Fibrous Structures and Methods for Making Same

a technology of fibrous structures and fibroblasts, applied in the field of fibroblasts, can solve the problems of two calibration methods, the emtec tissue softness analyzer had apparently been considered unsuitable for measuring wood pulp fiber-containing fibrous structures, and the formulators failed to appreciate, etc., to achieve the effect of improving surface properties

Benefits of technology

[0011]The present invention fulfills the needs described above by providing fibrous structures and single- or multi-ply sanitary tissue products comprising such fibrous structures, for example fibrous structures and/or single- or multi-ply sanitary tissue products that exhibit improved surface properties, such as softness, as measured according to the Emtec Test Method described herein, and more particularly to such fibrous structures and/or single- or multi-ply sanitary tissue products comprising at least one...

Problems solved by technology

Another problem with the past formulators' measurements using the EMTEC Tissue Softness Analyzer is that the measurements are very dependent upon which of two calibration methods is used in calibrating the EMTEC Tissue Softness Analyzer.
Apparently, the past formulators failed to appreciate this fact and didn't indicate which of the two calibration methods were used or even if the EMTEC Tissue Softness Analyzer was calibrated at all.
In addition to the problems discussed above with the past formulators' measurements of creped surface, wood pulp fiber-containing fibrous structures, the EMTEC Tissue Softness Analyzer had apparently been considered not suitable t...

Fibrous Structure Comprising Starch Filaments / Wood Pulp Fibers in a Single Ply Tissue Web

[0258]A polymer melt composition comprising 79% IPG starch commercially available from Ingredion Inc., 16% Ethylex 2035 (ethoxylated starch) commercially available from Tate & Lyle PLC, 0.6% Aerosol AOT-70PG (sulfosuccinate surfactant) available from Cytec Industries, Inc., 0.6% Hyperfloc NF301PWG (non-hydroxyl polymer), commercially available from Hychem Inc., 3.1% Urea glyoxal adduct crosslinking agent (dihydroxyethyleneurea) (containing less than 2% by weight of a base, for example triethanolamine), 0.003% Violet CT (hueing agent) commercially available from Milliken Chemical, and 0.7% Ammonium methane sulfonate (crosslinking facilitator). The polymer melt composition is cooked at approximately 125° C. and extruded from a co-rotating twin screw extruder at approx 50% solids (50% H2O). The melt composition then passes through a heat exchanger to raise the temperature to approximately 175° C. T...

Abstract

Fibrous structures and more particularly fibrous structures containing a plurality of hydroxyl polymer fibrous elements, for example hydroxyl polymer filaments, such that the fibrous structures exhibit improved surface properties compared to known fibrous structures and methods for making such fibrous structures are provided.

Description

FIELD OF THE INVENTION[0001]The present invention relates to fibrous structures and more particularly to fibrous structures that exhibit improved surface properties, such as softness, compared to known fibrous structures and methods for making such novel fibrous structures.BACKGROUND OF THE INVENTION[0002]Surface properties, especially softness, of fibrous structures, for example sanitary tissue products, such as toilet tissue, are important to consumers.[0003]Formulators in the past have imparted crepe to a surface of the fibrous structure, such as by creping the fibrous structure off a dryer or Yankee and / or by other means of foreshortening the fibrous structure, such as rush transfer steps in making the fibrous structure, to improve softness of fibrous structure the exterior surfaces of a sanitary tissue product comprising the creped fibrous structure. Formulators have tried to utilize the EMTEC Tissue Softness Analyzer from Emtec Electronic GmbH of Leipzig, Germany to measure th...
