式 方 施 實施發明用的形態 以下針對本發明的吸收性物品部進行詳細説明。 本發明的吸收性物品部，雖以具有：約45 %以下的保 溫率；與約1 0質量％以下的再潤濕率作爲特徴，可是， 依據本案發明者們藉由將吸收性物品的保溫率設在約45% 以下，且將再潤濕率設在約1 〇質量％以下的方式，找到 在穿用時不易悶熱，而且吸收排泄物之後依然乾爽者。 上述保溫率是可如以下方式進行測量。 (1 )準備日本加多技術株式會社製，KES-F7精密迅 速熱物性測量裝置散熱器（THERMOLAB ) II，將室溫調 整到20°C，並且將濕度調整到60%RH。 201233374 (2 )測量用後即棄式紙尿布的保溫率時，以排泄口 抵接域的中心爲中心，剪下長方向12 cm及正交於長方向 的方向（以下有僅將正交於長方向的方向稱爲「正交方 向」的時候）12 cm的試料。 測量生理用衛生棉時，由於一般要確保1 2 c m X 1 2 c m 的試料很難，所以，以排泄口抵接域的中心爲中心，剪下 長方向8cm及正交方向8cm的試料》 (3) 將上述試料以雙面帶黏貼於在散熱器Π附屬的 樣本框。此外，在用後即棄式紙尿布的情況，依據上述測 量裝置的通常的程序，將試料黏貼在樣本框，並且爲生理 用衛生棉時，將以12 cm xl2 cm被剪下的市售的短褲，例 如綿製的短褲以雙面帶黏貼在樣本框，接著，以雙面帶將 試料黏貼在上述短褲，使試料位於樣本框的中央。 (4) 在散熱器II，將風洞的風速設定在30cm/秒， 將BT-Box的溫度設定在30°C。 (5 )測量爲了將黏貼試料的樣本框的溫度保持在30 °C的所必要的熱量Q d » (6 )在沒有試料的狀態，測量爲了將樣本框的溫度 保持在30°C的必要的熱量Q〇。此外，用後即棄式紙尿布 的時候，僅將樣本框放置在BT-Box的狀態下測量熱量 Qo，而生理用衛生棉的時候，將黏貼短褲的樣本框放置在 BT-Box的狀態下測量熱量Q0。 (7)依下式（1)算出保溫率。 -10- 201233374 保溫率（％ ) = ΐΟΟχ ( Q〇-Qd) /Q〇 式（1 ) 本發明的吸收性物品部中，上述保溫率約45%以下’ 在約43 %以下爲理想，且在約42 %以下則更爲理想。由於 上述保溫率愈高，則穿用者在穿用時感受到熱’因此而容 易發汗，並感受到悶熱。此外’上述保溫率的下限約 0%。藉由讓保溫率接近約〇%的方式，對於熱，能接近沒 有安裝吸收性物品的狀態。 上述保溫率，是例如藉由將吸收性物品的厚度作薄， 尤其是將排泄口抵接域的吸收性物品的厚度作薄的方式可 以降低。藉由將吸收性物品的厚度作薄，應該可使得存在 於吸收性物品內部的保溫性高的空氣的量減少，使得吸收 性物品的保溫率下降。 上述保溫率也會因後述的吸收性物品的密度等而改 變，所以只以吸收性物品的厚度來論述保溫性雖有困難 的，可是爲了達成約45 %以下的保溫率，可將吸收性物品 的厚度，尤其是可將排泄口抵接域的吸收性物品的厚度設 莅例如約7mm以下、約6mm以下、約5mm以下等。此 外’吸收性物品的厚度，尤其是排泄口抵接域的吸收性物 品的厚度在約0 · 1 m m以上爲理想。由於吸收性物品的厚 度小於1 mm時’排泄物的吸收總量容易變得不足夠。 上述吸收性物品的厚度，是例如可使用日本熊谷理機 工業製的TM600-L，以測量件前端直徑：50mm、測量件 下降速度：7.5mm/秒、及測量加重：50gf的條件進行測 -11 - 201233374 量。 上述保溫率，又可藉由將吸收性物品的密度 其是將排泄口抵接域的吸收性物品的密度增高的 降低。將吸收性物品的密度增高，藉此，應該可 物品內部存在的保溫性高的空氣的量減少，並使 品的保溫率下降。 保溫率，是如上述由於也會因吸收性物品的 改變，所以僅以吸收性物品的密度來論述保溫 難，可是，爲了達成約45 %以下的保溫率，可將 品的密度，尤其是將排泄口抵接域的吸收性物品 例如設在約 〇.〇4g/cm3以上、約 0.05g/cm3 I 0.06g/cm3 以上、約 〇.〇7g/cm3 以上等。 此外，本發明的吸收性物品部的密度，尤其 抵接域的收性物品的密度理想是在約0.5g/cm3 且更理想是在約0.3 g/cm3以下。吸收性物品的 時，吸收性物品的剛性會有增加的傾向。 此外，本說明書中，「排泄口抵接域」是指 穿用者的排泄口接觸的區域，在用後即棄式紙尿 大槪與排尿部接觸的區域，而在生理用衛生棉是 與膣口接觸的區域。又，爲了吸收排泄物，在吸 重多的區域存在時，方便上可將該基重多的區域 口抵接域使用。 又’本說明書中，「排泄口抵接域的中心」 收性物品具有翼部時，爲翼部的吸收性物品的長 增高，尤 方式使其 使吸收性 吸收性物 厚度等而 性雖有困 吸收性物 的密度， “上、約 是排泄口 以下，而 密度變高 :大槪與 布是指： 指：大槪 收體有基 作爲排泄 是指；吸 方向的中 -12- 201233374 央，且爲吸收性物品的正交方向的中央，而吸收性物品不 具翼部時，是指吸收體的長方向之具有低窪的部分的中 央，且爲吸收性物品的正交方向的中央。 又，本說明書中，上述密度，是在吸收性物品，以上 述排泄口抵接域的中心爲中心，切出長方向2cm、正交方 向2cm的試料，並藉由測量其質量m ( g )的方式予以算 出。此外，吸收性物品的厚度h ( mm )，可使用由上述 日本熊谷理機工業製的TM6 00-L所測量的値。 密度D ( g/cm3 )，是由以下的式（2)所求出。 D = m/ ( 2x2x0.1 xh ) 式（2) 上述再潤濕率可如以下方式進行測量。 (1 )在吸收性物品的液透過性的頂面薄片上，將在 中央具有約40mmx約10mm的孔的丙嫌酸板，以丙稀酸板 的孔的中心、與吸收性物品的排泄口抵接域的中心大致重 疊的方式放置。 (2)在自動滴定管裝入人工經血，從高度約10〜約 1 5mm朝向丙烯酸板的孔的中心滴下共4g人工經血。滴 下人工經血的速度約95mL/分。 (3 )確認人工經血在吸收性物品被吸收之後，卸下 上述丙烯酸板，從人工經血滴下開始經過1分鐘後，在頂 面薄片上，以排泄口抵接域爲中心，放置1 〇片預先測量 質量（A )的濾紙（日本 ADVANTEC東洋製 Νο·2、尺 201233374 寸：50mmx35mm) 10片，從其上放置5去碼對濾紙施力口 30g/cm2的壓力。 (4 )放置砝碼起經過1分鐘後，從吸收性物品卸下 砝碼及濾紙，測量濾紙的重量（B )。 (5 )依據以下的式（3 )算出再潤濕率。 再潤濕率（質量％) =100χ {質量（B)-質量（A) } /4 式（3) 此外，人工血液，只要黏度大槪在約 22〜約 26mPa · s的範圍內，則並沒有特別的限制，例如，可藉 由對水 lOOOcc混合甘油 80g、CMC的鈉鹽 8g、NaCl l〇g、NaHC03 4g、紅色色素102號8g、紅色色素2號 2g、及黃色色素5號2g的方式調製。 本發明的吸收性物品部中，上述再潤濕率約10質量 %以下，且約8質量％以下爲理想，而約7質量％以下則 更爲理想。上述再潤濕率愈高，吸收性物品吸收排泄物之 後，因坐在椅子上等，對吸收性物品施加壓力之際，會有 容易感覺到黏黏感的傾向。此外，上述再潤濕率的下限約 0質量％。使再潤濕率接近約〇質量％，藉此，本發明的 吸收性物品部在吸收排泄物之後，容易保持乾爽的狀態。 上述再潤濕率，是例如可藉由增加吸收性物品的密 度，尤其是增加吸收性物品的排泄口抵接域的密度的方式 而下降。尤其藉由增加排泄口抵接域的收性物品的密度， 由於吸收性物品內的不織布的纖維、吸收體內部的紙漿彼 -14- 201233374 此的距離會接近，所以因毛細管現象，排泄物容易被吸入 吸收性物品的內部，且容易被保持，應該可使上述再潤濕 率下降。 爲了達成1 〇質量％以下的再潤濕率，排泄口抵接域 的收性物品的密度理想約 0.07g/cm3以上，更理想約 0.08g/cm3以上，且最爲理想約0.09g/cm3以上。 此外，排泄口抵接域的吸收性物品的密度，是如上 述，理想約 0.5g/cm3以下，且更爲理想約 0.3g/cm3以 下。吸收性物品的密度變高時，吸收性物品的剛性會有增 加的傾向。 本發明的吸收性物品，頂面薄片的肌膚抵接面的水分 率在約2 0質量％以下爲理想，在約1 8質量％以下更爲理 想，而且在約1 7質量％以下最爲理想。藉由降低頂面薄 片的肌膚抵接面的水分率，使頂面薄片的肌膚抵接面的極 爲表面的水分率變低，即使吸收排泄物之後，頂面薄片的 肌膚抵接面也可保持乾爽的狀態。此外，上述水分率在約 0.3質量％以上爲理想，而且在約1.0質量％以上最爲理 想。水分率太低時，因氣候會有容易在穿用時產生靜電的 情況。 上述頂面薄片的肌膚抵接面的水分率，可如以下的方 式進行測量。 (1 )準備圖1所示這類的水分量測量裝置，將室溫 調整到20°C，並且將濕度調整到60%RH。此外，關於水 分量測量裝置的詳細容後敘述。 -15- 201233374 (2) 準備水分率已知的複數試料，在該等的試料， 測量施加在一對的電極間的電壓（V )，作成檢量曲線。 (3) 在自動滴定管裝入人工經血，朝向液透過性的 頂面薄片的排泄口抵接域的中心滴下共4g人工經血。 (4 ) 1分過去後’以上述排泄口抵接域的中心爲中 心’在吸收性物品的長方向12mm，正交方向30mm範 圍’測量任意15處的電壓，並依據上述檢量曲線由其平 均値換算成水分率。 圖1所示的水分量測量裝置1，是具備有：靜電容量 式的水分感應器的感應器2 ;試料台3，爲載置由吸收性 物品構成之必須測量的試料的試料台，且在其上具有放置 上述試料用的凸面的試料台；支撐感應器的支撐機構5, 其是將上述感應器之對於上述試料的接觸壓幾乎成爲一定 的方式予以支擦；使試料移動的移動機構6;以及控制移 動機構，藉此一面使感應器對於試料相對移動，一面以感 應器在複數處測量試料的水分量’然後藉此測量試料的水 分量分布的測量機構9。 圖1所示的水分量測量裝置1中，試料台3具有在通 過中心軸線的面切斷正圓柱的方式所形成的半正圓柱型。 再者’圖1所示的水分量測量裝置1中，支撐機構5，是 可依據確碼8的位置調節施加在試料4的負載的天平，可 朝在圖1以B所示的垂直方向（以下，有稱爲「方向Bj 的情況）施加一定的負載》 圖1所不的水分量測量裝置1中，移動機構6，是使 -16- 201233374 試料台3沿著正圓柱的中心軸線的周圍的方向A旋轉， 且可使試料台3朝與正圓柱的中心軸線平行，亦即，在圖 11從面前朝深處的方向往復運動。移動機構6，使試料 台3朝方向a旋轉，且進一步使試料台3從面前朝深處 的方向往復運動，藉此可評價試料的水分量的分布。 圖1所示的水分量測量裝置1中，感應器2是經由支 撐機構5 ’而移動機構6是直接與測量機構9連接。 圖1的水分量測量裝置1中’試料4是被設在試料台 3之上，並且將絕緣薄膜7配置在感應器2與試料4之 間’然後覆蓋試料4。 圖1所示的水分量測量裝置1中，測量試料4的水分 率的分布的程序是如以下所述。首先，準備圖1所示的水 分量測量裝置1。接著，將試料4放置在試料台3的凸 面’在試料4之上放置絕緣薄膜7，然後，將絕緣薄膜7 夾在中間’在試料4之上放置感應器2。接著，操作測量 機構9，控制移動機構6 ’使試料台3朝試料台3的正圓 柱的中心軸線的周圍的A方向旋轉，並且使試料台3從 固前朝深方向移動。隨著此移動，讓感應器2測量複數處 的試料4的水分率。組合該等，藉此可測量試料4的水分 率的分布。 上述感應器雖可隨意採用市售的靜電容量式的水分感 應器，可是該靜電容量式的水分感應器，可具有圖2所示 的這類的剖面形狀。 [塌2所示的感應器2，是具有隔著預先所決定的間隔 -17- 201233374 平行被配置的一對的電極1〇3及10b。—對的電極10a及 1 0 b之間的靜電容量，是經由金屬線被測量。圖2所示的 感應器2，又包含支撐一對的電極l〇a及10b用的電極支 撐部1 1。在圖2所示的感應器2 ’在電極支撐部1 1的測 量側的面，安裝有一對的電極10a及10b。 作爲上述電極支撐部，爲了不對水分率的測量造成影 響，具有與後述的絕緣薄膜同等的介質常數、含水率、及 透水性爲理想。作爲上述電極支撐部的素材的例子，例如 可例舉酚醛樹脂等的商品名所知的酚樹脂。 此外，在圖2所示的感應器2，在一對的電極10a及 1 〇b之間雖沒有任何的存在，可是在上述水分量測量裝置 的其他的實施形態，在一對的電極1 〇a及1 Ob之間，也可 進一步配置有上述電極支撐部。在一對的電極l〇a及l〇b 之間，配置有上述電極支撐部，藉此，可更進一步將電 極、與試料之間的間隔保持在一定。 圖2所示的感應器2，是將絕緣薄膜7夾在之間，與 試料4接觸。