Disposable Absorbent Article with Unitary Topsheet and Unitary Absorbent Article

摘要

The present invention relates to disposable absorbent articles such as sanitary napkins, panty liners, baby diapers, adult incontinence articles and sweat pads. According to the present invention the absorbent article in the region designated for liquid deposition on its wearer facing surface has a single layer topsheet onto which liquid to be absorbed is provided during use of the article. The absorbent article includes a backsheet forming the liquid barrier surface and a unitary absorbent core between the topsheet and the backsheet. Importantly the unitary core provides improved liquid handling to the absorbent article and increases the masking, i.e. ability to hide stains due to absorbed liquid, of the article. This is particularly beneficial in the context of articles for absorption of liquids with high color intensity, such as menstrual liquid or urine of older adults.
