Abstract
An absorbent article comprising an absorbent core having a longitudinally extending channel-forming area and a wetness indicator. The core wrap comprises a top side and a bottom side, which are attached to each other through areas substantially free of absorbent material, so that when the absorbent material swells upon absorption of a liquid a channel is formed along the area substantially free of absorbent material.
Claims18
An absorbent article comprising:
- a) a topsheet;
- b) a backsheet;
- c) an absorbent core disposed between the topsheet and backsheet, the absorbent core comprising a core wrap enclosing an absorbent material comprising wood pulp and superabsorbent polymer particles;
- d) a disappearing wetness indicator;
- and
- e) a longitudinally extending channel-forming area that is substantially free of the wood pulp and superabsorbent polymer particles and through which a top side of the core wrap is attached to a bottom side of the core wrap;
- f) whereupon absorption of a liquid by the absorbent article, both:
- i.) a channel is formed along the channel-forming area, the channel becoming visible from an exterior of the article;
- and
- ii.) the disappearing wetness indicator becoming invisible or less discernible when looking at the backsheet.

- ii.) regions of the absorbent article in a crotch region that are distal to the channel bulge outward when looking at the backsheet in comparison to regions of the absorbent article in the crotch region that are close to or in contact with the channel;
- and
- iii.) the wetness indicator changes appearance when looking at the backsheet.