在感應器2由於施加有一定的垂直方向的負 載’所以感應器2可一面將一對的電極l〇a及l〇b、與試 料4的距離保持在一定，一面測量靜電容量。 上述水分量測量裝置被配置在上述感應器與上述試料 之間’且包含覆蓋上述試料用的絕緣薄膜的理由，是如以 下所述。 作爲必須測量的試料的吸收性物品，例如用後即棄式 紙尿布的吸收面’排尿後，水分率會有到達接近1 00%的 -18- 201233374 情況。在這樣的高水分率的狀況下，如要使用水分 器，測量水分率時，水分的一部分會附著在感應器’ 是會附著在電極附近，測量結果容易含有誤差。因此 感應器與試料之間，藉由配置與感應器不同體的絕 膜，可防止水分附著在感應器的情況。 此外，上述水分量測量裝置中，感應器這個東西 如圖2所示，在與試料接觸的面，亦可不具有保持作 極的電容器的性質用的絕緣部。又，如公知或市售的 容量式的水分感應器，感應器，在與試料接觸的面也 有保持作爲電極的電容器的性質用的絕緣部。 上述絕緣薄膜在所謂測量水分率的特質上，與真 介電率的比（以下，僅稱爲「介質常數」）在約3 0 爲理想，在約2 0以下更爲理想，在約10以下更是理 並且在約5以下最爲理想。介質常數高時，可能會成 量誤差的原因。 又，上述絕緣薄膜爲了減少測量誤差，膜厚薄且 均一性爲理想。 作爲上述膜厚，在約3 00 // m以下爲理想，在約 // m以下更理想在約1 00 # m以下更爲理想，在約5 以下更是理想，且在約3 0 # m以下最爲理想。 上述均一性，是在任意30點測量後的膜厚的變 數在約20%以下爲理想，在約10%以下更理想，並且 5%以下最爲理想。 此外，變動係數，是以下式（4 ) · 感應 尤其 ，在 緣薄 ，是 爲電 靜電 可具 空的 以下 想， 爲測 具有 200 )从m 動係 在約 -19- 201233374 變動係數（％) =100χ標準偏差/相加平均 所算出的値。 又，上述絕緣薄膜，爲了減少測量誤差， 的含水率爲理想。含水率高的時候，絕緣薄膜 變高，會有測量誤差變大的情況。 上述含水率的基準，是在25 °c在水中浸漬 的含水率小於約3質量％爲理想，小於約1 想，並且小於約〇. 5質量％最爲理想。 再者，上述絕緣薄膜具有低的透水性爲理 水性低的基準，是只要在測量中，感應器，尤

爲了達到本發明的效果，排泄口抵接域的吸收性物品 的厚度約7mm以下，且排泄口抵接域的吸收性物品的密 度約0.07g/cm3以上爲理想，排泄口抵接域的吸收性物品 的厚度約6mm以下，且排泄口抵接域的吸收性物品的密 度約0.07g/cm3以上更理想，排泄口抵接域的吸收性物品 的厚度約5mm以下，且排泄口抵接域的吸收性物品的密 度約0.07g/cm3以上更是理想，而且排泄口抵接域的吸收

The absorbent article portion of the present invention has a heat retention rate of about 45% or less and a rewetting rate of about 10% by mass or less. However, according to the present inventors, the inventor heats the absorbent article. The rate is set to be less than about 45%, and the rewetting rate is set to be less than about 1% by mass, and it is found that it is not easy to be stuffy when worn, and is still dry after absorbing excrement. The above heat retention rate can be measured as follows. (1) Prepare the KES-F7 Precision Rapid Thermal Property Measurement Device Heatsink (THERMOLAB) II, manufactured by Japan Gado Technology Co., Ltd., adjust the room temperature to 20 °C, and adjust the humidity to 60% RH. 201233374 (2) When measuring the heat retention rate of the discarded disposable diaper, center the center of the discharge port abutting area, and cut the direction of the long direction of 12 cm and the direction orthogonal to the long direction (the following is only orthogonal to When the direction of the long direction is called "orthogonal direction", the sample of 12 cm is used. When measuring sanitary napkins, it is generally difficult to ensure that the sample of 1 2 cm X 1 2 cm is difficult. Therefore, cut the sample with a length of 8 cm and an orthogonal direction of 8 cm centering on the center of the discharge port abutment field. 3) Adhere the above sample to the sample frame attached to the radiator with a double-sided tape. Further, in the case of a disposable disposable diaper, according to the usual procedure of the above measuring device, the sample is adhered to the sample frame, and when it is a sanitary napkin, it is commercially available at 12 cm x 12 cm. Shorts, such as cotton shorts, are attached to the sample frame with a double-sided tape, and then the sample is adhered to the shorts with a double-sided tape so that the sample is placed in the center of the sample frame. (4) In the radiator II, set the wind speed of the wind tunnel to 30 cm/sec, and set the temperature of the BT-Box to 30 °C. (5) Measure the heat necessary to maintain the temperature of the sample block of the sample to 30 °C. (6) In the absence of the sample, measure the necessary temperature to keep the temperature of the sample frame at 30 °C. Heat Q〇. In addition, when disposable diapers are used, only the sample frame is placed in the state of BT-Box to measure the heat Qo, and when the sanitary napkin is used, the sample frame of the shorts is placed in the state of the BT-Box. Measure the heat Q0. (7) The heat retention rate is calculated according to the following formula (1). -10-201233374 Insulation rate (%) = ΐΟΟχ (Q〇-Qd) / Q〇 (1) In the absorbent article portion of the present invention, the heat retention rate is about 45% or less, and is preferably about 43% or less. More than about 42% is more desirable. Since the above-mentioned heat retention rate is higher, the wearer feels hot when worn, and thus is prone to sweating and feels stuffy. Further, the lower limit of the above heat retention rate is about 0%. By keeping the heat retention rate close to about 〇%, it is possible to approach the state in which the absorbent article is not attached to the heat. The above heat retention rate can be reduced, for example, by making the thickness of the absorbent article thin, in particular, by thinning the thickness of the absorbent article in the discharge port abutment region. By making the thickness of the absorbent article thin, it is possible to reduce the amount of heat-insulating air present inside the absorbent article, so that the heat retention rate of the absorbent article is lowered. The heat retention rate is also changed by the density of the absorbent article described later, etc. Therefore, it is difficult to discuss the heat retention property only by the thickness of the absorbent article, but the absorbent article can be obtained in order to achieve a heat retention rate of about 45% or less. The thickness of the absorbent article in the excretion port abutment region is, for example, about 7 mm or less, about 6 mm or less, or about 5 mm or less. Further, the thickness of the absorbent article, particularly the thickness of the absorbent article in the discharge port abutment region, is preferably about 0. 