Description

[Technical Field]

[0001] The present invention relates to an absorbent article comprising a highly absorbent sheet. [Background technology]

[0002] Generally, absorbent articles are composed of a liquid-permeable top sheet, a liquid-impermeable back sheet, and an absorbent body disposed between the top sheet and the back sheet, so that bodily fluids such as urine pass through the top sheet and are absorbed by the absorbent body.

[0003] If an absorbent article is thick or heavy, it will be uncomfortable to wear. Therefore, thin absorbent articles are desired, but when designing thin absorbent articles, consideration is usually given to reducing the thickness of the absorbent body, which accounts for the majority of the absorbent article.

[0004] Various embodiments of absorbent articles using thin absorbents have been proposed. For example, Patent Document 1 discloses an absorbent core having a substrate layer having a first surface and a second surface, an absorbent polymer material layer having a first surface and a second surface, and an adhesive layer having a first surface and a second surface, the absorbent polymer material layer being contained between the adhesive layer and the substrate layer, the second surface of the absorbent polymer material layer contacting the first surface of the substrate layer, and the first surface of the absorbent polymer material layer contacting the second surface of the adhesive layer, the substrate layer being provided with a foam material layer, and by incorporating a foam layer containing an absorbent gelling material in a layer stably attached to the substrate layer, the absorbent article has a good fit, is comfortable, and can maintain the utilization rate of the core's absorption capacity.

[0006] However, when making absorbent articles thinner and lighter in the above manner to improve wearing comfort, it is necessary to sacrifice a certain degree of absorption performance (absorption amount during repeated absorption, absorption speed, leakage, etc.) In particular, incontinence products and urine absorption pads with a small absorbent core area cannot maintain sufficient absorption performance, which has led to the problem of body fluids easily leaking from the front, back, or left and right edges.

[0007] The present invention has been made in view of the above circumstances, and has as its object to provide an absorbent article that has little leakage from the edges, and that has good absorbency and is comfortable to wear. [Means for solving the problem]

[0010] (2) A second aspect of the present invention is an absorbent article as described in (1), characterized in that the highly absorbent sheets arranged at the front and rear longitudinal ends of the absorbent body are approximately rectangular, and the highly absorbent sheets arranged at both front and rear end ends of the absorbent body are approximately trapezoidal and facing the widthwise center of the absorbent article.

[0011] (3) A third aspect of the present invention is an absorbent article according to (1) or (2), characterized in that the spacing between adjacent superabsorbent sheets in a flat state is 5 mm or more and 50 mm or less at the closest points.

[0016] Hereinafter, a mode for carrying out the present invention (hereinafter simply referred to as "the present embodiment") will be described in detail. The following present embodiment is an example for explaining the present invention, and is not intended to limit the present invention to the following content. The present invention can be carried out by appropriately modifying it within the scope of its gist. In the drawings, the same elements are denoted by the same reference numerals, and redundant explanations will be omitted. Furthermore, unless otherwise specified, the positional relationships, such as up, down, left, and right, are based on the positional relationships shown in the drawings. Furthermore, the dimensional ratios of the drawings are not limited to those shown in the drawings.

[0017] In the description of this specification, "wearing the absorbent article 1" refers to at least one of the state when the absorbent article 1 is worn and the state after it has been worn. The longitudinal direction of the absorbent article 1 is the direction extending from the front to the back of the wearer when the absorbent article 1 is worn, and is the direction indicated by the symbol X in the drawings. The width direction of the absorbent article 1 is the direction transverse to or perpendicular to the longitudinal direction, and is the direction indicated by the symbol Y in the drawings. Furthermore, the "skin-contacting surface" refers to the surface of each component, such as the absorbent body, that faces the wearer's skin when worn, and the "non-skin-contacting surface" refers to the surface of each component, such as the absorbent body, that faces away from the wearer's skin when worn. Body fluids refer to liquids excreted from the body to the outside, such as urine and water in loose stools. Furthermore, examples of the absorbent article 1 include incontinence products and urine absorption pads, and although large urine absorption pads are particularly preferred, the absorbent article 1 is not limited thereto and may be other absorbent articles.

[0018] <Absorbent articles> Fig. 1 is a plan view of an absorbent article 1 according to an embodiment of the present invention, as viewed from the top sheet 10 side. Also, Figs. 2, 3, and 4 are cross-sectional views taken along lines Y1-Y1, Y2-Y2, and X1-X1 in Fig. 1, respectively. As shown in Figs. 1 to 4, the absorbent article 1 comprises a liquid-permeable top sheet 10, a liquid-impermeable back sheet 20, and an absorbent body 30 disposed between the top sheet 10 and the back sheet 20. The absorbent body 30 includes an absorbent body main body 31 and a highly absorbent sheet 32 disposed on the skin-contacting surface side of the absorbent body main body 31. This results in a structure in which the absorbent body 30 is sandwiched between the top sheet 10 and the back sheet 20.

