Definitions

  • the present invention relates to cellulosic fibrous web, particularly a cellulosic fibrous web having an embossed pattern.
  • the embossing pattern provides an aesthetic appearance and bulk for the cellulosic fibrous web.
  • Cellulosic fibrous web such as tissue products
  • Toilet tissue, paper towels, and facial tissue are examples of cellulosic fibrous web used throughout home and industry.
  • a cellulosic fibrous web which remains unaltered from the base sheet has been long accepted by consumers, there is a need for cellulosic fibrous web having an aesthetic appearance.
  • the aesthetic appearance of the cellulosic fibrous web gives consumers the impression of high quality products. It is also desirable to impart the cellulosic fibrous web bulk. The property of bulk is desirable for high quality products because it is associated with softness and absorbency from consumer standpoint.
  • embossing patterns are common to impart aesthetic appearance and bulk to the cellulosic fibrous web.
  • Considerable efforts have been directed to embossing cellulosic fibrous web.
  • U.S. Patent 5,562,805 issued to Kamps et al. on October 8, 1996 discloses a method for making soft high bulk tissue.
  • the tissue is embossed with a fine scale embossing pattern to increase bulk and a minimal loss in strength.
  • the fine scale embossing pattern contains at least about 15 discrete intermeshing embossing elements per square centimeter (100 per square inch).
  • US. Patent 5,300,347 issued to Underhill et al. on April 5, 1994 discloses an embossed facial tissue.
  • the uniformly embossed facial tissue has a continuous or closely- spaced discontinuous embossing pattern.
  • the lines of embossing pattern leave the unembossed pillow surrounded by the lines of embossing relatively bulky.
  • the tissue has from about 1 to about 40 distinct individual unembossed areas per square inch of tissue.
  • U.S. Patent 4,759,967 issued to Bauernfeind on July 26, 1988 discloses an embossing process and product. A majority, and preferably substantially all, of the background embossments have major and minor axis. The major axis is substantially aligned in the CD of the sheet. It also discloses the background embossing pattern which essentially covers the sheet and an additional intermittent design pattern. The additional intermittent design pattern is formed by unembossed neutral plane.
  • One approach to achieve it is arranging the embossments to form a desired pattern, e.g., by remaining a predetermined area of the cellulosic fibrous web unembossed, thereby forming a design pattern by unembossed plane. Remaining many portions of the cellulosic fibrous web unembossed may impart more aesthetic appearance for the web.
  • too many unembossed areas on the cellulosic fibrous web disrupt the nesting of the sheets when wound in a roll or piled in a box. This causes product issues such as ridging and/or wrinkles on the surface of the roll product or the product filled in the box.
  • the present invention relates to a cellulosic fibrous web having an embossing pattern.
  • the embossing pattern comprises a repeating pattern.
  • One repeating pattern comprises a plurality of discrete, distinctive lands and a background matrix formed by a plurality of discrete elements.
  • the repeating pattern is provided by embossing the cellulosic fibrous web.
  • the background matrix has a density of from 40 to 90 of the discrete elements per square inch.
  • the discrete, distinctive land is defined by being substantially surrounded by the discrete elements of the background matrix.
  • One discrete, distinctive land corresponds to the size eliminating from 4 to 90 of the discrete elements from the background matrix.
  • the total area of the discrete, distinctive lands in one repeating pattern occupies from 3 % to 35 % of the area of one repeating pattern.
  • FIG. 1 is a plan view of a cellulosic fibrous web having an embossing pattern
  • FIG. 2 is a cross-sectional view of a cellulosic fibrous web shown in FIG. 1 taken along a II-II line;

  • the tissue 12 extends in two directions; machine direction MD and cross machine direction CD.
  • machine direction designated MD
  • cross machine direction designated CD
  • machine direction is the direction perpendicular to the machine direction in the X-Y plane.
  • the embossing pattern 10 has two or more of a repeating pattern 14 repeating in the machine direction MD.
  • One repeating pattern 14 comprises a plurality of discrete, distinctive lands 16 and a background matrix 18.
  • One repeating pattern in MD can be determined by comparing contiguous patterns having the same length in MD. When the contiguous patterns having the same length in MD are the same along the MD of the product, the pattern is a repeating pattern.

Abstract

L'invention concerne un voile fibreux cellulosique pourvu d'un motif de gaufrage comprenant un motif répétitif. Un motif répétitif comprend une pluralité de plats distincts et séparés et une matrice de fond pourvue d'une pluralité d'éléments séparés. Le motif répétitif est produit par gaufrage du voile fibreux cellulosique. La matrice de fond présente une densité variant entre 40 et 90 éléments séparés par pouce carré. Le plat distinct et séparé est délimité par les éléments séparés de la matrice de fond qui l'entourent en partie. La surface d'un plat distinct et séparé correspond à l'élimination de 4 à 90 éléments séparés de la matrice de fond. La surface totale des plats distincts et séparés dans un motif répétitif occupe entre 3 et 35 % de la surface d'un motif répétitif.
