ABSTRACT:
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.
