Abstract:
A method of reducing the energy required to disintegrate a comminution sheet formed from cellulose fibers without substantially reducing the absorbency, strength or fluid transport properties of airfelts formed from the comminuted fibers, said method consisting essentially of the steps of:forming an aqueous slurry of cellulose fibers;adding a debonding agent to said cellulose slurry to coat the fibers in said slurry wherein the debonding agent is selected from the group consisting of alum, Kaolin clay, calcium carbonate, titanium dioxide and zinc oxide, said debonding agent being added in an amount effective to reduce the energy required to disintegrate a comminution sheet formed from said coated fibers by about 15% to about 50% from the amount of energy required to disintegrate comminution sheets formed from uncoated fibers; andforming said coated fibers into a comminution sheet.
