  • Publication number: 20170356109
    Abstract: A top sheet for an absorbent personal care product is a water-permeable composite web produced by hydro-entangling a web of chemical free natural and/or cellulosic staple fibers and/or blend of natural and cellulosic staple fibers and a web of man-made continuous filament yards such that a first side of the composite web exposes the chemical free natural and/or cellulosic staple fibers and/or blend of natural and cellulosic staple fibers and an opposite second side of the composite web has the man-made continuous filament yarns. The web of chemical free natural and/or cellulosic staple fibers and/or blend of natural and cellulosic staple fibers is hydrophilic and the web of man-made continuous filament synthetic yarns is hydrophobic. The composite web weights between about 20 gsm and about 40 gsm.
