In this study, the mechanical properties and preferences of natural and artificial leathers were analyzed. The leathers were classified based on mechanical properties affecting their preferences. The mechanical properties of the leathers were measured via the KES-FB system, and an expert survey was conducted to evaluate leather preference. Leathers possess different mechanical properties depending on the manufacturing process and structural characteristics. Furthermore, differences were observed in the mechanical properties of natural and artificial leather. The mechanical properties of the leathers were related to the preferences for hand and bags. Accordingly, the leather was classified into three clusters. The leathers that were preferred for hand were not preferred for bags, and those preferred for bags were not preferred for hand. Therefore, different development strategies are needed, depending on the type of leather. Natural leather for bags should be light and have good compression elasticity along with its existing mechanical properties, whereas artificial leather should be light and have improved tensile resilience.

天然皮革和人造皮革的力学性能和偏好，以及它们的分类，以箱包皮革为重点

在这项研究中，分析了天然皮革和人造皮革的机械性能和偏好。根据影响其偏好的机械性能对皮革进行分类。通过KES-FB系统测量皮革的机械性能，并进行专家调查以评估皮革偏好。皮革根据制造工艺和结构特征具有不同的机械性能。此外，观察到天然皮革和人造皮革的机械性能存在差异。皮革的机械性能与手和包的偏好有关。因此，皮革被分为三类。喜欢手用的皮革不喜欢包包，喜欢包包的皮革不喜欢手用。所以，根据皮革的类型，需要不同的开发策略。用于箱包的天然皮革应重量轻且具有良好的压缩弹性以及现有的机械性能，而人造革应重量轻并具有更好的拉伸回弹性。
