Typha Leaves Fiber and Its Composites: A Review

ORCID Icon
Pages 4993-5007 | Published online: 19 Jan 2021
 

ABSTRACT

Typha is a semi-aquatic plant and an important member of wetlands around all over the world. This plant can be considered as a source of long leaf fibers. In this review, the works done in the last decade on the Typha leaf fiber extraction and its characteristics have been reviewed. Furthermore, the applications of the Typha fiber as a reinforcing material in the composite have been addressed. The Typha fiber properties are shown to be dependent on the extraction methods. The long cellulose fibers can be extracted from the Typha leaves using water retting and chemical treatments. The water-extracted Typha leaf fiber shows poor interlocking with the polymer matrix due to the high presence of waxy and non-cellulosic on the fiber surface. However, the alkali treatments of fibers could improve the composite properties. Typha fibers with low density (1.26 g/cm3), 47–67% cellulose content and 60–65% crystallinity, as well as 8.5–10% moisture regain and 25–40 cN/tex tensile strength, could be developed. In addition to these good properties, high thermal stability and low thermal conductivities (0.137 W/m. K) could lead to considering Typha fibers as a suitable alternative to expensive natural fibers and synthetic fibers in various polymer composites.

摘要

香蒲是一种半水生植物,是世界湿地的重要组成部分. 这种植物可以被认为是长叶纤维的来源. 本文综述了近十年来香蒲叶纤维提取及其特性的研究进展. 此外,还讨论了香蒲纤维作为增强材料在复合材料中的应用. 香蒲纤维的性质取决于提取方法. 通过水脱胶和化学处理,可以从香蒲叶中提取长纤维素纤维. 水提香蒲叶纤维表面蜡质和非纤维素含量高,与聚合物基体互锁性差. 而纤维的碱处理可以改善复合材料的性能. 香蒲纤维具有低密度(1.26g/cm3),纤维素含量47-67%,结晶度60-65%,回潮率8.5-10%,拉伸强度25-40cn/tex的特点. 除了这些优良的性能,高的热稳定性和低的热导率(0.137w/m.K)可能导致考虑香蒲纤维作为一个合适的替代品昂贵的天然纤维和合成纤维在各种聚合物复合材料.
