资源简介：
The invention relates to a process for producing a dissolving pulp from a cellulosic starting material using the kraft process， comprising the step of cooking the starting material with a cooking liquor. The process according to the invention characterized in that the starting material is exposed to a steam treatment prior to cooking and that the pulp obtained by cooking is subjected to cold caustic extraction (CCE) in the course of further processing.
本发明涉及一种采用硫酸盐法制浆（kraft process）工艺，以纤维素原料制备溶解浆（dissolving pulp）的方法，该方法包含采用蒸煮液对原料进行蒸煮的工序。本发明所述工艺的特征在于：在蒸煮工序前对原料实施蒸汽处理，且在后续加工过程中，将蒸煮所得纸浆进行冷碱抽提（Cold Caustic Extraction, CCE）。
