Testing the dyeing-fatliquoring recipe with the use of Shebekinskaya industrialnaya khimiya, LLC chemicals.

21-05-2025

        A technological visit had been conducted at one of the tanneries in Belarus, during which the dyeing-fatliquoring recipe was tested for articles: "Cow lining" and "Shoe crust" for further finishing in a thickness of 1.2-1.4 mm, with a positive result. The recipes were tested using chemicals from Shebekinskaya  industrialnaya  khimiya, LLC (Russia):

• «SMH-470» - synthetic fat liquor of anionic character;
• «SMH-473» - fat liquor based on natural and synthetic sulfonated fats;
• «SMH-477» - fat liquor based on sulphited and sulfonated natural and synthetic oils that comply  with the requirements of the REACH regulation;
• «SMH-479» - NOVELTY, mixture of natural, sulfonated and synthetic oils that meet the requirements  of the REACH regulation. The product is developed for fatliquoring  of chrome-tanned, vegetable-tanned and mixed-tanned  leathers. On all types of the leather, the fat liquor is evenly distributed over both the area and the thickness of the leather, giving the leathers oft and tight  grain, pleasant touch, while increasing elasticity and tensile strength. The  high concentration of the solids allows to achieve good fatliquoring results with minimal consumption;
• «SMH-478» - NOVELTY, concentrated  fat liquor based  on a mixture of natural, synthetic, sulfonated  and  sulphited  natural oils that meets the requirements of the REACH regulation. It is used for soft filled leather articles. It is recommended to use it with other fat liquors to give softness and natural  touch. On all types of leather, the fat liquor is evenly distributed over both the area and the thickness of the leather, giving the leathers oft and tight  grain, pleasant touch, while increasing elasticity and  tensile  strength. The high concentration of the solids allows to achieve good fatliquoring  results with minimal consumption. The composition does not lighten dyes, which allows to get bright, saturated colour.

All the crusts were positively evaluated  by the tannery managers. The recipes were given over to calculating the cost of treating. It is planned to order new chemicals for extended trials.
