Abstract

The present invention provides absorbent articles, especially sanitary napkins, containing a fluid transport layer. In-use, the transport layer directs menses to a storage layer, thereby minimizing product failure and staining of undergarments. The transport layer can protrude into, or through, a topsheet to provide very aggressive transport of vaginal discharges. Preferably, the transport layer is a layer of fibers having external capillary channels.
