Abstract
An absorbent structure comprising a fibrous web of cellulosic material, a first complex forming material present within said web and a second complex forming material present within said web. When wetted, the first and second complex forming materials form a complex thereby providing the fibrous web of cellulosic material with improved integrity.
Claims29
An absorbent structure, said absorbent structure comprising:
- a) an absorbent fibrous web of material;
- b) a first complex forming material present in said web;
- and
- c) a second complex forming material present in said web;
- wherein, at least one of said first or second complex forming materials is water-soluble and further wherein in the presence of water, said first and second complex forming materials form a complex.
2 more elements
An absorbent structure, said absorbent structure possessing improved dry and wet integrity and comprising:
- a) a fibrous web of cellulosic fibers;
- b) a first solid water-soluble complex forming material present in said web;
- c) a second solid water-soluble complex forming material present in said web;
- wherein at least one of said first or second solid water-soluble complex forming materials is a thermoplastic polymer and has a Vicat softening point within the range of from about 30.degree. C. to about 200.degree. C., said at least one of said first or second solid water-soluble complex forming material binding fibers of the fibrous web together when dry, thereby improving the dry integrity of said web, wherein, when wetted, said first and second water-soluble complex forming materials form a complex which complex improves the wet integrity of the web.

A diaper, said diaper comprising:
- a) a water-pervious body-side liner;
- b) a water-impervious backing sheet;
- and
- c) an absorbent structure sandwiched between said body-side liner and said backing sheet, said absorbent structure comprising:
- 1) an absorbent fibrous web of cellulosic material:
- 2) a first complex forming material present in said web;
- and
- 3) a second complex forming material present in said web:
- wherein, at least one of said first or second complex forming materials is water-soluble and further wherein in the presence of water, said first and second complex forming materials form a complex.
