Abstract
A permeable, liquid flow control material composed of: 1) a permeable sheet having a plurality of individual exposed surfaces, at least a portion of which have a surface energy of less than about 45 dynes/cm; and 2) amphiphilic proteins adsorbed onto at least some individual exposed surfaces to define a gradient distribution of amphiphilic protein coating along at least one dimension of the permeable sheet so that the adsorbed amphiphilic protein coating provides controlled wettability along at least one dimension of the liquid flow control material. Desirably, the liquid flow control material is substantially free of fugitive amphiphilic proteins. The material may be used as a permeable, bodyside cover material for absorbent personal care products.
