Abstract
A cellulose pulp sheet is provided that is formed from never-dried kraft pulp and fibrillated fibers, such as lyocell. The pulp sheet provides several beneficial features as a result of both the use of fibrillated fibers and never-dried kraft pulp, particularly when the pulp sheet is used to form air-laid absorbent materials that include superabsorbent polymers.
