20080230195 | Tissue products containing non-fibrous polymeric surface structures and a topically-applied softening composition - Soft tissue products with a good rate of absorbency, such as facial and bath tissue, are provided by forming a tissue sheet with a non-fibrous polymeric surface structure and thereafter topically applying a softening composition comprising a polysiloxane, a fatty alkyl derivative and glycerin. The non-fibrous polymeric surface structure is created by applying an additive composition to the surface of a tissue sheet prior to or after drying. The additive composition can be an aqueous dispersion containing an alpha-olefin polymer, an ethylene-carboxylic acid copolymer, or mixtures thereof. The alpha-olefin polymer may comprise an interpolymer of ethylene and octene, while the ethylene-carboxylic acid copolymer may comprise ethylene-acrylic acid copolymer. | 09-25-2008 |
20080302498 | Process for incorporating poorly substantive paper modifying agents into a paper sheet via wet end addition - Synthetic co-polymers having moieties capable of forming hydrogen bonds, ionic bonds, or covalent bonds with cellulose fibers and paper modifying moieties capable of modifying a paper sheet are disclosed. These synthetic co-polymers are derived from the reaction of an aldehyde functional polymer and an aldehyde reactive paper modifying agent containing a non-hydroxyl aldehyde reactive functional group. | 12-11-2008 |
20100243187 | Method for Applying Chemical Additives to Pulp During the Pulp Processing and Products Made by Said Method - Pulp fibers can be treated with chemical additives with a minimal amount of unretained chemical additives present later in the process water. The present invention is a method for preparing chemically treated pulp fiber. A fiber slurry is created comprising process water and pulp fibers. The fiber slurry is transported to a web-forming apparatus of a pulp sheet machine thereby forming a wet fibrous web. The wet fibrous web is dried to a predetermined consistency thereby forming a dried fibrous web. The dried fibrous web is treated with a chemical additive thereby forming a chemically treated dried fibrous web. The dried fibrous web contains chemically treated pulp fibers. The chemically treated pulp fibers retain from between about 10 to about 100 percent of the applied amount of the chemical additive when the chemically treated pulp fibers are redispersed in water. | 09-30-2010 |
20140048224 | Absorbent Barrier Tissue - In general, the present disclosure is directed to creped tissue webs, and products produced therefrom. The creped webs and products are strong, soft, and have improved strike-through and absorbency properties. The improvement in both strike-through and absorbency is achieved in-part by increasing the basis weight of the web, while at the same time reducing the creping composition add-on levels. | 02-20-2014 |
20140050889 | High Basis Weight Creped Tissue - In general, the present disclosure is directed to creped tissue webs, and products produced therefrom. The creped webs and products are strong, soft, and have fine crepe structure, such as less than about 12, measured as % COV at a STFI wavelength of 16 to 32 mm, using the test method set forth herein. Fine crepe structure is achieved even at basis weights in excess of 16 gsm per ply. | 02-20-2014 |
20140050890 | High Basis Weight Tissue with Low Slough - Low slough, high basis weight tissue webs and products are provided. The tissue webs generally have basis weights greater than about 16 grams per square meter (gsm), while maintaining less than about 4 mg of slough. All while yielding tissue products that are both thick and soft. | 02-20-2014 |
20150176222 | MULTILAYERED TISSUE HAVING REDUCED HYDROGEN BONDING - The disclosure provides a multilayered tissue web comprising treated cellulosic fibers selectively disposed in one or more layers, wherein the tissue layer comprising treated fibers is adjacent to a layer comprising untreated fiber and which is substantially free from untreated fiber. Generally the treated fibers have a rate of substitution of about 0.02 to 0.07. In this manner, the disclosure provides a multi-layered tissue web having treated fiber selectively incorporated therein, where the tissue web has basis weight greater than about 10 grams per square meter (gsm), such as from about 10 to about 50 gsm, a sheet bulk greater than about 8 cc/g, such as from about 8 to about 15 cc/g and Stiffness Index less than about 15, such as from about 8 to about 12. | 06-25-2015 |
20160002861 | TWO SIDED MULTI-PLY TISSUE PRODUCT - The invention provides a multi-ply tissue product having different surface characteristics on each side of the product. The multi-ply tissue product may be formed from two or more plies where one surface is formed by a substantially smooth creped ply and the other surface is formed by a textured through-air dried ply. In this manner the tissue product may be used for both personal care, which requires a soft and smooth surface, and general household wiping, which requires a rough, durable surface. | 01-07-2016 |
