Abstract
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.
Claims22
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 an anionic fluorinated composition and wherein the second fluorinated composition is further defined as a cationic fluorinated composition.
A method of preparing a treated cellulosic article, said method comprising the steps of:
- providing a slurry comprising cellulosic fibers;
- combining the slurry and an anionic fluorinated composition to form a mixture;
- forming at least one sheet from the mixture;
- and
- applying a cationic fluorinated composition on at least one surface of the at least one sheet to prepare the treated cellulosic article.
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 an anionic fluorinated composition comprising from 0.1 to 0.7 wt. % of a first fluorinated copolymer, and wherein the second fluorinated composition is further defined as a cationic fluorinated composition comprising from 0.1 to 0.7 wt. % of a second fluorinated copolymer.
