Visits on introduction of chemicals and recipes of Shebekinskaya industrialnaya khimiya, LLC (Russia) were conducted at tanneries. The emphasis was placed on new products: "SMH-477", "PC 2026S". • «SMH-477» — a product for fat liquoring leathers of chrome, vegetable and mixed tanning. The fat liquor is evenly distributed over both the area and the thickness of the leather, giving the grain softness and tenderness, pleasant touch, while increasing elasticity and tear resistance. • "PC 2026S— pigment concentrate for finishing white leathers with enhanced whiteness. The partners are offered the recipes of soaking-liming-tanning processes, dyeing-fatliquoring processes and finishing. The visits were carried out with positive results: orders were received, chemicals were ordered for testing recipes and the terms of technological visits were agreed....

     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".

  • "MIMTAN AT1" - has excellent dispersing properties, facilitates the penetration and distribution of vegetable tannins ("Mimosa RG") and dyes.
  • «MIMOSA CR» - the combination of modified mimosa and chromium; has a low pH (2.8), which facilitates the process of fixing tannins and dyes, therefore gives the leather fullness and tightness, as well as smooth fine grain.
  • «MIMOSA RG» - polymerized tannin (increased molecule size) with strong filling properties; in combination with "Mimtan AT1" is distributed to looser areas of hides and skins.

      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.
