US Patent:

6340411, Jan 22, 2002

Filed:

Oct 7, 1998

Appl. No.:

09/167995

Inventors:

Michael R. Hansen - Seattle WA

Assignee:

Weyerhaeuser Company - Federal Way WA

International Classification:

D21H 1704

US Classification:

162173, 162179, 428497, 428532

Abstract:

A densifying agent is applied to fibers in order to improve the densification properties of the fibers. The fibers have hydrogen bonding functional groups. The densifying agent are denser than the fibers to which the densifying agent is applied. The densifying agent can be organic or inorganic. The improved densification properties are observed without the presence of particles bound to the fibers or in the presence of particles that are not bound to the fibers. Softening agents can also be applied to the fibers in order to soften the fibers and articles including such fibers. Softening agents may be selected from the group of densifying agents.

Filed:

Mar 4, 1998

Appl. No.:

09/035636

Inventors:

Michael R. Hansen - Seattle WA

Assignee:

Weyernaeuser Company - Federal Way WA

International Classification:

B32B 516

US Classification:

428403, 442417

Abstract:

A binder is applied to particles which are then combined with fibers to bind the particles to the fibers. The particles have functional sites for forming a hydrogen bond or a coordinate covalent bond. The fibers have hydrogen bonding functional sites. The binder comprises binder molecules, the binder molecules having at least one functional group that is capable of forming a hydrogen bond or a coordinate covalent bond with the particles, and at least one functional group that is capable of forming a hydrogen bond with the fibers. A substantial portion of the particles that are adhered to the fibers may be adhered in particulate form by hydrogen bonds or coordinate covalent bonds to the binder, and the binder in turn may be adhered to the fibers by hydrogen bonds. Fibers containing particles bound by this method are easily densified.

Appl. No.:

09/455080

Inventors:

Michael R. Hansen - Seattle WA
Donald D. Halabisky - Tacoma WA

Assignee:

Weyerhaeuser Company - Federal Way WA

International Classification:

B32B 502

US Classification:

428403, 4282961, 428402, 428408, 428913, 604365, 604367, 604368, 604375

Abstract:

The blood absorbence properties, e. g. , free swell blood absorbence capacity and after load blood absorbence capacity of superabsorbent materials is enhanced by combining the superabsorbent materials with enhancing agents which serve to enhance the blood absorbent properties thereof. The enhancing agents can be applied to the superabsorbent materials or they can be provided on a fibrous material to be combined with the superabsorbent materials. The enhancing agents are selected from materials that include functionalities that allow them to hydrogen bond to the superabsorbent material when the enhancing agent is applied directly thereto or combined with materials to which the enhancing agents have been applied.
