Absorbent article with high absorbent material content
An absorbent article includes a longitudinal axis extending in a longitudinal direction of the article, a liquid permeable topsheet, a liquid impermeable backsheet, and an absorbent core disposed between the topsheet and backsheet. The absorbent core includes a combination of superabsorbent polymer and cellulose fibers. The article further includes an acquisition-distribution layer; and at least one channel positioned within a layer located between the topsheet and the backsheet, the at least one channel being substantially free of fibers and superabsorbent polymer. An indentation occurs in at least one of the topsheet and the backsheet that correspond to the at least one channels when the article is loaded with fluid.