1 m m or more. Since the thickness of the absorbent article is less than 1 mm, the total amount of excrement absorbed tends to be insufficient. The thickness of the above-mentioned absorbent article is, for example, TM600-L manufactured by Japan Kumagai Rig Industrial Co., Ltd., with a diameter of the front end of the measuring member: 50 mm, and a descending speed of the measuring member: 7. 5mm / sec, and measurement weight: 50gf conditions to measure -11 - 201233374 amount. The above heat retention rate can be lowered by increasing the density of the absorbent article which is the density of the absorbent article in the discharge port abutment region. By increasing the density of the absorbent article, it is desirable to reduce the amount of air having high heat retention property inside the article and to lower the heat retention rate of the article. The heat retention rate is as described above because of the change of the absorbent article. Therefore, it is difficult to discuss the heat retention only by the density of the absorbent article. However, in order to achieve a heat retention rate of about 45% or less, the density of the product can be made, especially The absorbent article of the drainage port abutment field is set, for example, in about 〇. 〇4g/cm3 or more, about 0. 05g/cm3 I 0. 06g/cm3 or more, about 〇. 〇7g/cm3 or more. Further, the density of the absorbent article portion of the present invention, particularly the density of the absorbent article of the abutting region, is desirably about 0. 5g/cm3 and more preferably about 0. 3 g/cm3 or less. In the case of an absorbent article, the rigidity of the absorbent article tends to increase. In addition, in the present specification, the "excretion port abutment field" refers to an area in which the wearer's excretory opening contacts, and the area where the disposable urine is in contact with the urination portion after use, and in the sanitary napkin is The area where the mouth is in contact. Further, in order to absorb the excrement, when it exists in a region having a large weight, it is convenient to use the region having a large basis weight in the abutment region. In the present specification, "the center of the discharge port abutment field", when the article has a wing portion, the length of the absorbent article of the wing portion is increased, and in particular, the thickness of the absorbent absorbent material is improved. The density of the trapped absorbent material, "upper and lower is below the excretory opening, and the density becomes higher: big sputum and cloth refers to: refers to: the sputum has a base as excretion means; the suction direction of the middle -12- 201233374 In the case of the center of the absorbent article in the direction orthogonal to the direction of the absorbent article, the absorbent article does not have a wing portion, and refers to the center of the portion of the absorbent body having a low waist in the longitudinal direction, and is the center of the absorbent article in the orthogonal direction. In the present specification, the density is obtained by cutting a sample having a length of 2 cm in the longitudinal direction and 2 cm in the orthogonal direction around the center of the discharge port abutting region in the absorbent article, and measuring the mass m ( g ) thereof. In addition, the thickness h (mm) of the absorbent article can be measured by the above-mentioned TM6 00-L manufactured by Japan Kumagai Riki Co., Ltd. The density D (g/cm3) is expressed by the following formula ( 2) Determined. D = m/ ( 2x2x0. 1 xh ) Formula (2) The above rewetting rate can be measured as follows. (1) On a liquid-permeable top sheet of an absorbent article, an acrylic board having a hole of about 40 mm x about 10 mm in the center, a center of a hole of an acrylic plate, and a drain of an absorbent article The center of the abutting domain is placed in a substantially overlapping manner. (2) In the automatic burette, artificial menstrual blood was placed, and a total of 4 g of artificial menstrual blood was dropped from the center of the hole of the acrylic plate from a height of about 10 to about 15 mm. The rate of dropping artificial menstrual blood was about 95 mL/min. (3) After confirming that the artificial menstrual blood is absorbed by the absorbent article, the acrylic plate is removed, and one minute after the artificial menstrual blood dripping, on the top sheet, centering on the discharge port abutting field, and placing one piece of the sheet in advance The filter paper of the measurement quality (A) (Japan ADVANTEC Toyo Co., Ltd. 2, ruler 201233374 inch: 50 mm x 35 mm) was 10 sheets, and a pressure of 30 g/cm 2 of the filter paper application port was placed thereon. (4) After 1 minute from the placement of the weight, remove the weight and filter paper from the absorbent article and measure the weight (B) of the filter paper. (5) The rewet ratio is calculated according to the following formula (3). Rewetting rate (% by mass) = 100 χ {mass (B) - mass (A) } / 4 (3) In addition, artificial blood, as long as the viscosity is greater than about 22 to about 26 mPa · s, then There is no particular limitation. For