摘要： An absorbent article having a liquid-handling system includes a liquid permeable bodyside liner; a liquid impermeable outer cover; and an absorbent core disposed between the liner and the outer cover, wherein the absorbent core has a longitudinal direction, wherein the absorbent core includes a layer of a three-dimensionally patterned, wetlaid, cellulosic tissue nonwoven material, and wherein the layer includes longitudinal ridges and grooves. The absorbent core can include multiple layers of a three-dimensionally patterned, wetlaid, cellulosic tissue nonwoven material, wherein each layer of the multiple layers includes longitudinal ridges and grooves, and wherein the multiple layers are joined by lines of embossing, such lines of embossing extending in the longitudinal direction. Each layer of the multiple layers can include embossed longitudinal ridges and grooves.

摘要： A method for making a permanently wettable material is disclosed. The method includes selecting a plurality of non-polar polymer fibers (12) wherein each fiber has a surface (16), depositing a hydrophilic polymer mixture (14) on the non-polar polymer fiber surface to form a shell. The hydrophilic polymer mixture (14) includes a cross-linkable and graftable epoxy-containing polymer, such as, poly(glycidyl methacrylate-co-ethylene glycol methacrylate) copolymer (PGMA-co-POEGMA), a high weight average molecular weight polyethylene glycol (PEG), and a surfactant. A permanently wettable material is also disclosed that includes a non-polar polymer-based web (10) having fibers (12) with a surface (16). A hydrophilic polymer mixture (14) forms a shell on the non-polar polymer fiber surface (16). The hydrophilic polymer mixture (14) includes a poly(glycidyl methacrylate-co-ethylene glycol methacrylate) copolymer (PGMA-co-POEGMA), a high weight average molecular weight polyethylene glycol (PEG), and a surfactant.
