Steam-Thermal Modification of Hemp Fiber to Improve the Performance Properties of Textile Packaging

The paper investigates the influence of steam-thermal modification parameters on the structural and mechanical properties of hemp fibers ( Cannabis sativa L. ) intended for textile packaging applications. Experimental dependencies and graphical relationships illustrating the effects of pressure, temperature, and treatment duration on tensile strength and elongation at break are presented. The approach is based on the assumption that targeted modification of the lignocellulosic structure, particularly the partial removal of amorphous components, governs the deformation behavior of the fibers. It was established that steam-thermal treatment leads to a reduction in elongation, improved dimensional stability, and optimization of the stiffness–flexibility balance. The reliability of the proposed approach is confirmed through experimental evaluation of mechanical and structural characteristics, demonstrating the suitability of modified hemp fibers for durable and ergonomic textile packaging.