example, 80 g of glycerin mixed with 100 cc of water, 8 g of sodium salt of CMC, NaCl l〇g, 4 g of NaHC03, 8 g of red pigment 102, 2 g of red pigment 2, and 2 g of yellow pigment 5 Mode modulation. In the absorbent article portion of the present invention, the rewet ratio is preferably about 10% by mass or less, and preferably about 8% by mass or less, and more preferably about 7% by mass or less. The higher the rewetting rate, the more the absorbent article absorbs the excrement, and when the pressure is applied to the absorbent article by sitting on a chair or the like, the adhesive tends to be easily felt. Further, the lower limit of the above rewetting rate is about 0% by mass. The rewetting rate is made close to about 〇% by mass, whereby the absorbent article portion of the present invention is easily maintained in a dry state after absorbing the excrement. The above rewetting rate can be lowered, for example, by increasing the density of the absorbent article, particularly increasing the density of the excretory opening abutment region of the absorbent article. In particular, by increasing the density of the retractable articles in the discharge port abutment area, since the fibers of the non-woven fabric in the absorbent article and the pulp inside the absorbent body are close to each other, the excretion is easy due to the capillary phenomenon. It is sucked into the inside of the absorbent article and is easily held, and the above rewetting rate should be lowered. In order to achieve a rewetting rate of 1% by mass or less, the density of the absorbent article in the discharge port abutment region is preferably about 0. More than 07g/cm3, more ideally about 0. 08g/cm3 or more, and most ideally about 0. 09g/cm3 or more. Further, the density of the absorbent article in the discharge port abutment region is as described above, and is preferably about 0. 5g/cm3 or less, and more preferably about 0. Below 3g/cm3. When the density of the absorbent article is increased, the rigidity of the absorbent article tends to increase. In the absorbent article of the present invention, the moisture content of the skin contact surface of the top sheet is preferably about 20% by mass or less, more preferably about 18% by mass or less, and most preferably about 17% by mass or less. . By lowering the moisture content of the skin contact surface of the top sheet, the moisture content of the surface of the top sheet of the skin contact surface is lowered, and even after the excrement is absorbed, the skin contact surface of the top sheet can be maintained. Dry state. In addition, the above moisture rate is about 0. More than 3 mass% is ideal, and is about 1. 0% by mass or more is most desirable. When the moisture content is too low, there is a case where it is easy to generate static electricity when it is worn due to the weather. The moisture content of the skin contact surface of the top sheet can be measured as follows. (1) A moisture measuring device of the type shown in Fig. 1 was prepared, the room temperature was adjusted to 20 ° C, and the humidity was adjusted to 60% RH. Further, a detailed description of the water content measuring device will be given. -15- 201233374 (2) Prepare a complex sample with a known water content. In these samples, measure the voltage (V) applied between a pair of electrodes to create a calibration curve. (3) In the automatic burette, artificial menstrual blood was placed, and a total of 4 g of artificial menstrual blood was dropped toward the center of the discharge port abutting field of the liquid permeable top sheet. (4) After 1 minute, 'measured at any 15 places in the long direction of the absorbent article 12 mm in the longitudinal direction of the absorbent article, and in the range of 30 mm in the orthogonal direction, based on the above-mentioned calibration curve The average 値 is converted into the moisture rate. The moisture content measuring device 1 shown in Fig. 1 is an inductor 2 including a capacitance type moisture sensor, and the sample stage 3 is a sample stage on which a sample which is required to be measured by an absorbent article is placed, and a sample stage on which the convex surface for the sample is placed, and a support mechanism 5 for supporting the sensor, wherein the contact pressure of the sample to the sample is substantially constant; and the moving mechanism 6 for moving the sample And a measuring mechanism 9 that controls the moving mechanism to thereby measure the moisture content of the sample by measuring the moisture content of the sample at a plurality of points by the sensor while moving the sample relative to the sample. In the moisture content measuring apparatus 1 shown in Fig. 1, the sample stage 3 has a semi-cylindrical shape formed by cutting a right cylinder on a plane passing through a central axis. Further, in the moisture content measuring device 1 shown in Fig. 1, the support mechanism 5 is a balance that can adjust the load applied to the sample 4 in accordance with the position of the confirmation code 8, and can be oriented in the vertical direction shown by B in Fig. 1 ( Hereinafter, there is a certain load applied as the "direction Bj". In the moisture content measuring device 1 shown in Fig. 1, the moving mechanism 6 is such that the -16-201233374 sample table 3 is arranged along the central axis of the right cylinder. The direction A is rotated, and the sample stage 3 can be made to be parallel to the central axis of the right cylinder, that is, reciprocating from the front to the deep direction in Fig. 11. The moving mechanism 6 rotates the sample stage 3 toward the direction a, and Further, the sample stage 3 is reciprocated from the front side in the deep direction, whereby the distribution of the moisture content of the sample can be evaluated. In the moisture content measuring device 1 shown in Fig. 1, the sensor 2 is moved via the support mechanism 5'. 