Abstract: The present invention is a method for maximizing water removal from an absorbent web in a press nip. The present invention uses a pressing unit having a blanket with a void volume and with a pressure profile that maximizes water removal in the press section or on the Yankee dryer of a paper machine. The pressure profile of the pressing unit according to the present invention has a very steep pressure drop at and/or following the exit of a pressure distribution curve in order to maximize water removal by minimizing rewet of the web. The improved pressure profile according to the present invention results in increased water removal and/or improved line speed. The void volume further increases water removal and/or improves line speed.

Abstract: A method of forming a cellulosic web is discussed, the product of which may, for example, possess at least one of increased softness, strength, and absorbency. The method measures the total anionic charge and controls the net charge of an aqueous stream.

Abstract: An improved process for making sheet from a fibrous furnish includes: depositing the furnish on a foraminous support; compactively dewatering the furnish to form a nascent web; drying the web on a heated cylinder; creping the web therefrom and throughdrying the web to a finished product. The microstructure of the web is controlled so as to facilitate throughdrying. The product exhibits a characteristic throughdrying coefficient of from 4 to 10 when the airflow through the sheet is characterized by a Reynolds Number of less than about 1. The novel products of the invention are characterized by wet springback ratio, hydraulic diameter and an internal bond strength parameter.

Abstract: A multi-ply tissue includes a first cellulosic embossed ply having an emboss pattern applied over a portion of its surface and a second cellulosic embossed ply of tissue. The first ply is contact laminated to the second ply so that the primary adhesion between the plies of tissue is the result of contact between cellulosic fibers. The first and second plies contact one another in contact-areas, with the contact areas between the first and second plies defining compliant voids. The contact areas between the first ply and the second ply are elongated and/or rounded contact areas.

Abstract: The present invention is a through-air-drying process for producing a fibrous web that possesses not only softness and absorbency but also strength. The method of the present invention monitors and controls the overall charge in the headbox.

Abstract: The present invention relates to the use of a quaternary ammonium complex comprising at least one non-cyclic amide as a modifier for a creping adhesive used on a creping cylinder, e.g., a Yankee dryer.

Abstract: A paper product and a method of making a paper product with a glabrous surface and adapted for use either dry or for use in a manually pre-moistened condition. The paper product having temporary wet strength exhibiting an initial normalized CD wet tensile strength of at least about 75 g/3 inch strip, preferably 105 g/3 inch strip as measured by the Finch Cup Test 5 seconds after immersion and a subsequent CD wet strength of less than 1/2 as measured 10 minutes after immersion. A temporary wet strength agent comprising uncharged chemical moieties such as aldehydes, and aldehydes containing polymers, polyols and cyclic ureas or mixtures thereof in the range of from about 2 pounds per ton to about 30 pounds per ton is added to the web. Optionally starch and a cationic nitrogenous softener/debonder is added. The starch and softener/debonder are added to assist in tailor making the desired paper product having temporary wet strength.
