document 1 an absorbent article that can be poured into a toilet after use is examined.
- Patent Document 1 has a liquid-permeable surface sheet positioned on the skin surface side when worn and a water-decomposable back sheet positioned on the non-skin surface side, and the surface surface of the surface sheet is hydrophobic.

- the absorbent article disclosed in Patent Document 1 described above contains hydrophobic fibers in the top sheet, and even if it absorbs liquid at the time of wearing, it does not disintegrate immediately, but it is exposed to a large amount of water. Since it takes a long time for water to dissolve, there is a risk that the toilet piping will become clogged if it is poured into a flush toilet.
- An object of the present invention is to provide an absorbent article that absorbs a small amount of liquid, does not collapse by the absorbed liquid, and does not clog the toilet piping even if it flows into a flush toilet.
- the absorbent article which concerns on 1 aspect of this invention is equipped with the pulp layer containing the fiber which uses the fiber which uses a pulverized pulp or a pulverized pulp as a main raw material,
- the said pulp layer was formed by apply
- the structure which has a water-repellent surface layer part is taken.
- an absorbent article that absorbs a small amount of liquid, does not collapse by the absorbed liquid, and does not clog the toilet piping even if it flows into a flush toilet.
- the conceptual diagram which shows the structure of the absorbent article which concerns on Embodiment 1 of this invention Schematic showing how the absorbent article is mounted on trunks-type underwear
- 4 (a) to 4 (h) are diagrams showing embossed patterns.
- FIG. 1 is a conceptual diagram showing a configuration of an absorbent article 10 according to Embodiment 1 of the present invention.
- the absorbent article 10 will be described with reference to FIG. FIG. 1 shows a cross section of the absorbent article 10.
- the absorbent article 10 will be described assuming a male incontinence pad as an example.
- the absorbent article 10 has a surface sheet layer 11, a first pulp layer 12, a second pulp layer 13, a third pulp layer 15, a fourth pulp layer 17, a fifth pulp layer 19 and a first layer laminated in order from the skin surface side. It has 6 pulp layers 21.
- the top sheet layer 11 is a paper having a skin surface and water decomposability when the absorbent article 10 is worn on the human body.
- water disintegration is a property in which entangled fibers are rapidly separated by a water flow having a predetermined flow velocity, and each separated element has a size equal to or smaller than the cross-sectional area of the drain pipe and is dispersed in water.
- the minimum drain pipe inner diameter of a general house is 5.0 cm
- each separated element may be at least approximately 19.6 cm 2 in size.
- the amount of water necessary for the hydrolysis is preferably three times or more the volume of the object to be hydrolyzed.
- the surface sheet layer 11 has liquid permeability and is formed from a material containing pulp paper or pulp as a main material, that is, a material containing a cellulose-based component.
- a material containing pulp paper or pulp as a main material that is, a material containing a cellulose-based component.
- the pulp content is 30% or more. Further, it is more desirable that the pulp content is 50% or more. Furthermore, it is even more desirable that the pulp content is 80% or more.
- the flexibility as the absorbent article 10 can be improved, or the production efficiency at the time of production can be improved.
- the pulp in the case where the surface sheet layer 11 is formed from a material mainly composed of pulp various raw pulps can be used.
- the raw material pulp include wood pulp, synthetic pulp, waste paper pulp, and toilet paper material.
- Wood pulp is obtained from, for example, softwood bleached kraft pulp obtained from conifers such as red pine, Ezo pine, todo pine, Douglas fir, hemlock, and spruce, and from broadleaf trees such as beech, oak, hippopotamus, eucalyptus, oak, poplar, and alder. Pulp formed by blending hardwood bleached kraft pulp obtained at a predetermined ratio can also be used. However, from the viewpoint of production, it is desirable to use raw pulp made of softwood bleached kraft pulp.
- natural fibers as the material of the surface sheet layer 11.
- natural fibers include kenaf, bamboo fiber, cocoon, cotton, silk thread, and sugar cane.
- the material used for the surface sheet layer 11 is not limited to the above.
