|Title:||METHOD OF MAKING DISPERSIBLE WET WIPES VIA PATTERNED BINDER APPLICATION|
A method of making a dispersible wet wipe includes providing a web of cellulosic fibers. In one embodiment, a first binder is applied to a web surface in a coating that comprises randomly distributed deposits of the first binder. A second binder is applied an intermittent pattern on the web surface to define first regions on the first surface that include first binder but no second binder and to define second regions on the first surface that include both first binder and second binder. In a second embodiment, a first binder is applied to a web surface in a first pattern, and, after applying the first binder, a second binder is applied to the web surface in a second pattern that is different than the first pattern. In a third embodiment, a binder is applied to a web surface in a pattern, the pattern having first regions and second regions, wherein the add-on level of the binder in the first regions is lower than the add-on level of the binder in the second regions.
