ABSTRACT:
A method of reducing the amount of energy required to disintegrate comminution sheets formed from cellulose fibers without adversely affecting the absorbency, strength, or fluid transport properties of airfelts formed from the comminuted treated fibers. The method of the present invention includes the steps of preparing an aqueous slurry of cellulose fibers, adding an effective amount of a debonding agent such as aluminum or Kaolin clay to the cellulose slurry, and forming a comminution sheet from the fibers treated with the debonding agent. The debonding agent is added to the cellulose slurry in an amount effective to reduce the energy required to disintegrate comminution sheets formed from the fibers in the slurry by up to 50% of the amount of energy required to disintegrate comminution sheets formed from untreated pulp.
