Abstract: An odor-inhibiting fiber having a cellulosic fiber and an odor-inhibiting formulation. The odor-inhibiting formulation may contain an odor-inhibiting agent, such as a biocide, an enzyme, a urease inhibitor. The odor-inhibiting formulation also may contain a liquid carrier such as a hydrophobic or hydrophilic organic liquid, or a mixture of a hydrophobic and hydrophilic organic liquid. The cellulosic fiber is impregnated with the odor-inhibiting formulation to produce fiber having odor-inhibiting characteristics. The resultant odor-inhibiting fiber is useful in making absorbent articles with odor-inhibiting characteristics. The fiber of the embodiments prevents odor by inhibiting bacteria growth and ammonia production, especially when used in an absorbent article such as a diaper or adult incontinence device.

Abstract: A method of making personal hygiene articles of high absorbency from cellulosic fiber pulp without chemical cross-linking of the cellulosic fibers is disclosed. The method comprises interposing a sublayer of mechanically fluffed alkali extracted cellulosic fiber pulp between a fluid permeable layer and a fluid impermeable layer.

Abstract: An improved absorbency material for absorbency applications comprised of a cellulosic fibrous material wherein said cellulosic fibrous material such as pulp is a cold alkali solution treated material at a treatment temperature of less than about 50° C.; a process for improving absorbency and other characteristics of said pulp.

Abstract: Systems and methods for purifying wood pulp by caustic-borate extraction. The systems and method include a method for recovering both the caustic and borate compounds from the resultant hemicaustic effluent, so that they may be recycled and re-used. Efficient recovery of these components is enabled by a nanofiltration system that has one or more alkali-resistant nanofiltration membranes.

Abstract: A plasticizing formulation for producing plasticized fluff pulp. The plasticizing formulation, which preferably is an aqueous solution, includes a primary plasticizing agent, and optionally a secondary plasticizing agent. Preferably, the primary plasticizing agent is 1,4-cyclohexanedimethanol, and the secondary plasticizing agent is triacetin. When the plasticizing formulation is applied to a cellulosic fluff pulp, a plasticized fluff pulp is produced. The resultant plasticized fluff pulp may have one or more of the following: reduced Kamas energy, Mullen strength, and fiber knot and nit contents, when compared to the base cellulosic fluff pulp fiber that is not plasticized.

Abstract: A liquid distribution mat that is a wet-laid mat of enhanced cellulosic fibers that are cellulosic fibers cross-linked in sheet form, as well as methods of making the liquid distribution mat. The liquid distribution mat has high vertical wicking properties and excellent structural integrity in both wet and dry states. The liquid distribution mat is suitable for use in an absorbent article. When used in an absorbent article such as a baby diaper, the liquid distribution mat rapidly acquires and transports bodily discharges from the point of insult to other regions of the absorbent article, thereby maximizing the utilization of the absorbent article.

Abstract: The present invention relates to cross-linked cellulosic fiber having improved absorbency characteristics when compared to conventional cross-linked fibers. The cross-linked cellulosic fiber is obtainable by reacting pulp in the sheet or fluff form with one or more reagents selected from organic molecule having acid and aldehyde functional groups “acid aldehydes.” The invention also relates to a method of producing the cross-linked fiber. The method includes heating the treated cellulosic fibers to promote intrafiber cross-linking. The cross-linked fibers are characterized by having an improved centrifuge retention capacity, fluid acquisition rate, resiliency, absorbent capacity, absorbency under load, and other absorbent properties. The inventive cross-linked fibers are useful in forming absorbent composites, and in particular absorbent cores for use in absorbent articles.

Abstract: A treatment composition for making acquisition fluff pulp in sheet form, having a cross-linking agent and an anti-hydrogen-bonding agent. The cross-linking agent may be a polycarboxylic acid, aldehyde, urea-based derivatives or a mixture thereof. The anti-hydrogen-bonding agent may be a silicon polymer terminated with at least one quaternary amine functional group. A method of making acquisition fluff pulp using the treatment composition involves treating a cellulosic base fiber with a treatment composition solution to impregnate the fiber with the treatment composition, and then drying and curing the impregnated fiber. The resultant acquisition fluff pulp may be utilized in an acquisition layer and/or an absorbent core of an absorbent article intended for body waste management.

Abstract: 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.
