Dispersible moist wipe and method of making

A dispersible moist wipe includes regenerated cellulose fibers in an amount equal to or less than 20 percent by weight and natural cellulose fibers in an amount equal to or greater than 80 percent by weight. At least 50 percent of the natural cellulose fibers are fibrillated. The regenerated cellulo...

More Information
Summary:A dispersible moist wipe includes regenerated cellulose fibers in an amount equal to or less than 20 percent by weight and natural cellulose fibers in an amount equal to or greater than 80 percent by weight. At least 50 percent of the natural cellulose fibers are fibrillated. The regenerated cellulose fibers and the natural cellulose fibers are hydroentangled such that the web has a wet CD tensile strength of at least 200 grams per inch. A method of making a dispersible nonwoven sheet includes dispersing natural cellulose fibers and regenerated cellulose fibers in a liquid medium to form a liquid suspension and depositing the liquid suspension over a forming surface to form a nonwoven web. The natural cellulose fibers and regenerated cellulose fibers of the web are hydroentangled using a plurality of hydroentangling jets.
