The deacidifying agent migrates over time to the paper article in an amount sufficient to retard the deterioration rate of the paper. The method can further include placing in the polymer film enclosure a carrier material having a second reservoir of deacidifying agent. An article for retarding the deterioration rate of acidic paper is also disclosed. The article includes a polymer film enclosure having a reservoir of deacidifying agent. The polymer film enclosure is capable of enclosing an acidic paper article. The deacidifying agent is capable of migrating over time to the acidic paper article enclosed therein in an amount sufficient to retard the deterioration rate of the paper. The article can further include a carrier material having a reservoir of deacidifying agent.Type: ApplicationFiled: March 2, 2001Publication date: December 26, 2002Inventor: Ronald E. Johnson

Patent number: 6494989Abstract: Absorbent wetlaid paper containing at least 1% by weight, calculated on the dry weight of the paper, of an absorbent polymeric material having a thermo-reversible liquid uptake capacity, which has a cloud point, Cp, in water within the temperature interval 30-60° C., preferably 35-55° C., at which the polymer has a substantially higher liquid uptake capacity at temperatures below said cloud point as compared to at temperatures above the cloud point. The thermo-reversible polymer will then be inactive during the papermaking process and be activated to its swelling and absorbent form when it is brought into contact with a liquid, the temperature of which is below the cloud point, Cp, of the polymer.Type: GrantFiled: August 16, 2001Date of Patent: December 17, 2002Assignee: SCA Hygiene Products ABInventors: Jeanette Annergren, Holger Hollmark, Ulrika Strandlund

Patent number: 6488813Abstract: Paper with increased wet strength is produced by adding to the stock a water soluble blocked urethane prepolymer having a plurality of blocked isocyanate groups and hydrophilic groups. The blocking agent is a phenol compound having an electron-attracting group at the ortho- or para-position. The blocked urethane prepolymer is capable of unblocking under such conditions that encounter in the drying part of conventional paper making machines.Type: GrantFiled: July 31, 2001Date of Patent: December 3, 2002Assignee: Dai-Ichi Kogyo Seiyaku Co., Ltd.Inventors: Takeshi Doi, Naofumi Saiuchi, Masahiro Kouchi

Publication number: 20020139500Abstract: Pulp fibers can be treated with water insoluble chemical additives resulting in a minimal amount of unretained water insoluble chemical additives present after redispersing the treated pulp fibers in the process water. One embodiment of the present invention is a method for preparing chemically treated pulp fiber. A fiber slurry is created comprising process water and pulp fibers. The fiber slurry is transported to a web-forming apparatus of a pulp sheet machine thereby forming a wet fibrous web. The wet fibrous web is dried to a predetermined consistency thereby forming a dried fibrous web. The dried fibrous web is treated with a water insoluble chemical additive thereby forming a chemically treated dried fibrous web containing chemically treated pulp fibers.Type: ApplicationFiled: March 7, 2001Publication date: October 3, 2002Inventors: Troy Michael Runge, Louise Cynthia Ellis Coe, Mike Thomas Goulet, Sheng-Hsin Hu
