我国4种锦葵科植物韧皮纤维结构特征与物理性能研究
Study on Structural Characteristics and Physical Properties of Four Types of Malvaceae Phloem Fibers in China
摘要
Abstract
This study investigated the fiber cell wall structure and mechanical properties of four wild Malvaceae phloem fibers from China:Sterculia lanceolata Cav.,Sterculia pexa Pierre,Abelmoschus manihot var.pungens,and Triumfetta cana Blume.The results showed that all four Malvaceae phloem fibers exhibited elongated morphology with distinct transverse striations.The fiber surfaces were rough,and mi-crofibrils displayed longitudinal corrugated fold structure.The density ranged from 1.54 to 1.63 g/cm³,crystallinity ranged from 75.26%to 79.27%,and the S2 layer microfibril angle ranged from 8° to 23°.Notably,Abelmoschus manihot var.pungens displayed a significantly higher zero-span tensile strength of 113 N/cm compared to the other three phloem fibers(23.4~54.9 N/cm),with its strength showing a clear positive correlation with the thickness of the fiber cell wall.关键词
