Study of the Microstructure of Crocodylus Niloticus Skins During Leather Making Process

Abstract

The variation on the microstructure of Crocodylus niloticusskins in the tanning process was observed and analyzed by usingfrozen section staining, which provide the reliable theoreticalbasis for Crocodylus niloticus leather production. The researchon aldehyde fuchshin staining method showed that elastic fiberwill receive a lot of damage in the bating and bleaching process.Through the observation of wet blue leather by scanning electronmicroscopy, the preparation work section and tanning processdesign are reasonable, also, inter-fibrillary substances had beenwell removed. The crosscut microstructure of Crocodylusniloticus hides before and after fatliquoring was observed by nileblue sulphate staining method, and the results showed thatfatliquor could penetrate into the skin uniformly.
