New Tanning Agent with Montmorillonite for Leather Manufacturing

Article Preview

Abstract:

The article is devoted to the investigation of the efficiency of chromium-modified montmorillonite dispersions to stabilize the collagen structure of the dermis. The interaction of modified dispersions of montmorillonite with collagen of the dermis was studied with the use of IR spectroscopic studies method. The high level of absorption of chromium compounds and their reduction by 30 % in the exhaust fluid was found. The use of montmorillonite dispersions provides qualitative formation of the structure of the dermis and physical and mechanical properties, with a reduction of tanning agents’ costs/waste by 16 %.
