Abstract
A method of making a pulp composition having improved strength characteristics is disclosed. The method includes mixing together a starch and fibrillated fibers to produce a starch/fibrillated fibers mixture, and mixing the starch/fibrillated fibers mixture into wood pulp fibers to produce the pulp composition.
Claims20
A method of making a pulp composition, the method comprising:
- mixing together a starch and fibrillated fibers to produce a starch/fibrillated fibers mixture;
- and
- mixing the starch/fibrillated fibers mixture into wood pulp fibers to produce the pulp composition.
A method of making a paper product, the method comprising:
- mixing together a starch and fibrillated fibers to produce a starch/fibrillated fibers mixture;
- mixing the starch/fibrillated fibers mixture into wood pulp fibers to produce a pulp composition;
- depositing the pulp composition onto a web to form a substrate;
- at least partially dewatering the substrate;
- and
- drying the substrate to form the paper product, wherein the paper product has an increased Breaking Length compared to a First Comparative Paper Product.

A paper product comprising:
- a starch in a first amount in the range of approximately 0.1 to 2.5 weight percent;
- fibrillated fibers in a second amount in the range of approximately 2 to 20 weight percent;
- and
- wood pulp fibers in a third amount in the range of approximately 83 to 97 weight percent,
- wherein the paper product has a lower amount of the starch compared to a Second Comparative Paper Product;
- and
- wherein the paper product maintains a Breaking Length within the range of approximately 10 percent compared to a Second Comparative Paper Product.
