纤维素纤维的开发始于 1 0 0多年前 ,不然现代纺织世界是难以想象的。目前 ,化学纤维生产持续增长 ,然而纤维素纤维的年产量虽已达到 2 1 0万ｔ/ａ(不包括香烟滤嘴醋酯丝束 ) ,但它在化纤总产量中只占 1 0 %。其原因是多种多样的 ,其中一个原因是经过详细调查 ,地球上水资源并 The development of cellulose fibers began more than 100 years ago, or the modern textile world is unimaginable. At present, the production of chemical fibers continues to grow. However, the annual output of cellulose fibers has reached 21 million t / a (excluding cigarette filter acetate tow), but it accounts for only 10% of the total chemical fiber output. One of the reasons for this is due to the fact that after careful investigation, the water resources on Earth and
