Innovative Leather Composites in Construction: Environmental Performance of Modified Silk Hydrolysate Fillers

This article studies the chemical, physical, and mechanical properties of leather filled with modified silk hydrolysate. During the study, a scanning electron microscope with a JSM-IT200 SEM microanalysis system was used to study the morphology of the leather tissue surface. According to the article, the morphology of the surface of the material was studied, as well as the distribution of chemical elements was determined, and the image of the object was taken with a wide range of magnification. Fibrils adsorbed with modified silk hydrolysate were less mobile than the adjacent structural wraps and stronger than the fibers in the control leather fabric. Compared to experimental leather samples not treated with modified silk hydrolysate, the content of Cr, Ca, Na, K, S, and other substances in experimental leather samples treated with modified silk hydrolysate remained unchanged. However, we can see that the N (nitrogen) content of the sample treated with modified silk hydrolysate increased by 43.7%, O (oxygen) by 13.3%, and C (carbon) by 33.3%. An increase in the amount of N (nitrogen), O (oxygen), and C (carbon) in the samples indicates that the modified silk hydrolysate has chemically reacted with the leather tissue fibers and formed chemical bonds.
