20090283229 | FUNCTIONALIZING CELLULOSIC AND LIGNOCELLULOSIC MATERIALS - Irradiated lignocellulosic or cellulosic materials are provided which contain carboxylic acid groups and/or other functional groups not present in a naturally occurring cellulosic or lignocellulosic material from which the irradiated material was obtained | 11-19-2009 |
20090321025 | PULP REACTIVITY ENHANCEMENT - This invention relates to pulp reactivity enhancement. In particular, the invention relates to a method of producing an alkali cellulose which includes steps of providing a pulp and subjecting the pulp to an alkaline treatment to produce the alkali cellulose in the presence of a spacer capable of entering the holes in the interfibrillar spaces of the cellulose fibres. The spacer enters the holes in the interfibrillar spaces of the cellulose fibres, particularly those created by the removal of hemi-cellulose, reducing the tendency for collapse to occur, for example during the subsequent pressing step. Examples of suitable spacers are polyethylene glycols, polyvinyl alcohols and polyacrylates. | 12-31-2009 |
20090321026 | PAPER PRODUCTS AND METHODS AND SYSTEMS FOR MANUFACTURING SUCH PRODUCTS - Methods of producing cellulosic or lignocellulosic materials for use in papermaking include treating a cellulosic or lignocellulosic dry feedstock having a first average molecular weight with ionizing radiation, and controlling the dose of ionizing radiation such that the average molecular weight of the feedstock is reduced to a predetermined level. A method of producing an irradiated paper product includes treating a paper product including a first carbohydrate-containing material having a first molecular weight with ionizing radiation, and controlling the dose of ionizing radiation so as to provide an irradiated paper product with a second carbohydrate-containing material having a second molecular weight higher than the first molecular weight. Pulp and paper products are produced. | 12-31-2009 |
20100006245 | PULP AND PROCESS FOR PULPING - The invention relates to a new pulp, which is derived from lignocellulosic material subjected to agitation in an aqueous tetra-alkylammonium salt solution under microwave irradiation. The invention relates also to a process for pulping lignocellulosic material and to a process for softening lignocellulosic material. The treated material is preferably wood, softwood or hardwood. | 01-14-2010 |