[0019] The longitudinal dimension of the absorbent article 1 is preferably 200 mm to 800 mm, and the width dimension is preferably 80 mm to 500 mm. By adjusting the dimensions of the absorbent article 1 to fall within the above ranges, an absorbent article 1 suitable for use as an incontinence product, a urine absorption pad, etc. can be obtained.

[0020] <Top sheet> The top sheet 10 may be formed from a liquid-permeable substrate that allows bodily fluids to move into the absorbent body 30, and may be, for example, a known hydrophilic nonwoven fabric such as a thermal-bonded nonwoven fabric or a spun-bonded nonwoven fabric. Furthermore, the surface of the top sheet 10 may be embossed or perforated to improve liquid permeability. Any known method can be used for embossing or perforating the top sheet 10 without limitation. Furthermore, to reduce irritation to the skin, the top sheet 10 may contain lotions, antioxidants, anti-inflammatory ingredients, pH adjusters, antibacterial agents, moisturizers, and the like. From the viewpoints of strength, processability, and liquid return, the basis weight of the top sheet 10 is 15 g / m 2 More than 200g / m 2 Preferably, it is 20 g / m or less. 2 More than 80g / m 2 The following is more preferable: There are no particular restrictions on the shape of the top sheet 10, as long as it has a shape that covers the absorbent body 30 and is necessary to guide bodily fluids to the absorbent body 30 without leakage.

[0021] <Back seat> The backsheet 20 may be formed using a liquid-impermeable substrate that prevents the body fluids held by the absorbent body 30 from wetting clothing, and a breathable or non-breathable, liquid-impermeable plastic film may be used.

[0022] From the viewpoint of strength and processability, the basis weight of the back sheet 20 is 15 g / m 2 More than 40g / m 2 Preferably, it is 18 g / m or less. 2 More than 30g / m 2 The following is more preferable: To provide breathability to the back sheet 20, for example, a filler may be blended into the resin film of the base material, or the back sheet 20 may be embossed. An example of the filler is calcium carbonate, and the blending method may be any known method without limitation.

[0023] <3D gathers> As shown in Fig. 1, the absorbent article 1 may further include a pair of three-dimensional gathers 40 along the longitudinal direction on the skin contact surface side of the top sheet 10 in order to prevent leakage of bodily fluids excreted by the wearer to the left and right (side leakage). The pair of three-dimensional gathers 40 is arranged so that the outer ends of the pair of three-dimensional gathers 40 in the width direction of the absorbent article 1 are fixed to the back sheet 20, the inner ends are fixed to the top sheet 10, and the center is a free end that is not fixed to the top sheet 10. By providing the pair of three-dimensional gathers 40 along the longitudinal direction, the pair of three-dimensional gathers 40 have the ability to stand up and can be deformed to fit the body shape of the wearer. From the standpoints of strength and processability, the basis weight of the pair of three-dimensional gathers 40 is set to 10 g / m 2 More than 100g / m 2 It is preferable that:

[0024] <Absorbent> In the absorbent article 1 of the present invention, the longitudinal dimension of the absorber 30 is preferably 150 mm to 700 mm, more preferably 200 mm to 650 mm, and the width dimension of the absorber 30 is preferably 50 mm to 450 mm, more preferably 70 mm to 400 mm.

[0025] (Highly absorbent sheet) As described above, the absorbent body 30 includes an absorbent body main body 31 and a highly absorbent sheet 32 arranged on the skin-contacting side of the absorbent body main body 31. As shown in FIG. 1, the highly absorbent sheet 32 is arranged in seven layers, including a central highly absorbent sheet 320 arranged in the center of the absorbent body main body 31, a front end highly absorbent sheet 321 and a rear end highly absorbent sheet 322 arranged at the front and rear longitudinal ends of the absorbent body main body 31, and a front side end highly absorbent sheet 323 and a rear side end highly absorbent sheet 324 arranged at the front and rear end ends of the absorbent body main body 31, respectively. Furthermore, the front end high-absorbency sheet 321 and the rear end high-absorbency sheet 322 at the front and rear longitudinal ends of the absorbent body 31, and the front side end high-absorbency sheets 323 and the rear side end high-absorbency sheets 324 at both front and rear ends of the absorbent body 31, are arranged flat and spaced apart from each other. In this way, the high-absorbency sheet 32 is arranged on the skin-contacting surface of the absorbent body 31 and spaced apart at the center, front and rear ends, and left and right ends (both front and rear ends) of the absorbent article 1, so that the absorbent body 30 is provided over the entire surface of the absorbent article 1, improving leakproofness (leak prevention). Furthermore, by arranging the high-absorbency sheets 32 at the center, front and rear ends, and left and right ends of the absorbent article 1 at intervals such that they do not come into contact with each other, the thickness and weight of the absorbent body 30 can be distributed, improving wearing comfort.

