Abstract
A stretchable absorbent article comprises a stretchable backsheet and an absorbent core that is at least partially enveloped by a stretchable core wrap. The absorbent core has a quantity of superabsorbent materials contained within a matrix of polymer fibers. The stretchable core wrap has a mean flow pore diameter of less than about 41 microns. The stretchable article may additionally have a stretchable bodyside liner as well as other stretchable components. The stretchable absorbent article can provide greater performance as well as greater comfort and confidence among the user.
Claims34
An absorbent article comprising:
- a stretchable backsheet;
- and
- an absorbent composite in facing relationship with said stretchable backsheet comprising an absorbent core and a stretchable core wrap that at least partially envelopes said absorbent core;
- wherein said absorbent core includes a quantity of superabsorbent materials;
- and
- wherein said core wrap has a mean flow pore diameter less than about 41 microns.
An absorbent article comprising:
- a stretchable backsheet;
- a stretchable bodyside liner
- an absorbent composite disposed between said stretchable backsheet and said stretchable bodyside liner comprising an elastically extensible absorbent core and an elastically extensible core wrap having a mean flow pore diameter less than about 35 microns;
- wherein said elastically extensible absorbent core includes at least 60% superabsorbent materials;
- wherein said elastically extensible core wrap comprises fibers having a fiber diameter of 20 microns or less;
- and
- wherein said elastically extensible core wrap at least partially envelopes said elastically extensible absorbent core.
An absorbent article comprising:
- A stretchable backsheet;
- A stretchable bodyside liner;
- An absorbent composite disposed between said stretchable backsheet and said stretchable bodyside liner comprising a stretchable absorbent core and a stretchable absorbent core wrap;
- wherein said stretchable absorbent core comprises at least about 60% of a superabsorbent material having a surface cross-linking and a substantially non-covalently bonded surface coating with a partially hydrolysable cationic polymer;
- and
- wherein said stretchable core wrap has a mean flow pore diameter less than about 35 microns.
