  • Patent number: 6054020
    Abstract: Amine-modified polysiloxanes are applied to the opposite outer surfaces of a tissue product, such as the two outer surfaces of a 3-ply facial tissue, providing improved softness to the surfaces and a degree of hydrophobicity to prevent wet through of liquids during use. However, the degree of hydrophobicity is controlled by the chemical structure of the amine-modified polysiloxane and/or by blending the amine-modified polysiloxane with a more hydrophilic modified polysiloxane such that liquid is still allowed to enter the tissue structure in a reasonably short time to be absorbed by the center ply, but the absorption in combination with the hydrophobicity of the other outer surface substantially delays the liquid from passing completely through the tissue product.

  • Patent number: 6036909
    Abstract: Cellulosic webs can be embossed using an extended nip structure with embossing means in a controlled nip dwell zone. Single and multiply wipes and towels produced by plying together two or more such webs can be embossed. Webs having common caliper and basis weight can be processed using the extended nip structure with an appropriate embossing means. The tendency of the embossed relief to relax and disappear after processing can be substantially alleviated by controlling dwell time to ensure reliable embossing.

  • Patent number: 6030675
    Abstract: The invention relates to tissue products having improved softness properties and methods of making them. Specifically, improved softness is achieved by incorporating a cationic silicone amidoamine ester or phosphate and, optionally, one or more softeners/debonders into the fiber furnish at the wet end of the tissue machine prior to formation, followed by an optional topical treatment with a cationic silicone amidoamine ester or phosphate and/or one or more softeners/debonders after the tissue web is formed. The result is a tissue product with added bulk and a smooth surface feel, both properties contributing to improved softness characteristics.

  • Patent number: 6017417
    Abstract: Throughdried tissue products such as facial tissue, bath tissue, and paper towels are made using a throughdrying fabric having from about 5 to about 300 machine direction impression knuckles per square inch (per 6.45 square centimeters) which are raised above the plane of the fabric. These impression knuckles create corresponding protrusions in the throughdried sheet which impart a significant amount of cross-machine direction stretch to the sheet. In addition, other properties such as bulk, absorbent capacity, absorbent rate and flexibility are also improved.

  • Patent number: 5990377
    Abstract: A dual-zoned, three-dimensional, resilient absorbent web is disclosed which is suitable as body-side liner for absorbent articles such as feminine pads, diapers and the like. When used as a liner in absorbent articles, the dual-zoned web combines the advantages of apertured films and soft, nonwoven cover layers in one structure while still being inherently hydrophilic. The liner comprises a web of wet-resilient, hydrophilic basesheet having a three-dimensional topography comprising elevated regions onto which hydrophobic matter is deposited or printed and a plurality of spaced apart depressed regions. In a preferred embodiment, the hydrophobic matter applied to the elevated regions of the basesheet comprises hydrophobic fibers in a contiguous nonwoven web which has been apertured or provided with slits or other openings, such that the apertures or openings overlay a portion of the depressed regions.

  • Patent number: 5948507
    Abstract: Absorbent articles containing absorbent cores of fluff pulp frequently contain wrinkles in the absorbent core that run from side to side of the article, typically normal to the machine direction in the manufacturing process. Side-to-side wrinkles are deleterious in that they provide large flow channels for urine or other body fluids to escape to the edge of the article. Frequently, such wrinkles are present after manufacturing, before the article has been folded or worn. The cause of the wrinkles is believed to be due to natural instabilities during compression of the fluff pad shortly after it is formed. Means for reducing cross-directional wrinkles include the use of grooved, drilled, or patterned compression rolls to densify the fluff pulp while providing opportunities for reduced in-plane displacement during compression or, if in-plane displacement does occur, providing paths for cross-directional displacement as well as machine-direction displacement so that continuous CD wrinkles cannot form.

  • Patent number: 5944273
    Abstract: A uniformly wound parent roll of soft, high bulk tissue has greater uniformity in sheet basis weight, machine direction stretch and bulk when compared to parent rolls wound by conventional winding methods. The method involves carrying the tissue sheet on a relatively air impermeable transfer belt which traverses an unsupported span between two winding drums. The sheet is transferred from the transfer belt to the parent roll as the parent roll is urged against the sheet/transfer belt at a point within the unsupported span. The resulting deflection of the transfer belt is detected and, in response, the reel spool position is controllably changed to maintain the deflection within predetermined limits. The tension of the sheet is controlled by the predetermined differential speed between the outer most surface of the parent roll and the transfer belt.

  • Patent number: 5935383
    Abstract: The invention is a method for improving the efficiency of aqueous cationic wet strength additives by pretreating cellulose surfaces with reactive anionic compounds, thus providing the cellulose surface with additional anionic sites suitable for retaining a high proportion of said cationic wet strength additives on the cellulose. The wet strength additives on the cellulose surface are cured or reacted with the cellulose surface. The resulting fibrous material has unusually high wet strength with unusually low doses of cationic wet strength additive. The preferred reactive anionic compounds comprise compounds having a reactive group suitable for covalent bonding to hydroxyl groups on cellulose, and further having sulfonic or other anionic end groups capable of attracting cationic wet strength compounds in aqueous solution. The invention also includes means of preventing photoyellowing of high-yield fibers while simultaneously improving wet strength performance.

  • Patent number: 5932068
    Abstract: Soft throughdried tissues, which are sufficiently soft to serve as premium bathroom tissues, can be made without the use of a Yankee dryer. The typical Yankee functions of building machine direction and cross-machine direction stretch are replaced by a wet end rush transfer and the throughdrying fabric design, respectively. It is particularly advantageous to form the tissue with chemimechanically treated fibers in at least one layer. The resulting tissues have high bulk (about 6 cubic centimeters per gram or greater) and low stiffness.

  • Patent number: 5928470
    Abstract: Metal oxides or metal hydroxides, such as titanium dioxide, are incorporated into papermaking fibers by absorbing an organometallic compound into the fiber walls while the fibers are dry or slurried with a non-aqueous solvent and thereafter contacting the ester-containing fibers with water to precipitate the metal oxides or metal hydroxides. The resulting modified fibers can provide greater opacity and other improved properties to papers made from such fibers.
