Abstract
An absorbent core for use in an absorbent article such as a diaper, training pant, feminine hygiene product, or an incontinence product includes a stabilized first absorbent layer and a second absorbent layer that contains a superabsorbent and absorbent fibers treated with a non-fugitive densification agent.
Claims44
An absorbent core for use in an absorbent article comprising:
- a. a stabilized first absorbent layer;
- and,
- b. a second absorbent layer adjacent the first absorbent layer and including (i) absorbent fibers treated with a non-fugitive densification agent and (ii) a superabsorbent material.
An absorbent core for use in an absorbent article comprising:
- a. a stabilized first air formed absorbent layer including absorbent fibers such that the first absorbent layer in a dry state has a tensile strength of at least about 6 N/50 mm and in a wet state has a tensile strength of at least about 2 N/50 mm;
- and,
- b. a second absorbent layer adjacent the first absorbent layer and including (i) absorbent fibers treated with a non-fugitive densification agent and (ii) a superabsorbent material wherein the non-fugitive densification agent forms hydrogen bonds and is selected from the group consisting of polymeric densification agents, non-polymeric densification agents, and mixtures thereof.
An absorbent article comprising:
- a. a liner;
- b. a baffle;
- c. a stabilized first absorbent layer;
- and,
- d. a second absorbent layer adjacent the first absorbent layer and including a superabsorbent material and absorbent fibers treated with a non-fugitive densification agent.
