The top sheet 30 has a property of transmitting liquid, and examples thereof include a porous or non-porous nonwoven fabric, a porous plastic sheet, and the like. Of these, the nonwoven fabric is not particularly limited as to what the raw fiber is. For example, synthetic fibers such as olefins such as polyethylene and polypropylene, polyesters and polyamides, recycled fibers such as rayon and cupra, natural fibers such as cotton, and mixed fibers and composite fibers using two or more of them. Etc. can be illustrated. Furthermore, the nonwoven fabric may be manufactured by any processing. Examples of the processing method include known methods such as a spunlace method, a spunbond method, a thermal bond method, a melt blown method, a needle punch method, an air through method, and a point bond method. For example, if the flexibility and drapeability are to be obtained, the spunbond method and the spunlace method are preferable processing methods, and if the bulkiness and softness are to be obtained, the air-through method, the point bond method, and the thermal bond method are preferable processing methods. .

The basis weight is measured as follows. After the sample or test piece has been pre-dried, it is left in a test room or apparatus in a standard state (test location is temperature 20 ± 5 ° C., relative humidity 65% or less) to obtain a constant weight. Pre-drying refers to making a sample or test piece constant in an environment where the relative humidity is 10 to 25% and the temperature does not exceed 50 ° C. In addition, it is not necessary to perform preliminary drying about the fiber whose official moisture content is 0.0%. A sample with a size of 200 mm × 250 mm (± 2 mm) is cut out from the test piece in a constant weight using a rice-basis plate (200 mm × 250 mm, ± 2 mm).

The laminated sheet etc. which overlap | superposed and joined etc. can be illustrated. For the liquid-impermeable sheet 11, it is preferable to use a liquid-impervious and moisture-permeable material that has been preferred in recent years from the viewpoint of preventing stuffiness. As a plastic film having moisture permeability, a microporous plastic film obtained by kneading an inorganic filler in an olefin resin such as polyethylene or polypropylene, forming a sheet, and then stretching in a uniaxial or biaxial direction. Is widely used. In addition, non-woven fabric using micro-denier fibers, leakproof reinforcement by reducing the voids of the fibers by applying heat or pressure, and methods such as applying a superabsorbent resin or hydrophobic resin or water repellent Thus, a sheet that is liquid-impermeable without using a plastic film can also be used as the liquid-impermeable sheet 11.

吸収体５６には、その一部又は全部に高吸収性ポリマー粒子を含有させることができる。高吸収性ポリマー粒子とは、「粒子」以外に「粉体」も含む。高吸収性ポリマー粒子の粒径は、この種の吸収性物品に使用されるものをそのまま使用でき、１０００μｍ以下、特に１５０〜４００μｍのものが望ましい。高吸収性ポリマー粒子の材料としては、特に限定無く用いることができるが、吸水量が４０ｇ／ｇ以上のものが好適である。高吸収性ポリマー粒子としては、でんぷん系、セルロース系や合成ポリマー系などのものがあり、でんぷん−アクリル酸（塩）グラフト共重合体、でんぷん−アクリロニトリル共重合体のケン化物、ナトリウムカルボキシメチルセルロースの架橋物やアクリル酸（塩）重合体などのものを用いることができる。高吸収性ポリマー粒子の形状としては、通常用いられる粉粒体状のものが好適であるが、他の形状のものも用いることができる。 (Superabsorbent polymer particles)
The absorber 56 can contain superabsorbent polymer particles in a part or all thereof. Superabsorbent polymer particles include “powder” in addition to “particles”. As the particle diameter of the superabsorbent polymer particles, those used in this type of absorbent article can be used as they are, and those having a particle size of 1000 μm or less, particularly 150 to 400 μm are desirable. The material of the superabsorbent polymer particles can be used without any particular limitation, but those having a water absorption of 40 g / g or more are suitable. High-absorbent polymer particles include starch-based, cellulose-based, and synthetic polymer-based starch-acrylic acid (salt) graft copolymers, saponified starch-acrylonitrile copolymers, and sodium carboxymethylcellulose crosslinks. Or an acrylic acid (salt) polymer can be used. As the shape of the superabsorbent polymer particles, a commonly used granular material is suitable, but other shapes can also be used.

