Abstract:
An absorbent article comprising:an absorbent core containing a highly absorbent resin; and a polyvalent metal compound which is present in the absorbent article separately and undissolved in the highly absorbent resin, and prevents melting, solidification and deposition of the highly absorbent resin on the wall of an incinerator during incineration of the absorbent article; wherein the separation of the polyvalent metal compound from the highly absorbent resin is established by one of: (a) grinding and dispersing the polyvalent metal compound while in solid form, along with the highly absorbent resin in the absorbent core and arranging the polyvalent metal compound proximally to the highly absorbent resin; (b) adding the polyvalent metal compound to an element of the absorbent article for containment therein to prevent the polyvalent metal compound from contacting liquid which is introduced into the absorbent article; and (c) covering or wrapping the polyvalent metal compound with a liquid-impermeable material such that the polyvalent metal compound is prevented from contacting liquid which is introduced into the absorbent article.
