  • Soft absorbent tissue treated with a chemical composition
    Patent number: 6599394
    Abstract: A tissue product having improved hand feel and good wettability is produced by printing onto one or both sides of the tissue an aqueous emulsion containing a hydrophilically-modified amino-functional polydimethylsiloxane. The hydrophilically-modified amino-functional polydimethylsiloxane structure has one or more pendant groups containing an ethylene oxide moiety and/or propylene oxide moiety.
    Type: Grant
    Filed: March 14, 2002
    Date of Patent: July 29, 2003
    Assignee: Kimberly-Clark Worldwide, Inc.
    Inventors: Kou-Chang Liu, Amber Marie Fortune, Geoffrey Fenn Carlow, Timothy Dale Ferguson, Roger Edward Wendler, Jr., Heath David Van Wychen, Daniel John VanderHeiden
  • Soft absorbent tissue containing derivitized amino-functional polysiloxanes
    Patent number: 6514383
    Abstract: A tissue product having improved hand feel and good wettability is produced by printing onto one or both sides of the tissue an aqueous emulsion containing a derivitized amino-functional polysiloxane. The derivitized amino-functional polysiloxane structure has one or more pendant groups containing an amine derivative.
    Type: Grant

  • Uncreped tissue sheets having a high wet:dry tensile strength ratio
    Patent number: 6461476
    Abstract: The ratio of the wet tensile strength to the dry tensile strength of uncreped throughdried tissues and towels can be increased by treating the papermaking pulp with a debonder, a wet strength agent and a dry strength agent. The properties of the resulting product can be manipulated to either provide a product with normal degree of softness (as measured by the machine direction sheet stiffness) and a high wet strength, or a normal degree of wet strength and a higher degree of softness.

  • SOFT ABSORBENT TISSUE
    Publication number: 20020112835
    Abstract: A tissue product having improved hand feel and good wettability is produced by printing onto one or both sides of the tissue an aqueous emuslion containing a hydrophilically-modified amino-functional polydimethylsiloxane. The hydrophilically-modified amino-functional polydimethylsiloxane structure has one or more pendant groups containing a terminal amine functionality and at least one pendant group containing an ethylene oxide moiety.
    Type: Application

  • Process for compressing a web which contains superabsorbent material
    Patent number: 6214274
    Abstract: A process and apparatus for compacting a web (12) which contains a superabsorbent material (32) can include a plasticizing of the superabsorbent material contained in the web (12), and a compressing of the web (12) at a relatively low pressure. The selected, low pressure can be arranged to substantially avoid an excessive fracturing of the superabsorbent material.