高吸収性ポリマー粒子としては、吸水速度が４０秒以下のものが好適に用いられる。吸水速度が４０秒を超えると、吸収体５６内に供給された液が吸収体５６外に戻り出てしまう所謂逆戻りを発生し易くなる。   As the superabsorbent polymer particles, those having a water absorption rate of 40 seconds or less are preferably used. When the water absorption speed exceeds 40 seconds, so-called reversion in which the liquid supplied into the absorber 56 returns to the outside of the absorber 56 is likely to occur.

また、高吸収性ポリマー粒子としては、ゲル強度が１０００Ｐａ以上のものが好適に用いられる。これにより、嵩高な吸収体５６とした場合であっても、液吸収後のべとつき感を効果的に抑制できる。なお、ゲル強度とは、次のようにして測定されるものである。人工尿４９．０ｇに、高吸収性ポリマーを１．０ｇ加え、スターラーで攪拌させる。生成したゲルを４０℃×６０％ＲＨの恒温恒湿槽内に３時間放置したあと常温にもどし、カードメーター（Ｉ．ｔｅｃｈｎｏ Ｅｎｇｉｎｅｅｒｉｎｇ社製：Ｃｕｒｄｍｅｔｅｒ−ＭＡＸ ＭＥ−５００）でゲル強度を測定する。   Further, as the superabsorbent polymer particles, those having a gel strength of 1000 Pa or more are preferably used. Thereby, even if it is a case where it is set as the bulky absorber 56, the sticky feeling after liquid absorption can be suppressed effectively. The gel strength is measured as follows. Add 1.0 g of superabsorbent polymer to 49.0 g of artificial urine and stir with a stirrer. The produced gel is left in a constant temperature and humidity chamber of 40 ° C. × 60% RH for 3 hours and then returned to room temperature, and the gel strength is measured with a card meter (Curdmeter-MAX ME-500, manufactured by I.techno Engineering).

高吸収性ポリマー粒子の目付け量は、当該吸収体５６の用途で要求される吸収量に応じて適宜定めることができる。したがって一概には言えないが、５０〜３５０ｇ／ｍ2とすることができる。ポリマーの目付け量が５０ｇ／ｍ2未満では、吸収量を確保し難くなる。３５０ｇ／ｍ2を超えると、効果が飽和する。 The basis weight of the superabsorbent polymer particles can be appropriately determined according to the amount of absorption required for the use of the absorber 56. Therefore, although it cannot be said unconditionally, it can be set to 50 to 350 g / m 2 . If the amount of polymer is less than 50 g / m 2, it is difficult to secure the absorption amount. When it exceeds 350 g / m 2 , the effect is saturated.

（包装シート）
包装シート５８は、ティッシュペーパ、特にクレープ紙、不織布、ポリラミ不織布、小孔が開いたシート等を用いることができる。ただし、高吸収性ポリマー粒子が抜け出ないシートであるのが望ましい。クレープ紙に換えて不織布を使用する場合、親水性のＳＭＳ不織布（ＳＭＳ、ＳＳＭＭＳ等）が特に好適であり、その材質はポリプロピレン、ポリエチレン／ポリプロピレン複合材などを使用できる。目付けは、５〜４０ｇ／ｍ2、特に１０〜３０ｇ／ｍ2のものが望ましい。 (Packaging sheet)
As the packaging sheet 58, tissue paper, particularly crepe paper, non-woven fabric, polylaminated non-woven fabric, a sheet having small holes, or the like can be used. However, it is desirable that the superabsorbent polymer particles be a sheet that does not escape. When a nonwoven fabric is used in place of the crepe paper, a hydrophilic SMS nonwoven fabric (SMS, SSMMS, etc.) is particularly suitable, and the material can be polypropylene, polyethylene / polypropylene composite material, or the like. The basis weight is preferably 5 to 40 g / m 2 , particularly 10 to 30 g / m 2 .

