Abstract:
1. A method for making plasticized fluff pulp, comprising: providing a cellulosic fluff pulp base fiber; providing a plasticizing formulation comprising a mixture of a primary plasticizing agent that is water soluble, non-ionic and non-polymeric and a secondary plasticizing agent; and applying the plasticizing formulation to the cellulosic fluff pulp base fiber to provide a plasticized fluff pulp, wherein the primary plasticizing agent prevents the cellulosic fluff pulp base fibers from forming bonds with other cellulosic fluff pulp fibers or superabsorbent polymer; wherein the plasticized fluff pulp has a final density that is lower than that of the non-plasticized cellulosic fluff pulp base fiber when the respective fluff pulp samples are defiberized, blended with superabsorbent polymer, highly compressed, and then released; and wherein the primary plasticizing agent is 1,2-cyclohexanedimethanol, 1,3-cyclohexanedimethanol, 1,4-cyclohexanedimethanol, or a mixture or combination thereof.
