Abstract
A water dispersible nonwoven web is disclosed. The nonwoven web is produced in an airlaying process and contains pulp fibers mixed with water soluble fibers. The water soluble fibers may be, for instance, polyvinyl alcohol fibers. The nonwoven web may be pre-saturated with a cleaning solution. Once pre-saturated with a cleaning solution, the wiping product is particularly well suited to cleaning and/or disinfecting surfaces, such as toilet seats prior to use. Because the nonwoven web is water dispersible, the wiper may be disposed of by being flushed down a toilet.
