Products made from natural materials are eco-friendly. Therefore, it is important to supply product developers with reliable information regarding the properties of natural materials. In this study, we consider a widely used natural material called jute, which grows in Bangladesh, India, and China. We described the results of tensile tests on jute yarns, as well as the energy absorption patterns leading to yarn failure. We have also used statistical analyses and possibility distributions to quantify the uncertainty associated with the following properties of jute yarn: tensile strength, modulus of elasticity, and strain to failure. The uncertainty and energy absorption patterns of jute yarns were compared with those of jute fibers. We concluded that in order to ensure the reliability and durability of a product made from jute, it is good practice to examine the material properties of yarns rather than those of fibers.
由天然材料制成的产品是环保的。因此，向产品开发者提供有关天然材料特性的可靠信息很重要。在本研究中，我们考虑一种广泛使用的天然材料——黄麻，它生长在孟加拉国、印度和中国。我们描述了黄麻纱线的拉伸试验结果，以及导致纱线断裂的能量吸收模式。我们还使用统计分析和可能性分布来量化与黄麻纱线以下特性相关的不确定性：拉伸强度、弹性模量和断裂应变。将黄麻纱线的不确定性和能量吸收模式与黄麻纤维的进行了比较。我们得出结论，为确保由黄麻制成的产品的可靠性和耐用性，最好检查纱线的材料特性而非纤维的。
