ARTICLE ANNOTATION

quote
During the research, a technology was developed for tanning cattle hides using local tannins instead of imported ones from abroad. In this work, for the first time, the possibilities of using furfural tanning agent for tanning cattle hides, as well as the physicochemical properties of cattle hides, were studied. This includes three experimental samples of cattle hides treated with hydrocyclical compounds (furfural) and micrographs of cattle hides treated in the traditional way. The appearance of these variants was presented on 3 different micrographs, the surface, sides and faces were selected, and the results of morphological and conformational changes in the surface and internal structure of these samples were presented using an RoHS model (equipped with a digital camera with a pressure of 2 MPa), a digital optical sensor using a microscope and based on it, the furfural dye was obtained for processing the skins of large horned animals. Two identical hides of cattle were selected to compare the results of experimental tests. These hides were processed in the traditional way using furfural tanning agent, and the results of tanning the hides with these methods were compared. The influence of the tanning process on cured cattle hides prepared in the traditional way using furfural tanning agent was studied. The skins treated with furfural tanning agent had high hydrothermal stability, and the skins treated with furfural tanning agent had complex properties and met the requirements of GOST 939-2021. The results of morphological analysis of leathers isolated using furfural tanning agent are presented.