6 is directly connected to the measuring mechanism 9. In the moisture measuring device 1 of Fig. 1, the sample 4 is placed on the sample stage 3, and the insulating film 7 is disposed between the inductor 2 and the sample 4, and then the sample is covered. 4. The moisture measuring device 1 shown in Fig. 1 The procedure for measuring the distribution of the moisture content of the sample 4 is as follows. First, the moisture content measuring device 1 shown in Fig. 1 is prepared. Next, the sample 4 placed on the convex surface of the sample stage 3 is placed on the sample 4 The insulating film 7 is then sandwiched between the insulating films 7 'The inductor 2 is placed on top of the sample 4. Next, the measuring mechanism 9 is operated to control the moving mechanism 6' to bring the sample stage 3 toward the center axis of the positive cylinder of the sample stage 3. The surrounding A direction is rotated, and the sample stage 3 is moved from the solid front to the deep direction. With this movement, the sensor 2 measures the moisture content of the sample 4 at a plurality of points. By combining these, the sample 4 can be measured. Distribution of Moisture Rate Although the above-mentioned inductor can optionally use a commercially available electrostatic capacity type moisture sensor, the electrostatic capacity type moisture sensor can have such a cross-sectional shape as shown in Fig. 2. The sensor 2 shown is a pair of electrodes 1〇3 and 10b arranged in parallel with each other at intervals -17-201233374 determined in advance. The electrostatic capacitance between the electrodes 10a and 10b of the pair is via The metal wire is measured. Figure 2 The inductor 2 further includes an electrode supporting portion 11 for supporting a pair of electrodes 10a and 10b. A pair of electrodes 2' shown in Fig. 2 are mounted on the measuring side of the electrode supporting portion 1 1 In order to prevent the measurement of the water content, the electrode support portion has a dielectric constant, a water content, and a water permeability which are equivalent to the insulating film to be described later. The electrode support portion is an example of the material of the electrode support portion. For example, a phenol resin known by a trade name such as a phenol resin may be mentioned. Further, in the inductor 2 shown in Fig. 2, there is no existence between the pair of electrodes 10a and 1b, but the above In another embodiment of the moisture content measuring device, the electrode supporting portion may be further disposed between the pair of electrodes 1a and 1b. The electrode supporting portion is disposed between the pair of electrodes 10a and 10b, whereby the interval between the electrode and the sample can be kept constant. The inductor 2 shown in Fig. 2 is formed by sandwiching the insulating film 7 and contacting the sample 4. Since the sensor 2 is loaded with a certain load in the vertical direction, the sensor 2 can measure the electrostatic capacitance while keeping the distance between the pair of electrodes 10a and 10b and the sample 4 constant. The reason why the moisture measuring device is disposed between the inductor and the sample and includes an insulating film for covering the sample is as follows. As an absorbent article which must be measured, for example, after the urination of the absorbent surface of the disposable diaper, the moisture rate may reach approximately 10,000% -18-201233374. In such a high moisture rate condition, if a moisture device is to be used, when a moisture content is measured, a part of moisture adheres to the sensor, and it adheres to the vicinity of the electrode, and the measurement result is likely to contain an error. Therefore, it is possible to prevent moisture from adhering to the sensor by disposing a film different from the inductor between the sensor and the sample. Further, in the above-described moisture content measuring device, as shown in Fig. 2, the inductor may not have an insulating portion for retaining the properties of the capacitor on the surface in contact with the sample. Further, as known or commercially available capacity type moisture sensors, the inductor has an insulating portion for retaining the properties of the capacitor as an electrode on the surface in contact with the sample. The insulating film has a ratio of the dielectric constant to the true dielectric constant (hereinafter referred to simply as "dielectric constant"), preferably about 30, more preferably about 20 or less, and about 10 or less. It is more reasonable and is ideal for about 5 or less. When the dielectric constant is high, the cause of the error may be large. Further, in order to reduce the measurement error, the