[0026] Furthermore, when the absorbent article 1 assumes a three-dimensional state when worn, adjacent ones of the super absorbent sheets 32 approach each other without overlapping, forming a substantially continuous belt-like absorbent sheet. That is, as the super absorbent sheets 32 are each lifted toward the center of the absorbent article 1 (the absorbent article 1 curves along the buttocks of the wearer), the six separate sheets of the super absorbent sheet 32 other than the central super absorbent sheet 320 approach each other and form a substantially continuous belt-like shape. By providing the high-absorbency sheet 32 with such a structure, the central portion of the absorber 30 can absorb a large amount of urine at one time, or even urination that has already been absorbed multiple times, improving the repeated absorption and diffusibility of urine, while effectively preventing seepage and leakage of urine that has diffused due to repeated absorption of urination at the outer edge of the absorber 30, and providing an absorbent article 1 that is soft to the touch both before and after urine absorption and is comfortable to wear. Furthermore, even if the absorber 30 provided in the absorbent article 1 of the present invention is thin, it is possible to provide an absorbent article 1 that is excellent in absorbency, such as repeated absorption speed and diffusibility, and prevention of leakage from the edges, and is comfortable to wear both before and after urination.

[0027] It is preferable that the front end high absorbency sheet 321 and the rear end high absorbency sheet 322 arranged at the front and rear longitudinal ends of the absorbent body 31 are both approximately rectangular, and the front side end high absorbency sheet 323 and the rear side end high absorbency sheet 324 arranged at both front and rear ends of the absorbent body 31 are both approximately trapezoidal and oriented toward the widthwise center of the absorbent article 1. By giving each of the high absorbency sheets 32 the above-described shape, leakage from the front and rear ends and the left and right ends of the absorbent article 1 can be more effectively prevented.

[0028] Furthermore, in order for the high-absorbency sheets 32 to be arranged spaced apart from one another in a flat state and for adjacent high-absorbency sheets 32 to be close to one another without overlapping when the absorbent article 1 assumes a three-dimensional state when worn, and to form a substantially continuous band-like absorbent sheet, it is preferable that the spacing between adjacent high-absorbency sheets 32 in a flat state be 5 mm or more and 50 mm or less at the closest point. Furthermore, the front end high absorbency sheet 321 and the rear end high absorbency sheet 322 arranged at the front and rear longitudinal ends of the absorbent body 31, and the front side end high absorbency sheet 323 and the rear side end high absorbency sheet 324 arranged at both front and rear ends of the absorbent body 31, form a substantially continuous belt-shaped absorbent sheet at the longitudinal outer edge and width outer edge of the absorbent body 31. Almost continuous band-shaped short axis It is preferable that the length in the direction is 10 mm or more and 100 mm or less.

[0029] The dimensions of each of the high-absorbency sheets 32 depend on the shape of each of the high-absorbency sheets 32, the spacing between the high-absorbency sheets 32 in a planar state, and the size of the high-absorbency sheets 32 when they are formed into a substantially continuous belt-shaped absorbent sheet. Approximately continuous band-shaped short axis There are no particular limitations on the dimensions as long as they can satisfy the length in the direction.

[0030] Furthermore, as shown in the cross-sectional view of Figure 5, the highly absorbent sheet 32 preferably comprises two layers of sheet 33 and a highly absorbent polymer 34 enclosed between the sheets 33, and the sheet 33 is preferably a composite nonwoven fabric in which a pulp fiber web is laminated and integrated onto a polyurethane continuous porous body sheet and / or a spunbond nonwoven fabric.

[0031] The polyurethane continuous porous sheet used for the sheet 33 may be a single-layer sheet of urethane foam, but it is preferable that the skeleton surface is hydrophilic. The polyurethane continuous porous sheet has a basis weight of 30 g / m 2 More than 300g / m 2 and the apparent density is preferably 100 kg / m or less. 3 More than 200kg / m 3 It is preferable that:

[0032] On the other hand, when the sheet 33 is a composite nonwoven fabric, it is preferable that the material of the spunbond nonwoven fabric is one or a combination of two or more selected from the group consisting of nylon, vinylon, polyester, acrylic, polyethylene, polypropylene, and polystyrene. In addition, the basis weight of the spunbond nonwoven fabric is 7 g / m 2 More than 20g / m 2 Hereinafter, the basis weight of the pulp fiber web is 30 g / m 2 More than 70g / m 2 The weight ratio of the spunbond nonwoven fabric to the pulp fiber web is preferably 40 / 60 wt % or more and 10 / 90 wt % or less.

