As this fiber assembly, a filament assembly obtained by opening, as necessary, synthetic fiber tows (fiber bundles) such as cellulose acetate as well as short fibers such as cotton-like pulp and synthetic fibers Can also be used. The fiber basis weight can be set to, for example, about 100 to 300 g / m 2 when cotton-like pulp or short fibers are stacked, and in the case of a filament aggregate, for example, about 30 to 120 g / m 2. Can do. The fineness in the case of a synthetic fiber is 1-16 dtex, for example, Preferably it is 1-10 dtex, More preferably, it is 1-5 dtex.

Further, a crimped fiber that is uniformly crimped is often used. It is preferable to disperse and hold superabsorbent polymer particles in the absorber 56.
<明細書中の用語の説明>
明細書中で以下の用語が使用される場合、明細書中に特に記載が無い限り、以下の意味を有するものである。
・「前後(縦)方向」とは腹側(前側)と背側(後側)を結ぶ方向を意味し、「幅方向」とは前後方向と直交する方向(左右方向)を意味する。
・「伸長率」は、自然長を100%としたときの値を意味する。
・「目付け」は次のようにして測定されるものである。試料又は試験片を予備乾燥した後、標準状態(試験場所は、温度20±5℃、相対湿度65%以下)の試験室又は装置内に放置し、恒量になった状態にする。予備乾燥は、試料又は試験片を相対湿度10〜25%、温度50℃を超えない環境で恒量にすることをいう。なお、公定水分率が0.0%の繊維については、予備乾燥を行わなくてもよい。恒量になった状態の試験片から米坪板(200mm×250mm、±2mm)を使用し、200mm×250mm(±2mm)の寸法の試料を切り取る。試料の重量を測定し、20倍して1平米あたりの重さを算出し、目付けとする。
・「厚み」は、自動厚み測定器(KES−G5 ハンディ圧縮計測プログラム)を用い、荷重:0.098N/cm2、及び加圧面積:2cm2の条件下で自動測定する。
・吸水量は、JIS K7223−1996「高吸水性樹脂の吸水量試験方法」によって測定する。
・吸水速度は、2gの高吸収性ポリマー及び50gの生理食塩水を使用して、JIS K7224‐1996「高吸水性樹脂の吸水速度試験法」を行ったときの「終点までの時間」とする。
・試験や測定における環境条件についての記載が無い場合、その試験や測定は、標準状態(試験場所は、温度20±5℃、相対湿度65%以下)の試験室又は装置内で行うものとする。
<Explanation of terms in the specification>
When the following terms are used in the specification, they have the following meanings unless otherwise specified in the specification.
The “front / rear (vertical) direction” means a direction connecting the ventral side (front side) and the back side (rear side), and the “width direction” means a direction (left / right direction) orthogonal to the front / rear direction.
“Elongation rate” means a value when the natural length is 100%.
・ "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). Measure the weight of the sample, multiply it by 20, calculate the weight per square meter, and use it as the basis weight.
-"Thickness" is automatically measured using an automatic thickness measuring instrument (KES-G5 handy compression measurement program) under the conditions of load: 0.098 N / cm 2 and pressure area: 2 cm 2 .
-The amount of water absorption is measured according to JIS K7223-1996 "Test method for water absorption of superabsorbent resin".
・ The water absorption rate is the “time to end point” when JIS K7224-1996 “Test method for water absorption rate of superabsorbent resin” is performed using 2 g of superabsorbent polymer and 50 g of physiological saline. .
・ If there is no description about the environmental conditions in the test and measurement, the test and measurement shall be performed in a test room or equipment in the standard condition (test location is temperature 20 ± 5 ℃, relative humidity 65% or less). .
