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.

Creping adhesive modifier and process for producing paper products

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. A method of forming a multi-ply tissue involves conveying a base sheet through a nip between an impression roll and a pattern roll to produce an embossed base sheet having a back side possessing projections, applying adhesive to the back side of the embossed base sheet at spaced apart locations, and applying a flat backing sheet to the back side of the embossed base sheet so that the backing sheet adheres to the back side of the embossed base sheet at said spaced apart locations. A method of producing an embossed tissue involves successively conveying a base sheet through a nip between a first impression roll and a pattern roll, and conveying the base sheet through another nip between the pattern roll and a second impression roll, wherein the second impression roll is made of rubber having a lower hardness than the rubber from which the first impression roll is made.

Multi-ply absorbent paper product having impressed pattern

Kitchen roll toweling having surprising softness, absorbency and bulk is formed from a furnish comprising long cellulosic fiber having: (i) average weight-weighted fiber length of at least 2.5 mm; coarseness at least 15.5 mg/100 mm; and a Canadian Standard freeness of at least 600 ml combined with (ii) short cellulosic fiber having an average weight-weighted fiber length of at most 1.9 mm having a Canadian Standard freeness of at least 500 ml in a weight ratio of short fiber to long fiber of at least 0.25 to 1.0 to form a nascent web having a consistency in the range from about 10% to about 35% which is rush transferred from one fabric to another at a speed differential of at least about 15%; and creping the web from a Yankee dryer while controlling the real crepe to at most 3% and thereafter converting the web to form a two ply product having a basis weight of at least 29 lb/rm and caliper of at least 220 mils/8 sheets.

High basis weight TAD towel prepared from coarse furnish

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.

Method for maximizing water removal in a press nip

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.

Wet crepe throughdry process for making absorbent sheet and novel fibrous products

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.

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.
