Patent number: 6887348Abstract: Spirally wound paper products are disclosed having desirable roll firmness characteristics and softness properties. The rolled products can be made from a single ply tissue web formed according to various processes. Once formed, the tissue web is subjected to a shear-calendering device that increases the fuzz-on-edge properties of the web and preserves the bulk of the web when wound.Type: GrantFiled: November 27, 2002Date of Patent: May 3, 2005Assignee: Kimberly-Clark Worldwide, Inc.Inventors: Michael Alan Hermans, Clayton C. Troxell, Tammy L. Baum, Sharon S. Chang, James Leo Baggot

Patent number: 6888045Abstract: A fibrous material and a method of producing it, the material is mainly intended to be incorporated in an absorbent article and comprises a layer of continuous fibers, so-called tow, which have been bonded together in points, lines or spots in a bonding pattern, but otherwise are substantially unbonded to each other. The tow layer is bonded with at least two bonding patterns: a first relatively strong and diffuse bonding pattern, and a second more distinct second bonding pattern. Bonding of at least the first bonding pattern takes place by thermobonding, wherein a pattern roll is used which provide the desired bonding patterns. In the first welding step the pattern roll is driven at a higher speed than the feeding speed of the tow layer, so as to create a relatively diffuse and strong bonding pattern.Type: GrantFiled: September 6, 2002Date of Patent: May 3, 2005Assignee: SCA Hygiene Products ABInventors: Johan Wahlström, Jan Wästlund-Karlsson

Patent number: 6884492Abstract: The invention relates to a roll constituted by a plurality of tissue paper sheets each having a specific surface weight between 10 and 40 g/m2 and exhibiting thick zones (4) separated over at least 90% of their periphery by thinner zones (5). According to the invention, and as regards at least the outermost turns of the roll, the thick zones are at least partly superposed one on the other in a way to add the thicknesses cumulatively and hence to create height differentials on the roll's outside. The invention also relates to a method for making a roll, wherein a strip composed of a plurality of juxtaposed tissue paper sheets exhibiting thick zones separated by thinner zones will be wound on itself. According to the invention, the winding of the roll is such that the thick zones (4) of the outermost roll turns are at least partly superposed in order to constitute a salient topography on the roll's outside.Type: GrantFiled: August 8, 2003Date of Patent: April 26, 2005Assignee: Georgia-Pacific FranceInventors: Michel Basler, Sébastien Jeannot, Pierre Laurent

Patent number: 6860968Abstract: A process for producing tissue webs is disclosed. More particularly, the present invention is directed to an improved process for drying webs. According to the present invention, a formed web still containing a substantial amount of moisture is passed through a nip formed between a press roll and a heated drum. When passed through the nip, the web is placed on a porous fabric. The web is then carried through the nip for a period of time and subjected to temperatures and pressures sufficient to create a steam front which travels through the web and expels a significant amount of moisture from the web through the porous fabric.Type: GrantFiled: May 24, 2000Date of Patent: March 1, 2005Assignee: Kimberly-Clark Worldwide, Inc.Inventors: Strong Chuang, Ken Kaufman, Jay Hsu

Patent number: 6855229Abstract: Disclosed is a composition for softening a wet laid cellulosic structure. A particularly preferred structure is an absorbent tissue. Further disclosed are tissue structures softened using the composition. The composition includes an effective amount of a softening active ingredient; a vehicle in which the softening active ingredient is dispersed; an electrolyte dissolved in the vehicle; and a bilayer disrupter. The electrolyte and the bilayer disrupter cooperate to cause the viscosity of the composition to be less than the viscosity of a dispersion of the softening active ingredient in the vehicle alone. Preferably, the softening active ingredient is a quaternary ammonium compound with the formula: (R1)4-m—N+—[(CH2)n—Y—R3]mX? the vehicle is water, the electrolyte is calcium chloride, and the bilayer disrupter is a nonionic surfactant. Also disclosed is a method of using the compound by adding it at a use concentration to the wet end of a papermaking process.Type: GrantFiled: January 16, 2004Date of Patent: February 15, 2005Assignee: The Procter & Gamble CompanyInventors: David D.
