ABSTRACT:
Absorbent article comprising an optional liquid permeable topsheet, an optional, sometimes liquid impermeable, backsheet, an absorbent core disposed between the topsheet and backsheet, if any, and at least one liquid management member which comprises a film having at least one microstructure-bearing hydrophilic surface that promotes rapid directional spreading of liquids, the liquid management member and core being in contact. Also, liquid management members which comprise a film having at least one microstructure-bearing hydrophilic surface that promotes directional spreading of liquids. The surface has a plurality of V-shaped grooves having an angular width of Alpha, Alpha being between about 10.degree. and about 120.degree.. The hydrophilic surface has a contact angle with water of Theta, Theta being equal to or less than (90.degree.-Alpha/2).
