20080264587 | Reducing the Water and Water Vapour Absorbence and Enhancing the Dimensional Stability of Paper and Paper Products and Use of Coated Paper Products - The invention relates to a method for reducing the absorption of water and water vapor and for increasing the dimensional stability of paper and paper products by treatment with an aqueous solution and/or dispersion of at least one reactive material which reacts with itself and/or cellulose fibers with crosslinking, cellulose fibers or a paper product obtained therefrom by drainage on a wire being compressed, the compressed paper product then being brought into contact with an aqueous solution and/or dispersion of the reactive material, the compression being eliminated with further action of the aqueous solution and/or dispersion and the paper product being dried and crosslinked, and to the use of the coated paper products thus obtainable and/or of the coated cellulose fibers which can be produced therefrom by defibrating as an additive to thermoplastics and as an additive to heat-curable plastics. | 10-30-2008 |
20090022775 | POLYMER BACKBONE FOR PRODUCING ARTIFICIAL TISSUE - The invention relates to polymer scaffolds suitable for producing artificial tissues, in particular polysaccharide scaffolds, to processes for their preparation, to their use for producing artificial tissues, and to artificial tissues produced on the basis of such polymer scaffolds. | 01-22-2009 |
20090272505 | METHOD FOR FINISHING PAPER AND PAPER PRODUCTS - Process for finishing paper and paper products by treating the surface of paper or paper products with at least one finishing agent, at least one finishing agent being applied in the form of a pattern on the top and/or bottom of paper or paper products, and the papers and paper products obtainable by the process. | 11-05-2009 |
20100000693 | METHOD FOR PRODUCING A MULTI LAYER FIBER WEB FROM CELLULOSE FIBERS - A process for the production of a multilayer fiber web from cellulose fibers by separately feeding at least two different fiber suspensions and water into a multilayer headbox, in which they are separated by separating elements from one another and from water and, after leaving the nozzle mouth of the headbox, reach an apparatus on which a web is formed, the water being transported in such a way that, after emerging from the nozzle mouth, it reaches the web-forming apparatus in the form of a layer between two layers of fiber suspensions and thus counteracts mixing of the different fiber suspensions, wherein, for improving the retention, drainage and formation, at least one retention aid and/or at least one drainage aid are metered into the fiber suspensions and/or into the water fed in. | 01-07-2010 |
20100034858 | BIOCIDAL COATINGS - Biocidal multilayered system, characterized in that it comprises at least the following layers: —an anionic or cationic carrier, preferably cellulose as anionic carrier, —on this carrier alternating polymeric cationic and anionic layers starting with a layer having a charge opposite to that of the carrier, —wherein at least one layer is hydrophobically modified. | 02-11-2010 |
20140209836 | AQUEOUS DISPERSIONS OF POLYMERS WHICH COMPRISE A FLUORESCENT DYE, PROCESS FOR THEIR PRODUCTION AND THEIR USE FOR MARKING MATERIALS - Aqueous dispersions of polymers which are obtainable by free radical suspension polymerization of ethylenically unsaturated monomers in an oil-in-water emulsion whose disperse phase comprises at least one fluorescent dye dissolved in at least one ethylenically unsaturated monomer and has an average particle diameter of at least 1 μm, in the presence of at least one surface-active compound and at least 0.5% per weight, based on the monomers, of at least one hydrophobic, nonpolymerizable organic compound, of a hydrophobic polymer of at least one C | 07-31-2014 |
