Cellulose is naturally available most abundant biopolymer. Most of research has been focusing of extraction of cellulosic material from natural sources and waste sources. These waste sources are of two types: industrial waste and non-industrial wastes. However, industrial wastes are grabbing more interest as these could be available in enormous quantity, reduce environment pollution and also benefit commercially. To address this subject, in the present work, we have successfully converted the cellulosic wastes from viscose industry to high value materials such as Micro-crystalline cellulose (MCC) and Nanocrystalline cellulose (NCC). Furthermore, an important correlation between yield and crystallinity of produced NCC to molecular weight of cellulosic raw material was established. The above finding was characterized by different characterization techniques, such as Zeta sizer, Zeta potential and Scanning Electron Microscopy (SEM).

纤维素是天然可用的最丰富的生物聚合物。大多数研究都集中在从天然来源和废物来源中提取纤维素材料。这些废物来源有两种类型：工业废物和非工业废物。然而，工业废物引起了更多的兴趣，因为这些废物可以大量获得，减少环境污染并在商业上受益。为了解决这个问题，在目前的工作中，我们成功地将粘胶工业的纤维素废物转化为高价值材料，如微晶纤维素 (MCC) 和纳米晶纤维素 (NCC)。此外，建立了所生产的 NCC 的产率和结晶度与纤维素原料分子量之间的重要相关性。
