| Résumé : |
The variation on the microstructure of Crocodylus niloticus skins in the tanning process was observed and analyzed by using frozen section staining, which provide the reliable theoretical basis for Crocodylus niloticus leather production. The research on aldehyde fuchshin staining method showed that elastic fiber will receive a lot of damage in the bating and bleaching process. Through the observation of wet blue leather by scanning electron microscopy, the preparation work section and tanning process design are reasonable, also, inter-fibrillary substances had been well removed. The crosscut microstructure of Crocodylus niloticus hides before and after fatliquoring was observed by nile blue sulphate staining method, and the results showed that fatliquor could penetrate into the skin uniformly. |
