Benefits of technology

The present invention provides a novel surface pattern on a sanitary tissue product's surface. This surface pattern includes a set of lines of varying-sized depressions arranged in a periodic sequence, which convey better wet properties and cleaning compared to known surface patterns. The surface pattern also includes a repeating design element with a larger dimension and a smaller dimension, such as a rhombus element, which is positioned between a set of lines formed by the depressions. The method for making a sanitary tissue product with this surface pattern is also provided.

Problems solved by technology

Therefore, the problem faced by formulators is how to make a sanitary tissue product, for example a paper towel, having a surface pattern that conveys better wet properties and / or wet usage and / or better cleaning, such as soil removal and / or soil dislodging, than known surface patterns on sanitary tissue products.

example 3

[0057]For a given size of discrete depression, for example Extra Large in Example 2 above, one or more discrete depressions 28 may be present in that position.

[0058]In one example, a line 26 of variable-sized discrete depressions 28 may comprise one or more inflection points 30 along the length of the line 26 and / or line set where the direction of the line 26 changes. The inflection point 30 may actually be a discrete depression 28 and / or a plurality of discrete depressions 28 and / or even a space between two adjacent discrete depressions 28. In Example 3 above, the inflection points may be at the small discrete depressions, for example at a minimum-sized discrete depression within the line. In another example, the inflection point may be at the largest discrete depression, for example the maximum-sized discrete depression within the line.

[0059]As shown in FIG. 3, the two lines 26 of the first set may be asymptotic to one another. In another example, the two lines 26 may be symmetric...

[0099]Examples of articles of manufacture, specifically fibrous structures; namely, paper towels for use in the comparative and inventive examples below are produced utilizing a cellulosic pulp fiber furnish consisting of about 55% refined softwood furnish consisting of about 44% Northern Bleached Softwood Kraft (Bowater), 44% Northern Bleached Softwood Kraft (Celgar) and 12% Southern Bleached Softwood Kraft (Alabama River Softwood, Weyerhaeuser); about 30% of unrefined hardwood Eucalyptus Bleached Kraft consisting of about 80% (Fibria) and 20% NBHK (Aspen) (Peace River); and about 15% of an unrefined furnish consisting of a blend of about 27% Northern Bleached Softwood Kraft (Bowater), 27% Northern Bleached Softwood Kraft (Celgar), 42% Eucalyptus Bleached Kraft (Fibria) and 7% Southern Bleached Kraft (Alabama River Softwood, Weyerhaeuser). The 55% refined softwood is refined as needed to maintain target wet burst at the reel. Any furnish preparation and refining methodology common ...

Abstract

Sanitary tissue products having a surface pattern for better wet properties and / or cleaning properties.

Description

FIELD OF THE INVENTION[0001]The present invention relates to surface patterns utilized on sanitary tissue products, and more particularly to sanitary tissue products comprising surface patterns, for example a 3D patterns, which can be formed for example by embossing the sanitary tissue product or fibrous structure employed therein with the surface pattern and / or molding the surface pattern into the sanitary tissue products and / or fibrous structures, such as by wet molding and dry molding onto a molding member comprising the surface pattern.BACKGROUND OF THE INVENTION[0002]Surface patterns having repeating design elements have been used on sanitary tissue products for many years. Most surface patterns have been created by embossing a pattern into a surface of the sanitary tissue product. Some have been created by wet forming, such as molding an embryonic fibrous structure onto a belt comprising a three-dimensional resin pattern that gets imparted to a surface of a fibrous structure a...
