Deer leather has a characteristic pattern, referred to as 'pebble', which is accorded such importance that a lack of it renders a leather defective. Synchrotron-based small-angle X-ray scattering (SAXS), ultrasonic imaging, scanning electron microscopy, and tear tests were used to investigate the structural characteristics of well-pebbled and poorly pebbled cervine leathers.
Poorly pebbled leather has a less open structure in the upper grain region than well-pebbled leather. The orientation index (OI) of leather with a poor pebble is less than that of the well-pebbled leather, particularly in the corium. The tear strength is also less for the poorly pebbled leather.
The differences in structure between well- and poorly pebbled cervine leathers are not the same as the structural differences between tight and loose bovine leathers, to which they are sometimes compared. On the contrary, good pebble may reflect an internal structure similar to that of looseness. It is hoped that methods to prevent a reduction in pebbling during the processing of cervine leather may be developed by applying this knowledge of cervine leather's structural characteristics. © 2017 Society of Chemical Industry.
鹿皮具有一种被称为“卵石纹”的特征图案，其重要性极高，缺少该图案会使皮革成为次品。基于同步加速器的小角X射线散射（SAXS）、超声成像、扫描电子显微镜和撕裂试验被用于研究具有良好卵石纹和卵石纹不佳的鹿皮革的结构特征。
卵石纹不佳的皮革在上层粒面区域的结构比卵石纹良好的皮革更为致密。卵石纹不佳的皮革的取向指数（OI）低于卵石纹良好的皮革，尤其是在真皮层。卵石纹不佳的皮革的撕裂强度也较低。
卵石纹良好和不佳的鹿皮革之间的结构差异与有时被拿来比较的紧密和疏松牛皮革之间的结构差异不同。相反，良好的卵石纹可能反映出一种类似于疏松结构的内部结构。希望通过应用这种关于鹿皮革结构特征的知识，能够开发出在鹿皮革加工过程中防止卵石纹减少的方法。© 2017化学工业协会。
