Abstract

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.

Claims (7)

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.