- the surface sheet layer 11 As a method for producing the surface sheet layer 11, there is a wet paper making method in which a sheet is formed by dispersing several millimeters of fiber in water and making the dispersed fiber with a wire mesh. Moreover, the surface sheet layer 11 may be manufactured by a spunlace method.
- the spunlace method is also called the hydroentanglement method. It is made by guarding short fibers and arranging the fibers to make a web. The jet stream is jetted onto the web, and the fibers are entangled with each other by water pressure to form a sheet. Is the method.
- the surface sheet layer 11 is subjected to a water repellent treatment by applying a water repellent to the surface on the skin side when the absorbent article 10 is worn on the human body.
- the surface of the top sheet layer 11 on which the water repellent is applied is referred to as a water repellent surface.
- the water repellent and the application method will be described later.
- the first pulp layer 12 is laminated between the top sheet layer 11 and the second pulp layer 13.
- the 1st pulp layer 12 is comprised by the countless fiber which uses a ground pulp or a ground pulp as a main raw material.
- the first pulp layer 12 may be configured so that the degree of denseness of fibers in the thickness direction is different.
- the first pulp layer 12 is formed, for example, by an airlaid method in which pulverized pulp or innumerable fibers mainly composed of pulverized pulp are stacked along an air flow flowing downward.
- the 1st pulp layer 12 formed in this way is pressed by the press member, and the bulkiness is adjusted.
- FIG. 1 is a schematic view, the first pulp layer 12 seems to have a considerable thickness, but in practice it is configured to be thin.
- the pulverized pulp refers to a pulverized raw material pulp, which is a raw material such as paper material, which is finely pulverized with a pulverizer or the like.
- a pulverized raw material pulp which is a raw material such as paper material, which is finely pulverized with a pulverizer or the like.
- Various raw pulps can be used as the material for the pulverized pulp, which is the same as the raw pulp constituting the top sheet layer 11.
- the pulverized pulp is formed by pulverizing the pulp material into a cotton shape, when the cotton-shaped pulverized pulp is piled, it becomes easier to form a space between the fibers. Since this space is formed innumerably between the fibers, the bulk of the first pulp layer 12 is increased by a smaller basis weight than the surface sheet layer 11 by the amount of this space. be able to.
- the first pulp layer 12 from the cotton-like pulverized pulp as described above, a space between the fibers can be formed to increase the degree of freedom of movement of each fiber, and the first pulp The bulkiness of the layer 12 can be further increased. Thereby, it can contribute to the improvement of the softness
- the second pulp layer 13 to the sixth pulp layer 21 are subjected to a water repellent treatment by applying a water repellent to the surface layer portion on the non-skin surface side when the absorbent article 10 is worn on the human body.
- the surface layer portions to which the water repellent agent of the second pulp layer 13 to the sixth pulp layer 21 is applied are referred to as water repellent surface layer portions 14, 16, 18, 20, and 22, respectively.
- the surface layer portion includes a surface and a predetermined thickness from the surface.
- Examples of water repellents include silicon-based water repellents, fluorine-based water repellents, paraffin-based water repellents (wax), vegetable oils, animal oils, and mineral oils. A water repellent or a fluorine-based water repellent is preferred.

- the urine absorbed in the first pulp layer 12 and the second pulp layer 13 is delayed in the absorption of the third pulp layer 15 by the water repellent surface layer portion 14 of the second pulp layer 13. 12 and the second pulp layer 13 are dispersed throughout.
- the urine transmitted through the hole 24 reaches the third pulp layer 15 and is absorbed by the third pulp layer 15. Further, urine that has passed through the water-repellent surface layer portion 14 of the second pulp layer 13 is absorbed by the third pulp layer 15. The urine that has reached the third pulp layer 15 is delayed in the absorption of the fourth pulp layer 17 by the water-repellent surface layer portion 16 of the third pulp layer 15 and is further dispersed throughout the third pulp layer 15 during this time. .

- the water repellent applied to the pulp layer will penetrate into the inside due to capillary action. In this case, the liquid does not penetrate into the gaps between the fibers, and therefore does not hydrolyze.
