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.