[0033] In this case, in the hydroentanglement step in which the spunbond nonwoven fabric and the pulp fiber web are hydroentangled to integrate them, it is preferable that the hole diameter Φ of the water jet nozzle that sprays the water jet be 0.06 mm or more and 0.15 mm or less, and that the spacing between the water jet nozzles be 0.4 mm or more and 1.0 mm or less. It is also preferable that the surface of the composite nonwoven fabric that comes into contact with the superabsorbent polymer 34 be the surface that has been hydroentangled by the water jet. By setting the hole diameter and spacing of the water jet nozzle within the above numerical ranges and bringing the hydroentangled surface into contact with the superabsorbent polymer 34, the unevenness formed by the water jet on the hydroentangled surface can make it less likely that the superabsorbent polymer 34 will shift or move. In addition, it is preferable that the strength of the composite nonwoven fabric in a tensile test is such that the force required to stretch a 25 mm wide test piece by 2 mm in the longitudinal direction in a Tensilon test is 1.5 N / 25 mm or more and 5.0 N / 25 mm or less.

[0034] The superabsorbent polymer 34 contained in the superabsorbent sheet 32 is not particularly limited as long as it can absorb body fluids and prevent backflow, and materials formed from sodium polyacrylate, polyaspartate, (starch-acrylic acid) graft copolymer, (acrylic acid-vinyl alcohol) copolymer, (isobutylene-maleic anhydride) copolymer, and saponified materials thereof can be used. Among these, sodium polyacrylate is preferred from the viewpoint of absorption capacity per weight. The basis weight of the superabsorbent polymer 34 is 30 g / m. 2 More than 300g / m 2 It is preferable that:

[0035] By including a composite nonwoven fabric in which a pulp fiber web is laminated and integrated onto a polyurethane continuous porous sheet and / or a spunbond nonwoven fabric, and a superabsorbent polymer 34, the absorbent body 30 can be made even thinner, and particularly when the absorbent article 1 is a large urine pad with a high absorption capacity, it is possible to achieve high levels of absorption speed and return, while also achieving good diffusion, absorbency, and wearing comfort. It is preferable that at least one of the sheets 33 included in the central high-absorbency sheet 320 is a composite nonwoven fabric, more preferably the sheet 33 on the side not in contact with the wearer's skin is a composite nonwoven fabric, and even more preferably both sheets 33 are composite nonwoven fabrics. It is also preferable that at least one of the sheets 33 included in each of the front end high-absorbency sheet 321, rear end high-absorbency sheet 322, front side end high-absorbency sheet 323, and rear side end high-absorbency sheet 324 is a continuous porous polyurethane sheet, it is more preferable that the sheet 33 on the side not in contact with the wearer's skin is a continuous porous polyurethane sheet, and even more preferably both sheets 33 are continuous porous polyurethane sheets. By selecting the materials for each of the high-absorbency sheets 32 in this way, it is possible to obtain an absorbent article 1 that does not decrease in absorption rate during repeated absorption, has a small amount of backflow, and is excellent in diffusing urine.

[0036] (Absorbent body) The absorbent body 31 comprises two layers of sheets and a superabsorbent polymer enclosed between the sheets, similar to the superabsorbent sheet 32 shown in Fig. 5, and the sheet is preferably a composite nonwoven fabric formed by laminating and integrating a pulp fiber web onto a polyurethane continuous porous body sheet and / or a spunbond nonwoven fabric (not shown). The polyurethane continuous porous body sheet, composite nonwoven fabric, and superabsorbent polymer used in the absorbent body 31 can be the same as those used in the superabsorbent sheet 32 described above.

[0037] Furthermore, to prevent slippage of the highly absorbent sheet 32 and stabilize the shape of the absorbent body 30, carrier sheets (not shown) may be provided on the top and bottom of the absorbent body 30 (on the skin-contacting side of the highly absorbent sheet 32 and / or on the non-skin-contacting side of the absorbent body main body 31). The substrate of the carrier sheet may be any hydrophilic material, and examples of such substrates include tissue, absorbent paper, and hydrophilic nonwoven fabrics such as air-laid nonwoven fabrics. When multiple carrier sheets are provided, the substrates of the multiple carrier sheets may be the same or different.

[0038] 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 apparent to those skilled in the art that various modifications and improvements can be made to the above embodiments. Furthermore, it is clear from the claims that such modifications and improvements can also be included within the technical scope of the present invention. [Example]
