ABSTRACT:
Nonwoven fibrous sheets impregnated with latices of polyvinyl acetate or its copolymers containing polyvinyl alcohol, intended for use in pre-moistened condition as skin cleansing tissues, are folded and packaged in closed containers or in individual sealed water impervious envelopes; said packaged sheets being maintained in contact with a dilute aqueous solution of a precipitating or gelling agent for polyvinyl alcohol, such as boric acid. The agent imparts improved wet tensile strength to the sheet during storage and use by the consumer but permits the sheet to be safely disposed of, after use, by flushing in plain water without danger of clogging the plumbing system.
