  • Patent number: 9945076
    Abstract: The present invention provides for a method of producing a creped paper and the crepe paper products made using this method. The method includes treating the surface of a crepe fiber web and/or surface of a Yankee drum dryer or cylinder with compositions containing a combination of hydrophobes and surfactants and wherein these compositions have been subjected to physical treatments to reduce the mean particle size to about 1 micron (?m) or less.

  • Patent number: 9121137
    Abstract: A dispersible article and methods of making the same. The article has a web of fibers and a dried binder in contact with the fibers. The web of fibers has a basis weight of from about 10 gsm to about 150 gsm. The dried binder has a polyfunctional aldehyde and a primary polymer. The primary polymer has at least one functional group that is reactive with the fibers or the polyfunctional aldehyde. The fibers have at least one functional group that is reactive with the polyfunctional aldehyde or the primary polymer. The article has a cross direction wet tensile strength after 15 minutes of aqueous saturation that is at least about 30% of an initial cross direction wet tensile strength. The article is flushable.