insulating film is preferably thin and uniform in film thickness. The film thickness is preferably about 300 Å / m or less, more preferably about / / m or less, more preferably about 100 Å or less, more preferably about 5 or less, and about 3 0 # m. The following is most ideal. The above uniformity is preferably about 20% or less of the film thickness measured at any 30 points, more preferably about 10% or less, and most preferably 5% or less. In addition, the coefficient of variation is the following formula (4). Inductive, especially in the case of the thin edge, is the following for the electric static electricity. For the test, there is a variation coefficient (%) from the m system at about -19-201233374. =100χ standard deviation/additional average calculated 値. Further, in order to reduce measurement errors, the insulating film preferably has a water content. When the water content is high, the insulating film becomes high and the measurement error becomes large. The above water content is based on the fact that the water content impregnated in water at 25 ° C is preferably less than about 3% by mass, less than about 1 and less than about 〇. 5 mass% is the most ideal. Further, the above-mentioned insulating film has a low water permeability and is a reference for low water repellency, and it is only necessary for the inductor to hit water in the measurement. The electrostatic capacity when the electrode is wet with water. The material of the above-mentioned insulating film is not particularly limited as long as it satisfies the above, and examples thereof include polyamine, epoxy, polyethylene, polypropylene, polyvinylidene chloride, and polychloropentene. The above-mentioned moisture content measuring device has an ideal thickness of about 0% by mass to about 100% by mass, more preferably from about 9% by mass to about 90% by mass, and most preferably from about 5% by mass to about 80%. Sample of moisture content. Further, by using the above-described moisture content measuring device, the moisture of the skin contact surface of the top sheet is excellent in reproducibility, and a commercially available electrostatic capacitance type moisture sensor is used in the middle, and thus has a low formula (4). The dielectric constant is more desirable after 24 hours. If the above-mentioned electrode is not able to measure the performance, the polyamine, ethylene, and polymethylene film can be used. Therefore, it is possible to use about 1% by mass, but it is easy to use, but the insulator is thin, -20-201233374. The moisture content of the skin contact surface of the top sheet was measured. In order to attain the effect of the present invention, the thickness of the absorbent article in the discharge port abutment region is about 7 mm or less, and the density of the absorbent article in the discharge port abutment region is about 0. Preferably, the thickness of the absorbent article of the discharge port abutting region is about 6 mm or less, and the density of the absorbent article of the discharge port abutting region is about 0. More preferably, it is more than 07 g/cm3, and the thickness of the absorbent article in the discharge port abutting area is about 5 mm or less, and the density of the absorbent article in the discharge port abutting area is about 0. More preferably, it is more than 07 g/cm3, and the thickness of the absorbent article in the discharge port abutting area is about 5 mm or less, and the density of the absorbent article in the discharge port abutting area is about 〇. 〇75g/cm3 or more is most desirable. Further, as described above, the thickness of the absorbent article in the discharge port abutment region is about 0. More than 1mm is ideal. Since the above thickness is less than 1 mm, the total amount of excrement absorbed is likely to be insufficient. Moreover, the density of the absorbent article in the discharge port abutment area is preferably about 〇. 5g/cm3 or less, and most preferably about 0. 3g/cm3 or less. When the density is increased, the rigidity of the absorbent article tends to increase. The basis weight of the excretory opening abutment region of the absorbent body used in the absorbent article of the present invention is that the absorbent article of the present invention has a heat retention rate of about 45% or less and a regreasing amount of about 1% by mass or less. The range of the moisture ratio is not particularly limited 'but may be, for example, about 250 to about 500 g/m 2 , about 25 0 to about 400 g/m 2 , about 250 to about 3 50 g/m 2 , and the like. When the basis weight of the absorbent body in the excretion opening abutment region is small, the rewetting rate tends to be high, and when the basis weight of the absorbent body in the excretion opening abutting region is increased, the wearing feeling is hardened. Propensity. 