Abstract

A review of the literature shows that to this day there is no consensus among researchers explaining the phenomenon of the two-bath chrome tanning method. Very high elastic-plastic properties of two-bath tanned fur with hard to imagine high strength properties compared to fur tanned using a single-bath method. There are also no convincing arguments for the practical abandonment of this method. Arguments about the bulkiness and high consumption of chemical materials, at least in today's concept of production efficiency, are not entirely convincing, because the described quality and consumer properties of fur of this type of tanning can justify high costs. A more compelling argument for rejecting the two-bath tanning method is the low heat resistance of fur, which makes it unsuitable for use where high temperature conditions are used to make products from it. Therefore, this work examines the possibility of increasing the thermal stability of semi-finished fur products. During the experiment, a semi-finished fur product with a specified heat resistance was obtained.
