29-01-2025

       The specialists of Shebekinskaya  industrialnaya  khimiya, LLC  have  conducted a technological visit to the tannery in order to test dyeing-fatliquoring recipes.  Recipes of obtaining the following  articles have been tested: "Shoe Nappa", "Garment  leather", "Split" using chemicals from Shebekinskaya  industrialnayakhimiya, LLC (Russia) and Dowell (China):

1. Nappa is obtained using a combination of acrylates: "Dowelltan RS-16" and "Dowelltan RE-17". «Dowelltan RS-16»  is an acrylic acid—based  retanning agent that makes the leather soft and light.  «Dowelltan RE-17» —  a retanning agent based on acrylic resin, gives fullness, softness, provides high elasticity, excellent light and heat resistance, improves the leather ability to buffing. As a result, the obtained crust looks good, elastic, without looseness, and after milling, there is also slight uniform grain.
2. The government leather is obtained using a polymer  «Dowellmeta MF». «Dowellmeta MF» is a multifunctional polymer filling  retanning  agent, which has retanning and greasing properties, gives the leather exceptional softness and lightness, which is suitable for the production of light articles, partially or completely replaces retanning agents and fat liquors, greatly facilitating the leather production process, effectively  improves  the values of physic-mechanical parameters of the leather. Due to its excellent light and heat resistance, it can be used for fatliquoring light and white leathers. As a result, the obtained crust looks soft, light enough, and milled very quickly. The customer  liked touch of the finished article. The customer plans  to sew a men's jacket from the obtained article in his own sewing production and evaluate the properties of the leather in the finished product.
3. In the recipe of the article "Split for finishing", Evrosintan VA, manufactured by Shebekinskaya  industrialnaya  khimiya, LLC (Russia), was used to solve the problem of obtaining tighter leather. “Evrosintan VA” is an auxiliary agent for impregnation of suede leather and split in a drum. The product strengthens the fibrous structure of the split; improves  the  ability to buffing and ensures obtaining short hair; helps to obtain smooth surface. The article is positively evaluated.
