ИЗУЧЕНИЕ СВОЙСТВ ХРОМОВОГО ЭКСТРАКТА, ПОЛУЧЕННОГО ИЗ СОСТАВА ДЛЯ ПРЯМОГО ДУБЛЕНИЯ

Abstract

Many research and experimental works are devoted to the chemistry of chromium, its interaction with collagen and methods of application. However, to this day, the sum of these works has not made it possible to combine even the well-known positive properties of chromium in one method. Therefore, when the quality indicators of products on the world market received high priority and the demand for fur with high physical and mechanical properties increased, one of the promising directions in chrome tanning is the improvement of tanning methods by restoring chromium directly on the dermis fiber, which, in the modern concept of tanning theory, can provide fur of higher quality and exceed the currently achieved limits of strength properties. For this purpose, a series of experiments was carried out to obtain a chrome tanning agent of a new composition. The results of the data obtained show that the new chrome tanning agent, obtained by reducing the composition used for direct tanning in solution, has slightly different technological properties, which are manifested in the properties of the finished fur.
