Abstract:
Disclosed is a dispersible adhesively bonded wet tissue laminate and more particularly a dispersible wet wipe comprising two or more adhesively bonded tissue plies. Generally, the wipe comprises first, and second tissue plies adhesively bonded to one another by an adhesive, particularly a triggerable binder, disposed at the interface of the plies. The first and second tissue plies preferably comprise fibrous tissue plies and more preferably wet-laid tissue plies consisting essentially of conventional papermaking fibers. The adhesively bonded laminates are generally strong enough to withstand use, such as having a geometric mean wet tensile strength (GMWT) greater than about 250 g/in, but disperse quickly in water, such as having a Slosh Time less than about 60 minutes.
