Physical and Chemical Properties of Natural Fibers Extracted from Typha Australis Leaves

ABSTRACT

The objective of this study was to investigate the effect of the alkali solution (Potassium and Sodium hydroxide), retting process (time and temperature), and type of leaf (fresh and dry) on the physical and chemical properties of fibers extracted from the Typha leaves. Tensile properties, optical microscope, CIE lab, chemical composition, and Fourier transform spectra was used to determine the properties of fibers. The results showed that the extracted Typha fibers at low temperature were more yellow, a higher lignin to cellulose ratio and higher yield fibers than that extracted at high temperature.

从香蒲芦苇叶提取的天然纤维的物理和化学性质

本研究的目的是探讨碱溶液的（钾和氢氧化钠），脱胶过程（时间和温度），和叶的类型（干鲜）对香蒲叶子提取纤维的物理和化学性质的影响。拉伸性能、光学显微镜、CIE Lab，化学成分，和傅里叶变换光谱被用来测定纤维的性能。结果表明，提取的植物纤维在低温下更黄，更高的木质素纤维素纤维比和更高的产量比高温提取。结果表明，相比在高温提取，在低温下所提取的香蒲纤维更黄，有较高的木质素与纤维素比率，和更高的纤维产率。
