- the holding force of the fifth peel test on the back surface is higher than the holding force of the first peel test. This is because by repeating the peel test, the thickness of the female member recovered and the engagement force increased.
- Comparative Example 1 had good peel strength and fuzzing, but the holding power test and the engagement stickiness test were poor. In the comparative example 2, it peeled and destroyed in the 5th peeling test of a 135 degree peel test. Therefore, Comparative Examples 1 and 2 do not have a level as a good female member. Here, as for the state of destruction, the material itself is disconnected in the Z direction (thickness direction), and the material is stuck to the male member in layers.
- FIG. 15 is a characteristic diagram of engagement tenacity in the peel test
- curve E represents engagement tenacity on the surface of Example 1
- curve F represents engagement tenacity on the back surface of Example 1.
- Curve G shows the engagement stickiness of the surface of Comparative Example 1
- curve H shows the engagement stickiness of the surface of Comparative Example 2. In Example 1, both the front surface and the back surface have large engagement stickiness.
- the female member of the hook-and-loop fastener according to the present invention, when the fiber dense portion having a high basis weight of the fibrous material is pulled in the thickness direction, the elastic deformation in which the height is increased while the width is reduced. As a result, the engagement with the male member becomes sticky and the engagement is improved. Therefore, it is useful in absorbent articles such as disposable diapers, sanitary napkins and panty liners.

Abstract
Description
表1の配合比率の繊維を図8及び図9に示す製造装置に供給して面ファスナーの雌部材(不織布)を製造した。この製造は、孔径1.0mm、ピッチ50mmのノズル13aを4列配置し、ホットエアージェットノズル13から温度150℃、風量0.12m3/分/m2のホットエアージェットを吹き付け、その後、熱風加熱炉15内で温度150℃、風量15m3/分/m2の熱風20を約10秒間吹き付けることにより行った。これにより、目付け35g/m2、畝部4のピッチが5mm、溝部5の幅が1.3mmの表面を有した実施例1のエアースルー不織布を得た。この場合、溝部5には、MD方向に沿って5mmピッチの開口部6が形成されている。
実施例1及び比較例1、2に対して、同じ構造の雄部材をMD方向から係合させて剥離強度、毛羽立ち、保持力、係合粘りについて評価した。結果を表2に示す。厚さに関しては表1に示す。以下に評価方法を説明する。
10cm角のサンプルを厚さ計(商品名「PEACOK DIAL THICKNESS GAUGE No.CI1352」)により3g/cm2の荷重で測定した。
雌部材となっている不織布を3~5cm×5cmにカットして試験片とし、この試験片を5cm×8cmのスパンボンド不織布(20~30g/cm2)に両面粘着テープで剥がれないように貼り付けて雌部材サンプル53とした。一方、2cm×3cmの雄部材を12cm×3cmのスパンボンド不織布(20~30g/cm2)に両面粘着テープで剥がれないように貼り付けて雄部材サンプル56とした。
上側チャック-サンプル間=50mm(垂直方向)
[保持力試験]
図13に示す保持力試験に用いる雌部材サンプル59は、5cm×5cmの雌部材61を10cm×10cmのスパンボンド不織布(20~30g/cm2)に両面粘着テープで剥がれないように貼り付けて作成する。また、保持力試験に用いる雄部材サンプルは、2cm×4cmの雄部材54を4cm×8cmのスパンボンド不織布(20~30g/cm2)に両面粘着テープで剥がれないように貼り付けて作成する。
図14は係合粘り試験に用いる雌部材サンプルは、2cm×4cmの雌部材を3cm×5cmのスパンボンド不織布(20~30g/cm2)に両面粘着テープで剥がれないように貼り付けて作成する。係合粘り試験に用いる雄部材は、1.5cm×3cmの大きさとし、その裏面に両面粘着テープを貼り付ける。この雄部材を雌部材サンプルの上に重ねてその上から700gローラーを300mm/minの速度で1往復して雄部材と雌部材とを係合させる。
