Abstract

Official abstract text for this publication.

A papermaking machine for making a paper product using a through air drying process. A headbox supplies an aqueous furnish. A structuring fabric has a surface with a contact area and (i) receives the furnish from the headbox on the surface to thereby form a cellulosic web from the furnish and (ii) non-compactively dewaters the cellulosic web. At least one through air drier dries the cellulosic web on the structuring fabric. A portion of the structuring fabric on which the cellulosic web is formed has an adjusted planar volumetric index of at least about 27.

First claim

Opening claim text (preview).

We claim: 1. A papermaking machine for making a paper product using a through air drying process, the papermaking machine comprising: a headbox for supplying an aqueous furnish; a structuring fabric having a surface with a contact area, the structuring fabric being configured (i) to receive the furnish from the headbox on the surface to thereby form a cellulosic web from the furnish and (ii) to non-compactively dewater the cellulosic web; and at least one through air drier for drying the cellulosic web on the structuring fabric, wherein a portion of the structuring fabric on which the cellulosic web is formed has an adjusted planar volumetric index of at least about 27. 2. The papermaking machine according to claim 1 , wherein the adjusted planar volumetric index is about 27 to about 31.5. 3. The papermaking machine according to claim 1 , wherein the contact area of the structuring fabric is entirely formed by knuckles on warp yarns of the structuring fabric.
