PRODUCTION METHOD FOR DISSOLVING KRAFT PULP

摘要

　The purpose of the present invention is to provide a technique for appropriate management of the hydrolysis process during production of dissolving kraft pulp, and appropriate control of the dissolving kraft pulp production process. From the absorbance, at 260-300 nm, of the wastewater from the hydrolysis process during production of dissolving kraft pulp, the condition of the hydrolysis process can be appropriately ascertained, and the quality of the dissolving kraft pulp managed.
