20120028004 | Low-Density Web And Method of Applying An Additive Composition Thereto - Sheet-like products, such as tissue products made from a low-density web, are disclosed containing an additive composition. The additive composition, for instance, comprises an aqueous dispersion containing an alpha-olefin polymer, and an ethylene-carboxylic acid copolymer. The additive composition may be applied to the surface of the web so that it does not thoroughly or even substantially penetrate the web. For instance, the additive may be applied to one or both surfaces of the web by gravure printing, press coating, spraying or the like. The additive composition may improve the strength of the tissue web and/or improve the perceived softness of the web. | 02-02-2012 |
20120160400 | Method of Indirect Application of Frothed Chemistry to a Substrate - Substrates such as tissue and nonwovens have an additive composition applied topically thereto. The additive composition, for instance, comprises a frothed aqueous dispersion or solution which is topically applied to the web through a creping process after the web has been formed. The additive composition may be applied in-line to the web as a creping adhesive during a creping operation. In the alternative, the additive composition may be added in an off-line converting process that crepes a dry pre-formed substrate material. The additive composition may improve bulk and softness of the tissue. | 06-28-2012 |

The additive composition may be applied to the surface of the web so that it does not thoroughly or even substantially penetrate the web. For instance, the additive may be applied to one or both surfaces of the web by gravure printing, press coating, spraying or the like. The additive composition may improve the strength of the tissue web and/or improve the perceived softness of the web. | 05-23-2013 |
20140034254 | HIGH BULK TISSUE COMPRISING EXPANDABLE MICROSPHERES - The disclosure relates to high bulk tissue webs containing microspheres. To form the tissue webs, a nonionic polymer dispersion, such as polyvinyl alcohol stabilized vinyl acetate-ethylene copolymer dispersion, is mixed with microspheres and incorporated into tissue webs to increase sheet bulk. | 02-06-2014 |
20140178660 | SOFT TISSUE HAVING REDUCED HYDROGEN BONDING - The present invention provides a modified cellulosic fiber having reduced hydrogen bonding capabilities. The modified fiber formed in accordance with the present invention may be useful in the production of tissue products having improved bulk and softness. More importantly, the modified fiber is adaptable to current tissue making processes and may be incorporated into a tissue product to improve bulk and softness without an unsatisfactory reduction in tensile. | 06-26-2014 |
20140357743 | Method Of Forming Creped Thin Film-Like Structures From Frothed Chemistry - A method is presented for forming a collapsed foam film-like structure, the method including positioning a composition applicator adjacent to a hot non-permeable dryer surface, producing a first frothed dispersion or frothed solution from a first dispersion or solution, applying the first frothed dispersion or frothed solution to the dryer surface, allowing the first frothed dispersion or frothed solution to convert to a collapsed foam film-like structure, and scraping the collapsed foam film-like structure from the dryer surface. The method can further include producing a second dispersion or solution, blending the first dispersion or solution and the second dispersion or solution, frothing the blended dispersion or solution, applying the blended frothed dispersion or frothed solution to the dryer surface, and allowing the frothed dispersion or frothed solution to convert to a collapsed foam film-like structure. | 12-04-2014 |
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 |
