Method for preparing cellulosic fiber from camellia oleifera abel and prepared cellulosic fiber

The invention relates to a method for preparing cellulosic fibers from camellia oleifera shells and the prepared cellulosic fibers, and belongs to the technical field of nano material preparation. The method comprises the following steps: by taking camellia oleifera abel as a raw material, removing hemicellulose and impurities through acid washing and alkali washing, bleaching to obtain crude fibers, and hydrolyzing with sulfuric acid, centrifuging and dispersing to obtain cellulosic fibers. The cellulose fiber prepared by the invention has a high length-diameter ratio, and the length-diameter ratio is 50-100; the material has a network structure, is uniform in size distribution, and is beneficial to subsequent industrial utilization. In the preparation method, large instruments are eliminated, and waste utilization of the oil tea cattail is carried out by adopting a mode with lower energy consumption. 本申请涉及一种从油茶蒲中制备纤维素纤维的方法及所制备的纤维素纤维，属于纳米材料制备技术领域。该方法以油茶蒲为原料，经酸洗、碱洗去除半纤维和杂质，再经漂白得到粗纤维，再通过硫酸水解、离心、分散，得到纤维素纤维。本发明制
