摘要

本研究的目的是调査门东草的形态，结构，和门东纤维的化学性质，从门东草中提取的原料和处理过的纤维的形成碱包含化学的内容和功能组和评价门冬纤维与其它天然纤维的强度和性能比较。这些研究探讨纤维包括纤维组成和官能团的红外光谱的化学性质，纤维的力学性能，并用SEM和XRD对纤维的结构和形态分析。结果表明，门东纤维的化学含量分别为72.14%纤维素，20.2%的半纤维素，3.44%的木质素，4.2%的提取物，和4.2%-5.2%的水分。纤维的力学性能表现拉伸强度452兆帕，和模量17 GPa。门东纤维的结构性质如结晶度，结晶性指标，微纤丝角，结晶大小分别为70.17%和58.6%，22.9°和14.3nm。该纤维具有与其他天然纤维相比的竞争优势，可以进一步发展成为一个潜在的增强聚合物基复合材料。%This study was to investigate the morphology, structure, and chemical properties of the Mendong fibers extracted from Mendong grass (Fimbristylis globulosa) in the form of raw and treated fiber by alkali-included chemical content and functional group and to evaluate the strength and properties of Mendong fibers compared with other natural fibers. These studies explore the chemical properties of the fiber including fiber composition and functional group by FTIR, mechanical properties of fiber, and the structural and morphological analysis of the fiber using SEM and XRD. The results showed that the chemical contents of Mendong fibers were 72.14% cellulose, 20.2% bemicellulose, 3.44% lignin, 4.2% extractive, and moisture of 4.2%-5.2%. Mechanical properties of the fiber were a strong character with tensile strength of 452 MPa, and modulus of 17 GPa. The structural properties of Mendong fiber such as crystallinity, crystalline index, microfibril angle, and crystalline size were 70.17% and 58.6%， 22.9° and 14.3 nm， respectively. This fiber has competitive advantages compared with other natural fibers and can be developed further as a potential reinforcement of polymer matrix composites.
