Abstract
Description
秤量の均一性を測定するための方法
評価のため、1つの同じ消費者パッケージから5つの隣接するおむつを取り出す、または5つの連続して製造されたおむつを製造から取り出す。
(サンプル重量(g))/(サンプル面積(0.001m2))
このテストは、吸収性アセンブリの前部および後部領域における保持容量の均一性を評価し、超吸収性ポリマーの分布を示す。この目的のため、秤量均一性テスト(上述)において用いられたのと同じ60サンプルを用いる。
g/g吸収性=(最終サンプル重量−初期サンプル重量)/初期サンプル重量
g/10cm2吸収性=最終サンプル重量−初期サンプル重量
吸収性アセンブリの保持容量は、CRCテスト(遠心分離保持容量)の原理に沿って容易に評価することができる。この方法は業界においてよく知られており、フルネームのStandard Procedure、NWSP 241.0.R2(15)、Polyacrylate Superabsorbent Powders − Determination of the Fluid Retention Capacity in Saline Solution by Gravimetric Measurement Following Centrifugationの下でEDANAまたはINDAから入手可能である。しかしながら、このテストは小さなサンプル用に設計されており、以下に説明するように、吸収性アセンブリ全体を評価するにはいくつかの変更が必要である。
NWSP 070.9.R1(15)に記載されている方法に従って、2つの異なる大人用オープンおむつについて、2つの液体捕捉特性、捕捉速度(ROA)およびリウェットを評価した。
