Evaluation of Moisture Content, Chemical, and Functional Groups of Paederia Foetida Fibers: Effects of Time Soaking in Chemical Solutions

Abstract

Due to their abundance and environmental friendliness, Paederia foetida stem fiber (PFs) are an interesting material to develop as a substitute for glass fiber. The goal of this research is to provide a thorough understanding of the physical, chemical, and functional properties of PFs. The PFs were treated for 1 h, 2 h, and 4 h with 95% ethanol and 25% NaClO 2 , respectively, before being rinsed and dried in a 105 °C oven. The density, moisture content, functional group (FTIR), and chemical composition of PFs were all tested to determine their properties. The results showed that PFs raw has moisture content and density of 12 ± 0.78% and 1.02 ± 0.012 g/cm 3 , respectively. After submerged in chemical solution for 4 h, the PFs had the lowest moisture content and density, but cellulose content to increased (67%), compare with other fibers; due to lignin and hemicellulose reduction. The functional groups of the PFs changed as the fiber's hemicellulose content reduced. The properties of PFs fiber suggest that it could be used instead of glass fiber.
