【摘要】 本文论述了粘胶纤维的历史，特点和发展趋势。结合当前国际市场，分析了我国粘胶纤维行业面临的机遇、存在的问题及发展对策。提出要改变由于历史原因形成的粘胶纤维企业只重视作为终端产品的粘胶生产线的技术更新，而不重视提高作为半成品的浆粕生产水平的错误观念。指出只有不断采用新技术、新工艺、和新装备，提高化纤浆粕质量，才能最终达到提高粘胶纤维生产水平的目标。 在化纤浆粕生产过程中，对浆粕质量影响较大的主要是蒸煮、打浆和漂白工艺。本文对以云南松为原料采用预水解硫酸盐法蒸煮、常规“四合一”漂白(“CEHA”)的制浆工艺下，在打浆工序采用连续式的圆盘磨浆机代替传统的间歇式的荷兰式打浆机进行了研究。从理论上论述了打浆的作用，分析了采用圆盘磨浆机的可行性。并通过生产性实验与原工艺比较，探讨了适合的磨浆工艺参数的最佳值，探讨了采用圆盘磨浆机后对浆粕漂白、抄浆生产的影响，从制胶和粘胶可纺性方面对粘胶纤维生产的影响，从生产技术和经济指标两方面说明该技术是可行的。这项成果的应用有利于提高化纤浆粕和粘胶纤维的质量，此项技术对于粘胶纤维浆粕生产企业的技术改造和打浆工艺设计具有重要的积极意义。更多还原

【Abstract】 This thesis discourses upon the historical evolvement, character and developmental tendency of viscose fiber, and analyzes and demonstrates the opportunities, existing problems and developmental strategies with which Chinese industry of viscose fiber is confronted in the current cosmopolitan market. It also proposes that the wrong idea, which was formed under some historical factors and only attaches importance to technological transformation of the ultimate yield’ s production line, regardless of improving the production level of purified pulp as semifinished product , must be replaced with the new one that there is nothing to attain the goal of improving production level of viscose fiber but to adopt the new technologies, new processes and new equipments which aim at the quality of the purified pulp.In the process of producing the purified pulp, the main influencing factors to the quality of pulp are cooking&digast, beating pulp and bleaching. In the pulping processes of Yunnan pine which contained hydrolysis, sulfate pulping, cooking&digest, CEHA, the study of this thesis concentrated更多还原
