Development and Characterization of Pineapple Fibre Nonwovens for Thermal and Sound Insulation Applications

ABSTRACT

Due to the environmental damage caused by synthetic materials, natural fibers are gaining importance day by day. Apart from the conventional sources of fibers, researchers are interested in some underexploited fibers, which are having high potential applications in textiles. Pineapple leaf fiber (PALF) is an agro residue, extracted by scratching of pineapple leaves. In this study, pineapple fibers were extracted from pineapple leaves by raspador technique. The physical, morphological, and thermal properties of pineapple fibers were characterized. The nonwovens were developed from 100% pineapple fibers and also by blending low melting point polyester with pineapple fibers by needle punching technique. The developed nonwovens were characterized for sound and thermal insulation applications. It was found that nonwovens made by blending PALF with low melt PET had better thermal and sound insulation characteristics compared to the nonwovens made from 100% PALF fibers.

摘要

本工作的目的是通过TEMPO方法获得纤维素纳米纤维.然而，要达到这一目的，需要按照这一顺序应用漂白、除颤和TEMPO方法，即槽形Curaua纤维（CF）.TEM张显微照片证明，经过漂白和除颤处理后，获得了纤维素纳米纤维（CNF）.扫描电镜照片表明，CF漂白工艺是有效的.傅立叶变换红外光谱（FTIR）分析表明，处理后样品的氧化产物具有特征峰，表明对纤维素有效.结果表明，TEMPO方法提高了结晶度，降低了聚合度.根据我们的研究结果，纳米晶须的使用可能适用于多种应用，例如生产纳米复合材料.
