대표청구항 ▼

[ We claim:] [1.] An absorbent body for use in an absorbent article to be worn by a wearer, comprising:an air containing voluminous first layer of fluff which lies nearest the wearer in use,a first superabsorbent mixed in said first layer and which has a degree of cross-linking providing a gel strength high enough so as to swell under normal use pressure in said article without changing shape so that the fluff of the first layer, which collapses when absorbing liquid, will be loosened and therewith again form an air-containing, voluminous layer of fluff, anda second layer containing a second superabsorbent wherein said second superabsorbent has a higher liquid absorbency, when in use by a wearer, than the first superabsorbent and thus absorbs more liquid than the first superabsorbent.
