Abstract: The main results of the study of the diffusion of fillers in the structure of chrome leather are presented. The effect of fillers on the air – and water permeability of leather is shown. The products of protein hydrolyzate of chrome-plated leather wastes and modified protein hydrolysates with acrylic acid and plasticized with glycerin were prepared. Leather prototypes are filled with protein hydrolyzate products. The control leather is filled with barium chloride, molasses and potassium alum. The diffusion of the fillers of experimental and control samples of leather with both the front and the bahtar side was investigated. The water resistance of the leather treated with the studied fillers confirms that repeated cycles of watering and drying of the leathers practically do not change the indicators of wettability. Uniform diffusion is observed when using barium chloride and alumino-potassium alum. In the leather samples of used molasses, its uneven distribution over the thicker leather and salinity is observed. The porosity of the prototypes of the leather and, consequently, their air permeability after filling is reduced in comparison with the control samples.
