Abstract
Hemp fibers are increasingly recognized for their strong potential in sustainable textile manufacturing due to their mechanical resilience, low environmental footprint, and versatility in advanced applications. This study investigates how nitrogen fertilization rates, harvest stages, and annual climatic variation affect the tensile properties of hemp fibers. Specifically, breaking force and elongation were evaluated across two growing seasons under controlled cultivation and harvesting conditions. The results demonstrate that moderate nitrogen inputs (N60 and N120) consistently yield superior mechanical properties, while excessive nitrogen (N180 and N240) deteriorates fiber performance. Early harvest stages, particularly before flowering, provide fibers with the highest strength and elongation. Interannual variability was significant, with 2019 outperforming 2020 in most parameters due to more favorable weather patterns. The findings emphasize the critical role of optimized agronomic management in maximizing the textile quality of hemp fibers. This study supports the growing use of hemp as a viable raw material for high-performance and environmentally responsible textile applications.
