Abstract

A process for bleaching high bulk cellulosic fiber and producing a durab le elevated curl index includes: (a) concurrently bleaching, heat treating and convolving cellulosic fiber pulp at elevated temperature and pressure at high consisten cy generally under conditions selected so as to preclude substantial fibrillati on and attendant paper strength and fiber bonding development; and (b) recovering t he pulp wherein the length weighted curl index of the treated fiber is at least abou t 20% higher than the length weighted curl index of the fiber prior to the heat treatment and convolving thereof. Preferably, the curl imparted to the fiber persists upon treatment for 30 minutes in a laboratory disintegrator at 3000 rpm at 1% consistency a t a temperature of 125.degree.F. Moreover, the curl may be imparted to the fiber in a disk refiner at very short residence times, on the order of several seconds or less. In general, the process is carried out in the presence of saturated steam at a pressure of from about 5 to about 150 psig.