21 · 201233374 The basis weight of the region other than the row of the absorbent body used in the absorbent article of the present invention is less than the basis weight of the discharge port abutting domain, as may be about 300 g/m 2 or less and about 200 g/m 2 or less. . The base rewetting rate of the absorbent body in the region other than the excretion opening abutment tends to decrease, but the thickness tends to increase, and when the thickness is reduced by pressing, the wear tends to be hard. In the absorbent body used in the absorbent article of the present invention, it is preferable that a plurality of pressure absorbers are formed by pressing a part of the absorbent body. The heat retention rate and the rewetting rate of the absorbent article of the present invention are increased by compressing the density of the entire body of the absorbent body, that is, the absorbent article of the present invention. Fig. 3 is a view showing the implementation of the absorbent body used in the present invention. In the absorbent body 21 which is not shown in Fig. 3, the direction toward the left side is the front of the wearer, and the direction toward the right side is the direction when the wearer is in the square. In the absorbent body 21 of Fig. 3, a plurality of pressing sounds are comprehensive, and in the absorbent body 21, the drain opening abutment field 22 is shown. Although the shape, the area, the number, and the like of the press portion are not particularly as shown in Fig. 3, the press portion having a small area is almost uniformly dispersed so that the press portion can be almost uniformly dispersed, and at least the area ratio of the excrement at least the press portion can be reduced. Further, in the absorbent article used in the present invention, it is also preferable that the absorbent article is easily detached from the shape of the wearer's body in the absorbent body, for example, 1 00 g/m 2 . When there is a lot of change, there will be a change in the heat retention rate, and there will be a thickness in the direction of the press portion, increasing the absorbance, and reducing the time of the polymorphic one becomes the wearer's post. 23 exists in the dotted line. Table limits are ideal. Because of the absorption of the entire thin film, several press sections have a certain degree of -22-201233374 deformation configuration. For example, in the entire direction of the absorbent body, a slightly rectangular press portion is disposed at a constant interval in the orthogonal direction of the absorbent body so that the longitudinal direction of the press portion coincides with the direction orthogonal to the absorbent body, thereby making the absorbent article It is easy to deform along the shape of the wearer's buttocks. Further, as shown in Fig. 3, in the region of the absorbent body which is in contact with the groin portion of the wearer, the longitudinal direction of the press portion 23 and the longitudinal direction of the absorbent body 21 are in the longitudinal direction of the absorbent body. The press portion 23 is disposed at a predetermined interval, whereby the absorbent article can be easily followed when the wearer closes the leg. Further, as shown in FIG. 3, in the excretory opening abutment region 22 of the absorbent body 2, by reducing the number of the press portions 23, the excretory opening abutment region 22 is easily expanded, and a larger amount can be easily absorbed. Excreta. In addition, in order to easily absorb a larger amount of excrement, the area of each of the press sections in the discharge port abutment domain can also be reduced. In the slightly rectangular press portion of the above absorbent body, the long diameter is about 1. 0~about 3. 0mm is ideal and is about 1. 5~about 2. 5mm is more ideal, and the short diameter is about 0. 2~about 2mm is ideal, and is about 0. 3~about 1. 0mm is more ideal. When the shape of the press portion is small, the press tends to be insufficient. However, when the shape is increased, the rigidity of the absorbent article of the present invention becomes high, and the wearing feeling tends to be broken. In the above absorbent body, the area ratio of the press portion to the press surface of the absorbent body is preferably from about 1 to about 10%, and more preferably from about 2 to about 5%. When the area ratio is small, the press is insufficient, and as a result, the thickness of the absorbent body and the absorbent article is increased, and the density of the absorbent article tends to decrease from -23 to 201233374, and when the area ratio is high, the absorbability is high. The just absorption of the article tends to decrease. Further, the above area ratio is the area of the pressurizing body which can be divided by the area of the press section of the absorber. Further, it is preferable that the press portion is provided with a saw-arc jagged type, a 60° zigzag type, or the like in the absorber. Such a thickness, density, and the like are uneven. The above-mentioned press section is preferably an interval of 10 mm apart from the adjacent press sections, and is preferably about 2 to about 6 mm. In this case, the thickness, density, and the like of the absorbent body are not easily caused, and the structure of the absorbent body is not particularly limited. For example, absorbent paper, such as a pulp or an absorbent material, such as an absorbent core formed of SAP, is coated with a thin tissue such as a smear. In the liquid permeability of the absorbent article of the present invention, the absorbent article of the present invention has a rewetting ratio of not less than 45% by weight of the absorbent article, and there is no particular limitation on the hot air. Not woven. Further, the above-mentioned liquid-permeable