Method of preparing a treated article and treated article formed therefrom |
摘要 |
A method of preparing a treated article comprises the step of providing a slurry comprising fibers. The method further comprises the step of combining the slurry and a first fluorinated composition to form a mixture. In addition, the method comprises the step of forming at least one sheet from the mixture. Finally, the method comprises the step of applying a second fluorinated composition on at least one surface of the at least one sheet to prepare the treated article. |

1. A method of preparing a treated article, said method comprising the steps of:
providing a slurry comprising fibers; combining the slurry and a first fluorinated composition to form a mixture; forming at least one sheet from the mixture; and applying a second fluorinated composition on at least one surface of the at least one sheet to prepare the treated article; wherein the first fluorinated composition is further defined as a cationic fluorinated composition comprising a fluorinated polymer and wherein the second fluorinated composition is further defined as a cationic fluorinated composition comprising a fluorinated polymer, and wherein a ratio of the weight percent of the fluorinated polymer in the first fluorinated composition to the weight percent of the fluorinated polymer in the second fluorinated composition is from 1:4 to 1:7. |
