Patent ID: 7101456

Claim:
A method of making a wet wipe comprising: forming a substrate of fibrous material; applying to said substrate a binder composition for binding said fibrous material into an integral web to form a wipe, said binder composition comprising a composition having the structure: wherein x=1 to about 15 mole percent; y=about 60 to about 99 mole percent; and z=0 to about 30 mole percent; Q is selected from C 1 –C 4 alkyl ammonium, quaternary C 1 –C 4 alkyl ammonium, and benzyl ammonium; Z is selected from —O—, —COO—, —OOC—, —CONH—, and —NHCO—; R 1 , R 2 , R 3 are independently selected from hydrogen and methyl; R 4 is C 1 –C 4 alkyl; R 5 is selected from hydrogen, methyl, ethyl, butyl, ethylhexyl, decyl, dodecyl, hydroxyethyl, hydroxypropyl, polyoxyethylene, and polyoxypropylene; and wherein the binder composition is dispersible in water containing up to about 200 ppm of Ca 2+ and/or Mg 2+ ions; and applying to said wipe a wetting solution to form a wet wipe, wherein the wetting solution contains an amount of an insolubilizing agent sufficient to render the the binder composition insoluble in said wetting solution.
