  • Patent number: 11413368
    Abstract: Cellulosic pulp structures integrating unreacted quantities of an inorganic peroxide and a destabilizing acid, as binary components of an odor control system, absorbent articles incorporating such structures, and various methods of forming the same, are disclosed herein. The components are adapted to react in the presence of an aqueous fluid to produce hydrogen peroxide, thereby providing an antimicrobial and odor mitigating effect.

  • Patent number: 9212435
    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.

  • Publication number: 20030106163
    Abstract: A modified cellulosic fiber having superabsorbent properties is described. The modified fiber of the invention has a fibrous structure substantially identical to the cellulosic fiber from which it is derived. The modified fiber is a water-swellable, water-insoluble fiber that substantially retains its fibrous structure in its expanded, water-swelled state. The modified fiber is a sulfated and crosslinked cellulosic fiber having a liquid absorption capacity of at least about 4 g/g. In one embodiment, the modified fiber is an individual, crosslinked, sulfated cellulosic fiber. In another aspects, the invention provides a rollgood that includes the modified fiber, absorbent composites and articles that include the modified fiber, and methods for making the modified cellulosic fiber.
