Abstract:In viscose fiber production the dissolving pulp with proper quality is required, the kind of raw material and production process of the dissolving pulp are very important. The pulping mechanisms and the properties of the resultant dissolving pulps were analyzed when the processes of acid sulfite (AS) and pre-hydrolysis kraft (PHK) were applied. Other important parameters such as: chemical purity, molecular weight and molecular weight distribution, and reactivity of the dissolving pulps produced from the two processes were compared.
