本世纪80年代以后,溶剂法生产再生纤维素纤维的研究取得了突破性的进展,并逐步走向工业化生产。本文简述了纤维素的溶解原理,介绍了NMMO/水系Tencel纤维和NaoH/水系新纤维的生产工艺及其工艺特点。
Since the 1980s, the research on regenerated cellulose fiber produced by solvent method has made breakthrough progress and gradually stepped into industrialized production. In this paper, the dissolution principle of cellulose is briefly introduced. The production technology and process characteristics of NMMO / water-based Tencel fiber and NaoH / water-based new fiber are introduced.
