Abstract

The possibilities of reducing the negative impact of chrome tanning agents on the environment are considered. Special attention is paid to the chrome-saving technology of dressing fur raw materials with pretreatment with non-toxic non-isocyanate urethanes. The results of a study on reducing the concentration of chromium in the working solution using functional non-isocyanate urethanes are presented. The object of the study is the raw material of fur sheepskin. It was revealed that the introduction of pretreatment with non-isocyanate urethanes before chrome tanning of fur raw materials allows reducing the initial concentration of chrome tanning agent in the bath to an average of 37%.