＜外装体の製造方法＞
（第１製造方法）
次に、第１製造方法について説明する。なお、外装体１２を形成する背側シート２０の製造方法と腹側シート２１の製造方法は、同一製造方法であるので、以下では、背側シート２０の製造方法を例にとって説明し、腹側シート２１の製造方法の説明は省略する。 <Method for manufacturing exterior body>
(First manufacturing method)
Next, the first manufacturing method will be described. In addition, since the manufacturing method of the back side sheet | seat 20 which forms the exterior body 12, and the manufacturing method of the abdominal side sheet | seat 21 are the same manufacturing methods, hereafter, the manufacturing method of the back side sheet | seat 20 is demonstrated to an example, and an abdominal side sheet | seat is demonstrated. The description of the manufacturing method 21 is omitted.

図７に示すように、背側シート２０の第１シート２０Ｂの外面と第２シート２０Ｃの内面の間には、上下方向に所定の間隔Ａを隔てて左右方向に延在する複数のウエスト縁部弾性伸縮部材１７が挟持されている。ウエスト縁部弾性伸縮部材１７の左右方向の両側部は、第１シート２０Ｂと第２シート２０Ｃの両側部をヒートシール等で接合する接合部２５に固定されている。一方、ウエスト縁部弾性伸縮部材１７の中間部、すなわち、両側部を除く部位は、第１シート２０Ｂの外面と第２シート２０Ｃの内面に固定されておらず、自由に左右方向に伸縮することができる。   As shown in FIG. 7, between the outer surface of the first sheet 20B of the back seat 20 and the inner surface of the second sheet 20C, a plurality of waist edges extending in the left-right direction with a predetermined interval A in the up-down direction. A partial elastic elastic member 17 is sandwiched. Both side portions in the left-right direction of the waist edge elastic elastic member 17 are fixed to a joint portion 25 that joins both side portions of the first sheet 20B and the second sheet 20C by heat sealing or the like. On the other hand, the middle portion of the waist edge elastic elastic member 17, that is, the portion excluding both side portions is not fixed to the outer surface of the first sheet 20B and the inner surface of the second sheet 20C, and freely expands and contracts in the left-right direction. Can do.

第１シート２０Ｂの外面と第２シート２０Ｃの内面は、上下方向に隣接するウエスト縁部弾性伸縮部材１７，１７の一側のウエスト縁部弾性伸縮部材１７の上側に、熱融着や超音波シールによって形成された左右方向に所定の間隔を隔てて設けられた第１結合部２６と、上下方向に隣接するウエスト縁部弾性伸縮部材１７，１７の一側のウエスト縁部弾性伸縮部材１７の下側に、熱融着や超音波シールによって形成された左右方向に所定の間隔Ｂを隔てて設けられた第２結合部２７によって固定されている。なお、図７の左右方向が上述した幅方向に一致し、上下方向が上述した前後方向に一致する。   The outer surface of the first sheet 20 </ b> B and the inner surface of the second sheet 20 </ b> C are heat-sealed or ultrasonically disposed on the upper side of the waist edge elastic elastic member 17 on one side of the waist edge elastic elastic members 17, 17 adjacent in the vertical direction. The first coupling portion 26 provided at a predetermined interval in the left-right direction formed by the seal, and the waist edge elastic elastic member 17 on one side of the waist edge elastic elastic members 17, 17 adjacent in the vertical direction. It is fixed to the lower side by a second coupling portion 27 provided at a predetermined interval B in the left-right direction formed by heat fusion or ultrasonic sealing. In addition, the left-right direction of FIG. 7 corresponds to the width direction mentioned above, and the up-down direction corresponds to the front-back direction mentioned above.

