| Summary: | Considerable amount of information is known on the use of natural minerals as ion exchangers, sorbents, catalysts for solving environmental problems, wastewater treatment. However, papers on the use of minerals in the manufacture of leather as a material that can adjust and regulate the efficiency of the dermis structure formation and the relevant properties of finished leather in the literature are very rare.
This paper focuses on particular aspects of the use of naturally occurring minerals in the tanning industry and the ability to create a high-performance structure of dermis with the predicted performance and hygienic indicators through a comprehensive selection of technologically efficient materials on mineral basis.
The effectiveness of application of montmorillonite and zeolite minerals and organic-mineral composition based on them for filling–retanning of leather semi-finished product has been analyzed. The use of finely-dispersed minerals promotes alignment of topographic areas in thickness, increases the yield of the leather in the area by avoiding bonding structural elements of the dermis. Changes in the microstructure of the dermis as a result of mineral filling contribute to the improvement of performance and hygienic properties of finished leather, increase the efficiency of use of raw materials, reduce costs for chemicals, expand the range of materials, increase the production of environmentally friendly leather, increase the competitiveness of the production of domestic and global markets. |
