  Abstract

This work aims to reveal how the alkali influences the mechanical behavior and structural stability of palm fiber. First, palm fiber samples were treated with 20 % and 40 % NaOH solutions separately for approximately 1, 2, 3, and 4 h at room temperature. Then the samples were characterized using tensile testing, Fourier transform infrared spectroscopy, X-ray diffraction, and thermogravimetric analysis. Results showed the tensile properties of alkali-treated fibers exceeded those of untreated fibers. Notably, the fibers treated with 40 % NaOH for 1 h yielded the most significant improvements. The tensile strength, elongation at break, Young셲 modulus, and yield point increased by 28.8 %, 38 %, 52.1 %, and 64.7 %, respectively, compared with the untreated fibers. The increase appeared to be due to the removal of non-cellulosic materials and rearrangement of the cellulose chains.
