The main objective of the study was to chemically modify plant fiber surfaces, with silanization proving to be the most effective method in enhancing fiber thermal stability and moisture resistance. Additionally, mercerization and benzoylation methods also yielded satisfactory results in improving fiber properties.
The main aim of this study was to chemically modify the plant fiber surface. Hemp, flax fibers and cotton trichomes were subject of surface treatments using silanization, acetylation, benzoylation, and mercerization processes. The fiber properties were evaluated with the use of fourier transform infrared spectroscopy (FTIR), scanning electron microscopy (SEM), wide-angle X-ray analysis (WAXS) and thermogravimetric analysis (TGA). Additionally, humidity and color of the modified fibers were evaluated. Chemical treatment of the plant fibers reduced their hydrophilic nature, increased the moisture resistance, and improved their thermal stability. In all the cases the silanization process proved to be the most effective method of improving fiber thermal stability and moisture resistance, yet mercerization and benzoylation methods offered satisfying results as well.
