Characterization of Cellulosic Leaf Fiber from the Typha Angustifolia Plant

ABSTRACT

Typha leaves are a rich source of fiber cables and these fibers can also be extracted by chemical retting method and these are easily bio-degradable, and eco-friendly. The main objective of present work is to assess the fiber characteristics such as FTIR, XRD, TGA, SEM, and single fiber tensile properties by varying fiber extraction parameters. In the retting process, IR peaks clearly shows that there was a removal nonfibrous material (NFM). Using X-ray diffraction technique 67.61% crystallinity with a crystallinity index of 0.521 was observed. Fiber tips of SEM images confirm that by increase in chemical concentration and treatment time, there was more removal of NFM and fibrillation found. For the fiber extraction mainly two treatment particulars were varied i.e. sodium hydroxide (10, 20, and 30 gpl) and time (3, 4, 5, and 6 h). Out of various retting conditions, at 20 gpl with 4 and 5 h treatment time shows an excellent tensile strength of single fiber, i.e. 125 Mpa and 179.82 Mpa and 30 gpl with 4 hrs and 5 h observed moderate strength, i.e. 106.03 Mpa and 122.69 Mpa respectively.

摘要

香蒲叶是纤维电缆的丰富来源这些纤维也可以通过化学脱胶法提取而且这些纤维易于生物降解和生态友好. 本工作的主要目的是通过改变纤维提取参数来评价纤维的FTIR、XRD、TGA、SEM和单纤维的拉伸性能. 在脱胶过程中红外光谱峰清楚地表明存在一种去除非纤维材料(NFM). 用X射线衍射技术观察到结晶度为67.61%结晶指数为0.521. 纤维尖端的SEM图像证实随着化学浓度和处理时间的增加NFM和原纤化的去除率增加. 纤维提取主要有两种处理方法即氢氧化钠(10、20和30 gpl)和时间(3、4、5和6小时). 在各种脱胶条件下20gpl处理4小时和5小时后单纤维的拉伸强度分别为125Mpa和179.82mpa30gpl的中等强度分别为106.03Mpa和122.69Mpa.
