The development concerns technologies that provide the formation of the structure and operational properties of the leather using modified dispersions of montmorillonite in tanning and post - dipping processes intended for the manufacture of leather goods of various target orientation. For example for top of footwear, clothes and haberdashery.
Main benefits of development
New technologies provide an increase in the efficiency of using leather raw materials by 3, 1 - 5, 0% , grade of finished products by 5 - 7% , Allow to reduce the cost of enterprises for chemical materials, to expand the assortment materials for the production of leather.
Partially or completely replace the use of environmentally harmful chromium compounds for tanning, to achieve the import substitution of syntans, tannins and fats in post - combustion processes.
The essence of the development
Composite materials were obtained on the basis of aggregatively stable anionic and cationic dispersions of montmorillonite. Their application in tanning and post - dying processes of skin production provides a high level of formation of structure and improvement of skin properties.
The technology of tiling, filling, painting and emulsion greasing of leather semi - finished products in the manufacture of leather for the top of the shoe is developed.
Intellectual Property Protection Status
9 patents of Ukraine were obtained for utility model
The developed technologies could be used by the leather enterprises of Ukraine in order to produce high - quality, competitive leather products and promote the ecologization of leather production.
The state of readiness of development
The development has passed the production testing and is ready for implementation.