- the fiber density of the pulp layer is low and the pulp layer is thick, the water repellent applied to the pulp layer remains on the surface layer. In this case, the liquid penetrates into the gaps between the fibers. Therefore, it is desirable that the pulp layer has such a thickness that the water repellent does not penetrate from the coated surface to the opposite surface when the minimum water repellent that can be controlled by spraying is applied, for example. .
- the absorbent article 10 when the absorbent article 10 is immersed in an appropriate amount of water, the water permeates the first pulp layer 12 to the sixth pulp layer 21 and separates the entanglement of fibers constituting these layers.
- the water-repellent surface layer provided in the pulp layer has a function to bind the pulp layer, it does not have a very strong binding force, so it binds with a water repellent as the pulp layer collapses.
- the fibers that had been separated are also separated. Thereby, the absorbent article 10 disintegrates rapidly (for example, within 10 seconds) with an appropriate amount of water. For this reason, even if the absorbent article 10 is poured into a flush toilet, there is no risk of clogging of toilet piping.
- the absorbent article 10 is further processed to give an additional function.

- the joining process is the same as the joining process described in the first embodiment.
- a cutting step of the absorbent article 500 or the like may be performed as appropriate.
- the surface sheet layer 511 is piled with pulverized pulp to form the first pulp layer 512, and a water repellent is applied to the formed first pulp layer 512 and dried to form the water repellent surface layer portion 513.
- pulverized pulp is further stacked on the water repellent surface layer 513 to form the second pulp layer 514, and a water repellent is applied to the formed second pulp layer 514 and dried to form the water repellent surface layer 515.
- a water repellent may be applied after a binder is applied to the pulp layer and dried to fix the pulp layer.
- the binder is not particularly limited as long as it has a predetermined adhesive force and can impart a predetermined strength to the pulp layer, and various binders are used.
- the binder include polysaccharide derivatives, natural polysaccharides, and synthetic polymers.
- a crosslinking agent may be used to improve the physical strength of the binder. Note that specific examples of the polysaccharide derivative, the natural polysaccharide, the synthetic polymer, and the binder are the same as those in the first embodiment, and thus the description thereof is omitted.
- the absorbent article 500 of the present embodiment includes the top sheet layer 511 having water decomposability, the first pulp layer 512 and the second pulp layer 514 made of cotton-like pulverized pulp, and the first
- a water repellent to the non-skin surface side surface portions of the first pulp layer 512 and the second pulp layer 514 to form the water repellent surface layer portions 513 and 515
- the liquid absorbed from the skin surface is transferred to the non-skin surface. Since the penetration is suppressed and the liquid is dispersed in the first pulp layer 512 and the second pulp layer 514, the absorbent article 500 does not collapse even if it absorbs a small amount of liquid.
- the absorbent article 500 when the absorbent article 500 is immersed in an appropriate amount of water, the absorbent article 500 can be rapidly collapsed, and even if the absorbent article 500 is poured into the toilet, the toilet piping is not clogged.
- FIG. 9 is a conceptual diagram showing a state before the absorbent article 500 is laminated in the sixth embodiment.
- the first pulp layer 521 is not coated with a water repellent, but the second pulp layer 522 has a water repellent on both the skin surface side and the non-skin surface side. It has been applied.
- the water repellent surface layer portion 524 on the non-skin surface side is coated with more water repellent than the water repellent surface layer portion 523 on the skin surface side.
- the absorbent article 500 can be formed by laminating the first pulp layer 521 and the second pulp layer 522, and the surface sheet layer 511, and subjecting the laminate to pressing treatment and joining treatment.
- the said Embodiment 5 and 6 demonstrated that the application quantity of the water repellent applied to the 2nd pulp layer 514 was made larger than the quantity applied to the 1st pulp layer 512, this invention is not limited to this. That is, the amount of water repellent applied to the second pulp layer 514 may be the same as or less than the amount applied to the first pulp layer 512.
- the absorbent article 500 demonstrated the case where the surface sheet layer 511, the 1st pulp layer 512, and the 2nd pulp layer 514 were laminated
- the absorbent article may be a laminate in which two layers each having a top sheet layer 511 and a first pulp layer 512 are laminated.
