Abstract
A method of modifying a two-dimensional, flat fiber morphology of a never-been-dried wood pulp into a three-dimensional twisted fiber morphology without the aid of a chemical cross-linker. The method includes the steps of treating a never-been-dried wood pulp fiber slurry with a drying aid and thermally drying the wood pulp fiber slurry. The method may alternatively, or additionally, include the steps of spray drying a wood pulp fiber slurry and/or a slurry of a hydrophilic material, and flash drying the spray dried wood pulp fiber slurry and/or slurry of hydrophilic material.
