Abstract
Provided is a water-decomposable absorbent article including a water-decomposable back sheet, a water-decomposable absorbent layer, and a surface member covering the absorbent layer. The surface member has a plurality of water-retentive water-decomposable sheets laminated and bonded to each other by integration means for permitting to dissociate the water-decomposable sheets from each other when wetted.
Claims15
A water-decomposable absorbent article comprising:
- a water-decomposable back sheet;
- a water-decomposable absorbent layer;
- and
- a surface member covering the absorbent layer;
- the surface member comprising a plurality of water-retentive water-decomposable sheets laminated and bonded to each other by integration means for permitting the water-decomposable sheets to dissociate from each other when wet, and having a tensile strength of at least 1000 g/25 mm when dry.
A water-decomposable absorbent article comprising:
- a water-decomposable back sheet;
- a water-decomposable absorbent layer;
- and
- a surface member covering the absorbent layer;
- the surface member comprising a plurality of water-retentive water-decomposable sheets laminated and bonded to each other by integration means for permitting the water-decomposable sheets to dissociate from each other when wet, and having a tensile strength of at least 200 g/25 mm when wet.
A water-decomposable absorbent article comprising:
- a water-decomposable back sheet;
- a water-decomposable absorbent layer;
- and
- a surface member covering the absorbent layer;
- said surface member comprising a plurality of water-retentive water-decomposable sheets laminated and bonded to each other by needling to provide through-holes, so that fibers constituting each water-decomposable sheet are entangled around said through-holes.
A water-decomposable absorbent article comprising:
- a water-decomposable back sheet;
- a water-decomposable absorbent layer;
- and
- a surface member covering the absorbent layer;
- said surface member comprising a plurality of water-retentive water-decomposable sheets laminated and bonded to each other by embossing said water-decomposable sheets.
A water-decomposable absorbent article comprising:
- a water-decomposable back sheet;
- a water-decomposable absorbent layer;
- and
- a surface member covering the absorbent layer;
- said surface member comprising a plurality of water-retentive water-decomposable sheets laminated and bonded to each other by bonding the water-decomposable sheets to each other through hydrogen bonding.
