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 cellulose 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 cellulose fluff pulp fiber that is not plasticized.

Cette invention concerne une préparation de plastification pour pâte en flocons plastifiée. Cette préparation, qui se présente de préférence sous forme de solution aqueuse, comprend un élément plastifiant primaire et éventuellement un agent plastifiant secondaire. L'agent plastifiant primaire est de préférence un 1,4-cyclohexanediméthanol, et l'agent plastifiant secondaire de la triacétine. Lorsque la préparation de plastification est appliquée à une pâte cellulosique en flocons, on obtient une pâte en flocons plastifiée. Cette pâte en flocons plastifiée ainsi obtenue présente une ou plusieurs des caractéristiques suivantes réduites: énergie Kamas, robustesse Mullen et présence de noeuds et boucles, par comparaison avec la fibre de pâte en flocons non plastifiée.