これにより、図８に示すように、上下方向に所定の間隔を隔てて設けられたウエスト縁部弾性伸縮部材１７の収縮力によって、第１シート２０Ｂの内側に、平面視において略ひし形形状の襞２８が形成され、同様に第２シート２０Ｃの外面には、平面視において略ひし形形状の襞２８が形成されて装着時における触感性能、外観性能を高めることができる。また、図９に示すように、第１シート２０Ｂの内面に形成される断面形状において略山形形状の襞２８は、隣接する結合部２６Ａ等の間に対向する部位が頂部２８Ａを形成し、結合部２６Ａに対向する部位が基部２８Ｂを形成する。なお、本明細書においてひし形形状とは、上下方向の対角線が左右方向の対角線よりも長く、上下方向に位置する角が左右方向において同一位置にある形状を言う。   As a result, as shown in FIG. 8, a substantially rhombus-shaped ridge in the plan view is formed on the inner side of the first sheet 20B by the contraction force of the waist edge elastic elastic member 17 provided at a predetermined interval in the vertical direction. Similarly, a substantially rhombus-shaped collar 28 is formed on the outer surface of the second sheet 20C in plan view, so that the tactile sensation performance and the appearance performance during mounting can be enhanced. Further, as shown in FIG. 9, in the cross-sectional shape formed on the inner surface of the first sheet 20B, the substantially chevron-shaped ridge 28 has a top portion 28A formed between the adjacent coupling portions 26A, etc. A portion facing the portion 26A forms a base portion 28B. In the present specification, the rhombus shape means a shape in which the diagonal line in the vertical direction is longer than the diagonal line in the horizontal direction and the corners positioned in the vertical direction are in the same position in the horizontal direction.

上下方向に隣接するウエスト縁部弾性伸縮部材１７，１７の間隔Ａは、５〜１０ｍｍに設定するのが好適である。間隔Ａが５ｍｍ未満の場合は、ウエスト縁部弾性伸縮部材１７の収縮力によって形成される襞２８の大きさが小さく、襞２８で区画される空間２８Ｃの容積が小さくクッション性能が小さく装着性能が低下する恐れがあり、また、ウエスト縁部弾性伸縮部材１７の両側部を接合部２５で固定する効率が低下する恐れがある。一方、間隔Ａが１０ｍｍ超の場合には、ウエスト縁部弾性伸縮部材１７の収縮力によって形成される襞２８が、つぶれて外観性能を低下させる恐れがある。また、本実施形態にあっては、間隔Ａを９ｍｍに設けて製造している。   The interval A between the waist edge elastic elastic members 17 and 17 adjacent in the vertical direction is preferably set to 5 to 10 mm. When the distance A is less than 5 mm, the size of the collar 28 formed by the contraction force of the waist edge elastic elastic member 17 is small, the volume of the space 28C defined by the collar 28 is small, the cushion performance is small, and the mounting performance is small. There is a fear that the efficiency of fixing both side portions of the waist edge elastic elastic member 17 with the joint portion 25 may be reduced. On the other hand, when the distance A is more than 10 mm, the heel 28 formed by the contraction force of the waist edge elastic elastic member 17 may be crushed and deteriorate the appearance performance. Moreover, in this embodiment, it manufactures by providing the space | interval A at 9 mm.

第１結合部２６は、一側のウエスト縁部弾性伸縮部材１７の上側に、上下方向に隣接するウエスト縁部弾性伸縮部材１７，１７の間隔Ａの１／２の間隔Ｂを隔てて設けられている。また、第１結合部２６は、左右方向に所定の第１間欠間隔Ｃ１を隔てて設けられた左右方向に直線状に延在する複数の第１結合部位２６Ａから形成され、第１間欠間隔Ｃ１は、第１結合部位２６Ａの左右方向の第１長さＤ１と同一長さに設定されている。   The first coupling portion 26 is provided on the upper side of the waist edge elastic elastic member 17 on one side with a distance B that is 1/2 of the interval A between the waist edge elastic elastic members 17 and 17 adjacent in the vertical direction. ing.
