Abstract:
The present invention is a method of applying a chemical treating agent to a cellulose web. The invention is further a means of increasing the bulk, absorbency and pattern definition in an embossed cellulose web without losing softness in the web. Finally, the invention includes products produced by the foregoing processes.
Abstract:
The present invention relates to a soft, thick, single-ply tissue and to a process for the manufacture of such tissue product having a basis weight of at least about 15 lbs./3,000 square foot ream and having low sidedness, said tissue exhibiting a specific total tensile strength of between 40 and 75 grams per 3 inches per pound per 3000 square feet ream, a cross direction specific wet tensile strength of between 2.75 and 7.5 grams per 3 inches per pound per 3000 square feet ream, the ratio of MD tensile to CD tensile of between 1.00 and 2.75, a specific geometric mean tensile stiffness of between 0.5 and 1.2 grams per inch per percent strain per pound per 3000 square feet ream, a ratio of product cross direction stretch to base sheet cross direction stretch of at least about 1.4, a friction deviation of less than 0.225, and a sidedness parameter of less than 0.275.
Abstract:
The present invention is a method of making an ultra soft, multi-ply tissue from non-premium furnish using wet press technology and the product produced thereby.
Abstract:
The present invention is a method of manufacturing a one-ply absorbent paper product such as a bathroom tissue. The tissue combines high strength and softness along with low sidedness. The paper product is produced as a stratified product using furnishes supplied from different headboxes. The paper is manufactured as a wet pressed, creped product. The paper tissue product made by the process of this invention exhibits a sidedness parameter of less than 0.3 preferably, less than 0.225, a tensile modulus of no more than 32 grams/percent strain, a GM MMD of no more than about 0.225, and a cross direction strength of at least 200 grams per 3 inches.
Abstract:
A system for embossing a substantially continuous web of material including a supply for supplying at least one substantially continuous web of material, feeding the substantially continuous web of material, an embossing device for embossing a predetermined pattern in the web material and a take-up device for taking-up the embossed web material; wherein at least one roll of the system includes an elongated core formed of a substantially rigid material and an elongated sleeve formed of a material less rigid than the elongated core with the elongated sleeve being releasably secured to the core such that the elongated sleeve is axially and circumferentially fixed with respect to the core when in operation and can be selectively axially removed from the core. Preferably, the sleeve includes an embossing pattern laser engraved thereon so as to permit the embossing pattern being run by the system to be readily changed.
Abstract:
A one-ply paper tissue product and a method of making a one-ply paper product combining high strength and softness along with low sidedness. The paper tissue product exhibits a sidedness parameter of less than 0.3 preferably, less than 0.225, a tensile modulus of no more than 32 grams/percent strain, a GM MMD of no more than about 0.225, and a cross directional strength of at least 200 grams per 3 inches. In stratification tissues, these properties are obtained by control of stratification, particularly, chemical stratification and stratification of furnish when appropriate. The tissue has a sidedness parameter value of less than 0.3, preferably, about 0.15 to about less than 0.225. In homogenous tissue, these properties are obtained by adding a strength enhancing agent to separate furnish sources prior to the funish sources being combined, and further, optionally adding the softener to the nascent web.
