  • Patent number: 11542664
    Abstract: A process for making a multi-ply dispersible wipe includes providing a first web and a second web, each web comprising cellulose fibers; superposing the first web over the second web; applying an aqueous solution to at least the first web; after the aqueous solution is applied to the first web, crimping the second web to the first web to create a composite web; cutting or perforating the composite web to define a plurality of multi-ply wet wipes; and packaging the composite web/wet wipes into a package.
    Type: Grant
    Filed: December 20, 2017
    Date of Patent: January 3, 2023
    Assignee: KIMBERLY-CLARK WORLDWIDE, INC.

  • Patent number: 10538879
    Abstract: 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.

  • Patent number: 9809931
    Abstract: The present disclosure is generally directed to a dispersible moist wipe comprising hydroentangled fibers and a binder composition. The moist wipe demonstrates high initial wet strength while maintaining effective dispersion in an aqueous environment. The moist wipe has potential application as a flushable surface cleaning product and/or a flushable cleansing cloth.
