Simple identification method of pig, cattle and sheep split leather

Abstract

The invention provides a simple identification method of pig, cattle and sheep split leather. The simple identification method includes following steps: S1, cutting an opening at any position of the split leather, clamping two ends of the opening on upper and lower clamps of a tensile machine respectively, starting the tensile machine, and tearing the split leather along the opening, wherein tearing length is higher than 100mm; S2, cutting to obtain a split fiber tissue sample strip, wherein a fiber bundle contained by the sample strip is uniform in length distribution and has representativeness; S3, putting the sample strip under a microscope, observing, and taking a microscopic picture, measuring length and thickness of the fiber bundle through microscope workstation software, and recording morphological characteristics of the fiber bundle; S4, comparing the taken microscopic picture, the measured length and thickness of the fiber bundle and the recorded morphological characteristics with pre-stored known sample spectra, and identifying whether a leather sample is made of pigs, cattle and sheep. By the method, identification of the pig, cattle and sheep split leather is simpler and more effective, and identification difficulty caused by the fact that cross section characteristics are not obvious is reduced.

Description

technical field [0001] The invention relates to the technical field of leather material identification, in particular to a simple identification method for pig, cattle and sheep split leather materials. Background technique [0002] At present, there are various methods for leather material identification, the simplest and most effective is to observe the leather grain pattern through a microscope. In the Chinese patent application document with application number 201210288246.4, a simple identification method of leather fiber structure is disclosed, which is mainly identified by observing the cross-sectional morphological characteristics through a microscope. However, the inventors of the present invention have found through research that when the sample is a split leather material, because there is no grain pattern, if only observing from the cross section, and there is no papillary layer feature on the cross section, the identification often appears to be more difficult. ...
