Estimating the term…
Paper sheets, such as tissue sheets useful for facial tissue, bath tissue and the like, are formed with a decorative pattern imparted to the tissue sheet by the forming fabric. The decorative pattern is incorporated into the forming fabric by a variety of means, such as stitching, silk screening, printing, weaving, or overlaying a fabric with a decorative pattern onto a conventional forming fabric. The presence of decoratively-shaped areas in the forming fabric, which are areas of relatively slow water drainage, cause corresponding areas in the resulting sheet to have a translucent appearance attributable to a relatively lower basis weight and/or different fiber composition. The decorative patterns are preferably formed in the outer or surface layer(s) of the paper sheet.
A tissue sheet having a distinct decorative pattern comprising curvilinear lines having a line width of from about 0.02 to about 2 millimeters cast into the sheet during its initial formation, said tissue sheet comprising long papermaking fibers and short papermaking fibers, wherein the decorative pattern is defined by areas having a greater average fiber length and a lower basis weight than the surrounding adjacent area of the tissue sheet.
A unitary tissue sheet comprising first and second layers, wherein said first layer contains a decorative pattern defined by areas of relatively low basis weight surrounded by a continuum of relatively high basis weight and wherein said second layer is of substantially uniform basis weight.
A tissue sheet of substantially uniform density having a distinct decorative pattern cast into the sheet during its initial formation, said tissue sheet comprising long papermaking fibers and short papermaking fibers, wherein the decorative pattern is defined by areas having a greater average fiber length and a lower basis weight than the surrounding adjacent area of the tissue sheet.
