Abstract
A feminine care absorbent article having fluid barrier and decolorizing structures is described. Such structures can prevent the spread of menses fluid towards the edges of the article and can also decolorize stains so that the stains are less noticeable. The article includes a liquid permeable topsheet having a central layer positioned adjacent opposing side layers. The side layers can include a separating region that at least partially separates a decolorizing agent carrier material treated with a decolorizing agent from an absorbent core. At least one of the side layers can also include at least one fluid barrier region that can prevent or slow the spread of fluids from the center of the article to the edges. The combination of the separating and fluid barrier regions can allow the decolorizing agent to sufficiently decolorize a fluid insult that may have spread to the lateral edges of the article.
