Abstract
The present invention provides a liquid distribution layer for absorbent articles which exhibits directional liquid distribution properties and has desirable physical integrity. The liquid distribution layer is a nonwoven web of substantially continuous microfibers that has its fibers substantially aligned along one planar dimension of the web, wherein the fibers are hydrophilically modified or hydrophilic. Additionally, the liquid distribution layer may have an increasing fiber alignment gradient as well as a decreasing fiber thickness gradient in the direction of the web thickness. Further provided are suitable processes for producing the liquid distribution layer.
