METHODS OF DEGREASING SHEEP AND FUR SKINS

Abstract

This article shows the most effective methods of degreasing fur and sheepskin, provides detailed information about the use of emulsions in degreasing, methods of using various chemical compounds. The temperature, duration and concentration of detergents are important for degreasing. Degreasing processes using strong and weak chemical methods can be considered on skins of sheep and furs. When degreasing g. k., temperature, duration and concentration of detergents Degreasing degree of sheepskin hair acetic anhydride acidified with sulfuric acid (5 ml of concentrated chemically pure sulfuric acid is added to 2 ml of acetic anhydride) hair has a green color is determined by the lack of This reaction is called cholesterol or Lieberman reaction.
