Characterization of Leather Structure via Metallographic Sample Preparation

Abstract

In this paper, the leather cross-sectional images based on metallographic sample preparation were introduced, including those of the vertical cross section of the grain layer and reticular layer, the fine fiber cross section and the black outlines surrounding the fiber bundles sections etc. The differences between the images of fiber bundles sections obtained by the light transmission mode and by the light reflective mode were explained. With the introduction and explain of this article, the images obtained by metallographic sample preparation can be well understood.
