A method for creping paper includes applying an adhesive composition to an outer surface of a creping cylinder (Yankee cylinder) to form an adhesive coating, contacting paper with the adhesive coating, removing the paper and adhesive coating from the creping cylinder, and determining a quality of the adhesive coating. Determining the quality of the adhesive coating may include measuring a degree of cross-linking of the adhesive polymer, a concentration of the adhesive polymer in the adhesive coating, a water content of the adhesive coating, an ash content of the adhesive coating, or combinations thereof. Determining the quality of the adhesive coating may also include determining a thickness of the adhesive coating by measuring light absorbed by the coating and calculating the thickness using Beer's Law. Systems and apparatuses for determining the quality of the adhesive coating and for creping paper are also disclosed.

Method for producing nanocelluloses from a cellulose substrate

Disclosed is a method for producing nanocelluloses from a cellulose substrate including cellulose fibers, the method including the following sequence of steps: —a step of enzymatic treatment of the cellulose substrate, by bringing same into contact with at least one cleaving enzyme, then—a step of mechanical treatment of the cellulose substrate subjected to the step of enzymatic treatment, in order to delaminate the cellulose fibres and obtain the nanocelluloses. The at least one cleaving enzyme is chosen from the enzymes belonging to the family of lytic polysaccharide monooxygenases (LPMOs) capable of achieving cleavage in the presence of an electron donor. Also disclosed are the nanocelluloses obtained according to the method.

Process for making multi-ply fibrous structure containing articles

Articles, for example multi-ply fibrous structure-containing articles such as multi-ply sanitary tissue products, containing two or more fibrous structure plies, and more particularly to multi-ply articles containing two or more fibrous structure plies having a plurality of fibrous elements wherein the articles exhibit improved bulk and absorbent properties compared to known articles and methods for making same, are provided.

Fibrous structures

A fibrous structure is disclosed. The fibrous structure exhibits a plurality of discrete knuckles arranged in a pattern of repeat units. The repeat units can include a plurality of rows arranged orthogonally in an X-Y plane, each row having a portion of the discrete knuckles, and each discrete knuckle separated from adjacent discrete knuckles in a row by a distance. Each of the discrete knuckles within the repeat unit can have substantially the same shape and size; and wherein the distance between at least two adjacent discrete knuckles in each row are non-uniform such that the repeat unit exhibits varying pillow width distances along the rows in both the X and Y axes.

11760548 · 2023-09-19 ·

An extensible slit sheet paper product is produced having an expandable slit pattern that forms open cells upon expansion of the paper product. The paper product is an extensible paper having an extensibility in the range from 1-9% in the machine direction and 1-5% in the cross direction. The expansion produces an array of hexagonal cells. The expanded extensible paper can be used to wrap an object for shipping by wrapping and cushioning the object in the expanded slit sheet material. The extensible, expandable slit sheet paper can be wrapped around itself to produce a void fill product.
