Specialists of Shebekinskaya industrialnaya khimiya, LLC (Russia) at several tanneries have worked out recipes for obtaining shoe, haberdashery and belt leathers using a combination of vegetable tanning agents: "MIMTAN AT1", "MIMOSA CR", "MIMOSA RG".
The trials were done on crusts with thicknesses 1.0-1.2 mm, 1.2-1.4 mm, 1.4-1.6 mm, 1.6-1.8 mm, 2.0-2.2 mm, and 3.0+ mm. The leathers were evaluated in crusts and after finishing. The test result is positive. In all variants, the tightness, elasticity and absence of belt crust looseness are noted. All leathers have good fastness results: tensile strength and elongation.
The leathers in the thickness of 1.0-1.2 mm and 1.2-1.4 mm were evaluated after milling. The leathers have pleasant touch, fine grain after milling, good filling and tight grain over the entire area of the leather.
Leather finishing was carried out with the chemicals of the company PIELCOLOR, S.L.U. (Spain). As a result of the trials, orders for these chemicals for doing extended experimental and production batches were received from tanneries.
