20090260769 | METHOD FOR TREATING CELLULOSE-CONTAINING FIBERS OR PLANAR STRUCTURES CONTAINING CELLULOSE-CONTAINING FIBERS - Cellulosic substrates are treated with compound(s) containing at least two primary amino groups and compounds containing at least one β-ketocarbonyl group. The substrates exhibit good strength and hand properties. | 10-22-2009 |
20100018659 | GREASEPROOF PAPER - A greaseproof paper is provided for use in food processing and/or packaging of foods in which paper has been rendered oleophobic by treatment with a fluorine-containing polymer. The fluorine-containing polymer may be prepared by polymerizing a fluorine-containing monomer in the presence of a mercapto group-containing organopolysiloxane. The fluorine-containing polymer may be applied to paper by coating onto pre-formed paper, or by applying the polymer as a size during a papermaking process. | 01-28-2010 |
20100243187 | Method for Applying Chemical Additives to Pulp During the Pulp Processing and Products Made by Said Method - Pulp fibers can be treated with chemical additives with a minimal amount of unretained chemical additives present later in the process water. 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 chemical additive thereby forming a chemically treated dried fibrous web. The dried fibrous web contains chemically treated pulp fibers. The chemically treated pulp fibers retain from between about 10 to about 100 percent of the applied amount of the chemical additive when the chemically treated pulp fibers are redispersed in water. | 09-30-2010 |

20120285643 | WATER REPELLENT FIBER BOARDS - An acoustic building material and method for manufacture incorporates a homogenously dispersed reactive silicone to improve water repellency and physical properties. | 11-15-2012 |
20130269894 | Process for the production of paper - The present invention relates to a process for producing paper which comprises: providing an aqueous suspension comprising cellulosic fibres, adding to the suspension, after all points of high shear, a cationic polysaccharide; an inorganic polymer P1 being a cationic polyaluminium compound; and a polymer P2 being an anionic polymer; and, dewatering the obtained suspension to form paper. | 10-17-2013 |
20130277002 | PROCESS FOR THE PRODUCTION OF PAPER - The present invention relates to a process for producing paper which comprises:
| 10-24-2013 |
20150345080 | METHOD OF USING AN ANTI-SOILING AGENT COMPOSITION - [Object] To provide an anti-soiling agent compound that can sufficiently prevents adhesion of pitch to a dry part region. | 12-03-2015 |
