Abstract
A method of making a paper product includes forming an aqueous cellulosic web on a structuring fabric in a papermaking machine, non-compactively dewatering the cellulosic web on the structuring fabric, and drying the cellulosic web to form the paper product. The portion of the structuring fabric on which the cellulosic web is formed has a planar volumetric index of at least about 26.
Claims15
A method of making a paper product, the method comprising:
- forming an aqueous cellulosic web on a structuring fabric in a papermaking machine;
- non-compactively dewatering the cellulosic web on the structuring fabric;
- and
- drying the cellulosic web to form the paper product,
- wherein the portion of the structuring fabric on which the cellulosic web is formed has a planar volumetric index of at least about 26.
A method of making a paper product, the method comprising:
- forming an aqueous cellulosic web on a structuring fabric in a papermaking machine;
- non-compactively dewatering the cellulosic web on the structuring fabric;
- and
- drying the cellulosic web to form the paper product,
- wherein a portion of the structuring fabric on which the cellulosic web is formed has a planar volumetric index of least than about 26 during (i) an initial period in which the cellulosic web is formed on the structuring fabric on the papermaking machine and (ii) after the structuring fabric is run for about 950,000 cycles of operation of the papermaking machine.
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 a planar volumetric index of at least about 26.
An absorbent cellulosic sheet made by a method that comprises:
- forming an aqueous cellulosic web on a structuring fabric in a papermaking machine;
- non-compactively dewatering the cellulosic web on the structuring fabric;
- and
- drying the cellulosic web to form the absorbent cellulosic sheet,
- wherein a portion of the structuring fabric on which the cellulosic web is formed has a planar volumetric index of at least about 26.
