Chemical activation and refining of southern pine kraft fibers for alteration of the morphology of cellulose fibers

摘要

Disclosed is a method for modulating the morphology of pulp fibers comprising the steps of: subjecting the fibers to a transitional metal ion-activated peroxide treatment carried out at a pH of from about 1 to about 7 at a temperature of from about 40 Deg. C to about 120 Deg. C for a time period of from about 10 minutes to about 600 minutes; and subjecting the treated fibers to a refining treatment. The transitional metal ion suitable for said method may be iron, copper (II), or cobalt (II).
