介绍了国内外用天然纤维素制备Lyocell薄膜和纤维的研究及生产现状。生产Lyocell的工艺是一种不经过化学反应的新工艺,几乎所有植物桔杆的纤维素都可作为生产原料。Lyocell产品是人类生产生活的新材料,可生物降解,解决了化学纤维难以自然降解的难题,可改变塑料薄膜造成的白色污染问题,其生产过程是清洁的,不污染环境。因此,人们称该工艺是“绿色生产工艺”、是环境友好工艺、是具有战略意义的可持续发展项目。 The research and production status of Lyocell film and fiber made from natural cellulose at home and abroad are introduced. Lyocell production process is a chemical reaction without a new process, almost all plant straw cellulose can be used as raw materials. Lyocell products are new materials used in human life and are biodegradable. They solve the difficult problem of chemical fiber degradation naturally and can change the white pollution caused by plastic film. The production process is clean and does not pollute the environment. Therefore, people call this process “green production process”, an environmentally friendly process and a strategically sustainable development project.
