对不同粘合温度下的热点粘合非织造布的拉伸模量、最大拉伸应力和最大应力下的伸长率等力学性能进行了评价。图像采集和分析技术已被用来量化的结构参数，如纤维取向分布函数，粘结区的应变，和单位细胞应变在受控变形实验，并确定故障机制。我们已经表明，在控制变形实验过程中发生的结构变化的原位实验可视化和测量可以帮助建立非织造织物的机械性能和结构性能之间的联系。
The mechanical properties, namely, tensile modulus, maximum stress in tension and elongation at maximum stress of thermally point-bonded nonwoven fabrics with different bonding temperature have been evaluated. Image acquisition and analysis techniques have been used to quantify structural parameters such as fiber orientation distribution function, bond-region strain, and unit cell strain during controlled-deformation experiments and to identify failure mechanisms. We have shown that an in situ experimental visualization and measurement of the structural changes occurring during controlled-deformation experiments can help establish links between mechanical properties and the structure properties of nonwoven fabrics.
