Abstract

In the present study, long staple lignocellulosic fibres were extracted from the arecanut leaf sheath, an agricultural biomass. The arecanut leaf sheath (ANLS) fibres have been extracted by alkali treatment. The important fibre properties such as fibre length, diameter, density, bundle strength, single fibre strength, moisture content and chemical composition are evaluated and compared with commonly available cellulosic fibres. Chemical nature and structure of ANLS fibre are determined using X-ray diffraction and FTIR techniques. The morphological structure and cross-section of the fibres were studied by scanning electron micrographs. The thermal properties of the fibre are characterized by thermo-gravimetric analysis. The potential of ANLS fibre to be used as a textile and reinforcing material is discussed in detail.

摘要

在本研究中，长短木质纤维素纤维是从槟榔叶鞘（一种农业生物质）中提取的。槟榔叶鞘 (ANLS) 纤维已通过碱处理提取。评估重要的纤维特性，如纤维长度、直径、密度、束强度、单纤维强度、水分含量和化学成分，并与常用的纤维素纤维进行比较。ANLS 纤维的化学性质和结构是使用 X 射线衍射和 FTIR 技术确定的。通过扫描电子显微照片研究了纤维的形态结构和横截面。纤维的热性能通过热重分析表征。详细讨论了 ANLS 纤维用作纺织品和增强材料的潜力。
