In the present study, natural cellulose fibers were extracted from the Yucca leaves, and the effect of oxidative treatment on the properties of fibers was studied. The effect of bleaching parameters on the morphology and physical properties of a cellulose fiber called the Yucca fiber was investigated using Taguchi’s experimental design (L₂₇ orthogonal array). The whiteness index determined by reflectance spectroscopy increased by more than 38% because of the lignin removal. It was found that crystallinity, determined by X-ray diffraction (XRD) analysis, slightly increased by bleaching treatment due to the partial removal of non-cellulosic materials. Functional group analysis along with morphological analysis of the bleached fibers was conducted using Fourier transform infrared spectroscopy (FTIR) and Scanning electron microscopy (SEM) techniques, respectively. Thermal decomposition temperature obtained by thermogravimetric analysis (TGA) of the bleached fiber was found to increase about 40 °C. The results showed that the bleached fiber had good properties for use as a reinforcing material in polymer composites and the textile industry.

在本研究中，从丝兰叶中提取天然纤维素纤维，并研究了氧化处理对纤维性能的影响。使用Taguchi的实验设计研究了漂白参数对称为丝兰纤维的纤维素纤维的形态和物理性能的影响（L ₂₇正交数组）。由于木质素的去除，通过反射光谱法测定的白度指数增加了38％以上。发现通过X射线衍射（XRD）分析确定的结晶度由于非纤维素材料的部分去除而通过漂白处理而略有增加。分别使用傅立叶变换红外光谱（FTIR）和扫描电子显微镜（SEM）技术对漂白纤维进行了官能团分析和形态分析。发现通过漂白纤维的热重分析（TGA）获得的热分解温度升高约40℃。结果表明，该漂白纤维具有良好的性能，可用作聚合物复合材料和纺织工业的增强材料。
