Abstract
A method for making stiffened cellulosic fiber in sheet form, and the resultant stiffened cellulosic fiber. The method of making the stiffened fibers involves impregnating a cellulosic base fiber in sheet form with a treatment composition solution, drying and curing the impregnated sheet, and thereafter adding water or an aqueous solution of odor removing agent to the cured sheet to produce a sheet of stiffened cellulosic fiber having a moisture content of at least about 6.0 weight %. When defiberized, the stiffened fiber has a low content of fines and knots and nits. The stiffened fiber also exhibits a low degree of yellowing and is substantially free of a burnt-like odor. The stiffened fiber may be used in an absorbent article, such as in a liquid acquisition layer or absorbent core of a baby diaper.
