D21H27/00
Fibrous Elements and Fibrous Structures Employing Same
Fibrous elements, such as filaments, and more particularly to fibrous elements employing a polymer and a wetting agent, methods for making such fibrous elements, fibrous structures employing such fibrous elements, methods for making such fibrous structures and packages containing such fibrous structures are provided.
FIBROUS STRUCTURES AND METHODS FOR MAKING SAME
Novel fibrous structures that contain filaments, and optionally, solid additives, such as fibers, for example wood pulp fibers, sanitary tissue products comprising such fibrous structures, and methods for making such fibrous structures and/or sanitary tissue products are provided.
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.
SANITARY TISSUE PRODUCT ROLLS
Sanitary tissue product rolls that exhibit novel combinations of physical properties, such as Moment of Inertia, Roll Density, and optionally Roll Diameter, such that the sanitary tissue product rolls meet consumers' needs, and method for making such novel sanitary tissue product rolls and marketing such novel sanitary tissue product rolls are provided.
Absorbent structures with high absorbency and low basis weight
Absorbent product including a laminate of at least two plies, wherein the absorbent product has a measured Valley Volume parameter greater than 11 microns and a Pit Density of greater than 25 pockets per sq. cm.
Tissue products formed from multi-apex emboss elements and methods for producing the same
Products having improved emboss definition, emboss visibility, and perceived softness are described. The tissue products comprise an emboss pattern including multi-apex, high aspect ratio embossing elements that do not suffer from the prior art issues of bunching, puckering and folding. When included in a multi-ply product, the embossed tissue also possesses less adhesive than prior art patterns resulting in a product with improved softness and drape.
Expanded slit sheet cushioning products with novel reduced dimension slit patterns
In the preferred embodiments, the present invention provides substantially improved slit sheet cushioning products by advantageously combining novel paper properties with novel slit patterns for improved features and characteristics. In some illustrative and non-limiting example embodiments, cushioning products of the present invention can include, e.g., a novel slit sheet material in combination with extensible paper employed as, e.g., a cushioning pad or as cushioning within an envelope product, wherein the cushioning product can be substantially more resilient, but, yet, e.g., thinner for better utilization of space.
Sanitary tissue product rolls
Sanitary tissue product rolls that exhibit novel combinations of physical properties, such as Moment of Inertia, Roll Density, and Roll Diameter, such that the sanitary tissue product rolls meet consumers' needs, and method for making such novel sanitary tissue product rolls and marketing such novel sanitary tissue product rolls are provided.
LAYERED FIBROUS STRUCTURES
Layered fibrous structures and methods for making same are provided.
Scoring rule for forming a folding score on a sheet material
A scoring rule for forming a folding score on a sheet material includes a pair of score members with a scoring surface portions with individually asymmetrical flat outer surfaces extending at an angle. The score members press against a first side of the sheet material to cause a pair of laterally spaced fold score lines to be formed on the first side of the sheet material by the scoring surface portions. As the scoring rule engages the sheet material, a second, opposite side of the sheet material is compressed such that rubber-type material of an anvil of the rotary press bulges towards and forces the sheet material into an area between the pair of score members causing a self-contained single longitudinally inwardly extending groove to be formed on the second, opposite side of the sheet material along a line parallel to and positioned between the laterally spaced score lines.
