    摘要： The invention provides a method for preparing cross-linked cellulosic fibers. A sheet of mercerized cellulosic fibers with a purity of at least 95% is treated with a solution containing a carboxylic acid cross-linking agent. The treated cellulosic fibrous material is dried and cured in sheet form to promote intrafiber cross-linking. Cross-linked fiber products produced are economic and possess good porosity, bulking characteristics, wet resiliency, absorption characteristics, low fines, low nits and low knots. The invention also includes blended cellulose compositions comprising a minor proportion of cross-linked mercerized cellulosic fibers and a major proportion of other cellulosic fibers. The invention further provides individualized, chemically cross-linked mercerized cellulosic fibers of high purity.

    摘要： The present invention relates to a method for loading a chemical compound within the fibers of a fibrous material and to the fibrous materials produced by the method. In the method, a fibrous cellulose material is provided which consists of a plurality of elongated fibers having a fiber wall surrounding a hollow interior. The fibrous material has a moisture content such that the level of water ranges from 40-95% of the weight of the fibrous material and the water is positioned substantially within the hollow interior of the fibers and within the fiber walls of the fibers. A chemical is added to the fibrous material in a manner such that the chemical is disposed in the water present in the fibrous material. The fibrous material is then contacted with a gas which is reactive with the chemical to form a water insoluble chemical compound. The method provides a fibrous material having a chemical compound loaded within the hollow interiors and within the fiber walls of the plurality of fibers.

    摘要： A process for making a stiffened and rigid paper includes preparing a pulp slurry consisting essentially of water, a cellulosic pulp, a crosslinker, and a starch, and optionally a binder; draining the liquid from the pulp slurry to form a web; and drying the web. Alternatively, a process for making a stiffened and rigid paper includes the step of adding at least one crosslinker at one or more locations, such as at the wet-end, dry-end, or at both ends of the papermaking process. Suitable crosslinkers include a glyoxal-containing crosslinker, a gluteraldehyde, a polyfunctional aziridine, a zirconium-containing crosslinker, a titanium-containing crosslinker, and an epichlorohydrin, and mixtures thereof. When a binder is employed, it can be added either in the dry or wet form. Provided is a neutral or alkaline process to produce a paper product having the improved mechanical properties of a laminated product in the Z-direction, without a lamination step.

    摘要： The invention relates to a method for producing a sheet of paper (6) comprising paper fibres and calcium carbonate mainly in the form of calcite crystals linked directly to the paper fibres. The inventive method is characterised in that it comprises the following steps:—(i) an aqueous composition comprising calcium bicarbonates (5) and/or hydrated and/or dissolved carbon dioxide (3) and (ii) an aqueous composition comprising calcium hydroxide (4) are mixed in an aqueous medium in such a way as to precipitate the calcium carbonate in the form of vaterite crystals;—paper fibres (2, 2′) are immediately added;—the vaterite crystals are left to transform into calcite crystals on contact with the fibres;—said mixture containing the calcite crystals which are fixed to the fibres is subsequently sent on the conveying wire of the papermaking machine (M) for drainage and so that the sheet of paper can be formed;—the sheet of paper (6) thus obtained is treated, if necessary, and dried.
