摘要 <p>METHOD OF PRODUCING HIGH YIELD CHEMIMECHANICAL PULPS An improved process for producing high yield chemimechanical pulps from wood or other lignocellulosic materials, such as chips, whereby the material is first sulfonated to at least about 85% of the maximum level of sulfonation, as defined, for such material without reducing the pulp yield to below 90% and subjecting the resulting sulfonated wood to mechanical defibration.</p>
