  • Patent number: 6203663
    Abstract: 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.

  • Patent number: 5702571
    Abstract: Tissue sheets, such as are useful for facial or bath tissue, can be embossed with a fine scale embossing pattern to increase bulk with 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) and can enable the tissue manufacturer to produce premium quality tissues having adequate softness, bulk and strength from conventional tissue basesheets without layering or throughdrying equipment. Depending on the starting basesheet material, tissues having a unique balance of properties can be produced, especially for conventional wet-pressed basesheets.
