matter are recited in representative claims 24, 25, 26 and 27 which are
reproduced below:
24. A method for making a moist wipe for delivering a cationic
functional agent in an aqueous medium to an animate or
inanimate surface for a desired efficacy, which comprises
forming a bonded non-woven web comprising cellulosic fibers
and having an anionic surface charge not greater than 1.2 meq
per kilogram, and adding about one to three times the dry
weight of the web an aqueous imbuement carrying a cationic
functional agent at a concentration of about 6 milli-equivalents
per liter or less and being partially adsorbed by the web,
whereby the amount of said agent remaining in the free
imbuement is deliverable to the surface in sufficient quantity
for the desired efficacy.
25. The method according to claim 24 wherein said cationic
functional agent is a monomeric cationic functional agent.
26. The method according to claim 24 or claim 25 further
including applying to at least one surface of said web a
polymeric binder containing a non-ionic surfactant.
27. The method according to claim 24 or claim 25 further
including applying to at least one surface of said web a
polymeric binder containing a cationic surfactant.
