Abstract
Disclosed is a process for treating cellulosic fibers using high temperatures that is effective to result in modified cellulosic fibers that exhibit desired properties such as water retention values and wet curl values. The high temperature process is quite efficient and has been found to produce cellulosic fibers that are essentially uniformly treated. Also disclosed is a handsheet prepared from the treated cellulosic fibers for use in disposable absorbent products.
