ABSTRACT:
A process for impregnating a resin into a substrate to form a web. The resin is impregnated into one side of the web, so that the other side remains exposed. This arrangement allows the exposed side of the web to be dispersible in water, while the impregnated side is water resistant. The impregnation may occur in zones and comprise one material or two or more materials. The resulting web is useful as a backsheet in disposable absorbent articles wherein it is desired to have a barrier that is impermeable to body fluids, yet flushable for disposal.
