Description
該吸収部は、該基盤シートを伸縮させても形状が変化しないような態様で、固定点を介して該基盤シートに固定されており、
該固定点間において伸縮性を発現している伸縮性吸収体を提供するものである。
保持量(g/g)=(M1−M0)/(M0)
伸縮率=回復伸び/最大伸び長さ(=50mm) (1)
ここで、回復伸びは、最大伸び長さ(=50mm)からチャックを下降させて、初めて荷重ゼロを記録したときの、最大伸び長さからのチャック移動距離で定義される。なお、測定片が前述の大きさに満たない場合、下記方法で測定する。
<試験片> シートのチャック間方向の長さをLmm、把持部分の長さをSmm、幅をCmmとすると、長さの比;L:C=3:5になるように、試験片(L+2S)mm×Cmmの大きさに裁断し測定片を採取する。
<試験> 引張圧縮試験機に、チャック間距離Lで試験片をセットし、100×(L/30)mm/分、測定片が初期試料長の50%伸張するまで上昇。その後チャックの移動方向を逆転させ、チャックを100×(L/30)mm/分の速度で下降させ、初期試料長の位置まで戻す。下記式(2)で計算する。
