A Simple Identification Method of Leather Fiber Structure

Abstract

The invention relates to the technical field of identification for leather materials, in particular to a simple identification method for a leather fiber structure. The simple identification method includes: firstly, flattening an original leather sample and preconditioning for 48 hours in atmospheric conditions; secondly, fabricating the leather sample subjected to preconditioning to a section test sample, and standing in the atmospheric conditions; thirdly, placing the stood section test sample into a super-depth-of-field three-dimensional video microscope for visualization, and shooting microscopic images; and fourthly, identifying the leather fiber structure according to leather section microscopic characteristics displayed by the microscopic images. The simple identification method for the leather fiber structure has the advantages that complicated procedures of ultrathin section, dyeing and the like in a traditional tissue section process can be omitted, and the simple identification method is simple in sample preparation, small in leather fiber deformation, clear in edge contours and internal characteristics and capable of accurately reflecting the leather fiber structure, and the like.

Description

technical field

[0001] The invention relates to the technical field of identification of leather materials, in particular to a simple identification method for leather fiber structure. Background technique

[0002] Leather is a kind of biological tissue. To understand the structure and shape of various raw leather and its changes in the production process, it must be studied through histological methods. At present, it is mainly through scanning electron microscopy (SEM), transmission electron microscopy (TEM) ), atomic force microscopy (AFM) and optical microscopy (LM) to study the fiber morphology.

[0003] The use of tissue section observation to study the fiber changes of animal leather before and after processing has been very mature. Since the 1950s, it has been used to study pigskin, sheepskin, rabbit skin, deerskin, snakeskin and other leather and fur in China. , the observation results are used to guide the processing and production and the research and development...
