Abstract: 
The research has been carried out to study colloid-chemical characteristics of stagewise formation of structured leather semi-finished product. It is established that the activity of basic chromium sulfate complexes increases significantly while transition from anion form to cation one. During plastication of dermis structure by alkyl carboxy ethanolamine tannins, diffusion of basic chromium sulfate complexes into dermis accelerates and therefore provides a high level of chemical structuring of collagen of the dermis. Environmentally-effective technologies were designed for chrome tanning in production of leather rawhide Wet-blue and non-chrome tanning for producing leather semi-finished products of polyfunctional application
