A layered paper and method of making it, which paper is characterized by having a soft, relatively untextured smooth velutinous surface defined by a multiplicity of relatively flaccid papermaking fibers having unbonded free end portions of substantial length, and which surface is subjectively discernible by humans as being extremely soft and smooth. Exemplary embodiments include tissue paper, and tissue paper products comprising one or more plies of such paper. The method includes wet laying a layered web which has a relatively low bond surface layer comprising at least about 60% relatively short papermaking fibers, drying the web without imparting substantial texture thereto, breaking sufficient papermaking bonds in the surface layer to generate a velutinous surface having an FFE-Index of at least about 60 and preferably at least about 90, and calendering the dried web as required to provide said surface layer with an HTR-Texture of about 1.0 or less, and more preferably about 0.7 or less, and most preferably about 0.1 or less.
A tissue paper sheet having a substantially flat velutinous top surface, said sheet comprising a first layer comprising papermaking fibers and a second layer comprising substrate means for supporting said first layer and for providing said product with sufficient tensile strength for its intended purpose, said first layer comprising a primary filamentary constituent of about 60% or more by weight of relatively short papermaking fibers having average lengths of from about 0.25 mm to about 1.50 mm, said velutinous top surface being the outwardly facing surface of said first layer which surface is defined by substantially unbonded free end portions of a multiplicity of said short fibers, said sheet having an average top surface human-tactile-response texture (HTR-Texture) of about 1.0 or less, and said velutinous top surface having an average free-fiber-end index (FFE-Index) of at least about sixty (60).
A two-ply sheet type tissue paper product having a substantially flat velutinous top surface, said product comprising a first ply of tissue paper and a second ply of tissue paper in juxtaposed relation, said first ply being a two-layer tissue paper sheet comprising a first layer and a second layer, said first layer comprising a primary filamentary constituent of about 60% or more by weight of relatively short papermaking fibers having average lengths of from about 0.25 mm to about 1.5 mm, said velutinous top surface being the outwardly facing surface of said first layer which surface is defined by substantially unbonded free end portions of a multiplicity of said short fibers, said sheet having an average HTR-Texture of about 1.0 or less, and said velutinous surface having an average FFE-Index of at least about sixty (60).
A method of making a multi-layer wet-laid tissue paper sheet having a substantially flat and smooth velutinous top surface which velutinous top surface comprises a primary filamentary constituent of about 60% or more by weight of relatively short papermaking fibers having average lengths of about 1.5 mm or less, and which velutinous top surface is characterized by an average free-fiber-end index (FFE-Index) of about 60 or greater and an average humantactile-response texture (HTR-Texture) of about 1.0 or less, said method comprising the steps of:
A method of making a 3-layer wet-laid tissue paper sheet having a substantially flat and smooth velutinous top surface and a substantially textured bottom surface, said velutinous top surface comprising a primary filamentary constituent of about 60% or more by weight of relatively short papermaking fibers having average lengths of about 1.5 mm or less and which velutinous top surface is characterized by an average free-fiber-end index (FFE-Index) of about 60 or greater and an average human-tactile-response texture (HTR-Texture) of about 1.0 or less, said method comprising the steps of:
