Abstract: Cellulose is an important renewable resource for chemical fiber industry. For regenerated cellulose fiber producers, it is an unavoidable responsibility to improve the sustainability of products and reduce the environment impact of the process. Based on eco-friendly concept, this article introduced some advanced technologies and products of regenerated cellulose fiber, including melt spinning cellulose-based fiber, nanofibrillated fibers and high value-added spunbond nonwovens with cuprammonium fiber, etc. Furthermore, the author also gave some suggestions on the sustainable development of domestic regenerated cellulose fiber industry, especially the viscose fiber industry.

Key words: eco-friendly; melt spinning regenerated cellulose fiber; viscose fiber; cuprammonium rayon
