ABSTRACT:
Nonwoven fibrous sheets bonded with 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 boric acid. The boric acid imparts improved wet tensile strength to the sheet during storage and use by the consumer but may be safely disposed of, after use, by flushing in plain water without danger of clogging the plumbing system. Instead of boric acid solution, one may employ for the indicated purpose a non-alkaline aqueous solution of a salt which acts as a precipitating or gelling agent for polyvinyl alcohol, said salt being one having an acid to neutral pH on hydrolysis.
