Abstract
A method of providing papermaking fibers with durable curl comprising: a) introducing papermaking fiber into a rotatable drum adapted for operation at elevated pressure; b) rotating the drum containing the papermaking fiber while maintaining: i) the fiber in aqueous dispersion having a consistency of from about 5 to about 45 percent; ii) a temperature of above about 100° C.; the drum being configured such that the aqueous fiber dispersion contacts the rotating wall of the drum during rotation thereof and the mechanical action of the drum on the dispersion provides a durable curl to the papermaking fiber; removing the curled fiber from the rotatable drum wherein the temperature, time, consistency and energy input to the fiber are controlled such that fibers treated exhibit a curl elevation of at least 50 percent at 1 hour storage time.
