In this research, a new method was developed for extracting fibre directly from the ramie. High-speed water treatment was found to be beneficial for the removal of husks. The proposed fibre extraction process included retting, first high-speed water treatment, oxidative degumming and second high-speed water treatment. The retting time and hydrogen peroxide concentration suitable for the removal of husks were found to be 7 days and 8 g/L, respectively. There was very little residual husk in the extracted sample. Scanning electron microscopy showed that most of the gums were removed. The fineness and tenacity values of the ramie fibre that was extracted using the proposed method were close to the values of the ramie fibre extracted by using the traditional process. As compared with the traditional process, the chemical agent consumption, boil time and labour intensity of the new extraction method were less.

从苎麻树皮中直接提取纤维

在这项研究中，开发了一种直接从苎麻中提取纤维的新方法。发现高速水处理有利于去除外壳。提议的纤维提取工艺包括沤制、第一次高速水处理、氧化脱胶和第二次高速水处理。发现适合去除壳的浸渍时间和过氧化氢浓度分别为 7 天和 8 g/L。提取的样品中几乎没有残留的外壳。扫描电子显微镜显示大部分牙龈被去除。使用该方法提取的苎麻纤维的细度和韧度值与使用传统工艺提取的苎麻纤维的值接近。与传统工艺相比，化学药剂消耗，