top sheet has a plurality of convex portions and a plurality of concave portions which are alternately extended in the direction of absorption in the direction orthogonal to the absorbent article, and have a concave shape (hereinafter referred to as "having only" Fig. 4 is a view showing an example of a non-woven fabric having irregularities. The shape is increased, and the number of the remaining portions is multiplied by the area. For example, it is easy to absorb the body sentence from 1 mm to about the interval. The liquid permeable and the desired formation are used. The top sheet, the temperature ratio, and 10, for example, when the long non-woven fabric of the effective article of the present invention is used, is shown in Fig. 4. • 24-201233374 has unevenness The nonwoven fabric 24' is a plurality of concave portions 26 having a plurality of convex portions 25 extending in the longitudinal direction of the absorbent article on the orthogonal side of the absorbent article (only one is shown in Fig. 4). The above-mentioned non-woven fabric having irregularities can be produced by a method known in the art, for example, according to the method described in JP-A-2008-25081, JP-A-2008-25082, and the like. For example, as shown in FIG. 5, the web 3 is placed on a roll having a mesh member 29, and the flow from the fluid nozzle 31 to the web 30' is thereby formed to have irregularities. Non-woven fabric 24 The uneven nonwoven fabric 24 is divided in a direction immediately below the nozzle in which the fluid is ejected in the orthogonal direction CD orthogonal to the transport direction MD, and the recessed portion in the transport direction MD is distinguished. Further, a convex portion along the transport direction MD is formed in a region between the nozzles. The fluid is, for example, steam, and for example, a discharge amount of about 5 to (nL/m2) can be used. Further, the concave portion of the non-woven fabric is formed immediately below the fluid from which the fluid is blown, and is formed adjacent to the concave portion. Therefore, the height of the fluid nozzle can be formed to form a desired height and pitch of the convex portion. The fiber having the uneven fabric formed of the above-mentioned fiber web and the above-mentioned fiber web is not particularly limited, and examples thereof include polyethylene fiber and ethylene glycol diester fiber, and combinations thereof. The basis weight of the above-mentioned fiber web and the uneven nonwoven fabric formed of the above-mentioned fiber web are preferably from 10 to 50 g/m 2 , and more preferably from 20 to 50 g/m 2 . When the above-mentioned basis weight is small, the top surface is alternately touched, and the complex method, the specific opening, and the like are touched. The fibers are formed along the fibers and are convex at about 15 nozzles. The uneven poly(p-phenylene) has a concave shape and is damaged when the sheet is used in -25-201233374. When the basis weight is increased, the thickness of the top sheet becomes thick, and the heat retention rate of the absorbent article tends to increase. In the above non-woven fabric having irregularities, the height of the convex portion is about 0. 5~about 2. 0mm is ideal and is about 0. 7~about 1. 5mm is more ideal. The height of the recess is about 0. 3~about 0. 7mm is ideal, and is about 0. 5~about 0. 6mm is more ideal. In the non-woven fabric having irregularities, the pitch of the concavities and convexities is preferably from about 2 to about 6 mm, and preferably from about 3 to about 5 mm. Further, in the present specification, the height of the convex portion means a height from the bottom of the non-woven fabric to the top of the convex portion as indicated by hi in FIG. 4, and the height of the concave portion means: as shown by h2 in FIG. The height from the bottom of the nonwoven to the bottom of the recess. Further, the pitch of the concavities and convexities means a distance from a certain convex portion to an adjacent convex portion as indicated by P in Fig. 4 . In the absorbent article of the present invention, the liquid-permeable top sheet has a plurality of convex portions extending in the longitudinal direction of the absorbent article alternately in the direction perpendicular to the longitudinal direction on the muscle 0 abutting surface, and a plurality of convex portions It is more preferable that a part of the plurality of concave portions has a non-woven fabric (hereinafter referred to as "non-woven fabric having irregularities and holes" having irregularities and holes in the non-woven non-woven holes. The liquid-permeable top sheet has a hole 'to easily suck the excrement from the top sheet into the inside of the absorber. Fig. 6 is a schematic view showing a first embodiment of a nonwoven fabric having irregularities and holes. The non-woven fabric 32 having irregularities and holes shown in Fig. 6 is a hole 33 having a non-woven fabric in the concave portion 26. The diameter of the above hole 'in the longitudinal direction of the absorbent article is about 2. 0~about -26- 201233374 2. 5mm is ideal, and the diameter in the orthogonal direction of the absorbent article is about 0. 5~about 1. 5mm is ideal, and the spacing of the adjacent holes of the same recess is about 2. 0 ~ about 2. 5mm is ideal.
